The main functions of the heating film for new energy vehicles include the following:
1. Preheating of batteries in low-temperature environments during winter: When new energy vehicles are parked for a long time or started in low-temperature environments, the heating film quickly raises the internal temperature of the battery by energizing it, restoring it to the normal operating temperature range, thereby shortening the battery charging and discharging time and improving battery performance.
2. Battery thermal management: During the battery charging and discharging process, the heating film can work in conjunction with other thermal management components to ensure uniform temperature distribution inside the battery, avoid local overheating or undercooling, and thus improve battery life and safety.
3. Technical advantages: The heating film adopts advanced heating technology, which can achieve fast and uniform heating, and the speed of increasing battery temperature far exceeds traditional heating methods; At the same time, the heating film only needs to use the battery's own electrical energy for heating during the heating process, without the need for additional energy, which reduces energy consumption and emissions; The heating film also has good thermal stability and safety, and can maintain normal operation in harsh environments such as high temperature and high pressure, ensuring the safe operation of the battery.
