The electric car will facilitate the smart grid and a renewable energy charging infrastructure. The electric car will help make the smart grid relevant to consumers. Right now most cars use inefficient engines fueled with gasoline or diesel. In the coming decades, many cars will use electricity. With a smart grid, renewable energy will do much of the charging.
New electric cars from Nissan, Toyota, GM, Ford and others will use a charging standard J1772. The new charging units at home and work will include a smart meter chip. When a driver plugs-in, charging will follow preferences pre-established by the car owner. Many will prefer to save money and charge at night when rates are cheaper.
States with the earliest adopters of electric cars are also states where utilities face big renewable portfolio standards (RPS). The lowest cost renewable per megawatt is wind, but much of the wind turbine power is delivered at night when winds are most constant. With a smart grid and price incentives, electric cars will be charged off-peak using renewables.
The promise of smart grid electric vehicle charging was discussed at the GreenBeat 2009 conference last week by technology leaders such as Google and Cisco, and utility leaders such as Duke Energy and Southern California Edison. Al Gore presented smart grid and super grid findings from his comprehensive new book about climate solutions – Our Choice.
The current Smart Grid 1.0 is frankly boring. Smart Grid 2.0 promises to make our life better with less use of damaging coal power emissions.
With Smart Grid 1.0, new electric meters are being installed. Utilities save because they no longer need to send people out to read meters. Services can start and stop without rolling trucks to make manual connects and disconnects. Utilities are saving while the consumers pay for the new meters with rate hikes.
As the smart grid conference unfolded, a class action suit unfolded against PG&E, the leader in installing smart meters. The suit filed last week in Kern County Superior Court claims that Pete Flores’s electric bill jumped from $200 per month to over $500 per month after his smart meter was installed. Is it possible that those old mechanical meters sometimes underreported actual electricity use? Are we running more AC with hotter temperatures? We will find out as the suit unfolds. In California higher use can push people into higher pricing tiers.
My wife and I keep our PG&E electric bill under $25 per month by living in a well insulated condo, where I replaced all lights with CFL. Marcia also patiently tolerates living with an environmental journalist that turns off anything not used in the past 30 seconds. Our rate is only 11.5 cents per kilowatt hour. Bigger users in top tiers can pay three times that rate. Pricing works. California has kept electricity use per capita flat, while it has stored in most states.
Electric utility industry has shifted from years of falling costs to rising costs. Utilities need to shift energy use and vehicle charging off-peak to avoid unnecessary investments in expensive peaking power plants. A smart grid is needed to fully utilize renewable energy and moderate fossil fuel emissions.
Energy efficiency and demand management is already saving some enterprises millions per year. Most state public utility commissions (PUC) are afraid of implementing consumer time-of-use (TOU) pricing to give people the incentive to use energy when it is plentiful not scarce. The latest class action lawsuit hardly encourages PUCs to act more boldly.
Public utility commissions are more willing to allow pricing incentives for vehicle charging. Electric cars will help move us to Smart Grid 2.0. Through web browsers, smartphones, and vehicle displays, drivers will select smart charging preferences and get feedback on how to use less electricity and save money. Early electric cars will cost more than their gasoline counterparts, but their electric charging will cost a fraction of the cost of gasoline fill-ups.
Currently, there are only 40,000 electric cars running in the United States. As exciting new offerings are being tested and sold, 1.5 million electric cars are expected in the U.S. by 2015 presented Sharon Allan, the Senior Executive, North American Smart Grid Practice, for Accenture.
Charging these electric cars will help transform the promise of a smart grid into a convenient cost-saving reality.
SEV connects to Smart Grid with J1772
By John Addison (8/20/09).
The new freeway-speed electric cars will also be intelligent. They will be smart about using energy inside the vehicle so that it can go 100 miles between charges. The plug-in electric vehicles (PEV) will be smart about navigation options that consider your preference for getting somewhere fast or traveling with minimal energy use. PEVs will be full of electronics to entertain passengers, like kids in the back seat.
They will be smart about charging to meet driver preferences for saving money or charging more quickly. Smart electric vehicles ideally use a smart grid for charging. The electric utilities see the electric vehicle as part of the new smart grid which uses information technology to make the electric grid efficient, reliable, distributed, and interoperable. Years ago, mainframe computers with dumb terminals gave way to network computing. Similar improvements are now underway with the electric grid.
