A vehicle includes an engine, a start-stop system configured to stop and restart operation of the engine in response to predetermined triggers, and an auxiliary air conditioning AC system including a controller communicably coupled to the start-stop system. The start-stop system is configured to provide a first indication to the auxiliary AC system indicating ignition of the engine and a second indication to the auxiliary AC system after stopping the engine. The auxiliary AC system is configured to turn off the auxiliary AC system in response to receiving the first indication and restart the auxiliary AC system in response to receiving the second indication.

A vehicle control apparatus to be mounted on a vehicle including an engine includes an electric motor, an electricity storage device, and a motor controller. The electric motor is coupled to the engine and generates motor power. The electricity storage device is coupled to the electric motor through a power supply cable. The motor controller causes execution of an assistance mode. The assistance mode includes controlling the electric motor to a powering state to transmit the motor power to the engine in operation. The motor controller permits the execution of the assistance mode on the condition that a rotation speed of the electric motor is lower than a threshold. The motor controller prohibits the execution of the assistance mode on the condition that the rotation speed of the electric motor is higher than the threshold.

A control device comprises an acquisition unit that acquires a current to or from the battery and a voltage of a battery, a calculation unit that calculates an internal resistance of the battery based on the current and the voltage when the regenerative power generation is performed by a rotary electric machine, and a permission determination unit that determines whether to permit an automatic stop of an engine depending on whether restarting of the engine is enabled based on power running drive of the rotary electric machine. The calculation unit calculates a value of the internal resistance each time the regenerative power generation or the power running drive is performed before the engine enters an automatic stop state. The permission determination unit determines whether to permit the automatic stop based on a latest value of the internal resistance among values of the internal resistance calculated by the calculation unit.

A system for discharging or charging a capacitor of a hybrid vehicle according to the present disclosure includes a target state of charge (SOC) module and a capacitor charge/discharge module. The target SOC module determines a target state of charge of the capacitor based on a speed of the vehicle. The capacitor charge/discharge module determines whether a state of charge of a capacitor is greater than a target state of charge. The capacitor charge/discharge module dissipates power from the capacitor to at least one of a battery of the vehicle and an electrical load of the vehicle when the state of charge of the capacitor is greater than the target state of charge.

A battery starting and charging system that monitors battery and other sensor readings; tracks vehicle state, determines a charging voltage based on battery temperature and vehicle state; sets the alternator to charge the battery with the charging voltage; determines current collected parameters based on the battery and other sensor readings; and makes vehicle start predictions based on the current collected parameters. The system can also determine whether the vehicle actually started; add the current collected parameters to a set of start events if it started, and to a set of no-start events if it didn't start. The start prediction can also be based on the sets of start and no-start events for one or multiple vehicles. The collected parameters and start predictions can also be based on collected weather data. The system can use a local interconnect network (LIN) alternator with a LIN network.

A vehicle power supply apparatus includes first and second power supply systems, first and second switches, first and second switch controllers, a generator motor controller, an engine controller, and an idling stop determination unit. The idling stop determination unit determines whether or not to inhibit an idling stop control on the basis of a current of an first electrical energy accumulator of the first power supply system, a current of a second electrical energy accumulator of the second power supply system, or a voltage of a generator motor of the second power supply system, or any combination thereof, while recognizing a third control signal to be transmitted to the generator motor, a first control signal to be transmitted to the first switch, and a second control signal to be transmitted to the second switch.

An automotive battery draw monitor for monitoring the parasitic draw on an automotive battery. The invention uses a shunt and a multi-meter to measure the voltage drop between the negative battery terminal and the negative battery cable. The invention is contained within a housing and powered via a power cable that connects the multi-meter to the positive terminal of the battery. The invention is grounded using a ground wire connected to the shunt.

An engine including an engine block having a cylinder defining a front of the engine, a blower housing coupled to the engine block and defining a hot half positioned adjacent the front of the engine and a cool half opposite the hot half, and an electric starter system positioned within the blower housing. The electric starting system includes a starter mount assembly coupled to the blower housing, an electric starter motor retained by the starter mount assembly and positioned in the cool half, and a battery mounted to the blower housing and positioned in the cool half. The battery is electrically coupled to the electric starter motor.

A vehicle includes an engine, an alternator, and a battery bank electrically connected to the alternator via a connection line. The connection line includes a current sensor configured to measure an electrical current through the connection line. The vehicle also includes a start-stop system configured to determine, during a time when the engine is off, that a voltage of the battery bank is below a first threshold value for a first predetermined period, provide a control signal to a starter to start the engine to initiate charging of battery bank, determine, by the current sensor, that the electrical current is below a second threshold value, and in response to the determination, provide a control signal to turn the engine off to terminate the charging of the battery bank.
