hello all this is an update to the highly viewed post I authored over 1 year ago - in that time it has accumulated 190 replies and is the most viewed posting in the entire charging forum 27,686 views as of April 2018 (vs. the next most viewed post at 17,986)

http://www.chevybolt.org/forum/82-charging-batteries/7138-charging-opinions-long-time-ev-user.html

From the original date to today things have changed (progress is sooooo awesome). So I have reviewed the entire thread and updated the original posting to integrate/summarize consolidated information and updated some of my recommendations in light of new information and new products that were not available at the time of the original posting.

I wish to thank all forum members for their input and corrections for my original post, we are stronger as a team and just because I'm posting this does not mean I did this all on my own - thank you all for your input. I'll humbly note however I believe the original post as aged pretty well, and while my original assertions about charging were met with some skepticism I believe the forum community has come around and largely agrees with the recommendations from the original post.

the updated version is being provided mostly for new forum members so they don't have to slog through the original post and piece together the best practices as things changed and the post was updated over the past 14 months.

if you have read or kept up with the original thread I do not believe there is any new/insightful information in this posting

again it's just a consolidation and optimization since much has changed since the original posting (for example I don't think anyone should buy a "modified" Tesla charger anymore, just get the adapter).

no no new information for long time readers, but a more concise read if you're not up to speed from the previous thread.

Hello all,

long time EV customer, 1 year Bolt owner - woot - what a great car! Have one for the family and we all love it!!

I've been driving EV's for about 5 years (Ford Focus EV, Tesla Model S, Tesla Model X, Bolt and Leaf). Over that time I've developed my opinions about charging and I'm going to share them here for all to see and learn - LOL

1st off kudos to Chevy on this car - I've added it to my EV fleet and continue to be very happy with the car (except for the seats - oh the seats) - but after coming from Tesla I found the charging information/situation with Chevy to be lacking.

1. The 110v charger (L1) included with the car is mostly pointless. I highly recommend upgrading to a more capable 240 volt charger (32 amp or 40 amp) - either portable or stay-at-home.

The Best mobile charger in my opinion is a Gen-2 Tesla Universal Mobile Charger (UMC - $320). Carry one of these babies in your Bolt and you can charge _ANYWHERE_ - it’s a very reasonable 32 amp charger for it’s price in that you can use virtually any AC plug you run into.

https://shop.tesla.com/us/en/product/vehicle-accessories/model-s_x_3-gen-2-mobile-connector-bundle.html

for those of you not familiar with the Tesla Gen-2 UMC it supports the following charge rates via various adapters you can buy from Tesla…

The Gen-2 Tesla UMC comes with two included plug adapters - NEMA 5-15 (normal house hold plug) and NEMA 14-50 (RV Park 50 amp 240 volts - Bolt will charge at 32 amps)

You can purchase additional adapters ($35 each) allowing to potentially charge at home or on the road with the following plug types
NEMA 10-30 (30 amps - 24 amp charge rate), NEMA 14-30 (30 amps - 24 amp charge rate), NEMA 5-20 (20 AMP/120 volt, 16 amp charge rate - Bolt is limited to 12 amps), NEMA 6-15, NEMA 6-20, NEMA 6-50

Of these adapters I recommend the following:
NEMA 10-30 - old style electric Dryer/Waterheater plugs - charge at family’s house while visiting if they have an electric dryer or water heater
NEMA 14-30 - new style electric Dryver/Waterheater - see above
NEMA 6-50 - these are often found in Mechanic’s shops for arc-welders - 240 volts 50 AMP’s - Bolt will charge at 32 amp limit when you have one of these
You don’t need the NEMA 5-20 adapter - because Bolt is limited to 120 volts @ 12 amps - so there is no point

NOTE: if you have a Gen-2 Tesla UMC with you both the NEMA 14-30 and 14-50 adapters will allow you to charge your Bolt @ 24amps/32amps at virtually _ANY_ RV park - and once you start looking there are more of these than you can imagine (KOA anyone, 99% have NEMA 14-50s you can rent a space for like $10) - so you can go virtually anywhere you can find a camp ground and use an RV-hookup (normally for a very reasonable rate) and charge your Bolt anywhere you can find electricity. I have used many many RV/camp grounds to charge my Tesla's and that allows me to drive EV's pretty much anywhere with no "charging" infrastructure- because all I need is a "plug".

