Automakers Expanding From the Garage to the Home with Energy Storage

— September 1, 2016

Lithium BatteriesAs the residential energy storage industry continues to take shape around the world, the landscape of companies involved is becoming increasingly diverse. While the industry is still in nascent stages, the number of new companies entering the market (and their differing backgrounds) is growing. Companies offering dedicated residential energy storage products include battery pack manufacturers, inverter manufacturers, software providers, solar PV vendors/developers, and automotive manufacturers. With the growing popularity of EVs, it comes as no surprise that automakers are looking to leverage their battery expertise to develop complementary products. These companies are eyeing a piece of the residential storage market expected to be worth $5.4 billion annually by 2025, according to Navigant Research’s Residential Energy Storage report.

In June 2016, after months of speculation, automaker BMW officially announced a residential energy storage product featuring the same batteries used in its i3 vehicles. The company joins several of its competitors that have already repackaged their vehicle batteries into home energy products. Fellow German automaker Daimler already offers Mercedes-branded home battery systems, and Nissan offers a similar product through a partnership with energy technology specialist Eaton. These companies are not alone; EV pioneers Tesla and BYD both have dedicated residential energy storage products and are actively working to expand in this area.

Seeking Advantages

Automakers see several advantages as they enter the increasingly crowded market for residential energy storage systems. Customers looking to purchase or lease EVs may be prime candidates for purchasing residential energy systems. The ability to upsell EV customers to also purchase home battery systems could provide a lucrative sales channel with lower customer acquisition costs than competitors. Additionally, automakers are actively working to position themselves within the emerging vehicle-to-grid space. Both BMW and Nissan have announced vehicle-to-grid pilot projects with power providers Pacific Gas & Electric and Enel, respectively. These programs seek to utilize the available capacity in EV batteries and the flexibility of EV charging to help alleviate congestion and reduce peak demand on the grid.

Furthermore, automakers may have a distinct advantage in the coming years through low-cost access to repurposed EV batteries. Some companies have already capitalized on this resource through partnerships with storage project developers to supply these used batteries at a competitive price. According to analysis in Navigant Research’s Alternative Revenue Models for Advanced Batteries report, “the effective energy capacity available from EV [lithium ion] batteries for second-life stationary energy storage system applications is projected to exceed 1 GWh per year in 2022.”

Across the growing energy storage market, new players are entering and looking to leverage their expertise from a variety of complementary industries. Automakers are not alone in having identified the advantages their existing businesses will provide as they compete in the energy storage market. Solar PV providers, energy service companies, and even utilities are all seeking to leverage their customer base and technical expertise to provide the most attractive and cost-effective solutions in this rapidly evolving market.

 

Progress on Automotive Cyber Security, but Still Much to Do

— August 8, 2016

CarsharingWhen I joined Navigant Research two years ago, I sat down on my first day and wrote a post on this blog about automotive cyber security. At that point, most of the industry was still largely refusing to acknowledge that cyber security was even something to be concerned about. Things have changed quite dramatically since then, but there is still a long way to go, as recent news shows.

All of the major automakers except for Tesla have come together to establish the Automotive Information Sharing and Analysis Center (Auto-ISAC). Like ISACs in other industries, the Auto-ISAC provides a mechanism for manufacturers to share non-competitive information about security threats and collaborate on understanding and correcting these vulnerabilities. Since the Auto-ISAC started operations at the end of 2015, it has also begun to add suppliers to its member ranks.

Developing Best Practices

At the recent Billington Automotive Cybersecurity summit in Detroit, the Auto-ISAC announced the development of a set of cyber security best practices for the industry. Industry executives and regulators—including General Motors CEO Mary Barra, National Highway Traffic Safety Administration director Mark Rosekind, and Secretary of Transportation Anthony Foxx—discussed the importance of designing for cyber security and what is being done to address threats.

In August of 2014, Tesla was taking the lead on hiring white hat hackers to work on security from inside, and other companies are now doing the same. Tesla, GM, and Fiat Chrysler Automobiles have all established responsible disclosure programs that provide a means for researchers to submit information about vulnerabilities they have discovered.

A pair of Silicon Valley startups, HackerOne and Bugcrowd, have developed platforms for submission and vetting of vulnerability disclosures that are used by these automakers as well as dozens of other technology companies. Bugcrowd has also developed a reputation system for researchers that submit vulnerability information and works with client companies to select groups of white hat hackers to conduct pre-release testing on new products.

Numerous startups including Karamba Security, Argus Cyber Security, and TowerSec have popped up in recent years to develop both hardware and software solutions to help detect and stop intrusions from malicious attackers. Since everyone familiar with cyber security acknowledges that no complex system can ever be guaranteed as secure, manufacturers are also working on resilience to keep vehicles safe in the event of an attack and be able to update them quickly after vulnerabilities are found.

Navigant Research’s Automotive Cyber Security report projects that by 2025, more than 45 million vehicles annually will have telematics capabilities that enable over-the-air software updates, just as Tesla does today on its vehicles.

Vulnerabilities Continue

Despite the progress, recent news shows that there is still much work to be done on existing vehicles. In Houston, Texas, a pair of car thieves have been arrested after stealing 30 Jeeps in 6 months by hacking the vehicles’ ignition systems with a computer. Charlie Miller and Chris Valasek have again hacked a vehicle, taking control of the steering and brakes. After FCA corrected the vulnerability that enabled last year’s remote hack, they connected a computer through the onboard diagnostic port this time.

Yet another group of researchers have even demonstrated how a signal generator could be used to provide false reflections and fool the radar sensor of a Tesla with its AutoPilot driver assist active.

There will be undoubtedly be many more such demonstrations in the coming years as vehicles get more sensors, more connectivity, and more automation. From here on out, the industry can no longer afford to relax and will have to remain vigilant and ready to respond quickly to threats. Fortunately, they seem to be doing just that.

