Detailed explanation of the precautions for the use of electric vehicle batteries

1. Irregular use of chargers, mixed chargers: Due to the portability and practicality of electric vehicles, many families have one or two electric vehicles, and some users randomly mix chargers: 1. Often the nominal voltage of the battery pack is 48V, but 60V is used. When the battery charger is charging, due to the voltage mismatch, the voltage will be too high and the battery will be overcharged, which will affect the performance and service life of the battery. More seriously, it will cause the internal temperature of the battery to rise and lose control and cause serious safety accidents. . 2. Now is the stage where lithium-ion batteries are gradually replacing lead-acid batteries. Some users have both lead-acid battery electric vehicles and lithium-ion battery electric vehicles in their homes, because it is easy to mix lead-acid and lithium-ion battery chargers. Due to the different material systems of the two batteries, the charging voltage, charging mode, etc. are not the same. It is also very dangerous to mix chargers with two different types of batteries. Therefore, the mixed use of chargers is very dangerous, it is very easy to directly damage the electric car, and even cause fire and explosion. The fires and explosions of electric vehicles that you often see are mostly caused by improper use. 2. Irregular charging and bad charging habits. Some consumers have very random charging, such as: charging immediately after riding, charging in high temperature environments, frequent charging, overcharging, etc. The result of this will affect the performance of the battery And longevity. Therefore, it is recommended to unplug it immediately to stop charging after the charging turns to the green light. Therefore, it is recommended that the charger is dedicated to the car, fully charged and unplugged in time, and develop good habits. 3. Battery short-circuit and damage. If a single battery is short-circuited, the battery temperature will be too high. In this regard, the correct approach is to immediately go to a professional battery repair point for inspection and repair. You can select batteries with the same specifications and performance for group replacement. If the results are not good after replacement, replace the entire battery group. A battery short circuit is quite dangerous and can easily cause safety accidents. Fourth, battery aging and damage during use. Most electric vehicles will be equipped with batteries by electric vehicle manufacturers when they leave the factory. However, as time goes by, the batteries will age or be damaged due to various reasons after they have been used for a long time. At this time, the service life of the battery is nearing the end, and the battery will experience temperature or even fire and smoke when charging or discharging the battery for a long time. At this time, it is recommended to replace the electric vehicle battery immediately to prevent more dangerous situations. Fifth, the use environment does not meet the requirements 1. The charging of electric vehicles has high environmental requirements, and it is necessary to choose a well-ventilated and cool place for charging. Daily consumers often charge electric vehicles in a high-temperature environment, directly exposed to the sun, or charge in a sweltering enclosed environment, which will easily cause battery thermal runaway, which may damage electric vehicle accessories or even catch fire; 2. Frequently It is very dangerous to see consumers riding electric cars in deep water. Water in the battery can easily cause internal short-circuits to damage the parts, which can cause serious safety accidents. Therefore, electric vehicle batteries are strictly prohibited to be used in high temperature and humid environments. Therefore, it is recommended that you use it strictly in accordance with the requirements of the manual during daily use. 6. The prerequisite for using inferior batteries to pay attention to daily maintenance is: choose high-quality electric car batteries! Inferior battery life is short, there is no guarantee after sales, and it is prone to safety hazards. Therefore, it is necessary to purchase high-quality electric vehicle batteries produced by regular battery manufacturers through regular channels.
