Electric vehicle innovations: A market snapshot
The future of transportation is here today. But to ensure that Canada’s and Ontario’s automotive sector remains competitive (or regains its competitive position), the sector players need to up their game.
General auto sales are on the rise in Canada and the US, and have been on the rise for some time. According to the Wall Street Journal Market Data Center, 1,281,313 light vehicle units were sold in the US market in October 2014 alone (and 1,455,516 light vehicle units were sold in October 2015)! By comparison, Frost & Sullivan (2015) data show that, globally, 304,953 electric vehicles (EVs) were sold in 2014, and projects sales to reach 2,337,748 units by 2020. See Figure 1 for the top 10 EV manufacturers in units sold.
Figure 1: Top 10 EV manufacturers, 2014
Electric vehicle sales are on the rise, yet remain a small percentage of cars sold (see Figure 2).
Figure 2: Canadian vehicle sales, 2012
However, automotive manufacturers (OEMs) are taking EVs more seriously. Just recently, in the aftermath of their huge diesel emissions scandal, Volkswagen slashed their projected spending for 2016 by one billion Euros, while increasing the portion of their investment in alternative drivetrain vehicles.
There are three main types of vehicles that can be classified as EV: battery electric vehicles (BEVs) that run purely on electricity, hybrids (HEVs) and plug-in hybrids (PHEVs)—the latter two combine electrical and internal combustion engines. In Canada, many different EV models are now available to consumers.
There is no perfect transportation solution. Even EVs have concerns, such as the higher upfront cost for consumers, variances in battery life and range anxiety (along with the lack of available charging stations).
Figure 3: Greenhouse gas emissions
Key EV advantages (particularly BEVs) include reduced greenhouse gas emissions (by 67-95% per vehicle per year for Ontario, but this depends on how the electricity used to power the vehicle was generated in other jurisdictions), cheaper energy costs to run (BEV energy costs are estimated to be three to five times lower than internal combustion engine vehicles) and lower overall maintenance.
Canadian policy drivers
In the US, the Corporate Average Fuel Efficiency (CAFE) standards include a fuel efficiency target of 54.5 mpg by 2025. Canada has imported this policy. Harmonization puts Canada’s automotive sector on equal footing with the US market, which is especially critical because Ontario has been manufacturing 16% of the vehicles for the North American market since 2010.
On November 24, 2015, the Ontario government released its climate change strategy. Of key interest to the transportation sector is the goal to reduce transportation emissions by promoting the uptake of zero emission and plug-in hybrid vehicles. The government also plans on introducing climate legislation that establishes a long-term framework for climate action. This legislation, if passed, would make Ontario’s cap and trade program law, and will act as a positive market driver for the Cleantech and automotive sectors.
Local governments can also set rules that can act as market drivers. For example, gasoline-fuelled cars could soon come under a new threat—climate change warning signs at the pump. The City of North Vancouver recently passed a bylaw imposing this requirement.
Overcoming barriers to wider adoption
The prices of oil and gas (and, subsequently, gasoline prices) fell drastically at the beginning of 2014 and remain relatively low today. Not all consumers have the planet in mind when they make purchasing decisions (not to mention having a rather short-term outlook). One can assume that with lower gas prices, consumers will give less thought to efficiency, which will consequently affect their vehicle purchasing decisions.
So, have low gas prices impacted EV sales? Bloomberg New Energy Finance (BNEF) data show a correlation between lower gas prices and lower sales of BEVs and PHEVs (see Figure 4).
Figure 4: US monthly EV sales and fuel prices, 2013-Q2 2015 in thousands of units
However, low gas prices are not likely here to stay. Weaker than expected demand and a supply glut have suppressed oil prices, but these factors are in flux; upcoming carbon prices will also affect oil prices once introduced more broadly. Also, at this stage, many EV owners are early adopters, and their purchasing decisions are arguably driven more by cool technology, brand mission (buying as much into the brand as the item itself) and environmental benefits than by pump price.
