Range Energy announces two partners to electrify refrigerated trailers
Range Energy, a company which builds large-battery electric trailers to help fleets electrify at the drop of a hat, has announced partnerships with Thermo King and ESL Power Systems to bring its technology to refrigerated trailer units.
The idea behind Range’s product is that it adds a battery and an electric motor e-axle to a semi truck trailer, instead of to the tractor itself, which means that a fleet can add electric capabilities without having to buy new tractors. This means the fleet can effectively hybridize its operation without having to buy new tractors.
While this isn’t a fully electric solution, it can still reduce fuel usage by a large amount (independent tests say 36%), and adds new capabilities to a truck – like better control over the trailer and regenerative braking to avoid brake fade.
We met Range at ACT Expo in Anaheim two years ago, where they gave us one of the coolest demos we’ve seen. Just by attaching to a tractor’s kingpin, the system can decide how much power to apply and offers extremely natural feeling movement, making a heavy trailer feel light as a feather:
Range isn’t quite up to production yet, but they have done some trials. In addition to the independent testing above, Range trialed its technology with Petaluma Egg Farm, up in Northern California, where it says the company saw a 50-70% improvement in MPG for the trucks using Range’s electric trailer.
But the company is still working to find novel applications for its technology, and when we caught up with them at ACT Expo this week, they wanted to focus on how Range trailers could be used for refrigerated freight in order to cut emissions and reduce the need for a separate engine to run the reefer unit.
In service of this, it has partnered with two companies in the refrigeration space – Thermo King, the biggest name in electrified trucks, and ESL Power Systems, a company that manufactures shore power solutions for heavy industry.
Range said Thermo King came to them because they’re the only company with enough energy storage to be able to run a refrigerated unit for an extended period of time. While there are other companies doing electrified refrigerated trailers, Range’s trailer has a much larger 288kWh battery (since it also works as a traction battery for the trailer’s electric motor).
This means it has a lot more energy on board to run a refrigeration unit, which can draw ~5-20kW depending on several factors. Range told us that fleets have told them this would be enough energy to keep the trailer box cold for a full day while unplugged from shore power, even in hot temperatures.
And that’s a big deal, because heretofore, refrigerated units have mostly run with an additional small diesel engine. Removing that engine means less pollution, less diesel usage, more noise, less maintenance, and it also means the refrigerated unit could operate in more environments (for example, you don’t want a running engine indoors if you can avoid it – but an electric unit doesn’t have to deal with that).
Speaking of shore power, that’s what Range is working with ESL to implement. ESL creates small, modular shore power systems which are easier to install, helping fleets save on infrastructure upgrade costs. Their boxes can deliver high-powered 480V 3-phase AC charging.
Plugging into one of these would allow the Range Energy trailer to charge at up to 50kW or so, meaning a 5-6 hour charge time for the 288kWh battery.
Range has already trialed its partnership with Thermo King, in the Petaluma Egg Farm example given above. Although the ESL partnership is newer, and those will be trialed soon.
Range is targeting the end of this year, or possibly the start of next year, for its first customer deliveries.

