1. A battery pack comprising:
battery cells;
bus bars configured to provide electrical connection among the battery cells;
a holder that holds the bus bars;
a cover which defines a passage along with the holder through which a heat transfer medium passes;
a fluid device that is configured to create a flow of the heat transfer medium in said passage to transfer heat generated by the bus bars or the battery cells to the heat transfer medium and
a control device that is configured to obtain data on at least one of the bus bars and the battery cells and control the fluid device based on the obtained data, wherein
the bus bars are exposed to the passage,
the fluid device is provided in the cover, and
the control device includes a circuit and is disposed in and attached to the cover to have the circuit exposed to the flow of the heat transfer medium to transfer heat generated by the circuit to the heat transfer medium.
