Donut Lab has released results from a fast-charging test conducted with Verge Motorcycles, showcasing the performance of its Donut Battery technology at full battery-pack level rather than individual cell testing. The system is used in Verge’s TS Pro electric motorcycle.
The test forms part of ongoing research into how multiple battery cells operate together within a complete pack, with a focus on energy density, thermal behavior and fast-charging capability in real-world conditions.
According to Donut Lab, the Verge TS Pro equipped with its battery technology charged in less than 10 minutes, making it “the world’s fastest charging electric motorcycle”, the company said.
“This is the first test we have published to a wider audience that demonstrates the performance and behavior of multiple battery cells in a real vehicle environment,” said Ville Piippo, CTO at Donut Lab. “The high energy density of our battery technology enables flexible battery pack design and superior performance even in more challenging applications, such as motorcycles, where space is limited and system simplicity is key. We are able to offer vehicle manufacturers packs with different energy capacities in the same physical size, with even the smallest packs having very high capacities.”
In the test, an 18kWh battery pack was charged using a public fast charger starting at approximately 20°C. The system reached a peak charging power of over 100 kW (around a 5C rate) for five minutes, with state-of-charge increasing from 10% to 50% in about five minutes. Overall, the motorcycle achieved a 10–70% charge in just over nine minutes, and 10–80% in approximately 12 minutes.
The solid-state-related battery architecture enables flexible pack design, enabling different energy capacities to be packaged within the same physical footprint, which is particularly relevant for space-constrained applications such as motorcycles.
“Our goal is to provide Verge users with the best possible user experience,” said Tuomo Lehtimäki, CEO of Verge Motorcycles. “The advantages of Donut Lab’s battery technology, such as ultra-fast charging, complement our goal seamlessly. The world’s fastest charging electric motorcycle, the Verge TS Pro, is also air-cooled. The battery pack used in this test is our standard model, but an extended range version is also available, with approximately two-thirds more energy capacity.”
