Zhejiang Bangzhao Electric Co., Ltd. Energy Storage Systems For Pipe Welding Machines includes lithium iron phosphate battery module, BMS, solar controller, AC-DC charger,Pure sine wave inverter, central control unit CCU, temperature detector, integrated structure, etc.

Features:

1. All-in-one design, high integration and space saving installation;

2. Using high-performance lithium iron phosphate cells, laser welding, good cell consistency, designed service life of more than 10 years;

3. Charging and discharging are controlled separately, which is convenient and reliable to control charging and discharging. The discharge port will not be disconnected when over-charging, and the charging port will not be disconnected when over-discharging, the system has good stability;

4. Master-slave mode, passive equalization, can manage the equalization resistance, can set the equalization start voltage difference, and monitor the equalization resistance temperature, more intelligent and safe, and reduce the impact of barrel effect on system energy storage;

5. BMS adopts NXP(USA) automotive-grade high-performance chips, with strong anti-interference, good reliability and wide temperature range;

6. CAN2.0 communication interface, has the advantages of strong real-time performance, long transmission distance, strong anti-
