Expense settled accounts.The related data generated during current transformation can be shown on human-computer interaction interface.
Step S206 if verifying active user is not involved in current transformation, is generated and output scheduling is unsuccessfully alerted letter
Breath.
The flow that scheduling system according to embodiments of the present invention participates in current transformation between electric car and power grid includes：Work as scheduling
When system requirements electric car participates in current transformation (V2G technologies), traffic order is communicated to charger.Charger first confirms that this
Whether electric car is agreed to participate in V2G technologies.If agreeing to, the battery status of current electric car is confirmed by monitoring module, if prison
Control module thinks that the battery status of the electric car is good, then starts V2G scheduling；Otherwise, reporting scheduling system, scheduling failure.When
After starting V2G scheduling, battery of electric vehicle is discharged by the reversible transducer of charger to grid side, and passes through bidirectional measuring electricity
The expense of meter amount current feedback power grid electric energy.In entire charging process, protection module ensures that charger state is normal, monitoring
Whether there is a situation where overdischarge for module monitors battery.Meanwhile communication module gives charge and discharge process real-time report to scheduling system,
And notify user.By the above process, it can realize charger and dispatch the real-time communication between system and user, and according to
Battery of electric vehicle energy back to power grid and is dispatched system by the requirement of V2G technologies, while can measure the electric current during this
Converted quantity and the corresponding expense generated.
