  • Patent number: 10447057
    Abstract: A matrix power distribution charging system includes at least two DC modules and a plurality of PDUs, wherein the DC modules and the PDUs are respectively connected to a CCU; wherein a power matching method includes steps of: sending orders to the DC modules by the CCU after the matrix power distribution charging system is turned on, so as to order the DC modules to output different constant voltage values; comparing the front end voltages of the switch devices with the constant voltage values outputted by the DC modules for determining a corresponding relation between the switch devices and the DC modules; finally, logically computing by the CCU according to an actual power requirement of the parking space and sending control orders to the PDUs for a certain DC module output combination, in such a manner that the PDUs correctly outputs a certain power.

  • Publication number: 20180198288
    Abstract: An object of the present invention is to provide a flexible-grouping current sharing method for a bus sharing charger system. By analyzing information of the charger system (including a power distribution unit (PDU) and a charging module), a charging control unit (CCU) automatically distributes a certain amount of PDU and charging modules for serving as a specific charging group to achieve charging operation to a charging object (battery). During the process, each of the charging modules in the groups automatically achieves within-group current sharing by data filtering, and out-group module is not involved in the current sharing. When the capacity or quantity of the charging objects (battery) changes, the system distributes one or more specific charging group again to achieve charging operation on different charging objects (battery) simultaneously or with time interval.

  • Patent number: 10000130
    Abstract: A charging management system (CMS) and a charging management method for a charger of an electric vehicle are provided. The CMS includes a charger grid micro-dispatching system (CGMS) module, a charger battery management system (CBMS) module, a charger vehicle-dispatching management system (CVMS) module, a charger network management system (CNMS) module, and a charger charging management system (CCMS) module. An intelligent safety redundant strategy and a fault recording strategy are introduced, and multiple related parameters of a battery management system (BMS) are built in the CBMS module, so as to realize an intelligent active protection during charging the electric vehicle. Meanwhile, through analyzing the BMS and characteristic data of a power battery, cooperating with the CCMS module, adopting a multi-dimension data analyzing and controlling strategy, and outputting an optimized flexible curve current based on battery charging, life time of the battery is lengthened.

  • Publication number: 20170021736
    Abstract: A charger with active protection function includes: a power conversion module group, a monitoring unit and an output module group; wherein the power conversion module group is respectively connected with the monitoring unit and the output module group; the monitoring unit is connected with the output module group; the charger with active protection function is connected with an electric vehicle via the output module group to charge the electric vehicle; and when the charger with active protection function is connected with the electric vehicle, the charger with active protection function communicates with BMS of a vehicle via the output module group. The output module group obtains real-time charging data of the electric battery of the BMS. The output module group combines the warn value and threshold value to judge whether the BMS and the power battery are in abnormal condition during charging process.
