FYI: A Nio driver recently demonstrated the exceptional range of the startup’s 150-kilowatt-hour "semi-solid state" battery pack by traveling an impressive 554 miles on a single charge.
Nio’s Game-Changing Battery Technology
Nio, a Chinese electric vehicle startup, is making waves not only for its innovative vehicles but also for its cutting-edge battery technology. A recent test by a Nio owner has highlighted the incredible potential of the company’s new 150-kilowatt-hour "semi-solid state" battery pack, achieving a remarkable range of 554 miles before needing a recharge.
The Growing Popularity of Battery Swapping in China
China’s electric vehicle market is renowned for being advanced, with EVs that are affordable, sophisticated, and ever-evolving. One feature that deserves more attention is battery swapping. Nio has become a dominant player in this space, offering an efficient alternative to conventional charging. Nio owners can swap depleted batteries for fully charged ones at any of the company’s numerous "Power Swap" stations.
Testing the Limits: Ran’s Epic Road Trip
A YouTuber named Ran recently documented his experience using Nio’s 150-kWh battery pack. He replaced his Nio ET5 sedan’s standard 75-kWh battery with the larger pack at a nearby Power Swap station and set off on a cross-country journey. Starting with a 93% charge, Ran’s ET5 estimated a whopping 981 km (609 miles) in range. Over the course of his journey, Ran managed to travel 554 miles, showcasing the potential of this substantial battery upgrade.
What Makes the 150-kWh Battery Unique?
-
Size and Efficiency:
- In the U.S., large batteries typically power hefty electric SUVs and pickup trucks, which generally deliver around 300-400 miles of range. In contrast, placing such a battery in a sleek sedan like the Nio ET5 leads to vastly superior driving ranges.
- Semi-Solid State Technology:
- This battery utilizes a semi-solid-state design, which merges liquid and solid electrolytes to enhance energy density and potentially improve safety and charging speeds.
Performance and Real-World Implications
On his first day, Ran covered 398.4 miles, maintaining a 21% charge when he arrived at his destination. After an overnight recharge to 99%, he embarked on a more deliberate range test, ultimately driving 554 miles before the battery depleted.
While this result fell short of the 1,000-km range Nio advertises, it’s still an outstanding performance, especially considering the longest-range EV currently available in the U.S., the Lucid Air Grand Touring, is rated for 512 miles using a 118-kWh pack.
The Bigger Picture
-
Cost-Effectiveness:
- Ran paid approximately $42 for a two-day upgrade to the 150-kWh battery pack, illustrating how flexible upgrades can make long-distance EV travel more feasible and appealing.
- Practicality:
- Many EV users are concerned about range and charging times. However, the ability to swap batteries quickly and affordably can transform the EV driving experience, making it more convenient for lengthy journeys.
Conclusion
Nio’s battery-swapping technology and the introduction of the semi-solid-state 150-kWh battery pack offer a glimpse into the future of electric vehicle travel. With continued advancements, this approach could alleviate range anxiety and charging concerns, making EVs an even more attractive option for consumers worldwide.
