Claims18
A storage battery device, comprising:
- a cell unit including a plurality of battery cells;
- an electric flow path material configured to form a current path through which electric power is supplied from or to the battery cells;
- and
- a radiator thermally coupled to the electric flow path material, wherein
- the electric flow path material includes a bus bar that connects the battery cells to each other, and
- the radiator is thermally coupled to the bus bar connecting the battery cells to each other, and further comprising:
- a battery management unit placed between the cell unit and the radiator, and that includes a through hole for the bus bar to thermally couple to the radiator, the battery management unit configured to manage the cell unit, wherein
- the radiator is thermally coupled to the battery management unit.

- a cell unit including a plurality of battery cells;
- an electric flow path material configured to form a current path through which electric power is supplied from or to the battery cells;
- a radiator thermally coupled to the electric flow path material;
- a DC-DC converter electrically connected to the cell unit via the electric flow path material, the DC-DC converter configured to boost a voltage of electric power of the cell unit for output, and step down a voltage of external electric power for output to the cell unit, wherein the radiator is thermally coupled to the DC-DC converter;
- and
- a battery management unit electrically connected to a bus bar that connects the battery cells to each other, the battery management unit configured to manage the cell unit, wherein
- the radiator includes a hollow part that allows a coolant to flow through an inside thereof, and
- the DC-DC converter and the battery management unit are disposed at opposing sides of the radiator via the hollow part and are thermally coupled to the radiator.
