As we trend toward more renewables and distributed energy resources (DERs), the design of the electric distribution system itself imposes physical limitations. These system constraints could lead to issues like overloaded power lines and faults that propagate freely.

But what if we could restructure the underlying system to support greater renewable integration and system resilience? To that end, a National Renewable Energy Laboratory (NREL)–led project is working on a new type of grid device enabled by silicon carbide (SiC) switches and other medium voltage (MV) power electronics that could segment sections of the grid, providing advanced control for flexibility and resilience for our power systems.

The project team is first designing a megawatt-scale prototype converter that provides native “back-to-back” conversion — AC to AC power — at distribution voltages (i.e., not requiring transformers to step down voltage to levels typically used in electronic power conversion). By using MV SiC-based power modules, the converters could be 1/5th the size and 1/10th the weight of alternate equivalent systems, which are trailer-sized and include heavy transformers. Then the team will connect the power converter into NREL’s MV testbed to validate new grid control approaches that the prototype enables.

The project is named “Grid Application Development, Testbed, and Analysis for MV SiC (GADTAMS)” and is funded by the Department of Energy’s Advanced Manufacturing Office.

The NREL-led GADTAMS project is developing and demonstrating smaller and lighter alternatives for direct medium-voltage connections on the grid, which could enable new resilient grid architectures.

“With back-to-back converters between feeders, we can go one step higher in providing resilience across the distribution system,” said Akanksha Singh, a project lead at NREL.

“This technology wasn’t necessary before because we didn’t have so many distributed energy resources on the system, but now we have feeders that are becoming saturated with PV; apart from storage, these feeders don’t have anywhere to inject that excess power,” Singh said. “A new approach to grid interconnection could enable advanced forms of power sharing and provide much-enhanced grid resilience.”

A future grid that features such converters would have the capability to control the flow of power between sections of the grid, shunting excess load or DER-based generation to feeder sections or adjacent circuits as needed, adding new versatility to power distribution. Networked microgrids could protect against the propagation of faults from one microgrid to the next while still allowing controlled power dispatch between the two systems and the macrogrid as well.

During outage recovery, microgrids could be formed that then stabilize neighboring microgrid systems, as envisioned in NREL’s autonomous energy systems research. In general, the two sides of the converter do not need to be synchronized in frequency or even exact voltage level at all — a major shift from the modern power system. But prior to proving any of these applications, NREL and others will first need to build the necessary controls.

“We are developing very novel controls for upcoming grid architectures,” Singh said. “We have local controls on inverters, and we have hierarchical controls that coordinate between grid partitions. With regard to grid support, these controls can do it all: dynamic stability, frequency support, black start, fault ride-through and protection.”

Unlike anything currently available, the NREL testbed provides an environment to validate medium-voltage grid solutions with real power hardware-in-the-loop and real-time grid simulation. For this project, NREL and partners are interested in the full range of use cases for back-to-back SiC converters and have teamed with utility Southern California Edison to inform on utility applications, as well as industry partners General Atomics and Eaton to seek out a commercial path for the technology.

The SiC converter is being built in two halves by project partners Ohio State University and Florida State University. The three-phase converter prototype will be rated for 330 kW and will implement a full thermal and electrical design appropriate for utility use. Traditionally, the same AC-to-AC conversion process requires stepping-down the voltage to low-voltage levels where conventional power electronics can be used, which results in heavy and expensive transformer equipment. The MV SiC option takes advantage of the superior voltage ratings of devices to minimize weight, cost, and size, which makes the technology far more practical and economical for system-wide deployment.

Still, the converter technology is only one aspect of fulfilling flexible interconnections. This framework currently lacks the standardization that exists for so many other recent grid innovations. At NREL, the project team hopes to collect baseline operational data to jumpstart the conversation around how to integrate MV converters in future grids.

“This is a new application that doesn’t exist anywhere yet. We need standards that apply to how the converters can integrate with regular system operation, like starting up, syncing to the grid, etc.,” Singh said. “We are using IEEE Standards 1547 and 2030.8 as a base, interpreting their rules to implement new controls on MV systems. We are trying to merge the two to understand what will apply to this new approach.”

An entirely new grid architecture and operational flexibility could seem far-out for now, but NREL and partners are showing that these options are viable in the near-term and that NREL has the capability to prepare these solutions for real systems. Learn more about how NREL can validate advanced energy systems at scale.

BYD takes the spotlight in the heart of Europe after sales surge by +750% in April

China’s EV leader is quickly making a name for itself in Europe. In April, BYD outsold Tesla in Germany and the UK as sales surged in the region. With new models on the way, this looks to be just the start of BYD’s global sales run.

