What is in car energy storage

　　With the popularity of electric vehicles, in vehicle energy storage power systems are receiving increasing attention. The onboard energy storage power system refers to the power system installed on electric vehicles, used to store electrical energy and supply it for vehicle use. It can not only provide continuous power supply for vehicles, but also improve energy efficiency by recovering vehicle braking energy. This article will provide a detailed introduction to the structure, working principle, performance characteristics, and application scenarios of the vehicle mounted energy storage power supply system.

　　1、 Structure of on-board energy storage power supply system

　　The onboard energy storage power system mainly consists of battery pack, battery management system, charger, energy recovery system, etc. Among them, the battery pack is the core part of the entire power system, which is used to store and release electrical energy. The battery management system monitors, protects, and manages the battery pack to ensure its normal operation and safe operation. The charger provides charging power for the battery pack and controls the charging process. The energy recovery system converts braking energy into electrical energy and stores it in the battery pack during vehicle braking.

　　2、 Working principle of on-board energy storage power supply system

　　The working principle of the on-board energy storage power supply system mainly includes the charging process and the discharging process. During the charging process, AC power is converted into DC power through a charger and stored in the battery pack. During the discharge process, the battery pack provides electrical energy to the vehicle, and the braking energy of the vehicle can also be converted into electrical energy through the energy recovery system and stored in the battery pack.
