Single-phase and three-phase systems are two different ways of transporting electricity. Single-phase and three-phase power supply in electric vehicles refers to the type of electrical system used to charge them.
In a single-phase power supply system, energy is delivered via a single phase and neutral. This is the most common type of power supply in homes. In electric vehicles, single-phase power is usually used with a household-type socket and can provide relatively lower charging power than three-phase power.
In a three-phase power supply system, power is delivered through three separate phases. This type of power supply is in industrial and commercial applications, where more electrical power is required. In recent years, the availability of public charging infrastructures for electric vehicles has seen the introduction of three-phase power supply for vehicle charging as well. The three-phase power supply provides higher charging power than single-phase power, reducing the overall charging time of electric vehicles.
