How wavy cold plate reduce cell temperature in battery pack?

Four new designs wavy cold plates along with simple hybrid cooling system proposed to reduce cell temperatures in battery pack. The optimised wavy cold plate offer efficient cool and warm-up performance. Prominent solution for cell temperature uniformity with all proposed designs.

How hot does a battery pack get?

From the results, optimised model effectively increases the cell temperatures in the battery pack from 4 ° C to 16 ° C within 600 s. Whereas remaining models such as core, extended fin and ripple models shows battery pack temperatures as 12.5 ° C, 13 ° C and 12 ° C respectively within 600 s.

What is a large cooling channel wavy cold plate battery pack?

Larger cooling channel size is capable of decreasing the maximum temperature and improve cooling energy efficiency of the large cooling channel wavy cold plate battery pack with reduced cell temperatures, which further achieve temperature uniformity of cells in a battery pack.

Does the battery pack need to warm-up during winter?

During winter conditions, the battery pack in a vehicle needs to warm-up in order to avoid problems while starting the vehicle. The warm-up performance was investigated by the proposed thermal models. The proposed hybrid cooling system aims to protect the battery pack in extreme cold weather conditions.
