The battery of the children's electric car is the power source of the electric car, so how should we maintain the battery of the children's electric car? Today, I will share with you the maintenance knowledge of children's electric car batteries.

 common sense of maintenance of children's electric car battery:

We must not lose electricity after using children's electric vehicles. The state of loss of electricity means that the battery is not charged in time after use, and it is prone to sulfation. Lead sulfate crystals are attached to the plate, blocking the ion channel, causing insufficient charging and reducing 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.

We need to regularly check whether there is no power supply or short circuit during use. It is very likely that at least one battery in the battery pack has short-circuit phenomena such as broken grids, softening of the plates, and loss of active materials on the plates. At this time, you should go to a professional battery repair organization for inspection, repair or assembly in time. When starting or going uphill, the electric children's vehicle should try to avoid instantaneous high current discharge. High-current discharge can easily lead to the crystallization of lead sulfate, thereby damaging the physical properties of the battery plate.

Master the charging time. Generally, the battery is charged at night, and the average charging time is about 8 hours. If it is a shallow discharge (the mileage is short after charging), the battery will be fully charged soon, and overcharge will occur if the battery continues to charge, 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 riding mileage, and necessary charging is carried out according to the actual situation to avoid harmful charging.

Prevent high-temperature exposure Electric vehicles are 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 battery loss will inevitably lead to a decrease in battery activity, accelerate the softening of the plate, and the shell during charging. Fatal injuries such as body heat, bulging of the shell, deformation, etc. Most of these batteries are of average quality, and some even show a significant decrease in capacity after two or three months of use. Generally speaking, the battery should be charged frequently to avoid deep discharge and high current discharge. For this kind of battery car, it is necessary to fully charge it every time it is used up, try not to use a bit of electricity without recharging it, and do not force it to start when it is difficult to start the electric car.
