Electric car battery: four situations to be deactivated

Electric car batteries: Four situations to stop the electric car and burn it halfway. Anyone who encounters this kind of thing will be frightened, and then depressed: a car worth thousands of dollars is burned into scrap iron. Professionals analyze that spontaneous combustion of electric vehicles during driving or charging is mostly related to battery quality. Counterfeit and shoddy batteries generally use inferior materials, and the quality of most of their key raw materials is not good enough. The battery should be disabled when the following four conditions occur: one is that the use time after charging is severely insufficient; the other is that the battery cannot be charged; the third is that the battery is overheated during use; the fourth is that the appearance is swollen and broken. Professionals remind you not to buy cheap batteries for cheap. When purchasing batteries, be sure to read the processing date, certificate of conformity, after-sales service and other related certificates. Regular manufacturers generally provide one year of after-sales service. In addition, in use, it is best to control the charging time, generally not more than 8 hours. Cars should also pay attention to daily maintenance. Frequently check the air switches and circuits, and update the aging wires in time. Once you find any peculiar smell in the car, you must send it for inspection in time. Six Tips for Maintaining Electric Vehicle Battery Electric vehicles are deeply loved by consumers because of their lightness and pollution-free advantages. The mileage is one of the important criteria for consumers to weigh the quality of electric vehicles. Therefore, battery problems account for more than 95% of many electric vehicle quality complaints. Therefore, the battery is an important factor in determining the mileage of electric vehicles, and is a key component of electric vehicles. So what issues should be paid attention to in the ordinary maintenance of electric vehicle batteries? Tip 1: It is strictly forbidden to lose electricity during storage. The battery is strictly forbidden to lose electricity during storage. 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. Tip 2: Periodic inspection. During use, if the continued mileage of an electric vehicle drops abruptly by more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery pack has broken grids, softened plates, and activated plates. Short-circuit phenomena such as material shedding. At this time, you should go to a professional battery repair organization for inspection, repair or assembly in time. This can relatively extend the life of the battery pack and save money to the greatest extent. Tip 3: Prevent high-current discharge When an electric vehicle starts, carries people, or goes uphill, please use your pedals to help prevent instantaneous high-current discharge. High-current discharge can easily lead to the initiation of lead sulfate crystals, thereby damaging the physical properties of the battery plates. Tip 4: Correctly grasp the charging time During use, accurately grasp the charging time according to the actual situation, refer to the usual frequency of use and mileage, and also pay attention to the capacity description provided by the battery manufacturer, as well as the performance and charging current of the supporting charger The size and other parameters control the charging frequency. Generally, batteries are charged at night, and the average charging time is about 8 hours. If it is a shallow discharge (the driving range is short after charging), the battery will soon overflow, and continuous charging will cause overcharging, which will cause the battery to lose water and 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 is carried out according to the actual situation to prevent harmful charging. Tip 5: Beware of exposure to the sun. It is strictly forbidden to expose electric vehicles 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 straight result is the water loss of the newly added battery. Excessive battery loss will inevitably lead to a decrease in battery activity, accelerate the softening of the plate, and charge. When the shell heats up, the shell bulges, deforms, and other fatal injuries. Tip 6: Prevent plug heating during charging. The loosening of the charger output plug and the oxidation of the contact surface will cause the charging plug to heat up. If the heating time is too long, it will cause the charging plug to short-circuit, directly damage the charger, and cause unnecessary losses. Therefore, when the above situation is discovered, the oxide should be removed in time or the connector should be replaced. In general, maintaining a key component such as the battery is very beneficial in terms of extending the life of the electric car itself. At this event, in addition to the group purchase of the electric car, there will be professional maintenance personnel on-site to check the pulse of your car.
