How does a battery design affect heat dissipation?
The design intent is to keep the package changes to the minimum but with better cooling efficiency. The results show that the locations and shapes of inlets and outlets have significant impact on the battery heat dissipation. A design is proposed to minimize the temperature variation among all battery cells.
Does air cooling improve the heat dissipation of a battery pack?
