Fault analysis of abnormal voltage of lead-acid battery of electric forklift

Electric forklifts often encounter abnormal lead-acid battery voltage during operation. What are the reasons for this phenomenon and what are the solutions? The following electric forklift manufacturers will share the relevant methods. First of all, it is necessary to understand that there are two phenomena of abnormal battery voltage. One is that when the battery is charging, the voltage is too high, and the voltage drops quickly when discharging. The other is that the voltage of the battery is significantly reduced during use. 1. When the lead-acid battery of the electric forklift is charged, what is the reason for the high voltage and the rapid decrease of the voltage when discharging? Mainly plate sulfation. Solution: According to the degree of sulfation, the acidification of the electrode plate can be eliminated by adjusting the electro-hydraulic concentration, electro-hydraulic composition, charging current and other methods. 2. What is the reason why the voltage of the battery drops significantly during use? It is mainly due to the reverse connection of a single cell of the battery, the reverse connection of the entire battery pack, the low capacity of a single battery or a short circuit. Solution: According to the arrangement of the battery group, check whether the voltage of the single battery, whether the pole of the single battery is consistent with the group, and whether the connection of the battery group is in good condition, etc. are eliminated. The above is the fault analysis of the abnormal voltage of the lead-acid battery of the electric forklift. In short, when encountering the abnormal voltage, it is necessary to do a good job of inspection, solve the fault in time, and do a good job in the daily maintenance of the battery.
