Electric vehicles have many long-term charging hazards

In an interview recently, it was learned that some people think that in order to ensure that the electricity is sufficient, electric vehicles can always be charged when they are not used. Miss Xu, a citizen of Penglai, told the reporter: "I usually fill it once a day and a half. Generally, I don't want to go down again in the evening. "There are not a few people who charge electric cars for a long time like Ms. Xu. Then how long should electric cars be charged? According to electric vehicle dealers, the charging time of electric vehicles should not exceed eight hours, otherwise it is easy to reduce the service life of electric vehicle batteries. And if the battery is older, it also needs to reduce the charging time appropriately. Jiyiling, an electric car salesman, said: "Don't charge it for a long time, or fill it overnight, or for two or three days. Regardless of it, the battery is easy to fill and the battery will become obsolete. "

Sales personnel told reporters that the chargers are now equipped with small fans to facilitate heat dissipation, and generally do not cause fires due to the heat generated by the long charging time, and firefighters reminded the general public that electric vehicles should be far away from flammable and explosive items during the charging process., Otherwise, the heat generated during the charging process can easily cause accidents. In addition, if the charging time is too long, the battery is damaged and the charger is short-circuited.
