Electric Vehicle Charging Systems For Singapore
A nationwide electric vehicle (EV) charging standard Technical Reference for EV Charging Systems (TR25) was established for the EV Charging System in Singapore. The TR25 sets out the technical standards and safety precautions for the design, installation and operation of chargers. The latest version of the technical reference is TR25:2016.
​
To ensure proper installation of the EV chargers, you are required to engage a Licensed Electrical Worker (LEW) to install, test and certify the fitness of the installation.
​
Before the installation of EVSE, the LEW shall check that the EVSE is issued with a Letter of No Objection (LNO) from EMA-LTA Interim Joint Panel (IJP) to ensure that it complies with the technical requirement of TR25:2016 or the relevant International Electrotechnical Commission (IEC) standards (as well as the essential tests stated in the Technical Compliance Checklist.
​
Next, the LEW will be required to certify the fitness of the EV charging installation before handing over the installation back to you.
Requirement of Letter of No Objection (LNO)
Any manufacturer, distributor, or motor dealer who wishes to provide fixed EVSE to consumers, is required to submit an application for a Letter of No Objection (LNO).
The application shall state the brand, model and power rating of the EVSE, with the relevant test report(s) and Certificate of Conformity of the EVSE attached for the IJP’s verification.
