BATTERY PACK
First Claim
1. A battery pack that can be connected to a battery-driven device and supply the battery-driven device with electric power for driving the battery-driven device, and can be placed on a charging base and supplied with electric power from an energizing coil included in the charging base for charging the battery pack in a non-contact charging manner, the battery pack comprising:
- a rechargeable battery cell;
an energized coil that can be electromagnetically connected to the energizing coil included in the charging base;
a temperature-detecting portion that detects the temperature of said rechargeable battery cell;
a terminal-switching portion that is connected to said temperature-detecting portion in series;
a pack-controlling portion that controls ON/OFF of said terminal-switching portion; and
connection terminals that allow the battery pack to be electrically connected to the battery-driven device,wherein said connection terminals includesa pair of power supply terminals through which said rechargeable battery cell can be charged/discharged, anda temperature terminal that is connected to said temperature-detecting portion,wherein said pack-controlling portion is connected to said temperature terminal, andwherein when the battery pack is charged by the charging base in the non-contact charging manner, said terminal-switching portion is turned OFF so that the battery pack can communicate with the battery-driven device through said temperature terminal.

Abstract
The battery pack includes a rechargeable battery cell, an energized coil, a temperature detector, a switch, a controller, power supply terminals, and a temperature terminal. The coil can be electromagnetically connected to an energizing coil of a charger. The detector detects the cell temperature. The switch is serially connected to the detector. The controller controls ON/OFF of the switch. The pack can be electrically connected through the terminals to a battery-driven device. The cell can be charged/discharged through the power supply terminals. The temperature terminal is connected to the detector. The controller is connected to the temperature terminal. When the pack is charged by the charger in the non-contact charging manner, the switch is turned OFF so that the pack can communicate with the device through the temperature terminal.
