How to Maintain Lithium Iron Phosphate Batteries for Energy Storage Systems?

Summary

Proper maintenance of lithium iron phosphate batteries can extend their service life. This article will specifically introduce the precautions for maintaining lithium iron phosphate batteries.

the working principle of the lithium iron phosphate battery energy storage system

The role of lithium iron phosphate battery energy storage systems in microgrid energy storage involve power generation, transmission, distribution, and even terminal power users. 

On the power generation side, the energy storage system can participate in fast response frequency modulation services, increase the reserve capacity of the grid, and can provide continuous power supply to end-users with renewable energy such as wind and solar energy, and effectively overcome its shortcomings such as volatility and intermittent. 

By performing the following maintenance on the lithium iron phosphate battery, the service life of the lithium iron phosphate battery energy storage system can be greatly extended.

1. Maintain a suitable temperature

The temperature should not be too low or too high. If the UPS battery is used in an environment that is higher than the specified operating temperature, that is, 35°C or higher, the battery's power will continue to decrease, and the battery's power supply time will not be as long as usual. If the device is charged at such a temperature, the damage to the lithium iron phosphate battery will be even greater. Therefore, keeping the operating temperature as suitable as possible is a good way to extend the life of the lithium battery.

If you use a lithium iron phosphate battery in a low-temperature environment, that is, below 4°C, you will also find that the use time of the UPS battery is reduced, but it is different from the use in a high-temperature environment. Once the temperature rises, the molecules in the battery are heated and restore the previous power immediately.

2. The frequency of use must be in place

If you want to maximize the effectiveness of lithium iron phosphate batteries, you need to use it frequently to keep the electrons in the lithium battery in a flowing state. If you don't use the lithium battery often, please remember to complete a charging cycle for the lithium battery every month and do a power calibration, that is, deep discharge and deep charge once.

3. Avoid mixing with metal bodies

Do not mix lithium iron phosphate batteries with metal objects to prevent metal objects from touching the positive and negative electrodes of the battery, causing a short circuit, damaging the battery, or even causing danger.

4. Avoid contact with corrosive substances

Lithium iron phosphate batteries should be in a clean, dry and ventilated environment, avoid contact with corrosive substances, and keep away from fire and heat sources.
