An EV from Chinese language producer Nio will quickly go on sale with a “semi-solid state” 150kWh battery (140kWh usable) that is the biggest in any passenger automobile, Automotive Information China reported. To point out a lot vary that may ship, Nio CEO William Li drove a prototype model of the ET7 1,044km (650 miles) in 14 hours, a distance surpassing many gas-powered automobiles.
The check was run in comparatively cool temperatures (between 28 – 54 F) and livestreamed. Driving was achieved primarily in semi-autonomous (or Navigate-on-Pilot+, as Nio calls it), and speed-limited to 90 km/h (56 MPH). The common velocity was 83.9 km/h (a decent 52.4 MPH), with a journey time of 12.4 hours excluding stops.
“The completion of this endurance problem proves the product energy of the 150kWh ultra-long endurance battery pack,” mentioned Li in a Weibo put up (Google translation). “Extra importantly, all fashions on sale might be flexibly upgraded to 150kWh batteries via the Nio battery swap system.”
Actually, the ET7’s 150kWh battery will solely be obtainable on a lease separate from the automobile, a lot as we have seen with some automobiles offered in Europe. Beforehand, the corporate mentioned that the battery alone would price as a lot as a complete automobile (the corporate’s entry-level ET5 EV), or round $42,000.
Manufactured by WeLion New Vitality Know-how, the battery has a single-cell vitality density of 360 Wh/kg or 260 Wh/kg for your complete pack (Tesla’s newest cells are beneath 300 Wh/kg). Semi-solid state batteries use gel, clay or resin electrolytes, providing larger vitality density and fire-resistance than present batteries. Nonetheless, they’re nonetheless removed from the promised land of full solid-state batteries, which may feasibly double vitality density.
We possible will not see the 150kWh battery pack stateside, although. With the Biden administration’s newest guidelines, some U.S. automobiles like Tesla’s Mannequin 3 Lengthy Vary that use particular Chinese language battery elements will now not obtain the complete $7,500 tax credit score.
