Patent ID: 7827007

Claim:
A battery characteristic simulating apparatus for supplying electric power which simulates a battery characteristic of a battery to a battery-driven type electronic appliance, the apparatus comprising: a voltage/current generating unit for outputting a predetermined generated value to both the battery and the electronic appliance; a voltage/current measuring unit for measuring a value of either the battery or the electronic appliance when the voltage/current generating unit outputs the predetermined generated value; a characteristic data acquiring unit for acquiring a battery characteristic of the battery based upon characteristic data made by combining the predetermined generated value outputted from the voltage/current generating unit to the battery with a measured value of the battery measured by the voltage/current measuring unit; a storage unit for storing the battery characteristic of the characteristic data acquiring unit; a simulation signal producing unit for calculating a generated value for the electronic appliance based upon the battery characteristic stored in the storage unit and the measured value of the electronic appliance measured by the voltage/current measuring unit, and for outputting the calculated generated value to the voltage/current generating unit; and a housing, wherein the voltage/current generating unit, the voltage/current measuring unit, the characteristic data acquiring unit, the storage unit, and the simulation signal producing unit are provided within the same housing.
