Ford CEO Jim Farley and Tesla boss Elon Musk participated in a joint announcement Thursday evening that Ford EVs will quickly have entry to Tesla’s Supercharger high-speed charging community.
Neglected within the welcome information that Ford drivers will be capable of use Tesla’s bigger and extra dependable charging community is the truth that Ford dedicated to switching its EVs from immediately’s Society of Automotive Engineers (SAE) Mixed Charging System (CCS) customary charging plug to Tesla’s North American Charging System (NACS) plug. “We’re completely dedicated to the NACS interface itself going ahead,” Farley acknowledged.
It will imply that non-Tesla EV homeowners could possibly be plunged right into a complicated requirements battle between teams, harking back to the Sony Betamax versus VHS videotape battle of the Nineteen Eighties. The stakes are increased right here, contemplating the a lot increased value of EVs versus VCRs and the prospect of being stranded at an incompatible charger with an EV compared to the prospect of being at a video rental retailer with the incorrect format of tapes for the night’s leisure.
CCS vs. NACS
The SAE reiterated its level that its J1772 customary with the piggybacked DC fast-charging CCS connector is the {industry} customary in a press release in October. “The interoperability that SAE J1772 offers is important as THE customary to serve the collective {industry} and basic public,” mentioned Raman Venkatesh, then-chief working officer of SAE Worldwide. “This customary was developed in partnership throughout {industry} in an effort to keep away from confusion over proprietary options.”
“SAE Worldwide is the acknowledged authority on car engineering requirements, together with the consensus-based growth of SAE J1772 AC/DC combo coupler charging customary – stabilizing and unifying the worldwide marketplace for EV/PHEV producers and paving the best way for future international electromobility,” the discharge emphasised. “SAEI partnered with 190 committee members representing all of main international EV-producing corporations on the event of this charging customary.”

This was issued maybe in anticipation of Tesla’s November announcement that it was making its NACS charging specification open to all producers. “We invite charging community operators and car producers to place the Tesla charging connector and cost port, now referred to as the North American Charging Customary (NACS), on their gear and automobiles,” Tesla mentioned in an unsigned weblog put up.
Whereas SAE’s customary was developed with industry-wide participation and has displaced alternate options like Japan’s ChaDeMo charging customary that Nissan just lately dropped on its Leaf EV in favor of the CCS charger. There are nonetheless ChaDeMo public charging stations which are offering much less profit for EV drivers by the day, because the non-ChaDeMo EV pool grows. This could possibly be the way forward for the present CCS public DC quick chargers on networks like Electrify America, ChargePoint, and Blink, in addition to for J1772 Stage 2 AC house chargers if different carmakers comply with Ford’s instance and change allegiance to Tesla’s NACS design.
Why Change?
There are good causes for them to take action. The non-Tesla public charging community has earned a popularity for disappointing efficiency and reliability. In keeping with J.D. Energy’s U.S. Electrical Car Expertise (EVX) Public Charging Research for the primary quarter of 2023 exhibits that whereas public charging station reliability has improved for the primary time in two years, buyer satisfaction continues to be dismal. Via the tip of March 2023, 20.8 % of EV drivers utilizing public charging stations skilled charging failures or gear malfunctions that left them unable to cost their automobiles, J.D. Energy studies.
The NACS charging port handles each Stage 1 and a couple of AC charging in addition to the Supercharger community’s DC quick charging. The SAE J1772 connector for Stage 2 AC charging can’t settle for DC quick charging, so the CCS, as its identify suggests, is a mixed plug that provides two extra ports to the prevailing J1772 connector that gives the DC connection. The result’s a big, cumbersome connector. Tesla’s Superchargers have slim connector handles with smaller-gauge cables which are simpler to handle.
Whereas CCS public chargers like Electrify America’s stations declare a peak charging capability of 350 kilowatts for 800-volt EVs such because the Lucid Air, my expertise has been that they don’t obtain this lofty stage in real-world charging. Tesla’s speediest model 3 Superchargers are rated at a decrease 250 kW, but when they’ll reliably present this full quantity persistently, that may be higher than the underperforming 350 kW chargers on different networks.
