Daily maintenance tips for lithium batteries for electric vehicles

Do you know the daily maintenance tips for lithium batteries for electric vehicles? After the implementation of the new national electric vehicle standards, lithium batteries, as a new type of energy storage battery, are gradually replacing traditional lead-acid batteries. Compared with lead-acid batteries, lithium batteries have the advantages of high energy ratio, small size, light weight, environmental protection, and no recall effect. With the popularity of lithium batteries, the daily maintenance of lithium batteries has also affected the hearts of many consumers. What aspects should be paid attention to in daily maintenance of lithium batteries? The charger must be matched. The charger should match the lithium battery completely. Lead-acid battery chargers cannot be used directly. Excessive charger current will destroy the maintenance system of the lithium battery and form a short circuit, thereby causing a safety accident of the lithium battery. The charger voltage is too low, the charging efficiency is low, and it takes a long time. To master the correct charging method, first connect the charger to the battery pack, and then connect the charger plug to the 220V AC power supply. According to this connection sequence, prevent sparks when plugging and unplugging the charging plug. When the power is turned on, the charger displays a red light. Remember that light charge is very important. The basic principle of using lithium batteries is shallow charge and shallow discharge, that is, they should be charged in time, and the battery should be started when the battery is not connected to ensure that the battery voltage is maintained in a stable state. Deep discharge (over 90% of capacity) and charging will only damage the battery. When the lithium electric vehicle is not in use, the power should be turned off in time, otherwise the battery pack will stand out from the battery. Because the motor and controller will still consume power in the no-load state. Especially when the parking time is long, it is best to perform similar activation charge and discharge once a month to prevent the battery electrode from passivation and damage the electrode structure, thereby affecting the battery life. Prevent contact with metal, prevent metal objects from contacting the positive and negative electrodes of the battery, forming a short circuit and damaging the battery; do not knock, puncture, trample, modify, or expose the battery together to prevent danger.
