When connecting lithium iron phosphate batteries and lithium iron phosphate batteries in parallel, it is important to note that the capacity and voltage of the two batteries must match. If the capacity of two batteries is different, the current will be unevenly distributed between the two batteries, which may cause the voltage of the smaller capacity battery to be too low, thereby affecting the lifespan of the entire battery pack.
When lithium iron phosphate batteries and lithium iron phosphate batteries are connected in parallel, a battery management system (BMS) is required to balance the discharge current of the two batteries. BMS can ensure that small capacity batteries are not excessively discharged, thereby extending the lifespan of the entire battery pack.
In addition, appropriate protective equipment needs to be selected to protect the battery pack. For example, in each battery pack, overvoltage protection, undervoltage protection, and over temperature protection devices need to be installed to avoid safety issues caused by battery failures.
The selection of lithium connecting wires also requires special attention when batteries are connected in parallel. It is necessary to choose appropriate connecting wires to ensure even transmission and distribution of current. In addition, it is necessary to pay attention to the conductivity and heat dissipation of the wire, choose appropriate wire diameter and length to reduce line resistance and improve the efficiency of the battery pack.
When connecting batteries in parallel, it is necessary to place both battery positions steadily to ensure simultaneous discharge. If one battery is discharged while the other battery is not discharged, there will be unequal capacity. If this state is maintained for a long time, it will cause a decrease in the lifespan of the battery pack.
In summary, lifepo4 batteries and lithium iron phosphate batteries can be connected in parallel, but attention should be paid to capacity and voltage matching, discharge balance and protection, selection of appropriate connection wires and placement methods, and other precautions. I hope the introduction in this article can be helpful to you.
