How do I charge the battery of the BMS-5S board?

Hello,I lookated at the schematic of the BMS-5s and found that there is no charging interface, how to charge this?

Not sure if I understand your question. The part of the schematic in the picture does not have to do with charging. It’s only for the internal power supply of the bq76920.

Which program is that by the way? It doesn’t look like the KiCad schematic…

Did you see that there is a second power PCB for MOSFETs etc.? Maybe that answers your question.

Yes, I’m using DxDesigner. The VBAT plus on another board doesn’t use it, how does this charge?

The battery is charged via the LOAD+ connector.
