Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

New Jersey votes to allow direct Tesla sales

It's not quite the law that Tesla Motors can sell its car directly to customers in New Jersey, but the state has taken one step closer to that reality. Yesterday, New Jersey's Assembly Consumer Affairs Committee voted 4-0 to approve bill A3216, which would "Permits certain zero emission vehicle manufacturers to directly sell motor vehicles to consumers and requires them to operate service facilities." The EV automaker's ongoing dealer fight took a turn for the worse in New Jersey a few months ago, when the state legislature voted in mid-March to prevent Tesla stores from conducting their business. Tesla had been selling cars in the sate, but Governor Chris Christie said the ban was just an enforcement of a law that had been on the books for years, something Tesla said was an "affront to the very concept of a free market." If A3216 becomes law, then electric vehicle makers would be able to operate "no more than four places of business in the State" as well as one service center. The bill will let Tesla "conduct the business of educating the public about electric vehicles" – Diarmuid O'Connell Speaking to the committee, Tesla's vice president of business development, Diarmuid O'Connell, said, "This is a super important issue for us in New Jersey, and as some of you would know, nationally as well. ... [The bill would] allow us to in a modest way and a reasonable way conduct the business of educating the public about electric vehicles and getting as many of those vehicles on the road as quickly as possible." Speaking for the New Jersey Coalition of Automotive Retailers, president Jim Appleton said that this solution is fine for start-up EV automakers, but that the franchise model should still be the goal for anyone selling cars. This fight isn't nationwide yet, but the FTC has come out against what it called "protectionist" anti-direct sales mandates, so we expect to be hearing more as time goes by.

Volvo to adopt NACS port, partners with Tesla for Supercharger access

Volvo is the next automaker to announce that it’s signed an agreement with Tesla with will allow its current and future electric vehicles use of the Supercharger network. Plus, just like Ford and GM, Volvo says its new EVs from 2025 on will be equipped with the North American Charging Standard (NACS) port instead of the Combined Charging System (CCS) port. This agreement makes Volvo the first European automaker to adopt TeslaÂ’s charge port and gain access to the 12,000-plus Superchargers across the U.S. Volvo says that owners of its EVs will be able to access Superchargers as early as the first half of 2024 with an adapter. For Volvo EVs built with the NACS port, Volvo says those vehicles will still be capable of charging on CCS chargers with an adapter provided by Volvo. Volvo didnÂ’t explicitly say that the Supercharger network would be integrated into its carsÂ’ native navigation system (which is just Google Maps these days), but it did say that folks will be able to use the Volvo Cars app to do so. Via the app, youÂ’ll be able to locate chargers, get real-time availability info and pay for charging sessions. “As part of our journey to becoming fully electric by 2030, we want to make life with an electric car as easy as possible,” said Jim Rowan, Volvo CEO. “One major inhibitor to more people making the shift to electric driving – a key step in making transportation more sustainable – is access to easy and convenient charging infrastructure. Today, with this agreement, weÂ’re taking a major step to remove this threshold for Volvo drivers in the United States, Canada and Mexico.” Stay tuned, as itÂ’s only a matter of time until more and more automakers make a similar decision as Ford, GM and Volvo just made.
