1. Fault original: 1 collection error; 2LMU balance function difference or failure; 3 battery capacity is low, the voltage rises faster when charging. Workaround: 1 The monomer voltage display value is higher than the remaining monomer, the actual voltage value of the monomer is compared.

If the actual value is lower than the display value, and the actual value is standard to LMU with the actual value of the actual value. The monomer voltage is calibrated; if the measured value is consistent with the display value, the artificial power lithium ion battery is discharged. 2 Check the voltage sampling line is not broken, false; 3 replacement LMU.

2, the power lithium-ion battery voltage is low: after the full power is allowed, the power lithium ion battery single or several monomer voltage is clear, and other monomers are normal. Failure Original: 1 collection error; 2LMU balance function difference or failure; 3 battery self-discharge rate; low battery capacity, voltage drop in voltage is faster. Solution: 1 The monomer voltage display value is lower than that of the remaining monomer, and the actual voltage value of the monomer is compared.

If the actual value is higher than the display value, the actual value is standard to LMU with the actual value of the actual value. The monomer voltage is calibrated; if the measured value is consistent with the display value, the artificial power lithium ion battery is charged equalize. 2 Check the voltage sampling line is not broken, false; 3 replacement LMU; 4 to replace the fault dynamic lithium-ion battery pack.
