As a battery pack designer it is important to understand the cell in detail so that you can interface with it optimally. It is interesting to look at the Function of the Cell Can or Enclosure and to think about the relationship between the Mechanical, Electrical and Thermal design.
Battery pack configurations can be designed with several options, some of which are determined by the chemistry, cell type, desired voltage and capacity, and dimensional space constraints. The basic explanation is how the battery cells are physically connected in series and parallel to achieve the desired power of the pack.
A structural battery pack is designed to become a structural component of the EV. This approach can reduce the EV’s weight by removing duplicate structures between the pack and the vehicle structure, as the battery pack becomes part of the vehicle structure. This design can improve the EV’s overall performance and efficiency.
To calculate the gross battery pack size, multiply the total parallel capacity in ampere-hours (Ah) by the battery pack’s nominal voltage in volts (V). The result is in watt-hours (Wh). The diagram below shows the configuration of a battery module from the Audi Q8 e-tron 55.
Parallel Connection: Increases the battery pack’s capacity, essential for storing the energy required to achieve the desired range. To calculate the gross battery pack size, multiply the total parallel capacity in ampere-hours (Ah) by the battery pack’s nominal voltage in volts (V). The result is in watt-hours (Wh).
When you think about designing a battery pack for electric vehicles you think at cell, module, BMS and pack level. However, you need to also rapidly think in terms of: electrical, thermal, mechanical, control and safety. Looking at the problem from different angles will help to ensure you don’t miss a critical element.
Battery Pack & Configuration
In an electric vehicle (EV), the battery configuration refers to the arrangement of individual battery cells within the battery pack. This configuration affects the voltage, capacity, power output, and overall vehicle performance. The most common configuration for EV batteries is a series-parallel hybrid.
