With global demand for battery minerals continuing to rise, tech giants ABB, Hitachi, Komatsu, and Sumitomo are working together, developing a clever tech strategy that’s slashed emissions across Japanese mining operations.

The collaboration between Hitachi Construction Machinery and ABB Traction to build a massive, fully electric 240 ton haul truck for extreme duty mining operations reached a critical stage last year, with the completion of their first prototype in February. Over the last year, Komatsu and Sumitomo have signed on as well, and the new haul trucks are doing their thing at the Kansanshi copper-gold mine in Zambia.

“We are delighted to see our collaboration with Hitachi Construction Machinery reaching this crucial step,” Fabiana Cavalcante, Head of Mobile e-Power, ABB Traction, explained last year. “The project is not only helping to tackle the issues involved in dump truck electrification but is also contributing to enabling a low-carbon world through the reduction of greenhouse gas emissions. We look forward to seeing the prototype prove its capability in the Zambian copper-gold mine.”

The deployment at Kansanshi marks the first OEM-led pilot program of this type of electric vehicle in real-world mining conditions.

And, as for what type of electric vehicle is “this” type of electric vehicle – that was a big topic of conversation at The Electric Mine Conference in Chile last week, where ABB, Hitachi, Komatsu, and Sumitomo discussed not just Hitach’s electrification of FQM’s heavy haul trucks, but also the “trolley-style” overhead charging system that enables the trucks to operate around the clock, without the need to stop for charging.

On level ground, the truck’s electric powertrain draws power from its high-capacity battery. During power-intensive uphill climbs, the truck connects to the overhead wires and draws additional power, minimizing the demands on the battery. On downhill runs, the trucks recharge with regenerative braking.

The mine’s clever three-part system greatly reduces (if not outright eliminates) any downtime associated with charging, and enables the truck to operate almost continuously.

Electrek’s Take


HITACHI CONSTRUCTION MACHINERY COMPLETES PROTOTYPE FULLY ELECTRIC DUMP TRUCK BASED ON ABB’S INNOVATIVE BATTERY TECHNOLOGY

The International Energy Agency (IEA, a Paris-based, 31 nation organization established in 1974 that provides policy recommendations, analysis and data on the global energy sector) projects that mineral demand from EVs will see 30x growth between 2020 and 2040, with demand for lithium and nickel growing 40x as demand for diesel is dropping faster than most people predicted, reaching a 26-year low last summer.

The IEA’s projections take several battery development scenarios into considerationand include increasingly familiar terms like utility-scale battery energy storage. All of which is to say: we’re gonna be mining a whole lot more, for a whole lot longer – and decarbonizing those operations is critical to doing all this properly.

The current plan is to convert Hitachi’s fleet of 2500 HP EH4000 240-ton diesel mining trucks to electric driveYou can learn more about the ABB eMine process in the company’s conceptual (read: it’s all CGI) launch video from last year, below, then let us know what you think of the group’s collaboration in the comments.

China’s nationwide ‘cash for clunkers’ trade-in program causing huge e-bike boom

China's nationwide 'cash for clunkers' trade-in program causing huge e-bike boom

While much of the Western world is still figuring out how to get more people on electric bikes, China just flipped a switch, and the results are staggering. Thanks to a generous nationwide trade-in program rolled out around six months ago, China has seen an explosive surge in electric bicycle sales, with over 8.47 million new e-bikes hitting the road in the first half of 2025 alone.

The program, which offers subsidies to riders who trade in their old, often outdated electric bikes for newer, safer, and more efficient models, has sparked a new e-bike sale boom in a country already dominated by e-bike travel. In major provinces like Jiangsu, Hebei, and Zhejiang, over one million new e-bikes were sold in each region in just six months. That’s a tidal wave of e-bike sales.

The incentives vary depending on location and the model being traded in, but for many consumers, the subsidies cover a substantial portion of a new e-bike’s price – enough to turn a “maybe next year” purchase into a “right now” upgrade. And these aren’t just budget bikes either. The program has driven demand for higher-quality models with better batteries, safer braking systems, and more reliable electronics, accelerating both adoption and innovation across the industry.

The move has proven successful in replacing the millions of older models with lower-quality lithium-ion batteries that had posed safety risks around the country. Instead, China has pushed for higher-quality lithium-ion batteries, a return to a newer generation of higher-performance AGM batteries, and even interesting new sodium-ion battery options.

Most e-bikes in China look more like what we’d consider seated scooters

According to China’s Ministry of Commerce, more than 8.4 million consumers have participated in the e-bike trade-in program so far, contributing to a sales increase of 643.5% year-over-year and more than doubling sales month-over-month. Meanwhile, production of new electric bicycles rose by nearly 28%, as manufacturers scrambled to meet demand. The sales boosts have already been seen in the financial reports of major industry players like NIU.

And it’s not just the big players benefiting – over 82,000 small independent e-bike dealers reported average sales increases of ¥302,000 (around US $42,000), giving a serious boost to local economies.

What’s particularly striking here is how fast this happened. The program was officially launched late last year as part of a broader effort to stimulate domestic consumption and phase out outdated vehicles and appliances. But while most analysts expected gradual growth, the e-bike sector responded much more quickly. In less than a year, the trade-in subsidies have reshaped the electric bicycle market, creating a consumer-driven boom that shows no signs of slowing.

For those of us watching from outside China, it’s hard not to wonder what might happen if other countries tried something similar. While most families in Chinese cities already own an electric bike and thus see this as an opportunity to trade it in for a newer model, Western countries like the US are still figuring out how to stimulate commuters into buying their first e-bike.

It’s too soon to know exactly how long the boom will last or whether the momentum will carry into 2026 and beyond. We’ve seen bicycle industry bubbles grow and burst before. But one thing’s clear: with the right incentives, even modest ones, it’s possible to ignite real, large-scale change. China just proved it with nearly 8.5 million new e-bikes to show for it.

And if you’re wondering what it looks like when a country takes electric micromobility seriously, this is it.

Day 1 of the Electrek Formula Sun Grand Prix 2025 [Gallery]

Day 1 of the Electrek Formula Sun Grand Prix 2025 [Gallery]

Today was the official start of racing at the Electrek Formula Sun Grand Prix 2025! There was a tremendous energy (and heat) on the ground at NCM Motorsports Park as nearly a dozen teams took to the track. Currently, as of writing, Stanford is ranked #1 in the SOV (Single-Occupant Vehicle) class with 68 registered laps. However, the fastest lap so far belongs to UC Berkeley, which clocked a 4:45 on the 3.15-mile track. That’s an average speed of just under 40 mph on nothing but solar energy. Not bad!

In the MOV (Multi-Occupant Vehicle) class, Polytechnique Montréal is narrowly ahead of Appalachian State by just 4 laps. At last year’s formula sun race, Polytechnique Montréal took first place overall in this class, and the team hopes to repeat that success. It’s still too early for prediction though, and anything can happen between now and the final day of racing on Saturday.

Congrats to the teams that made it on track today. We look forward to seeing even more out there tomorrow. In the meantime, here are some shots from today via the event’s wonderful photographer Cora Kennedy.

Stay tuned for more!
