- Changan delivered the first 1,000 Oshan 520 sedans built on CATL's battery swap standard for use as cabs.
- This marks the scale adoption of CATL Choco-SEB's standardized battery swap models in the mobility market.
Changan Automobile has started its first major delivery of a model based on CATL's (SHE: 300750) battery swap technology, marking a milestone for the latter in the battery swap segment.
The first 1,000 Changan Oshan 520s, built on CATL's Choco-SEB (swapping electric block) battery swap solution, saw the first 1,000 vehicles delivered in Chongqing, southwestern China, CATL's battery swap business unit announced yesterday.
The vehicles will be used as cabs, and a delivery ceremony was held on May 23. The event also saw the signing of 15,000 units of the model, according to the announcement.
The event marked the scale of use of Choco-SEB's standardized battery swap models in the mobility market and is a recognition of Choco-SEB in the market, the announcement said.
CATL has already completed 34 Choco-SEB battery swap stations in Chongqing, and the number of stations in the city will top 50 by the end of this year, according to the company.
The battery giant is targeting a total of 1,000 battery swap stations in 31 cities by the end of 2025.
The Oshan 520 is an electric sedan from Changan that entered a regulatory filing catalog in October 2024 with China's Ministry of Industry and Information Technology.
At the time, the regulatory filing showed that it was a battery swap-enabled model, prompting much speculation about which company's technology it used.
The answer came in November 2024, when Changan and CATL held a signing ceremony in Chongqing for a battery swap cooperation program.
Changan showed off the battery swap-enabled Oshan 520 electric sedan from its sub-brand Oshan at the event in November, saying the model could get a fully charged battery pack with a range of 500 kilometers in less than two minutes, bringing a new experience to shared mobility operators.
The Oshan 520 is based on CATL's Choco-SEB battery swap solution, which saves owners more than two hours of charging time per day, Changan said at the time.
