FAQs
Can I install an EV charger at my home?

HDB residents generally use public EV charging stations, although some HDB car parks are equipped with chargers.
Which EV charger should I choose?
The best EV charger depends on your vehicle model, driving habits, available electrical capacity, installation location, and future charging needs.

We will assess your requirements, and recommend the most suitable charger for your applications — ensuring the best balance for performance, reliability, features, and value.

How long does an EV charger installation take?
Most residential EV charger installations can be completed within one day, provided all approvals and site preparations are in place. The actual installation time depends on the site conditions, cable routing, electrical work required, and the scale of the installation. For commercial projects involving multiple chargers or additional electrical infrastructure, the installation timeline will vary based on the project's size and complexity.
Do EV chargers need approval before installation in Singapore?

EV chargers can only be installed in designated parking spaces, such as private home garages, landed property car porches or private car parks, designated parking lots in conodominiums and other residential developments. The installation must also comply with the property's requirements and Singapore's relevant safety regulations.

Installing an EV charger in a condominium typically requires the following: Approval from the Management Corporation Strata Title (MCST), appointment or approval of a Charge Point Operator (CPO) when applicable, and compliance with Singapore's electrical and safety regulations. Some government support schemes may also be available to help offset the cost of installing shared EV chargers in condominiums.

Our team will advise you on the next steps during our site assessment and consultation.
Will the EV charger you install be compatible with my electric vehicle?
Yes. Most EVs in Singapore use the Type 2 (AC) and CCS2 (DC) charging standards. This makes them compatible with the majority of EV chargers installed locally. We will recommend a charger that is fully compatible with your vehicle and your charging requirements. If you have any enquiries, or are not sure whether your EV is suitable with the chargers we provide, get in touch with us directly — and we will advise further.

This is one of the most common questions we usually get from homeowners. Before recommending an EV charger to you, our team will assess your electrical distribution board (DB), and available electrical capacity to determine the most suitable charging solutions. If required, we can also carry out load testing to verify your property's available capacity, and recommend solutions such as dynamic load management, or an electrical supply upgrade if necessary.
Is EV charging dangerous?
Not at all. By pairing your vehicle with the right certified chargers, this ensures both your property and your safety when using the product. Certified chargers usually include multiple safety features such as overcurrent protection, earth leakage protection, overvoltage protection, and temperature monitoring. Our team will go through with you the safety features of the products during installation so you need not worry about potential hazards.
Will charging my EV at home increase my electricity bill?
