本发明系关于一种双向分配、充电及贩卖系统，其准许一用户将一或多个部分或完全放电之可携式电能存储器交换成相当数个经充电可携式电能存储器。该系统包含经可通信地耦合至至少一个双向分配系统控制器且耦合至一配电网的若干个充电模块，每一充电模块具有一专用电力转换器。在接收到一经放电可携式电能存储器之后，该控制器旋即证实存储于由该经放电可携式电能存储器携载之一非暂时性存储媒体中之一制造商识别符及一用户识别符。回应于一成功鉴认及证实，该控制器将一经充电可携式电能存储器施配给该用户。

A two-way distribution, charging, and vending system permits a subscriber to exchange one or more partially or completely discharged portable electric energy storage devices for a comparable number of charged portable electric energy storage devices. The two-way distribution, charging, and vending system includes a number of charging modules, each with a dedicated power converter, communicably coupled to at least one two-way distribution system controller and to a power distribution grid. Upon receipt of a discharged portable electric energy storage device, the at least one two-way distribution system controller validates a manufacturer identifier and a subscriber identifier stored in a nontransitory storage media carried by the discharged portable electric energy storage device. Responsive to a successful authentication and validation, the at least one two-way distribution system controller dispenses a charged portable electric energy storage device to the subscriber.
