An electric starting system for an internal combustion engine is provided. The starting system includes a rechargeable battery, a battery receiver, and a starter motor. The rechargeable battery including a battery housing, internal circuitry housed within the battery housing, two voltage output terminals, and an enable terminal. The battery receiver includes a battery receptacle configured to receive the rechargeable battery, two voltage output terminals, and the enable terminal. The starter motor is configured to start the internal combustion engine. The internal circuitry is coupled to the enable terminal and configured to enable and disable an internal switch to provide power to one of the two voltage output terminals, the internal circuitry monitoring at least one internal condition of the rechargeable battery for a fault condition. The internal circuitry disables the internal switch upon detection of the fault condition.

A vehicle engine electric starter motor can bring a vehicle engine crankshaft up to a desired spinning speed prior to igniting the accompanying vehicle engine by way of multiple speed ratios. The vehicle engine electric starter motor includes a planetary gearset assembly. The planetary gearset assembly receives rotational drive input from an armature shaft, and transmits rotational drive output to an engine flywheel. Amid use of the vehicle engine electric starter motor, the vehicle engine electric starter motor can provide a first speed ratio by way of the planetary gearset assembly between the rotational drive input and the rotational drive output in a first mode of operation. And the vehicle engine electric starter motor can provide a second speed ratio by way of the planetary gearset assembly between the rotational drive input and the rotational drive output in a second mode of operation.

A gearbox arrangement of an electric machine of an engine includes a planetary gear arrangement configured to receive rotational input from the electric machine and from the engine and to mechanically couple the electric machine and the engine in first and second power flow directions, the planetary gear set comprising a ring gear, a ring brake, a free-wheel clutch attachable to a fixed structure and the ring brake, the free-wheel clutch permitting rotation of the ring brake in a first direction and preventing rotation of the ring brake in an opposite second direction, and an arrangement for moving the ring gear between a first position in which the ring gear is non-rotatably engaged with the ring brake and a second position in which the ring gear is non-rotatably engaged with the carrier. An engine starter and power generator device Is also provided.

A boost system for providing boost pressure to an air intake manifold of an engine includes a supercharger having rotors and a supercharger input shaft, an electric motor/generator, and a planetary gear set. The planetary gear set operates to transfer torque between the supercharger input shaft, the electric motor/generator and a crankshaft of the engine. The boost system can have a compact configuration.
