How to maintain the battery in winter

Try to charge in a higher temperature environment, the best ambient temperature for charging is 25℃. At present, most chargers do not adapt to the automatic control system of ambient temperature, and most chargers are designed according to the ambient temperature of 25℃. Whether it’s temporary parking or charging, if possible, try to choose closed places such as underground parking lots and garages as far as possible. This is conducive to improving the activity of power lithium-ion batteries, which can not only reduce the loss of cruising range, but also improve the efficiency of charging. ,save time. When you go out, charge and warm up in advance to winter, there may be such a situation: the day before the electric car still has 70% of the electricity, but when I went to drive it one night, it was discovered that there was a leakage! In fact, this is not leakage, but the fault of low temperature. When the electric vehicle is running, the battery is in a state of continuing to discharge. During the discharge, the battery will heat up, so the battery itself is relatively hot and the battery voltage is relatively high. Therefore, you can see that the remaining power of the electric vehicle is still More. However, after parking for a whole night on a cold winter night, the battery has already cooled down and the voltage has dropped. At this time, the BMS will automatically adjust the displayed power and cruising range. This is the so-called leakage. Charge it for a while before going out to warm up, and there will be no similar leakage. When driving, try to maintain a constant speed while driving the car under your own feet. In the process of driving an electric car, you should accelerate and start slowly, and beware of violent driving methods such as violent acceleration, violent deceleration, violent turning, and sharp braking. Good driving habits, for fuel vehicles, can reduce fuel consumption and brake pad loss, for electric vehicles, it can effectively reduce brake pad loss and battery power consumption. Plan the mileage and leave room for yourself to drive an electric car in winter, the cruising range will generally drop between 10%-20%, about 15 kilometers -30 kilometers. However, as supporting facilities such as charging piles have not yet been fully popularized, it is necessary to plan the itinerary before traveling to reserve room. Otherwise, the battery of the electric car flashes red and there is no place to charge it, then it will be troublesome! When parking, if the battery is over-discharged and the vehicle will not be used for a long time, the negative electrode of the battery should be unplugged. Since there is also a weak current consumption in the vehicle's circuit system when parking, leaving the vehicle for a long time will cause the battery to run out. Therefore, for vehicles that have not been used for a long time, the negative electrode of the battery should be unplugged to beware of excessive battery power consumption. When parking and waiting, do not use high-power electrical appliances. High-power electrical appliances include headlights, fog lights, seat heating, audio, air conditioning, etc. The easiest way is to try to fully discharge, and continue to charge for a period of time after the vehicle is overcharged. Just like the mobile phone software, regular upgrades and program updates are also necessary. In addition, if there is no special power requirement, it is recommended to drive the vehicle in a pure electric economy mode. Do not use unqualified or modified power strips or charging devices to charge, and charge the vehicle when it is not used for a long time before storing. Although these are basic knowledge of maintenance, they cannot be ignored. Pay attention to the charging and discharging range of the car battery. When the battery level is displayed at 50% 70% or the yellow light is indicated, it is best to charge once.
