In the future, electric vehicles will use lithium batteries as their main power source. The main reason is that lithium batteries have the advantage of high energy density, so their performance is relatively stable. However, the quality of lithium batteries is not easy to control when mass-produced. There are slight differences in battery power when the battery cells leave the factory. With the operating environment, aging and other factors, the inconsistency between batteries will become more and more obvious, and the battery efficiency and lifespan will also become worse. In addition, overcharging or over-discharging may lead to safety issues such as fire and combustion in severe cases.
The importance of the battery management system BMS is self-evident. BMS is the core technology of the power battery pack and is also the link that vehicle companies pay most attention to.
1. Technology and trends
BMS is part of the battery pack. The battery pack is the core energy source of new energy vehicles and provides driving power for the entire vehicle. It mainly forms the main body of the battery pack through a metal shell envelope. The modular structural design realizes the integration of battery cells, and the thermal management performance of the battery pack is optimized through thermal management design and simulation. The electrical components and wiring harness realize the safety protection and connection path of the battery by the control system; the management of battery cells is realized through BMS. , as well as communication and information exchange with the entire vehicle.
The main functions of BMS include: estimating the state of charge of the battery, detecting the usage status of the battery, and controlling the cycle life of the battery. During the charging process, it manages the heat of the battery, starts and stops the cooling system of the lithium battery, and also manages the balance between the individual batteries to prevent danger caused by overcharge and overdischarge of the individual batteries. In addition, the healthy working status of the entire battery is monitored.
