Assume this is not going to be your last EV - plan for the future and buy/install a charger only once - at least 40 amps or more and high quality - clipper creek or juice box 40/60 amp charger and you are good to go.

What can I buy to charge the Bolt as fast as possible without having someone wire or reword our home to put in a 240v outlet? Does that even exist? 120v just isn't gonna cut it.

That's exactly why I'm freaking out. I have to charge it for days now.

with 32 amps charge rate (40 amp circuit) the maximum charge time for a Bolt is 9 hours - from zero to full.

--------------------

120 volts * 12 amps = 1,440 watts (plugged into a normal household outlet)

15,000 watt/hours (15 kWh) / 1440 watts = 10.41 (round up to 12) hour charge with the included L1 charger plugged into a normal household outlet

a 24 amp 240 volt charger (30 amp circuit)

24 * 240 = 5,760 watts

15,000 Wh / 5,760 = 2.604 (round up to 3.5) hour charge if you get an L2 charger on a 240 volt circuit

a 32 amp 240 volt charger (40 amp circuit)

32 amp * 240 volts = 7,680 watts

15,000 Wh / 7,680 watts = 1.953 hours (round up to 2.5) hour charge if you get an L2 32 amp charger on a 240 volt circuit.

What would each one of those cost me if our electric company charges us .13111 kwh

If you use 10 kWh it would be $1.31 or about $1.50

Hours of charge don't matter - it's kWH returned to the battery - you are billed by KWh

All of the charge scenarios I laid out lead to the same number of kWh...

Think of kWh hours as gallons of water

Different amp/volt ratings are different amounts of water being deliver...but you still need to fill the bucket to 15 gallons...

A trickle of water will take longer than a gushing hose - but both will deliver 15 gallons - your not billed by how long it takes - you are billed by how many gallons you use.

Household plug = trickle of water to fill the bucket

32 amps @ 240 volts = gushing hose

One fills the 15 kWh bucket faster than the other, but it's the same amount of water/power

Gallons = kWh

$2.00 a day for 50 miles = $0.04/mile

If you drove a gas car @ 28 mpg you would use 1.78 gallons of gas for 50 miles

1.78 gallons of gas at $2.543/gallon = $4.53 - or $0.0906/mile

I'm trying to understand. Is that $2.25 per day or ?Approximately 15 kWh * .1311 = $1.96 - probably about $2.25

If you use 10 kWh it would be $1.31 or about $1.50

I need to know exactly how to go with this option: a 32 amp 240 volt charger (40 amp circuit)Approximately 15 kWh * .1311 = $1.96 - probably about $2.25

Or am I safe to go with this one:

a 24 amp 240 volt charger (30 amp circuit)

I drive approx 10k miles per year.

If the cost difference is minimal get the 40 amp one.

Could you help me understand exactly what I need to buy other than the 240v outlet that needs to get installed. Are there any other faster charging options?40 amp circuit charger can fill the Bolt from zero to full in about 9 hours

2500 kWh @ .1311 kWh = $327.75 in electrical charges - add 10% for charging lost so about $360 in electricity/year

2500 kWh = 2,500,000 watts/year for 10,000 miles

2,500,000 watts at 32 amp charge rate means you'll spend approximately 325.52 hours charging the car across the course of the year - probably more like 360 hours given charging loss

2,500,000 watts at 24 amp charge rate means you'll spend approximately 434.02 hours charging the car across the course of the year - probably more like 480 hours given charging loss

360 hours = 15 days of charging

480 hours = 20 days of charging

360 hours of charging per year = about .98 hours day on average

480 hours of charging per year = about 1.315 hours day on average

you need to have a licensed and professional electrician install a 240 Volt 40 amp circuit (or 30 amp circuit your choice)Could you help me understand exactly what I need to buy other than the 240v outlet that needs to get installed. Are there any other faster charging options?

after they install the circuit which will require a permit, wire and some electrical junction boxes you need to purchase a 240 volt car charger

here are several choices for car chargers:

https://emotorwerks.com/store/residential/juicebox-pro-40-smart-40-amp-evse-with-24-foot-cable

https://www.chargepoint.com/products/home/order/

the electrician will install the charger using the circuit you had them install - the electrician has to have the wire/breaker/charger all match

if you buy a 40 amp charging unit - the electrician will need to install a 40 amp circuit

if you buy a 32 amp charging unit - the electrician will need to install a 32 amp circuit

the electrician will have pull wire from your electrical box to where you plan to park you car overnight to charge it

the father away your main electrical box is from your garage - the more this will cost due to the cost of wire.

you will need to get a bid from an electrician on the cost to add a new 240 volt circuit to your existing electrical system, pull wire, install a junction box, and then wire the car charger to the new circuit.

Luckily I haven't picked up the car yet. A few bids came in at $1,300-$1750. Wow! Plus the cost of the charger.you need to have a licensed and professional electrician install a 240 Volt 40 amp circuit (or 30 amp circuit your choice)

On top of that here's what I am uncertain about. 1. This is a first year Bolt EV, it doesn't have proven long term reliability. 2. If parts will be easily available for it. 3. If I get hit how safe is it in each angle.

no there is nothing you can do without installing a 240 volt circuit - unless you want to use public chargers close to work or house.Could you help me understand exactly what I need to buy other than the 240v outlet that needs to get installed. Are there any other faster charging options?

there are two types of chargers

L2 chargers - typically 208 volts @ 30 amps

DCFast charger - 400 volts/150 amps - these are commercial installs typically at strip malls, car dealers, and other useful road tripping locations.

DCFast chargers will charge the car from zero to full in about 1 to 1.5 hours - but you would have to park next to a DCFast charger

L2 chargers (like charge point or blink) will take over 12 hours to fully charge the bolt.

The best solution is to charge at home, which requires you to install a new 240 volt circuit.

you have three choices:

1. install a new 240 Volt circuit at your home so you can charge over night

2. use the charger that comes with the car and suffer the long duration charge sessions

3. use public charging infrastructure near your home or work to charge the car (L2 or DCFAst)

you can use the app plug-share to look for chargers near your home/work locations - most public chargers will take a couple of hours to charge the Bolt for daily use, or several hours (10-12) to charge the Bolt if it's close to empty.

I would suggest you cancel your order - it seems to me the Bolt isn't the right car for you.
