The Session That Never Closes

Advanced

5 min

Technical details off

The driver plugs in and charging begins.

The CPO opens a session and pushes it to the eMSP so the driver's app can show 'Charging'.

Why this matters

The session is the live record of a charge in progress. Both parties now hold the same open session and expect it to be closed the same way it was opened.

As power flows, the CPO PATCHes the session with the energy delivered so far.

The driver unplugs and drives away.

The CPO should now PATCH the session to COMPLETED and follow it with a CDR.
