Received my 6000xp today, quickly hooked it up to a small battery bank to test it, limited charging and discharge amps for small battery and a few other tweaks. Connected load to a L14-30 plug (pulling abolute max 1800w) which then I use a generator cable to plug right into my Reliance Transfer...
Efficiency of EV battery charging primarily depends on the power electronic converter topologies, used in the chargers. Converter topologies presented in [20,21,22] use single-stage AC–DC power conversion for EV battery charging. Two-stage conversion systems use an AC–DC converter followed by an active power factor correction (PFC) and a DC
