The charging speed is decided by three factors---the charging station(the source of power), the charging cable and the on-board charger. As a professional connectors & cable manufacturer, we will give you a brief introduction to an important part of every charging cable - its connector.

AC connectors

The first electric vehicles used inductive connection to charge, and the current was transmitted through electromagnetic induction. However, this charging method did not prevail because it was not efficient. Low efficiency leads to the requirements for conductive connection. One of the requirements of the connector is to establish a connection with the deck and the infotainment system.

A square plug named J1772 was designed in 2001, but it only had a power of 6.6 kw. In 2008, a new plug with a power of 19.2 kw was designed, and since 2010 it has become the standard for all American vehicles. This design is the new J1772, which is often called J-plug or Type 1.

Previously, electric cars in Europe also had this type of connector, so some older or hybrid cars are still equipped with Type 1. Now Type 1 is mainly used in America and Asia. There is a main disadvantage of this plug that it allows the use of only one phase and it doesn't support built-in automatic locking system.