At the Plug-in 2009 Conference and Exposition in Long Beach, I joined thousands in seeing new electric vehicles, new smart charging stations, and joining presentations by leading auto makers, utilities, early fleet users, and sustainable city leaders from Southern California Edison, SDGE, AQMD, EPRI, and many others.
At the Plug-in Conference, the new Nissan Leaf got a lot of deserved attention. By the end of 2011, Nissan may deliver as many as 10,000 of these. Most will be delivered where utility and other partners have committed to complete programs to install garage, employer, and other public charging stations.
The new 2010 Nissan Leaf is a comfortable compact hatchback that seats five. Clean Fleet Report’s test drives of Nissan EV prototypes demonstrated plenty of acceleration. The Nissan Leaf is powered by 24kWh of lithium-ion batteries. The Leaf has a range of about 100 miles. In 8 hours you are good for another 100 miles with a Level 2 AC200V home-use charger; in 26 minutes you can be 80 percent charged with a Level 3 DC 50kW quick charger.
Transportation expert, Antonio Benecchi a Partner with Roland Berger forecasts that plug-in hybrids and electric vehicles will capture 10 to 20 percent of the auto market by 2030. The speed of adoption will depend on cost and early customer experience. If the lifetime cost of owning and operating an electric vehicle is less than a comparable gasoline powered one, 20 percent could be low by 2030.
When you get an iPhone, Nokia, or Blackberry, the cost of the smartphone depends on the type of subscription plan you have with the wireless carrier. Similarly, over the next few years, automakers and their partners may explore different business models such as:
· Vehicle purchased with battery leased
· Vehicle, battery, and energy for charging are all subscribed
· EV and charging are part of carsharing plans
· Integrated mobility offerings will include an EV
For example, the Nissan Leaf might be offered by a dealer for under $30,000 with battery and charging offered on a subscription plan by Better Place or various electric utilities.
If charging and subscription plans are kept simple, consumers will love it. If consumers must sign for different plans as they go to different cities, EVs will be a turn-off. Early cell phone users rebelled against complicated plans and big surprise “roaming” charges.
Standards are being put in place so that auto makers, charging station providers, and electric utilities will be compatible. A key standard is automotive SAE J1772, which standardizes the electrical connection, current flow, and some communication between smart vehicle and smart charger. This standard is compatible with important advanced metering smart home electric standards such as Smart Energy 2.0.
EV customers will be able to check on how much their EV batteries are charged through a web browser, their smart phone, or by looking at their vehicle dash. The networking and software is there, so that they could look at monthly vehicle use and charges.
Electric utility operators will be able to track, manage, and forecast EV electricity use thanks to smart charging stations with electric utility meter chips built in such as Coulomb ChargePoint Networked Charging Stations and ETEC, who has already installed over 5,500 charging stations. ETEC will be installing over 12,500 new charging stations thanks to a matching grant of almost $100 million from DOE.
I am on the wait list to buy the Nissan Leaf. When I get a new EV or PHEV, I would be glad to agree to a subscription plan that would save me $100 per month if I would agree to have my vehicle not charge during peak-demand hours. We’ll see if I am given that kind of option. Thanks to software services from GirdPoint and others, the technology is there to plug-in and having charging managed by user preferences and subscription agreements.
Utilities could shape demand to off-peak. Utilities could use EVs for spinning reserves and peak power using vehicle-to-grid (V2G). Dr. Jasna Tomic with CALSTART estimates that the national grid would only need 7 percent additional capacity to off-peak charge 100 million electric vehicles. Those same vehicles could provide 70 percent of the national grid’s needed peak power. Smart grid upgrades, customer price signals and subscription agreements could enable growing use of V2G in the coming decade.
Smart vehicles and smart grids create a trillion dollar opportunity for incumbents and innovators. The opportunity has attracted GM, Ford, Toyota, Nissan, and hundreds of other auto makers. It has attracted the world’s largest electric utilities and grid operators. This smart grid “Internet” for electricity now has devoted teams inside IBM, Google, Cisco, Microsoft, and other information technology giants.
Intelligent electric cars are symbiotic with the smart grid. The communication technology is here. It is the business models and customer experience that count. Get ready for the most comfortable and intelligent ride of your life.
