In the early days of this forum, there was quite a bit discussion about charger efficiency. You may notice in the current mileage thread that I put in details of an incredibly fast DC charge. During that charge, the radiator fan did not come on. When I got home after a 93 mile run, the battery temperature was just about mid scale. Normally, I leave it for an hour to let heat dissipate and normalise but this time I needed the car 90 minutes later so I put it on charge as I got home. Now with 7kW AC charge, the radiator fan came on 30 minutes later. No wonder, as feeling the circulatory piping, the coolant was hot. From this, I deduce that the inverter is the biggest chunk of AC charging inefficiency. Anyone else paid attention to this?
