Tesla is offering its proprietary charge connector as a new North American standard
Tesla is making moves to dominate the EV charging space, announcing today that other car brands can now build vehicles with its proprietary charging port design.
This refers to the prong design at the end of the charger, as well as the plug the prongs feed into on the car. The charger’s prongs must match the car’s port—just like a lamp plugs into a wall outlet, for example—to successfully deliver power.
“We invite charging network operators and vehicle manufacturers to put the Tesla proprietary charge connector and charge port, now called the North American Charging Standard (NACS), on their equipment and vehicles,” Tesla says in a blog post(Opens in a new window), which includes a specifications sheet for download. “We are actively working with relevant standards bodies to codify Tesla’s charging connector as a public standard.”
There are a few types of charging plugs out there, though Combined Charging System (CCS) connectors have effectively become the national standard. Most, if not all, automakers besides Tesla use it on their vehicles.
President Biden even specified that a new national charging network must be built with CCS connectors. This type of standardization is key to universal access to public infrastructure, just like all gas-powered cars can fuel up at any station. You don’t have to look at a map to figure out which gas station works with your car, as you do now for EV charging stations.
Tesla argues that its NACS design is superior to the CCS and that it’s the real national standard since Tesla has the highest share of the EV market and the largest charging network (for now).
“NACS vehicles outnumber CCS two-to-one, and Tesla’s Supercharging network has 60% more NACS posts than all the CCS-equipped networks combined,” says Tesla. “It has no moving parts, is half the size, and is twice as powerful as Combined Charging System (CCS) connectors.”
The company is also supposed to open its Supercharger network to non-Tesla EVs, but the last we heard about that was in July when the White House said Tesla would “begin production of new Supercharger equipment that will enable non-Tesla EV drivers in North America to use Tesla Superchargers…later this year.” Until then, that capability is only available in Europe(Opens in a new window).
As stated in the release published on their official blog, Tesla gave their rationale behind this change. They wrote, “In pursuit of our mission to accelerate the world’s transition to sustainable energy, today we are opening our EV connector design to the world. We invite charging network operators and vehicle manufacturers to put the Tesla charging connector and charge port, now called the North American Charging Standard (NACS), on their equipment and vehicles.”
The design files of the charging connector were also published for download as a part of this announcement. From the numbers published in the release, it was stated that the number of charging stations fitted with NACS is much higher than the ones with CCS (Combined Charging System). The company also published images comparing the two chargers, illustrating the differences between what the chargers look like now, and what could they potentially look like if things go ahead!
As The Verge points out(Opens in a new window), the infrastructure bill that has allocated funds for the US charging network requires that companies build charging stations that support more than one type of EV to get any of that cash. So right now, Tesla doesn’t qualify.
This move could potentially put an end to the disparity between different charging connectors being fitted into the EVs being offered by several brands in the region. Additionally, if and when, Tesla moves to markets like India, this move could be seen as a great precedent by the auto manufacturers as we look to cut down on emissions and waste as a whole.
