There is a lot of confusion among people around different types of connectors, the diagram below should make understanding it easier. In essence, on the supply side:
- Domestic 3-pin plug is the slowest form of charging intended for emergency usage only.
- The Commando plug is a higher amperage version of the above type and can provide higher power charging over single and three phases AC but is now depracated.
- Type-2 is the most common connector type found on domestic and public charge points.
- Rapid DC charge points are always found with charging cable tethered to it.
On the vehicle side:
- Type-1 is the only slow-charging connector scoket on vehicle side. This is mostly found in conjuction with the CHAdeMO rapid connector socket in EVs with smaller batteries. Manufacturers are gradually moving away from Type-1 to Type-2.
- Type-2 is the most common type of connector socket available in European-make EVs because of its versatility.
- CHAdeMO connector design belongs to a Japanese-led consortium and hence is found in most Asian-make EVs as the socket for Rapid charging.
- CCS (Combined Charging System) was more recently developed to have a single multi-function socket for all types of charging. It encompasses a single port for Type-2 connector socket and DC terminals as well. It is the more favoured design and is found in most modern EVs.
