DEV Update:
Piet presented 2 PRs:
https://github.com/EVerest/everest-core/pull/872
OCPP and API modules need to use external_energy_limits, phase_counts and mapping on evse is needed for that - CURRENT IMPLEMENTATIONS NEED TO BE UPDATED!
https://github.com/EVerest/everest-core/pull/914
Need units for schedules, typically A(mps) for AC and W for DC, for phase switching also in W(att),
PR already merged
Open Mic:
Piet discussed phase switching and reuirements in OCPP 2.0.1 for that (not an issue in 1.6)
AC:max_phase_count would be needed in W limits
→ not present in current energy manager
As Cornelius explained, the curretn energy manager does not track which phase is used, not implemented
also min_Charging_Rate is currentlyx not supported
Recommendation is therefore to not define which phase is used
Piet will continue testing and working on it
Simon: SOme cars have OBCsthat only utilize 2 phases (very rare), would be nice if energy manager knows this
Probably not used in many cars and chargers
Piet: Since nymea is interfacing with EVerest, implementation should be updated accordgin to PR #872
Question from Wei:
How does energy manager and smart charging correlate?
Cornelius: External energy manager always just adds additional limits, so every energy manager can only redistribute and lower the limits - that way internal and external systems can be combined.

Short presentation from Simon S. about nymea, an open source energy manager - Should evaluate if nymea can bring benefits to the EVerest project in one of the next sessions.
