Electric forklift battery charging basic essentials


Release time:

Jul 06,2021

Electric forklift operation control is simple, flexible, operating intensity relative to the internal combustion forklift much lighter, its electric steering system, acceleration control system, hydraulic control system and brake system are controlled by electrical signals, greatly reducing the labor intensity of the operator, for improving work efficiency and accuracy of work is very helpful. In addition, the electric forklift has short downtime and low maintenance costs.

In addition, the electric forklift has short downtime and low maintenance costs.

The motor used in the previous electric forklift was an ancient and traditional series DC motor. It is to deliver power to the battery and turn it dry. However, this kind of motor has two defects: this current is transmitted by carbon brushes, so its performance is determined by the carbon brushes, which limits the braking performance. Moreover, the carbon brush is a vulnerable part and needs to be replaced regularly, otherwise it will affect the life of the motor.

Electric forklift can be used more and more widely in the field of application, and become an indispensable means of transportation in the professional field. With the extensive use of electric forklift and electric stacker, we can see the rapid development of electric technology in today's era.

Electric forklift battery belongs to an electric energy transfer For a system with mechanical energy, when the power output is used up, it needs to be supplemented with current, otherwise the battery will have no effect, and shelving will also cause the active material of the battery to fall off. The normal charging current should form a certain proportion with the forklift battery, for example: 48V400AH, with 0.14 times of the capacity, can meet the basic requirements. If the current value is exceeded, the battery electrolyte will be overcharged and volatilize too fast. Once peculiar smell, then the plate of the forklift battery is out of powder, and overcharging will quickly reduce the capacity.

In order to avoid the impact on the forklift battery, we must learn the correct charging method, which can be done as follows: the current on the plate is evenly distributed, the resistance is small, and to reduce the loss of charging current. The thickness and porosity of the active material on the positive electrode of the battery. If the active material has a large porosity and the plate is thin, which is beneficial to the diffusion of the electrolyte, the polarization effect is reduced. Depth of discharge.

The deeper the depth of discharge, the positive active material Pbo: and the negative active material Pb All of them are greatly reduced, and the substances that need to be converted through charging increase, that is, there are more products participating in the reaction during charging, thus improving the charging acceptance. We do not recommend that the charger be adjusted to a larger size, and the water flows long. Everyone knows that rapid charging is very harmful to electric forklift batteries.
