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.

Claim (Index 1):
A flexible-grouping current sharing method for a bus sharing charger system, comprising steps for group distribution of a specific charging combination of:\n Step ( 1 ) judging whether a group distribution prophase address sequencing command is triggered by a charging module; Step ( 2 ) starting performing group distribution after the group distribution prophase address sequencing command is triggered; Step ( 3 ) initializing group distribution information on a power distribution unit (PDU) inside the charging module; Step ( 4 ) executing an address sequencing command by all charging modules on a CAN bus; sequencing address numbers of all the charging modules determined on a basis of a single production date, production quantity and production site on a bar code; uploading a complete symbol to a charging control unit CCU by all the charging modules after completing; step ( 5 ) judging whether the charging control unit (CCU) sends a group distribution command to the power distribution unit (PDU), if yes, continuing the step ( 5 ); if no, jumping to a step ( 12 ); step ( 6 ) receiving and analyzing a group distribution data frame of the PDU issued by the CCU by each of the charging modules, understanding which PDU combination to join; and modifying group distribution information in current sharing frames to be sent; step ( 7 ) sending and broadcasting the current sharing frames by each one of all the charging modules; filtering out-group current sharing data according to the group distribution information in the current sharing frames; refreshing a new charging module address table in groups according to the address numbers in the step ( 4 ) to obtain address numbers of each group of main charging modules; step ( 8 ) refreshing a group distribution status symbol of current share regulating frame each group of the main charging modules to be OK; refreshing a group distribution status of the data frame to be OK after received by the charging modules, meanwhile, updating a CCU group distribution complete symbol by the charging modules; step ( 9 ) inquiring group distribution status of the PDU uploaded via each group of the charging modules by a CCU; wherein if the group distribution status is in accordance with a group distribution object of the PDC, the CCU allows each specific charging group to start up to work; step ( 10 ) regularly sending the current share regulating frame by each group of the main charging modules to regulate share current of the charging modules in groups, and emptying current sharing data information in a present group; step ( 11 ) after receiving current sharing frames in each group by the charging modules, refreshing current sharing data of a corresponding charging module; wherein out charging module current sharing data which is filtered stays out of current sharing in a current group; step ( 12 ) implementing within-group current sharing among each charging groups; and completing charging operation of different charging battery.