BYD sales outpace Tesla in Germany and the UK in April

BYD is like a freight train right now. There’s no slowing its roll. The company sold over 380,000 new energy vehicles (NEVs) last month, up 21% from April 2024.

Like most Chinese automakers, BYD reports NEV sales, or electric (EV) and plug-in hybrid (PHEV) vehicles. Since it stopped making gas-powered cars in 2022, BYD has focused entirely on EVs and PHEVs. So far, it has paid off.

For the first time in over a year, BYD’s electric vehicles outsold its plug-in models. Last month, the company sold over 195,000 electric cars (+45% YOY) and nearly 176,000 (+0%) PHEVs.

Although its EVs got most of the attention, BYD sold over 79,000 vehicles overseas last month, its fifth straight month of growth. Through April, the company has sold over 285,000 vehicles in overseas markets, more than doubling from last year.

According to the latest sales numbers released by the German federal road traffic agency, KBA, BYD even outsold Tesla in Germany, Europe’s largest auto market.

BYD sold 1,566 vehicles in Germany last month, an over eightfold (+756%) increase from April 2024. In comparison, Tesla’s sales fell 46% with just 855 cars sold in Germany last month.

Closing the gap in Europe

Through the first four months of 2025, BYD sold 2,791 vehicles (+385%) in Germany, while Tesla remains ahead at 5,820 (-60%).

And it’s not just in Germany. BYD outsold Tesla in the UK last month as well. Data from SMNT shows BYD sold 2,511 vehicles in April 2025. Tesla only sold 512 vehicles in the UK last month.

BYD is quickly closing in on Tesla in the UK. Through April, BYD sold 11,782 vehicles while Tesla’s sales reached 12,986 vehicles.

Will China’s EV leader overtake Tesla in Europe? With several new vehicles rolling out, BYD is poised to see even more demand later this year. After launching its luxury Denza brand last month, BYD’s cheapest EV, the Seagull, is set to arrive later this year.

BYD will launch the low-cost EV later this year in Europe under the name Dolphin Surf with prices starting under £20,000 ($26,000). In China, the Seagull starts at under $10,000 (69,800 yuan) and was BYD’s top seller last month with over 55,000 units sold.

According to forecasts from S&P Global Mobility, BYD’s sales are expected to double in Europe from 83,000 last year to 186,000 in 2025. By 2029, that number could reach upwards of 400,000.

As it looks to drive growth this year, BYD is aggressively expanding overseas. BYD’s fourth car transport ship, the “BYD Shenzhen,” officially set sail last week with enough room for 9,200 vehicles. It is now the world’s largest.

Game-changing Lectric XP4 next-gen electric bike launched, shocking industry once again

Game-changing Lectric XP4 next-gen electric bike launched, shocking industry once again

In true Lectric style, North America’s largest e-bike company just unveiled the latest generation of its best-selling electric bike in a high-energy, adrenaline-fueled product launch this morning. The Lectric XP4 is the newest generation of the ultra-popular e-bike line, and once again brings a shocking level of upgrades at price points never before seen in the industry.

To put it simply, Lectric has done it again; they’ve absolutely crushed it and set a new high watermark for value in the US folding e-bike market.

The XP line is the best-selling electric bike in the US, so this was bound to be a hotly-anticipated launch. With roughly 1 out of every 10 electric bikes sold in the US being a Lectric XP (out of many hundreds of models available in the market), any new launch in the product line was set to grab eyeballs. And despite the extremely high expectations, Lectric appears to have risen to not only meet them but likely exceed what most could have expected at this price point.

The launch of the new XP4 actually includes a pair of launches, with the base 500W model offering the same $999 price tag we’ve come to know ever since the XP 2.0 days. A new long-range XP4, which swaps the 10.4Ah battery for a massive 17.5Ah battery and upgrades the motor to 750W, bares only a slightly higher $1,299 price tag.

“Because this model is so important to us and our riding community, we were determined to hold the line on price,” said Lectric eBikes co-founder and CEO Levi Conlow. “While other e-bike companies continue to raise prices and launch new products at higher price points, we know riders are going to appreciate Lectric going against the grain and making huge improvements for the same entry price we set more than four years ago.”

Levi isn’t paying lip service there, either. Both models share a number of key upgrades covering everything from the hardware design to the included componentry, and even the riding feel.

