A battery pack for EVs consists of many battery cells that connected series and parallel. When a single cell catches fire or explodes, a “domino effect” will be triggered and propagate through the entire battery pack , posing a huge threat to the vehicle and the personal safety of passengers.
Most battery chemistries allow parallel configurations with little side effect. Figure 4: Parallel connection of four cells (4p). With parallel cells, capacity in Ah and runtime increases while the voltage stays the same.
If higher currents are needed and larger cells are not available or do not fit the design constraint, one or more cells can be connected in parallel. Most battery chemistries allow parallel configurations with little side effect. Figure 4: Parallel connection of four cells (4p).
Parallel connection attains higher capacity by adding up the total ampere-hour (Ah). Some packs may consist of a combination of series and parallel connections. Laptop batteries commonly have four 3.6V Li-ion cells in series to achieve a nominal voltage 14.4V and two in parallel to boost the capacity from 2,400mAh to 4,800mAh.
This combination of cells is called a battery. Sometimes battery packs are used in both configurations together to get the desired voltage and high capacity. This configuration is found in the laptop battery, which has four Li-ion cells of 3.6 V connected in series to get 14.4 V.
Such a configuration is called 4s2p, meaning four cells in series and two in parallel. Insulating foil between the cells prevents the conductive metallic skin from causing an electrical short. Most battery chemistries lend themselves to series and parallel connection.
