With the continuous popularization of electric vehicles, they have gradually become an indispensable means of transportation for people’s daily lives. Electric vehicles rely on DC batteries to store electrical energy to obtain kinetic energy. Therefore, the quality of batteries directly affects the distance and life of electric vehicles. For a long time, for this reason, only by strengthening the usual maintenance, can you better provide a continuous source of power for your car. So, how do you better maintain your battery?
Tip 1: It is strictly forbidden to lose electricity when storing
The battery is strictly prohibited to be in a state of power loss when it is stored. The state of power loss means that the battery is not charged in time after use. When the battery is stored in a power-deficient state, it is prone to sulfation. Lead sulfate crystals adhere to the electrode plate, blocking the ion channel, causing insufficient charging and decreasing battery capacity. The longer the idle time in the power-deficient state, the more severe the battery damage. Therefore, when the battery is not in use, it should be recharged once a month to better maintain the battery health.
Technique 2: Regular inspection
In the process of use, if the continued mileage of the electric vehicle suddenly drops more than ten kilometers in a short time, it is very likely that at least one battery in the battery pack has short-circuit phenomena such as broken grids, softening of the plates, and falling off of active materials on the plates. . Once the problem is found, you should go to a professional battery repair organization for inspection, repair or assembly in time, so that the life of the battery pack can be relatively extended, and expenses can be saved to the greatest extent.
Tip 3: Avoid high current discharge
When the electric vehicle starts, carries people, or goes uphill, please use your pedals to help. Try to avoid instantaneous high-current discharge. High-current discharge can easily lead to lead sulfate crystals, which will damage the physical properties of the battery plates.
Tip 4: Correctly master the charging time
During use, you should accurately grasp the charging time according to the actual situation, refer to the usual use frequency and mileage, and also pay attention to the capacity description provided by the battery manufacturer, as well as the performance of the supporting charger, the size of the charging current and other parameters to grasp the charging frequency . Generally, the battery is charged at night, and the average charging time is about 6-8 hours. If it is shallow discharge (the driving range is short after charging), the battery will be fully charged soon, and overcharge will occur if the battery continues to charge, which will cause the battery to lose water, heat, and reduce the battery life. Therefore, it is best to charge the battery once when the depth of discharge is 60%-70%. In actual use, it can be converted into riding mileage, and necessary charging according to the actual situation to avoid harmful charging.
Tip 5: Prevent exposure
Electric vehicles are strictly prohibited from being exposed to the sun! An excessively high temperature environment will increase the internal pressure of the battery and the battery pressure limiting valve will be forced to open automatically. The direct consequence is to increase the battery's water loss. Excessive battery loss will inevitably lead to a decrease in battery activity and accelerate the softening of the plate. Fatal injuries such as body heating, bulging and deformation of the shell.
Tip 6: Avoid plug heating when charging
Loose charger output plugs and oxidation of the contact surface will cause the charging plug to heat up. Excessive heating time will cause the charging plug to short-circuit, directly damage the charger and cause unnecessary losses. Therefore, when the above situation is found, the oxide should be removed in time or the connector should be replaced.
As a consumable, the life of the battery has a lot to do with the usual maintenance and maintenance, but according to common sense, the general life of the battery will be about 3 years, and some will be maintained in 5 years. So, for you For your car, battery maintenance is very important.
