On-board emergency reporting apparatus and auxiliary battery device for the same

An auxiliary battery device attachable to and detachable from an emergency reporting apparatus configured to perform an emergency reporting procedure by using an electric power supplied from the auxiliary battery device, the auxiliary battery device comprising:

• a battery cell;
• a control circuit configured to start a supply of the electric power from the battery cell to the emergency reporting apparatus in response to a trigger event that is occurred in the emergency reporting apparatus and causes the emergency reporting procedure to be started;
• and
• a timer circuit configured to measure time elapsed since the supply of the electric power from the battery cell to the emergency reporting apparatus is started,
• wherein the control circuit stops the supply of the electric power from the battery cell to the emergency reporting apparatus, when the elapsed time exceeds a predetermined threshold time period.

An auxiliary battery device attachable to and detachable from an emergency reporting apparatus configured to perform an emergency reporting procedure by using an electric power supplied from the auxiliary battery device, the auxiliary battery device comprising:

• a battery cell;
• a control circuit configured to start a supply of the electric power from the battery cell to the emergency reporting apparatus in response to a trigger event that is occurred in the emergency reporting apparatus and causes the emergency reporting procedure to be started;
• and
• a detection circuit configured to detect a predetermined operation performed by a user,
• wherein the control circuit stops the supply of the electric power from the battery cell to the emergency reporting apparatus, when the predetermined operation is detected within a predetermined period of time after the supply of the electric power is started.

In an emergency reporting apparatus for use in combination with an auxiliary battery device attachable to and detachable from the emergency reporting apparatus, a method of controlling a power supply mode for supplying power to the emergency reporting apparatus, the method comprising:

• switching the power supply mode from a vehicle battery mode, where the power is supplied from a vehicle battery, to an auxiliary battery mode, where the power is supplied from the auxiliary battery device, in response to a trigger event to start an emergency reporting procedure;
• measuring time elapsed since the power supply mode switches from the vehicle battery mode to the auxiliary battery mode;
• and
• switching back the power supply mode from the auxiliary battery mode to the vehicle battery mode, when the measured elapsed time exceeds a predetermined threshold time period.
