A control apparatus for an electric vehicle includes a first motor (traveling motor) for traveling, a battery (high-voltage battery), a second motor (generator motor) for electricity generation, an engine (rotary engine), a first controller (engine ECU), a second controller (motor ECU), and a sensor (voltage-current sensor). The second controller is configured to start the engine by causing the second motor to perform power running, cause the second motor to perform electricity generation driving such that the battery is charged, and adjust a stop position of the engine by causing the second motor to perform power running subsequently to a stop of the engine by the first controller in a case where a state of charge of the battery becomes high and the second motor finishes the electricity generation driving.

A control device includes an ECU configured to acquire, from each of a plurality of vehicles having a secondary battery and being configured to supply power to the outside, information indicating a charging rate of the secondary battery and vehicle model information, generate arrangement position information by which a arrangement position is allocated to each of the plurality of vehicles in a case where the plurality of vehicles supply the power to the outside in parallel to each other, based on the charging rate of the secondary battery and the vehicle model information, and output the arrangement position information.

A removably attachable vehicle battery charger includes a housing having an engine (e.g., a high efficiency diesel engine) therein to charge a battery of an electric vehicle. The housing includes a tongue that may be received by a receiver hitch on the electric vehicle. The tongue may have charging components (e.g., wires and electrical contacts) that interact with electrical components (e.g., electrical contacts and wires) in the receiving hitch to provide charge to the batteries of the vehicle. The engine runs to charge the batteries of the electric vehicle, as needed or as programmed by a user.

The present invention relates to an electric power generating system for vehicles. The system includes at least one wind turbine positioned to capture incoming air which is coupled to a wind generator for converting into electric power. The system has solar panels installed on the exterior surface of the vehicle such as trailer of a semi-truck for absorbing solar energy and converting into electric power. The electric power produced by the wind generator and the solar panels is stored in a battery pack for providing electric power to the electric battery of the vehicle. An emergency generator provides electric power to the vehicle when the power of both the electric battery and the battery pack is insufficient. The system slows down the depletion of battery charge, thus enabling the vehicle to stay on the road for a longer duration and improves overall charging experiences for the electric vehicle.
