Energy Storage BMS Problems and Test Solutions

BMS is the key issue

With the rapid development of electrochemical energy storage, power station safety issues have also become a focus of attention for the whole society. In recent years, global power storage safety accidents have occurred frequently, with a total of more than 80 safety accidents reported, and more than 20 accidents occurred in 2023 alone, which has seriously affected the overall development of the industry.According to statistics, the quality problems of key equipment, systems and integrated installation of power stations are the main reasons for the unplanned shutdown of power stations. Typical risk hazards include long-term inconsistency of battery cells and lack of control measures, battery thermal runaway, communication interruption, PCS cabin temperature is too high, and system waterproofing does not meet standards. Most of these hidden dangers are closely related to BMS.

NGI energy storage BMS test solution protects power stations

BMS has functions such as battery voltage, current, temperature, SOE monitoring, balancing management, and communication control. It can effectively avoid overcharging and over-discharging of batteries, extend the battery life, and is the brain of the battery in the energy storage power station. According to statistics, BMS system abnormality is the main reason for the unplanned shutdown of electrochemical energy storage power stations, and the number of shutdowns accounts for more than 20%. Therefore, BMS is one of the key factors for the safe and reliable operation of power stations.NGI has been rooted in the energy storage industry for many years and has launched the industry-leading power storage BMS test system. It can complete BMS data acquisition (voltage, current, temperature), balancing, energy state estimation, communication, alarm and protection functions.