If you chose to go with the Tesla UMC you MUST purchase a JDapter ($239) or TeslaTap ($239)
https://shop.quickchargepower.com/JDapter-Stub-Tesla-Charge-Station-Adaptor-JDPTRSTB.htm
http://www.umc-j1772.com/index.php?route=product/product&product_id=50

This adapter converts the Tesla UMC connector to a standard J-1772 (Bolt) EV charging connector - it allows _ANY_ J-1772 EV to charge from a Tesla L2 charger (NOT superchargers). For those of you that don’t know Tesla supports what they call a Tesla Destination charging network (chargers installed with Tesla’s assistance at various locations all over North America - this chargers vary in Amperage from 20-80 AMP’s and are typically free if you are a customer of the associated business). The link below is an interactive map of all the Tesla L2 Destination chargers - if you have the $239 adapter you can use these charging locations (with permission) in addition to normal J-1772 chargers - so you great expand your potential charging solutions if you have this adapter.

https://www.tesla.com/findus#/bounds/49.38,-66.94,25.82,-124.39?search=destination charger&name=usa

You do not need a “membership/account” with Tesla for use of these chargers, usage is at the discretion of the associated business owners - NOT Tesla. Many of these business have both J-1772 and Tesla chargers on site, and carrying this adapter simply offers you the choice of using a Tesla charger if all the J-1772 chargers are occupied - most business owners won’t care. In some rare cases some businesses have ONLY Tesla chargers and this adapter would let you charge your Bolt should you encounter this situation. This forum has had extensive discussion on this topic and I believe it is well established that this adapter is a MUST have for any serous EV road warrior, even _IF_ you do not plan to use a Gen-2 Tesla UMC for your home charging solution. Links below are useful to review for the Bolt forums knowledge and experience using these adapters (spoiler: people who have them have no problems and love using them).

http://www.chevybolt.org/forum/82-charging-batteries/13490-anyone-tried-tesla-j1772-adapter.html

2. If you don’t want to go the Gen-2 Tesla UMC route (other other chargers) I recommend you at least consider purchasing a well made adapter for the Chevy OEM EVSE included with the Bolt. The EVSE included with the Bolt is dual 120 volt and 240 volt charger. All you need is a passive adapter to allow you to plug the included EVSE into a 240 volt source. If you have this adapter it will double the charge rate for the Bolt’s included charger which will dramatically improve your turn around time when charging the Bolt. This will benefit you both at home and on the road and it’s a simple and very affordable method to improve your charging times and provide more charging options. If you have a 240 volt adapter for your Bolt EVSE it will charge at 240 volts * 12 amps - or 2.88 kw vs. the normal 1.44 kw from a standard household plug.

http://gm-volt.com/forum/showthread.php?218442-2016-Volt-120v-EVSE-is-L1-L2-Conversion-Capable

Home charging this topic has been discussed ad nausea on the Tesla/Bolt forums it comes down to these basic choices.

1. some people don't feel they need one and opt for public/work based chargers - I applaud these people's sprit and they honestly believe this works for them. I'm too much of a control freak to go this route and want to know I can charge my car at a reasonable rate on my own terms.
2. Install a NEMA 14-50 plug in their garage - and this gives you many options as you can buy many many chargers and install them by simply plugging them in.
3. some people have two (2) Tesla UMC's with them - one in car , and one that lives in the garage plugged into the NEMA 14-50 plug or what ever plug they decide to install.
4. some people have one (1) UMC - and their's lives in their garage and they only take it out of the garage when "traveling"
5. Many people opt for the Tesla Wall connector - see link below- the reason for this is safety (hard wired) and configurability - it can be configured to provide 16-80 amps with appropriate circuitry - making it one of the most flexible EV chargers on the market for a fair price ($500) - of course you'll need a JDapter/TeslaTap to use it.
6. My personal recommendation for home charging is to go with either: Tesla Wall connector + Adatper, Clipper creek, JuiceBox, or ChargePoint. The clipper creek chargers are bullet proof and have a wide wide range of charging options (12 amp to 100 amp J-1772 chargers)

Tesla Wall Connector - https://shop.tesla.com/us/en/product/vehicle-accessories/model-s_x_3-wall-connector.html
Gen-2 Tesla UMC - https://shop.tesla.com/us/en/product/vehicle-accessories/model-s_x_3-gen-2-mobile-connector-bundle.html
ClipperCreek - https://store.clippercreek.com/hcs-50-hcs-50P-40-amp-ev-charging-station?search=HCS-50&category_id=69
JuiceBox -

