Price. Com-CHAdeMO disappeared in North America? What is more problematic than the charging specification is.

According to the environmental technology information website "CleanTechnica" in September, Electrify America (American charging service provider) announced that it will phase out CHAdeMO-compatible chargers from January 2022. This is no small news for EV owners and industry insiders at home and abroad.

At present, there are CHAdeMO, European CCS, North American CCS, GB/T (China) and Tesla's SC (SuperCharger) five fast charging methods (plug shape) in the world. The two CCS plugs have the same shape, but in Europe and North America, charge control methods are different and incompatible. GB/T is a Chinese specification. Tesla perfected the charging method of private specifications in his own company from the very beginning, believing that chargers are more important than sales stores in EV.

Among them, CHAdeMO is the world's leading standardized standard, and the corresponding chargers have been expanded in the European Union, North America and other countries. According to the view, this is the common specification of the world. Because the Nissan "Ye" of domestic EV adopts CHAdeMO, it has global development a long time ago.

Of course, other countries also have plans to use their own specifications as the world standard. There is also a view in the publication of EA that "North America has finally become a strategy focused on CCS." In fact, in North America, there are people who welcome a variety of standards (plug shape) to be reduced. Although each charging standard is not compatible, the conversion adapter completely exists. Car owners can reduce the number of prepared adapters and charging cards. Suppliers and vehicle manufacturers can also reduce product costs.

However, CleanTechnica also reported. "even if you now have EV that supports leaves and CHAdeMO (EV that supports CHAdeMO in North America is not just leaves), existing corresponding chargers still exist. In addition, Blink, EVGo and ChargePoint believe that CHAdeMO support will continue.

It is not clear whether other companies will follow EA's movement in the future, but unlike countries and manufacturers, it is difficult to unify charging standards. Even if the background of EV is global decarbonization and carbon neutrality, because regulation and national roadmaps are not monolithic. Because carbon neutrality is deeply dependent on the energy resources and infrastructure of various countries and regions, compared with looking for the ideal of the European Union, the situation of Japan, and the compromise plan of China, we have to follow the specifications and strategies of each region.

Even before EV, regional models existed due to subtle differences in emission controls and laws. If there are adapters with charging specifications that also change the shape of the plug and the charging control signal, it won't actually be a big problem. Perhaps, China, North America, the European Union and Japan will become the current mainstream, vehicles will be prepared to meet the export area of the charging port (and the corresponding firmware). The same is true for chargers. Originally, where the voltage, power contract and safety standards of AC power supply in each region and country are different, chargers should be designed for different countries.

In a nutshell, it can be considered the same as the charging plug of a smartphone. USB varies in size from type A to C, An and B in mini and micro sizes. And Apple's Lightning and other chaotic state, so far can not be unified. When it comes to whether this brings fatal inconvenience to users, there are plenty of conversion cables and adapters, including third parties. With the improvement of function and battery capacity, the update of connector specifications is inevitable. The EU wants iPhone plugs to be the standard, but it is also a competitive area for private companies, so it cannot simply be called integration.

In the same situation as smartphones, you have to get up in the EV charging specification. At the beginning, the reduction of EA's CHAdeMO is also one of them, but in the automobile industry, with the high performance of EV, the improvement of charger output capacity has become a topic. Especially in high-end cars and future popular small trucks and other commercial vehicles, the capacity of batteries has a tendency to increase. Tesla, Audi, Mercedes and other places 60-90kWh is a standard. In China, EV above 100kWh is also broadcast.

When this level is reached, if it is not a charger with an output of more than 50kW, the charge per unit time will be reduced and the efficiency of external charging will become worse. Tesla was originally a separate specification, equipped with 70~120kW SC from the very beginning. The adapter can be charged with either CCS or CHAdeMO, but it is more efficient to charge with a dedicated SC. Although we have developed our own charging network, according to the data collected from driving vehicles, SC can grow to the best point. Therefore, Tesla's charger grid (the destination charger for SC and AC200V general charging) also contributes to the satisfaction of car owners.

Porsche is also used in EV's commodity power strategy, including the charging environment. Porsche announced plans to install 90-150kW chargers for Taikang and future high-power EV. CHAdeMO specifications for Japan, but take the high-power chargers of Porsche dealers as a differentiation factor. In addition, Porsche's charging voltage is also 800V (the other is 400mm 500V), corresponding to the high voltage, while improving the charging efficiency, promoting the thermal countermeasures and operational advantages of cables and connectors.

At present, the charging standard is turning to the question of how to compare the higher output of uniform (plug shape). The EV up to section C does not require output, but considering the expansion of the charging infrastructure, the multi-port operation of the large output charger is inevitable. Instead of setting up multiple 50kW chargers, it is better to adjust the charging equipment of 100kW and 150kW and set the ports to 2 or 3. In the case of congestion, the maximum output is used separately according to the number of connected units, but if it is empty, you can charge 100kW and 150kW.
