  • Patent number: 11318858
    Abstract: An intelligent electric-vehicle charging station is provided. The charging station includes at least one charger. Each charger includes at least one power conversion unit and at least one charging terminal. Each power conversion unit includes an alternating-current power distribution module, a plurality of rectification modules, a switch matrix and a power controller. The alternating-current power distribution module supplies power to each power conversion unit and the at least one charging terminal. The rectification modules are divided into a plurality of groups of modules. The plurality of groups of modules is controlled, through the switch matrix, to be connected to a plurality of direct-current output circuits. Each direct-current output circuit is connected to one charging terminal. The switch matrix switches each group of modules in the plurality of direct-current output circuits according to a control instruction of the power controller.

  • Patent number: 11267361
    Abstract: Provided herein are a system and method for ordered charging management of a charging station. The system includes a charging station control-management device, a charging pile monitoring device and a system platform server. The system platform server is configured to send a power capacity of the charging station to the charging station control-management device corresponding to the charging station. The charging pile monitoring device is configured to collect an operating parameter of a charging pile corresponding to the charging pile monitoring device and to send the operating parameter to the charging station control-management device. The charging station control-management device is configured to determine whether the charging station has a power headroom according to the power capacity and the operating parameter of all charging piles at the charging station after receiving a charging request sent by the charging pile monitoring device.

  • Patent number: 9257690
    Abstract: A battery locking device for a new energy vehicle including: a battery compartment fit for a battery, the battery compartment being provided with a battery inlet; and a battery clamping device provided on the battery compartment and controlled by a linkage mechanism. Since the battery clamping device is controlled by the linkage mechanism, during the mounting or removing of the battery, the battery can be integrally clamped or released by merely operating an operating end of the linkage mechanism. Compared with the prior art in which the battery is fixed through bolts, the battery can be integrally clamped or released by the battery locking device through a single operation, which greatly simplifies the disassembling or assembling process of the battery and reduces the time required for replacing the battery. A new energy vehicle provided with the above battery locking device has the same advantages.
