2. No power failure during storage: No power failure during battery storage. The state of insufficient power means that the battery is not charged in time after use. When the battery is stored in a state of insufficient electricity, it is easy to be sulfated, and the lead sulfate crystal adheres to the electrode plate, which will block the ion channel, lead to insufficient charging and decrease the battery capacity.
The longer the battery is idle, the more serious the battery damage is. Therefore, when the battery is idle, charging it once a month can better keep the battery healthy.
3. 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 fully charged, charge the battery for a short time, and the charging time should not be too long, otherwise it will be overcharged and the battery will heat up. Overcharging, overdischarge and undercharge will shorten the battery life. In general, the average charging time of a battery is about 10 hour. If the battery temperature exceeds 65℃ during charging, please stop charging.
4. Check the tire pressure frequently: To keep the tire pressure at the correct tire pressure, you must check the tire pressure every two weeks or at least once a month. Incorrect tire pressure will cause power consumption, short driving mileage, reduce driving comfort, reduce tire life and reduce driving safety.
5. Avoid plug heating when charging: 220 volt power plug or charger output plug is loose, and the contact surface is oxidized, which will lead to plug heating. If the heating time is too long, it will lead to short circuit or poor contact of the plug, damage the charger and battery, and bring unnecessary losses to the owner. Therefore, when the above situation is found, the oxide should be removed in time or the connector should be replaced.
6, to prevent exposure: electric vehicles are strictly prohibited in the sun exposure. 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.
7. Regular inspection: During use, if the continuous mileage of the electric vehicle suddenly drops by more than ten kilometers in a short time, it is likely that there is something wrong with at least one battery in the battery pack. At this time, you should go to the sales center or the maintenance department of the agent in time for inspection, repair or matching. This can relatively prolong the life of the battery pack and save money to the greatest extent.

Other important considerations for new energy steam:
1, check whether the power is sufficient, whether the braking performance is good, whether the screws are loose, etc. Before leaving the car every day. If there is any fault, it should be repaired and eliminated in time. Only after the inspection is completed and it is determined that there is no fault can the car leave.
2. Turn off the power switch every time you stop, pull out the key, turn the gear switch to neutral and pull the handbrake.
3. Children should turn off the key switch when playing in the car to avoid danger.
4. Charging should be carried out where children can't reach.
5. When repairing or replacing the charging fuse of the charging part, the plug of the 220V power supply must be unplugged first, and live operation is not allowed.
6, maintenance or replacement of batteries, electrical appliances, must turn off the power switch after operation.
7. Before driving the electric car, check whether the door is closed.
8. In case of fire caused by accident or other reasons, turn off the main power switch immediately.
