EVs have a high voltage battery pack that runs the motor, air conditioning compressor, and other high drain accessories. It also runs a DC-DC converter that creates 12V from the 400V-800V main battery pack to run accessories such as the computer electronics, windshield wipers, lights, power windows, etc.
EVs also have a small 12V battery to provide power to these low voltage circuits, especially the computers, so you can get the EV 'turned on' and activate the high voltage battery pack.
In most EVs this 12V battery is a traditional lead-acid battery, and if it goes dead then the entire vehicle is dead, even if the main battery pack is 100% charged. Once the main high voltage battery pack is energized (car turned on,) then the DC-DC converter recharges this accessory battery.
Tesla has been replacing this 12V lead-acid accessory battery with a 12V Lithium battery to save weight and space.
This dufus EV owner removed this accessory 12V lithium battery from his car and tried to recharge it using a standard 12V car battery charger, which would fry ANY lithium battery.
We now return you to your regular EV bashing...
That's the part that eluded me.
I wondered, "who picks up something as big and hard-to-handle as an EV battery and drags it into his house?"
Very clear analysis.
Too bad the reporter didn’t bother to do your research
