Maintenance of the EV Charger:
(Generally applicable to MCSTs, once your electric car charging station has been installed) We may begin asset management, that includes billing reconciliation processes and the operation and management of your electric vehicle charging system’s software. Finally, a periodic inspection of your charger’s hardware will be carried out along with your respective licensed electrical worker (LEW) after your installation works have been completed. Current regulations recommend a quarterly inspection of your installation.
Cost of the EV Charger:
The cost of installing your own electric car charging station will vary depending on a couple factors:
- How much cable concealment works need to be laid out for your electric car charging station?
- Will the charging station be installed indoors or outdoors, how much trenching and cable bearing is required?
- What is the power availability on your switchboard?
- Are there specific modifications you may require?
- Choice of your electric car charger: DC chargers are faster therefore costs more than AC chargers that charge slower.
Typically in Singapore, the EVs onboard chargers accept around 7 to 11kW AC, with some of the higher tier models offering 22kW AC as an added option. What this means is that, if your EV's onboard charger supports only up to 11kW AC, you will not be able to optimise the full benefits of a 22kW AC wall charger. It is capped by the EV's specification, so make sure you check with your EV manufacturer.
Full Renewable Spectrum:
Is an option that anyone can have! You may choose to have your home and your electrical charging station complemented with solar energy. How this works is, with solar power generated from the panels on your roof, you will offset your daily electricity usage. At the same time, excess solar energy can automatically be stored into your battery energy storage system (BESS). This can be supplied to your electric car charger, to be used whenever your car is ready to be charged.
When it comes to installing an electrical car charging station in your home, it is best to work with industry professionals you trust to aid a smooth process without hassle.
