The Li-ion battery pack circuit diagram consists of three basic components: the battery cells, the PCM, and the load. The cells are the primary energy source for the system, providing the energy for the load. The PCM is responsible for monitoring and protecting the battery from overcharging, over-discharging, and excessive temperature.
A battery parallel assembly comprises multiple battery cells connected electrically in parallel under a specific topological configuration or geometrical arrangement. In this example, you create a parallel assembly of four cylindrical cells stacked in a square topology over four rows.
In each of the examples, the 4 batteries are identified as A, B, C, and D. Example 1, shown in Figure 4, has 2 pairs of series connected batteries joined in a single parallel connection.
