CCS2, also called Combo 2, builds on the Type 2 connector by adding two high-current DC pins underneath. A single inlet on the car accepts either a Type 2 plug for AC charging or a CCS2 plug for DC fast charging.
CCS2 has become the de facto DC standard for electric cars in India and Europe. When choosing a public fast charger, filtering for CCS2 is usually the right choice for a modern electric car.
