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.
So, for two 1.5V batteries in parallel, the voltage remains 1.5V, while the capacity doubles. Understand the role of capacity constants like milliamp-hours (mAh). They quantify the energy storage in batteries. Larger mAh means more energy, longer life before recharge or replacement is necessary.
The number of cells in parallel will effect the pack voltage under load, but that is a different calculation. The graduated cells plotted versus series and parallel give the total pack size in kWh.
