Battery management system for HEV/ BEV/ backup power supply

الوصف

EK-FT series mainly used in Hybrid Electric Vehicle (HEV for short), Battery Electric Vehicle (BEV for short) and energy storage backup power supply.
In order to satisfy the large scale vehicle and energy storage power requirement of high voltage and high capacity, the design of EK-FT series is with good scalability. Detecting the max voltage from dozens volt Ah to kilovolt and detecting the max current from dozens Ah to thousands of Ah through serial and parallel extension to satisfy customer's individual requirements. In order to shield electromagnetic interference (EMI for short) on Hybrid Electric Vehicle, BMS rationally isolates high voltage control and weak voltage detection etc.
The components of EK-FT series have reached auto level processing chip. Supporting CAN, RS **5 and other kinds of communicate protocol. Significant improvement on safety, reliability, efficiency after adopting high redundancy design for electrociruit.
