Sorry for late response... Been out and about driving my wife's Roadster...
Yes, it's an Efacec and runs 152 miles per hour when I first started, then ramped up as high as 156 miles per hour...
That's significantly faster than the Eaton at Mitsubishi or the Nissan in West LA that I've tested.
It might be easier to compare the CHAdeMO speed with amps delivered. One twist to that is that the dash display in the car is showing the net amperage, less overhead for the car. The current maximum is 125 amps for the CHAdeMO standard.
Very, very few will be at 125 amps, and most will be at 120 amps. Virtually all of the Nissan units are 115 amps. Particularly in California, some of these units have been dialed down as low as 48 amps.
Folks tend to equate the CHAdeMO adapter with any failing in speed not realizing, perhaps, that it's the settings in the actual charger that are limiting speed.
Power (kW) is merely amps multiplied by volts. Your particular voltage is based on which car you have, as the cars currently have two maximum voltages; 352v for 60/70 cars (84 cells in series) and 403v for 85 and probably 90 cars (96 cells in series).
Therefore, pulling 115-125 amps from a CHAdeMO charger with a higher voltage battery will show more "MPH" and kW than one with a lower voltage. My point is that to accurately compare CHAdeMO performance to each unit, amps is key, not MPH or kW.
I plugged my car into a Nissan CHAdeMO unit operated by NRG / eVgo in Los Angeles recently. Not surprisingly, it performed exactly as I expected, delivering the rated amps, and displaying the rated amps less the vehicle's overhead of several amps on the dash.
Typical performance of my 70D on a Supercharger(max rated miles 240):
Min - Rated Miles - Volts - Amps - kW - MPH Calculated@ 287 Wh/mile
0 ------- 7 --------- 282 --- 0 ------- 0 ------------- 0 ----
1 ------- 9 --------- 310 -- 367 -- 113.7kW ------ 396mph
2 ------ 21 --------- 316 -- 360 -- 113.7kW ------ 396mph
7 ------ 49 --------- 322 -- 335 -- 108.8kW ------ 379mph
10 ----- 65 --------- 324 -- 305 -- 98.8kW ------- 344mph
15 ----- 92 --------- 327 -- 254 -- 83.0kW ------- 289mph
20 ---- 113 --------- 331 -- 216 -- 71.5kW ------- 249mph
With any CHAdeMO adapter, the charger will merely chug along at whatever setting that the charger is set at in amps until perhaps 80% (200 miles for my car). This assumes, of course, that the adapter doesn't overheat and slow down (already has happened), or the charger overheat and shutdown (common with Nissan chargers), or the battery temperature is too hot or cold, et al. What follows is a dramatization of a 115 amp Nissan charger with my car. Remember, 115 amps will show as 111-112-ish on the dash:
Min - Rated Miles - Volts - Amps - kW - MPH Calculated@ 287 Wh/mile
0 ------- 7 --------- 282 --- 0 ------- 0 ------------- 0 ----
1 ------- 9 --------- 300 -- 111 -- 33.3kW ------- 116mph (about two miles per minute)
4 ------ 17 --------- 306 -- 112 -- 33.5kW ------ 118mph
16 ----- 49 --------- 312 -- 111 -- 33.8kW ------ 120mph
25 ----- 65 --------- 316 -- 112 -- 34.6kW ------- 122mph
40 ----- 92 --------- 320 -- 111 -- 35.0kW ------- 124mph
55 ---- 113 --------- 324 -- 111 -- 36.0kW ------- 125mph
75 ---- 153 --------- 333 -- 112 -- 36.5kW ------- 127mph
90 ---- 183 ----------343 -- 111 -- 37.3kW ------- 130mph
105 --- 210 --------- 352 -- 108 -- 38.0kW ------- 133mph (first amp limiting due to max volts)
120 --- 228 --------- 352 --- 60 -- 21.1kW -------- 73mph
140 --- 240 --------- 352 --- 0 -------0kW --------- 0mph
Hopefully, it's easy to see how an 85-90kWh Tesla with 403v battery during charging wiill gain significantly more rated miles and higher kW with CHAdeMO:
111a * 385v = 43kW typical
