A system in a vehicle includes a starter motor to start an engine of the vehicle. The system also includes a first battery connected to the starter motor to power the starter motor during the start of the engine and a second battery controllably connected in series or in parallel with the first battery to provide additional power to the starter motor during the start of the engine.

A control unit for a hybrid drive of a vehicle is provided. The hybrid drive includes an internal combustion engine and an electric machine. The hybrid drive is designed in such a way that the electric machine is used for providing a drive torque of the vehicle and for starting the internal combustion engine. The control unit is configured to predict a start time, at which at least a part of the total power of the electric machine is available for a starting process of the internal combustion engine. Furthermore, the control unit is configured to start the internal combustion engine at the predicted start time by way of the electric machine.

There is provided a solenoid device in which a fixed wall and a supporting wall having a protruding portion are provided in a flange portion of a bobbin, in which a surge absorption device is held in a space between the supporting wall and the fixed wall, and in which the protruding portion presses the surge absorption device; furthermore, a starter having the solenoid device is provided.

A booster is mounted on a vehicle having an idle stop function. The booster boosts an input voltage supplied from a battery, and outputs the boosted input voltage to an in-vehicle device. The booster includes a booster circuit and an output voltage sensor. The booster circuit is a chopper-type, and includes a reactor having one end connected to the battery and a switching element connected between an other end of the reactor and a ground. The output voltage sensor detects an output voltage of the booster circuit.

A vehicle power supply system and a method for operating the same are provided. The vehicle power supply system includes a main battery and a sub-battery to supply power to an electronic load inside a vehicle, and a controller to control supplying of the power to the electronic load using at least one of the main battery or the sub-battery, by monitoring the main battery and the sub-battery. The controller determines whether the main battery allows entrance into Idle Stop and Go, determines whether the sub-battery is able to assist the ISG, and controls the sub-battery to assist the main battery to supply the power to the electronic load, when the main battery allows the entrance into the ISG, when the sub-battery is able to assist the ISG, and when entering into the ISG.

A starter assembly includes a housing defining an interior, a rotatable pinion gear wherein the rotatable pinion gear extends exteriorly of the housing and operably coupling to a combustion engine, a torque sensor providing a torque output indicative of a torque experienced by the pinion gear, and a controller module configured operate a starting sequence for the starter assembly.

An electromagnetic switch for a starting device of an internal combustion engine may include a coil carrier, a coil winding, and a piston. The coil carrier may have a carrier wall which encloses a cavity. The coil winding may have a coil wire wound on a side of the carrier wall facing away from the cavity which provides a magnetic field within the cavity. The piston may be axially adjustable in the cavity. The piston may be disposed in a passive position and may be adjusted axially in a direction of a core. In the passive position, the piston and the core may define an axial gap therebetween in the cavity. The coil wire may have a first winding section and a second winding section wound in opposing directions. At least one winding of the second winding section may axially overlap the axial gap.

A current detector includes: a printed circuit board; and a resistor for detecting an electric current of the electrochemical device, wherein a connector having a first terminal is mounted on the printed circuit board, and the resistor has a second terminal which is brought into contact with the first terminal.

An override module allowing a vehicle operator to default the status of an automated start-stop system to “off.” A first embodiment uses a module that is installed in-line with a manual override button. A second embodiment uses a module that is installed on the vehicle's CAN bus.

This present disclosure discloses an ignition overcurrent protection device, which includes a switch, a current detection circuit, and a controller. The switch is electrically coupled between a starting power and a power-on connector; the power-on connector is configured for connecting to the automotive power. The current detection circuit is configured for detecting a current value flowing between the starting power and the power-on connector. The controller is coupled to the switch and the current detection circuit. The controller is configured to determine a current range where the current value is located, and determine a preset time threshold corresponding to the current range, and control the switch to be turned off when a duration of the current value reaches the preset time threshold. The present disclosure also provides a starting power equipment and ignition overcurrent protection.
