Abstract: The present disclosure relates to a battery cover assembly, a battery cell, a battery module, a power battery pack and an electric vehicle. The battery cover assembly includes a cover plate 104, an electrode inner terminal and an electrode outer terminal. The electrode inner terminal is electrically connected to the electrode outer terminal through a current interrupt structure disposed on the cover plate 104. The current interrupt structure includes a sealed chamber 103 configured to fill a gas-producing medium therein. The sealed chamber 103 is configured to make the gas-producing medium to be electrically connected to positive electrodes and negative electrodes of a battery. When a voltage difference between the positive electrodes and negative electrodes of the battery exceeds a rated value, the gas-producing medium is capable of producing gas, to disrupt the electrical connection between the electrode inner terminal and the electrode outer terminal under the action of the pressure of the gas. That is, gas production in the sealed chamber in the cover assembly is independent of gas production inside the battery, so that gas pressure can be formed for the current interrupt structure in time to activate the current interrupt structure in time, thereby improving the battery safety.
