These are absolutely key to our energy management algorithms, and would be very useful if you want to match a load profile or generation profile (like solar ) - again the challenge you have is that the charger may not respond to these messages (depending on what power/energy mgt capacities .
Let me know your use case , I can give some suggestions however it will come down to the charger capability
