Winter new energy pure electric vehicles are often the most difficult season for new energy vehicles. After entering the winter, the temperature decreases, which will lead to a decrease in the electrochemical properties of the battery, the charging rate of electric vehicles will be reduced, and the endurance will be greatly reduced, which makes charging energy supplemental electric vehicles a problem, some of which are worse, so low temperature has always been a problem that plagues electric vehicle manufacturers and user electricity. Not long ago, Weima was also attacked by the first group of car owners for "locking electricity".
Previous trials have confirmed that when 80%
Therefore, in the new energy vehicle industry, it is generally believed that lithium batteries are most ideal for charging and discharging between 20% and 80%, which not only ensures the safety of the battery, but also maintains the life of the battery without decay. The "lock electricity" in the main mouth of the Wei carriage should be more accurately expressed as the ideal safety voltage controlled by the manufacturer in the middle, which can theoretically extend the battery life to more than 10 years. And it can be seen that the "lock electricity" claimed by the owner of the Wei carriage is not a large-scale, full range of car "lock", but concentrated in the first batch of car owners in 2018, seemingly "locking electricity", in fact, it is more for the elongation of battery life.
