Cool new things you found out

Tue Feb 07, 2017 1:24 pm

Maybe it was in the manual in bold.
Maybe it was in the fine print.
Maybe it wasn't.

Please use this thread to post cool (or maybe frequently overlooked) things you found out about your Bolt.
Features.
Tips.
Tricks.

I just found out I can cancel creep in D with one click of the paddle for Regen on Demand on at a stop. This also evokes hill assist / hill hold.

GM has stated on the record that the maximum fast charge rate is 60 kw. Not the frequently speculated 80 kw.
But hey, less of a bummer now that most infrastructure at the moment maxes out at 50 kw DCFC.

The DC/DC converter for the 13.5 volts is rated at 1600 watts. (1.6 kw) (about 120 amps)
Keep that in mind you after market stereo buffs. The 12 v battery will provide more..... for a short time (30-60 minutes).

I heard in European press reviews the Bolt described as a 160 kw car. (which would be 214 horsepower)
All U.S. press releases call the Bolt a 150 kw car. (200 horsepower)
I have resolved the discrepancy.
The motor is rated at 150 kw.
The battery is rated at 160 kw, meaning you can run 10 kw of accessories while having your foot on the floor.

What power input do you think the motor needs in order to create 150kW output? What do you think are the conversion losses between the DC battery and AC motor?

I just learned the Bolt EV DOES use waste heat from the electronics to gently heat the cabin.

With heat / ac button always off.... after a few minutes of drive, I can get a 20 degree (at least) raise in temperature out of the vents. Kw draw is the usual 0.5 kw at stops in day (headlamps off) and 1 kw at night.

With resistive heater off, a 20 - 30 degree rise in temperature is perfect for most Californians.

GOOD JOB CHEVY! Another pleasant surprise!

Well yeah, I agree. But what about if it's hot outside?

Please post information about charging at 60kw not 80kw. Since the manual states 80kw. Was that a misprint?? And the 20-30 articles about the charging are wrong?? Please provide proof.

A/C uses much less power than resistance heat, because it's only moving heat, not "making" it.

You are correct - I was looking at pre-ship information from Electrek.com Apparently the DC charge spec has been increased to 80kW, as there was also one Chevy presentation that said 50kW.
Even at 80kW it will still take an hour or more, rather than than a half-hour, for 200 miles.

That's not what I was referring to. If the car's electronics produce heat that is then pumped back into the cabin, that means the air conditioning will work even harder.

Still, it's a nice feature.

We should remain skeptical because the manual states that 80kW is needed to recharge 90 miles in 30 minutes. However, that recharge rate has already been demonstrated with a 50kW (125A) charger.
