4 Series BMS Test Equipment Multi - String Protection Board Tester Scan Start
1. Test The Type Of Protective Board
1) Negative electrode plate charge and discharge in the same port / negative electrode
2) Negative electrode plate charge and discharge split port / negative electrode
3) Positive electrode plate charge and discharge in the same port / negative electrode
Note If you have the above type of protection board , you can communicate with our company
2. Special Test Items
1) Short - circuit protection test ( subtle level )
2) Single section self - consumption test ( means true and accurate self - consumption for each section )
