On September 21st, NIO held an Innovation Tech Day. At the opening, Li Bin made an interesting remark: people always think NIO's strength is just service, which he takes issue with—NIO invests heavily in technology too. Throughout his presentation, Li Bin repeatedly used a phrase: systematic efficiency.

What Is Systematic Efficiency?

Literally, it's not the efficiency of a single product or team—it's the operational efficiency of the entire company system. What does this system include? R&D? Sales? Manufacturing? Financing? After-sales?

Today I'll look at NIO's 12 technology pillars to explain my understanding of NIO's systematic efficiency.

Smart Manufacturing

Li Bin has said on multiple occasions that partnering with JAC (Jianghuai Automobile) was a crucial innovation for NIO. Six years later, looking back, it clearly played a vital role.

First, it accelerated delivery of the first mass-produced vehicle, the ES8. NIO, XPeng, and Li Auto were all founded around the same time (within 7 months of each other in 2015). NIO ES8 deliveries began on May 31, 2018. Second, it dramatically reduced early factory construction investment, allowing NIO to spend more on other capital-intensive areas.

But contract manufacturing is a double-edged sword—it brought widespread skepticism about vehicle quality. However, once quality stabilized and external doubts faded, the advantage became clearer: when sales are slow, building your own factory means idle capacity risk falls entirely on you. With contract manufacturing, that risk transfers to JAC.

Where did the money NIO saved on factories go? One battery swap station costs ,000. At the time, NIO had over 1,600 swap stations, totaling about 9.3 billion yuan in investment—roughly equivalent to building its own factory. NIO took the money saved from not building a factory over 5 years and invested it in battery swapping. Everyone has factories, which gives no differentiation—but battery swapping could become NIO's trump card.

Battery Systems

When discussing battery systems, Li Bin repeatedly emphasized seven words: chargeable, swappable, upgradable. These seven words capture the essence of NIO's battery system systematic efficiency.

Chargeable is the baseline. Swappable is the differentiator—NIO took the capital savings from not building a factory and poured them into swap infrastructure. A key test of a business decision: are competitors copying it? By 2023, SAIC, BAIC, and other traditional OEMs were also investing in swap infrastructure—validating NIO's forward-looking strategy.

Upgradable is even more demanding, and a natural result of swappability. What does upgradeable mean? A 70kWh battery that's degraded after five years can be upgraded to a brand new 100kWh battery. Vehicles designed with swap-in-mind complete a battery upgrade in just 3 minutes. Without swap-in-mind design, that takes days.

Chargeable, swappable, upgradable also means batteries can be leased or sold separately. Thus the battery—the biggest EV cost component, 20-30% of total BOM—can be separated from the vehicle price.

Panoramic Connectivity

This brings us to the NIO Phone. NIO's infotainment system already includes many smartphone apps, but when engineers try to add more, some scenarios can't be satisfied by apps alone. Phone-car interaction is getting closer, becoming two daily consumer terminals. The scenarios for connecting them are rich.

NIO can't adapt to every smartphone. That's likely why NIO built its own phone. Rather than building a phone for users, NIO built a phone for itself—to make phone-to-car control and interaction smoother, richer, and more innovative.

Vehicle Engineering

Vehicle engineering sits at the center of the 12 technology pillars, with the other 11 serving it. NIO highlighted three keywords: software-defined vehicle, rapid iteration of smart EVs, and balance between personalization and platform efficiency.

Second point: rapid iteration. Software CI/CD is just the foundation. What drives rapid iteration is connecting the full flow: requirements intake, architecture design, development, hardware/software testing, and in-vehicle validation. Back in 2017, NIO summarized its iteration speed as: three months per major iteration, one month per minor iteration.

Third point: balancing personalization with platform efficiency. NIO positions itself as a user-centric company, taking far more personalization requests than traditional OEMs. NIO had eight models but only two mechanical platforms—NPC and NTB—both dual-motor. This shows the bigger differentiation should come from software. Personalization doesn't mean different software for every model—it means covering as many models as possible within as few versions as possible.

Global Digital Operations

Although most teams used the same project management tool, its requirements management model didn't fit the automotive industry, it lacked strong quality management support, and had almost no test management support—giving different teams huge freedom. Each team built different requirements management and test management tools based on their prior experience, creating different process quality architectures. This became a hidden risk for later global digital operations.

Li Bin took a very open attitude, which later influenced my own startup: when a company starts with nothing, don't worry about ideas being stolen. Design open, trusting organizational structures. But regardless, you need enough transparency to achieve true systematic efficiency.