Auto tech and EV investment trends
According to CB Insights, there have been major investments in auto tech over the past five years. CB Insights defines auto tech as “companies that use software to improve the safety and efficiency in cars, specifically looking at assisted driving/autonomous software; driver safety tools; driving data/connected car; fleet telematics; vehicle-to-vehicle communication; and auto cybersecurity.” See Figure 5 for deal numbers and dollar value of auto tech investments.
Figure 5: Number of deals and value of auto tech investments, five years
Electric car investments, on the other hand, are not faring as well as software-based auto tech investments. Over the last two years, the average deal size for the EV investment category was around $7M (see Figure 6). It will be interesting to see the impact of climate change policy (such as the strategy Ontario just announced, along with the COP21 outcomes), and the imposition of carbon pricing in particular, on both the autotech and EV sectors from an investment perspective.

The internal combustion engine still reigns (for now)
Internal combustion engine (ICE) efficiency innovations from major OEMs pose a moving target for electric and fuel cell vehicle drivetrains, according to Lux Research. “The internal combustion engine currently reigns supreme, and manufacturers continue to work to extract every ounce of efficiency from it.” Internal combustion engine vehicles remain the true competitor to EV technology adoption. Elon Musk even went so far as to release Tesla’s patents, in recognition of this barrier to EV growth.
What can tech innovators and automotive OEMs do to drive greater pull for EVs and make it mainstream? For one, they could focus on innovating upon key consumer concerns:
- Reduce upfront cost
- Increase battery life
- Address range anxiety
- Improve charge station infrastructure
Groups such as Plug’n Drive are actively seeking to enhance the role of EVs in Canada by raising public awareness about EVs and charging infrastructure. They are also participating in and developing research aimed at driving greater adoption of EVs across Canada.
So how does a traditional automotive OEM function to bring new technology to market?
Ray Tanguay, Chairman of the Canadian Automotive Partnership Council (CAPC) sub-committee, said the following: “Any time you introduce new technology, you lose money. It’s a process of elimination. That’s how you find out how to improve it, and how to reduce the cost later on. The hybrid is a good example. Every generation of hybrid since 1999 has improved efficiency by 10%, with corresponding cost reductions.”
Hydrogen versus electric or hydrogen + electric?
Tanguay added that consumers feel that the price of entry to drive an environmentally friendly vehicle can be too high. Electric battery evolution is also too slow, as there are no new battery technologies in development that are expected to come out over the next 10 to 15 years. However, he sees hydrogen as a technology with potential. “The fuel cell is the better avenue, because we can produce hydrogen, we can charge hydrogen vehicles very quickly and it gives the range that you would get in traditional vehicles.”
There are many ways to generate hydrogen. It can be captured from manure, it can be derived from tree bark and it can be sourced from excess electricity. For example, Quebec generates a lot of hydropower, and sells its excess hydropower in bulk to the US market (and Ontario). “If excess power is stored in the form of hydrogen, then this hydrogen can be used to propel vehicles,” said Tanguay.
Ontario startup Hydrogenics is currently storing hydrogen derived from its electrolyzer technology. It uses excess electricity from wind generators to apply an electric current across water to separate water molecules into their component oxygen and hydrogen atoms, and then captures the hydrogen. They are now storing this hydrogen in the natural gas network with Enbridge in Ontario and E.ON in Germany. More recently, Hydrogenics has signed separate supply agreements with several Chinese electric vehicle integrators to bring its fuel cell and fuelling station technology to China (see Figure 7).
Figure 7: E.ON Power-to-Gas facility in Falkenhagen with Hydrogenics technology
Tanguay believes that the smart city concept is the ultimate role model for cars. “I see a bright future for the fuel cell vehicle, and I see electric vehicles for small, short distances. The car has to be an integrated part of city infrastructure, where it can use and store energy.”
Cost of batteries
Hydrogen has a future in our transportation sector. There is also a key opportunity for hydrogen to knit together our power and natural gas grids, enabling greater integration of renewable resources into both these energy networks.
Tanguay sees a more defined role for EVs. “Given urbanization trends around the world, I think the future is shaping out to be more flexible, distributed and decentralized.”
