CCS2

What CCS2 is

CCS stands for Combined Charging System. The “2” refers to the Type 2 AC base - the round, 7-pin connector that handles AC charging. CCS2 adds two larger DC pins below that standard connector, creating a combined plug capable of both AC and DC charging through the same port.

In simple terms: your everyday home or destination charging uses the upper 7 pins (Type 2 AC). Fast chargers use the full 9-pin connector, with DC current flowing through the two larger lower pins.

Australia uses CCS2, not CCS1

There are two CCS standards. CCS1 pairs DC pins with a Type 1 (J1772) AC connector - that’s the North American standard. CCS2 pairs DC pins with a Type 2 (Mennekes) AC connector - used across Europe and Australia.

This distinction matters when looking at imports or when using charging adaptors. A vehicle built for the North American market with a CCS1 port will not physically accept a CCS2 cable without an adaptor.

The Tesla shift

Until mid-2023, Tesla sold vehicles in Australia with a proprietary CCS2-adjacent connector. The Tesla-to-CCS2 adaptor existed but was clunky. From the Model 3 Highland refresh onward, new Teslas sold in Australia ship with a standard CCS2 port - meaning they charge on any CCS2 public DC fast charger without an adaptor. The Supercharger network has also been opened to non-Tesla vehicles via CCS2 adaptors in most states.

Speed capabilities

The CCS2 standard supports up to 350 kW DC charging theoretically. In practice, most chargers installed in Australia operate at 50 kW, 75 kW, or 150 kW. Ultra-rapid 350 kW sites exist primarily in metro areas - Brisbane, Sydney, Melbourne, Adelaide, Perth - with coverage expanding along major highway corridors.

The connector itself isn’t the limiting factor in charge speed. The charger’s output rating and the vehicle’s peak DC acceptance rate are what determine how fast you actually charge.

Reliability in the field

CCS2 connectors have been the subject of some criticism around latch reliability - the mechanism that locks the connector into the car during charging. Most issues are with older or poorly-maintained charger units rather than the standard itself. If a connector doesn’t click in cleanly, it’s worth trying a different cable on the same unit, or a different charger entirely, rather than forcing it.
