Do Chinese EVs charge slower in cold weather?
Updated 2026-05-186 min read
Battery temperature is the biggest determinant of charging speed. Here's how Chinese EVs handle cold weather.
01
The physics
Lithium-ion cells accept full current above ~15°C cell temperature. Below 0°C, current is capped by up to 80% to prevent lithium plating.
02
Preconditioning
Xpeng, Zeekr, NIO and BYD (2026 facelift) support automatic preconditioning when navigating to a DC charger.
This heats the pack to ~25°C during driving to arrive charge-ready.
03
Without preconditioning
At -5°C from cold soak: expect ~40–60% of rated DC peak for the first 10 minutes; full speed after ~15 min of charging warm-up.
Key takeaways
- 01Cold-soaked packs = slower charging.
- 02Preconditioning restores near-full speed.
- 03Use navigation-triggered preconditioning on winter trips.
