Maintenance analysis of electric vehicle battery

Pay attention to the charging time in winter. First of all, the number of charging cycles of the battery is constant, the number of cycles of charging and discharging lead-acid batteries is 300 to 400 times, and that of lithium batteries is more than 500 times. Therefore, do not charge and discharge frequently, but charge when the battery is about 30% remaining, which can slow down the degradation of battery capacity. Do not cut off the power immediately after the battery overflows. It is recommended to delay the recharge for 1~2 hours, but the total charging time cannot exceed 12 hours, because long-term overcharging will harden the active material on the plate, and cause it in severe cases. Loss of water or deformation. Good driving habits are crucial. In winter, the riding habits of drivers are very important to the maintenance of electric vehicle batteries. Try to be alert for sudden acceleration or sudden braking during riding. In case of uphill, bridge, headwind or overweight driving, you must pedal to assist, and you must not overload or continue to drive when the battery is running low. . Charging the car in winter is very important. When charging the battery of an electric vehicle in winter, the electric vehicle should be kept upright as much as possible, and the situation of charging outdoors should be minimized as much as possible. Because the outdoor temperature is cold in winter, the battery is easy to freeze and frost. Leave it for a while before charging the battery, and wait until the surface temperature of the battery rises to close to room temperature and is sufficiently dry before charging. In winter, the electric vehicle is idle, but the battery cannot be idle. Lead-acid batteries are especially afraid of losing electricity to discharge. Lead-acid batteries that lose electricity may be permanently damaged if they are left for 3 to 7 days. Therefore, the batteries should be charged as soon as possible after use. Regarding the battery that has not been used for a long time, the battery should be recharged at regular intervals to compensate for the self-discharge power loss when the battery is stored. Replace big-brand batteries and don't use chargers indiscriminately. If the electric vehicle has experienced frequent cycling in summer, it is necessary to test the remaining power of the vehicle battery. If the battery loss is relatively large, it is recommended that the user replace the battery with a new one after the winter, and when buying a new battery, also bring the battery charger with the standard battery, try to achieve one charge and one charge, and it is best not to mix the chargers. .
