A Battery Management System (BMS) is crucial to the safety, efficiency, and service life of battery energy storage systems. It continuously monitors key parameters such as voltage, temperature, current, and insulation resistance. To effectively perform its control and protection functions-particularly in managing charge and discharge cycles and interfacing with the Power Conversion System (PCS)-the BMS relies on advanced power electronics. Therefore, IGBT chips play an essential role in its operation.
IGBTs: Core Components for Efficient Power Control
IGBTs are fundamental components in energy conversion and transmission. Their use in power conversion significantly enhances efficiency and power quality, offering both energy-saving and environmental benefits. In BMS-based energy storage systems, IGBTs-through precise control of electrical energy-directly influence charge/discharge efficiency, response speed, and overall energy consumption, making them essential to improving system performance.
How to Select IGBT Chips for BMSs
IGBT chips have undergone multiple technological iterations, evolving from PT and NPT technologies to the latest FS generation. These advancements have led to thinner chips, lower thermal resistance, and improved junction temperature (Tj) characteristics. The introduction of IEGT, CSTBT, and MPT technologies has further reduced the Vce(sat) coefficient and increased power density. Optimization of surface metal and passivation layers ensures that BMS reliability requirements are fully met.
