In the market we can find different connectors for charging electric vehicles, depending on the manufacturer of the vehicle itself, the charging protocol used or the type of charger used, whether it is in alternating current (AC) or direct current (DC).

Connector Type 1

Charging in alternating current -AC- (Mode 3). Type 1 connectors are mainly used in the Asian and American market, although they can also be found in Europe and other countries. It is a single-phase only connector, designed to charge with a maximum current of 32 A (7.4 kW) in the European market. It has two main load poles (L1; N) plus one pole for protective earth. It also has two contacts for communication between the charger and the vehicle (PP; CP). It also has a locking device that prevents disconnection of the connector during recharging.

Connector Type 2

Charging in alternating current -AC- (Mode 3). Currently, this is the connector approved as the European standard for public AC charging. It is designed for recharging in single-phase or three-phase systems, depending on the vehicle’s needs and power availability. It allows single-phase loads from 16 A / 230 V to three-phase loads at 63 A / 400 V, which means that it is possible to recharge in alternating current from 3.7 kW to 44 kW.

It has four main load poles (L1; L2; L3; N) plus one pole for protective earth. In addition, it has two contacts for communication between the charger and the vehicle (PP; CP).

Connector Type CCS2

Direct current (DC) charging (Mode 4). It is a combined connector for DC fast charging and is currently the connector approved as the European standard for DC public charging. It allows direct current charging, which is the fastest type of recharging available. Allows loads up to 500 A / 1000 V (350 kW).

On the vehicle side, it allows charging the vehicle in AC Mode 3 and DC Mode 4 (not at the same time) through a single socket, which is the key to the success of this connector. It has two main poles for recharging (DC +; DC -) at the bottom and at the top it keeps the shape of the AC Type 2 connector to maintain communication (PP; CP; PE).

CHAdeMO connector

Direct current (DC) charging (Mode 4). This connector was developed by a partnership of Japanese companies as a connector for fast DC charging. It allows direct current charging, which is the fastest type of recharging available. It allows loads up to 200 A / 500 V (100 kW).

Most Japanese electric vehicles are equipped with this connector, as well as the Type 1 connector for slow alternating current recharging. It has two main poles for recharging (DC +; DC -), two contacts for communication between the charger and the vehicle (CAN communication) and five contacts for analog control.
