Due to the uneven performance of each unit battery in naval power batteries, when one battery in the battery pack overheats and burns, it will ignite the entire battery pack. Use power battery E series polyimide foam products to separate each battery unit. When a battery burns, the adjacent battery will not explode due to excessive temperature to avoid major accidents.
In addition, in extremely cold areas, due to the low temperature, the battery discharge is not sufficient or cannot be discharged. The power battery E series polyimide foam product is used to insulate the battery to ensure that the power battery has a relatively high discharge capacity and ensure the normal operation of the electric vehicle.
