Discontinue use.

A bulging lithium battery pack may catch fire and explode, so be sure to stop using it. The swelling of lithium batteries is caused by overcharging during charging. The internal chemical properties of the battery change and gas is produced. Generally, polymer soft-pack batteries will bulge when overcharged.

Chaowei lithium-ion power battery adopts high-energy aluminum-plastic film flexible packaging, and the energy density of lithium-ion battery is as high as 188Wh/kg. At the same time, combined with the lightweight mechanism design, it effectively improves the vehicle's cruising range.
