Battery Management System (BMS) is an electronic control circuit that can monitor and adjust the charging and discharging of batteries, and adjust the entire system. With the increasing popularity of high-power density lithium batteries in daily life, the accompanying lithium battery management system technology BMS has also emerged. BMS is used to control the charging and discharging situation of lithium batteries, control the operation of the charging and discharging circuit under appropriate conditions, and timely cut off the path of the lithium battery when it faces loss of control, ensuring the safety of the battery.

Hongmei has developed excellent products with good resistance to current shocks to meet the safety and reliability requirements of battery management systems. This can fully ensure the safety of personnel around the controlled battery, greatly improve application reliability, and ensure the normal operation of the entire battery management system. For example, the Super Trench MOSFET series products adopt a shielded gate deep groove technology with charge balance function, which reduces the characteristic conduction resistance (Rsp) and gate charge (Qg) of the device, comprehensively improves the temperature characteristics of the product's conduction resistance, effectively controls the amplitude of the device's conduction resistance increasing with temperature, and significantly enhances the current capacity and impact resistance of the device at high temperatures. The product will be more suitable for applications in high-temperature and harsh environments.
