Power Battery Seven Common Faults And Treatment Methods

- Jul 23, 2017-

the battery voltage is high: full power after standing, the battery single string or several strings of voltage was significantly higher, other monomer normal.


Failure reasons: ① acquisition error; ② LMU balanced function is poor or failure; ③ low battery capacity, charging voltage rise faster.


Processing method: ① single voltage display value is higher than the other monomer, the actual value of the measured monomer comparison, if the actual value is lower than the display value, and the same with the other monomer voltage, the actual value of the standard LMU The monomer voltage is calibrated; if the measured value matches the displayed value, the discharge of the single cell is carried out manually. ② check the voltage sampling line is broken, virtual access; ③ replacement LMU.
