The battery heating system prevents the lithium-ion battery from overcooling in winter, enabling efficient battery use. For example, the battery applied to Hyundai Kona EV increases the fast charging time to about 3 hours when the temperature drops to -10℃, but it can be shortened to about 1 hour and 40 minutes by applying a heating system.

Battery warmer and pack heater for electric vehicles capable of charging from 10% to 80% of battery capacity within 18 minutes at 350kw super fast charging.
