What are the misunderstandings in the maintenance of electric pallet truck batteries?
The battery of the electric pallet truck is provided as a kind of power engineering that can work independently, and is widely used in a variety of manufacturing industries. The UPS power supply of the big data center, the communication power supply of the electric power enterprise, the electric pallet truck and the power supply of the car in the urban rail and the reserve switching power supply of the subway entrance, all show the application of key electric energy for continuous operation. Like other mechanical equipment, batteries also need regular maintenance. However, many technical engineers do not have rich and colorful work experience in these areas, and there are still some misunderstandings regarding new maintenance projects and maintenance methods. What is the misunderstanding of the maintenance of the battery of the electric pallet truck? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some relevant information on this issue. I hope it will be helpful to you. In the future, you can avoid detours when using and purchasing.
1. Maintenance of the battery of the electric pallet truck only needs to monitor the working voltage
Because of the cost factor, some technical engineers usually use digital multimeters to detect the floating voltage of rechargeable batteries. At this stage, online systems currently on the market also monitor and evaluate the physical and mental health of rechargeable batteries or power batteries based on the operating voltage of rechargeable batteries. Happening. However, the floating charge working voltage only reflects whether the charging head is working normally, but not the physical condition of the rechargeable battery. When the battery power drops, the floating charge operating voltage is likely to remain too high because of the manipulation of the UPS battery charger. This is why sometimes the UPS operating voltage display information is normal, but after a power failure, the lithium battery pack is quickly cut off and cannot be charged and discharged.
The open circuit voltage of the rechargeable battery (the working voltage after the battery charger is disconnected) can partly reflect the capacity of the rechargeable battery. However, only when the battery power is severely reduced, the open circuit voltage will change significantly. The internal resistance of the battery changes much faster. In the middle and early stages of volume reduction, the internal resistance will have a unique rise. Therefore, the internal resistance detects the deterioration of the rechargeable battery earlier than the operating voltage.
It is not easy to change the working voltage of the floating charge in the early and mid-to-late stages of battery deterioration of electric trucks. It is not easy to find the problem according to the working voltage inspection until the rechargeable battery leads or short-circuits the fault or the deterioration is serious, but it may not help. .
2, ‘maintenance-free lead-acid battery’ does not require maintenance
To put it plainly, "maintenance-free" means that it is not necessary to add lithium battery electrolyte or purified water on time, and it does not require regular maintenance of its "physical condition".
If this kind of maintenance-free battery is not regularly maintained, it is very easy to deteriorate and become invalid. In rare cases, liquid leakage and erosion, internal short-circuit failures, and serious cases will cause part of the fire to cause fire accidents.
