Does BMS battery management test system have any important functions?

Battery management system BMS is a new product born only in this century. Because the electrochemical reaction is difficult to control, and the performance changes of materials are elusive in this process, such a housekeeper is needed to constantly supervise, adjust and limit the behavior of the battery pack to ensure the safety of use. Its main function is to accurately estimate the state of charge (SOC) of the power battery pack, that is, the remaining capacity of the battery. Ensure that the SOC is maintained in a reasonable range, and prevent the battery from being damaged due to overcharge or overdischarge, so as to predict how much energy or charging state is left in the energy storage battery of the hybrid electric vehicle at any time. In the process of battery charging and discharging, the terminal voltage and temperature, charging and discharging current and total battery voltage of each battery in the power battery pack are collected in real time to prevent the batteries from being overcharged or overdischarged. At the same time, the battery status can be given in time, and the defective battery can be selected, so as to maintain the reliability and efficiency of the whole battery operation and make it possible to realize the remaining power estimation model. In addition, the use history file of each battery should be established to provide data for further optimization and development of new electricity, chargers and motors. It provides a basis for off-line analysis of system faults. That is, the single cells are uniformly charged, so that all the batteries in the battery pack reach a balanced and consistent state. Balance technology is the key technology of battery energy management system being developed internationally. Advanced technology and stable and reliable products will be the core characteristics of BMS products in the future, so what kind of products are advanced technology, stable and reliable products? As the BMS standards of major domestic enterprises are not unified, this paper takes the BMS performance characteristics of Shenzhen Guo Xin Electric Power Company as an example, and expounds them from four dimensions: technology, function, quality and standard specification.
