Vehicle To Grid (V2G) Technology Achieves Milestone Toward Commercialization

Vehicle to Grid (V2G) technology offers what might be characterized as the holy grail for electric vehicles, and the future got a lot closer on March 12 with the news that a bidirectional EV charging system by Fermata Energy was the first such system in the world to earn the UL 9741 safety standard. UL 9741 features the ability to prevent the discharge of energy when a connected device is not capable of safely receiving backfed power and is a critical milestone toward commercial deployment of V2G.

According to Francisco Martinez, business development director of UL’s Energy Systems and eMobility division, “UL’s role in making the most of the stored energy in electric vehicles is to help ensure that this happens safely,” said Martinez.

The ability of electric vehicles to discharge energy holds great potential because the vehicles tend to have large batteries with more energy than drivers typically need on any given day; moreover, as with most noncommercial passenger vehicles, EVs are are parked an average of 95% of the hours in a year. The combination of having excess energy and being available a large percentage of time results in benefits that will accrue to:

  • The grid, which can use energy from EV batteries to displace higher cost and potentially dirtier energy from power plants when demand for energy is high; and
  • EV owners, who can monetize the energy as it is dispensed (assuming the energy was purchased and stored at a lower cost).

All indications are that V2G is going to introduce significant new resources to the grid. According to comments this week in Berlin by Volkswagen’s chief strategist Michael Jost:

By 2025 [Volkswagen] will have 350 gigawatt hours worth of energy storage at our disposal through our electric car fleet. Between 2025 and 2030 this will grow to 1 terawatt hours worth of storage. That’s more energy than is currently generated by all the hydroelectric power stations in the world. We can guarantee that energy will be used and stored and this will be a new area of business.

Even today’s relatively small number of EVs is providing hundreds of millions of dollars in net revenue to utilities, according to a recent report by Synapse Energy Economics and as illustrated in the following table from the Synapse report:

Table showing net benefits EVs deliver through V2G technology
Total costs and contributions of incremental EV load, 2019-2030.

As vehicles begin to not only consume energy (providing revenues to the system) but also provide value by sending energy back to the grid, the financial and environmental benefits to EV owners, utilities, and all other utility customers will multiply.

“By unlocking the full potential of electric vehicles, Fermata Energy is helping to accelerate the shift to more electric vehicle usage,” said David Slutzky, CEO and founder of Fermata Energy. “We believe bidirectional energy solutions such as Fermata Energy’s V2G system will play an important role in reducing energy costs, improving grid resilience and combating climate change. We’re excited to be the first company to receive UL 9741 certification and look forward to partnering with other organizations to advance V2G applications.”

EV Charging Network ChargeLab Bets Future on Open Standards and Interoperability

Electric vehicle charging network provider ChargeLab announced this week that eligible multi-family communities and office buildings in Canada can receive EV charger installations for $0 in upfront costs.

Canada’s new Zero Emission Vehicle Infrastructure Program (ZEVIP) program (funded by Natural Resources Canada (NRCan)) offers 50% of the total project cost, up to a maximum of $5 million. And for a limited time, ChargeLab is matching NRCan’s contribution for eligible projects, bringing the upfront deployment cost for buildings to $0. These investments are subject to repayment over time based on pay-per-use fees generated by the EV chargers installed.

Innovative financing models like this signal the expectation that while limited co-investment by the public sector may be required in the short run, over the long run EV charging will be a successful commercial venture. As described in the video below by ChargeLab CEO Zachary Lefevre, one of the company’s distinguishing features is its support of interoperability and open standards such as Open Charge Point Protocol (OCPP). OCPP avoids vendor-lock by allowing station owners to switch networks by simply downloading new software over the air.

In the absence of open and interoperable hardware and networks, station owners such as apartment and office building landlords may incur steep costs, including potentially replacement of the entire charger, just to switch networks. The position taken by ChargeLab, which is that customers should be able to have options about which network to run on a charger, and which is consistent with that of other networks including Greenlots and Driivz, is highly favorable to customers and will serve the industry well.

EV Incentives Introduced In Vermont

Picture of Vermont State House in Montpelier, Vermont.

The State of Vermont today launched an incentive program for the purchase or lease of new plug-in electric vehicles, which includes all-electric vehicles and plug-in hybrid electric vehicles. Vermont is far behind its goal of more than 50,000 plug-in vehicles by 2025.

More than 20 plug-in models are eligible for the program, with $1500 incentives for plug-in hybrid vehicles and $2500 incentives for fully electric vehicles. Larger incentives are available for individuals whose households qualify for Vermont’s Weatherization Program. (All incentives in this program are limited to individuals with an annual household income of $92,000 or less applying for a new PEV with a base price of $40,000 or less).

