Abstract:
A warm-up apparatus for a vehicle including a system which charges a battery by using an external power supply is provided. The warm-up apparatus includes a heater for warming up, a current detector, a voltage detector and a resistance changer. The heater is mounted in the vehicle and produces heat by receiving electric power from the external power supply. The current detector detects an allowable current value of the external power supply. The voltage detector detects an output voltage value of the external power supply. The resistance changer changes an electric resistance value of the heater based on the allowable current value detected by the current detector and the output voltage value detected by the voltage detector.
Abstract:
The present invention provides an apparatus and method for air conditioning a vehicle interior using a battery charge control of an electric vehicle, which can improve the cooling/heating performance by setting a start-up time of the electric vehicle and supplying heat generated from a battery during charge and its latent heat to the vehicle interior during initial start-up of the vehicle.
Abstract:
A battery temperature adjustment apparatus including a battery, a temperature adjustment section configured to operate by power supplied from an external power source or the battery and adjust a temperature of the battery by heating or cooling, a detection section configured to detect a temperature of the battery, and a control section configured to change an operating condition or an operating state of the temperature adjustment section according to whether or not the external power source to supply power to the battery is electrically connected, and in a case where the external power source is not electrically connected, restrict the operation of the temperature adjustment section so as to reduce power consumed in the battery as compared to a case where the external power source is electrically connected.
Abstract:
A method for charging a thermal storage device of a thermal storage heat pump system in a vehicle is provided. The method includes comparing an actual temperature of the thermal storage device to a target temperature, and an actual charge time to an available charge time, where the comparing is performed by a controller. The target temperature may be based upon ambient air temperature and ambient air humidity. The actual charge time is the time it takes to charge the thermal storage device to the target temperature. The available charge time is the difference between the current time and an intended departure time. When the target temperature is greater than the actual temperature, and the available charge time is equal to or greater than the actual charge time, the controller may charge the thermal storage device until the actual temperature is equal to the target temperature.
Abstract:
A charger includes a charging cable and a charging connector. A heater is configured to heat the charging connector using electric power supplied through the charging cable. A state determining device is configured to detect a charge state of a vehicle-mounted battery and to determine whether a heating condition to heat the charging connector is met. A heating controller is configured to control heating performed by the heater based on a determination made by the state determining device. The heater is able to be switched into a post-charge heating state in which the heater heats the charging connector after completion of charging of the vehicle-mounted battery. The heating controller switches the heater into the post-charge heating state and controls heating performed by the heater when the state determining device detects that charging of the vehicle-mounted battery is completed and determines that a heating condition is met.
Abstract:
In a first condition, the sum of discharging power from a first battery stack and discharging power from a second battery stack is limited in accordance with the sum of a limit value of discharging power from the first battery stack and a limit value of discharging power from the second battery stack. In a second condition, electric power of the battery stacks is limited in accordance with either the limit value of discharging power from the first battery stack or the limit value of discharging power from the second battery stack.

Abstract:
A system and method for charging a plug-in electric vehicle with an external power source, even when the overall power requested by the plug-in electric vehicle exceeds the overall power available from the external power source. In an exemplary embodiment, a method determines the overall power requested by one or more vehicle systems, and then compares that to the overall available power from the external power source. If the overall requested power exceeds the overall available power, then the power from the external power source is allocated or apportioned to the different vehicle systems according to an allocation process that may consider factors like predetermined priorities and current vehicle conditions.
