CEO Corner, Point of View
Our Mission? Zero Emissions!
After participating in a number of recent customer presentations, I’ve come to realize that there is still a lot of confusion in the marketplace regarding electrified vehicles, hybrid technologies, and all of the related considerations such as HVAC, idle elimination, ePTO, V2G, and more.
Fortunately, our customers are beginning to understand that EDI’s innovation isn’t just about plug-in hybrids or electrifying vehicles - it’s about engineering some of the finest zero emissions, fully electric vehicles available in the market today. They operate in the city and on the highway with full electrical performance and don’t require engines to run HVAC, accessories, or tools. At the same time, they also include advanced features such as highly efficient parallel and series hybrid range extension options and high levels of synchronized AC power export and two-way charging.
The reason the differentiation of EDI’s approach is significant is that while there are many “plug-in hybrid” options in the market, many of those don’t address the “Zero Emissions Mission” and they may have substantial performance limitations such as: limited full electrical top speed, no zero emissions traction capability, only an electrical assist for launch, limited ePTO or idle elimination capability, etc.
In our work with visionary organizations like CARB and PG&E, we see their drive to arrive at a zero emissions transportation future which also aligns with EDI’s mission. In collaboration with our customers, EDI has already developed a variety of fully functional Zero Emissions capable vehicles with range extension options for highway and city buses, logistics trucks, utility worktrucks, SUVs, and sedans. We’ll be continuing that innovation going forward but always with a mission of providing drivetrains for superior, full functionality, zero emissions capable vehicles.

Track the Trucks
EDI’s utility work truck solution featured at Electric Vehicle Day
Efficient Drivetrains’s PHEV work truck solution created exclusively for PG&E was recently showcased as part of Electric Vehicle Day at the San Ramon Valley Conference Center on March 4th. The event featured current electrified models from a range of automotive manufacturers as part of PG&E’s efforts to encourage its employees to adopt electric vehicles and to promote the utility’s special EV rate plans and workplace electric vehicle charging station program.
EDI’s utility work truck solution is an industry-first plug-in hybrid electric Class 5 work truck with 120kW of exportable power. It is currently being used by PG&E to shorten or eliminate planned and unplanned power outages for up to 100 homes at a time and to reduce fuel costs and emissions. PG&E will deploy nine additional EDI trucks throughout its service area in Dixon, California and one in the Bay Area later this year.
A recent write up is available on the Transmission and Distribution World website.

EDI at the NTEA Green Truck Summit
To further Efficient Drivetrain’s mission of greening America’s fleets, Joerg Ferchau, CEO of EDI, served as a panelist at the Green Truck Summit sponsored by the Association for the Work Truck Industry (NTEA) on March 3rd. The Green Truck Summit is held in conjunction with The Work Truck Show, North America’s largest work truck event, and is the leading educational forum on how the green revolution impacts vocational trucks.
The panel focused on the fuel savings and benefits of the electrification of vehicle systems, truck-mounted equipment, and worksite operations. While experienced utility fleet managers shared the benefits of electrifying work trucks, Joerg brought a unique perspective, providing a look at the future of vehicle electrification.
“Using electrified vehicles diminishes fuel costs, significantly reduces emissions, and creates a quieter and safer workplace. It is my hope that this panel discussion at NTEA has inspired fleet owners to consider greening their vehicles,” commented Joerg Ferchau.
Bi-directional charging a possible game-changer in the EV world
By Alysha Webb, Contributing Author
Plug-in vehicles possess an ability that many of us wish we had – they can earn money while they are just sitting around. An electric car’s battery is storing energy when the car isn’t being driven. What if that battery could produce energy for the grid while stationary, as well as consuming it when being driven?
The concept of the car as a “Prosumer” isn’t new, but it hasn’t become a reality because of several obstacles. Those are beginning to come down, however.
One obstacle is that the way electricity is sold doesn’t lend itself to bi-directional charging, as the function of a vehicle both drawing and discharging electricity is known.
“The whole problem is there are not tariffs or market mechanisms to facilitate (bi-directional charging) further,” said Christine Hertzog, managing director at the Smart Grid Library, a consultancy focused on machine-to-machine transmission. “The EV tariffs we have are unidirectional.”
Some electric vehicles are already exporting power, but not selling it back to the grid. Trucks equipped with a plug-in electric vehicle drivetrain developed by Efficient Drivetrains (EDI) can generate up to 120 kilowatts of electricity. Trucks with that capability are being tested by PG&E, a utility in Northern California.
PG&E’s electrical grid is not buying the power from the EDI trucks, however. Rather, the utility sees it as backup power that can light up a neighborhood when it shuts down the grid to make repairs.
The social and business benefits of bi-directional charging would be enormous, said EDI founder and chief technical officer professor Andy Frank. "The issue is how to transition from the current ‘consumer’ business model to the ‘prosumer’ business model seamlessly with everyone jumping onboard the concept,” he said. The interesting thing, he added, is that some utilities are already buying electricity generated by their customers’ solar panels. But they haven’t made the leap to EVs.
Changing the equation
Bi-directional charging technology has already been proven to work. The University of Delaware, Delaware Power, and California-based EV Grid, California-based company, showed that with a fleet of BMW’s Mini-E EVs equipped with bi-directional charging. Under the “Grid on Wheels” program, the utility bought electricity from leasees of the Mini-E EVs .
The program never went past pilot stage, however. Tom Gage, founder and president of EV Grid, said the reluctance of automakers to produce and sell electric vehicles is one reason for the slow spread of bi-directional charging. That is changing, however. More plug-in electric consumer vehicle models are being launched, and sales are slowly rising.
A bigger problem is the electric utility business model, which is “not compatible” with the concept, said Gage. Widespread use of bi-directional charging requires “quite a few changes with the utilities and the automakers,” he said.
Some utilities are already working to make bi-directional charging a reality. SoCal Edison is taking part in a U.S. Department of Defense-funded project at Los Angeles Air Force base.
In the project, 32 electric vehicles will feed energy back into the grid in response to signals. When the grid tells the vehicles there is excess capacity, the EVs will ramp up their battery charging. SoCal Edison will bill the base for the retail service and pass any payments for the electricity on to the Department of Defense.
“There’s a convergence taking place between regulatory policy involving air quality and carbon emissions, and rapidly evolving battery technology,” said Lisa Cagnolatti, vice president of SoCal Edison’s business customer division in a press release. “Add the fact that customers are opting for greater fuel efficiency and cleaner fuel sources, and the stage is set for V2G.”
The electricity will start its bi-directional flow in this summer, and continue for one year. SoCal Edison will use the data to see if the electric vehicles can help reduce total costs for the fleet.
There is already some evidence it could. A Department of Defense study estimated the value of using bi-directional charging with an electric sedan to be $150 per month, while a different study put that benefit at $100 per month.
If either of those estimates is proven, it could be a big boost for electric vehicles, said the Smart Grid Library’s Hertzog. “What if your car is an asset that can actually earn money for you?” she said. “That is quite a change in the equation.”
