This is a 4S 1P battery pack, but if we want, we can connect higher-capacity cells or cells in parallel. Therefore, we can use the same BMS to make a 4s 2P battery pack or a 4s 3P battery pack, etc. This BMS comes in 3 variants, the standard version, the enhanced version, and the balanced version. We will be looking at the Balanced version.
The electrical path to pull up the battery pack VCC passes through the host capacitance from Pack+ to Pack–, through a substrate diode in the host interface driver from VSS to the commu-nication or interface line, and through a substrate diode from this line to VCC in the battery-pack circuitry. The complete path is shown in Fig. 6.
