“Prismatic cans are best suited for cell-to-pack and cell-to-chassis battery designs owing to the presence of both electrical terminals on the top of the cell, allowing for access to make the electrical connections to build up the voltage and battery as well as installing and connecting the battery management system [BMS],” he says.
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.
The range that you want for your EV determines the final size of the battery pack. Therefore you need to decide on the theoretical range you will need in order to convert this to the capacity in kWh. This is a key requirement to keep in mind when designing the battery pack.