Moreover, Tesla has extra charger areas than the non-Tesla networks. “NACS automobiles outnumber CCS two-to-one, and Tesla’s Supercharging community has 60 % extra NACS posts than all of the CCS-equipped networks mixed,” Tesla noticed in its November weblog put up. Previewing the Ford announcement, it additionally mentioned “We sit up for future electrical automobiles incorporating the NACS design and charging at Tesla’s North American Supercharging and Vacation spot Charging networks.”
Extra Change is Coming
One other tidbit in that put up is the announcement that different charging networks will shift to supporting NACS connectors. “Community operators have already got plans in movement to include NACS at their chargers, so Tesla homeowners can sit up for charging at different networks with out adapters,” it mentioned. None of these different charging networks have but responded to requests for remark, however I’ll comply with up once they do. It will in all probability not be till they’re ready to formally announce their corporations’ new insurance policies with regard to charging requirements.
Future public charging networks could possibly be outfitted with two connectors to deal with each CCS and NACS.
At this time, Tesla sells its clients adapters to let their automobiles plug in to J1772 Stage 2 charging stations for $50 and offers one with every new automobile. For Ford clients to hook up with Superchargers, Tesla is creating a unique adapter, in line with Musk. “I believe we’re aiming for that adapter to be in manufacturing early subsequent yr,” he mentioned in the course of the Twitter Areas stay stream of the announcement. “Within the lots of of {dollars},” he added. “It’s an adapter, so it isn’t tremendous costly.”
Tesla’s intention is to transform the {industry} to its customary, Musk mentioned. “If, working with Ford and maybe others, we will make it the North American customary, I believe shoppers can be all the higher for it.”
“It’s not nice for the CCS customary,” noticed Mike Austin, senior analysis analyst for electrical automobiles at Guidehouse Insights. “Ford’s transfer is a recognition that many of the EVs on the street immediately use NACS. Sure, everybody might want to carry not less than one adapter for a very long time (very like how Tesla homeowners want SAE port adapters).”
One functionality that CCS has that NACS doesn’t presently present is bi-directionality,” Austin factors out. “There are nonetheless a number of unanswered questions as properly, like how Ford will deal with bidirectional charging, which it already has on the F-150 Lightning, utilizing the Tesla port.” That is the supply of the Ford F-150 Lightning’s capacity to supply energy to run a house throughout an influence outage or the Kia EV to cost one other EV that’s low on juice.
This can be a priority for Ford patrons as soon as the corporate switches over to the NACS connector beginning in 2025. That leaves loads of time for bi-directionality to be added to NACS, however at this level, there is no such thing as a info on that plan. “We’re not speaking about that but,” mentioned Ford PR particular person Lori Arpin.
The sight of a Ford Mach-E at a Tesla Supercharger station could turn out to be widespread beginning subsequent yr.
Good for Ford, However What About Tesla?
Regardless, this marks a win for Ford EV homeowners and potential patrons. “Total, it is a stable transfer for Ford, as a result of it basically removes the principle challenge of public quick charging for potential patrons,” Austin mentioned. “There are way more Superchargers than every other community, they usually’re usually extra dependable.”
Ford says that its clients may have entry to 12,000 Superchargers, which is about half of the chargers on that community. Presumably this restrict is to placate Tesla drivers who can be sad to attend for a cost whereas a Ford is on the charging station forward of them. “My assumption is that will probably be half of the ports, not half of the stations, leaving some exclusivity to Tesla clients,” Austin mentioned. Tesla is offering entry to its utility programming interface for the Supercharger community, so drivers utilizing Ford’s apps will be capable of inform which chargers are open to them utilizing their app, he identified.
Ford’s Farley mentioned he had an epiphany concerning the inadequacy of the charging networks accessible to Ford drivers throughout a trip. “It turned clear to me, I used to be on trip with my household final yr in Lake Tahoe, I used to be driving again to Monterey and my children saved me and going, ‘Hey dad, there’s one other Supercharger, can we cease there? How about there? How about on the I-5?’ I used to be like, ‘No, now we have to go over right here, behind this different constructing.’ It sort of turned apparent to me what a job [Tesla’s] crew had executed and what it means for purchasers.”
Farley is unquestionably right on this statement, however the important {industry} disruption that may consequence if carmakers start switching over to a unique customary than the one that’s presently already deployed with current EV drivers with compatibility complications in the course of the transition.
