Control system and control method of combined system having secondary battery and generator
First Claim
1. A control system controlling a combined system having a secondary battery and an electric power generator, and serving as a power supply for a load, the secondary battery being charged by use of the electric power generator, the control system comprising:
- a charging efficiency calculating section calculating a charging efficiency of the secondary battery in conjunction with an electric power output of the electric power generator;
a total efficiency data calculating section calculating total efficiency data in response to a demanded electric power of the load; and
an electric power supply controlling section controlling allocation of an electric power output of the secondary battery and an electric power output of the electric power generator both to be supplied to the load;
wherein the electric power supply controlling section sets an electric power output of the secondary battery and an electric power output of the electric power generator both to be supplied to the load on the basis of the charging efficiency and the total efficiency data.

Abstract
A control system and a control method of a combined system having a secondary battery 15 and a fuel cell power generation system 12 are disclosed. wherein a vehicle controller 20 repeats a secondary battery-charging running mode wherein electric power output of the power generation system 12 is supplied to the secondary battery 15 and a motor 11, and a secondary battery-discharging running mode wherein electric power output of the power generation system 12 and electric power output discharged from the secondary battery 15 are supplied to the motor 11. In such a control, the amounts of electric power output of the power generation system 12 and electric power output discharged from the secondary battery 15 are set to values to provide the maximum total efficiency that is computed in conjunction with a charging efficiency of the secondary battery 15 during the secondary battery-charging running mode.
