Research on Test Method for Low-Temperature Performance Consistency of Power Battery Pack

Under low temperature condition, the inconsistency that the internal resistance of the battery due to the influence of processing and manufacturing processes can't be effectively tested at constant temperature, therefore, this paper proposes a method for test of the electric performance consistence of the lithium-ion batteries at low temperature, this method can test the electric performance consistency of the lithium-ion batteries at low temperature, effectively solve the problem of cells that have good electric performance consistency under normal temperature condition, but have considerably different electric performance under low temperature condition.
