The quest for faster charging electric vehicles has taken a significant leap forward, with Finnish battery technology company Donut Lab demonstrating impressive results in real-world testing. In collaboration with Verge Motorcycles, Donut Lab’s solid-state battery technology has achieved charging times that could redefine the electric motorcycle experience, potentially paving the way for broader adoption of electric mobility. The tests, focused on a fully integrated battery pack within a production motorcycle, mark a crucial step beyond previous cell-level demonstrations and address skepticism surrounding the viability of solid-state battery technology.
For months, Donut Lab has been engaged in a public demonstration campaign, dubbed ‘I Donut Believe,’ aimed at proving the functionality and performance of its innovative solid-state battery. The latest results, released this month, showcase a battery pack charging from 10% to 80% capacity in just 12 minutes – a rate significantly faster than conventional lithium-ion batteries. This breakthrough isn’t just about speed; it’s about addressing a key barrier to electric vehicle adoption: range anxiety and the inconvenience of lengthy charging stops. The implications extend beyond motorcycles, potentially influencing the future of electric cars, buses, and other forms of transportation.
The testing centered around the Verge TS Pro electric motorcycle, utilizing an 18 kilowatt-hour (kWh) battery pack designed and built by Verge Motorcycles. Unlike many current electric vehicle battery systems that rely on complex liquid cooling, the Donut Lab-powered pack employs a simpler air-cooled design. This simplification is particularly relevant for motorcycles, where space and weight are at a premium. According to Ville Piippo, CTO at Donut Lab, the air-cooled system maintained a peak charging rate exceeding 100 kilowatts (kW) for five consecutive minutes, equivalent to a 5C charge rate, while charging from 10% to 50%. Electrek reports that this sustained power output is notable for an air-cooled motorcycle battery pack.
Solid-State Technology: A Potential Game Changer
Solid-state batteries represent a significant departure from traditional lithium-ion technology. Instead of a liquid electrolyte, which can be flammable and prone to degradation, solid-state batteries utilize a solid electrolyte. This offers several potential advantages, including increased energy density, improved safety, and faster charging times. Though, scaling up production of solid-state batteries has proven challenging, with issues related to manufacturing costs and maintaining consistent performance across multiple cells. Donut Lab’s recent tests aim to demonstrate that these challenges are being overcome.
The high energy density of Donut Lab’s technology allows for flexible battery pack designs, enabling manufacturers to offer different energy capacities within the same physical pack size. This adaptability is a key selling point, as it allows for customization to meet specific vehicle requirements without compromising space or weight. Piippo emphasized that even smaller battery packs utilizing their technology can deliver substantial energy capacity, offering manufacturers greater design freedom. This flexibility could be particularly valuable in the motorcycle market, where riders often prioritize agility and lightweight construction.
Real-World Performance Metrics
The recent tests yielded compelling charging time results. The battery pack reached 70% charge in just over nine minutes, and a full charge to 80% was achieved in approximately 12 minutes. These figures represent a threefold improvement over the charging speed of Verge Motorcycles’ previous generation lithium-ion battery packs. Interesting Engineering highlights that the battery maintained the 100kW peak charging rate for a sustained period, demonstrating the stability of the technology under real-world conditions.
Tuomo Lehtimäki, CEO of Verge Motorcycles, stated that the technology aligns perfectly with their goal of providing an optimal user experience. He envisions the Verge TS Pro becoming “the world’s fastest-charging motorcycle,” leveraging the benefits of Donut Lab’s solid-state battery technology. Verge Motorcycles currently offers the battery pack used in the test as a standard option, with a larger capacity version available that provides approximately two-thirds more energy capacity.
Addressing Skepticism and Looking Ahead
Donut Lab’s emergence has been met with considerable scrutiny, particularly given the ambitious claims surrounding its solid-state battery technology. The company’s debut at CES 2026 sparked debate within the industry, with some experts questioning the feasibility of achieving the promised performance levels. These recent pack-level tests represent a direct response to that skepticism, providing tangible evidence of the technology’s capabilities in a real-world application. The shift from testing individual cells to a complete battery pack is a critical step in validating the technology’s scalability and reliability.
The simplicity of the thermal management system – relying solely on air cooling – is another noteworthy aspect of the design. This eliminates the complexity and weight associated with liquid cooling systems, making it particularly well-suited for motorcycles. The air-cooled design also contributes to the overall cost-effectiveness of the battery pack, potentially making solid-state technology more accessible to a wider range of manufacturers and consumers.
The Future of Electric Motorcycle Charging
The successful demonstration of Donut Lab’s solid-state battery technology in the Verge TS Pro has significant implications for the future of electric motorcycle charging. Faster charging times can alleviate range anxiety, making electric motorcycles a more practical option for a wider range of riders. The simplified thermal management system and flexible pack design further enhance the appeal of the technology, offering manufacturers greater design freedom and cost savings. The company’s ongoing research and development efforts are focused on further optimizing the battery’s performance and reducing manufacturing costs.
While the initial tests are promising, further validation and long-term durability testing are crucial. The performance of solid-state batteries over extended periods and under various operating conditions needs to be thoroughly evaluated to ensure their reliability and longevity. However, the recent results represent a major milestone in the development of solid-state battery technology and offer a glimpse into a future where electric vehicles can be charged as quickly as their gasoline-powered counterparts.
Donut Lab and Verge Motorcycles are continuing to collaborate on further testing and refinement of the battery technology. The companies plan to release additional data and insights as they become available, providing greater transparency into the performance and capabilities of the solid-state battery pack. The next phase of testing will likely focus on evaluating the battery’s performance in different climates and under more demanding riding conditions.
