A vehicle control system may, during a deactivated state of the vehicle, generate a wake up signal, and responsive to a current or voltage associated with the wake up signal being outside a predetermined range, activate an ignition relay of the vehicle for a predefined period of time. The vehicle control system may further, responsive to a request to activate the vehicle, activate the ignition relay.

Disclosed herein are representative embodiments of methods, apparatus, and systems for charging and discharging an energy storage device connected to an electrical power distribution system. In one exemplary embodiment, a controller monitors electrical characteristics of an electrical power distribution system and provides an output to a bi-directional charger causing the charger to charge or discharge an energy storage device (e.g., a battery in a plug-in hybrid electric vehicle (PHEV)).

The controller can help stabilize the electrical power distribution system by increasing the charging rate when there is excess power in the electrical power distribution system (e.g., when the frequency of an AC power grid exceeds an average value), or by discharging power from the energy storage device to stabilize the grid when there is a shortage of power in the electrical power distribution system (e.g., when the frequency of an AC power grid is below an average value).

A system includes an on-board charger that receives energy from an external power source and a battery having a state of charge (SOC) and a battery temperature. The system also includes a battery heater that converts electrical energy into thermal energy (heat) for increasing the battery temperature. The system also includes a battery management system (BMS) that determines or detects a current SOC of the battery and a current battery temperature. The system also includes an electronic control unit (ECU) coupled to the on-board charger and to the BMS. The ECU controls the on-board charger to distribute energy to the battery and to the battery heater to cause the SOC to remain above a SOC threshold and to cause the battery temperature to remain above a battery temperature threshold based on the current SOC and the current battery temperature.

There is provided a charging device for a vehicle, which carries out timer charging in which the charging device, is set in a standby state without charging until charging start time comes when the charging start time is set. The charging device includes a charger that charges an electrical storage device of the vehicle with electric power supplied from a device outside the vehicle, a cable lock mechanism (260) that locks a charging cable in a state where the charging cable is connected to an inlet, and an electronic control unit (170) that determines whether to carry out timer charging or carry out instant charging without carrying out the timer charging on the basis of a state of a switch associated with operation of the cable lock mechanism (260).

A battery management system thermally conditions a battery assembly prior to a determined upcoming time or the battery assembly's arrival at an upcoming location, and selects a source of the power used for the thermal conditioning.

A system and a method for managing a charging station allow charging a battery of a connected autonomous electric vehicle for carrying passengers in a controlled environment. A controller connected to the charging station determines and modulates a charging rate with which the charging station charges the battery based on a duration between a start of charging the vehicle and a forecasted time of start of duty mode of the vehicle. The duration is determined by the controller based on a forecasted passenger load as a function of time.

The disclosure includes a system and method for charging and discharging a Plug-in Electric Vehicle (“PEV”). The method may include determining that first event data describes a Renewable Energy Output Control event (“REOC event”) including instructions directing a Renewable Energy Power Generation facility (“REPG facility”) to not output power to a power grid during a time period specified by the REOC event. The method may include the REPG facility charging a battery system included in a PEV during the REOC event. The battery system may be coupled to the REPG facility via a coupling that does not including the power grid. The battery system may be charged by the REPG facility via the coupling with power generated by the REPG facility during the first duration of the REOC event so that the REPG facility continues to generate power during the REOC event.

The disclosure includes a system and method for determining a departure time for a Plug-in Electric Vehicle (“PEV”). The method may include analyzing power meter data to determine that a connector of a control device is coupled to an inlet of the PEV. The method may include charging a battery set of the PEV with electricity. The method may include determining a next day of a next journey for the PEV based on clock data provided by a clock. The clock data may describe time information describing a present day and a category of the next day. The method may include analyzing history data associated with the category of the next day to determine a habitual time associated with the category of the next day. The method may include estimating that a departure time for the next journey is substantially equal to the habitual time.

A control apparatus is used for an electric electric vehicle. The electric vehicle charges a storage battery with electric power that is supplied while traveling in a power supply lane that is a travelling road on which contactless power supply is able to be performed. The control apparatus for the electric vehicle includes a charging control unit and a range changing unit. The charging control unit controls charging of a storage battery of an electric vehicle such that a charge amount of the storage battery falls within a target range that is a preset range. The range changing unit changes at least one of an upper limit value and a lower limit value of the target range based on a state of the electric vehicle.

A vehicle control device configured to control charge and discharge of a battery mounted on a vehicle includes an obtaining unit configured to obtain a parking time of the vehicle, a setting unit configured to derive a charge voltage of the battery based on at least the parking time obtained by the obtaining unit, and a voltage control unit configured to control charge of the battery based on the charge voltage of the battery derived by the setting unit when the vehicle is traveling.
