Hi Kezo,
great posts. Unlike you, I’m not an electrical engineer. My dad was, but all I learned from him was to employ a professional! In addition and not often discussed, conversion from AC to DC and vice versa are not a free lunch as are the losses in transmission lines from the windmill at sea to the domestic grid near you. Talk of large scale battery storage – DC- such as employed in South Australia and Queensland, is wishful thinking in the uk on cost, size and resource shortfalls. A new facility in Australia suffered a catastrophic thermal runaway, fire, explosion and clouds of highly toxic smoke. EVs inverter efficiency has been improved, as featured in the new VAG updates, but surely the V2g rectifier would not cope with household loads? According to experts who were discussing the quote for a EV battery replacement -$45000, ouch,-charging above 80% and repeated fast charging were detrimental to battery longevity and charge capacity deterioration, just as they are in an iPhone. This extra cycling if using V2g will surely result in increases to the current, environmentally disasterous, “ early retirement” of resource hungry EVs due to battery damage or deterioration.
Roll on solid state batteries. Are the new BYD sodium high density batteries an improvement?
