What are the maintenance methods for electric vehicle batteries?

1. Don't cut off the speed limit line of the controller's speed limiter by pursuing too high speed. The discharge current is roughly proportional to the'speed' and'resistance torque', especially during the acceleration phase, the discharge current will increase exponentially , Continuous high-current discharge, intense electrochemical reaction in the battery, will cause the battery plate to deform, active material fall off, electrolyte oxygen evolution, hydrogen evolution, resulting in battery loss of water, these conditions will shorten the battery’s service life, or even cause failure. Repair the damage. 2. Charge in time. The salt reaction (sulfurization reaction) starts when the electric vehicle battery is discharged. Charge in time can convert the active lead sulfate into active spongy lead and lead dioxide in time. After the electric vehicle battery is used If it is left for more than 12 hours, the active lead sulfate inside will crystallize into larger crystal particles again and become irreversibly salted (sulfided). If the battery can be charged in time every time you ride, and the battery is in a shallow cycle state, the service life of the battery will be prolonged. 3. Use a special charger when charging, and don't change the charger at will. When the electric vehicle is in the OEM, the charger is matched with the battery. The supplementary current, maximum charging voltage and conversion current, floating charging voltage, and floating charging current are specified. The parameters of other chargers have a certain range of differences, which are likely to be incompatible with the configured battery, so it should not be arbitrarily Replace the charger. The charger will cause parameter drift in strong vibration and turbulence. When used in a poorly ventilated environment, the temperature of the charger can reach about 70℃, which will cause thermal drift of the parameters, which will affect the normal operation of the charger and cause overcharging of the battery. , Undercharge and other damages. Therefore, we must protect the charger of the electric vehicle battery! In addition, the charger must have the function of floating charge. When the indicator light of the charger is on, it only means that the charged power reaches 97%-99% of the total capacity, and the floating charge (trickle) charging should be continued for 2 hours. Make it completely full. 4. When the electric vehicle is not used for a long time, it is necessary to replenish the power of the electric vehicle battery in time, and avoid losing electricity storage. When the electric vehicle battery is not in use, it should be replenished once a month. When storing, it must be fully charged and then stored. , Resulting in damage to the battery! 5. Keep the battery warm in winter. People are afraid of cold, and the battery is also afraid of cold. The temperature is low in winter, and the battery's charging acceptance ability becomes very poor. It is best to put the electric vehicle indoors when charging! This way the battery will be fully charged!
