摘要： This application discloses a battery cell, a battery module, a battery pack, an energy storage system, and an electric vehicle. An electrochemical cell includes a positive electrode plate, a negative electrode plate, and at least three separators located between the positive electrode plate and the negative electrode plate. A first separator located at the middle among the at least three separators is a conductive layer. A second separator located between the positive electrode plate and the first separator and a third separator located between the negative electrode plate and the first separator are insulation layers. The first separator is connected to a communication chip. When the positive electrode plate pierces the second separator and reaches the first separator, or the negative electrode plate pierces the third separator and reaches the first separator, an internal short circuit of the electrochemical cell may be caused. The communication chip may receive, in time, an electrical signal sent by the first separator, and report fault information to a battery management unit, so that safety in use of a battery is improved.