The new state incentive will be in addition to rebates proposed by Green Mountain Power (currently under review by the Vermont Public Utility Commission), which would equal $1000 for plug-in hybrids, $1500 for new fully electric vehicles, and $750 for pre-owned EVs, each of which will be supplemented by a free networked EV charger valued at $600.

Although the total cost of owning (i.e., purchasing and operating) an EV is already below that of an internal combustion-powered vehicle, higher up-front costs remain a barrier for some. These incentives will reduce that cost and are expected to result in increased vehicle sales.

Report Finds Electric Trucks and Buses Both Economical and Critical to Reducing Greenhouse Gases

From garbage trucks to transit buses to “big rigs,” heavy-duty vehicles powered by diesel are a major source of air pollution. Emissions from these vehicles have been linked to adverse health impacts and are a significant contributor to global warming.

But a new report finds that trucks and buses powered by electricity can deliver a litany of benefits, including mitigating climate change. The report, by Earthjustice, the Natural Resources Defense Council (NRDC), the Union of Concerned Scientists, and the California Electric Transportation Coalition, concludes that electric trucks and buses:

  1. Can deliver the largest reductions in greenhouse gas (GHG) and nitrogen oxide (NOx) pollution (transportation accounts for 50 percent of all GHG emissions and 80-90 percent of smog forming pollutants when fuel production emissions are included);
  2. Will be cost competitive by 2030; and
  3. Will create the greatest economic benefits when compared to other emission reduction strategies for heavy-duty trucks and buses.

Improving Air Quality

Electrifying the heavy duty vehicle market can have a huge impact on air quality. According to a report by the Union of Concerned Scientists, despite comprising just 10 percent of vehicles on American roads, heavy-duty vehicles contribute 28 percent of global warming emissions from the nation’s on-road transportation sector. They are also responsible for 45 percent of on-road NOx emissions (oxides of nitrogen) and 57 percent of on-road, direct PM2.5 emissions (particulate matter less than 2.5 micro-meters in diameter). And on-road sources of air pollution disproportionately burden communities of color and low-income communities due to their proximity to roads and vehicular traffic. Asian Americans, African Americans, and Latinos are exposed to 34 percent, 24 percent, and 23 percent more PM2.5 pollution (respectively) from cars, trucks, and buses than the national average.

A Cost Effective Solution

On the subject of cost, the report finds that by 2030 the lifetime cost of EV ownership is expected to be lower than diesel even without purchase subsidies. Until then, subsidies may be required to be cost competitive with diesel. According to research from the California Air Resources Board and others, in nearly every vehicle case examined, including long-haul semi trucks, battery-electric trucks and buses are cheaper than diesel vehicles on a total-cost-of-ownership basis for vehicles purchased within the next 10 years.

In the meantime, according to Jimmy O’Dea of the Union of Concerned Scientists, “significant investments must be made in electric vehicles and infrastructure now to support the transition to zero emission trucks and buses.”

Ron Grosinger and one of his students, Isamara Lozano, pose in front of electric-powered 1990 Volkswagen Cabriolet.

As technology and STEM-focused curricula become ever more important, high school automotive shop classes have been suffering dwindling interest from teachers and students alike. Enter Ronald Grosinger, of Memorial High School in New Jersey, who figured out how to reposition the vocationally oriented course to appeal to a broader audience and prepare students for a wide range of career paths. “If you’re teaching students about gasoline cars, that’s basically the equivalent of 8-track players,” says Grosinger.

Grosinger persuaded his school to purchase a 1990 Volkswagen Cabriolet so that his class could remove the internal combustion engine, install batteries, and rebuild the vehicle to be powered by electricity.

Over time, the students learned how to produce the various mechanical parts in cardboard, then wood, then steel. They welded parts, tackled wiring and learned to solve problems as they arose. Within a year, the student makeup of the class had expanded to include advanced math, science, physics and engineering students. Also, there were many more female students.

The curriculum has evolved over the past ten years, and now is structured around what Grosinger calls the Four Cornerstones of Engineering: Electrical, Fabrication, Design, and Mechanical.

The department has expanded to four teachers, the school added an after-school automotive program, and several of Grosinger’s students have gone on to work in the automotive field. “Teachers should encourage students to explore new and more efficient ways to move a person from point A to point B, whether that system is a train with solar panels on it, a car with an electric motor in it or retrofitting an existing technology with a different energy source,” says Grosinger. “And don’t come up with the solutions for the students.”

Porsche Introduces Fully Electric Taycan; Sets New Standard for Driving and Charging Performance

“This day marks the start of a new era.”

With those words Oliver Blume, the Chairman of Porsche, today unveiled the eagerly awaited Taycan, a “100% electric, 100% Porsche.” The Taycan Turbo S and the Taycan Turbo will be the first in a new series of vehicles that are part of a massive transformation taking place at the iconic automaker. By 2022, the company will have invested more than six billion euros in e-mobility. Despite this apparent paradigm shift, Porsche is by no means deviating from its esteemed heritage.

