Wow, the upcoming Ford "Mustang inspired SUV" is going to A) be a massive guzzler, B) be expensive, and C) be super-heavy
Electrify America NEWSROOM
"Ford will be releasing its all-new, Mustang-inspired electric SUV, that aims to achieve a targeted EPA-estimated range of 300 miles. The vehicle’s 150kW charging ability will allow very quick charging speeds on Electrify America’s 150 to 350kW network. Ford estimates that its all-new, all-electric Mustang-inspired SUV will be capable to charge up to 47 miles in 10 minutes using Electrify America DC fast chargers,"
Let's do some math:
- 150000W / (47mi/(1/6 hour) * 6) = 532 Wh/mi
- 300mi * 0,532 kWh/mi = 160kWh usable. Probably 170-180kWh nominal.
- Charge rate: 282mph / 453kph
532Wh/mi? Ford hasn't learned a d*mned thing about the importance of streamlining to making a good EV.
I'm not sure that first equation works as stated? As stated I don't get a sensical much less identical result - 47 / 0.1666... (1/6 being 0.166...) is ~282, then times six is 1692, divided into 150k is 88.65 ... ??
Though I can arrive at the same end results differently... 150kW * 1/6h (10 minutes) = 25kWh, 25kWh / 47 miles = 532Wh/mi.
I was thinking maybe it was supposed to be 47% range not 47 miles in 10 minutes, but then I did the math. 47% of 300 miles in 10 minutes would be improbably good and I have a hard time believing it, as it would come out to 177 Wh/mi. Somehow I doubt Ford managed to build a CUV with 30% less Wh/mi than the Model 3...
I suspect the reality is it can only hit the 150kW for a minute or two and then tapers hard and the charge speed is garbage. If we instead it had bad but not as bad Wh/mi (let's say something around the EQC's 355 Wh/mi) it might have actually a 100~110kW pack, and maybe it averages 100kW charging in that 10 minutes (which means that if it started at 150kW and dropped down to something like 88 kWh - and at < 20% SoC!). I don't even want to think about the taper over a whole 90% charge.
So while I doubt it's efficiency is quite as bad as 532Wh/mi, I also expect it to have really terrible charging rates. Perhaps insufficient pack thermal management to sustain high C rate? So basically no redeeming qualities no matter how you slice it.
