What type of battery does NIO use?
3 Answers
NIO vehicles are powered by lithium-ion battery packs supplied by CATL (Contemporary Amperex Technology Co. Limited). Here are key specifications about the NIO ES8 model: Battery Capacity: The NIO ES8 is equipped with a 70kWh battery pack, delivering a range of 355km under comprehensive driving conditions. Why doesn't NIO further increase the ES8's range? The primary reason lies in the vehicle's extensive configurations and powerful powertrain system, which result in significant curb weight and higher energy consumption. Achieving a range increase from 300km to 400km would require substantial trade-offs. Powertrain Performance: Taking the NIO ES8 as an example, it features dual motors with a power density of 2.89kW/kg. Each motor delivers a maximum power output of 240kW, with the combined system generating 653 horsepower (maximum power) and 840N•m of torque (maximum torque), enabling a 0-100km/h acceleration time of 4.4 seconds.
NIO primarily uses ternary lithium batteries, specifically high-energy-density products like nickel-cobalt-manganese lithium-ion batteries. I've personally followed their battery technology—models such as the ES6 and ET7 are equipped with these batteries, enabling a range that easily exceeds 500 kilometers, making them particularly suitable for long-distance travel. NIO also develops its own battery management systems and collaborates with suppliers like CATL to ensure high charging and discharging efficiency, with an 80% fast charge taking only about half an hour, saving time and hassle for daily commutes. Additionally, their Battery-as-a-Service (BaaS) offering is quite practical, allowing users to lease batteries and reduce upfront costs. I believe future upgrades to solid-state batteries will further enhance performance and safety, which is very appealing. Maintenance is straightforward—just avoid excessive discharge—and overall reliability is solid, providing peace of mind while driving.
Our family switched to the NIO ES8, and the battery performance has been impressive. It uses a lithium battery type, and the ternary system provides long-lasting range—just one charge per week is enough for commuting. The biggest surprise is the battery swap station, where you can get a fresh battery in just a few minutes, completely eliminating charging wait times, especially worry-free for long trips. Battery aging isn’t noticeable, and it remains stable even in winter. Plus, the app allows real-time monitoring, so you can use it with peace of mind. I’d recommend newcomers to look into their battery leasing option—it’s cost-effective and flexible, with low maintenance costs in the long run, which feels like a great deal. NIO’s service is quite attentive, responding quickly to minor issues and ensuring driving safety. Overall, from a practical driving perspective, this battery system is designed to be very user-friendly.
