Abstract: A system and method for supplying hydrogen gas, and a hydrogen fuel cell system are provided to solve inconvenience caused by the requirement for replacing a hydrogen storage container during hydrogen gas supplement. The system for supplying hydrogen gas includes a hydrogen storage unit, a hydrogen conveying unit and a charging device connected to the hydrogen storage unit, where the charging device includes a charging opening matched with a hydrogen gas infusing unit. It may be noted that according to the solution provided by the embodiments of the present disclosure, when hydrogen gas needs to be supplemented, an external infusing device may be used to infuse hydrogen gas to the hydrogen storage container in the hydrogen storage unit through the charging opening, which avoids replacement of the hydrogen storage container during an entire infusing process, and makes an intensive hydrogen gas supplement process more convenient and faster.

Abstract: A charging pile system comprising a system input bus, charging pile circuit groups, a controller, a power allocation unit, and charging terminals. The power allocation unit comprises a first switch group, a second switch group, and a third switch group. The first switch group comprises first switching devices, the second switch group comprises second switching devices, and the third switch group comprises third switching devices. The first switching devices are coupled to respective output ends of the charging pile circuit groups so as to configure at least two idle charging pile circuit groups to be coupled either in series or in parallel to provide a first output. Each of the second switch group and the third switch group is configured to couple an input end of any of the charging terminals in series or in parallel to provide a second output to the charging pile circuit groups.
