The power battery is the only source of power for battery electric vehicles, and the safety of the battery pack box structure provides an important guarantee for the safe driving of battery electric vehicles. The battery pack box structure shall be of good shock resistance, impact resistance, and durability.
As a result, battery energy storage systems (BESSs) are becoming a primary energy storage system. The high-performance demand on these BESS can have severe negative effects on their internal operations such as heating and catching on fire when operating in overcharge or undercharge states.
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.
A series of temperature sensors are combined and distributed on the insulating plate according to the arrangement. A cooling fan is installed on one side of the box to meet the requirements of circulating heat dissipation inside the battery pack box. The battery pack box structure system is extremely complex.
The results show that after the structural optimization, the T max of the battery pack is 32.73 °C and the ΔT max is 4.15 °C. Comparing the temperature distribution of the heat sink system before optimization, the temperature uniformity of the battery pack has been greatly improved.
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.
