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.

Abstract: A method, a system, a terminal and a server for switching from a video live stream to video-on-demand data are provided. The method includes: sending, by a terminal, a video acquisition request for a target video to a server; acquiring, by the server, video data of the target video from a live stream of the target video in response to the video acquisition request, and storing the acquired video data of the target video; sending, by the terminal, a video editing request for the target video to the server; performing, by the server, non-linear editing on the video data of the target video in response to the video editing request; and storing, by the server, the edited video data as video-on-demand data of the target video.
