At a first glance, discussing the body, chassis, and its associated systems may not seem relevant to electric vehicles (EVs) and hybrid electric vehicles (HEVs) because the primary differences between these vehicles and conventional internal combustion engine vehicles (ICEV's) relate to their powertrain systems. However, there are numerous challenges associated with the body, chassis, and chassis systems of electric and hybrid electric vehicles that should be noted separately.
One of the main challenges is optimizing energy consumption for EVs and HEVs, which have limited on-board energy. As such, constructing lightweight body, chassis, and chassis systems should be a primary focus of the design process. Likewise, accommodating a heavy and oversized battery pack into the chassis and body design is another challenge. For these reasons, it is important to study the design and technology behind the body, chassis, and chassis systems.
This chapter has two main objectives:
In order to achieve these objectives, this chapter addresses body chassis and chassis systems in the following sections discussing both general and specific information regarding EVs and HEVs.
As illustrated in Figure 3.1, a car can be divided into two main parts: ...
