4 FAQs about [Pakc-level energy storage]

Can a passive cooling system be used in a battery pack?

Due to these advantages, this passive cooling system has been tested in battery packs for electric vehicles . Despite those promising features, heat pipes are still in development phase and considerable optimization work remains to improve the cooling performance of this technology .

Can a pack cycle maintain cell temperature distribution uniformly?

By analyzing the obtained results on pack level, as expected the pack cycled under immersed cooling (Pack N) can maintain the cell temperature distribution rather uniformly, with a deviation between maximum and minim cell temperature of approx. 1.4–1.5 °C.

What are the 6 layers of protection inside a battery pack?

These 6 layers of protection inside each battery pack redefine system safety： Smoke sensor, full-coverage temp. detection, high-temp. resistant insulated pad, insulation and heat isolation layer, a decompression valve and a fire extinguishing kit.

How does pack degradation affect the spread of cell capacity?

Therefore, the pack degradation at the end of the test results in wider spread of capacity between all cells. In fact, considering the beginning of test, in comparison with Pack N, the deviation between the maximum and minimum capacity is factor three smaller (0.051 Ah against 0.148 Ah).
