Changan’s new solid-state battery delivers up to 1,500 km per charge, 70% safer and AI‑enabled diagnostics. Discover how this could reshape EVs today!
Introducing the “Golden Bell” Solid‑State Battery
The automotive world has long whispered that solid‑state batteries are the next big thing for electric vehicles. Chinese automaker Changan is turning that whisper into a roar.
Mass‑Production Timeline
Starting in Q3 2024, Changan will install the new solid‑state packs in prototype robots and test‑bed electric cars. Full‑scale production is slated for 2027 under the brand name Jingzhongzhao.
Unmatched Energy Density and Range
Changan claims the “Golden Bell” cells hit an energy density of 400 Wh/kg. In real‑world testing, vehicles equipped with these packs can travel over 1,500 km (about 930 miles) on a single charge. While the figure sounds ambitious, it would give future models the freedom to tackle long‑distance routes in remote regions where charging stations are sparse.
Safety Gets a 70% Boost – Thanks to AI
Beyond range, the new cells are designed to be 70 % safer than conventional lithium‑ion batteries. An integrated artificial‑intelligence system continuously monitors cell health, predicts potential faults and enables remote diagnostics, helping owners and service teams address issues before they become critical.
Strategic Production Mix
Changan will focus on fully solid‑state units while still maintaining parallel lines for liquid‑electrolyte and semi‑solid batteries. This diversified approach ensures a smoother transition for the market and safeguards supply‑chain stability.
The Wider Industry Race
Changan is not alone. Earlier this year, Dongfeng Motor began cold‑weather trials of its own solid‑state battery, boasting a 350 Wh/kg density and a claimed 1,000 km range, with commercial rollout targeted for September.
Domestic powerhouses such as BYD, Chery, SAIC, GAC and battery specialist CATL are all accelerating their solid‑state programs. Even global OEMs—Mercedes‑Benz, Volkswagen, BMW, Toyota, Nissan, Hyundai and Honda—have poured resources into this segment.
From Lab to Road
After years of headline‑making and laboratory milestones, solid‑state technology is edging toward practical, everyday use. If the performance metrics meet even a fraction of the hype, internal‑combustion engines could face a serious challenge in the years ahead.
Stay tuned as Changan and its rivals drive the next evolution of electric mobility.
