Winter electric cars are also afraid of cold battery charging to delay
Recently, many people have come to reflect that their car is not as good as before. It feels that the battery is broken. In fact, due to the arrival of winter, the temperature has dropped, which has a certain impact on the battery energy.
Electric cars can run more than 100 miles in the summer, and now can only run less than 80 miles. Is the quality of this electric car too bad?
Due to the principle of thermal expansion and contraction, the energy storage capacity of a normal lead-acid battery is reduced. Therefore, if the battery is charged once, the mileage of the car will decrease compared with other seasons. Please do not worry.
In the low temperature condition, the battery generally has the problem of poor charging acceptance and insufficient charging. At this time, it is necessary to increase the charging voltage and prolong the charging time, and take measures of heat preservation and antifreeze, so as to ensure sufficient power and prolong the service life of the battery. Recharge the battery and do not charge it until the battery is used up. It is better to use half of the battery. In addition, in order to prevent the battery from being frozen, the electric vehicle battery can be placed in a room with a higher temperature when not in use, and should not be placed directly on the ground. If the battery cannot be removed, you can park the electric car in the house overnight.
