Power supply unit and electric apparatus
First Claim
1. A power supply unit for supply of power to an electric apparatus, comprisingan indicator unit,a power source containing a nonaqueous electrolyte secondary battery,an introduction-detecting unit for detecting introduction of the electric apparatus into vehicle for transportation of the electric apparatus,a voltage-detecting unit for detecting the voltage of the power source,a memory unit for storing a first voltage and a second voltage lower than the first voltage,a judgment unit for determining whether the voltage of the power source detected by the voltage-detecting unit is not lower than the first voltage, if the introduction of the electric apparatus into vehicle is detected previously by the introduction-detecting unit, anda forced discharge unit for causing the indicator unit to notify that the electric apparatus is in the state prohibiting introduction thereof into vehicle and forcibly discharging the power source until the voltage of the power source detected by the voltage-detecting unit reaches the second voltage by supplying power from the power source to the indicator unit, if the voltage of the power source is judged not lower than the first voltage by the judgment unit.

Abstract
Provided is a power supply unit that notifies the third person that the electric apparatus is in the state prohibiting introduction into vehicle and also make the electric apparatus in the state safely introducible into vehicle at the same time.
The power supply unit comprises an introduction-detecting button for detecting introduction of an electric apparatus into vehicle previously, a voltage-detecting unit for detecting the voltage of the power source, a memory unit for storing a control-initiating voltage and a control-terminating voltage lower than the control-initiating voltage, and a control unit for determining, when introduction into vehicle is detected previously with an introduction-detecting button, whether the voltage of the power source detected by the voltage-detecting unit is not lower than the control-initiating voltage, supplying power from the power source to the LED if the voltage of the power source is judged not lower than the control-initiating voltage, causing the LED to notify that the electric apparatus is in the state prohibiting introduction into vehicle, and forcibly discharging the power source until the voltage of the power source reaches the control-terminating voltage.
