A multifunctional battery cover (100) and a power battery pack (17) thereof. The multifunctional battery cover (100) comprises a cover body (1), a plurality of leading-out terminals (3) disposed on the cover body (1), and at least one electric signal collecting unit. An input end of each electric signal collecting unit is connected with a single battery cell (11) in the battery pack. An output end of each electric signal collecting unit is connected with one of the leading-out terminals (3). The leading-out terminals (3) are all connected with a battery management system, and are used for transmitting collected voltage information of the battery pack (17) to the battery management system. The multifunctional battery cover (100) has advantages of simple and reliable assembly and strong anti-interference capability. In addition, the leading-out terminals (3) of the multifunctional battery cover (100) send the collected electric signals of each battery cell (11) in the battery pack (17) to the external battery management system, thus achieving dual effects of voltage detection and current equalization during charging; therefore, the performance of the battery cell can be effectively controlled and detected, and the service life of the battery is prolonged.
