The Government of Singapore has upgraded its electric vehicle (EV) charging framework by elevating Technical Reference 25 to a full national standard.
The revised standard introduces tighter technical requirements to improve the safety, reliability and consistency of EV charging infrastructure across the country. It expands the regulatory scope to cover wireless power transfer, mobile charging systems and battery swapping for two-wheelers, four-wheelers and heavy goods vehicles. The framework also brings in stricter electrical safety norms, enhanced temperature controls, stronger cable integrity checks for direct current charging systems, cybersecurity provisions and guidelines for smart grid integration and smart charging. A transition period of two and a half years has been provided before compliance becomes mandatory for new chargers.
