How to maintain large-capacity lithium-ion batteries in winter

According to the reporter's interview, in winter, as the temperature drops, many electric vehicles will suffer from problems such as charging failure or failure to start. The battery in an electric vehicle is susceptible to external temperature. Therefore, if the battery is too high or too low, it will cause storage problems and shorten its service life. The following is a summary of the winter maintenance of electric vehicle batteries. Regarding electric vehicle batteries, the best charging time is to keep the battery in an infinite cycle, thereby extending battery life. If the voyage is very long, please charge over time. The vulcanization process begins after the battery is discharged, and charging on time cannot eliminate less vulcanization and shorten the battery life. Therefore, in addition to regular charging, pay attention to charging as soon as possible after use to ensure that the battery is fully charged. In addition to recharging, atrial transfer should be performed regularly, which will help activate the battery. 1. In the cold winter, the electric vehicle battery is easy to run out of electricity, so it can be used and charged when possible. Never use it at a loss. The short run in the cold winter is reflected in the lack of durability of the battery. Due to the low temperature in the cold winter, the battery capacity is significantly reduced and the mileage is reduced, which interferes with the mileage. This is the principle problem of the lead-acid battery and there is no way. 2. Cultivate good usage habits, do not brake too frequently, do not unplug the speed limiter, do not overload, start up relatively slowly, do not yank the switch. The nominal capacity of a lead-acid battery is determined by the capacity when the ambient temperature is 25°C. The battery capacity will change with the change of the ambient temperature. The higher the ambient temperature, the higher the capacity, the lower the ambient temperature, and the lower the capacity. 3. When charging, it should be carried out in the room as much as possible, and the charging time should not exceed 12 hours. Charge as you use it, charge shallowly. In the cold winter, the activity of the lithium ion battery is reduced, which is very easy to cause overdischarge and overcharge, which may interfere with the service life of the battery, and may cause a safety accident. 4. When not in use for a long time, the lithium ion battery should be removed and placed in a cool place with dry air Place. The freezing must not be carried out to prevent water vapor erosion. Prevent it from being used in a high-temperature car. If stored for a long time, charge the battery to 40% before storing.
