HPC: challenges and potential solutions
- New ChaoJi EVs will be able to charge with the existing CHAdeMO and GB/T chargers using an ‘inlet adapter’.- Existing CHAdeMO and GB/T EVs are not allowed to use any adapters, so they will need to use the dual
chargers during the transition period.- Backward compatibility with CCS is also technically possible, detailed specification is under consideration.

o Adaptability, Backward compatibility, Core values
(CAN / safety /interoperability, low impact to the grid)
o Prescribe the minimum
o Leave the rest to the market, especially communication
o Collaborate
