Michael explains the practical split: AC wallboxes fit household power, while DC fast charging belongs to hubs and highways. With AC, the car converts AC to DC via the onboard charger, which sets the speed limit. For home charging, the goal is efficient overnight charging, not maximum power at all times.
Dynamic tariffs expose what the market already knows: prices are low when supply is high and prices spike when supply is tight. Michael’s point is simple: without that signal, most people charge at the worst possible time. With it, a smart setup can shift charging into cheaper hours automatically.
In markets with tighter household capacity, smart charging matters even more. Dynamic load balancing measures the home load and adjusts charging power in real time, so cooking dinner does not trip limits. It is a practical fix that beats manual behavior changes because it works in the background.
Michael frames bidirectional as “vehicle-to-x” where vehicle-to-load and vehicle-to-home are easier wins than vehicle-to-grid. For many cars, the bigger constraint is in the vehicle hardware and the energy management logic. V2G adds billing and incentives and DSO coordination, so it scales later.
"Basically the goal is to have a set it and forget it system, right? Where you just plug in your car every time you come home and it will charge if energy is cheap or if you have your own PV system, there might be some surplus energy coming from that."
"There is so much potential there and the technology is there, it's all finished, it all works, it's proven. Yeah. So let's just use that first."
"I think this is always the most important feature of being sustainable: to make reliable products that have a large lifespan, so as to not produce everything again and again ."
