Any difference between 3.6/3.7 kW and 7.2 kW charger sounds like bad/ bad quality (or badly configured) charger in the 3.6/3.7 kW case where charger is actually providing way below 16A than a 7.2 kW charger providing "improvements" over a 3.7 kW one. This could be confirmed if for example the Connected mobile app shows closer to 90% than 100% battery after preconditioning; we already the range displayed in the car is pretty much a random number based on driving history and AC settings... I've charged and preconditioned my 330e in -8 degree celsius (18 F) a few weeks back for several days and battery showed 100% in the mobile app after the preconditioning was ready; this is with an Easee (I've also verified this from the Easee charger's mobile app that shows car drawing maxiumum of 3.7 kW) charger configured to provide 16A. The range car showed inside the car each day was different (between 31 and 37 km); due to my driving history, AC settings etc.. I've also heard that preconditioning can draw maximum of 5 kW, but that just means 5 kW total from cable+battery; it does not indicate higher draw from the Type 2 cable; that would mean car drawing in 22A when no spec says anything about more than 16A; lot of people are using cables/fuses rated to 16A.

I had installed my WallBox from EDF Energy January. They offered OLEV grant plus discount. My installation was not a "standard" one. required a lot of more work and cable, but I still had it at reasonable price all together. They installed 32A extra circuit in my electric board with corresponding charger box.
Hopefully I will collect my car today, so in few days I probably will be able to answer question how much power is draw from box with preconditioning. I know that EDF is not the cheapest one. But they offer me quite good discounts combined with EV tarif. |

I have a 3.7kw capable Pod Point home charger With my car attached to the charger and not on any timed tariff and available to draw power My car this morning was 100% charged with 26 miles forecasted range. After 15 mins pre conditioning the forecasted range had dropped to 19 miles ( all the time attached to the charger) Hope this helps |

If the draw is 5kw for pre conditioning, would the car be able to draw that amount of power from the cable / home charger alone considering the max charge rate is 3.7kwh? |

Again, such a conflict of specs and actual operation would present a (tiny) safety risk if the user assumes 16A max. I've seen 3-pin plugs consistently blow fuse when trying to draw 10A instead of 8A. Speccing 16A max and and actually drawing 22A is not good. |

It is indeed possible the car will draw some from the battery when/if the heater is 5 kW and charger is 3.7 kW. 15 minutes at 5 kW heating would need 0.25h * 1.3 kW = 0,325 kWh from the battery, this is about 3% (about one mile max in range) of the net battery. 1.3 kW above is the diff between what is available from the cable and what the max heating supposedly draws. If one checks from the mobile app the worst case should be car being around 95% battery after max precondtion time (30 mins) at max power. What I am questioning here is claim that a 7,2 kW charger would help. That would mean the car pretty significantly violating its own charging spec. Not saying this is totally impossible, but it would require way better proof than "my predicted mileage tends to look better", for example a power draw readout > 3.7 kW from the charging pod. Lot's of charging stations can display this somehow, my Easee box always displays the charging power at any given moment in the mobile app. |

So as a newbie I am now contemplating getting a home charger for my 330e arrival in Sept. Should I go for a 7KW? At least this will future proof it, even if it doesn't have other beneficial effects?

I would if I were you, as you say future proof it and take advantage of the OLEV while it's there

In my case max is 100km/day, with a high 20kwh/100km consumption that means 20kWh to charge daily. At 3.7kW that’s roughly 5 hours charge. Fine for me while sleeping, so my target charger was 3.7kW. |

My experience with pre-conditioning:
Pre-conditioning with the app With heating on and the car connected to the wall I get 24-26 miles Pre-conditioning with the app With heating off and the car connected to the wall I get 27-29 miles I've found using the preconditioning on the key fob just about when I'm going to leave the house is when I'll loose 3-4 miles of range so 21-23 or 24-26 respectively. |

Its free. Includes chargemaster claiming the grant. Was really easy. I just to pay 85 quid as only 15 metres from the consumer unit included. Its 5 quid per metre extra. You can have tethered or untethered. I went for tethered so don't have to buy an extra cable!
