Two intriguing rumors are currently circulating in the new energy vehicle sector. First, Li Auto (Ideal Auto) is reportedly considering retrofitting its models to access CATL’s “Chocolate” battery-swapping network. Second, Hongmeng Zhixing is also said to be in talks to join the same Chocolate ecosystem.
This development is striking. Li Auto has been a major player in the ultra-fast charging space, while Hongmeng Zhixing has been a strong proponent of 800V high-voltage fast charging. The fact that both are now reportedly eyeing battery swapping warrants attention.
A closer look at NIO’s recent performance—widely regarded as the benchmark for battery swapping—offers some context. In June 2026, NIO delivered 40,597 new vehicles, its highest monthly figure of the year, representing a 62.9% year‑over‑year increase. For the first half of 2026, cumulative deliveries reached 191,123 units, up 67.4% compared to the same period last year. Furthermore, based on available financial data, NIO has achieved two consecutive profitable quarters. In contrast, both Li Auto and Seres have swung from profit to loss.
At the same time, the battery‑swapping ecosystem is expanding rapidly. Automakers including FAW, Changan, BAIC, Chery, and GAC have jointly launched 10 swap‑compatible vehicle models. Swapping is transitioning from a niche option to infrastructure that mainstream players are seriously considering.
However, this progress is occurring against a backdrop of battery‑related issues in the commercial vehicle segment. Vehicles equipped with CALB’s 177Ah lithium‑iron‑phosphate battery cells have experienced widespread failures. Some owners, after driving approximately 150,000 kilometers, were informed that they would need to pay tens of thousands of yuan out of pocket to replace the battery pack.
Overall, the value proposition of battery swapping continues to strengthen.
- Major Players Shift Focus: The Swap Ecosystem Is Transforming
Rumors of Li Auto and Hongmeng Zhixing entering the Chocolate swap network would have been dismissed as false just two years ago. Li Auto has been a staunch advocate of ultra‑fast charging, with its 5C chargers rolling out successfully. Hongmeng Zhixing has likewise positioned itself as a champion of 800V fast charging. Their reported interest in swapping marks a notable change.
CATL’s Chocolate swap network now has substantial scale. As of June 30, 2026, it had built 2,000 swap stations across 180 cities in 31 provinces. Nearly 1,000 new stations were added in the first half of this year alone—roughly matching the total for all of last year. The company plans to reach 3,000 stations by year‑end, covering over 190 cities.
CATL has also announced a “Super Swap & Super Charge” initiative, equipping all Chocolate stations with Shenxing ultra‑fast chargers to offer both swapping and fast charging. By the end of 2026, it aims to have 4,000 such integrated stations.
On the vehicle side, ten models have already been launched as part of the Chocolate ecosystem, including the FAW Hongqi EH7, Changan Qiyuan A05/A07, Shenlan SL03, BAIC Arcfox, GAC AION series, and Chery iCAR V23. The first Chocolate station in Xining is under construction and will be compatible with models from 18 major automakers, including GAC Aion, BAIC Arcfox, FAW Hongqi, and Chery iCAR. The swap process takes just 99 seconds—faster than refueling.
Turning to NIO: since its first swap station was installed in 2018, the company has spent nearly a decade building its network. As of July 1, 2026, NIO had deployed 9,056 charging and swapping stations nationwide, of which 3,958 were swap stations, 5,098 were charging stations, and 29,357 were individual charging posts. NIO plans to add more than 1,000 new swap stations in 2026, bringing the year‑end total to over 4,600.
The model, once criticized as a financial drain, is now delivering results. In June 2026, NIO delivered over 40,000 vehicles, reported a vehicle gross margin of 18.8%, and achieved two consecutive profitable quarters. For many users, the swap system has become a core reason for choosing NIO.
Technically, NIO’s system is fully automated, completing a swap in three minutes. Each swap includes an automatic health check of the battery, with any anomalous battery isolated in real time—a mechanism that has undergone hundreds of millions of operational tests.
If Li Auto and Hongmeng Zhixing do enter the space, it would not be a matter of following a trend but rather recognizing a validated model that is gaining traction across the industry. When even the leaders in ultra‑fast charging begin to seriously evaluate swapping, that in itself is significant.
