New Goulburn battery beats grid upgrade for electric vehicle ultra rapid charging

Australian fast charging company ChargeFox has installed a sizeable battery installation in Goulburn to support its new ultra-rapid electric vehicle charger, as well as earning income from providing frequency services to the grid, and saving money by avoiding a grid upgrade.

The 250kW/273kWh battery, using LG-Chem cells and Vacon inverters, has been designed and installed by PowerTec, and is the second time that ChargeFox has chosen a battery as a cheaper alternative to upgrading the permanent power supply at a charging site.

“In Goulburn we have a 180kW connection to the grid, which powers about 30kW of constant load at the service station, leaving 150kW for the chargers. We’ve installed 750kW of Tritium chargers there, with about 50kW of solar coming,” says Evan Beaver, head of charging at ChargeFox.

“The battery is 250kW/273kWh, and monitors the grid supply, the petrol station load and the charger demand and lops the demand peaks. Using the battery in this primary function is cost effective against a 500kW grid connection upgrade and worth doing on its own. Adding solar to this mix lowers the cost of charging the battery.”

Beaver says the battery can operate for about one hour at full power, but has the ability to change power quickly and respond automatically to grid disturbances, That makes it perfect for the FCAS market, which it will offer as a secondary function.

“So using  a battery in Goulburn has reduced our installation costs, reduced charging site electrical costs, increased the use of renewables and improved grid stability,” Beaver says. “The costs are a touch high to use them everywhere right now, but I can see batteries getting used in this way more and more in coming years.”

PowerTec managing director Michael Reiner Jansen said in a LinkedIn post that the battery primarily serves as an EV charging buffer, allowing for ultra-fast charging despit the weak grid connection, FCAS services, and back-up power for the site.

NJ Drivers Can’t Claim $5,000 Electric Vehicle Rebate Just Yet. Here’s Why

Credit: Karlis Dambrans/Flickr
Gov. Phil Murphy vouched that the rebate would apply to all electric-vehicle purchases or leases dating back to Jan. 17, the day he signed the program into law.

Eric Fierro had been itching to buy an electric vehicle for years. So when New Jersey launched a generous $5,000 rebate program on the cars this month, the teacher and coach at Southern Regional High School was fired up.

“Boom! It’s like, this is what you’ve been waiting for, coach. Let’s go!” he said.

When he went to a local dealership, though, the employees there were confused. First, they told him the program wasn’t up and running yet. Then, they said it was, but he’d have to figure out how to get the money himself.

Originally looking to buy, Fierro settled on leasing a 2019 Chevy Bolt to limit his financial exposure should the rebate fall through.

“I’m anticipating there being a chance that this doesn’t happen,” he said. “I’m hoping that it does. I’m about 50-50 right now, I’d say, that I get the $5,000.”

The problem is that Gov. Phil Murphy trumpeted the rebate program before the state Board of Public Utilities had time to set up how it would work. Asked to clarify the situation on his monthly call-in radio show, Murphy vouched that the rebate would apply to all electric-vehicle purchases or leases dating back to Jan. 17, the day he signed the program into law.

“The rebates will become available in spring, but they’ll be retroactive to any purchases since I signed the bill,” Murphy said. “That will be a mail-in process, so you’ll get the check by mail. Beginning in the summer — I don’t have a specific date — it will be what they call cash on the hood, meaning it’ll be a rebate literally at the point of sale.”

Still in the works

For now, those interested in driving a new electric vehicle will have to take the governor at his word. Asked to confirm the details, a spokesperson for the Board of Public Utilities said they are still in the works.

“Board staff is in the process of developing the program along with the program manager, Center for Sustainable Energy,” said spokesperson Peter Peretzman. “It will then be presented to the Board for consideration and potential approval.”

According to the new law, the rebate will apply to vehicles with a retail price below $55,000 that are registered in New Jersey. How big a credit drivers get will depend on how far their vehicle can travel on a single charge. The state will offer $25 for each mile the car runs on electric power instead of gas, up to a $5,000 cap.

That means cars with 200 miles of electric range or more — such as those offered by Tesla, Chevrolet, Nissan and several other carmakers — would qualify for the maximum amount.

