Protection Board Tester PCM BMS Lithium Battery Detection Lithium Battery Protection Board
BMS Tester Features
1. Support two detection modes (full channel automatic scanning detection mode, single channel independent trigger detection mode)
2. Support 30 channels to simulate battery voltage output, and can simulate charging overvoltage and discharging undervoltage for any channel at the same time
3. Support user-defined test of intelligent protection board, RS485 control
4. Support discharge overcurrent VDOC voltage simulation test, RS485 control
5. The number of test strings, the number of test boards, and various protection parameters can be set arbitrarily, and automatically saved in the system's internal memory EEPROM
6. Provide 4 RS485 communication output interfaces and 12V power supply output, which can directly communicate with external display screens, system expansion boards, etc.
7. Built-in safety alarm buzzer, which provides buzzer when the system is connected, key action, and channel test is completed
BMS Tester Description
It is a new type of high-speed lithium battery protection board (BMS) tester, which supports simultaneous testing of 4 to 8 battery protection boards, and can perform fast function detection on up to 30 channels. The main functions of the detection include channel leakage current, channel equalization current, charge and discharge Power MOSFET on-resistance, battery cell channel overvoltage protection and release function, battery cell channel undervoltage protection and release function, and protection delay time function.
