Nio’s Latest Electric Vehicle Achieves Remarkable 650-Mile Range with 150kWh Battery


Nio’s Electric Milestone: Achieving a 650-Mile Range

Chinese automaker Nio is set to revolutionize the electric vehicle (EV) landscape with its latest innovation—a cutting-edge “semi-solid state” 150kWh battery, the largest in any passenger car. Nio CEO William Li recently conducted an extraordinary endurance test, covering an impressive 1,044 kilometers (650 miles) in just 14 hours using the prototype version of the ET7.

The Technological Marvel Behind the Mileage

The groundbreaking feat was accomplished with a battery boasting a single-cell energy density of 360 Wh/kg, far surpassing Tesla’s latest cells. This semi-solid state battery, manufactured by WeLion New Energy Technology, employs gel, clay, or resin electrolytes, offering superior energy density and fire resistance compared to conventional batteries.

Flexibility through Battery Swap System

CEO Li emphasized the adaptability of Nio’s models, stating that all existing models can be seamlessly upgraded to the 150kWh ultra-long endurance battery pack through Nio’s battery swap system. However, the 150kWh battery will be available only as a separate lease, acknowledging its significant cost akin to an entire entry-level EV.

Implications for the U.S. Market

While this innovation propels Nio to the forefront of EV technology, the 150kWh battery may not make its way to the U.S. due to recent regulatory changes. The Biden administration’s rules impact electric cars, such as Tesla’s Model 3 Long Range, using specific Chinese battery components, affecting their eligibility for the full $7,500 tax credit.

Nio’s Distinct Battery-as-a-Service Model

Nio’s unique approach involves offering vehicles without a built-in battery, allowing consumers to subscribe to a battery-as-a-service (BAAS) monthly plan. This innovative service permits users to swap their batteries at any time, facilitating the adoption of larger and more advanced battery options.
