Abrégé
A supercharging system includes: a first supercharger including a first compressor for compressing air to be supplied to an engine; a second supercharger including a second compressor for further compressing air compressed by the first compressor; and a controller for controlling the first supercharger and the second supercharger. At least one of the first supercharger or the second supercharger further includes an electric motor for driving the first compressor or the second compressor. At least one of the first supercharger or the second supercharger further includes a turbine configured to be rotary driven by exhaust gas from the engine, and a nozzle vane configured to adjust a flow-path area of the exhaust gas flowing into the turbine. The controller includes: an electric motor control part configured to, if an amount of charge of a battery for supplying electric power to the electric motor is less than a first threshold, set an upper limit value of an output command value for the electric motor to be lower than when the amount of charge of the battery is not less than the first threshold, or switch operation of the electric motor to regenerative operation; and a vane control part configured to, if the amount of charge of the battery is less than the first threshold, control an opening degree of the nozzle vane so that the flow-path area decreases with a control of the electric motor by the electric motor control part.
