What are the misunderstandings in the maintenance of electric pallet batteries?
As a kind of electric engineering that can work independently, the battery of electric truck is widely used in various manufacturing industries. The ups power supply of the big data center, the communication power supply of the power enterprise, the electric power supply of the electric pallet trucks and their urban rails, and the reserve switching power supply of the subway entrance all show that the key power energy is suitable for continuous operation. Like other mechanical equipment, batteries also need to be maintained on time. However, many technical engineers do not have rich and varied work experience in these areas, and there are still some misunderstandings about the maintenance of new projects and maintenance methods. What is the misunderstanding of the maintenance of the battery of the electric van? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kang Lida Electronic Power Co., Ltd. introduces you to the relevant information on this issue. I hope it will be helpful to you. In the future, you can use less detours when purchasing.
1. Maintain the battery of the electric pallet truck only by monitoring the working voltage
Because of the cost factor, some technical engineers usually apply a digital multimeter to detect the floating charging working voltage of the rechargeable battery. At present, the online system currently on the market also monitors and evaluates the physical and mental health of the reserve rechargeable battery or power battery according to the working voltage of the rechargeable battery. Happening. However, the floating charging working voltage only reflects whether the charging head is in normal operation, but cannot reflect the physical condition of the rechargeable battery. When the battery power decreases, the floating charge operating voltage is likely to remain too high due to the manipulation of the UPS battery charger. This is why sometimes the working voltage of the UPS shows that the information is normal, but after the power is cut off, the lithium battery pack is quickly cut off and cannot be charged or discharged.
The open circuit voltage of the rechargeable battery (the working voltage after the battery charger is turned off) can partially reflect the volume of the rechargeable battery. However, only when the battery power is seriously reduced, the open circuit voltage will change greatly. The internal resistance of the battery changes much faster. In the middle and early stages of volume reduction, the internal resistance will rise uniquely. Therefore, the internal resistance is found to deteriorate earlier than the operating voltage.
The working voltage of the floating charge in the early and middle and late stages of the battery deterioration of the electric truck is not easy to change greatly. Until the rechargeable battery leads or shorts or the deterioration is very serious, the problem will be found based on the working voltage inspection, but it may not help .

2. "Maintenance-free lead-acid battery" does not require maintenance
Frankly speaking, "maintenance free" is relative to the traditional open rechargeable battery. It does not need to add lithium battery electrolyte or pure water on time, and it does not need to maintain its ‘physical condition’ regularly.
If there is no regular maintenance on this maintenance-free battery, it is very prone to deterioration and invalidity. In case of liquid leakage and internal short-circuit failure, it may cause some fires and cause fire accidents.
Zhengzhou Kanglida Electronic Power Co., Ltd. was established in 2000, specializing in the development, production and sales of four series of maintenance-free lead-acid batteries and their electronic chargers, such as 2V, 4V, 6V and 12V. Products are widely used in anti-theft alarm systems, fire alarm systems, building intercom systems, elevator emergency evacuation systems, emergency lights, attendance machines, sprayers, electronic scales, children's electric motorcycles, cartoon gas models, car washers, table turntables, parking locks, Strobe lights, traffic command lights, DC screens, solar energy, wind energy, UPS, EPS and other backup power systems. If you choose a company, you must choose a company with a reliable reputation and quality. This company is a company that has been in business for many years. Experienced companies, so if you have a need for this, you may wish to contact us, I believe it is a good choice.