Advice on the install:

1. buy the biggest charger you can handle - even though the Bolt can only pull 32 amps - the Bolt isn't your last EV car, so plan for the future and only buy one of these suckers once. The J-1772 standard covers up 80 amps, and when the charger can provide more power than the car can pull, the car only pulls what it needs.
2. the real cost is the labor, wiring, and main panel modifications - not the actual charger. Cost vary based on how full your panel is, the distance to the charging location, and if you need to upgrade your main panel to have a larger service breaker
3. even with a small breaker - pull the biggest AMP wire you can to the charging location - that way if you can upgrade in the future, you only have to swap the breaker in the panel, and the charger at the other end - and not pull wire again (normally costly) - long runs of high-AMP copper wire are expensive - so be prepared.

The Tesla Wall Charger ($500) has two advantages that push it over the top IMHO…
https://shop.tesla.com/us/en/product/vehicle-accessories/model-s_x_3-wall-connector.html

a) it's configurable - you can set the feed breaker's AMP setting, and the charger will tell the car the max AMP's it can feed, that means you can buy one wall charger, and over time adjust it to what ever AMP's you are feeding it making it the most cost effective chargers out there for the widest range of possible charging rates…
b) it also has the ability to be "daisy chained" with up to 3 other Tesla Wall Chargers (1 master and up to 3 slaves configured by dip-switches in the charger) - and 2-4 chargers will SHARE a single circuit breaker and adjust the AMP load based on demand from the car's being charged (this is part of the J-1772 standard). So you can install one circuit, one wall charger, and in the future "add" another Wall charger and charge 2, 3, or 4 electric cars off one (1) electrical circuit - for the future multi-EV household I consider this a killer feature and is why I give the nod to the Tesla Wall Connector for $500.

I personally have been running a 3 charger 60 amp circuit setup with Tesla/Bolt/Leaf for the past year (and JDapter's)- it works great - I plug 3 cars in - and they all share the single 60 amp circuit during off peak charging window (48 amp charge rate). The only down side so far from this setup is:

1. I occasionally have to cycle the breaker as the chargers get confused and show a "red blinking" light about once every 8 weeks
2. chevy Kindly informs me that my charging sessions has been interrupted when ever the AMP load changes due to one of the other cars finishing their charge - this "interruption" is false, and it's simply the EVSE's adjusting the reported AMP load based on the drop in demand from one of the other cars.

So for me the ideal charging scenario for a Bolt Owner is:

1. Gen-2 Tesla UMC in the trunk with many adapters for all plugs - https://shop.tesla.com/us/en/product/vehicle-accessories/model-s_x_3-gen-2-nema-adapters.html
2. Tesla Wall connector in the garage configured to match the maximum AMP's my home electrical panel can handle (plus Adapter)
3. JDapter/TeslaTap in the car for charging using Tesla destination chargers while out and about on trips
4. Some extension cords to help reach plugs while traveling if necessary

I also recommend the following items from amazon for the road warrior charging master:

1. high quality 20 amp extension cord - https://smile.amazon.com/AC-Connectors-S520PR-025-Anti-Cold-Extension/dp/B07215SHYT/ref=sr_1_3?ie=UTF8&qid=1523718056&sr=8-3&keywords=20+amp+extension+cordnema
2. short adapter that let you plug the 20 amp extension cord into a normal 15 amp plug - https://smile.amazon.com/AC-Connector-S515520-012-1-Foot-Adapter/dp/B06XGL2HLL/ref=sr_1_4?s=hi&ie=UTF8&qid=1523718123&sr=1-4&keywords=nema+5-15+to+5-20+adapter
3. NEMA 14-50 extension cord - heavy and expensive, but a life saver sometimes when you just can't reach that juicy, ever so fast, 40 amp 240 volt plug that is just out of reach… https://smile.amazon.com/Camco-Extension-PowerGrip-Convenient-Carrying/dp/B002XL2IG8/ref=sr_1_4?s=hi&ie=UTF8&qid=1523718177&sr=1-4&keywords=nema+14-50+extension+cord

congrats everyone on your Bolt! I love mine and I know you'll love yours - these recommendation are investments in my opinion and modified Tesla's chargers will serve you well for _ANY_ EV you currently own or likely will own in the future.

