<\/p>\n it will be mandatory for Singapore-registered vehicles to be fitted with the OBU<\/p>\n
<\/a> as the country switches fully to the next-generation Electronic Road Pricing (ERP) system.<\/p>\n
Since Dec 2, 2024, Tesla cars delivered to customers with pre-fitted OBUs have been equipped with the iRoad Powerpack Pro 12, made by a South Korean company known for in-car cameras. <\/p>\n
From January 2026, older Teslas that need to retrofit OBUs after delivery will use a customised external battery device, which was developed by local engineering company Hope Technik. <\/p>\n
It uses lithium iron phosphate battery cells, similar to the iRoad model. LTA said that such batteries are also used by major electric vehicle manufacturers. <\/p>\n
The installation of the OBU and external battery system for Teslas has to be done by Indeco Engineers, and there is no charge if the installation is done within three months of the notification by text message and e-mail from LTA to do so.<\/p>\n
Like the OBU, the customised device is tested against the International Electrotechnical Commission\u2019s IEC-60068 and IEC-60529 standards \u2013 to withstand environmental conditions like temperature, humidity, vibration and shock, and for resistance to dust and water, respectively. <\/p>\n
LTA added that these standards are widely used to assess the operational reliability of electronic devices.<\/p>\n
So far, around 4,200 Tesla cars have been fitted with the iRoad model and 380 have the customised unit. As at the end of 2025, there are 8,635 Teslas in Singapore. In total, about 930,000 vehicles, or 93 per cent of the vehicle population, have been fitted with OBUs.<\/p>\n<\/div>\n
