Single-phase electrical supply is common in most households, consisting of two cables, one phase, and one neutral. In contrast, three-phase supply comprises four cables, three phases, and one neutral.
Three-phase current can deliver higher power, up to 36 KVA, compared to the maximum 12 KVA for single-phase. It is often used in commercial or business premises due to this increased capacity.
The choice between single-phase and three-phase depends on the desired charging power and the type of electric vehicle or charger pile you are using.
Plug-in hybrid vehicles can efficiently charge on a single-phase supply if the meter is powerful enough (6 to 9 KW). However, electric models with high charging power may require a three-phase supply.
Single-phase supply allows for charging stations with a capacity of 3.7 KW to 7.4 KW, while three-phase supports EV charger of 11 KW and 22 KW .
Transitioning to three-phase is recommended if your vehicle requires faster charging, significantly reducing the charging time. For example, a 22 KW charging point provides approximately 120 km of range in an hour, compared to only 15 km for a 3.7 KW station.
If your electricity meter is located more than 100 meters from your residence, three-phase can help minimize voltage drops due to the distance.
Switching from single-phase to three-phase may require work depending on your existing electric vehicle charging. If you already have a three-phase supply, adjusting the power and tariff plan may suffice. However, if your entire system is single-phase, a more substantial renovation will be necessary, incurring additional costs.
It's important to note that increasing the power of your meter will lead to an increase in the subscription portion of your electricity bill, as well as the total bill amount.
Now iEVLEAD EV chargers range single- phase and three-phase, cover residential charger stations and commercial charger points.
