When it comes to fast charging technologies for electric vehicles, Tesla comes to mind with the patented Supercharger V3 fast charging network: Today’s third generation technology provides maximum charging power of up to 250 kW. And while there is still a long way to go for a variety of technologies like in the smartphone market (and this is certainly a good one), there are open alternatives. One of them is the standard CHAdeMO fast charging protocol developed by the Japan Electric Vehicle Quick Chargers Association, which has been recently updated to version 3.0.
A new version of the standard was developed in conjunction with the China Electricity Council. As a result, CHAdeMO 3.0 is compliant with the Chinese national standard for charging GB / T electric vehicles, creating favorable conditions for wider use. Additionally, the organization noted that as a result, CHAdeMO 3.0 may be compatible with the Combined Loading Standard (CCS).
The most important innovation is the reduction of the charging speed time by increasing the power up to 500 kW (with a maximum current of 600 A). The ability to transfer such high-powered energy makes the process of charging an electric car on time equivalent to the procedure of refueling a car with ICE gasoline or diesel fuel. According to rough estimates, in just five minutes, at a charging station that meets the CHAdeMO 3.0 specification, it will be possible to charge the battery of an electric vehicle to overcome more than 200 km of track. At the same time, 10 minutes of connection to CHAdeMO 3.0 should provide a full charge of the average electric car.
Of course, CHAdeMO 3.0 also sets certain requirements for compatible charging stations. The new generation CHAdeMO stations will be distinguished by a new connector, a smaller diameter cable with liquid cooling and the absence of a locking mechanism.
Later this year, the CHAdeMO 3.0 certification program should be launched. The plan is to first test CHAdeMO 3.0 in commercial vehicles in early 2021, and then expand the application of the technology to automobiles.
