OG exemplary drawing
 
1. A current control device for controlling current from a battery, comprising:
a constant current circuit to which a voltage from the battery is being applied, the constant current circuit drawing a constant current from a positive pole of the battery that depends on the voltage that is applied and returns the constant current to a negative pole of the battery, and
a processing unit for performing processing,
wherein the processing unit is configured to:
set a value of the constant current drawn by the constant current circuit,
adjust the voltage being applied to the constant current circuit to a voltage according to the set value that is set,
obtain current information indicating the constant current drawn by the constant current circuit, and
determine whether or not to adjust the voltage being applied to the constant current circuit based on a difference value between the constant current indicated by the obtained current information and the set value that is set.
