What are the maintenance rules for lead-acid batteries for electric vehicles in winter?

The maintenance rules for lead-acid batteries for electric vehicles in winter are in northern my country, which is extremely cold in winter. A cold environment has a greater impact on the working performance of the battery. In the winter, many drivers are overwhelmed by various problems caused by the battery. Why does this phenomenon occur in batteries every winter? This is because, because the battery relies on the chemical reaction of internal substances to supply electric energy to the car, and under lower temperature conditions, the chemical reaction of the battery itself will be attenuated, which causes this in the cold winter. The emergence of the phenomenon. To make a comparison: when the temperature of the electrolyte is 25°C, the capacity of the battery is 100%, when the temperature drops to -10°C, the capacity of the battery is only about 70% of that at 25°C. Therefore, if a battery with insufficient electrolyte or low electrolyte density is used in a low temperature, unexpected troubles such as difficulty in starting the engine will often be encountered, and it will also seriously affect the service life of the battery. Negative impact. In order to keep the battery in a good working condition, prevent unnecessary troubles, and extend the life of the battery. In winter, it is recommended that you always check the electrolyte of the battery to keep it in a sufficient state. It prevents the occurrence of serious problems such as the bending of the electrode plate, the rupture of the container and the fragmentation of the active material caused by the freezing of the electrolyte density, which directly lead to the battery scrap. In addition, if you want to add distilled water to the battery in winter, remember to do it when the engine is running or the engine is charging the battery. Otherwise, if the distilled water and the electrolyte are mixed unevenly, it is very easy to cause freezing. In addition, it should be noted that warm-up should be carried out when the car is started in cold winter, and the time to turn on the starter each time should not exceed 5 seconds, otherwise it will seriously affect the battery life.
