Repair and maintenance methods for electric vehicle batteries

The battery repair and maintenance methods of electric vehicles include: Electric vehicle battery repair methods: Because we did not maintain the car battery, what should I do if the car battery stroke is reduced by 1/2 or less? Follow the instructions below to repair the battery yourself to ensure that the battery The new same recovery, more than a year. (1) High-voltage charging and deep-discharging repair method: (applicable to the battery whose stroke is reduced by 1/2) Use a 60V charger to charge the 48V battery for 8 hours. Discharge the battery to 0V with an electric light bulb or electric stove wire (without electricity), and discharge them separately or in parallel. (2) Battery rearrangement method: (Applicable to batteries with a stroke reduced by more than 1/2 or with drums) A. Select the drum battery and replace the old battery. The battery load voltage is 11.4v-12.7v, and the terminal voltage is about 13.2v. B. Run the battery car until it cannot run, set the battery car to an idle state, measure the voltage of each battery with a multimeter, select the battery with the lowest voltage, and replace the old battery with the old battery. The battery load voltage is 11.4v-12.7v, and the terminal voltage is about 13.2v. The above operation is best to add small coppersmith battery repair liquid, so the effect is significant. 2. The maintenance method of electric car battery: (1) is to add distilled water: an electric car battery has been used for 6 months. When the battery car's mileage began to shrink. (2) Add activator to the small copper Smith nano carbon sol battery: when the battery car A is weaker when climbing, the stroke is reduced by 1/3. B battery car battery has been used for about a year. (3) Keep the battery fully charged. If you ride an electric moped every day, no matter 10-15 kilometers, you have to charge it, let the battery be full for a long time, and charge it on the same day. (4) Loss of power storage: battery storage loss will seriously affect the service life, if the standby time is longer, the battery damage will be more serious. (5) Charging after use: When charging, the indicator light of the charger will be red and then green. After the green light is on, the charger should float for 2 hours, which is beneficial to inhibit the battery from curing. (6) Prevent battery overcharging: a large amount of gas will be generated during battery overcharging, clean the electrode plate, accelerate the active material of the electrode plate to fall off, and shorten the battery life. Overcharge of the battery will accelerate the loss of water, cause the electrolyte to dry, and the temperature of the battery will rise, leading to thermal runaway, expansion of the electrode plates, and deformation of the casing.
