What are common fault power lithium batteries

What are common fault power lithium batteries, power lithium battery in use what are the common fault? Common failure we guangdong power lithium battery manufacturer to tell you now! Power lithium battery fault causes 1, after full recharge let stand, single or several chain batteries voltage obviously on the high side, other monomers to normal. The cause of the problem: (1) acquisition error; (2) the LMU equilibrium function or failure; (3) batteries capacity is low, charging voltage rise quickly. 2, low battery voltage: after full recharge let stand, single or several monomer batteries voltage obviously low, other monomers to normal. The cause of the problem: (1) acquisition error; (2) the LMU equilibrium function or failure; (3) batteries self-discharge rate; (4) batteries capacity low, when the discharge voltage drops rapidly. 3, high temperature, battery system in a certain temperature or a few points on the high side, running or charge to alarm threshold. The cause of the problem: (1) temperature sensor fault; (2) LMU fault; (3) local heating electric connection exception; (4) fan is not open, poor heat dissipation; (5) near the motor heat source; 6. Charge. 4, ac charge fault fault reasons: (1) the battery failure ( Voltage, temperature, insulation etc. ) ； (2) the BMU fault ( Charging module or CAN) ； (3) the main negative abnormal, charging relay; (4) CC to ground resistance, the CP for abnormal voltage; (5) PE exception. 5, current abnormal failure reasons: (1) hall and its input and output circuit; (2) the hole against loading; (3) dc charging voltage or current to zero if the BMS demand, the charger in accordance with the minimum output power output. Conclusion: power lithium batteries common fault we introduce here, look at our power lithium battery manufacturers can realize more knowledge!
