Here are the main advantages of the CCS charging standard over Chademo 2.0:
• Widespread adoption and compatibility. CCS is the dominant fast charging standard, supported by most automakers and charging companies. It is compatible with existing CHAdeMO fast chargers, allowing CCS EVs to charge at lower power. Chademo 2.0 is not backwards compatible and requires building all new chargers.
• Lower costs. CCS uses a similar plug design to CHAdeMO, so CCS vehicles and chargers tend to cost less to manufacture and deploy. Chademo 2.0 requires a new proprietary plug which can add to costs.
• Easier integration. It is simpler and less expensive for automakers to integrate CCS charging into their EVs since the technology is more mature and standardized. Supporting Chademo 2.0 may require more engineering work.
• Larger charging network. There are far more public CCS chargers available than Chademo 2.0 chargers. This provides more charging locations and coverage for CCS vehicle owners.
• Faster real-world charging. While Chademo 2.0 supports slightly higher peak power (400 kW vs 350 kW), real-world fast charging speeds may be similar for both standards due to limitations in charging technology, grid connectivity, and battery capabilities. CCS 350 kW is sufficient for most fast charging needs.
• Transition benefits. There are economies of scale benefits to converging on a single dominant standard like CCS. It avoids the inefficiencies of having to develop, build and maintain multiple standards. This will also make future improvements to fast charging technology easier to deploy across all chargers and vehicles.
• Policy and incentive support. Governments and utilities typically designate CCS as the standard for public and workplace charging incentives, rebates and infrastructure buildouts due to its higher adoption and lower costs. Chademo 2.0 may receive less policy and financial support.
In summary, CCS offers a compelling combination of benefits over Chademo 2.0 including lower costs, easier adoption, larger networks, faster real-world charging, transition efficiencies and more policy support. While Chademo 2.0 has theoretical faster peak power benefits, CCS is positioned to remain the leading fast charging technology for the coming decade.
Does this help summarize the key advantages of CCS over the Chademo 2.0 fast charging standard? Let me know if you have any other questions.
