Lower than two years in the past, Tesla introduced in November 2022 that they’d be opening their charging protocol to all automakers. They hoped to show their previously proprietary normal, now dubbed the North American Charging Commonplace (NACS), into the default quick charging answer for electrical automobiles in North America.
Whereas automakers and customers initially didn’t appear , we started to see cracks kind within the CCS alliance. In early 2023, Ford introduced it will be departing and siding with Group NACS. By the tip of the yr, most main automakers had deserted the CCS protocol and adopted the NACS normal.
DC Quick Charging Adapters
InsideEV’s personal Tom Moloughney has now examined NACS to CCS1 adapters from Tesla, Lectron and A2Z. Whereas all carry out very nicely in checks, the Lectron is the simplest to function because of a extra pure technique for detaching the adapter. However solely the Tesla adapter is at present accepted to be used at Tesla’s Supercharging stations.
Now, Tesla has began a gradual rollout of approving new manufacturers to be used with the Supercharging community. Sooner or later, automakers like GM, Ford and Hyundai will ship with NACS ports as normal. However for present house owners, use of the Supercharging community would require a CCS to NACS adapter.
Now we have already seen these adaptors in motion after Ford started transport their adapter lower than a month in the past. State of Cost’s Tom Moloughney bought an earlier have a look at a pre-manufacturing mannequin a number of weeks in the past. Now Tom has gotten his palms on the ultimate manufacturing model and he’s right here to supply us with a full evaluate.
At first look the models seem equivalent, proper all the way down to the patented Tesla panel gaps. Whereas we don’t have a teardown of the unit but, Tom predicts that the precise electronics are encased in a second casing under the outside shell.
As soon as the adapter is on the market on the market, it’s anticipated to price $230 and it helps a max of 1,000v and 500 amps. The adapter is at present not UL 2252 licensed for the reason that certification just isn’t finalized but. However like his beforehand reviewed Lectron and A2Z merchandise, the official Tesla-made product is designed to adjust to the upcoming UL 2252 specs.
Testing was carried out on the similar Allamuchy, NJ Supercharger because the Lectron and A2Z adapters. The identical charging stall was additionally used. As earlier than, he charged an F-150 Lightning from 10% to 80%, measuring the temperature of the adapter each 5 minutes.
To connect the adapter to the Supercharging cable, you merely want to slip it onto the NACS plug. The adapter locks into place mechanically.
Eradicating the adapter is not fairly as seamless. There’s a sliding tab on the decrease half of the adapter beneath the NACS plug. Each the adapter and cable should be straddled awkwardly to launch the lock. Tom prefers the ergonomics of the Lectron adapter which has a extra pure set off launch.
Take into account that neither the Lectron or A2Z adapters are formally accepted to be used with the Tesla Supercharging community. Tom expects that after all of those merchandise are UL 2252 licensed, they are going to most certainly be accepted to be used on the Supercharging community. However till they’re formally accepted, use different adapters at your individual threat. If some fault happens and causes injury, you can be held liable.
Tom discovered that the utmost pull for all three adapters was a good 161 kW. That is just a few kW decrease than the utmost draw from an EVgo or Electrify America station. Beginning at 10% and going as much as 80%, the cost session added 90 kWh in 45 minutes.
Initially of the session, the adapter measured 52.5 levels on a cool, breezy day with an exterior temperature of 55 levels. The temperature peaked at 88 levels 25 minutes into the cost session.
Total, the official NACS to CCS adapter carried out very equally to the Lectron and A2Z adapters. The one actual unfavorable is the method of detaching the adapter. After common use, EV house owners will turn into accustomed to this ritual and it’ll really feel extra pure. However the unlocking of the Lectron adapter is far more instantly intuitive.
The compact design is sweet, as is the sturdy metallic tab for locking to your automobile. The adapter additionally appears to direct warmth away from the perimeters of the unit the place you grip it most incessantly.
The one actual draw back for house owners of different EVs? Whereas these adapters will probably be transport out to Ford and Rivian prospects over the approaching weeks, it is going to be fairly some time earlier than they’re broadly accessible to different EV drivers for buy.
Have you ever obtained one of many NACS to CCS adapters to your EV but? If that’s the case, what has been your expertise with the Supercharging community up to now? Tell us within the feedback under.
