6 FAQs about [New energy battery arrangement and positioning]

How are battery energy storage systems optimized?

Why does a battery have a rectangular arrangement?

This is because the rectangular arrangement at position a hinders the deep penetration of air into the battery, resulting in less heat dissipation by the airflow, and consequently leading to higher temperatures in the middle and rear positions. Figure 11.

How a power battery affects the development of NEVS?

How does a staggered battery arrangement affect heat dissipation performance?

The staggered arrangement has a greater impact on the heat dissipation performance of the battery pack, but the spacing between different modules varies with the position of the modules. When all configuration schemes are staggered modules, the optimal range of the spacing between modules is between 6 and 7 mm.

Where should a battery pack be placed?

Placement: The battery pack should be placed as close as possible to the ground, to lower the center of gravity of the vehicle and thus not affect its dynamic riding performances. The battery placement is also crucial to determine the vehicle packaging and the vehicle’s occupant ergonomics.

How does the location of the battery pack affect drivability?

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.
