This feature matches the battery''s required cooling capacity to reduce heat loss. The system can maintain a 2.5°C temperature difference in the battery cells compared to air-cooled heat dissipation. This lengthens the battery life by two years and increases the discharge capacity by 15% across the entire lifecycle. Growing Battery Storage Demand
Here''s a useful comparison. What you''re reading right now is being written on a MacBook Pro. My laptop''s bottom gets quite toasty when its battery is being charged. The battery pack of last EV I drove, a Leaf e+, stores roughly 1000 times more energy. Batteries and battery packs also heat up when continually discharging at high rates.
