The charging interface used for electric vehicles (EVs) at charging piles, also known as charging stations, depends on the type of charging standard supported by the station and the EV. There are several charging standards in use around the world. I'll provide an overview of the most common ones:
Type 1 (SAE J1772): This standard is primarily used in North America and Japan. It features a rectangular-shaped connector with five or seven pins, depending on whether it supports AC or DC charging. Type 1 connectors are used for slower charging, typically up to 7.4 kW.
Type 2 (IEC 62196 or Mennekes): Type 2 is widely used in Europe and has gained popularity in other regions as well. It features a circular connector with either seven or nine pins. Type 2 connectors support both AC and DC charging and can handle higher power levels, ranging from 3.6 kW to 22 kW or more.
CHAdeMO: This fast-charging standard was initially developed in Japan but is now used globally. It uses a unique connector with multiple pins arranged in a T-shape. CHAdeMO supports high-power DC charging, with some stations capable of delivering up to 150 kW.
CCS (Combined Charging System): CCS is an international standard developed by a consortium of automakers. It combines the Type 2 connector for AC charging with additional pins for high-power DC charging. CCS supports charging power levels similar to CHAdeMO and is becoming increasingly common, especially in Europe and North America.
Tesla Supercharger: Tesla has its proprietary charging system, primarily used for their vehicles. Tesla Superchargers use a unique connector designed specifically for Tesla vehicles. They support high-power DC charging and are exclusive to Tesla vehicles.
It's important to note that the availability of different charging interfaces may vary based on the location and the specific charging station. Many charging stations offer multiple connector types to accommodate different EV models and standards.
