A generator is controlled by a controller to generate power sufficient to a battery quickly in addition to power which is required by a wheel-drive motor for a while after a car is started and until a battery charging ratio becomes higher than a first predetermined ratio, between 80% and 100% for example. When the battery charging ratio becomes higher than the first predetermined ratio, the generator is controlled to generate a regulated power which is obtained by adding a constant power to the mean value of the power required by the wheel-drive motor to prevent the battery from generating gases due to overcharging. When the battery-charging ratio further increases and becomes higher than a second predetermined ratio, 120% for example, the generator is controlled to generate less power than the requirement of the wheel-drive-motor.

[ What is claimed is:] [1.] A method for controlling a generator for a series-hybrid car including an engine-driven generator, an assembled battery, and a wheel-drive motor energized by said generator and said battery, said method comprising the steps of:detecting current wheel-drive-motor power;memorizing said current wheel-drive-motor power once in a set time;detecting battery charging state; andcontrolling said generator to generate output power in accordance with said battery charging state, whereinsaid step of controlling said generator comprises a first step of controlling said generator to generate maximum output power if said charging state of said battery is lower than a first level; andwhen said charging state becomes higher than said first level, a second step of controlling said generator to generate output power which is a sum of a fixed power and said current wheel-drive-motor power memorized during said step of memorizing.
