Charging Ahead: The Coming Wave of Non-Tesla Compatibility for Superchargers

So you‘re considering an electric vehicle – excellently eco-conscious! But the single biggest factor still limiting mainstream EV adoption is range anxiety. No one likes being stranded roadside when the battery depletes. Fortunately tremendous strides have been made recently in charging tech and infrastructure that help alleviate these concerns. Specifically – Tesla has committed to opening their robust Supercharger network to other automakers by year‘s end, ushering in an exciting era of charging interoperability.

A Primer on Tesla‘s Market-Leading Infrastructure

Tesla‘s coast-to-coast Supercharger fleet today comprises over 37,000 high-speed connectors spread across nearly 4,000 stations nationwide. Supporting peak charging up to 250kW, the network can replenish ~200 miles in a bleeding-edge 15 minutes. Originally launched in 2012 exclusively for enabling long-distance Model S travel, subsequent expansion has aimed to fully eliminate range anxiety – the top impediment for prospective EV drivers.

And it‘s worked – surveys show that non-Tesla owners regularly flag charging availability as their number one frustration. The combination of proprietary charging design and limited third-party fast charging options creates hassles for road trippers. Hence why anticipation is so high for the pending Supercharger opening…

Cracking Open The Walled Garden: Pilots Pave The Way

The potential has always existed for inter-brand charging cooperation. But historically Tesla has preserved Superchargers as a "walled garden" to exclusively benefit owners and promote vehicle sales. That finally changed in 2021 when a small-scale pilot in the Netherlands opened access via smartphone app and QR authentication. For the first time, non-Teslas successfully charged using the network!

Key technical learnings were around managing demand spikes. During peak hours Tesla restricted station access beyond 50% capacity until congestion eased. Pricing was also notably higher for non-owners – assessed as a premium for the convenience. But the critical infrastructural integration hurdle was officially cleared. When expanded, the pilot demonstrated capacity for enabling smooth roaming across networks.

An Ultimatum From Biden Spurs Plans For Wider Adoption

With strong indications that interoperability was technically feasible, the Biden administration saw an opportunity to spur industry collaboration. In July 2022 at a White House rally celebrating American electric vehicle innovation, Biden conveyed a direct ultimatum to Tesla and other automakers:

“As these companies bring more electric options to market, they all must take steps to ensure that their customers will be able to charge their vehicles conveniently…”

Soon after, Tesla pledged that by year‘s end, Model 3 and Model Y owners would officially gain access to Superchargers across the United States. Other brands like Audi and Rivian also committed to broadening fast charger access. The moves unlock major growth potential for EV adoption, now that convenient, reliable infrastructure is expanding.

What Do The Specs Tell Us About Charging Speed Parity?

Clearly non-Tesla vehicles stand to benefit enormously from access to 12,000+ new Supercharger plugs nationwide. But with different auto designs, what can drivers expect in terms of charging times as networks merge? Let‘s break down the specs:

EV ModelMax Charging PowerMiles Added Per HourBattery Size
Tesla Model 3250 kW1,000 miles75 kWh
Audi e-tron175 kW*700 miles95 kWh
Ford Mustang MachE150 kW600 miles98 kWh
Nissan Leaf100 kW400 miles62 kWh

*with 270kW capability expected by 2023

Tesla still maintains an edge in raw charging velocity. But new models from Porsche, Hyundai, Kia and others show that gap narrowing with each model year. The takeaway is that while network access is essential, vehicle charging hardware also plays a key role in refuel rates.

"Plug & Charge" Tech Removes The Authentication Barrier

In a pleasantly surprising plot twist from August 2022, both GM and Ford announced plans to replace existing cards or apps and instead directly integrate Plug and Charge capability for simplified access. The system identifies the vehicle upon connecting, triggering an automated billing process. No more fussing with QR codes or membership activiations!

On Twitter, GM Executive Mary Barra captured industry enthusiasm at coalescing around Plug and Charge:

The days of juggling logins and RFID cards at public stations will soon be history. As charging networks interlink and streamline, the experience increasingly mirrors the simplicity of pulling up to a gas pump.

Projecting Total Connectors Nationwide As Networks Merge

Analyzing numbers across existing networks paints a picture of the total charger count expected once infrastructure overlaps. Tesla currently operates over 60% of high speed charging hardware in the US. Tallying in the next largest providers, the total connector count reaches over 100,000 plugs:

NetworkCharger Connectors
Tesla Supercharger37,000
Electrify America6,000
EVgo800
ChargePoint67,000
Total110,800

Interoperability therefore stands to triple the functional charging output for non-Tesla drivers without requiring significant new construction. Widespread reciprocity unlocks major capacity already built.

Cost Impacts: Weighing Supercharging Versus Dedicated Stations

Using current pricing models as references, analysis shows comparable costs for non-Teslas whether utilizing shared Superchargers or standalone equivalents. Gas savings generally offset any charging premiums. But convenience and trip flexibility remain the biggest perks:

  • Tesla drivers pay an average $0.24 per kWh at Superchargers, or under $20 per full charge
  • Third party networks bill ~$0.30 on average per kWh, with some as high as $0.40 during peak demand
  • For a 300 mile range EV like a Volkswagen ID.4, annual fuel spending drops from $1,500 (for gasoline) to $650 charging
  • Varying membership plans (like $4 monthly fees) can also trim charging costs further

While pricing for exactly how non-Teslas will be billed at Superchargers is still to-be-finalized, predictions hover around the $0.35 per kWh level. That remains very competitive. And the benefits for enablig longer distance travel easily outweigh slightly elevated charging expenses.

Conclusion: An Ultra-Fast and Connected Future Lies Ahead

Industry insiders project that by 2025 over 25 competitive EV models will offer 300+ mile ranges, 250kW+ charging, with ubiquitous access via Plug-and-Charge. Any lingering notions of electric vehicles being niche or inferior to gas can finally be dismissed!

Hopefully this guide has helped cut through the noise as infrastructure rapildy evolves. The outlook is extremely promising for simplicity, speed, and flexibility regardless what EV you choose. Soon charging will be virtually invisible, opening car travel to everyone. We‘re witnessing simply a passing of the torch as superior ev technology reshapes mobility at large. What thrilling times indeed!
