Abstract: An electric drive vehicle which is capable of performing a bidirectional voltage conversion between two DC power supplies and a rotary electric machine, and a connection switch between a series connection and a parallel connection of the two power supplies with respect to the rotary electric machine. The electric drive vehicle can supply electric power without a delay in response to a change in a load request.

Abstract: SOC of an electrical power source made consistent with a traveling state. An electrical power source system is provided with a plurality of electrical power sources, and drives a motor generator. At the time of traveling, electrical power exchange for a plurality of electrical power sources is controlled by a converter based on temperature of the electrical power sources and travel information or route information, and SOC of one electrical power source, among the plurality of electrical power sources, is controlled to a specified value.

Abstract: A converter is capable of using two power sources located on a first side by switching connection of the two power sources between series connection and parallel connection. Under certain conditions, such as when a detected atmospheric pressure is lower than a predetermined value, frequency of use of the two power sources in series connection is reduced in the converter. It is thereby possible to prevent generation of excessive voltage by the power converter.

Abstract: An electric vehicle includes a voltage converter, a temperature sensor, and a control unit. The voltage converter performs bidirectional voltage conversion between an output electric path and one or both of first and second batteries, while allowing switching of an operating mode between a serial operating mode in which the first and second batteries are connected in series relative to the output electric path, and a parallel operating mode in which the first and second batteries are connected in parallel. The temperature sensor detects a temperature of each battery. The control unit switches the operating mode of the voltage converter. When the temperature of one battery is equal to or larger than a predetermined upper threshold value A, or equal to or smaller than a predetermined lower threshold value B, the control unit switches the operating mode of the voltage converter to the parallel operating mode.

Abstract: When the accelerator and the brake pedal are simultaneously depressed, braking occurs with drive force being produced. This increases the amount of heat produced by a friction braking device. Therefore, when the accelerator and the brake pedal are simultaneously depressed (S100: Yes), the range of use for a regenerative braking device is increased by expanding the regenerative braking limit (S101), thereby decreasing the range of use for the friction braking device, so that the produced heat to be suppressed. As a result, it is possible to simplify the friction braking device and eliminate the need to install a cooling mechanism equipped a high cooling performance.
