A Battery Management System (BMS) is a crucial component in modern energy storage systems, ensuring the safe and efficient operation of rechargeable batteries, particularly in electric vehicles (EVs), energy grids, and consumer electronics. The BMS continuously monitors key parameters like voltage, current, temperature, and state of charge (SoC) to ensure the battery operates within safe limits. This helps prevent dangerous conditions such as overcharging, over-discharging, and thermal runaway, which could lead to battery failure or hazardous situations. Additionally, the BMS manages the overall performance by balancing the cells in the battery pack, ensuring uniform charging and discharging to extend battery life and maximize efficiency.
Beyond protection, a BMS also provides real-time data and diagnostics, making it an integral part of any battery-powered system. In electric vehicles, for example, the BMS communicates with the vehicle control unit (VCU) to provide critical information about battery health and performance, such as the state of health (SoH) and energy usage patterns. This information not only optimizes battery usage but also contributes to the overall efficiency of the system. Whether for EVs, renewable energy storage, or portable electronics, a well-designed BMS is key to maintaining safety, reliability, and optimal performance.
Our Automotive 72V Integrated Battery Management System (BMS) is designed for high-performance lithium-ion battery systems, offering support for up to 24 channels (using 2 Analog Front Ends) or 18 channels (using 1 AFE). Built for robust automotive applications, it operates efficiently across a wide temperature range from -40°C to 105°C and can handle a maximum discharge current of 100A. This makes it ideal for battery systems with capacities between 25Ah and 35Ah, ensuring reliability and safety in demanding environments.
The BMS provides comprehensive data acquisition, monitoring cell voltage, current, and temperature while offering key safety features like overvoltage, undervoltage, over-temperature, under-temperature, and overcurrent protection. It includes advanced protections such as fuse blow detection, isolation monitoring, and HVIL. With highly accurate algorithms for State of Charge (SOC) and State of Power (SOP) at 98%, and State of Health (SOH) at 95%, the system ensures optimal battery performance and longevity. Supporting various battery chemistries, including Li-ion, NMH, and lead-acid, it meets ASIL B automotive safety standards.
