Patrol car maintenance

1. It is strictly prohibited to lose power during storage.
Patrol car batteries are strictly prohibited from being in a depleted state when stored. Depleted battery status means that the battery is not charged in time after use. When batteries are stored in a depleted state, sulfation is likely to occur. Lead sulfate crystals adhere to the plates and block the ion channels, resulting in insufficient charging and reduced battery capacity. The longer the idle time is in the depleted state, the more serious the battery damage will be. Therefore, when the battery is not in use, it should be recharged once a month to better maintain the health of the battery.
2. Regular inspection
During use, if the driving range of an electric vehicle suddenly drops significantly by more than ten kilometers in a short period of time, it is very likely that there is a problem with at least one battery in the battery pack. At this time, you should promptly go to the sales center or agent maintenance department for inspection, repair or assembly. This can relatively extend the life of the battery pack and save you money to the greatest extent.
3. Avoid large current discharge
When starting a patrol car, carrying people, or going uphill, try to avoid slamming on the acceleration, which may cause an instantaneous large current discharge. High current discharge can easily lead to the formation of lead-acid crystals, thereby damaging the physical properties of the battery plates.
4. Correctly grasp the charging time
During use, the charging time should be accurately grasped according to the actual situation, and the charging frequency should be determined with reference to the usual frequency of use and mileage. During normal driving, if the red and yellow lights on the battery gauge are on, it should be charged; if only the red light is on, stop running and charge as soon as possible, otherwise excessive discharge of the battery will seriously shorten its life. After being fully charged, charge the battery if the running time is short. The charging time should not be too long, otherwise it will cause overcharging and cause the battery to heat up. Overcharging, overdischarging and undercharging will shorten battery life. Generally speaking, the average charging time of the battery is about 10 hours. If the battery temperature exceeds 65°C during charging, charging should be stopped.
5. Prevent exposure to the sun
Patrol cars are strictly prohibited from being exposed to the sun. An environment with too high temperature will increase the internal pressure of the battery and cause the battery to lose water, causing the battery activity to decrease and accelerating the aging of the plates.
6. Avoid the plug getting hot when charging.
Looseness of the patrol car's 220-volt power plug or charger output plug, oxidation of the contact surface, etc. will cause the plug to heat up. If the heating time is too long, it will cause the plug to short circuit or have poor contact, damage the charger and battery, and cause unnecessary losses to you. Therefore, when the above situation is discovered, the oxides should be removed or the connector should be replaced in time.
