6 FAQs about [Battery System Heat Dissipation]

How does a battery heat build up and dissipate?

Battery heat builds up quickly, dissipates slowly, and rises swiftly in the early stages of discharge, when the temperature is close to that of the surrounding air. Once the battery has been depleted for some time, the heat generation and dissipation capabilities are about equal, and the battery’s temperature rise becomes gradual.

How does a lower inlet temperature affect battery heat dissipation?

An increased heat exchange rate is more beneficial to the battery heat dissipation. Although a lower inlet temperature can increase the heat dissipation, the parasitic energy consumption needed by the cooling water in the refrigeration system would be higher, which needs further to be balanced.
