Hi all, In case it is helpful to others here is a sample output of the V2G metrics populated for the Leaf from a recent session. Note I've opted for presenting the Chademo voltage, current and power output (as the grid voltage and inverter efficiency is not known -external to car- but nominal grid voltage could be set with a parameter and then calculated). v.g.climit 19.8939A v.g.current 7.5A v.g.duration.empty 533Min v.g.duration.range v.g.duration.soc v.g.efficiency v.g.generating yes v.g.kwh 0.0562549kWh v.g.kwh.grid v.g.kwh.grid.total v.g.limit.range v.g.limit.soc v.g.mode standard v.g.pilot yes v.g.power 2.8275kW v.g.state exporting v.g.substate onrequest v.g.temp v.g.time 104Sec v.g.timermode v.g.timerstart v.g.type chademo v.g.voltage 377V Michael, is it possible to have v.g metrics added to the V2 server message format for incorporating into the ovms app? Is it worth having a parameter to indicate car support for V2G functionality? Cheers Derek
Derek, nice work! So the "first" once again goes to the Leaf :-) Of course you can extend the V2 message protocol. Maybe introduce a new message type for that, as "S" and "D" already are quite loaded. The grid log already contains the generator metrics and should be triggered by a change to the gen state metric as well. That's meant to log sessions though, not to transport live data. Car support shouldn't be a parameter (= user config) though, it should be a property of the car adaption. Car capabilities have been on the rework todo list for some time.
