Which lockscreen security setting are you using?
By default, any setting other than Swipe disables the USB connection when the screen is locked for obvious security reasons.
You can try enabling 'Stay Awake' under developer options, this keeps the screen on whilst "charging". Or if security isn't an issue, use the Swipe to unlock security mode.

Never underestimate the power of stupid people in large groups.
The simplest solutions are often the cleverest. They are also usually wrong.
