Differences between single-phase and three-phase chargers for electric vehicles

At V2C, as leaders in the design and manufacturing of electric vehicle chargers, we know that one of the biggest concerns for those looking to buy an electric car is optimising charging time.

As experts, we always recommend installing a charging point at home or in your shared residential garage. In this guide, we explain the differences between three-phase and single-phase chargers, their benefits, and when to choose one or the other depending on your needs.

What is a three-phase charger and how does it work?

A three-phase electric car charger is a charging system that uses three phases of alternating current, allowing more energy to be transferred to the vehicle in less time. This technology is particularly suited to those who want to optimise charging times and make the most of the available electrical infrastructure.

• Provides much faster charging than single-phase systems.
• Ideal for homes with three-phase supply, businesses, and public charging stations.
• Ensures efficiency and balance across the grid, avoiding unnecessary consumption peaks.

At V2C, we develop three-phase chargers that adapt to any type of installation. Our best-selling models, such as Trydan and Trydan Pro, are available in three-phase versions. These chargers are perfect for homes or residential communities.

Can an electric vehicle be charged with three-phase supply?

Yes, as long as the vehicle is compatible and the electrical installation allows it. A three-phase supply multiplies the available power, significantly reducing charging times and enabling more efficient energy management.

• The car must support three-phase charging.
• The installation must comply with current regulations and be certified.

Why choose a three-phase electric car charger such as Trydan?

Choosing the Trydan three-phase charger means choosing smart, efficient charging that meets the new demands of modern electric mobility. This charger combines power, connectivity, and sustainability in a single device.

• Dynamic power control that optimises consumption in real time, automatically adjusting charging according to demand while keeping the installation stable.
• Innovative photovoltaic integration, unique in its class, even prepared for off-grid self-consumption systems, enabling maximum use of available solar energy.
• Seamless wireless connectivity with most inverters on the market, eliminating complex configurations and ensuring easy use from day one.
• Automatic reset system that ensures continuous operation of the charger, even after supply interruptions or variations.
• Advanced technology, designed to deliver superior energy performance and flexible installation, suitable for both residential and professional environments.

Manufactured in Spain, Trydan is the ultimate solution for those seeking maximum efficiency, solar compatibility, and safe charging backed by first-class engineering.

What is a single-phase electric car charger?

A single-phase electric car charger is a charging solution that uses one phase of alternating current, the same as is typically present in most households in the UK. This type of charger is perfectly suited to residential infrastructures, providing efficient charging for the majority of compact and urban electric vehicles.

At V2C, we design single-phase chargers that guarantee easy installation, safety, and compatibility with household energy needs.

• Suitable for standard domestic installations, without major electrical modifications.
• Ideal for electric vehicles with small to medium batteries.
• Efficient consumption and simple integration with the existing grid.
• Lower installation costs, making it perfect for residential users.

As experts in electric mobility, at V2C we recommend the single-phase charger for households seeking safe, simple, and convenient charging that fits seamlessly into daily routines.

Which is better: a single-phase or a three-phase charger?

The choice depends on charging needs and the characteristics of the electrical installation. A three-phase charger offers more power and faster charging, while a single-phase charger is sufficient for home charging and smaller urban vehicles.

Feature	Single-phase	Three-phase
Maximum power	3.7 – 7.4 kW	11 – 22 kW or more
Charging time	Longer	Much shorter
Installation	Common in households	Requires three-phase supply
Recommended use	Domestic, small cars	Businesses, fleets, larger cars

The three-phase charger is the recommended option for those seeking efficiency and speed. At V2C, we evaluate each case individually to offer the optimal solution.

Is three-phase supply better for charging a car?

Three-phase supply is preferable for vehicles with larger batteries or when the goal is to minimise charging times.

• Better management of contracted power.
• Reduced load on each phase, preventing overloads.
• Ideal for fleets, residential communities, and businesses.

Which cars support three-phase charging?

Most current mid- and high-end models, especially electric SUVs and long-range vehicles, support three-phase charging. It is essential to check the manufacturer’s technical specifications to confirm compatibility.

How much power do I need at home to charge an electric car?

The recommended power depends on the type of charger and the intended use. For a three-phase charger, a contracted power of at least 11 kW is generally advisable, though in residential installations it can be adjusted according to demand and the existing infrastructure.

• Minimum recommended power: 7.4 kW (single-phase) or 11 kW (three-phase).
• Personalised analysis for each home or business.

Is it better to charge an electric car with a three-phase or single-phase charger?

For efficient electric vehicle charging, it makes no difference whether the charger is single-phase or three-phase: the key is to use certified, high-quality chargers installed by professional electric vehicle charger installers.

It is also important to know that the best way to charge your EV is when the battery is at 20%, and you should avoid charging beyond 80%. Take advantage of the option to schedule charging with our smart chargers such as Trydan, and activate EcoCharging, our system that charges your car during the cheapest hours.
