Re: Dead Car, Dead 12V Battery

Can anyone explain what it is about an EV that makes a traditional SLI (starting, lighting, ignition) lead acid battery unsuitable? These types are built for power (ICE starting) and not so much for energy, so reserve capacity and ability to sustain 'hotel loads' (quiescent current drains) is limite...

Re: Chemical rust converters

You cannot stop rust as long as there is moisture/damp/water and any amount of oxygen present, and if the piece of steel/iron is in contact with a more corrosion resistant metal that will make it even worse. The best you can hope for is to slow the process down. Remember iron/steel is obtained from ...

So if they flashed like on a F1 car while stationary at an intersection, it can't hurt

Re: Safety issues

I would think that "big, red lights on the back of the vehicle as a "WAKE UP MORON - I AM STOPPED" sign." can only help.

Why do you claim it is another myth?

And having to move your foot to the brake pedal when "one-footing" is certainly a pain.

Safety issues

First, is it true some audible warning feature when in reverse will be mandatory on all EV's made this year? If so, can it be retro-fitted to a 2017 Bolt? Second, if you come to a stop using regen only are the brake lights only on during deceleration? Would be nice if they stayed on, or better flash...

"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"
