How does Reduxi handle multiple EV Chargers?

First, we share a little knowledge from Primož.

"6 A is the standard minimum current for EV chargers, but some cars will not charge at the 6 A setpoint."

One possible explanation is that there is always some current drop when charging. Some cars will always charge 0-25% lower than the EV limit. At the 6 A limit, this can be 4.5 A and cause the vehicle to be unable to start charging. Under our observation, 9 A is the preferred minimum setpoint for EV chargers.

Reduxi offer current overshoot when starting offline EV chargers.

Suppose we allow short current/power draw over the limit when starting new devices. In that case, Reduxi will start a new charger over the current limit if there is enough flexibility in fine-tuning the setpoint for running EV chargers without turning them off. When overshoot over the current limit is expected, the strategy will try to start one EV charger at a time by cycling the setpoint.

Equalizing power between EV chargers

For more information about this strategy, please read our technical document on Dynamic strategy for EV Chargers. You will find it under Reduxi Controller tab, Configurator -> Dynamic strategy for EV Chargers.
