In city driving in the summer in Phoenix I've seen the range jump by over 50 miles when turning the A/C off.

Anyone see a strange change in lifetime stats? I don't remember exactly what the lifetime stats were before this trip, but I'm sure regen miles were in the ~3500 range and brake score was in the upper 90's. Wh/mi was I think around 260. 9999 regen miles out of 18774 total would be pretty...

If you use the heater, range can be significantly reduced. Driving in strong headwinds, rain, etc. will all reduce range. What do you typically see for Wh/mi ?

12v battery may be going south. It will suck extra juice from the big battery trying to keep it charged until it eventually fails. Rarely have had a 12V battery last more than a couple of years, even in my Escape hybrid.

On the Chevy site, the Bolt is advertised as having a 9 hour full charge time and up to 25 miles per hour charging with the 'available' 240V charger. To keep the price down I imagine a lot of things will be optional, er, I mean available. Still, it will eviscerate a 100 mile FFE in most people's...

Most 240V circuits are designed for higher currents than 120V circuits (think oven, dryer, range, water heater, AC unit.) Usually a 120V circuit is breakered at 15A while a 240V circuit is usually at least 20A but more commonly 30A, 40A, 50A etc.

Is the motor current available as a PID or just the battery current?

I wondered about the RPM. If it is indeed off by two then in your displays the powering motor efficiency would be about 96% and the pure regen braking motor efficiency would be about 76%. Eminently reasonable, I think. Would be interesting to see how high the motor efficiency can be while...

If you have motor torque, current, voltage and RPM PIDs you can calculate motor efficiency? Might be interesting to see how efficient the motor is in both power and regen. A bit confused since in your display showing regen the torque and RPM computes to 4.1kW but volts and amps are 6.2kW?
