Infographic: Vehicle-to-Grid (V2G) Power Storage. Why Electric Vehicles Matter!


Renewable energy sources like solar and wind only generate electricity when the wind blows or the sun is out and that isn’t always when customers need power. Batteries large enough to hold megawatts of electricity are prohibitively expensive but another potential source of battery storage is fast emerging: electric vehicles.

Vehicle-to-grid (V2G) storage allows the smart grid to use EVs (and even hybrids) as a distributed network of batteries that can store power at off-peak times and help power the grid when demand peaks. Here’s how it works:

1. Power is generated from a renewable source, like wind, and transferred to the grid.

2. Electricity flows from the grid to EV batteries when there is excess capacity (e.g. when the wind blows in predawn hours). The power flow is reversed when demand on the grid is higher.

3. Customers can control when the smart grid can access battery power from their EVs, which can put out enough power to run 10 houses, and even control how far the battery is discharged.

BMW i3 Rex package Review

No wonder why this car is flying off the shelves like hot cakes. All electric and then gas backup to power only the electric motor giving over 70 MPG!  Let’s not forget luxury and refinement not seen in other electrics. Last year alone they sold almost half off what the Nissan Leaf has sold worldwide.

BMW i3 electric car Eucyliptus Dashboard

The Drive Module, which is constructed out of 100% aluminum, consists of the 22-kWh, 450 lb. lithium-ion battery, electric drive train, MacPherson struts and 5-link rear suspension system (plus structural and crash components).  Just to be clear these were great struts and shocks in the winter snow too.

The stability to the car is added with the battery packs holding down the vehicle in the rear; close to the drive wheels. This totally gives an impressive ride: way better than expected. Forget it driving like a BMW but in the winter test it had way better traction than expected.

Drove Superbowl Sunday Night and it Snowed. no problem!

As I wrote in my review on

Driven and tested during Superbowl weekend: the official 2015 BMW i3 all – electric with range extender car launch. The BMW i3 range extender (REx) is an interesting car in many ways. The all EV drive system is very impressive. It gets 80 miles all electric and 85 miles gas backup or fill up. 85 percent of all trips are within that range, so the majority of the time it’s all EV.

First Fast Charging EV Bus Hits Road


Ecoliner charges in 10 minutes; zero-emissions

WEST COVINA, CA (August 26, 2010) – Foothill Transit, the primary public transportation provider for the San Gabriel and Pomona valleys in Los Angeles County, is launching the world’s first heavy duty, fast charging electric bus on Friday, September 3rd.

The Foothill Transit Ecoliner is a lightweight vehicle with heavy duty responsibilities, driving 30-miles without charging, and will be recharged, hands-free and within its route, in 10 minutes.  This public transportation vehicle is the first of its kind in the nation.

“Recent rapid advancement in battery and vehicle technology has made this leading edge project possible,” said Roger Chandler, Chair of Foothill Transit’s Executive Board.  “And the challenges that we face with our environment demand that we expand beyond what’s available into what’s possible.  This is the time and place for possibility.  Excited doesn’t begin to describe how we feel.  This is history.”

The project is entirely funded through the American Recovery and Reinvestment Act of 2009 (ARRA) and will be deployed on Foothill Transit’s Line 291, which travels between La Verne and Pomona.

The Ecoliners will recharge about every 30 miles at the Pomona Transit Center at a drive-in docking station. During the project’s life, both Foothill Transit and Proterra LLC, the Ecoliner manufacturer, will monitor the Ecoliner’s ability to handle the demands of a regular, stop-and-go transit route during the trial period.

“This project is taking the lead in changing the transit world,” said Dale Hill, Chairman of Proterra LLC.  “Foothill Transit is leading that change for the nation, and we’re excited to be a part of that.”

Proterra Launches First Deployment of All-Electric, Zero-Emission Buses by Major Transit Agency

Leading Heavy-Duty EV Bus Manufacturer Provides Cost Effective, Comfortable Green Commercial Transit Solutions to Southern Californians

  • Proterra EcoRide bus to serve one of Foothill Transit’s busiest and most challenging routes
  • Helps California transit agencies meet mandated 15 percent zero emission bus target
  • Introduces enhanced experience for bus riders with reduced air and noise pollution

Golden, Colo. – August 31, 2010 – Proterra Inc, a leading maker of zero-emission commercial transit solutions, today announced the first major deployment of its EcoRide BE35™ zero-emission, fast-charge battery-electric transit buses by Foothill Transit, a premier public transport provider that operates bus services in the San Gabriel and Pomona Valleys, located in the eastern portion of Los Angeles County. On Sep. 3, Foothill Transit will launch the Proterra EcoRide BE35™  buses and related fast charging stations into its existing bus fleet and transit routes with the goal of establishing a full fleet of clean-fueled vehicles by 2011.

