Title:
BATTERY CHARGING SYSTEM AND ELECTRICAL VEHICLE CHARGING STATION COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/000951
Kind Code:
A1
Abstract:
A battery charging system (10), comprising one or more battery charging units, each battery charging unit comprising: a charging module (110) configured to adapt to charge a plurality of battery packs (B1-Bn); a power switching module (120) comprising a plurality of charging channels, wherein each of the plurality of battery packs (B1-Bn) establishes a charging connection with the charging module (110) via the respective corresponding charging channel; a communication switching module (130) comprising a plurality of communication channels, wherein each of the battery packs (B1-Bn) establishes a communication connection with the charging module (110) via the respective corresponding communication channel; and a local monitoring module (140) configured to connecting to the power switching module (120) and the communication switching module (130) in each battery charging unit. Also provided is an electrical vehicle charging station (1). The battery charging system can automatically switch a charging operation between battery packs, thereby effectively improving the utilization rate of a charging device, and reducing the investments and operating costs of a charging station. During charging, it is ensured that the charging module of each battery charging unit only establishes a corresponding charging connection and communication connection with one of a plurality of battery packs, so that the safety of device operation is improved. The hierarchical monitoring architecture including a remote monitoring module and a local monitoring module enables a user to use a corresponding monitoring strategy according to actual requirements.