Great post. My only comment would be this: while it's great to have a portable charger in the trunk (and I totally agree that a Tesla Gen2 UMC with J-Adapter is the best way to do this), it's really not needed unless you're the kind of person who expects to be driving the Bolt beyond range of home. And because the Bolt has such a long range that's not likely to be a very frequent occurrence for most people. A portable charger isn't something you'll need unless you're on the road and can't find a standard public charging station.

If you're a prospective Bolt purchaser and you're wondering about charging, chances are you won't have to worry about getting a portable charger. And for many people the only piece of extra equipment you'll need is the adapter that lets you plug the included "charge cord" (EVSE) into a 240V outlet - that'll get you around 100 miles of added range on an overnight charge.

To sum up: if you have access to a 240V plug then you can drive the Bolt on local trips around town without needing any expensive charging equipment.

Great info!

Thanks to all for the great info in this and the earlier thread on charging and EVSEs. I've struggled with which mobile Level 2 EVSE to get for my Bolt, but have decided to take the plunge and buy a Tesla Gen 2 Bundle plus the 14-30 and 6-50 adapters. Sadly, there are not as many public charging options in my area of U.S., so having a backup plan in the trunk should give me more freedom (and courage) to venture out! :)

I apologize if this is the wrong thread but I would like some input from the group on my two charger options that I'm considering right now:

1) The AV EVSE-RS direct wire 32A / 25ft cable runs $549 on average. It does not have any networking or reporting. It is a simple charger.
2) The JuiceBox PRO 32 direct wire 32A / 24ft cable runs $499 on average. It is WIFI enabled and has those 'features'
3) The JuiceBox PRO 40 direct wire 40A / 24ft cable runs $549 (on sale). It is WIFI enables as the model above.

Can someone shed some light on any differences that are not apparent in the website?

The price difference is not more concern, I want to buy the better product ... a good product.

Thanks,
Bill

I bought a JuiceBox Pro 40. I like it.

You can use it as a dumb charger (it doesn't need to connect to WiFi to work), but the added features for monitoring and reporting are very nice. It's kinda fun to watch the various status dials as the car charges.

It's also nice that if you want to limit the charging rate, you can. I used that for a while when I was plugging into a dryer outlet, and I've also used it to limit how much power the car draws when preconditioning.

I found a Juicebox Pro 40 on Ebay that was factory refurbished and came directly from the factory. Saved tax, shipping & got a great deal with the full JuiceNet functionality.

By that same action, I have a gently used Siemen's Versicharge 30 Amp EVSE I'd be willing to part with if anyone is interested - PM me. I'll get some photos & get it posted in the Marketplace here as well in a bit.

For me, I was interested in the connected features of the Juicebox - really haven't noticed a difference in charge time rate between the 30 Amp I was getting and the 32 Amp I'm able to draw from the Juicebox.

2 amps * 240 volts = 480 watts - or a 1/2 kW - so over the course of a hour 30 vs. 32 amps is about 0.5 kWh difference or about 2 miles of range for each hour charging…

2/32 = 6.25% difference

it's mostly noise in the grand scheme of things - some good battery conditioning cycles could easily wipe out the extra 480 watts the charger is providing.

Dave, thank you for the wonderful information in your post. I took delivery of my Bolt yesterday and I'm a big fan of over-engineering things. I put a 100 amp circuit into my garage for my LVL 2 charger .... like you recommended; the future.

I have a curious question about your recommendation on the 20 amp extension cord. I get to plug my Bolt in at work, to a 15amp circuit. I don't need to charge quite frankly though wouldn't say no to it. But for the winter (Wisconsin) I want to precondition the crap out of it. Depending on where I park, I may or may not need an extension cord. So my question; Taking into account how much heavier a 20 amp 25 foot extension cord is and a smidge bulkier, what is the benefit? At first glance, I was thinking more heavy duty but they sell some super heavy duty 15 amp cords too. Would like your insight on this, I'm a few days from buying a cord myself.

The 20mamp recommendation is a hold over from when I mistakenly thought the Bolt would take advantage of charging from a 110 volt 20 amp circuit - it’s an area I forgot to update in the 2018 version- I know for a fact the 2017/2018 Bolt will only charge at 12 amps maximum when charging at 110 volts - so a 20 amp cord is un-necessary for a Bolt - I don’t know if the 2019 Bolt can charge at 16 amps from a 20 amp 110 volt circuit so maybe for that?

