- The pack’s cells support peak charging rates of up to 6C, enabling a 10%-80% charge in under 10 minutes.
- Svolt achieved its first quarterly profit in the fourth quarter 2025 and aims to realize full-year profitability in 2026.
Svolt Energy has unveiled an 80-kWh battery pack for plug-in hybrid electric vehicles (PHEVs), claiming it has the world’s largest capacity.
The Chinese battery manufacturer rolled out the Fortress 2.0 pack at its sixth Battery Day event in Changzhou, Jiangsu province on Tuesday, targeting family car segment.
The battery pack features highly integrated system design, achieving a 6% increase in volume utilization and system energy density, Svolt Energy said.
Its cells incorporate ultra-fast charging graphite technology, supporting peak charging rates of up to 6C, enabling a 10%-80% charge within 10 minutes.
Notably, Leapmotor (HKG: 9863) debuted its D19 SUV on October 16. The extended-range electric vehicle (EREV) variant features an 80.3-kWh battery pack delivering up to 500 kilometers of range.
Both EREVs and PHEVs are hybrid vehicles, differing in that the EREV’s engine does not contribute to propelling the vehicle.
At Tuesday’s event, Svolt disclosed progress in its semi-solid-state battery R&D, announcing that its first-generation high-nickel semi-solid-state battery has achieved small-scale production. With an energy density of 270 Wh/kg, it has been installed in a model from a European passenger vehicle brand.
The second-generation high-nickel semi-solid battery, primarily designed for low-altitude aircraft, has completed development. With an energy density of 342 Wh/kg, it has undergone installation and flight testing in an eVTOL (Electric Vertical Takeoff and Landing) aircraft.
The mid-nickel semi-solid battery, targeting broader markets, will enter mass production in October 2026. Featuring an energy density of 245 Wh/kg, it will be used in mid-to-high-end passenger vehicles, the company said.
At Tuesday’s event, Svolt also unveiled its so-called 3.5th-generation ion oscillation pulse charging technology, which reduces charging time by 25% compared to its second-generation technology without increasing costs.
This charging technology has undergone over 20,000 cumulative hours of testing and will be deployed across multiple models on a customer’s new platform in the third quarter of 2026, the company said.
Svolt achieved its first quarterly profit in the fourth quarter 2025 and aims to reach full-year profitability in 2026, said Yang Hongxin, chairman and CEO of the Chinese power battery manufacturer.
The company targets 61 GWh of battery shipments in 2026, representing a 50% increase from 2025, according to Yang.
Svolt originated as the battery division of GWM (HKG: 2333, SHA: 601633), commencing R&D on power batteries in 2012.
It spun off from GWM in February 2018 to focus on next-generation battery materials, cells, modules, packs, BMS, and energy storage technologies.
The company ranked eighth in China’s power battery installations in November with 2.45 GWh and a 2.62% market share, according to data from the China Automotive Battery Innovation Alliance (CABIA).
