Vehicle power source

A vehicle power source mounted on a vehicle, the vehicle power source comprising:

• a generator coupled to an engine;
• a power storage coupled to the generator;
• a vehicle body equipment group coupled, in parallel with the power storage, to the generator;
• a current consumption estimating unit that estimates current consumption of the vehicle body equipment group, on a basis of a generated current of the generator and a charge and discharge current of the power storage;
• a charge and discharge current setting unit that sets a target charge and discharge current of the power storage, on a basis of a state of charge of the power storage;
• a generated current setting unit that sets a target generated current of the generator, on a basis of the current consumption of the vehicle body equipment group and the target charge and discharge current of the power storage;
• and
• a generated current controller that controls the generated current of the generator, on a basis of the target generated current of the generator.
