Charging infrastructure plays a crucial role in the widespread adoption of electric vehicles (EVs). Currently, the Combined Charging System 2 (CCS2) is the standard charging system in Australia, supporting a wide range of EV models. However, with the emergence of Tesla’s Next-Generation Charging Standard (NACS) and its adoption by leading automakers, the question arises: Should Australia transition from CCS2 to NACS? This article explores the advantages of CCS2 over NACS and discusses the potential cost implications of such a transition.
CCS2 has gained prominence as a widely adopted charging standard due to several key advantages it offers. These advantages include:
- Compatibility and Interoperability: CCS2 supports both alternating current (AC) and direct current (DC) charging, making it versatile and compatible with a broad range of EV models. It ensures interoperability between different charging stations and EVs, enabling seamless charging experiences for users. This compatibility encourages EV adoption by reducing concerns about charging infrastructure availability.
- Wide Industry Support: CCS2 has gained significant industry support globally, with various automakers embracing it as their standard charging system. This support ensures that a wide range of EV models can leverage the CCS2 infrastructure, promoting compatibility and ease of use for EV owners.
- High Charging Power: CCS2 allows for high-power charging, enabling faster charging times for EVs. It supports power levels up to 350 kilowatts (kW), allowing for rapid charging at compatible stations. This fast charging capability is vital for enhancing the convenience and practicality of EVs, reducing charging downtime for drivers.
Australia has been utilizing CCS2 as its standard charging system for several years now. The country has seen a significant expansion of charging infrastructure, with every charging station being set up for CCS2 or Type 2 chargers. This widespread adoption of CCS2 ensures compatibility across a wide range of EVs and provides convenience to EV owners. The charging network in Australia has been built around CCS2, allowing for seamless charging experiences and promoting EV adoption.
Transitioning from CCS2 to NACS: Cost Considerations
While Tesla’s NACS has gained adoption by leading automakers globally, the decision to transition from CCS2 to NACS in Australia would require careful consideration of the potential cost implications. The costs associated with such a transition can be substantial and can be attributed to several factors:
Charging Station Adaptation:
Transitioning to NACS would necessitate significant modifications to the existing charging infrastructure. Since every charging station in Australia is currently set up for CCS2 or Type 2 chargers, adapting to NACS would require replacing the existing CCS2 charging equipment with NACS-compatible charging units. This process involves removing the CCS2 hardware, rewiring the stations, and installing Tesla’s NACS infrastructure.
Software and Network Integration:
In addition to hardware changes, integrating NACS into the existing charging network would involve software updates and network integration. Charging infrastructure providers would need to develop compatible software systems to enable communication with NACS-equipped vehicles and ensure seamless connectivity between the charging stations and the NACS network.
Training and Education:
Transitioning to a new charging system would require training and education for charging station operators, maintenance personnel, and EV owners. These stakeholders would need to become familiar with the new technology, operational procedures, and safety protocols associated with NACS.
Considering the substantial number of charging stations in Australia, the cost of transitioning from CCS2 to NACS would likely be prohibitively expensive. The expenses would include the purchase and installation of new NACS-compatible charging equipment, software development and integration, infrastructure upgrades, and the necessary training and education programs.
Conclusion
While Tesla’s NACS has gained adoption by leading automakers in the USA, transitioning from CCS2 to NACS in Australia would involve careful considerations of cost, compatibility, infrastructure implications, and the overall benefit to the EV ecosystem. CCS2 offers significant advantages in terms of compatibility, interoperability, and high charging power. However, the decision to transition would require a thorough evaluation of the potential costs involved and the benefits that NACS can bring to the Australian EV charging landscape.
This transition would also leave around 80,000 existing cars in Australia without a charging standard, as almost all EV’s (With the notable exceptions of some grey import Japanese Cars) would be left without a charging plug.

No three phase support is a deal breaker with our reliance on three phase power to businessess and also many homes. There are thousands of EVSEs out there set up on three phase power to deliver up to 22kw and many remote charging locations reply on mostly 32A amp 3 phase plugs to support up to the maximum charge rate for most EVs (11kw).
This one disadvantage completely outweighs the elegant and small size of the NACS plug.
I think the ultimate aim is to transition from 3 phase to 0 phase (also known as DC).
The situation at the moment is that each EV has some sort of charger, mounted in the vehicle, which is powered by AC line power – either single phase or 3 phase. However in future there will no compelling reason to carry around a charger in each car. Leave it on the garage wall.
