These charging power settings allow one to protect the charging circuit in situations in which the EVSE can't be configured to protect the charging circuit.LCTRNZ said:Can anyone explain to me when using the level 1 charger at home (my level 2 will be ordered soon), must I select Maximum or Reduced or Low charge setting? Also, how do I know to select Reduced or Maximum when using public Level 2 chargers?
For a portable EVSE like the Level 1 EVSE included with an i3 that cannot be configured to limit its charging power, the car must limit the charging power if the charging circuit cannot safely deliver the 10A or 12A that the EVSE can require, depending on which i3 EVSE one has. If this EVSE is plugged into a 15A or 20A circuit with no other electrical loads on this circuit, then the Level 1 charging power can be set to "Maximum". However, if the circuit has other electrical loads and using the EVSE with the car's charging power set to "Maximum" results in the circuit's circuit breaker tripping or fuse blowing, then the Level 1 charging power should be set to "Reduced" or even "Low" if "Reduced" still results in a tripped circuit breaker or blown fuse. If one charges at different locations, the Level 1 charging power setting might need to be changed which can be easy to forget to do.
I am not aware of a Level 2 EVSE that cannot be configured to limit its charging power, so setting the Level 2 charging power to "Maximum" is the normal setting. The "Reduced" setting is available in those rare situations in which the Level 2 EVSE is not able to protect its charging circuit.
