Reasons for shorter mileage of Electric Sightseeing Car

Many times, users will find that as the use time increases, Electric Sightseeing Car have a problem with short mileage. The main reason is that there is a problem with the battery. The following editor will explain the reasons in detail:

1. Self-discharge

The phenomenon that a fully charged battery is left unused and gradually loses power is called self-discharge. Self-discharge of Electric Sightseeing Car is inevitable. Under normal circumstances, the daily discharge rate should not exceed.

2. Shell cracks or sealing glue ruptures

Cracks will cause the electrolyte to leak out, resulting in a lower liquid level. If there are fine cracks on the internal wall, the two single-cell batteries are connected, causing the voltage to drop. Blockage of the vents will prevent the gas from being released, causing excessive pressure in the single cell; winter freezing cracks, excessive vibration of Electric Sightseeing Car during driving, etc. will cause cracks in the shell.

3. Shedding of active materials on the plate

During normal use and charging of Sightseeing Bus batteries, the volume of the active materials on the plate continues to expand and shrink, which will cause the active materials to slowly fall off. If used improperly, the active materials will fall off rapidly and in large quantities, causing a short circuit on the plate. The main reason for the active material of the plate to fall off is excessive current or high temperature during charging. Frequent overcharging, etc. During discharge, excessive current will cause the active material to fall off.

4. Plate sulfidation

That is, white coarse grains of lead sulfate are gradually generated on the surface of the plate. This kind of grain is hard and difficult to dissolve in the electrolyte. It is not easy to react with the electrolyte during charging, thereby reducing the active material. In addition, coarse grains of lead sulfate block the pores of the plate, making it difficult for the electrolyte to penetrate, and increasing the internal resistance, which reduces the active material participating in the reaction in the plate, resulting in a decrease in the capacity of the Sightseeing Bus.
