1-Phase vs 3-Phase EV Charging: Main Differences

15 Mar.,2024

 

Every electric vehicle has a predefined number of phases for charging, and so does every AC charging station. 

Examples of electric cars with a single-phase on-board charger: Opel Corsa-e in the basic configuration, Mazda MX-30

Examples of electric cars with a three-phase on-board charger: Audi e-tron, Renault Zoe, Tesla Model X, BMW i3. 

Ideally, you should use a charging station with the same number of phases as your vehicle has. But it’s not always the case. So what happens if you’ve got one of the following combinations? 

  • 1-phase charger - 3-phase electric car
  • 3-phase charger - 1-phase electric car 

Your car will charge with one phase in any of these cases. The weakest link of the charging chain defines the max speed.
