"Free" heat in cabin

Apologies if this has been covered before, but is it true there is a way to bleed off the small amount of heat from the battery/electronics into the cabin without using the resistive heater? Is it enough to keep the screen free of condensation on the inside when it's about 40-50F ambient?

Re: 2017 Bolt 8 vs 12 amp charge

..........as it keeps the battery less-cold...........

Not always good, to a degree (no pun intended) charged batteries will store better 'cold' although that has to be weighed against sluggish performance when you want to actually use and discharge them.

Re: "Auto" HVAC questions

Seems those expensive, failure-prone, rattling, leaking, headroom-stealing abortions must be quite popular after all, or all those car makers could be wrong. To get back to the subject of the topic, ventilation is necessary and if there is no 'automatic' ram airflow effect then something else will b...

Re: "Auto" HVAC questions

Sunroofs are not compulsory on any vehicle and you always have the freedom to say no to them (unless perhaps you are buying used). They are just a way of improving ventilation, how they are installed and their reliability is another consideration. Oh, and of course, you have the freedom to express y...

Re: "Auto" HVAC questions

Too bad there is no sunroof option - a tilted sunroof is a good way to extract warm and/or humid air from the cabin without using fans or a/c and only adds minimal drag.

Cars these days are becoming like houses - fully sealed and then needing "air management"

Re: Regen question

I too was skeptical about L, but have adapted to it and I now prefer the way I get "instant" slowdown with using one pedal. Correct me if I'm wrong, but there must be a time delay between "power on" and "braking" when using two pedals, unless you're a rally car driver a...

YAMMV - Close call

We are a couple of old retired duffers, so our usage pattern is overwhelmingly urban and typically no more than 30 miles a day (i.e. boring and pottering), but today we did a freeway run (Orcutt to SBA airport, hwy 101) that was almost exclusively at 67mph, set on the cruise control. We set off at 1...

Re: parking in the sun

Sun is bad for any vehicle at least in terms of UV degrading the paint and interior surfaces. In summer you will place a higher load on the A/C after parking in the sun, and you may also heat the battery a bit but not much as it is low to the ground. Note on a windy day it is probably better to park...

Re: Charge: As soon as possible, or as late as possible?

FWIW I'm an electrochemist who spent (or wasted) over 40 years trying to make electrons swim. In the 1970's we found users of nickel-cadmium batteries in walkie-talkies got much better life when the devices were being heavily used (and abused) as opposed to spending all their lives on "float&qu...

EVSE supply voltage

Has anyone investigated how "pure" the AC supply to the GM included EVSE must be? Will it tolerate an inverter power supply, there seem to be large variations in the sine wave outputs of these devices? I am thinking in an emergency ONLY to run a "normal" IC car with an inverter s...
