Wireless and mobile charging join new EV standard

The new standard also covers battery swapping for heavy vehicles.

Singapore has updated its national standard for electric vehicle (EV) charging systems, expanding its coverage to include the latest technology.

In a joint statement, the Land Transport Authority and Enterprise Singapore said the Technical Reference 25 will be elevated to a Singapore Standard SS 722 effective 1 April.

The latest standard will “be expanded to include updated specifications and guidelines for the design, installation, maintenance and operation of EV charging systems in Singapore to enhance their safety and reliability.”

Amongst the key changes in SS 722 is the Electrical Safety and General Requirements to cater for new types of EV charging systems such as wireless charging stations, mobile charging systems, and battery charge and swap stations for four-wheeled vehicles.

Chargers that have already been type-approved under the EV Charging Act based on the earlier TR 25 standards do not need to be re-certified to the new SS standard. There will be a transition period of two and a half years before compliance with SS 722 becomes mandatory for new chargers.

“This elevation also supports the continued expansion of Singapore's charging network through standardised technical practices that ensure consistent quality across charging stations island-wide,” authorities said.
