Green Orchards
Many carmakers are pledging to go all-electric in the near future, so other forms of hard working machinery are starting to follow suit…including down on the farm where Green Acres is truly the place to be.
Although farm tractors and the jobs they do have become more sophisticated and high-tech over the years, the heavy chassis and engines under the hood haven't always kept pace with that progress and most still rely primarily on diesel fuel.
Hummingbird EV is one company looking to upset that status quo apple cart. They’ve teamed up with the San Joaquin Valley Clean Cities Coalition, Project Clean Air, and others to place four prototype zero-emission electric tractors in service at one of the country’s largest fruit growers.
These EV tractors are fitted with 120 peak kilowatt electric motors tied to Hummingbird controllers and software. With 25 kilowatt-hour battery packs and 65 horsepower, performance is equivalent to a gas or diesel tractor of the same size.
Moonlight companies, in Reedley, California, is an ideal test bed. They operate year-round, growing all varieties of citrus and stone fruits...from peaches, plums, and pomegranates.. to grapes, lemons, oranges and -- during our visit, lots and lots of mandarins -- and shipping them fresh to markets all over the globe.
This third-generation farm is committed to using environmentally-sound practices and investing in the latest technology. They even have a 2-megawatt on-site solar farm which powers much of their packing and cold-storage operations. So trying out these EV tractors for the past year was an easy call.
TY TAVLAN: We use approximately 80 small diesel-powered tractors during the harvest season to pull our fruit through the field. For this particular function, since it pulls fruit, and then it stops..then it pulls fruit again and then it stops, we can get approximately two days worth of work out of the tractor.
What we really like about it is, it’s basically maintenance-free, it starts every time, and it works just fine.
JOHN DAVIS: The battery-electric tractors in this test are paired with an all-electric class 6 vehicle-to-vehicle charging truck, also designed by Hummingbird. It can provide up to 40 kilowatts of level 2 AC charging, enough to juice up two tractors simultaneously, eliminating time-consuming round-trips back to the charging station; a big advantage, especially during harvest. The truck itself has an 88 kilowatt-hour battery pack and 90 miles of range.
Hummingbird’s expertise is designing and scaling electric powertrains for medium duty applications like mining, utilities and food delivery. And they are challenging the notion that one size fits all down on the farm.
RAKESH KONERU: Every tractor has a certain demand in terms of the battery pack size and things like that..how long they use, how long they drive, so on and so forth, so where we’re unique is we’re trying to adapt where the commonality of parts come into play. So, when you try to scale it up, it’s easy to mix and match a production line with different scale of vehicles with the same system.
JOHN DAVIS: Like any farm in America, economics comes into play here too. Drought conditions in California and elsewhere have forced growers to cultivate fewer acres to conserve water, meaning tighter crop density is the key to making ends meet. So tractors of the future may need to hug the ground to fit under closely-planted trees, or be extra skinny to drive between them.
RAKESH KONERU: The main idea for us was to showcase the capability of what an electrification can bring into farming, but at the same time we’re also exploring the idea of what it takes for the farmer to be ready for future farming.
And every farm has a different, unique, requirement. If you go to a vineyard, for example, their needs are completely different, so when we see the market expansion, we want to explore the idea of, let’s design a chassis from the ground level up, which is well thought out you know, which can stick on for the next generations.
JOHN DAVIS: This type of custom design is well-suited for the flexible packaging afforded by electric battery packs. So it looks the E-volution of modern farming in the near future may well be fueled by the EV revolution of today.
EV Sales
The headlines are everywhere: electric vehicle sales are down! Dealers are swamped with unsold EVs! Car companies are doubling down on internal-combustion engines! The EV era is over before it began! And so on…
You know, there’s a lot of misinformation swirling around these days about the state of the current EV market. So, what are the facts and where might EVs go from here?
We’re in the midst of the most revolutionary shake up of the automotive market since the car replaced the horse as our preferred form of personal transportation back in the early 1900s. Then, as now, drivers faced the same decision of choosing petrol or electric power for their cars, and carmakers offered both options.
As it turned out, the rapid expansion of our interstate road system outpaced the electrification of rural America, paving the way for petroleum to take the lead in widespread availability, and to largely squeeze electrics out of the car market. Fast forward a hundred years: America is now wired from coast to coast, and advances in battery technology have made it possible for electric vehicles to perform competitively with gas and diesel models.
But more importantly, environmental concerns have become an important factor in determining our fuel of choice, fostering the second coming of the electric vehicle.
Now EV sales, including both plug-in hybrids and pure battery electrics, are surging beyond the early adopter and novelty stage, rising 46.5% in 2022 and 53.8% in 2023, achieving a record 9% of the total car market last year. After such rapid growth, some moderation was expected, but are EV sales really falling as headlines proclaim?
The short answer is no. While growth has slowed, plug-in vehicles still grew 17% in the first quarter of 2024, increasing their market share further as overall car sales rose only 5%.
JOHN O’DONNELL: “There’s a lot of articles and media suggesting that we’ve already reached a plateau for EV sales, and that’s false, that’s incorrect. The rate of adoption is slowing, but it’s still increasing nationwide. State by state, it varies.The coasts, east and west coasts, have the higher penetration. The center of the country is adopting at a more slow rate, but make no mistake, this is not going away simply because somebody wrote an article.”
Another trend we’ve noticed is that consumers’ preferred type of EV is shifting. For all of 2023, about 80% of EVs sold were pure battery electric. But plug-in gasoline-electric hybrid sales are growing, and currently make up a quarter of total EV sales.
When faced with the EV market’s three-headed conundrum: limited number of affordable battery electric choices, fear of range anxiety, and a public charging infrastructure that’s still a work in progress, many buyers see plug in hybrids as a safe near-term bridge to eventually going all-electric. And that shift is now forecast to widen for the foreseeable future, as manufacturers release more new PHEVs into the market.
JOHN O’DONNELL: “Consumer affordability is always on our minds, representing the people who sell the cars, but it’s also on the mind of the state, local and federal governments. They know that they need to help us balance the amount of technology, which costs money through research and development, and what the average consumer can afford.”
The good news for consumers is that EV prices are already coming down, and, with dozens of new electric vehicles of all types expected to enter the market over the next 18 months, there is little doubt that such increased competition will cause EV prices to moderate even further. Thus, most market experts are still conservatively predicting EVs to pass the 12% market share point for all of 2024, and 15%, or over 2 million new EVs on the road, in 2025.
Add to that continuing improvements in driving range and charging infrastructure, and the future of EVs in America is still quite bright. American consumers are smart enough to question the naysayers. They know that the time is finally right for the electric automobile to come into its own. It’s not only the best thing for the environment, it just makes good driving sense.
