Operating at -40 is one thing, charging at -40 is another.
- 8note 6mo agoi would have imagined that charging at -40 is easier than operating at -40.
- adrian_b 6mo agoI have no idea how true this is, but the press releases claimed that both most of the capacity is retained down to -40 and that the charging speed is proportionally retain down to -40, and that this is the meaning of the operational range.
- nulltrace 6mo agoRight, good to know.
- Dylan16807 6mo agoWhen you're at a charger you can easily spare the 3-4% of battery capacity it takes to heat the pack by 40C. Less if you use a heat pump.
- pjc50 6mo agoHow many people let their ICE engine block get that cold?
- nottorp 6mo agoFor -40, the anecdote for combustion engines used to be that in Siberia you turn on the car's engine in november and off in march. For -20 though, it can happen each year in 4 season temperate climates and north of that.
