A safe and seamless user experience is key to the end user’s overall acceptance and satisfaction within the EV ecosystem. Only a safe, reliable and convenient EV charging infrastructure can achieve this.
TÜV SÜD provides EV charging infrastructure testing and certification solutions to help EV charging infrastructure suppliers and operators overcome industry challenges. Our contribution to this sustainability journey is that the products are safe, reliable, and compliant with regulatory standards.
EV charging infrastructure testing and certification in Singapore
TR25:2016 and TR25:2022 – the national electric vehicle (EV) charging standard guides the safety requirements of EV charging systems and infrastructure across Singapore.
The EV charging infrastructure in Singapore includes the Type 2 AC and Combo-2 DC charging systems under the National Public Charging Standards (NPCS).
CHAdeMO – a fast-charging method for EV batteries – has been introduced as Optional Public Charging Standards (OPCS). This inclusion enhances the development of electric vehicle charging stations, providing a broader spectrum of public EV charging options.
These standards (TR25:2016, TR25:2022, the NPCS, and the OPCS) are in place to promote EV adoption in Singapore and ensure the safety, reliability, and convenience of EV charging infrastructure in Singapore.
