What are the repair and maintenance methods for electric vehicle batteries?

Electric vehicle battery repair methods: (1) High-voltage charging, deep discharge repair method (applicable to the battery with a reduced stroke of 1/2 battery) A. Use a 60V charger 48V battery to charge for 8 hours, B use a light bulb or electric stove wire to charge the battery Discharge to 0V, (no electricity at all), and discharge separately or in parallel when discharging. (2) Battery reassignment method (applicable to batteries with a reduced stroke of more than 1/2 of the battery car or drums): A selects the drums of the battery, replaces the old with the old, the load voltage of the battery is 11.4V12.7V, The terminal voltage is about 13.2V. B. Drive the battery car until it can’t run, set up the battery car to run idling, use a universal meter to measure the voltage of each battery separately, select the battery with the lowest voltage, replace the old battery with the old one, the load voltage of the battery is 11.4V12.7V, and the terminal voltage is at Around 13.2V. (3) For the above operations, it is better to add small coppersmith battery repair liquid, so that the effect is significant. Electric vehicle battery maintenance method: (1) is to add distilled water: A battery vehicle battery has been used for 6 months. When the B battery car's journey begins to shrink. (2) It is to add the activator of the small coppersmith nano carbon sol battery: A battery car is weak uphill, and the stroke is reduced by 1/3. B battery car battery has been used for about one year. (3) Keep the battery fully charged. If you ride an electric moped every day, no matter 10-15Km, you should recharge it to keep the battery full for a long time, and charge it on the same day. After vulcanization, the capacity drops. (4) Storage under power loss is prohibited: storage under power loss will seriously affect the service life. If the battery is idle for a long time, the damage of the battery will be more serious. (5) The battery is charged as it is used: When charging, the indicator light of the charger is red light first and then green light. After the light turns green, the floating charge should be guaranteed for 2 hours, which is good for inhibiting battery vulcanization. (6) Prevention of battery overcharging: A large amount of gas will wash out the electrode plate when the battery is overcharged, which accelerates the shedding of active material on the electrode plate and shortens the battery life. Overcharge of the battery accelerates the loss of water, causing the electrolyte to dry up and the temperature of the battery to rise, causing thermal runaway, expansion of the electrode plate, and deformation of the outer shell.