Battery prices are coming down. According to the Deutsche Bank report “Crossing the Chasm,” energy storage companies are expected to significantly reduce energy storage costs by 20–30% per year over the next five years. The report states that this “could bring conventional lithium ion batteries at commercial/utility scale to the point of mass adoption potential before 2020.” It also stated that incremental storage costs will likely decrease from about $0.14 per kilowatt-hour to $0.02 per kilowatt-hour within the next five years (see Figure 8).
Batteries currently comprise a significant percentage of an EV’s cost. Any improvements in battery efficiency and reductions in battery size will help to significantly reduce overall EV cost. With the high cost of EV ownership as a major deterrent, reducing this cost will help to entice consumers to switch from ICE to electric vehicles and encourage the car-less to consider EV ownership.
Powertrain: Introducing innovation to a traditional sector
“To meet a target of 54.5 miles per gallon by 2025 will require a different kind of power train.” ~Ray Tanguay, Chairman, CAPC sub-committee
Innovation goes beyond battery or fuel cell technology and infrastructure focus. Efficiency can be greatly improved by adopting technologies that improve power conversion. For example, improving power conversion can reduce battery size requirements.
inMotive developed a transmission for electric vehicles, which sets it apart from other types of transmissions that are designed for internal combustion engines. inMotive CEO Paul Bottero expanded, “There are no passenger BEVs right now with transmissions. The reason is that none of the transmissions that have been designed for internal combustion engines perform well or are cost-effective in an electric vehicle.”
A transmission is part of the drivetrain. An EV’s powertrain starts with the batteries. Batteries power the motor, which traditionally powers the wheels directly through a reduction gear and axles. However, replacing a simple reduction gear with a transmission between the wheels allows the motor to operate more efficiently. With a motor operating more efficiently, you draw less on your batteries, which improves range.
Said Bottero, “That’s a primary benefit of our technology—range improvement—but there are other benefits too. Using the motor more efficiently means you can accelerate faster, get higher top speed, improve passing power and be able to climb hills, all of these performance characteristics are improved with a transmission system.”
One of EVs’ greatest challenges is that they are range limited. There are several ways to address this challenge. For example, you could add more batteries, but this is an expensive and heavier option, which increases weight and decreases efficiency. Using lightweight materials can also reduce vehicle weight. Explained Bottero, “For a relatively low cost, using inMotive’s transmission could lead to a fairly dramatic improvement in range. We are looking at 10 to 15% range improvements, with an incremental cost that is a fraction of the cost of the batteries.”
Charge it up: Charge station infrastructure is increasingly connected and utilities are on board
Much has been reported on the status of innovation in the refuelling or recharging infrastructure for alternatively powered vehicles. The Canadian Automobile Association (CAA) & ChargeHub have developed a map of publicly accessible charge stations across Canada. There is an infrastructure deficit for hydrogen car fuelling and, to a lesser extent, EVs. Super chargers are not found on every corner like gas stations, but charging options are plentiful when you account for the residential sector. Electricity is everywhere, at least in key automotive markets. Hydrogen facilities, on the other hand, have some catching up to do.
There are two key electric charge station segments: residential—which will likely become a commodity market at some point—and the commercial sector, where business models are still being explored.
I spoke with Sassoon Peress, CEO of Renewz, about his startup. “We’re involved in the smart vehicle industry from the electrification side. We work with site owners to develop solar-powered electric vehicle charging stations. All of the projects that we develop include both the solar component and the EV charging component.”
Peress shared some of his long-term, high-level perspective: “Everything can be connected, which means that everything can be controlled. The minute that everything can be controlled, then it’s just a question of determining who is the conductor. Who’s going to determine what appliance gets turned down, what appliance gets turned up, what energy source gets turned down, what energy source gets turned up, what storage source is used, what storage source is not? While everything can be connected, they still need to be conducted.”
With the growing number of electric vehicles and connected cars, the rise of renewable energy, energy decentralization trends, and the fusion of energy and IT, new players continue to arrive on the scene. This is leading to a growing battle between traditional utilities and automotive companies and the next generation of automotive companies and utilities.