“The first commercial deployment of Proterra’s battery-electric buses by a major transit agency like Foothill Transit is a significant milestone for Proterra and a bold step by the nation in our collective effort to decrease dependence on fossil fuel,” Proterra President and CEO Jeffery Granato said. “We look forward to additional communities throughout the U.S. and globally benefitting from the highly efficient, cost effective, clean alternative transit solution now available with the introduction of the EcoRide BE35™.”

The deployment of Proterra’s EcoRide BE35™ buses, known as the “Ecoliner” by Foothill Transit, greatly advances the electric transit industry, providing a real-world example of the benefits and ease of deployment of Proterra’s zero emission buses and charging solutions. It further demonstrates transit agencies’ existing appetite for cleaner commuting options. In addition to its unmatched performance and overall cost savings, Proterra’s clean transit solutions offers California transit agencies solutions to address the Zero Emission Bus (Zbus) regulation, which requires large California agencies to purchase 15 percent of their annual bus orders as zero emission buses starting in 2012.

Additionally, without the maintenance or fuel costs associated with conventional buses, the Proterra BE35™ achieves a 400 percent improvement in fuel economy, and greater than $300,000 savings in total lifetime operating expenses.

EV buggy Tackles famous “Race to the Clouds” on ADVAN® ENV-R2™ slicks, the world’s only eco-friendly race tire

Cuts energy use of Electic vehicles by by 20 percent

FULLERTON, CA (June 16, 2010) – Yokohama Tire Corporation’s ADVAN® ENV-R2™ orange oil-infused race tires have another mountain to conquer…literally. Already the official spec tire in the IMSA Patrón GT3 Challenge by Yokohama and the new ALMS GT3 Challenge (GTC) Class, the ENV-R2 is now poised to take on Pikes Peak in the new Electric Vehicle Class, June 27.

Once again, Yokohama tires will be on a Sanyo battery-powered electric buggy driving a new AC Propulsion engine in the Pikes Peak International Hill Climb. Last year with Japanese driver Ikuo Hanawa behind the wheel, the Yokohama-sponsored EV buggy sported off-road Geolandar® tires and placed second in its class, just missing the EV world record by 13 seconds. Hanawa is back piloting the new EV Sports Concept HER-02 buggy, but this time it will have the ENV-R2 tires, which cut petroleum use in the manufacturing process by 20 percent by utilizing sustainable resources such as orange oil and natural rubber.

“Yokohama is the only tire company to have perfected this science,” said Mark Chung, Yokohama director, corporate strategy and planning. “The ENV-R2, the world’s only environmentally-friendly race tire, is campaigned on Porsche 911 GT3 cars in two sports cars series, including an endurance race.”

Chung said “the Pikes Peak race is a different beast, but we feel the ENV-R2 will handle the hill quite well. And the fact that the orange oil tires are on an electric race vehicle is perfect for Yokohama. It certainly fits our longstanding commitment to innovation, technology and the environment.”

The orange oil technology developed by Yokohama’s motorsports division is part of the company’s overall global environmental strategy. The proprietary technology, which combines orange oil with natural rubber to form a new compound called “Super Nano-Power Rubber,” is used in race tires and Yokohama’s dB Super E-specTM, an everyday passenger car tire that debuted in July 2009. 

Celebrating its 40th anniversary in the United States, Yokohama Tire Corporation is the North American manufacturing and marketing arm of Tokyo, Japan-based The Yokohama Rubber Co., Ltd., a global manufacturing and sales company of premium tires since 1917. Servicing a network of more than 4,500 points of sale in the U.S., Yokohama Tire Corporation is a leader in technology and innovation. The company’s complete product line includes the dB Super E-spec™ – the world’s first tire to use orange oil to reduce petroleum – as well as tires for high-performance, light truck, passenger car, commercial truck and bus, and off-the-road mining and construction applications.
