Someone can probably educate me here but from my understanding the 45e has 3,7 Kw as max input from any source (wallbox, fast-charger). This would translate to approx. 6-7 hours from empty to full.
I don't understand the logic in this move from BMW, the are usually in the frontline of tech. The 45e has one of the most powerful batteries among the current generation of phev's. If there was a fairly fast way to charge that would really extend the electrical usability.

The limitation of 3.7 kW maximum external charging power is correct and there's no known way around it. Funny thing is that the high-voltage batteries can accept higher charging currents without problems. If I use Battery Control drive mode to charge the battery with the gas engine, it charges from empty to around 75 % in just one hour in my testing.
The 3.7 kW limitation is my only major disappointment with the car. Using public chargers in shopping malls and other parking places makes no sense because of the extremely low charging power.
