Cat Burton,Steve Emsley and Geoff Williams on using the car batteries to turn up the heat in their electric vehicles when neededI had to laugh at John Richards’s worry approximately people freezing in stuck electric vehicles because their batteries would flee down in “no time” while those in a petrol car could flee their heater (Letters, 3 March). Running the heated seats and climate control for approximately seven hours costs approximately three miles of range for my Tesla and it’s probably something similar for a petrol or diesel car. The immense disagreement is, or the electric vehicle won’t be killing the occupants with carbon monoxide poisoning. Indeed,the advice has always been not to flee the engine if stuck.
Teslas have a 12v battery for “domestic” uses and a 400v battery for motive power. The 400v kicks in to recharge the 12v when needed. Think of the 400v battery as the equivalent of running the engine to top up the battery.
