How to fix the UPS lithium-ion battery? How to repair the UPS lithium-ion battery is the correct way? We will always encounter some technical problems during the process of using the UPS lithium-ion battery, such as lithium ion batteries. The UPS power is faulty, can't open the machine, etc. .

At this time, it is necessary to fix the lithium ion battery UPS. Here is some of the previous UPS battery repair related experience in Xiaobian for reference. How to repair the UPS lithium ion battery? Repair method 1 - Detection UPS lithium ion battery first detects the working state of the lithium ion battery on the UPS, detail the floating voltage of each lithium ion battery.

Its important related experience is that the battery should be in each single voltage of 2.25V, that is, the voltage of the 12V battery should be strict 13.5V.

If it is lower than this voltage, it is necessary to suspect whether the battery has undermountable phenomenon. If the battery voltage is higher than this voltage, it is necessary to suspect whether the battery has lost water. If the 48V lithium ion battery is used in series, the installation of single-handed battery voltage 2.

25V is calculated, it should be 54V. Below this voltage, the battery is under charging, higher than this voltage, battery is lost. Fixing Method 2 - A group of repaired lithium-ion batteries, saves 1 day, measure its open circuit voltage.

Communicate according to the open circuit voltage of the UPS lithium ion battery and the capacity of the battery. Ask the battery's open circuit voltage error no more than 0.03V, the battery capacity difference is not more than 10%.

In this way, a part of a battery and voltage deviation is required. Also remove the battery with large voltage deviation. There is also a battery with a capacity of less than 70%.

Repair Method 3 - Maintaining the UPS battery about the repair, is generally hosted by a battery pulse protector to a lithium ion battery so that the battery will never vulcanize. The method for the UPS battery distribution protector is to hang a protector every 12V battery. And every 3 months is performed, and the battery-low battery is removed, and the battery is separately charged and discharge and pulse repair.

In this way, it can generally increase the battery life from 1 to 4 years. Repair method 4 - Maintaining a suitable temperature to ensure that the UPS battery is running on a general UPS lithium-ion battery, which should ensure that the temperature of its environment is between 20 and 25 degrees Celsius, and the temperature increases simultaneously results in battery life. Decrease.

In addition, if the external ambient temperature is too high, it will increase the internal chemical reaction speed of the battery. In turn, it will promote the speed of environmental temperature, and this loop reciprocating vicious circle will rapidly speed up the depreciation of the battery. Thus affecting normal use.

Repair method 5 - Timely replacement of waste / bad lithium ion batteries in a continuous operation of lithium-ion battery UPS, due to performance and quality, individual battery performance is lowered, and the storage capacity does not meet the requirements and is damaged. When a certain / some batteries in the battery pack, the maintenance personnel should check each battery to exclude damaged batteries. The UPS lithium-ion battery has life expectancy, and the correct repair and usage can be more effective in extending the service life of lithium-ion battery UPS power supply, reducing battery loss, saving funds.

I hope that the above content can help everyone, there are different opinions and opinions, and the small series will come to exchange discussion.