Plug-in hybrid cars are also eligible for the rebate through 2022, although with a median electric-only range of


Ford, Lincoln Cancel Rivian-Powered Electric Vehicle

Ford and its luxury brand Lincoln have canceled an all-electric SUV that was going to be powered by technology provided by EV startup Rivian, the companies told Automotive News on Tuesday. The Verge reports: Lincoln says it is still working closely with Rivian, including an “alternative vehicle” that will also be based on Rivian’s electric vehicle skateboard platform. “Given the current environment, Lincoln and Rivian have decided not to pursue the development of a fully electric vehicle based on Rivian’s skateboard platform. Our strategic commitment to Lincoln, Rivian and electrification remains unchanged and Lincoln’s future plans will include an all-electric vehicle,” a spokesperson from Lincoln told The Verge in a statement.

Lincoln declined to say what specifically about the pandemic led to the cancellation. “This was a decision that was mutually made by Lincoln and Rivian given the rapidly changing environment and after a review of product plans,” the spokesperson said. “As we moved through the development cycle, we determined that it would be better to pivot from the Rivian’s skateboard platform and focus our development efforts on Lincoln’s own fully-electric vehicle.” This is a pretty big blow, considering Ford invested $500 million in Rivian last year, just two months after Amazon led a $700 million investment in the Michigan-based startup.

CNBC reports that Ford “lost $632 million during the first quarter and warned investors that it expects an adjusted pretax loss of $5 billion during the second quarter as the company grapples with the fallout from the coronavirus pandemic that’s shuttered factories and devastated sales.”

State Electric Bicycle Laws | A Legislative Primer


women with purse and electric bikeThe past few years have seen a marked increase in the number of electric bicycles (or “e-bikes”) in the U.S.

This primer deals specifically with low-speed electric bicycles as defined by the Consumer Product Safety Commission. E-bikes are most frequently “pedal-assist” or “muscle-assist,” meaning the rider must be pedaling for the electric motor to engage. E-bikes may also come equipped with a throttle that allows the bike to be propelled without pedaling.

The bicycle’s low-speed electric motor provides a boost of power to climb hills, extend the range of trips where a bicycle can be used, allow current bicycle users to bike more often and farther, provide a new recreation option for people who want to bike and in general, extend the range of any ride.

Low-speed e-bikes are as safe and sturdy as traditional bicycles and move at speeds similar to conventional bikes. E-bikes are emissions-free, low impact and operate silently. E-bikes vary widely in terms of shape and size, but the different types closely align with those of regular bicycles. E-bikes resemble traditional bicycles in both appearance and operation and do not function similarly to mopeds, scooters and other motorized vehicles.

According to a 2018 bicycle industry analysis, e-bikes sales increased 83 percent between May of 2017 and May of 2018, and e-bikes made up 10 percent of overall bikes sales in the U.S. for that time period. While the Asian and European e-bike markets are more robust, industry advocates hope to continue to expand U.S. e-bike sales.. Most major U.S. bicycle brands sell e-bikes, and bicycle manufacturers have moved or are positioning themselves to move to the U.S. to capitalize on the growing market.

Electric bicycles cost on average $2,000 – $3,000, versus a $1,000 average investment for a mid-range traditional commuter bicycle. An investment in an electric bicycle is appealing to those who are looking to replace short trips typically made by car, therefore the investment can be justified if the buyer factors in the reduced cost of car maintenance and fuel.  

Reasons for purchasing an e-bike vary, with some looking for a cheap commuting mode and others looking for a less physically demanding bicycle option or help bicycling through hilly areas. E-bikes may also provide a more attractive and feasible choice to take short trips. According to U.S. Department of Transportation survey data, half of all trips in the U.S. are three miles or less in length, a distance widely regarded as bikeable for most adults and even more feasible for electric bicycle riders. Seventy-two percent of those trips are currently made by cars and fewer than 2 percent by bicycle. E-bikes also provide a new transportation and recreation option for people with disabilities and those with physical limitations.

E-bikes have even been embraced by the nation’s rapidly expanding bike-share systems. In 2011, the University of Tennessee-Knoxville launched the country’s first electric bicycle sharing system, with two bike-share stations on their campus. In 2015, Birmingham, Ala., unveiled a citywide bike-share