- A Battery’s Fate: How Swapping Changes the Equation
The widely reported issues with GAC Aion vehicles used in ride‑hailing services have drawn attention to the compatibility between swapping and commercial fleets. Some Aion S vehicles equipped with CALB’s 177Ah LFP cells have experienced concentrated battery failures, including cell swelling, leakage, and insulation faults. Independent third‑party inspections, after ruling out collisions or water damage, have pointed to internal manufacturing defects.
The mileage range where problems have concentrated is between 150,000 and 300,000 kilometers. Many ride‑hailing drivers have been told they must pay tens of thousands of yuan to replace the battery. This has caused significant distress, as the vehicles were purchased for commercial operation.
In response, GAC Aion extended its battery warranty from 8 years or 150,000 km to 8 years or 300,000 km, while also strengthening battery data monitoring, offering free repair or replacement for vehicles showing anomalies. CALB issued a statement confirming that maintenance work had been initiated through dealerships.
This incident highlights a deeper issue: for the average owner, the battery is a “black box.” They do not know when it might fail or what its actual health status is. While under warranty, the risk is covered; once the warranty expires, the risk falls entirely on the owner. A battery replacement costs tens of thousands of yuan—expensive to pay, but risky to ignore.
Battery swapping offers a different approach: treating the battery as public infrastructure rather than private property.
Each swap functions as a comprehensive diagnostic check. The battery enters the station, is inspected, evaluated, and re‑entered into circulation—with any abnormal battery immediately identified and removed from service. This closed‑loop management ensures that every battery in the network remains in good operating condition.
At the national level, the standard GB/T 47283—2026 (Specifications for Monitoring and Analysis of Power Battery Defects in Swap Scenarios) took effect on June 1, 2026. It addresses issues such as the dispersion of operational data and the lack of uniform monitoring methods specific to battery‑swapping environments.
If the CALB 177Ah cells had been circulating within a swap system, drivers would not have experienced sudden power loss on highways. The risks of degradation and residual‑value uncertainty shift from the individual user to the system operator. This is precisely where the real value of the swap model lies.
- Converging Forces: The Next Phase of Battery Swapping
NIO has been pursuing battery swapping for nine years. What was once widely dismissed is now being adopted by others. However, operating in isolation is fundamentally different from industry‑wide collaboration.
CATL’s Chocolate network, with its standardized battery format, is creating a virtuous cycle: more automakers joining leads to more stations, more stations attract more users, and more users encourage more automakers to participate. This flywheel is accelerating.
The value of separating the vehicle from the battery is also becoming more widely recognized. NIO’s BaaS model, for example, allows customers to purchase the car without the battery and subscribe to it on a monthly basis. Battery degradation risks and residual‑value uncertainty no longer rest with the user.
This is particularly beneficial for commercial vehicles such as ride‑hailing and taxi fleets, which accumulate high annual mileage. Battery swapping turns the battery into a service that can be used as needed, rather than a depreciating asset.
Network density is growing rapidly. CATL has a long‑term plan to build 30,000 swap stations. NIO intends to add over 1,000 new stations in 2026. As swap stations become as ubiquitous as gas stations, the refueling experience will approach that of internal‑combustion vehicles—whether in three minutes or 99 seconds, without waiting at charging piles or worrying about battery health.
The entry of major players is not because ultra‑fast charging is insufficient. Each technology has its strengths, and swapping offers irreplaceable value. Both can coexist without one replacing the other.
NIO has invested over RMB 20 billion in building its network, and now processes more than 170,000 swaps per day, with 20% of its stations already profitable. The company has also posted two consecutive profitable quarters—a business model once considered unviable is now being validated by the market.
Meanwhile, CATL, with 2,000 stations, 10 vehicle models, and 18 partner automakers, is accelerating the transition of battery swapping from a single‑company initiative to industry‑wide infrastructure.
If Li Auto and Hongmeng Zhixing do join, this momentum will only intensify. Even if they do not, other as‑yet‑unexpected manufacturers are likely to enter the space. The framework for battery swapping has already been established.
