**Example request B**
This message triggers a schedule starting at 10.00am, at which the state of charge (soc) is 12.1 kWh,
with a target state of charge of 25 kWh at 4.00pm.
The minimum and maximum soc are set to 10 and 25 kWh, respectively.
Roundtrip efficiency for use in scheduling is set to 98%.
