Abstract
An electrical connection assembly and a battery pack signal acquisition device. The battery pack signal acquisition device has: a signal transmission bus; and an electrical connection assembly for electrically connecting a battery cell to the signal transmission bus to collect an electrical parameter of the battery cell. The electrical connection assembly and the signal transmission bus are respectively formed and electrically connected with each other. In the present invention, the electrical connection assembly can be replaced separately without replacing the signal transmission bus, which improves the convenience of use and reduces the later maintenance cost.
