A control apparatus includes: a movement information acquisition unit configured to acquire information indicating a usage period of a mobile object and a movement distance or a destination of the object to be ensured within the usage period; and a restriction unit configured to restrict a power amount from a battery included in the object to an outside of the object so as to ensure that the object can move the movement distance or move to the destination within the usage period. A method includes: acquiring information indicating a usage period of a mobile object and a movement distance or a destination of the object to be ensured within the usage period; and restricting a power amount from a battery included in the object to an outside of the object so as to ensure that the object moves the movement distance or moves to the destination within the usage period.

Control apparatus, mobile object, method, and computer-readable storage medium

With a charging control apparatus, a current SOC and target SOC of a battery and an electricity cost per unit power of charging equipment are acquired. Then, a charging schedule is set that lowers the deterioration acceleration of the battery by making a comparison between the current SOC and the target SOC, while considering the electricity cost.

Charging control apparatus, moving body, charging control system, and charging control method

Scheduled usage of an electric moving body that moves using a battery as a power source is acquired; a necessary remaining capacity that is a charging state necessary for the scheduled usage is acquired; and if the necessary remaining capacity is not reached by a start timing of the scheduled usage, a charging plan set in advance prior to the acquired scheduled usage is changed in a manner that the necessary remaining capacity is reached by the start timing of the scheduled usage.

Charging control method for electric moving body, and electric moving body

With a charging control apparatus, first, a chargeable amount is acquired. Then, the charging control apparatus calculates a minimum SOC that is the lowest SOC needed by the vehicle for the following travel. Then, the charging control apparatus sets a target SOC that restricts deterioration of the battery and is greater than or equal to the minimum SOC. Alternatively, the charging control apparatus sets a target charging amount that restricts deterioration of the battery and is less than or equal to the chargeable amount.

A battery consumption amount from when an electric vehicle departs a base charging location to when the electric moving body has returned to the base charging location is set as a consumption amount of one day, and an estimated consumption amount of one day is calculated based on the consumption amounts of the past n days. A value obtained by adding the estimated consumption amount and a margin to a lower limit remaining capacity determined in advance by a user is set as a charging recommendation threshold value. When the remaining capacity of the battery drops below the charging recommendation threshold value, a notification prompting charging of the battery is transmitted to an on-board HMI of the electric moving body or a terminal of the user.

A charge control device for charging a battery with electric power supplied from an external power supply includes: an external power supply information acquisition unit that acquires external power supply information including a voltage of the external power supply; a battery information acquisition unit that acquires battery information including a temperature, a voltage, and an electric current of the battery; a power consumption acquisition unit that acquires an amount of electric power supplied from the battery to an auxiliary device as a power consumption amount; and a charge time estimation unit that estimates a charge time of the battery. The charge time estimation unit acquires an initial value of a state of charge of the battery based on the battery information, and estimates the charge time based on the battery temperature, the external power supply information, the power consumption amount, and the initial value of the state of charge.

Charge control device and charge control method

An air conditioner includes: a secondary battery which is chargeable with electric power supplied from outside of a vehicle and store the electric power for running the vehicle; an air conditioning unit which performs air conditioning in a vehicle interior of the vehicle; a timer for managing a time for operating the air conditioning unit; and a control unit which sets a charging prohibition time period for prohibiting charging of the secondary battery for a time period set by a user. In a case in which electric power is supplied from outside of the vehicle and an operation of the air conditioning unit is set by the timer during the charging prohibition time period, the control unit operates the air conditioning unit using the electric power supplied from outside of the vehicle without charging the secondary battery with the electric power, and in a case in which electric power is supplied from outside of the vehicle and an operation of the air conditioning unit is set by the timer during a time period other than the charging prohibition time period, performs the charging of the secondary battery with the electric power and operates the air conditioning unit using the electric power supplied from outside of the vehicle.

Air conditioner, air conditioning control method, and program

A vehicle control system includes: a vehicle near field communication unit that communicates via a near field communication path; a vehicle network communication unit that communicates via a global communication path; a control ECU; a transmission control unit that transmits control commands received by the vehicle near field communication unit and the vehicle network communication unit to the control ECU that controls actions of the vehicle; and a control command detection unit that detects whether or not there are a plurality of same control commands received within a prescribed time. When the control command detection unit detects a plurality of control commands received within the prescribed time, the transmission control unit transmits the control commands in order according to a prescribed priority order, and the control ECU processes the control commands received from the transmission control unit in a received order to control the actions of the vehicle.

Vehicle control system

Provided s a non-contact power transmission system with which it is possible to individually detect the position of a receiving unit with respect to a transmission unit, even if there are positions at which the same microvoltage values are indicated, even if the distance differs, due to the shape of the transmission coil of the transmission unit and the receiving coil of the receiving unit. At a position at which the position differential value of the detected microvoltage exceeds a zero value, said positions set to the initial position (+xint) of the movement displacement of the vehicle, and the movement displacement on the basis of vehicle velocity is calculated to a position (+xc) at which the microvoltage value characteristics can be used from said initial position to (+xc to 0).

Non-contact power transmission system

Provided is a non-contact power transmission system with which it is possible to ion a primary coil and a secondary coil more accurately. A vertical distance estimation unit estimates the vertical distance between the center of the primary coil and the secondary coil on the basis of a voltage value detected by a voltage detector. A horizontal distance estimation unit estimates the horizontal distance between the center of the primary coil and the center of the secondary coil on the basis of the vertical distance estimated by the vertical distance estimation unit, the voltage value detected by the voltage detector, and the voltage value-distance information stored on the memory.

A server configured to aggregate height information of a primary coil of each charging station from a road surface is provided. When a signal expressing that charging is performed at the charging station at a desired position has been received from a secondary side control unit of an electric vehicle through a secondary side communications device of the electric vehicle, the server is configured to transmit to the secondary side control unit of the electric vehicle, the height information of the primary coil of the charging station at the desired position from the road surface.

In a non-contact power transmission system, the radial distance of a power reception coil relative to a power transmission coil is detected on the basis of the weak voltage value corresponding to the amount of weak power received by the power reception coil, and moreover the moving amount is detected on the basis of the change in level of the detected weak voltage value and furthermore, the moving direction is detected. Thus, the position (distance) of the power reception coil relative to the power transmission coil is detected.

Based on a vehicle speed Vv, a vehicle moving amount cvp is calculated from cvp=&#x222b;Vv&#xb7;dt. From the Pythagorean theorem, expressions y+x=raand y+(cb&#x2212;x)=cvpare held. From these two expressions, an ECU of a non-contact power transmission system obtains x and y. In the expressions, y is a distance in a horizontal direction from a power transmission coil, x is a distance in a vertical direction from the power transmission coil, and ra is a distance from the power transmission coil at a two-dimensional current position and is obtained in advance from a correspondence relation between the distance and the intensity of a power transmitted from the power transmission coil.