 

John Krafcik Takes the Steering Wheel of Google Car Project

— September 29, 2015

Someday, Google’s vision of cars without steering wheels, accelerators, or brake pedals may come to fruition. For the foreseeable future, however, intelligent people will still be necessary to guide the process of actually developing and building those machines. Incidentally, Google has just hired one of the smartest in the business, John Krafcik. The former Ford, Hyundai, and TrueCar executive is now the CEO of Google’s self-driving vehicle program.

As the former head of product planning and later CEO of Hyundai Motor America, Krafcik demonstrated his ability to run an operation that develops, manufactures, and markets vehicles to a mainstream audience. Prior to his decade with Hyundai, Krafcik spent 14 years at Ford, where he is reputed to have coined the term “lean manufacturing” in an article he wrote while working on his MBA at MIT.

Navigant Research’s Autonomous Vehicles report projects that by 2025, approximately 45 million light duty vehicles with at least Level 2 semi-autonomous capability will be sold globally every year. Level 2 is defined as a system that can automatically control at least two primary functions—such as steering and speed. Widespread adoption of Level 4 systems that can handle all primary driving functions without human intervention are unlikely before the 2030s.

Google and the Automotive World

For Google, Krafcik brings a reality check to the company’s automotive ambitions. Unlike Google’s primary businesses, the automotive industry is one of the most heavily regulated in the world, and the product can put lives at risk. Representatives from several manufacturers have acknowledged that they have been approached by Google about partnering on autonomous vehicles. However, Google’s approach so far has been to have manufacturers supply a vehicle platform while Google provides a black box of software that the manufacturers have neither control nor influence over. Given the many unresolved legal and ethical questions around autonomous vehicles, this approach has been rejected so far.

Krafcik knows how the auto industry functions and why it so often appears to be extremely conservative in rolling out state-of-the-art technology. He has a keen understanding of how to mass manufacture vehicles in high volumes and what mainstream consumers want in a vehicle. At the same time, he is an acknowledged risk taker in taking his companies into new market segments. Under his leadership at Hyundai, the brand steadily expanded from a second-tier purveyor of value, building credibility with consumers and critics so that it can now sell luxury cars like the Genesis without being laughed at.

Krafcik’s Credentials

This writer has known Krafcik for 8 years and he is clearly an engineer and manager that appreciates a challenge. Prior to being promoted to CEO at Hyundai’s American branch, the office had a rotating door of occupants who struggled with the home office’s demands. Krafcik managed to occupy the post for an unusually long 5 years and is likely the best candidate that Google could have hired.

Chris Urmson will continue leading the technical development side while Krafcik opens possibilities as this project evolves into a real business. Krafcik is well-respected in the industry, and if Google decides to pursue OEM partnerships, he is far more likely to be successful in brokering deals than those that have a distinctly Silicon Valley mindset. On the other hand, if Google opts to get into the manufacturing of cars, Krafcik knows that side of the business equally well—whether Google wants either its own factories or a contract builder like Magna Steyr to handle the work. Whichever path Google takes, the future looks interesting. And that is said without even knowing if Apple will get involved.

 

PEV Sales Grow Everywhere … Except Where They Started

— August 20, 2015

When the Nissan LEAF and the Chevrolet Volt were introduced in late 2010, plug-in electric vehicle (PEV) sales were concentrated on the respective automakers’ domestic markets, Japan and the United States. Japan was the largest PEV market in 2010, was quickly overtaken by the United States in 2011, fell behind Western Europe in 2012, and then behind China in 2014. Meanwhile, the United States has maintained a lead on China and Western Europe, but it’s possible that like Japan, it too will fall behind China and Western Europe this year.

In the first 7 months of 2015, PEV sales in the United States are down 6.3%. Many of the compliance PEVs made by Toyota and Honda have been phased out, while production of higher-volume PEVs has slowed before the introductions of the next-generation updates scheduled to be released before the end of the year. Similarly, only one new PEV has been introduced this year, the Mercedes S550 PHV, which is a high-end luxury vehicle likely to be sold at low volumes. The limited amount of new vehicle introductions is a stark transition from 2012, 2013, and 2014, where over the course of each year, around six new PEV models were deployed.

Meanwhile, in China and Western Europe, PEV sales in the first 6 months of 2015 are estimated to be up 175%, and 77%, respectively. The surge in China and Western Europe can be attributed to PEV introductions from an influx of domestic automaker platforms alongside significant government incentives in select Chinese cities and European countries. Volkswagen, Mitsubishi, and BYD have been particularly aggressive in these markets. In addition, the oil price dive has been less impactful on retail fuel prices in these markets than in North America due to higher taxes on retail fuels in these markets.

Though the North American market is slowing relative to China and Western Europe, annual growth is likely achievable by the end of the year. Despite some delays, a number of new PEV models are set to be introduced in the next few months. Among the introductions are three SUVs: the Volvo XC90 T8, the Tesla Model X, and the BMW X5 eDrive, which will help break PEVs into new high-volume markets. Similarly, the redesign of the Chevrolet Volt, which increases the vehicle’s all-electric range and internal combustion engine fuel efficiency at a lower purchase cost, is set to go into production this month.

However, for Japan, growth is likely negative in 2015; the market has contracted over 20% over the first half of the year. This puts Japan in line to fall behind Norway, the United Kingdom, and France, with Germany closing in. Most of Japan’s PEV sales come from domestic automakers Nissan and Mitsubishi. Toyota and Honda have been reluctant to sell PEVs, favoring fuel cell technologies instead. With BMW and Tesla being the only foreign PEV automakers making sales in the country, PEV availability in Japan is severely limited.
