Abstract:
An electric vehicle comprises an electric motor which generates a driving power for driving a wheel; and a battery case accommodating a plurality of batteries storing DC power to be supplied to the electric motor, in a battery space in an interior of the battery case, wherein the battery case has a shape which covers the electric motor above and forward.
Abstract:
An air conditioner for a vehicle has a compressor, a radiator, a first pressure reducer, a gas-liquid separator, a second pressure reducer, an exterior heat exchanger, an intermediate pressure refrigerant passage, a switching device, and a controller. The controller operates the switching device to switch from a refrigerant circuit of a two-stage compression mode to a refrigerant circuit of a single-stage compression mode when a compressor stop signal is output in the two-stage compression mode. The single-stage compression mode is a mode that blocks at least a flow of an intermediate-pressure refrigerant into the intermediate pressure refrigerant passage and makes refrigerant remained in the intermediate pressure refrigerant passage to flow out of the intermediate pressure refrigerant passage. The controller stops the compressor after controls the compressor to continue operating for a specified time in the single-stage compression mode. The controller restarts the compressor when the compressor stop signal is canceled.
Abstract:
A method of providing coolant to an electric battery for powering a drive train of an electric vehicle is provided. The method includes providing coolant from a coolant source off-board the electric vehicle at a first rate to cool the electric battery during recharging of the electric battery; and circulating coolant through a coolant loop on-board the electric vehicle at a second rate less than the first rate to cool the electric battery after the recharging of the electric battery.
Abstract:
A hybrid electric vehicle drive apparatus has a setting portion for setting a limit value of a driving torque that a motor outputs when driving a hybrid electric vehicle by the power of the motor only, based on a maximum torque that the motor enables to output and a starting torque used to start an internal combustion engine by the motor. The setting portion sets the limit value to a first value and sets the limit value to a second value which is greater than the first value when a vehicle speed of the vehicle does not increase even though an accelerator pedal position degree increases while the vehicle is being driven only by the motor.

Abstract:
In an electric vehicle, an automatic transmission is provided between a differential unit and drive wheels. The differential unit includes a motor-generator and a power split device, and the motor-generator is cooled by lubricant of the automatic transmission. A battery charger is operable to charge a power storage device using a power supply outside the vehicle. When the temperature of the lubricant is lower than a predetermined temperature upon execution of charging of the power storage device using the charger, and the automatic transmission is in a neutral state, or a power cutting-off state, the controller rotates the motor-generator of the differential unit so as to perform warming control for raising the temperature of the lubricant.

The invention provides a thermal management system for a fuel cell, a fuel cell system and a vehicle equipped with the fuel cell system. The thermal management system for a fuel cell comprises: a cooling system (100) for recovering the waste heat produced by the fuel cell system, a heat supply system (15) connected with the cooling system (100) to supply heat using the waste heat recovered by the cooling system (100). The fuel cell system comprises a fuel cell stack and the aforementioned thermal management system for a fuel cell. The vehicle comprises the fuel cell system, wherein the thermal management system for a fuel cell reduces the temperature of each component of the fuel cell system by cooling the component using the cooling system (100) and recovers the waste heat generated by the fuel cell system, and the heat supply system (15) supplies heat by using the waste heat recovered by the cooling system as a heat source, thus effectively using the heat generated by a fuel cell stack, the heat of exhaust gas and the heat generated by electrical accessories during the running process of the fuel cell stack and consequentially reducing the running cost of the fuel cell.
Abstract:
A system for operating a positive temperature coefficient (PTC) heater in a fuel cell vehicle includes a fuel cell stack and a PTC heater generating heat when supplied with an electric current. A controller is configured to check a key-start state of the vehicle and determine whether or not an outdoor temperature is lower than a reference temperature. If it is determined that the vehicle is key-started so as to activate the fuel cell stack, and the outdoor temperature is lower than the reference temperature, the controller supplies electrical energy generated by the fuel cell stack to the PTC heater, thereby driving the PTC heater.
Abstract:
A vehicle temperature control apparatus for controlling temperature of a temperature control object, which is at least one of inside air of a vehicle compartment and a vehicle component, includes a heat capacitive element capable of storing heat, a refrigeration cycle in which heat is absorbed from a low temperature side and is dissipated to a high temperature side, a heat exchanger that causes the heat capacitive element to exchange heat with refrigerant of the refrigeration cycle, and a heat dissipation portion which dissipates heat in the refrigerant of the refrigeration cycle to the temperature control object. Thus, a temperature control by using the heat capacitive element can be effectively performed.

A warm-up control device for a vehicle includes a battery supplying electricity to a motor that drives a vehicle and can be charged with a current supplied from the exterior of the vehicle, and a heater generating heat that warms up the vehicle by the above current. The warm-up control device further includes a temperature acquisition unit acquiring a temperature of the battery, and a current distribution control unit increasing a heater supply current supplied to the heater as the temperature of the battery decreases. This can effectively utilize energy from an external power source for the charging and warming-up, thus improving the energy saving performance.
