What are the functions of lithium battery BMS?

Lithium battery BMS function analysis 1. Battery protection, similar to PCM, overcharge, overdischarge, overtemperature, overcurrent, and short circuit protection. 2. Energy balance, the entire lithium battery pack, because many batteries are connected in series, after working for a certain period of time, due to the inconsistency of the battery cell itself, the inconsistency of the working temperature and other reasons, it will finally show a big difference. It has a huge impact on the life of the battery and the use of the system. Energy balance is to make up for the differences between individual battery cells to do some active or passive charge or discharge management to ensure the consistency of the lithium battery and extend the life of the battery. 3. SOC calculation, the calculation of the power of the lithium battery is a very important part of the BMS, and many systems need to know the remaining power more accurately. Due to the development of technology, there are many methods accumulated in the calculation of SOC, and the remaining power can be judged according to the battery voltage if the accuracy is not required. In general: Lithium battery BMS is a layered, graded and unified management of single batteries, battery packs, and battery stacks, and various parameters of batteries (single, group, stack) are adjusted according to the characteristics of each layer and each level. Calculate and analyze the operating status to achieve effective management of equalization, alarm, protection, etc., so that each group of batteries can achieve equal output, and ensure that the system achieves the best operating status and the longest operating time. The above are the types of batteries and lithium battery BMS functions. The lithium battery management system BMS serves as a strong guarantee for the safe use of batteries, making the batteries always in a safe and controllable charge and discharge process, greatly improving the cycle of the battery in actual use.
