As of 2021, the ownership of new energy vehicles in China reached 7.84 million units, accounting for 2.6% of the total number of vehicles, registering an increase of 59.25% over 2020. %, of which the ownership of battery electric vehicles (BEVs) had reached 6.4 million units by the end of 2021 .
Another important contribution comes from the sandwich structure, which is constituted by the passenger compartment floor and the underbody shield; sometimes, but not in all the existing solutions, the battery pack structure gives a contribution (see Figure 2) through specific structural components that are part of the battery case.
The location of the battery pack on board of the vehicle may affect the position of the vehicle center of gravity, which in turn could affect the vehicle’s drivability. In order to lower the possible negative consequences, the battery housing is generally located below the passengers compartment floor.
The possible consequences on the position of the vehicle center of gravity, which in turn could affect the vehicle drivability, lead to locate the battery housing below the passenger compartment floor.