Tesla has opened orders for the Model Y Long Range RWD for $45,000 in the US. It’s the new entry-level Model Y following the design refresh earlier this year.
Since launching the updated Model Y earlier this year, Tesla has only offered the best-selling electric SUV in a single Long-Range AWD configuration.
First, it was as a fully-loaded $60,000 Launch Edition, and last month, it started deliveries of the regular Model Y AWD starting at $49,000.
As we recently noted, Tesla didn’t have much of an order backlog for the new Model Y in the US, and it has already started gathering new Model Y AWD in inventory just weeks after launching the vehicle.
Tesla even started offering subsidized financing rates on the new SUV this weekend.
Now, the automaker is starting to take orders for the new Model Y Long Range RWD
The new trim starts at $44,990 and enables 357 miles of range – an extra 30 miles over the AWD version.
However, due to its single motor powertrain, the lower-priced version is slightly slower with a 0-60 mph acceleration in 5.4 seconds rather than 4.6 seconds.
The automaker says that deliveries of the new version will start in the US in the next 3 to 5 weeks. It launched the new Model Y RWD in Europe weeks ago.
Tesla also offers a Standard Range RWD in Europe and China for even cheaper, and deliveries have already started in China.
Electrek’s Take
Tesla appears to have waited to open orders for the Model Y RWD in the US to optimize demand for the Long Range AWD.
But now it needs a cheaper model to sustain demand at the current production rate.
In the coming weeks, it will start building a mix of RWD and AWD in Fremont and Austin to
Interestingly, Tesla currently only offers the subsidized 1.99% financing rate on the Model Y Long Range AWD. I would assume that Tesla plans to take advantage of the boost in demand that the cheaper model will create.
However, US buyers probably won’t have to wait more than a few weeks before Tesla starts to offer lower interest rates on all versions, like it already does in Europe and China.

![Big Mack, hydrogen Honda, and a ride in the Tesla Semi at ACT Expo 2025 [part 6]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/05/act-2025.jpg?resize=1200,628&quality=82&strip=all&ssl=1)
On today’s thrilling episode of Quick Charge, we’ve got some of the highlights of the 2025 ACT Expo, including the all-electric Windrose and Mack Pioneer Class 8s trucks, a hydrogen fuel sell [sic] from Honda, a fun charging surprise, and – after an eight year wait – we finally get a ride in the all-new (in 2017) Tesla Semi!
ACT Expo is North America’s premier clean truck and transport trade show – and for 2025 it was bigger than ever, with more exhibitors and more, more capable battery electric vehicles than ever. The downsides? NACFE have scored with their “messy middle” messaging, and the return of “clean diesel” talking points. We’ve got a brief rundown and links to all the details, below.

Abundance Energy, sonnen, and Energywell are teaming up to bring smarter, more resilient energy to Texas homes through a huge new virtual power plant (VPP) initiative.
By combining behind-the-meter home batteries, solar power, and advanced energy software, the trio is building a network of connected homes that can work together to support the grid. Customers who install sonnenConnect home batteries through Abundance Energy will now be part of a system that automatically stores and shares power when it’s needed most. That means lower electricity bills, better reliability during extreme weather, and a cleaner energy mix overall.
The VPP will cover all of ERCOT, with the primary focus in the greater Dallas-Fort Worth and Houston areas. Each home will have two 4.8kW/20kWh sonnenCore+20 battery units. The current customer base that will be enrolled in the VPP equals 60 MWh, and this will continue to grow each month. The VPP is already on track to replace Tesla as the largest virtual power plant in Texas by the end of 2026.
Here’s how it works: The batteries are continuously managed using Energywell’s Proton platform and sonnen’s smart VPP technology. This system monitors solar generation, customer energy use, and real-time electricity prices, and then decides when to charge or discharge each battery. Instead of just sitting idle, these batteries turn into mini power plants that can react to grid needs in real time.
And when thousands of batteries work together, they form a virtual power plant—a decentralized network that reduces the strain on the grid, especially during peak demand or power outages. Unlike traditional power plants, VPPs don’t burn fossil fuels. They use clean, stored electricity from homes and businesses, helping cut carbon emissions while keeping the lights on.
“Our mission is to empower homeowners with smarter, more sustainable energy solutions,” said Thomas Mandry, CEO of Abundance Energy. “This partnership delivers a new kind of VPP model that benefits customers and strengthens the Texas grid.”
Blake Richetta, CEO of sonnen, added, “With Abundance Energy and Energywell, we’re showing how everyday homeowners can become part of the solution to Texas’ energy challenges.”
As Texas continues to face grid reliability issues, especially in extreme heat or cold, this kind of flexible, customer-powered energy system will make homes more resilient and give customers more control over their power.