Peress used Florida as an example, which passed a law that restricted going off-grid. Florida utilities are competing with new utilities such as Solar City, which supports independence from the utility grid. “Here’s solar on your roof and now here’s the Powerwall from Tesla because they’re sister companies. Now you’ve got what you need to be off the grid all the time.” He continued, “What becomes the revenue source for a utility company that has banked on 50 years of capital depreciation for the huge infrastructure that they’ve put in? That’s the first sector side. The automotive sector at the same time is moving to mobility services as opposed to selling cars.”
This is where it gets complicated. There are now car sharing market players like Uber, Lyft and Split (more on the impact of the rise of the sharing economy on the automotive sector in Paul Barter’s December blog) and they are doing well. With the next generation caring more about mobility services than owning an asset, car companies will have to revisit their business models. The sharing economy could have a significant impact because car ownership isn’t what it used to be, at least in North America. To previous generations, owning a car was a big deal.
We don’t know what the future holds. For Bottero, Uber or Google could become the world’s largest owners of cars in the future (through fleet buys), and Google could displace Uber if they get the core self-driving technology right (although Uber is investing heavily in autonomous cars too). So cars might not be driven or owned by people in the way that we are used to. “They could be owned by corporations and be driven autonomously. It could be a very different future on the roads. I think the great thing about the sharing economy is that it is still evolving and no one knows how it’s going to end up. It could be a very exciting future.”
While services like Uber are disrupting the automotive sector, new automotive market players like Tesla are entering the utility space.
Peress believes that as electric vehicles get spread out, they can also become power banks. Every electric vehicle can become a power source. Peress was most interested in this mix – this new complexity in competition with the entrance of automotive market players into a traditionally utility-held space, and competing for the residential customer. “There’s a real shift occurring and if you don’t stay ahead of that curve, you’re going to become a dinosaur.”
Cars, as well as electric vehicle charging stations, are becoming part of the Internet of Things (IoT). Like cars, charge stations are becoming connected and controlled, which enables them to participate in broader demand management programs, a trend across the rising energy Internet.
See our Connected World Series paper, “The Evolving Digital Utility: The convergence of energy and IT,” for more on the energy Internet.
Electric vehicles stand to become a significant demand management opportunity. At the other end of that scale, if utilities are not ready, and consumers all plug in their cars when they get home at 6:00 PM, these EVs could overload a transformer and the local distribution grid. One way to charge EVs is to turn to smart charging, which avoids spikes or peaks in power demand. Forward-looking smart charging would enable the use of EV batteries as storage for the utility’s valuable grid services, while also allowing for greater renewable energy integration. For more on smart charging, see this EUROELECTRIC paper.
There are several key challenges for the EV charging infrastructure at the commercial level. For example, chargers must be compatible with different EV models and manufacturers, and consumers will have to avoid dealing with proprietary payment options and multiple payment systems.

The convergence of connected car features with the EV
“Having the automated vehicle is actually the true meaning of automobile. Right now we just have the mobile. It’s kind of interesting that after how many years we now are finally just laughing about making a true auto-automobile.” ~ Ray Tanguay, Chairman, CAPC sub-committee
According to Lux Research, all automakers are ramping up development efforts for EVs, and many automakers have plans for connected and autonomous cars. Some automakers are beginning to combine these two development streams. Autonomous features, a cross-over tech from the connected car, could add significant savings for EVs by extending range.
For more on the connected car, check out the second part in our Smart Transportation series: “The Connected Car: Remaking the transportation and mobility experience.”
The future of transportation is already here
The future of transportation is connected, alternatively powered and automated. I doubt that there will be a one-size-fits-all solution. What works for an urban area might not work for a rural area. For example, Uber-type business models might not be as prevalent as carpooling options, and the personal automobile might not be going anywhere anytime soon given our recent history with suburban sprawl and its reverberating impacts. Our automobile might become truly automatic over time, and will increasingly shift toward alternative power sources.
The core technologies for the future of transportation are mostly in place or are being invented right now. It’s now up to society to wield markets and unleash human capital and ingenuity to make our transportation networks truly smart and sustainable. Climate change strategies, fuel efficiency regulations, a price on carbon and the rollout of renewable energy technologies are just the beginning. A lot more change is coming – and those that embrace the future, the now, are most likely to truly benefit.
