Electrolyte re-injection system of battery cell battery pack battery pack which can re-inject electrolyte and re-injection method of electrolyte of electric car battery pack

摘要

An electrolyte re-injection system for a battery pack according to the present invention comprises a negative electrode plate, a positive electrode plate, and a storage case for storing an electrode assembly which has a separator interposed between the negative electrode plate and the positive electrode plate. It is possible to remove a side reaction gas and reinject an electrolyte without separating a battery cell.
