Hello ,
First off I’m a new user and I have searched the forum for answers but can’t find what I’m looking for. I’m sorry In advance if I posted something that’s already posted.

I currently rent and live in a basement suite. My Lanlord’s have no issue with me plugging in to the regular 110v outlet. They were asking me if there was a way I could see how much energy I’m going to be using in each charge. Does the Bolt show this information in the Infotainment Menu somewhere?
Any help would be greatly appreciated.
I pick up my Bolt on Saturday from the Dealership 😊

It's possible to meter it. The problem though is that meters like a Kill-a-Watt tend to fail under extended use at high power.
The car does not have a metering system for each charge.

Better is to estimate using time and cost of power. Charging 12A at 120V is 1.44kW. To get the number of kWh multiply that rate by the number of hours. For example, just to keep it simple, say the charging window is 10 hours. In that 10 hour period 14.4 kWh would be delivered.

Now take that energy and determine the cost. For example, a summer kWh for me is about 12 cents total. So, in that 10 hour power the 14.4 kWh * $0.12 is $1.73. Over the course of a month that's about $52.

Now this example is far from perfect. That 14.4 kwh gives close to 60 miles of range per day (56.2 to be precise at that Bolt's stated efficiency of 3.9 miles/kWh). So, if you average mileage is half that per day, then you're over by double.

So, that leads to likely the best estimator: convert miles per month into cost. Using the numbers above it's possible to determine that the cost per mile driven is $1.73/56.2 which is a shade over 3 cents a mile. So, you can simply record the mileage for a month, multiply that by 3 cents, and pay that. So, if you go 850 miles in a month, pay 850 * 0.03 = $25.50 for the month. If it were me I'd round it up to $30 just to thank the landlord for facilitating charging my Bolt.

Hope this gives you some insight. I strongly suggest not trying to be a stickler to the penny. If you show your landlord some rough estimates, then offer to pay something reasonable in the ballpark of those estimates, you should be able to get this thing done.

Sort of. The Bolt will show you how much energy you've used driving since the last "full" charge (where "full" means whatever you set for the target charge level, assuming you have a 2019-22 model).

So it won't show you how much energy you receive from the wall, but if you charge all the way to your target, you can assume that it's roughly the amount you used since the last charge.

WoW I really appreciate this response. I’m in Canada so will have to do some converting. What if use charge stations in between? Will that throw off the total km per month calculation?
Im the newest of newbies with this stuff. I have told my Lanlords I would definitely pay whatever needs to be paid. They just want to see some numbers.
I think if I use that math you suggested : 1.144kW x by the hours plugged in.
I need to find out how much a kWh is in BC Canada.
Am I on the right track?
I wish there was an app for this lol.
thank you for all you help

It will be very difficult to do with the stock EVSE (charger). Some EVSEs will display how much energy has been dispensed, or will provide this info through an app. My home charger does not, but my portable (Shell Recharge) does display kWh usage. You could make up a meter/display for under $50 using something like this: Amazon - AC Current Voltage Amperage Power Energy Panel Meter LCD Digital Display Ammeter Voltmeter Multimeter with Split Core Current Transformer CT AC 80-260V 100A Multi-Function Power Monitor

Always say how many miles you drive.

Yes, an infotainment option is to show energy pop-up when you power off car. It is in the Green energy screen all the time too.

My hot weather drive of 60 miles mixed highway/city hills requires about 13.8Kwh a night to replace it. If you drive more or less then compute off that. Winter can double amount.
The EPA reference is like $550 a year but my rate is less.

Weather, elevation, driving style and other factors could affect your mpg-e. The rated city and highway numbers can be found for reference. The window sticker has some odd other way to measure like hundred miles or such.

Expected miles each day???/

There are millions of simple calculators online. Electric car charging cost and time calculator

USA electric is usually 120VAC so 120 x 12 = 1440. In reality there will be circuit and charging losses.

You need to be sure your (rental) circuit can handle 12A "continuous" current. It is like running a toaster or hair dryer for 10 or more hours on the circuit.

