Now lithium ion battery is becoming more and more popular in the energy storage market. It has the advantages of small size, lightweight, and high energy density. Therefore, I have many clients who use 48V lithium ion battery 100Ah in their solar projects.

Now let me share some knowledge of lithium ion battery

1, How to assemble into 48V lithium ion battery 100Ah

Single-cell is 3.2V100Ah, then we can use 15 cells in series to form 48V 100Ah

2, How to extend the service life of  lithium ion battery

First, do not overcharge or over-discharge the battery. If overcharged, the capacity of the battery will be permanently damaged. If continue overcharged, there is a danger of explosion. If over-discharged, the battery will never be charged, so it needs to be opened for special activation, So we need to set the depth of discharge for the battery.
Second, control the temperature when the battery is is best to use it at room temperature. Too high or too low temperature will affect the battery life.
Third, don’t charge the battery with a high current. Too high charging current will also affect battery life

3, Principle and function of lithium ion battery BMS

If lithium ion battery is short-circuited, it is very dangerous. A short circuit causes the battery to generate a very high current, At the same time, it will also produce very high heat, Seriously affect the life of the battery, and even explode. Therefore, when the lithium ion battery is installed with BMS. When there is a large current, the BMS will be turned off instantly, so that the battery will be powered off, and no heat will be generated.
Therefore, the functions of the BMS are: Overcharge protection, over-discharge protection, short circuit protection, high current protection, temperature control, switch function, etc.

4, How to set the working voltage and cut off protection voltage for 48V lithium ion battery 100Ah

Single-cell working voltage is 2.8 to 3.5V, Charging voltage 3.7V. when DOD is 80%, The voltage is about 3V. So for the 48V lithium ion battery, The working voltage is 42V to 52.5V, the Charging voltage is 55.5V, Cut off voltage is 45V. This will extend the life of the battery.
