An introduction to the secret of longevity of the battery of the breakfast car, electric sightseeing car
During use, if the continued mileage of the electric sightseeing car suddenly drops more than ten kilometers in a short time, it is very likely that at least one battery in the battery pack has broken grids, softened plates, and activated plates. Short-circuit phenomena such as material shedding. At this time, you should go to a professional battery repair organization for inspection, repair or assembly in time.
Do not lose electricity storage
The power-deficient state means that the battery of the electric sightseeing car is not charged in time after use, and it is prone to sulfation. Lead sulfate crystals are attached to the plate and block the electricity. Ion channels cause insufficient charging and decrease battery capacity. The longer the idle time in the power-deficient state, the more serious the battery is damaged. When the battery is not in use, it should be recharged once a month, which can prolong the service life of the battery.
Master the charging time
Generally, the battery is charged at night, and the average charging time is about 8 hours. If it is shallow discharge (the mileage is short after charging), the battery of the electric sightseeing car will be fully charged soon, and the battery will be overcharged if it continues to be charged, which will cause the battery to lose water and heat, and reduce the battery life. Therefore, it is best to charge the battery once when the depth of discharge is 60%—70%. In actual use, it can be converted into a cruising range, and the necessary charging should be carried out according to the actual situation to avoid harmful charging.
Do not discharge with high current
Try to avoid long-time high current discharge. High-current discharge can easily lead to the crystallization of lead sulfate, thereby damaging the physical properties of the battery plate.
Prevent high-temperature exposure
The electric sightseeing car is strictly prohibited from being exposed to sunlight. An over-temperature environment will increase the internal pressure of the battery and the battery pressure limiting valve will be forced to open automatically. The direct consequence is to increase the battery's water loss. Excessive loss of water in the battery of an electric sightseeing car will inevitably lead to a decrease in battery activity and accelerate the softening of the plate. Fatal injuries such as heat generation, bulging and deformation of the housing during charging.
