  • Publication number: 20200091794
    Abstract: An electric pump includes an impeller and a brushless motor including a rotor, a stator, a circuit board, and a coil terminal. The rotor is coupled to the impeller. The stator includes a plurality of stator coils circumferentially disposed around or within the rotor and include a first stator coil. The circuit board extends in a plane crossing with an axial direction of the rotor and includes an electric circuit. The coil terminal electrically couples the first stator coil and the electric circuit of the circuit board. The coil terminal extends from the circuit board and is disposed outside or inside the first stator coil in the radial direction. The coil terminal includes a coil-side end positioned further away from the circuit board in the axial direction than at least a portion of the first stator coil. The coil terminal is coupled to the first stator coil via the coil-side end.

  • Publication number: 20200088182
    Abstract: An electric pump includes a first housing member, a second housing member, and a partition. The first housing member includes a first support surface and a first seal surface. The second housing member includes a second support surface and a second seal surface. The partition is directly held between the first support surface and the second support surface to form a pump chamber with the first housing member and to form a motor chamber with the second housing member. The motor chamber houses a motor that includes a stator and a rotor. The pump chamber houses an impeller. The partition supports a bearing for holding a rotation shaft coupled to the rotor and the impeller. The first seal surface and the second seal surface directly hold a seal member therebetween.

  • Publication number: 20200076224
    Abstract: A charge controller, which controls a charging process for charging a battery mounted on a vehicle by connecting a charging connector of a charger that is installed outside the vehicle to a charging inlet of the vehicle, includes: a controller discriminating whether a cooling mechanism of the charging connector is provided on a charger side before starting the charging process, operating the cooling mechanism of the charging connector if the cooling mechanism of the charging connector is provided, and operating a cooling mechanism of the charging inlet that is provided on a vehicle side if the cooling mechanism of the charging connector is not provided.

  • Publication number: 20190308519
    Abstract: A vehicle is configured to perform plug-in charging for charging a battery mounted in the vehicle with electric power supplied through a charging cable from a charging stand. The vehicle includes: an inlet to which a connector of the charging cable is connectable; and an ECU configured to control a supply current from the charging stand such that the supply current does not exceed a maximum allowable current. The ECU is configured to obtain specific information as to whether or not the charging stand is provided with a cooling mechanism for cooling the connector and the inlet. The ECU is configured to set the maximum allowable current to be higher when the charging stand is provided with the cooling mechanism than when the charging stand is not provided with the cooling mechanism.

  • Patent number: 10393048
    Abstract: A control device is configured to perform, when it is estimated that a combustion fluctuation increases, estimation related to an ignition delay for initial flame generated from a discharge spark and an air-fuel mixture containing fuel spray injected by intake stroke injection. When it is estimated that the ignition delay for the initial flame is increased from that before the increase in the combustion fluctuation, an injection amount in expansion stroke injection is reduced in a next time cycle. When it is estimated that the ignition delay for the initial flame is reduced from that before the increase in the combustion fluctuation, the injection amount in expansion stroke injection is increased in a next time cycle.

  • Patent number: 10066562
    Abstract: In a catalyst warming-up control, a first time injection is performed by an injector in an intake stroke. A second time injection is performed with an amount smaller than the first time injection in an expansion stroke after a compression top dead center. In the catalyst warming-up control, an interval from the start of the ignition period of an spark plug to the completion of the second time injection is controlled by the ECU so that the initial flame generated from an air-fuel mixture containing the fuel spray injected by the first time injection is brought into contact with the fuel spray injected by the second time injection.
