HOLMS develops self-powered attachments for electric equipment fleets
HOLMS Attachments has made it easier for heavy equipment fleets to electrify with a new sweeper attachment that’s equipped with its own power source, freeing it from the need for a mechanical or battery (e) PTO.
Commercial trucks do more than just move people and things from place to place – special implements like street sweepers, cherry pickers, and tow beds mean they do real work, as well. But the attachments, implements, and even utility bodies being upfitted onto these trucks were largely developed for diesel platforms. They typically get juice from hydraulics or other power take-off (PTO) systems that typically take the form of a splined drive shaft powered directly by the ICE.
BEVs work differently, and have to draw on their battery power to operate these tools. That takes away which takes away from both the range and performance of the EVs in question. Adding to the complexity, some of these attachments are still mechanically driven, requiring an electrically-driven spline shaft, or “ePTO” to operate.
The new eSL Electric Sweeper attachment from HOLMS aims to solve for all that new complexity that’s emerging as electric equipment becomes more commonplace.
“Electric equipment in general has taken a lot of different directions,” said Dan Snedecor, President and General Manager of HOLMS Attachments. “We realized, let’s not use the power from the machine, because keeping up with that will be even harder than keeping up with the different style hooks and hydraulic systems.”
Developed for the electric equipment needs of the near future, HOLMS’ eSL optimizes the uptime of your electric vehicle or equipment asset so you can complete more tasks between charging sessions.
“Our theory is this will be kind of like an electric drill that we all have at home, where you leave it plugged in until you need it. You go out, you use it, and then you put it back on the charger when you’re done,” Snedecor told Equipment Journal. “The real benefit of that will be the end users don’t need machines that have extra hydraulic functions necessarily.”
The prototype sweeper is controlled from the cab of the wheel loader via Bluetooth and is equipped with a 10 kWh, 48V li-ion battery pack that’s good for three-and-a-half hours of runtime on a single charge. HOLMS says the sweeper’s battery can be recharged in about 90 minutes.
Electrek’s Take
Bobcat was arguably the first big equipment company to start rethinking the way implements would work on electric machinery that didn’t have a reciprocating engine at its core, but the replacement of hydraulics and PTOs with servos and gears seems to be well under way.
We’re here for it.

Tesla has inked its first deal to build a grid-scale battery power plant in China amid a strained trading relationship between Beijing and Washington.
The U.S. company posted on the Chinese social media service Weibo that the project would be the largest of its kind in China when completed.
Utility-scale battery energy storage systems help electricity grids keep supply and demand in balance. They are increasingly needed to bridge the supply-demand mismatch caused by intermittent energy sources such as solar and wind.
Chinese media outlet Yicai first reported that the deal, worth 4 billion yuan ($556 million), had been signed by Tesla, the local government of Shanghai and financing firm China Kangfu International Leasing, according to the Reuters news agency.
Tesla said its battery factory in Shanghai had produced more than 100 Megapacks — the battery designed for utility-scale deployment — in the first quarter of this year. One Megapack can provide up to 1 megawatt of power for four hours.
“The grid-side energy storage power station is a ‘smart regulator’ for urban electricity, which can flexibly adjust grid resources,” Tesla said on Weibo, according to a Google translation.
This would “effectively solve the pressure of urban power supply and ensure the safe, stable and efficient electricity demand of the city,” it added. “After completion, this project is expected to become the largest grid-side energy storage project in China.”
According to the company’s website, each Megapack retails for just under $1 million in the U.S. Pricing for China was unavailable.
The deal is significant for Tesla, as China’s CATL and carmaker BYD compete with similar products. The two Chinese companies have made significant inroads in battery development and manufacturing, with the former holding about 40% of the global market share.
CATL was also expected to supply battery cells and packs that are used in Tesla’s Megapacks, according to a Reuters news source.
Tesla’s deal with a Chinese local authority is also significant as it comes after U.S. President Donald Trump slapped tariffs on imports from China, straining the geopolitical relationship between the world’s two largest economies.
Tesla Chief Executive Elon Musk was also a close ally of President Trump during the initial stages of the trade war, further complicating the business outlook for U.S. automakers in China.
The demand for grid-scale battery installation, however, is significant in China. In May last year, Beijing set a new target to add nearly 5 gigawatts of battery-powered electricity supply by the end of 2025, bringing the total capacity to 40 gigawatts.
Tesla has also been exporting its Megapacks to Europe and Asia from its Shanghai plant to meet global demand.
Capacity for global battery energy storage systems rose 42 gigawatts in 2023, nearly doubling the total increase in capacity observed in the previous year, according to the International Energy Agency.

BYD is testing solid-state EV batteries in its Seal sedan with nearly 1,200 miles of range
BYD has now begun testing solid-state EV batteries in its Tesla Model 3-rivalling Seal. Initial tests suggest that the total driving range could reach nearly 1,200 miles (1,875 km).
BYD begins testing solid-state EV batteries in the Seal
It has been over a decade since BYD first began researching and developing the promising new EV battery technology.
Last year, the company reached a milestone by testing its first solid-state battery cells with capacities of 20 Ah and 60 Ah. We knew BYD was planning to launch its first vehicles powered by the new batteries in 2027 after Sun Huajun, the CTO of BYD’s battery business, confirmed the timeline earlier this year.
At the 2025 China All-Solid-State Battery Innovation and Development Summit, Sun stated that BYD has officially installed solid-state batteries in its popular Seal EV and is now testing them on roads.
Once testing is finalized, which is expected to occur in 2027, BYD plans to begin installing solid-state batteries in its production vehicles.
Between 2027 and 2029, production will be limited during the first two years. However, in 2030, BYD plans to begin mass production. BYD has previously said that by the end of the decade, it expects “liquid and solid to be the same price.” In other words, solid-state batteries will be about the same cost as current liquid lithium-ion batteries.
The Seal, BYD’s Tesla Model 3-rivalling electric sedan, is expected to be the first EV available with solid-state batteries, starting in 2027. Other models will begin to hit the market in 2028 and the following years.
BYD’s solid-state batteries have an energy density of 400 Wh/kg, or nearly twice that of current lithium-ion batteries.
According to local reports, BYD’s solid-state EV batteries set a record by gaining 1,500 km (932 miles) range in just 12 minutes of charging.
The test charged the battery to just 80%, meaning total EV range could reach upwards of 1,875 km (1,165 miles). Keep in mind, that is CLTC range. On the EPA scale, it would be closer to 1,300 km (808 miles), which is still way more than enough.
BYD’s Seal currently starts at just 175,800 yuan in China, or about $25,000. When it initially hits the market in 2027 with solid-state batteries, the Seal will likely be priced higher.
Electrek’s Take
BYD is already dominating the global EV market. It just surpassed Tesla in Europe and the UK in monthly registrations for the first time, and this could be just the start.
With several new batteries and plenty of other EV technologies, including ultra-fast chargers, smart driving features, and advanced new platforms, BYD is laying the groundwork for more growth over the next few years.
Not only that, BYD is already known for its low-cost cars like the Seagull (Dolping Surf in Europe), priced under $10,000 in China. The new tech is expected to unlock longer driving range, faster charging, and lower costs.
BYD will compete with CATL, Mercedes-Benz, Volkswagen, Stellantis, Nissan, and several others that are also aiming to launch their first EVs with solid-state batteries around 2027 or 2028. Nissan’s director of product planning in Europe, Christop Ambland, confirmed the company’s timeline this week with Auto Express, saying, “We will be ready for SSB (solid-state batteries) in 2028.”
