Why does the battery of electric forklift truck vulcanize? How to avoid it?

The battery is an important part of the electric forklift truck. It can convert chemical energy into electrical energy to supply power to the electric forklift truck. Its working principle can be explained by bipolar sulfation theory. When the battery is discharged, the active materials of the positive and negative electrodes become lead sulfate (pbs04), and after charging, they return to the original state, that is, the positive electrode is changed into lead dioxide (PB02), and the negative electrode is changed into sponge lead (PB). However, due to various reasons, if the lead sulfate does not return to its original state, it will form and accumulate lead sulfate crystals on the negative plate of the battery, which is what we call "sulfurization". So, why does the battery of the electric forklift truck appear vulcanized? How to avoid it? Let's have a detailed answer from the electric forklift manufacturer.

The reasons for sulfurization of the battery of the electric forklift truck may be as follows: the battery has been put aside for a long time and has not been charged in time; The electrolyte concentration in the battery is too high, and lead sulfate is difficult to dissolve; Long term over discharge or low current deep discharge of battery; The battery is not charged enough, the battery is not floating charged or the constant voltage of the charger is set too low; The electrolyte composition is impure, and there may be metal ions or other undesirable components; Large external temperature difference; The battery did not replenish water in time, and the electrolyte could not cover the battery plate, resulting in the deep oxidation of the plate in the air. The electric forklift manufacturer reminds that the above problems must be avoided, otherwise the consequences will be unimaginable.

How to avoid the sulfurization problem of battery of electric forklift truck? First of all, when purchasing the electric forklift truck, it is necessary to fully consider whether the battery capacity of the electric forklift truck meets the working requirements of the enterprise, and avoid frequent charging of the battery during use. Secondly, to avoid excessive discharge of the battery, charge it in time. If the battery needs to be stored for a long time, it should also be charged regularly. Furthermore, it is necessary to avoid incomplete charging of the battery. Incomplete charging will do great harm to the battery. Finally, always check the electrolyte level of the battery, and note that the electrolyte level must be higher than the electrode plate. At the same time, the electric forklift manufacturer reminded that the impurities should not enter the electrolyte.

If white hard crystals are found on the surface of the battery plate of the electric forklift truck, it means that the battery has been vulcanized and must be treated in a timely manner. If the problem is not solved in time, the battery performance will deteriorate rapidly, the battery life will be greatly shortened, and the normal operation of the electric forklift truck will be affected. The electric forklift manufacturer reminded that to avoid the occurrence of vulcanization, the driver should pay more attention to trivial matters at ordinary times.
