Protection Circuit Module (PCM)
The Cell(s) / Battery Pack shall be used with a PCM which can protect Cell(s) / Battery Pack properly.
The PCM shall have functions of (a) overcharging protection;(b) over-discharging protection and (c)
over current protection, to maintain safety and significant deterioration of cell performance. The over
current can occur by external short circuit.
a. Overcharging prohibition
- Overcharging prevention function shall work if any one of the cell of the battery reaches
4.25V or above which charging should be stopped.
b. Overdischarge prohibition
- Overdischarging prevention function shall work if the Cell(S) / Battery Pack reaches
below 2.50V.
- It is recommended that the dissipation current of PCM shall be designed to minimal
such as 0.5 microamperes or less after the over-discharge prevention function works.
- The protection function shall monitor each cell for controlling the current throughout
the time.
Design of Protection Circuit Module(PCM)
a. PCM shall be located away from the gas-release vent of the cell as much as possible.
b. Circuit pattern of PCM shall be away from each other as much as possible.