But if all you are going to plug into is a normal NEMA 5-15 house hold plug you don’t need the 20 amp cord.

Thank you for the clarification. It's not a bad idea but I'm thinking of the bulkiness first, weight second for my extension cord purchase. The 2019 Bolt is limited to 12 amps when using a 110v hookup. I'm on day 2 of using it myself in that capacity. I hope I will have my LVL 2 hooked up by Tuesday night. The car lets you pick 8 or 12 amps as I believe the earlier years did.

Sorry, one more question. I have read on this forum in numerous spots, not just your post, that the OEM EVSE will operate on 240 volts. I admit that I will never use it as such, but I'm curious how that was discovered? The placard on the OEM-EVSE lists only; '120V, 60 Hz, 12A, AC, 1440W'

Thanks again!

someone opened it and looked at the guts - they were all 240V rated and/or safe. It is apparently the same EVSE as the one delivered in Europe (where 240V is the std), just with different plugs.

I have been using this 50' 12 gauge cord for two months without an issue. Neither the cord nor the connectors get hot and are just barely warm to the touch.

I was motivated to buy the Tesla Gen UMC by this post (rather it''s predecessor) so it seems like a good place to complain. I used it with the Nema 6-20 adapter and a 20ft 12 gauge extension cord. It worked once for an 8hour charge. The next time I tried it, a few months later, it started charging and the gave up after an hour. The UMC no longer lights with any adapter. As it was still under warranty Tesla took it back and promised to send a replacement but they are back ordered because, I suppose, they have to supply one with each Model3 so they have run out for the commoners like me. Others may want to consider my experience with a product that is genius in theory.

Sorry to hear about the failure of your Tesla Gen 2 UMC.

Our Juicebox failed twice in a year, and while they were more than willing to replace it a third time, we opted not to try again. We have been using a Tesla Gen 2 UMC with the 14-50 plug adapter, and Jdapter, as our only EVSE for twenty days now. I've got my fingers and toes crossed. I continue to hear about how the lack of moving parts make EVs so dependable. Just because you can't see the electrons moving, doesn't mean there isn't a lot of hard work going on. These are early days yet.

chargepoint 32A here. Like it a lot, especially the graphs. But, it too failed twice in one year, first time ground fault, second time WiFi. Both times relatively no hassle free replacements including shipping both ways. Great company, I hope I get one to last many years.

There is a surge suppressor at the main panel, and another one at a subpanel that feeds the garage. I don't think it was grid related damage.

Backup L2 is a 20A ClipperCreek, no graphs or WiFi, but bullet proof!

I have the JuiceBox Pro 40, hoping to finish the installation tomorrow night after work. Until then, just plugging into a 110 15A outlet.

I was motivated to buy the Tesla Gen UMC by this post (rather it''s predecessor) so it seems like a good place to complain. I used it with the Nema 6-20 adapter and a 20ft 12 gauge extension cord. It worked once for an 8hour charge. The next time I tried it, a few months later, it started charging and the gave up after an hour. The UMC no longer lights with any adapter. As it was still under warranty Tesla took it back and promised to send a replacement but they are back ordered because, I suppose, they have to supply one with each Model3 so they have run out for the commoners like me. Others may want to consider my experience with a product that is genius in theory.

After complaining to Tesla, I finally received a replacement today. I plugged it into my 14-50 receptacle and watched the green lights, then plugged in my "teslatap" (labelled "Duosida") and plugged it into my Bolt. Charging worked for about one hour and then was interrupted (no idea why, no blackouts, nothing else was affected). Unplugged everything then tried it all again, it charged for a half-hour then was interrupted. The only commonality in the two interruptions was that the failure occurred near the time when charging was due to end (according to the Bolt dashboard), as if the setup cannot deal with the end of the charging sequence. I tried it a third time (when charging was due to end in ten minutes) and it finished without incident. Anyone have any ideas? Don't blame my 240v line which has been working with my Clippercreek for two years without any problems.:(
I read on the Teslatap website (http://www.umc-j1772.com) the following: "Only compatible with some of the new Tesla Model 3 UMC's and you must use only the NEMA 14-50 or 5-15 connector." That may pretty much kill it for me.

this is disturbing news because the Tesla UMC is one of the most affordable/flexible portable EVSE's on the market, but just with the wrong connector :(

My UMC's work fine for my bolt and leaf...I wonder what the problem is.
