What causes the battery capacity of electric pallet trucks to decrease

Electric pallet trucks mainly rely on batteries as a power source for driving operations. The decrease in battery capacity of electric pallet trucks will directly affect the use time of the pallet truck. What causes the decrease in battery capacity of electric pallet trucks?

1. The battery storage time is too long

The battery of the small electric pallet truck manufacturer cannot be installed and applied immediately after arriving at the customer's original factory, resulting in long-term storage. Long-term storage will inevitably lead to insufficient capacity of lithium battery life. Because the long-term storage of the battery is wrong, it needs to be charged at intervals.

2. The positive plate of the forklift battery is corroded, and the deformation causes insufficient volume

The positive plate of the forklift battery is a key element that endangers the service life of the rechargeable battery. The volume of the battery charging cycle system, especially the volume reduction under deep cycle, is closely related to the quality error of the positive electrode sheet.

3. The active material on the positive electrode grid becomes soft and falls off

There are holes and micro-plates in the external economically active substances. The size of the holes is more than 0.5 cm. It is composed of many small round holes. With the development of the charge-discharge cycle system, the surface of the specific substances is gathered, and the key is formed into coral. Cluster-like structure, the use of small round holes in the charging and discharging cycle system for several times increases, so that the holes continue to rise, destroying the positive structure and causing specific objects to fall.

The key reason for this situation is that the forklift battery is charged with a large current of battery. Prevents the amount of current that should ensure battery charging and prevents overcharging or undercharging.

4. Erosion deformation of positive grid

The corrosion rate of the grid depends on the composition of the grid aluminum alloy, but the higher the storage temperature, the faster the corrosion rate, the heavier the charge and discharge depth, and the more serious the corrosion.

5. Potassium thiocyanate of electric truck battery negative plate

When everything is working normally, the PbSO4 particles on the negative plate are small, and it is very easy to be repaired into velvety lead when charging and discharging.

There are many reasons for the negative-level salt industry, such as the battery cannot be charged immediately after charging and discharging, the rechargeable battery is idle for a long time, resulting in a serious lithium battery life, the lithium battery electrolyte concentration is too high, the long-term battery is not charged enough, and the high temperature Long-term charge and discharge, this kind of lead sulfate cannot be restored by basic methods, so the reduction of active substances will inevitably endanger the capacity of the lithium pallet truck battery.

The above are the reasons that lead to the decline of the battery capacity of electric pallet trucks. I hope everyone can pay attention, use electric trucks correctly and reasonably, do a good job in battery charging and maintenance, and reduce the occurrence of battery failures in trucks.
