Several major culprits that damage electric car batteries

There are several important reasons for damaging the battery of electric vehicles. It should be noted that the battery is the core part of electric vehicles during the high temperature in summer. However, with the advent of summer, many electric vehicle users obviously feel that the situation of electric vehicle drums is new and the temperature continues to rise. Allow it to develop, not only is it inconvenient to ride a bicycle every day, but it is also easy to cause fires, and there is a huge safety hazard. So, what are the reasons for battery swelling in summer and how to prevent it? What problems should be paid attention to when using electric vehicles in summer? Let us answer these questions one by one: Do you have to choose a special high-quality charger? The charging problem has been said many times, but There are still many users in the process of using, electric vehicles often mix chargers, and even use 60v, 48v battery chargers to charge the 1220 ah battery, the charging voltage and current do not match, forming a battery short circuit or insufficient charging , Especially in the hot summer, when using the charger and the battery parameters do not match, charging and a long time may cause the battery to be overcharged. Overcharge will increase the loss of battery fluid and weaken the battery capacity. Over time, the light will make the battery swell , Or until it expires. Moreover, the charging of electric vehicles catches fire, and many times the ignition point is the charger. The exhaust volume is small, the life is short, the time is long, and the work efficiency is reduced. Charging cannot get good heat dissipation. At this time, as long as you put the charger on the cushion of the electric car, it is easy to cause a fire. Charge the battery after it cools down. Many electric vehicle users choose to replace the battery immediately after charging. However, there is a problem: the battery itself will have a fever under cycling conditions, and the temperature of the battery can be as high as 70°C in the hot summer. Above, this time if not only the direct loss of charging water for the new battery, but also reducing the battery life, the battery will even exceed the critical point due to the rise in temperature, which will eventually lead to spontaneous combustion. Therefore, it is recommended to stop the electric vehicle for 1-2 hours after driving and wait for the battery to cool down before charging. Pay attention to the charging environment and advocate charging at dusk. In addition to preventing high temperature exposure and rainy days, charging of electric vehicles in summer must be carried out in a cool and ventilated environment. The battery will also generate heat during the charging process. If it is charged in direct sunlight, it will Cause the battery to lose water and damage the battery. Charging at night is prone to problems such as charging safety hazards, so it is recommended to charge the electric vehicle at dusk. Check regularly to observe whether the steel plate has vulcanization. Vulcanization means that the electrode plate will gradually be covered by lead sulfate crystals due to electrochemical reaction during the battery use, reducing the reaction area between the electrolyte and the electrode plate, resulting in a decrease in battery capacity. The conductivity of lead sulfate is not good, the resistance is large, and the solubility and dissolution rate are very small. When the charging recovery is difficult, it will also cause battery drums and damage. Therefore, when the electric vehicle rides the application every day, you must pay attention to the maintenance of the electric vehicle, especially in In the hot summer, you should also pay attention to regular inspections. At the same time pay attention to the small details of the day, do not put gas lighters, fresh air agents, mosquito repellents and other items on the car to prevent fires and explosions caused by high temperature and thermal expansion in summer.
