The emerging world of electric vehicles (EVs) continues to push boundaries and redefine the limits of automotive transport, with solid-state battery technology at its cutting-edge. Recently, a refreshed NIO ET7 equipped with an impressive 150 kWh battery pack, comprised of 95% solid-state electrolyte, has completed a noteworthy milestone in the EV landscape. This battery pack has shown its capability to drive an EV for more than 600 miles on a single charge in three unique test scenarios, marking a significant step forward in the quest for more extended-range electric vehicles.
With increasing focus pivoting towards semi-solid electrolyte technology, as opposed to fully solid-state batteries, the world’s EV industry is navigating through the hurdles of cost and resource availability. Despite challenges initially faced with its main battery supplier over the development of a 150 kWh pack with this technology, NIO pursued an alternative path. The partnership with startup WeLion led to the fruition of the new semi solid-state battery pack, though not without surpassing its initial deadlines and budget constraints.
Triumphantly, NIO has now embarked on producing its near-solid-state electrolyte battery in sufficient quantities to begin equipping its future vehicle models. The ET7, a premium sedan, will be one of the first vehicles to showcase this innovative battery when it receives its refresh announcement on April 25.
To commemorate the technological advancement, NIO conducted significant real-world range tests with the ET7 utilizing the solid-state battery. The new battery-powered sedan has undergone a series of tests in different driving conditions, impressively maintaining a distance of at least 650 miles on a single charge across all of them. Notably, the vehicle also reported an efficient energy consumption rate of 13.0 kWh/100 km, rivaling smaller and less powerful models on the market.
An exceptional aspect of these range tests was the consistency in average speed and performance even under varied driving conditions and geographical changes. These tests not only emphasize the extended range capabilities but also the reliability and adaptability of the new battery technology in real-world scenarios.
On the horizon, a critical factor remains — the cost of the ET7 model equipped with the innovative 150 kWh semi solid-state battery pack. Initial anticipation suggested the price might equate to that of the smaller ET5 sedan; however, with mass production underway, manufacturing costs could potentially see a reduction, making it more accessible to consumers.
As the automotive world turns its attention to the forthcoming debut of the 2024 NIO ET7 at the Beijing Auto Show, electric vehicle enthusiasts eagerly wait to learn more about the pricing and availability of this ground-breaking sedan on April 25th.
This pivotal event may set new precedence within the EV industry, as the 650-mile range test opens up possibilities for a future where electric driving is no longer limited by range anxiety but is propelled forward by the promise of long-duration travel on a single charge.
