The use and maintenance of electric vehicle battery

Lead-acid battery is now electric vehicles mainly adopts batteries, battery is not filled with bad but bad, it is by no means alarmist, battery performance depends on the service life of the battery and use performance plays an important role, must pay attention to. 1, the battery discharge depth had a great influence on the service life of the battery cycle, this is because the more deep, the depth of discharge electrode expansion shrinkage, the greater the fall off of the positive active material, the more to lose discharge characteristics, performance degradation, until the life end. So the battery should try to avoid depth discharge when using, do shallow put frequently charge, generally should be: the battery to discharge depth is 50% When 70% charge their best. 2, after the battery discharge to the termination voltage, continue to discharge ( Over discharge) Would result in grave damage to the battery, this is because at this time are irreversible sulfate, so that the charging resilience, even beyond repair. So when using, should prevent battery discharge, under-voltage protection is effective measures. 'under-voltage protection measures are controlled by the electric vehicle controller, but because of the electricity appliance such as electric meter and the indicator light is not controlled by the controller, so I started electric bicycle locks once closed, while the current is small, but if long time discharge, discharge battery will be seen. Therefore, may not be long time open the lock, should immediately turn off when not in use. 3, should be less than or equal to the battery charging current acceptable charging current, otherwise, the charging of excess current liquid can make the electrolysis of water consume too readily, and generate serious phenomenon of the analysis of gas, after a long time will make very difficult charging, so charging for as much as possible to prevent charging. Normal manufacturer production in the right charger to ensure battery charging. 4, lead-acid battery, especially afraid of deficient electric discharge, deficient place 3 - electric batteries 7 days, is likely to be permanently damaged, therefore, after the battery, please charge as soon as possible. For does not use the battery for a long period of time, about every 15 days on a single battery charge, to compensate the self-discharge of battery storage capacity loss. 5, battery run in high temperature season, the main recharge problems existed. Summer, therefore, should try to reduce the temperature of the battery, ensure good heat dissipation, prevent the strong sunlight after charging, and stay away from heat source. Under the condition of low temperature, charging mainly accept ability difference, battery deficiencies caused by loss of battery. Cryogenic insulation antifreezing measures should be taken, especially when charging, should be put in a warm environment, to ensure adequate electricity, prevent the formation of irreversible sulfate, prolong the service life of the battery. 6, in general, the depth of discharge larger battery service life in 1 year or so, the depth of discharge in 50% About 70% of battery life in a year and a half. Individual manufacturers battery can reach more than 2 years.
