2) Avoid plug heating when charging: loose power plug or charger output plug and oxidation of contact surface will lead to plug heating, and too long heating time will lead to plug short circuit or poor contact. When the above situation is found, remove the oxide or replace the connector in time.
3) No power failure during storage: No power failure during storage of batteries. When the battery is idle, it should be charged once a month, which can better maintain the health of the battery.
4) Prevent exposure: Don't expose new energy vehicles to the sun. High temperature environment will increase the internal pressure of the battery, make the battery lose water, lead to the decline of battery activity and accelerate the aging of the pole piece.
5) Accurately grasp the charging time: during use, accurately grasp the charging time according to the actual situation, and grasp the charging frequency with reference to the usual use frequency and mileage. When driving normally, if the meter indicates that the red light and yellow light are on, it should be charged; If only the red light is on, stop running and charge as soon as possible, otherwise the battery's excessive discharge will seriously shorten its life. After being fully charged, it should be recharged after running for a short time, and the charging time should not be too long. Overcharging, overdischarge and undercharge will shorten the battery life.