WoW I really appreciate this response. I’m in Canada so will have to do some converting. What if use charge stations in between? Will that throw off the total km per month calculation?

The metric unit of conversion typically is kWh/100km. Here's a thread on the subject:

Miles per KWh in US and KWh per 100Km in Canada

I looked for a way to compare American’s “miles per KWh” and the Canadian “KWh per 100Km” but had no success. Anyone have a formula or comparative chart?

www.chevybolt.org

Yes charge stations in between will throw off the calculation. Whether or not it's important depends on the ratio of charging at home vs. charging out in the wild. If it's occasional, then just treat it as noise. It's a bit of a different conversation if you are charging away from home all the time.

Shows the average to be about 12.6 cents per kwh. You can just ask your landlord for an electric bill. It'll have the rate posted on it.

Don't overthink it. Get a ballpark number and round up a bit, then call it a day.

P.S. to answer your question in your other thread, don't bother buying a new EVSE because of length. Get a 12 gauge extension cord that gives you the length you need to get to the EV. The gauge is important, so don't just use any old household extension cord.

The car has a trip odometer that you can reset, which also shows the average elec usage over that distance. The product of these numbers is the kWh used since the odo was set. You could take a picture and reset it once per month, and attach with payment. It will probably run about $20/mo.

After a few months, you can probably negotiate a fixed amount to add to your rent.

You should bump this number by 10% if you are charging at 240V, and 20% at 120V, to account for charging efficiency.

There's no "conversion" needed, kWh and hours are the same in Canada and the US.

Here in BC electricity is around $0.12/kWh plus some fixed-cost delivery and other miscellaneous charges. To be on good terms with your landlord, I'd just be generous and round up to $0.15/kWh.

If it was me and the landlord was amenable to it, I'd forget about all the details and just come up with a flat fee based on my average monthly mileage. For example, if you typically drive 2,000 km /month then at the EPA rated ~16kWh/100km you'd be using around 320 kWh because (2000/100) X 16 = 320. 320kWh at $0.15/kWh = $50 - so offer to pay an extra $50/month and call it even.

And just remember that at current prices in BC ($2.15/ℓ ) $50 would buy you around 24 litres of gas, which at 7ℓ /100km would only get you as far as 350 km....

I like the Eyedro system, it works quite well, just clip onto the feed wires in the panel.
Edit: Your landlord can install and charge you based on the KWh your car takes.

There really isn't a reason to scream is there?

I would not advise using these cheap devices for an EVSE. It's not clear they are designed to handle the high electrical load for the extended times that a L1 EVSE is going to run.

It is my understanding the BOLT maximum absorption rate is 7.6 KW/hr for the purpose of protecting the 400-volt battery. Is this true?

 

[MichBolt]

It is my understanding the BOLT maximum absorption rate is 7.6 KW/hr for the purpose of protecting the 400-volt battery. Is this true?

Sort of? On 2017-2021 Bolts, the Level 2 charging is limited to 7.6 kW because that's what the design of the on-board charger and wire harnesses are limited to (32 amps). The battery itself is capable of being charged at up to 55 kW (150 amps) using DCFC.

For the 2022 model, the Level 2 on-board charger and wiring has been upgraded to handle 11.5 kW (48 amps).

 

[NortonCommando]

It is my understanding the BOLT maximum absorption rate is 7.6 KW/hr for the purpose of protecting the 400-volt battery. Is this true?

Nope.
Have you heard of DCFC?
The Bolt can handle 50-52 kW of power from a DCFC station.

Back to the OP: What about plugging a simple 'kill-a-watt' meter into the outlet before the extension cord and measure a few charges to get a base line of kWh usage vs miles driven that day.
If you are worried about using it, also buy a cheapo IR temp reader and measure the heat build up at each connection in this system to the EVSE (charger).

These temp readers can also be used around the kitchen and to prove you don't get any advantage driving in L.
(Point it at your brake discs after a drive.)
