There is an issue with the previous condition. For example, in a charging station with two connectors, if Connector 0 is already in a "Reserved" state and the user first inserts the gun into Connector 1, Connector 1 will transition to a "Preparing" state, and the available_count will be equal to 1. As a result, the condition of available_count > 1 cannot pass the validation, leading to a failed charging initiation.
