Abstract

A battery characteristic simulating apparatus is improved which is capable of supplying electric power for simulating a battery characteristic of a battery to a battery-driven type electronic appliance. The battery characteristic simulating apparatus is featured by that a voltage/current generating unit; a voltage/current measuring unit; a characteristic data acquiring unit; a storage unit; and a simulation signal producing unit are provided within the same housing of the battery characteristic simulating apparatus.

Claims

1. 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 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.

2. The battery characteristic simulating apparatus as in claim 1, wherein

the battery is a rechargeable battery.

3. The battery characteristic simulating apparatus as in claim 1, wherein

the battery characteristic is a voltage/current characteristic which is outputted by the battery.

4. The battery characteristic simulating apparatus as in claim 1, wherein

the storage unit stores thereinto the battery characteristic with respect to each of temperatures.

5. The battery characteristic simulating apparatus as in claim 1, 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 connected to each other via exclusively-used buses.
