BEIJING – April 24, 2026 – The 2026 Beijing International Automotive Exhibition officially opened its doors yesterday, and SVOLT Energy seized the spotlight with the global debut of its "Fortress Battery 2.0" — the highest-capacity plug-in hybrid (PHEV) battery ever put into mass production. The milestone cell made its first public appearance inside the all-new GWM WEY V9X, a large luxury six-seat flagship plug-in hybrid SUV developed on the premium "Guiyuan S Platform" and positioned as an "AI-powered luxury flagship."

Tailor-made for large and premium plug-in hybrid vehicles, the Fortress 2.0 delivers an industry-leading capacity of 80kWh (at 1/3C rate), making it the largest-capacity PHEV battery currently in global mass production. This energy density feat translates into an all-electric range of over 400 kilometers (248+ miles) on a single charge — eliminating range anxiety for daily commuting and long-haul hybrid driving. Beyond raw capacity, the pack boasts a torsional stiffness of 30,000 Nm/deg, a threefold improvement over standard industry benchmarks, and its underbody withstands impacts up to 1,000 joules without failure.

Charging performance is equally revolutionary: the Fortress 2.0 supports peak 6C fast charging, allowing the state of charge to leap from 10% to 80% in just 10 minutes. For the first time, SVOLT applies nano‑thermal ceramic insulation material, ensuring that the pack remains non‑flammable even at extreme temperatures exceeding 1,000°C. Cell side‑crush resistance surpasses China’s national standard by more than double, and the battery cells survive triaxial continuous extrusion without fire or explosion — a testament to robust structural, thermal, and electrical full‑link redundancy design.

Mid‑April saw the first mass‑production batch of Fortress 2.0 roll off the lines at SVOLT’s Changzhou plant. The "high‑capacity PHEV" segment is projected to be the fastest‑growing powertrain category between 2026 and 2028, and SVOLT has secured a clear first‑mover advantage in the premium hybrid space by being the first to deliver a production‑ready 80kWh PHEV battery.

SVOLT Energy continues to pursue a dual‑track technical roadmap, balancing nickel‑cobalt‑manganese (NCM) ternary and lithium‑iron‑phosphate (LFP) chemistries. On the LFP front, the company’s "Hexagon Short Blade" battery serves as the core driver for bringing ultra‑fast charging to the mass market. Short blade cells are already deployed globally with major OEMs including Stellantis, Hyundai Motor, VinFast, and GWM, demonstrating multi‑market scalability. On the ternary side, SVOLT leverages solid‑liquid hybrid electrolyte technology to substantially mitigate safety concerns, and has already achieved mass production of semi‑solid state batteries for diverse applications. With deep expertise and proven industrial scaling across both chemistries, SVOLT is poised to respond swiftly to differentiated needs for BEVs, EREVs, HEVs, and beyond, delivering safer, more efficient, and cost‑effective electrified mobility solutions for end users.

As Fortress 2.0 makes its public debut at the Beijing show and enters series application, drivers can finally bid farewell to the twin anxieties of safety and charging downtime. The era of high‑capacity, ultra‑fast plug‑in hybrid mobility — delivering uncompromised freedom — has officially arrived.
