  • Patent number: 10059209
    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.

  • Publication number: 20180238449
    Abstract: A vehicle includes: a power receiving part; an operating part configured to allow a driver to select a parking lock state or a non-parking lock state; a parking lock device configured to be mechanically switchable between the parking lock state and the non-parking lock state; and a controller configured to control the parking lock device according to an electric signal output from the operating part. While the power receiving part is receiving electric power with the parking lock device being in the parking lock state, the controller: sends a first command that commands stop of power feeding to the power receiving device to the power feeding device when the non-parking lock state is selected; and controls the parking lock device so that the parking lock device is switched from the parking lock state to the non-parking lock state after electric power has decreased to a predetermined value or lower.

  • Patent number: 9902390
    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.

  • Patent number: 9725007
    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.