Both models include a new in-house designed torque sensor, offering smoother and more responsive pedal assist across the full range of power levels. A new 56-tooth chainring is larger and provides a more comfortable pedal cadence at higher speeds, meaning those taking advantage of the Class 3-capable 28 mph (45 km/h) speed can do so without their feet needing to spin uncomfortably fast.

The handlebars now feature an upgraded TFT color display with a built in USB-C port for phone and device charging. Having personally tested the e-bike yesterday, I can attest to just how beautifully designed the TFT screen truly is, providing much more information to the rider yet in a neatly laid out way that keeps it clear and easy to read, even in bright sunlight.

My full first ride experience will be coming soon, but first let’s continue with what makes these models so new and innovative.

The frame has been redesigned with a novel rack setup, a larger main frame tube to accommodate the longer-range battery, and a new handlebar stem that provides a more comfortable reach in the cockpit. That rear rack adds to both the bike’s appearance and utility, providing a color and styling accent but also offering more compatibility for accessories mounted to its round tubes while still maintaining the boxier tubes consistent with the design legacy across the XP models’ successive frames.

New hydraulic disc brakes were developed specifically for Lectric and provide punchier stops than the previous version’s hydraulic disc brakes. The brakes’ model number of 602 even pays subtle homage to the area code in Phoenix, Lectric’s headquarters.

The transmission also received an upgrade, with the lower tier 7-speed Tourney derailleur getting replaced with a step up in Shimano’s hierarchy to an 8-speed Altus.

Other hardware improvements on the bike include the quick-release pedals, which have been redesigned, increasing the quality and making them easier to use. The new derailleur is matched with new trigger shifters on the right side of the handlebars paired with Lectric’s upgraded locking ergonomic bar ends. The new shifters and bar ends required a new throttle though, resulting in an updated left-side paddle-style thumb throttle.

The lighting on the XP4 has also been upgraded, now including rear turn signals.

The keyway for locking the battery has been relocated to the non-drive side of the main tube, making it easier to access, and is located next to a newly designed cover for the charging port and on/off button for the battery.

Like all of Lectric’s e-bikes, the XP4 is compliant with UL2849, and the two battery sizes are both compatible with a 5A fast charger that provides a full recharge in either 2 or 3.5 hours for the smaller or larger battery option.

New 20×3.0 tires include a mixed-terrain tread with a novel design that creates a smoother center patch for quieter riding on smooth surfaces like asphalt but retains enough knobbiness on the edges for better grip in off-road riding conditions. The tires’ quiet ride has been specifically designed to complement the ultra-quiet Stealth motor that Lectric has brought from its other models to the new XP4.

Unlike the XP 3.0 that had previously been available in just white or black, the new XP4 comes in multiple color options, a nod to customers who often asked the company for more variety in colorways. The XP4 now includes color options of Stratus White, Tempest Gray, Raindrop Blue, and Pine Green. The bike is also available in two frame styles of standard and step-over.

Pre-orders are now open for the XP4, priced at either $999 or $1,299 for the 500W and 750W versions, with shipping expected to begin next month.

Electrek’s Take

It’s hard to overstate how big of a deal the XP4’s launch is, especially considering that the starting price has remained the same affordable $999. At a time when tariffs are forcing other companies to increase prices, the XP4 stands head and shoulders above other folding e-bikes in the US market, not just on price but also on features.

If you take the $1,299 long-range version with the 750W motor and 840Wh battery, it’s easy to see how far ahead it is of the competition. If the only thing Lectric had done was put that big battery and torque sensor in it, the bike already would have surpassed any other leading brand’s folding e-bike on value. There just isn’t another torque sensor-based 840Wh folding e-bike out there at this price point. But then Lectric went so much further. All of the additions are like a mountain of cherries on top of an already alluring XP4 sundae. From the beautiful new TFT display to the super punchy new brakes, from the upgraded derailleur to the quieter tires and motor, from the easy-to-use quick-release pedals to the improved ergonomics of the handlebars – it’s just more heaped on top of more.

The one feature I wish they would have included would have been Apple FindMy integration to allow for easy tracking of a lost or stolen e-bike. Trust me, I tried to plant the bug in Lectric co-founder and Chief Innovation Officer Robby Deziel’s ear, but to no avail. Oh well, maybe but there’s still hope for including location tracking on the XP5.

There’s one thing for sure though: Everyone else is still competing for second place against Lectric. That’s nothing new, but now the gap between Lectric and others has continued to grow. There was already no better option when it comes to bang-for-your-buck in the folding e-bike space, and now Lectric has grown that value gap even further.
