Hey Rajesh,
The solenoid should disengage once you have put the key in and turned it on. It does not depend on the power coming in from the pod or not.
Hence, power or no power, the solenoid will disengage if the key is turned on. In this instance it might have been due to the charging handle and the port having some friction. I will request the customer service team to give you a call and understand this better.
Regards,
Shreyas
