18650 battery heat treatment scheme.
18650 battery heat treatment scheme：
Because tesla use 18650 battery, and its cooling scheme is also improved and attempt taken by different factories.
Aiming at this situation, we utilize the cylinder characteristic of pipe, between battery cells there is space that can hold a pipe of φ6.5-φ8, the heat pipe could be put inside, and use the heat radiation of heat pipe as heating unit of batteries, by practical test, the result met expectation.
Such design, no matter 4 cell or 3 cells packed together both can achieve the middle inside heat release, and without reducing the energy density. Just take full advantage of space inside the model. Its principle is heat pipe can absorb heat radiation and transfer heat well, such design has been applied for a patent.
