johnrhansen said:Here is something I've always wondered. Can the pilot signal indicating the current the EVSE is capable of outputting be a dynamic value? Say for instance, If you have a 100 amp service in your house, and the load on the panel climbs to a value where the panel is near it's capacity while a car is charging at 27 amps... could the EVSE sense the total load on the service panel and reduce it's pilot signal value in real time causing the charger in the car to draw less current to prevent an overload? I built a load shed system for a place I owned once (google "john's load shed") but a system like I just mentioned would be a lot more elegant.
No EVSE that I am aware of uses dynamic current but the specification allows it.
Brad, you can set an OpenEVSE from Chris to exceed its specs. He tries to sell to experienced knowledgeable people that know what they are doing. That is the reason he discontinued the kits. People purchased them and they did not have a clue.
