The present invention provides a control apparatus configured to control a power unit, wherein the power unit comprises a battery, and a temperature adjuster configured to adjust a temperature of the battery to a target temperature at the time of charge or discharge of the battery, and the control apparatus calculates, based on information concerning a demand response plan used to adjust a power demand and supply, an incentive obtained by charge or discharge of the battery by the demand response plan and a power cost needed to adjust the temperature of the battery to the target temperature by the temperature adjuster at the time of charge or discharge of the battery, and controls, in a case where the incentive is larger than the power cost, the power unit to execute charge or discharge of the battery by the demand response plan.

Control apparatus, management server, control method, and storage medium

A control system is a control system that controls transfer of electric power between a power grid and a secondary battery that is mounted in a vehicle and stores electric power for travel and includes a determiner configured to determine whether a state in which charging electric power or discharging electric power is equal to or less than a threshold continues for a predetermined time on the basis of a detection result of the charging electric power with which the secondary battery is charged or the discharging electric power discharged from the secondary battery, and a controller configured to cause the transfer of electric power between the power grid and the secondary battery to stop when the determiner determines that the state in which the charging electric power or the discharging electric power is equal to or less than the threshold continues for the predetermined time.

Control system, control method, and storage medium

A charge/discharge management apparatus for executing charge/discharge of a battery of a vehicle electrically connected to a facility, comprising an obtaining unit for obtaining use histories of a plurality of batteries corresponding to a plurality of vehicles electrically connected to the facility, and a selection unit for selecting a battery subjected to execution of charge/discharge from the plurality of batteries based on priority decided from the use histories.

Charge/discharge management apparatus and vehicle

A vehicle power-supply unit includes a high-voltage battery, a low-voltage battery having a lower voltage than the high-voltage battery, and an inlet, and is capable of connecting a feed connector of an external power source to the inlet and supplying electric power from the external power source to a charge target which is at least one of the high-voltage battery and the low-voltage battery. The power-supply unit includes: charge control means that controls charging of the charge target; and a battery voltage sensor that detects a voltage of the low-voltage battery. If a low-voltage battery voltage value VL becomes not higher than a charge abort threshold Vabort while connecting the feed connector to the inlet and supplying electric power from the external power source to the charge target, the charge control means stops supply of electric power from the external power source to the charge target.

Vehicle power-supply unit

A relay control system for an electric vehicle includes an electric power line, a relay, an operation member, a state sensor, a rotational speed detector, a shift position detector, and a relay disconnection permitting device. The state sensor is configured to sense that a signal circuit through which a signal related to a state of the operation member flows is changed into a disconnecting operation state. The rotational speed detector is configured to detect a rotational speed of the electric motor. The shift position detector is configured to detect a shift position of the electric vehicle. The relay disconnection permitting device permits disconnection of the relay based on the rotational speed detected by the rotational speed detector and the shift position detected by the shift position detector if the state sensor senses that the signal circuit is changed into the disconnecting operation state.

Relay control system for electric vehicle and method for controlling relay of electric vehicle

A controller is provided for a permanent magnet field motor including two rotors concentrically provided around a rotating shaft and a phase changing device for changing an angle of relative displacement in a circumferential direction between two rotors to serve as a power source for driving driven wheels of an all-wheel drive vehicle having two main driving wheels and at least two driven wheels, the controller including a drive control portion to control driving of the motor according to a drive mode of the all-wheel drive vehicle; and a phase instruction portion to issue an instruction, when the drive mode of the all-wheel drive vehicle is a main-driving-wheel drive mode, to set the angle of relative displacement at an angle at which a magnetic flux generated at each of the two rotors is weakened, as compared with that generated at each of the two rotors in an all-wheel drive mode.

Controller for motor

A hybrid vehicle implements a required traveling condition by generating a required driving force necessary to drive the vehicle even in the case where a supply source of a working fluid develops a malfunction. The hybrid vehicle is equipped with a motor which changes the phase difference between two rotors and an engaging/disengaging device which turns on/off the supply of a driving force of an internal combustion engine, the motor and the engaging/disengaging device being driven by a working fluid. The hybrid vehicle further includes a clutch which carries out the engagement/disengagement between a first drive shaft through which a driving force of an engine is transmitted and a second drive shaft through which a driving force of the motor is transmitted to wheels, an electrically-operated first pump capable of supplying hydraulic oil to a relative rotational force generator of the motor and the clutch, a mechanical second pump which is driven by the engine and which is capable of supplying the hydraulic oil to the clutch, and a solenoid selector valve for selectively switching the source of supply of the hydraulic oil to the clutch to the first pump or the second pump.