We promised a true Porsche for the age of electromobility – a fascinating sports car that not only excites in terms of its technology and driving dynamics, but also sparks a passion in people all over the world, just like its legendary predecessors have done. Now we are delivering on this promise.

Michael Steiner, Porsche’s Executive Board Member for Research & Development

Performance

The flagship Turbo S version of the Taycan can produce up to 560 kW (750 hp) of overboost power with “Launch Control” enabled, while the Taycan Turbo produces up to 500 kW of power (670 hp).

Acceleration for the Turbo S is zero to 60 mph in 2.7 seconds, while the Taycan Turbo completes this sprint in 3.1 seconds. The top speed of both all-wheel-drive models is 162 miles per hour.

Range is superior as well: The Turbo S has a range of up to 256 miles, and the Turbo a range of up to 280 miles. The Performance Battery Plus is capable of storing 93.4 kWh of energy.

Charging

The Taycan is the first production vehicle with a system voltage of 800 volts instead of the usual 400 volts for electric vehicles. Higher voltage allows for lighter wiring; lighter wiring permits design flexibility, results in lighter vehicle weight, and enables higher charging speeds. This last point is a particular advantage when needing to charge up during long distance drives. The 800V system is capable of charging at a rate of up to 270 kW, which can provide 60 miles of range in about five minutes.

Charging an EV is similar to filling a container of water; the emptier it is, the faster you can fill it. This means that a charger will output the maximum amount of energy for the longest period of time when the battery is nearly depleted. When the battery is nearly full, on the other hand, a charger will dispense energy more slowly.

To take full advantage of the Taycan’s charging capabilities, then, a driver would strive to begin charging at a low state of charge (SOC). The charging time for 5 percent to 80 percent SOC with a maximum charge rate of 270 kW under ideal conditions is a mere 22.5 minutes. By comparison, a 50 kW charger would take about an hour and a half.

Image of 2020 Porsche Taycan charging port

The Taycan will come with the CCS DC Fast Charger port. This is not compatible with Tesla or CHAdeMO chargers, but most charging station developers other than Tesla, such as EVgo and Electrify America (a related company under the Volkswagen corporate umbrella), are deploying chargers capable of 150 kW and 350 kW.

At the moment, most DC fast chargers in the U.S. (other than Tesla) are only 50 kW, but the Taycan is backward-compatible, meaning it can use the legacy CCS chargers but will be able to draw only the amount of power the chargers are capable of dispensing.

For home charging, the Taycan can fill up at a rate of 30 miles per hour (for the Turbo S) and 33 miles per hour for the Turbo (which gets slightly better mileage than the Turbo S) using an 11 kW Level 2 charger on a 60 Amp breaker. Charging at that rate from 0% to 100% would take a little less than 8.5 hours.

Design

According to Michael Mauer, Head of Style Porsche, the company at first considered an SUV as its first fully electric vehicle, but ultimately decided that taking the first step with a sports car would make a clear statement “that this is the dawn of the new, purely electric era.”

Electric vehicles are typically higher than their gasoline counterparts due to battery placement, so sports car engineers must find a way to store the batteries while providing a comfortable seating position for passengers while maintaining the lowest possible center of gravity. Porsche’s solution is what Maurer refers to as his greatest challenge is “foot garages,” which are created by arranging the batteries in a staggered stair-step position.

Dispensing with a large internal combustion engine under the hood also allowed engineers to employ a look reminiscent of the iconic 911.

BMW Prepares for Electrified Future and Increased Electric Ranges With $10M Battery Investment

Battery being installed in BMW X5 xDrive45e at BMW Group Plant Spartanburg.

Readying itself for a slew of electrified vehicles, BMW Group announced this week an investment of approximately $10 million to double battery manufacturing capacity at the company’s factory in Spartanburg, South Carolina.

Spartanburg produces the company’s fourth-generation batteries, which provide improved energy density over prior generations. Maximizing energy density is beneficial because higher density provides more electric range in the same size battery.

For example, the battery in the 2019 plug-in hybrid model of the BMW 5 Series sedan is the same physical size as the prior version, but has a gross energy content of 12.0 kWh, up from 9.2 kWh. The benefit is 30 percent more electric miles while taking up no additional space in the vehicle.

Already a leader in vehicle electrification, up next for the U.S. market is the BMW X5 xDrive45e plug-in (up to 50 miles on electric power), which is expected to start production next month and is pictured above. The X3 xDrive30e plug-in (about 30 all-electric miles) is expected by the end of 2019, with a purely electric version due in 2020.

BMW plans to have 25 electrified models on the market by 2023; more than half will be fully electric.
