Svolt Energy, a battery supplier affiliated with Great Wall Motor, has unveiled its next-generation ion oscillation pulse charging technology. This innovation promises to reduce full charging times by 25% without increasing battery system costs, a key step toward making electric vehicles more convenient. The announcement came on January 13, 2026, during the company’s Battery Day event in China, with mass production scheduled for the third quarter of the same year.
Evolution of Charging Technology
Svolt Energy emphasizes this isn’t a breakthrough in battery chemistry, but an improvement to the charging process itself. The company frames it as a natural progression from earlier methods: constant-current charging, step charging, and multi-factor integrated charging. This latest iteration refines current control and charge sequencing to optimize lithium-ion movement within the battery.
The technology works by intelligently adjusting the current flow and incorporating short periods of “relaxation.” This allows lithium ions to redistribute more evenly, ensuring better integration into the anode material during charging. The result? A faster, more efficient charge.
Testing and Implementation
Svolt Energy reports that the 3.5-generation system has already undergone over 20,000 hours of testing to ensure stability and consistency. While exact vehicle-level charging power figures remain undisclosed, the company confirms the tech will be integrated into new-vehicle platforms from unnamed automakers starting in Q3 2026.
Beyond Faster Charging: Semi-Solid State Batteries and Stacked Designs
The charging breakthrough is just one piece of Svolt Energy’s broader roadmap. The company is also gearing up for volume production of its first-generation semi-solid-state batteries in 2026. These batteries, blending liquid and solid electrolyte components, achieve an energy density of approximately 270 Wh/kg and have already seen limited use in European passenger vehicles.
Furthermore, Svolt Energy is developing a medium-nickel semi-solid-state battery with a globally unique solid-electrolyte transfer technology. This design aims to reduce the risk of thermal runaway by 25% while maintaining an energy density of 245 Wh/kg for mid-to-high end EVs. A second-generation high-nickel semi-solid-state battery for eVTOL aircraft is also in development, boasting an impressive 342 Wh/kg energy density.
Finally, Svolt Energy is introducing Stacked 4.0 battery technology, which doubles the sheet count from its previous version to 16, improving efficiency by 100% and reducing per-Wh costs by 34%.
Svolt Energy’s aggressive development timeline, spanning from charging improvements to advanced battery designs, underscores the rapid pace of innovation in the EV sector. The company’s spin-off from Great Wall Motor in 2018 has clearly positioned it as a key player in the next wave of battery technology.
The rollout of these technologies in late 2026 suggests that Svolt Energy is prepared for seamless integration into production lines following extensive validation. These developments mean faster charging, safer batteries, and higher energy densities are on the horizon for the EV market.
