A precharge circuit limits that inrush current, without limiting the operating current. Typical precharge circuit. In the typical precharge circuit, the precharge resistor is on the positive terminal of the battery, though it could just as easily be on the negative terminal.
During the pre-charging process, the following reactions will occur inside the lithium battery: the active material is activated, the positive electrode material releases lithium ions, enters the electrolyte, penetrates the separator, enters the electrolyte, and is finally embedded in the layered gaps of the negative electrode material.
Pre-charging can slowly increase the voltage by applying a smaller current, thereby reducing the inrush current and helping to protect the battery. Extended battery life: Pre-charging allows the battery to charge more slowly and evenly, which is especially important early in the battery's life.
