The purpose of the present invention is to swiftly start up an engine in a range in which electrical equipment having electric power supplied thereto by a battery is not reset, even in cases when the battery is insufficiently charged and the battery is deteriorated. An engine start-up device according to the present invention starts up an engine by transmitting, to the engine, the rotary force of a direct-current motor driven by a battery. The engine start-up device is provided with: a battery-voltage acquisition unit for acquiring the battery voltage of the battery; a target-current-value calculation unit which calculates, on the basis of the battery voltage acquired by the battery-voltage acquisition unit, a target current value for a motor current to be supplied from the battery to the direct-current motor; and a motor-current control unit for controlling a switching element which is connected to the direct-current motor, and through which the motor current flows, such that the motor-current value of the motor current approaches the target current value.

A starter assembly including a starter and starting device. The starter includes: an electric motor including a motor shaft; an output shaft non-rotatably connected to the motor shaft; and a one-way clutch including a first race including an axially fixed pinion gear and a second race non-rotatably connected to the output shaft. The starting device includes a wrap spring clutch with first and second ends. For a start mode: the electric motor rotates the motor shaft and the pinion gear in a first circumferential direction; the pinion gear rotates the second end, with respect to the first end, in the first circumferential direction; and, the wrap spring clutch rotates a torque converter shell in the first circumferential direction. For a first phase of a release mode: the electric motor rotates the second race in a second circumferential direction; and the first race rotates in the second circumferential direction.

Outdoor power equipment includes an internal combustion engine including an electric motor, a battery receiving port, a rechargeable battery removably attached to the battery receiving port, wherein the rechargeable battery is configured to power the electric motor to start the engine, an implement driven by the internal combustion engine, a release mechanism movable to an engaged position to put the implement in a ready-to-run condition in which the implement is ready to be driven by the engine, a run sensor configured to detect the ready-to-run condition, a switch actuated by the release mechanism, and a control module coupled to the switch so that the switch provides a signal to the control module when the release mechanism is in the engaged position and the control module turns on the electric motor to start the engine in response to the signal from the switch and the run sensor detecting the ready-to-run condition.

An engine start control device is provided with: a starter relay that is provided between a battery and a starter motor; a start abnormality determining means that determines the occurrence of start abnormality of an engine; and a start control means, which turns on the starter relay, and starts supplying power from the battery to the starter motor in the cases where a start instruction signal is inputted from a start switch, and which turns off the starter relay in the cases where the start abnormality determining means determined the occurrence of start abnormality of the engine.

A rechargeable battery jump starting device with a vehicle or equipment battery detection system. The vehicle or equipment battery detection system is configured for detecting the connection of the rechargeable battery jump starting device with the vehicle or equipment battery to be jump charged.

Disclosed are a starting device and a starting system of a vehicle. The starting device includes a first connection line, a second connection line and a starting module. The first connecting line and the second connecting line are configured to transmit a current provided by a starting power source to provide a voltage of the starting power source to a vehicle; the starting module is connected to at least one of the first connection line and the second connection line; the starting module is turned on when the first connection line and the second connection line are not connected to a vehicle battery of the vehicle; and the starting module is turned off, when the vehicle battery of the vehicle is charged and the first connection line and the second connection line are abnormally connected to the vehicle battery of the vehicle.

Engine systems which are easier starting and more resistant to degradation and discharge of their batteries are desirable in a wide range of equipment markets. The present engine systems utilize a selection module which selective switches from a first state when the battery is adequately charged to a second state which enables the use of auxiliary components such as special starting stators and regulators which can power the engine control module even when the battery is too discharged to power the engine control module directly.

An aircraft starting and generating system includes a starter/generator and an inverter/converter/controller that is connected to the starter/generator and that generates AC power to drive the starter/generator in a start mode for starting a prime mover of the aircraft, and that converts AC power, obtained from the starter/generator after the prime mover have been started, to DC power in a generate mode of the starter/generator. A four leg inverter is coupled with the DC power output and has an inverter/converter/controller (ICC) with a four leg MOSFET-based bridge configuration that drives the starter/generator in a start mode for starting a prime mover of the aircraft, and converts DC power to AC power in a generate mode of the starter/generator. A four leg bridge gate driver is configured to drive the four leg MOSFET-based bridge using pulse width modulation (PWM) during start and generate mode.

An electric starting system for an internal combustion engine is provided. The starting system includes a battery, a starter motor, and a blower housing. The starter motor is configured to start the internal combustion engine. The battery is integrated with the blower housing.
