What are the different types of battery packs?

There are two basic types of battery packs: primary and secondary or rechargeable. Primary batteries are disposable, non-rechargeable devices. They must be replaced once their energy supply is depleted. Secondary or rechargeable batteries contain active materials that can be regenerated.

What are HV battery packs?

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.

What is a battery pack's voltage?

A battery pack's voltage is the sum of the individual cell voltages. For example, a battery pack containing six 1.5 V cells would be rated at 9 V. Manufacturers typically specify the battery's nominal voltage, although its actual discharge voltage can vary depending on the battery's charge and current.

What are the components of a battery pack?

The primary components of a battery pack are the battery modules. The battery modules contain the lithium-ion cells and are usually designed in such a way that their module terminal voltage is below 60 V, and hence they can be handled without additional and expensive safety precautions (see Section 10.2.1).

What is a battery pack?

A battery pack is a combination of cells connected in series and parallel for the desired operating voltage and current ratings. From: Journal of Traffic and Transportation Engineering (English Edition), 2020 You might find these chapters and articles relevant to this topic. Massimo Santarelli, ...

What is a high voltage battery?

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
