Type 2 Connector

The Type 2 connector is the standard plug used for alternating-current charging of electric vehicles across Europe and much of the rest of the world. Developed by the German firm Mennekes and adopted as the European norm, it replaced an earlier patchwork of incompatible plugs and gave the continent a single, predictable AC charging interface. Both the socket on the car and the connector on home wallboxes and public AC points use the same seven-pin layout, so almost any European EV can charge at almost any AC charger with the appropriate cable.

The connector carries up to seven contacts arranged in a flattened circular face: a protective earth, two signalling pins, and up to three live phases with a neutral. That three-phase capability is the defining feature. Where a single-phase supply limits charging to around 7.4 kW, a three-phase Type 2 link can deliver 11 kW or 22 kW, and bespoke installations push higher still. The two smaller signal pins handle the control pilot and proximity functions defined by the IEC 61851 standard, allowing the car and charger to negotiate the available current and to confirm the cable is properly seated before any power flows.

For the driver this brings real benefits. A locking mechanism secures the connector during charging so it cannot be unplugged by a passer-by or vibrate loose. Because the standard is universal across the region, owners can carry a single Type 2-to-Type 2 cable and use the great majority of public AC chargers, many of which present only a socket and expect the driver to supply the lead. The actual charging speed at home is usually capped not by the connector but by the car's on-board charger, which converts the incoming AC into the DC the battery needs.

The connector is formally standardised as IEC 62196 Type 2, and its design has proved flexible enough to underpin Europe's rapid-charging infrastructure as well. The Combined Charging System version 2, or CCS2, simply adds two large DC pins beneath the familiar Type 2 face, so the upper half of a CCS2 inlet is geometrically a Type 2 socket. This means a single port on the car accepts both everyday AC charging and high-power DC fast charging, with the appropriate pins energised in each case.

A few practical points are worth noting. Type 2 is an AC-only connector in its standalone form; it cannot itself carry the high direct currents used at motorway rapid chargers, which is precisely why CCS2 exists. Many homes have only a single-phase supply, so the headline 22 kW figure is often unattainable domestically regardless of the cable. Tesla used Type 2 connectors on its European Superchargers for several years, an unusual case of an AC plug being repurposed for DC, before the network broadly moved to CCS2. Understanding the connector therefore means understanding its place within the wider family of AC charging, on-board chargers and the CCS standard it helps form.
