The battery pack box of the target vehicle is arranged under the chassis, below the floor of the passenger compartment, disassembled from the electric vehicle. The appearance structure of the box is shown in Fig. 3. After removing the upper cover, the battery pack module is presented, and the structure is shown in Fig. 4.
The battery pack box is bolted to the chassis structure of the vehicle through the lifting lugs and fixed to the chassis of the vehicle. The internal structure of the battery pack box is shown in Fig. 8. The structure includes the upper-pressure rod, the upper-pressure cover, and the inner frame.
The packs’ primary components are the modules, often connected electrically in series and constructed by a set of cells. These cells can either be cylindrical, prismatic or pouch as illustrated in Figure 6. (4) The electrolyte used in the battery packs varies depending on what kind of cell that is employed.
Figure 10 shows the distribution of the stress nephogram of the battery pack box during the collision. The maximum stress value of the box is 335.5 MPa, and the maximum stress value of the lifting lug closest to the collision rigid column is 413.4 MPa.
The BMS and power relays can be found inside the pack whereas the DC-DC converter, HV controller and other HV units are mounted in other parts of the vehicle. Furthermore, the pack consist of ten modules, divided in two rows and two levels with the lower modules containing 30 cells and the upper modules 24.

Solution. We start by making a circuit diagram, as in Figure (PageIndex{7}), showing the resistors, the current, (I), the battery and the battery arrow.Note that since this is a closed circuit with only one path, the current through the battery, (I), is the same as the current through the two resistors. Figure (PageIndex{7}): Two resistors connected in series with a battery.
