A battery type identifying device is capable of identifying the type of a vehicle-mounted lead storage battery. The battery type identifying device includes: a charge processing unit which, on the condition that the state of a lead storage battery has reached a prescribed state as a result of a reduction in the amount of electricity stored therein from a fully charged state, carries out a determination charging process of charging the lead storage battery for a prescribed time; an accepted amount acquiring unit which acquires an amount accepted by the lead storage battery in the period during which the determination charging process is being carried out; and a determining unit which determines whether the lead storage battery is a liquid-type lead storage battery on the basis of the accepted amount acquired by the accepted amount acquiring unit.

Battery type identifying device, and method for identifying battery type

A vehicle control device includes at least one ECU configured to: when charging the first battery from the power generation device is possible and a restriction on operation of the power generation device is predicted during traveling, control the power generation unit such that the first battery is charged from the power generation device and control the power generation unit such that the second battery is charged in a case where an SOC of the first battery is equal to or higher than a threshold; and when the charging is not possible, the SOC of the first battery is equal to or lower than a threshold and an SOC of the second battery is equal to or higher than a threshold and the restriction is predicted during traveling, control the power generation unit such that the first battery is charged from the second battery.

Vehicle control device

In performing double drive startup for starting up an engine while cranking the engine by both a first motor and a second motor, the cranking of the engine by one of the first motor and the second motor is finished earlier than the cranking of the engine by the other of the first motor and the second motor.

Engine apparatus

A control system of a vehicle includes: an engine; a plurality of accessories including an air conditioner; a battery; a generator; and an ECU configured to automatically stop the engine, control the generator to charge or discharge the battery, inhibit the engine from being automatically stopped, calculate a first stop time as a length of time for which the engine can be automatically stopped, during operation of the air conditioner, calculate a first electric quantity as an estimated quantity of electricity consumed, calculate a second stop time as a length of time for which the vehicle is predicted to be stopped in the future, calculate a second electric quantity as an estimated quantity of electricity consumed, and determine the SOC target value, based on the first electric quantity and the second electric quantity.

Vehicle control system

A power supply control apparatus is provided with: a first calculating device configured to calculate a vehicle stop time rate on the basis of a travel history of the vehicle; a second calculating device configured to calculate a stoppable time rate on the basis of the travel history, and an estimating device configured to estimate an electric power amount associated with the idling stop control, on the basis of the calculated stoppable time rate if the idling stop control is allowed when the vehicle decelerates, and to estimate the electric power amount, on the basis of the calculated vehicle stop time rate if the idling stop control is not allowed when the vehicle decelerates.
