How To Store And Maintain 48v Lithium Iron Phosphate Battery Pack?

Lithium battery packs can be stored for more than half a year at temperatures below 20°C. This is due to the low self-discharge rate of the battery packs and the fact that most of the capacity can be recovered. Long-term non-use of lithium iron phosphate batteries should be charged to 90%, placed in a dry place, it is best to pack, do not let the positive and negative poles of the battery come into contact with metal objects, otherwise it will trigger a short circuit. Here we introduce how to store and maintain 48V lithium iron phosphate battery pack.

 

How to store 48V lithium iron phosphate battery pack?

You look at a set of data to know:  the percentage for the saturation state at the time relative to the initial value, measured data is the result of the battery pack after one year of storage.

Storage temperature 0 degrees Celsius, 40% state of charge 98%.

Storage temperature 25 degrees Celsius, 40% state of charge 96%.

40 degrees Celsius, 40% state of charge 85%.

Storage temperature 60 degrees Celsius, 40% state of charge 75%.

Storage Temperature 0 degrees,  100% state of charge 94%

Storage Temperature 25 degrees, 100% State of Charge 80%.

Storage Temperature 40 degrees, 100% State of Charge 65%.

Storage temperature 60 degrees, 100% state-of-charge 60%

 

It is recommended that the battery pack be charged to 40-50% and placed in a cool place with low temperature. If possible, it is best to take the 48V LiFePO4 battery pack out and use it once a month to ensure the battery is in a good storage condition, and not to let the battery lose its power completely and damage the battery.

 

How to save 48V lithium batteries?

1. Use the right battery

When replacing the battery, follow the battery model and size used in the machine, and replace it with the same battery model as far as possible.

2. Clean the positive and negative contacts

Since dust and dirt can affect the conductive effect, you need to occasionally clean the positive and negative metal contacts in the lithium iron phosphate battery pack slot.

3. Timely removal and replacement

When you see the prompt “low battery” need to charge in time, don't take off the discharged battery and put it aside for a long time without charging, which will cause the battery to be permanently damaged due to over-discharging; if the battery pack is put in the appliance for a longer period of time and no longer be used, it is best to take out the battery pack and put it in a low-temperature, dry place, otherwise, that is, the appliance is turned off, the system will still make the battery have a low current output, which will shorten the service life of the lithium battery pack. Otherwise, even if the appliance is turned off, the system will still make the battery have a low current output, which will shorten the service life of the lithium battery pack.

4. Low temperature use and storage

Try to avoid placing the lithium battery outdoors in extremely cold weather, pay attention to the temperature of the outside of the battery; the battery can be stored in a low-temperature environment to slow down the battery's own discharge rate, pay attention to avoid dew before use.

5. Prevent short circuit

Lithium battery pack outside the two ends connected to any conductor will cause a short circuit, the battery type is different, short circuit is likely to bring different severity of the consequences. Such as: the battery can not be used, leakage, explosion, etc. Do not put the battery into a humid environment, and can not be mixed with the conductor, such as the pocket at the same time into the key, the battery, both may cause a short circuit.

 

Lithium battery packs need to pay attention to several issues in the correct use:

1. Do not intentionally discharge when using 48V lithium battery packs, when the DC reminds you that the battery needs to be charged (power flashing), you should remove the battery to charge.

2. The charging process should be strictly in accordance with the standard implementation, the battery can be taken down after the power is full, do not need to charge for a few more hours, even if it is a new battery should be so.

3. The correct use of the battery is the best maintenance of lithium iron phosphate battery packs, when not in use for a long time, in the case of maintaining half of the power, find a dry, avoid direct sunlight place to save, and regular charging and discharging maintenance.
