Scientific lithium battery charging method

40 degrees high temperature, or to charge the electric car like this? No wonder the battery drums! As summer approaches, the temperature is getting higher and higher. The temperature in some areas has reached 40~42℃. During the charging process, the battery generates heat and the battery temperature rises above 50°C. In summer, pay special attention to the charging of electric vehicles. Improper charging can cause damage to the electric vehicle batteries. Simply recharging drum batteries can reduce battery life. The following charging methods are the most harmful to the battery and should be prevented as much as possible. Choose a scientific charging method: there is no error. 1: Charge the battery as soon as the electric vehicle stops. The correct approach is: first park the electric car for more than half an hour and wait for the battery to cool down, and then charge it. In the cycling state of an electric vehicle, the battery itself will heat up. In addition to the hot weather, the temperature of the battery can even reach 70°C or more. At this time, charging the battery will add water loss to the battery, reduce the battery life, and add a new battery. The risk of drumming. 2. The electric vehicle charges the battery under direct sunlight. The correct approach: try to charge the battery in the shade, or choose to charge the electric car in the evening. The battery will also become hot during the charging process. If it is charged in direct sunlight, it will also cause the battery to lose water and cause damage to the battery. Fault 3. The charging time is more than 8 hours or even a whole night. The correct way is to control the charging time within 8 hours regardless of whether the charger has a rotating light. Many electric vehicle users often charge overnight for convenience. The charging time often exceeds 12 hours. Sometimes they forget to plug in the power source and charge for more than 20 hours. This is bound to cause great harm to the battery. Repeated charging for a long time will only cause the battery to fail to charge due to overcharging. Fault four, the electric car charger is not used as a special car charger. The correct method is: the charger is dedicated to the car. If it is damaged, please go to the auto repair shop or repair shop to check it by a professional, and then replace it with a new charger. Now many families have more than two cars and electric cars, and many electric cars are different brands, different types, and different battery types. The chargers are also different. It is not common. It is the correct car charger, but some In the process of user use, electric vehicles are often mixed, and even use 60v, 48v battery chargers to charge 1220 AA batteries. The charging voltage and current do not match, which will damage the battery formation. Wrong 5. Use a non-brand charger to charge the battery. The correct way is: go to a professional electric car shop or repair shop to buy a regular brand charger. At present, the electric vehicle market is flooded with many chargers. Many consumers do not pay attention to the quality of the chargers and are greedy for cheapness, believing that the chargers can only charge the battery. The electronic components of non-brand chargers are basically inferior materials, which are easily damaged. The problem that often occurs is that the battery does not turn on when the battery is fully charged, and the charging current cannot be adjusted according to the current of the battery, causing many batteries to overcharge. After repeated charging, the battery will charge the drum. If the electric vehicle charger cannot be used normally, important professional electric vehicle after-sales repair shops replace high-end brand chargers to ensure the charging quality and extend the battery life. Fault 6. Use a fast charging station to charge the battery. Correct approach: Check the power before going out to ensure that the electric vehicle has normal power to meet travel needs. If the power is insufficient, go out and charge in time. Nowadays, many cities have many fast charging stations. On the one hand, they bring convenience to electric vehicle users. On the other hand, the high current of fast charging stations rechargeable batteries causes serious gas loss and water loss. Long-term use of battery charging drums is also an important reason. Some electric vehicle users report that they can be charged within half a year after the battery is replaced. This is the result of repeated use of the fast charging station. Fault seven, the electric car charger is equipped with the car. The correct approach: the charger should be stored in a fixed place, if available, it can be equipped with a charger. Some electric vehicle users, for convenience, are like the charger on the car. In fact, the welding of the electronic components on the motherboard, the lumps of some large electronic components, may form welding, resulting in poor contact and forming a charging current.
