Electric forklifts often encounter abnormal voltages in lead-acid batteries during operation, so what are the causes and solutions? The following electric forklift manufacturers will share the relevant methods.
First of all, we must understand that there are two phenomena of abnormal battery voltage. One is when the battery is charging, the voltage is high, and the voltage drops quickly during discharge. The other is that the battery is in use, and the voltage drops significantly.
1. When charging an electric forklift lead-acid battery, what is the reason why the voltage is high and the voltage drops quickly during discharge? Mainly sulphation of polar plates.
Solution: According to the degree of sulfate, adjust the electro-hydraulic concentration, electro-hydraulic composition, charging current and other methods to eliminate the acidification of the polar plate.
2. What is the reason why the voltage drops significantly during battery use? The main reason is that the pole of a single cell of the battery is reversed, the pole group of the entire battery is reversed, the capacity of a single battery is low or there is a short circuit.
Solution: According to the arrangement of the battery pack, it can be eliminated by checking the voltage of the single battery, whether the pole of the single battery is consistent with the group, and whether the battery group is in good condition.
The above is the failure analysis of the voltage abnormality of the lead-acid battery of the electric forklift. In short, when the voltage is abnormal, the inspection work needs to be done to solve the failure in time, and the daily maintenance of the battery must also be done.
