Nio Supports Singapore EV Charging and Battery Swap Standard Development

Singapore has introduced an updated electric vehicle charging and battery swap standard, marking a significant step in the development of EV infrastructure. The newly released Singapore Standard SS 722 now incorporates technical requirements for battery swapping and mobile charging systems, areas that were not formally covered in previous versions. Nio played an important role in the development process, contributing its expertise and operational experience gained from years of deploying battery swap technology across multiple markets.

SS 722 Expands Scope to Battery Swapping and Mobile Charging

The latest version of SS 722 introduces a dedicated section titled Electric Vehicles Charging System – Part 4: Battery Swapping and Mobile Charging System. This addition establishes technical specifications covering both passenger vehicles and heavy-duty trucks. The inclusion of battery swap and mobile charging requirements reflects growing industry interest in diversified charging solutions and supports the broader adoption of electric mobility technologies within Singapore and beyond.

How Nio Contributed to the New Standard

According to the company, Nio participated extensively in the development of the revised framework and was among the leading contributors involved in shaping technical requirements. The company stated that the release of SS 722 represents another milestone in the international standardization of battery swapping technologies. It also highlights how experience accumulated by Chinese electric vehicle manufacturers can contribute to the formulation of global mobility standards.

Nio's Standardization and Battery Swap Ecosystem

Standardization has been a strategic focus for Nio since its establishment. The company says it has led or participated in the development and revision of more than 50 national, industry, and association standards. In addition, it has contributed to four International Electrotechnical Commission (IEC) standards, helping advance technical alignment across the battery swapping ecosystem and supporting wider industry adoption of the technology.

Key Battery Swap and Infrastructure Metrics

As of June 10, the company had filed more than 1,650 battery swap patents globally. Its infrastructure network in China includes 3,904 battery swap stations, 5,056 charging stations, and 29,089 chargers. Nio also reported cumulative battery swap transactions exceeding 110 million, demonstrating extensive customer usage and large-scale operational validation of the technology.

Singapore's Role in Nio's International Growth

Singapore remains an important market within Nio’s international expansion plans. In May 2022, the company became the first Chinese automaker to secure listings in three markets after joining the main board of the Singapore Exchange. The market has since served as a strategic platform for the company’s regional growth and technology showcase activities.

In May 2023, Lawrence Wong, who was serving as Singapore’s Deputy Prime Minister at the time, visited Nio and reviewed its battery technologies. Wong later became the country’s Prime Minister in 2024. Such engagements have reinforced the visibility of advanced EV technologies and battery innovation within Singapore’s mobility ecosystem.

Firefly Supports Overseas Expansion Strategy

Earlier this year, Nio introduced the right-hand-drive version of the Firefly EV at the Singapore Motorshow 2026, making Singapore the first market to receive the model in that configuration. Deliveries of the initial batch began on February 1, further strengthening the company’s presence in the region. Firefly is expected to play a central role in Nio’s international growth plans as it expands into additional overseas markets.

Looking ahead, the company intends to continue advancing technological innovation while promoting the standardization of emerging mobility technologies. Nio also plans to collaborate with industry stakeholders to support the development of global standards and expand its international footprint to 40 countries and regions by the end of the year, with Firefly serving as a key growth driver.
