As outlined in a previous chapter, it may be necessary to provide a peak power of, for example, 100 kW for electric vehicles (EVs). The term high voltage is defined for DC voltages above 60 V and AC voltages above 30 V (ISO 6469-3, 2011). The reason for using high voltages in a battery pack comes from the basic law of physics: (10.1) P = V ⋅ I
Battery Cells: A high-voltage battery consists of multiple cells connected in series. Each cell generates a small amount of voltage, and the total voltage increases by linking them. For example, three 3.7V cells in a series create an 11.1V battery. Power Delivery: The stored energy flows through the device’s circuit when the battery is used.
HV battery packs for battery electric vehicles (BEVs) are characterized by high energy densities and high energy contents with low power densities. Figure 10.1 shows a schematic illustration of a battery pack and its components, which are necessary to fulfill the vehicle requirements. Figure 10.1.
As for PHEVs and especially BEVs the battery pack accounts for the biggest part of the weight of the whole vehicle, the battery housing is designed in strong interaction with the design of the body of the car.
Higher-capacity batteries can store more energy and provide power for a longer period before recharging. Battery cells can be arranged to increase voltage or capacity. Series connections are commonly used in electric vehicles (EVs) and other applications requiring higher voltage levels.
