Singapore Introduces SS 722 Standard to Strengthen Electric Vehicle Charging Infrastructure

Singapore will elevate its national technical reference for electric vehicle (EV) charging systems to a full Singapore Standard from 1 April 2026, as part of efforts to support the rapid expansion of the country’s charging network. The move updates existing technical requirements and introduces clearer guidance for the design, installation, maintenance and operation of EV charging systems. According to the official media release, the change aims to improve safety, reliability and consistency across charging infrastructure nationwide.

The updated framework converts Technical Reference 25 (TR25:2022) into Singapore Standard SS 722. By formalising the standard, authorities intend to establish a common set of technical practices that can support both current charging technologies and emerging innovations in the EV ecosystem.

Strengthening Technical Standards for EV Charging

The new SS 722 standard expands on the previous guidance by incorporating updated specifications covering the full lifecycle of EV charging systems. This includes requirements for system design, installation procedures, operational management and ongoing maintenance.

Establishing clearer and more comprehensive technical standards is intended to ensure that EV charging stations across Singapore operate safely and consistently. Standardised practices also help infrastructure providers and operators maintain quality as the charging network grows across residential, commercial and public spaces.

Supporting the Expansion of Singapore’s Charging Network

Singapore has been steadily expanding its EV charging infrastructure as part of broader efforts to support cleaner transport and urban sustainability. The elevation of TR25 to SS 722 is designed to ensure that technical frameworks keep pace with this expansion while accommodating newer charging technologies entering the market.

Robust technical standards are also increasingly important as infrastructure becomes more digitally connected. Ensuring resilience and operational continuity across national systems aligns with wider initiatives to strengthen essential networks, such as the approaches discussed in Singapore’s efforts to improve critical network resilience.

Ensuring Safety and Reliability in Connected Infrastructure

As EV charging systems increasingly rely on connected technologies, safety and reliability standards are becoming more complex. Clear regulatory frameworks help ensure that equipment manufacturers, installers and operators follow consistent requirements across the sector.

This approach reflects Singapore’s broader emphasis on strengthening standards and governance for critical infrastructure, including initiatives aimed at raising cybersecurity standards for critical infrastructure. Establishing robust frameworks for new technologies helps maintain public confidence while enabling infrastructure development at scale.

With SS 722 taking effect on 1 April 2026, Singapore’s EV charging ecosystem will operate under a more comprehensive national standard, providing clearer guidance for industry stakeholders while supporting the continued rollout of charging infrastructure across the country.
