An EV from Chinese language producer Nio will quickly go on sale with a "semi-solid state" 150kWh battery (140kWh usable) that's the biggest in any passenger automotive, Car News China reported. To indicate 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 autos.
The take a look at 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 typical 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 post (Google translation). "Extra importantly, all fashions on sale might be flexibly upgraded to 150kWh batteries by means of the Nio battery swap system."
Actually, the ET7's 150kWh battery will solely be out there on a lease separate from the automotive, a lot as we've seen with some automobiles offered in Europe. Beforehand, the corporate mentioned that the battery alone would price as a lot as a complete automotive (the corporate's entry-level ET5 EV), or round $42,000.
Manufactured by WeLion New Vitality Expertise, the battery has a single-cell power density of 360 Wh/kg or 260 Wh/kg for the complete pack (Tesla's newest cells are beneath 300 Wh/kg). Semi-solid state batteries use gel, clay or resin electrolytes, providing higher power density and fire-resistance than present batteries. Nevertheless, they're nonetheless removed from the promised land of full solid-state batteries, which may feasibly double power density.
We possible received't see the 150kWh battery pack stateside, although. With the Biden administration's newest guidelines, some US automobiles like Tesla's Model 3 Long Range that use particular Chinese language battery parts will now not obtain the complete $7,500 tax credit score.
