EV chargers: inspections and certificates

Public EV chargers in Singapore must be inspected by an equipment specialist once every six months under the TR 25:2022 and SS 722 technical references, with a further annual check. Ask the owner or operator for the certificate of fitness and the maintenance schedule. Homeowners do not need a licence to operate a home charger. Operators of charging services need a licence under the Electric Vehicles Charging (Licensing) Regulations 2023. One online discussion puts the market rate for EV charger maintenance at around S$200–250.

High-voltage safety for electric vehicles

Before any repair near the battery pack, drive motor or inverter of an electric vehicle, a technician must safely switch off the high-voltage system. Ask whether the technician is trained for that work. For UPS and inverter batteries, ask for the voltage reading before and after the service, and state the Ah rating printed on the battery, because batteries are quoted by capacity in Ah.

Heat and humidity all year

Singapore has no winter or summer: it is hot all year, with a wet season and a dry season. Heat shortens battery life, so a UPS or inverter kept in a hot utility room is worth checking early. A power cut during a storm is a good reason to book a battery test before the rainy weeks, not after the unit fails.

What to put in your request

Give the device type, the make and model, and the fault in one sentence, such as "beeps on power cut" or "charges only partly". State the battery size in Ah, the power rating in VA or kW, and whether you need a home visit. Add your city (Singapore, Tampines, Jurong West, Woodlands or Ang Mo Kio), the deadline you need, and your budget. A budget helps sellers suggest the right repair.

BlaBlaPrice is free for buyers. You describe the unit and the fault in your own words in a chat, and you can add a photo. The assistant asks for missing details, looks through sellers' websites and price lists in Singapore, and shows the prices and businesses it finds. Registered sellers reply in the chat with their own offer, price and visit terms, and your contact details stay hidden until you choose to share them.
