    Abstract: An electrically excited motor drive system is integrated with an on-board charger (OBC), so that a power supply circuit that is in an electric vehicle and that is configured to drive an electrically excited motor can be integrated with an OBC of a dual active bridge (DAB) type. When a control component controls a switch circuit, the electrically excited motor drive system obtained after integration can separately implement a function of the power supply circuit or a function of the charging circuit in different working modes. In addition, when the electrically excited motor drive system is in different working modes, some circuits are further reused through time division. This addresses a problem that the power supply circuit cannot be integrated with the OBC of the DAB type, to reduce circuit complexity and costs of the electric vehicle.

  • Patent number: 11909232
    Abstract: Disclosed herein is a system comprising: a power source apparatus; a first device and a second device associated with a user; and a server computer. The second device couples to the power source apparatus. The power source provides status information to the first device. The first device sends a communication to the power source apparatus via an application operating on the first device, wherein the communication provides a charging instruction to the power source device and the instruction is based on the status information received from the power source. The power source apparatus charges the second device based on the charging instruction received at the power source apparatus from the first device. The server communicates with the first device to maintain a database relating to at least one of the power source apparatus and the second device and comprising status information.

  • Patent number: 11881788
    Abstract: In a DC/DC converter, in first power transmission in which power is transmitted from a first DC power source to a second DC power source, on/off drive of a positive electrode-side switching element and a negative electrode-side switching element is stopped in a third bridge circuit on the power-receiving side. When a power transmission amount by the first power transmission is smaller than a first reference value, a control circuit lowers the switching frequency of the switching elements of a first bridge circuit and a second bridge circuit on the power-transmitting side and a fourth bridge circuit on the power-receiving side, compared with when the power transmission amount is equal to or greater than the first reference value.

  • Patent number: 11870353
    Abstract: A power supply unit provides power to a common output node. The power supply unit includes a first power conversion block electrically coupled to convert the electrical power input to a first output power supply share supplied to the common output node. The first power conversion block is configured to decrease output voltage from the first power conversion block based on output current from the first power conversion block reaching a rated current level. A second power conversion block is electrically coupled to convert the electrical power input to a second output power supply share supplied to the common output node. The second power conversion block is configured with a predesignated open circuit voltage setting and is further configured to contribute the second output power supply share to the common output node based on the output voltage at the common output node decreasing to the predesignated electrical voltage setting.

  • Patent number: 11833987
    Abstract: A hybrid power module is provided. The power module is associated with a truck having a lift gate. The power module includes a super capacitor comprising a bank of capacitors, with the super capacitor being in electrical communication with an alternator of the truck. The power module also includes a battery, a switch, a DC/DC boost converter, and electrical wiring. The electrical wiring connects the capacitor bank and first battery to the switch, and further connects the switch to a motor for the lift gate. The super capacitor and the first battery are positioned in parallel, with the super capacitor and the first battery residing proximate the lift gate. The super capacitor contains enough energy to power the electric motor for the lift gate through at least two operating cycles without the battery, protecting the lift gate if the battery goes weak.
