The dialogue platform “Elektromobilität im Dialog” and the industry information service electrive.net have initiated a debate. The question was as simple as difficult: Should Germany decide not to adept the CHAdeMO standard for its charging stations? CHAdeMO is the trademark for a brand overlapping electrical interface of a battery management system for electric cars, which was developed in Japan. Overall 1.239 opinions have been collected and analyzed. At the end there was a small advantage for the critics of CHdeMO which were more likely to explain the opinion with several arguments. However, the numbers of pro and against opinions have been equal.
The supporters of CHAdeMO are convinced that the exclusion of the standard would discourage potential new buyers of electric cars and would be a massive counterstrike against the pioneers of emobility. Many of the early adopters have bought cars with the CHAdeMO standard and would be punished for their courage. The supporters of the standard want to include these people and their cars. Also, the additional costs to integrate CHAdeMo with new charging stations would increase their costs by not more than five percent. The question they ask: Would anybody ever open a petrol station that only offers diesel but no benzine?
The opponents of CHAdeMO say that emobility is still at a very early stage which is an ideal opportunity to errect a homogeneous infrastructure which is free of any kind of fragmentation. An important decision at this stage will be the choice of one uniform fast charging standard. This is why the German car manufacturers and all big US-based car brands have agreed to use the CCS-technology (Combined Charging System). There are too many differences between CHAdeMO and the industry norms ISO 15118 and DIN 70121, which have been defined for Europe. CHAdeMO is also too expensive the design of the plug is not user-friendly.
Both groups have many good and much more arguments for and against the standard – it is now up to the consumers to decide.
