The Government of Singapore has upgraded its national electric vehicle charging framework, elevating Technical Reference 25 (TR25:2022) to a full national standard (SS 722), effective April 1, 2026.
The updated standard, led by Enterprise Singapore and supported by the Land Transport Authority (LTA), introduces enhanced technical requirements to improve the safety, reliability, and consistency of EV charging infrastructure across the country.
SS 722 expands the scope of EV charging regulations to include emerging technologies such as wireless power transfer, mobile charging systems, and battery swapping solutions for both two-wheelers and four-wheeled vehicles, including heavy goods vehicles. The standard also introduces stricter electrical safety requirements, improved temperature controls, and enhanced cable integrity checks for direct current (DC) charging systems. In addition, new cybersecurity provisions have been incorporated to protect charging infrastructure and communications systems, alongside guidelines for smart grid integration and smart charging capabilities to improve energy efficiency.
The revised framework aims to support the continued expansion of Singapore’s EV charging network while ensuring uniform technical practices across all installations. A transition period of two and a half years has been provided before compliance with SS 722 becomes mandatory for new chargers.
