Abstract

A battery module that can improve efficiency of operation in maintenance is provided. A battery module includes a battery and a power distribution unit configured to distribute power to a load, wherein the power distribution unit includes a base and a device mounting portion supported by the base and electrically connected to the base to distribute power from the battery to the load, and the base includes a battery connection portion for connection with the battery, and a load connection portion for connection with the load.

First claim

What is claimed is:

1. A battery module comprising:
a battery; and
a power distribution unit connected to the battery and configured to distribute power to a load, wherein
the power distribution unit includes a base and a device mounting portion supported by the base and electrically connected to the base to distribute power from the battery to the load, and
the base includes a battery connection portion for connection with the battery, and a load connection portion for connection with the load.

2. The battery module according to claim 1 , wherein
the base includes an installation portion on which the device mounting portion is installed,
the device mounting portion is provided with a connector connection portion to which a conductive member extending from the base is connected, and
the connector connection portion is provided at a front side of the device mounting portion that is located away from the installation portion.

3. The battery module according to claim 2 , wherein
the base includes an installation portion on which the device mounting portion is installed, and
the battery connection portion and the load connection portion are provided at a back side distant from the device mounting portion across the installation portion.

4. The battery module according to claim 2 , further comprising a case housing the battery and the power distribution unit, wherein
the case includes an opening configured to allow the device mounting to be exposed, and a cover covering the opening.

5. The battery module according to claim 4 , wherein
the case is fixed to a downward side of a vehicle floor,
the base is provided with the battery connection portion and the load connection portion at a position facing to the vehicle floor, and
the opening is provided at a front side distant from the vehicle floor across the base and the device mounting portion.

6. The battery module according to claim 1 , further comprising a pair of connection portions configured to connect via connector connection the base with the device mounting portion, wherein
the base includes an installation portion on which the device mounting portion is installed,
the installation portion includes one of the pair of the connection portions, and
another one of the pair of the connection portions is provided to the device mounting portion and positioned so as to be fitted to the one of the pair of connection portions when the device mounting portion is installed to the installation portion.

7. The battery module according to claim 6 , wherein
the base includes an installation portion on which the device mounting portion is installed, and
the battery connection portion and the load connection portion are provided at a back side distant from the device mounting portion across the installation portion.

8. The battery module according to claim 6 , further comprising a case housing the battery and the power distribution unit, wherein
the case includes an opening configured to allow the device mounting to be exposed, and a cover covering the opening.

9. The battery module according to claim 8 , wherein
the case is fixed to a downward side of a vehicle floor,
the base is provided with the battery connection portion and the load connection portion at a position facing to the vehicle floor, and
the opening is provided at a front side distant from the vehicle floor across the base and the device mounting portion.

10. The battery module according to claim 1 , wherein
the base includes an installation portion on which the device mounting portion is installed, and
the battery connection portion and the load connection portion are provided at a back side distant from the device mounting portion across the installation portion.

11. The battery module according to claim 10 , further comprising a case housing the battery and the power distribution unit, wherein
the case includes an opening configured to allow the device mounting to be exposed, and a cover covering the opening.

12. The battery module according to claim 11 , wherein
the case is fixed to a downward side of a vehicle floor,
the base is provided with the battery connection portion and the load connection portion at a position facing to the vehicle floor, and
the opening is provided at a front side distant from the vehicle floor across the base and the device mounting portion.

13. The battery module according to claim 1 , further comprising a case housing the battery and the power distribution unit, wherein
the case includes an opening configured to allow the device mounting to be exposed, and a cover covering the opening.

14. The battery module according to claim 13 , wherein
the case is fixed to a downward side of a vehicle floor,
the base is provided with the battery connection portion and the load connection portion at a position facing to the vehicle floor, and
the opening is provided at a front side distant from the vehicle floor across the base and the device mounting portion.
