Temperature sensor mounting structure and battery module structure

1. A temperature sensor mounting structure for a battery module including at least two batteries, each of which is formed by connecting single cells together in series, the temperature sensor mounting structure comprising:

a temperature-measuring device that measures the temperature of at least one of the batteries;

a covering device that covers the temperature-measuring device; and

a spacer disposed between two of said batteries,

wherein said covering device includes a spanning portion and a plurality of upright walls,

wherein said spacer includes a plurality of upright walls,

wherein movement of the covering device in an axial direction of the batteries is restricted by said spacer and said plurality of upright walls of said covering device, and

wherein movement of the covering device in a rotation direction around an axis of one of the batteries is restricted by said spanning portion of said covering device and said plurality of upright walls of said spacer.

2. The temperature sensor mounting structure according to claim 1 , wherein the covering device is mounted on the at least one of the plurality of batteries using a clip connector or a band connector.

3. The temperature sensor mounting structure according to claim 1 , wherein a sensor protection device is provided on an interior side of the covering device.

4. The temperature sensor mounting structure according to claim 1 , wherein the covering device has an opening to allow air to pass between the interior and exterior thereof.

5. A temperature sensor mounting structure for a battery module that is formed by connecting single cells together in series, the temperature sensor mounting structure comprising:

a temperature-measuring device that measures the temperature of the battery module; and

a covering device that covers the temperature-measuring device;

wherein said battery module includes protruding portions formed on an outer circumference of said battery module, and

wherein movement of said covering device is restricted by said protruding portions of said battery module.

6. The temperature sensor mounting structure according to claim 5 , wherein movement of said covering device in an axial direction of said battery module is constricted by said protruding portions of the battery module.
