BYD, the world’s largest new energy vehicle (NEV) manufacturer by sales volume, today unveiled two game-changing innovations at its “Global Tech Summit 2025”: a next-generation solid-state battery with industry-leading energy density and a “SkyRail” intelligent urban mobility ecosystem integrating autonomous electric shuttles and renewable energy-powered rail transit. The announcements solidify BYD’s position as a technology pioneer in the global transition to sustainable transportation.
Next-Gen Solid-State Battery: 600 Wh/kg Energy Density, 10-Minute Fast Charging
BYD’s “Genesis” solid-state battery, developed through a decade of R&D, achieves an energy density of 600 Wh/kg—50% higher than current lithium-ion batteries—while enabling 10-minute fast charging to 80% capacity. The battery uses a sulfide-based solid electrolyte and a 3D lithium metal anode, eliminating liquid electrolytes and significantly reducing fire risks. Mass production is scheduled for 2026, with initial deployment in BYD’s premium sedan models, offering a 1,500 km range and a 20-year lifespan. Analysts predict the technology will reduce global battery costs by 30% by 2030.
SkyRail Ecosystem: Autonomous Shuttles + Renewable Energy Rail
BYD’s “SkyRail” integrates autonomous electric shuttles (capable of L4-level urban driving) with overhead monorail systems powered by solar and hydrogen energy. The first pilot project, launched in Shenzhen, connects 15 key districts via a 50 km SkyRail network and 200 autonomous shuttles. Passengers can seamlessly transfer between rail and shuttles using BYD’s “OneID” digital platform, which optimizes routes in real-time based on traffic and energy data. The system reduces urban carbon emissions by 45% compared to traditional transit and cuts commuting times by 30%.
Global Expansion: 1 Million NEVs Exported in 2025, Hungary Factory Ramped Up
BYD announced it had exported 1 million NEVs in the first seven months of 2025, a 92% year-over-year increase, capturing 38% of the European EV market. Its Hungary factory, now operating at full capacity, produces 200,000 units annually for the EU, ASEAN, and Middle East markets. The plant sources 75% of its components locally and uses 100% renewable energy, becoming a model for sustainable manufacturing.
Strategic Partnerships: Huawei for Autonomous Driving, Shell for Charging Networks
BYD signed agreements with Huawei to integrate its MDC 810 autonomous driving computing platform into BYD’s commercial vehicle fleet, targeting robotaxis and logistics trucks by 2026. It also partnered with Shell to deploy 5,000 ultra-fast charging stations across Europe by 2027, combining Shell’s energy expertise with BYD’s battery technology.
