The present invention provides a battery pack temperature acquisition module and system. The battery pack temperature acquisition module has: an insulation body; a temperature sensing element mounted on the insulation body and configured to detect a temperature of a battery cell; and a connection terminal mounted on the insulation body. The temperature sensing element has a lead for transmitting a temperature signal, one end of the connection terminal is electrically connected with the lead of the temperature sensing element, and the other end is adapted to be connected to a signal acquisition line to electrically connect the temperature sensing element to the signal acquisition line, the connection terminal and the insulation body are respectively formed. In the present invention, the battery pack temperature acquisition module can be replaced separately without replacing the signal acquisition line, which improves the convenience of use and reduces the later maintenance cost.
