Re: [EVDL] Charging a BOLT from 120v
While there isn't a specific setting for that, you can get the same effect. Newer bolts allow you to set a maximum SOC level, most folks set this to 80-90% of full, when the vehicle gets to that level it stops charging. While I haven't tried it, I believe you can adjust that all the way down to 50% or perhaps lower. So if you son arrived with say 60% of full capacity, and set the max charge level to less than 60%, it wouldn't charge but would still run the battery heater/etc. as needed It would be a bit of a pain, since he'd need to set it back to 80-90% when he got home, but it's doable. If he's a hacker, there are a few folks working on reverse engineering the canbus codes, so you could set up an Arduino/ESP/etc. with a canbus interface and perhaps GPS and have it automatically change maximum charge levels based on location. Without a GPS you could setup a button to tell it when he's at work, or if you use an ESP32/ESP8266 it could be setup to scan for WiFi access points that might only be available near work and determine location that way. Of course the best option might be to discuss paying for charging with the Boss, point out that it will draw less than 1.5kw when plugged into 120V and maybe pay a flat rate per month for charging.

Re: [EVDL] Charging a BOLT from 120v
> That's crazy expensive Check your math. its a great deal. About $15 per month for 20 days of work place charging or about 75 cents a day. Spread over 7.5 hours a day, that is about 10 cents an hour. To charge from an L1 charger takes 1.5 kW per hour, so the price is about 6 cents per kWh much below the typical 12 Cents national electric rates.

Re: [EVDL] Charging a BOLT from 120v
That's crazy expensive, at about $1.30/kwh if you charge for 8 hours full bore. How about negociating a price more like $30 / month, which is about 22 days x 8 hours x $0.15 / kwh Peri << Annoyed by leaf blowers ? https://quietcleanseattle.org/ >> -- Original Message -- From: "Robert Bruninga via EV" To: "Electric Vehicle Discussion List" Cc: "Robert Bruninga" Sent: 13-Sep-21 11:25:48 Subject: Re: [EVDL] Charging a BOLT from 120v Its an easy problem to solve.

Charging usually does take more current than a block heater does. However, that restriction sounds more like a political move on the employer's part. Conversions have used waterbed heaters and plant soil heaters to keep their lead batteries warm. Could he fix something like that to the underside of the battery tray? Fair's fair; if the other employees can keep their engines warm, he ought to be able to keep his battery warm.
