  • Power supply system and state of charge estimating method
    Patent number: 6366055
    Abstract: A power system where energy generated at a deceleration time of a running vehicle such as an automobile can be accepted as regenerative energy sufficiently and safely is provided. In a power system 10, a non-aqueous solution system secondary battery group 1 where 10 to 11 lithium ion secondary battery cells are connected in series and an aqueous solution system secondary battery group 2 where 18 control valve type lead-acid battery cells are connected in series are connected in parallel. The battery capacity of the non-aqueous solution system secondary battery group 1 is smaller than that of the aqueous solution system secondary battery group 2.
