EV Charger Connectors are what connect your electric vehicle to your charger or charging point and determine how fast you can charge. Understanding EV connectors and socket types is important for both EV drivers, charging station providers and installers as well as policymakers in order to achieve maximum efficiency from our EVs.
Most EV chargers use the Mennekes Type 2 plug, which is designed to be compatible with both AC and DC charging. This is the standard that is most popular for home charging, but public chargers can be equipped with CCS (Combo) or CHAdeMO connectors. Both of these are designed for DC fast charging, which can increase the speed at which you charge by up to 350 kW.
These fast charging connectors are built on top of the Mennekes Type 2 plug, and have two additional pins that are used for powering up your car during DC charging. During AC charging, these extra pins are closed off and the plug will look like a regular Mennekes Type 2.
For EV drivers in North America, there is also the Society of Automotive Engineers (SAE) J1772 connector, which is used by most major automakers to offer Level 1 and 2 charging for their EVs. Tesla cars, however, do not adhere to this standard and instead have a proprietary charging connector that is compatible with their own stations only.
Some EVs may have a third option, called the “granny cable,” which has a Type 2 connector on one end and a socket that fits into your car on the other. This is used for slow charging at home and at some public charge points, but it is not a great solution for on-the-go charging. EV Charger Connectors
