The CHAdeMO charging standard has played a significant role in the development of electric vehicle (EV) infrastructure. Originating in Japan, this fast-charging system has evolved over the years, adapting to the changing needs of the EV market. This article explores the historical development of CHAdeMO, from its inception to its current status in the global EV landscape.
The Birth of CHAdeMO
CHAdeMO was developed in 2010 by the CHAdeMO Association, which was formed by the Tokyo
Electric Power Company and five major Japanese automakers. The name "CHAdeMO" is an abbreviation of "CHArge de MOve," which translates to "charge for moving." This name is derived from a Japanese phrase that suggests the time it takes to charge a car is akin to enjoying a cup of tea. The association aimed to create a standardized DC fast charge system that could be used across various EV brands and models.
The first commercial CHAdeMO charging infrastructure was commissioned in 2009, coinciding with the launch of the Mitsubishi i-MiEV. This marked the beginning of CHAdeMO's journey as a key player in the EV charging industry. By 2014, CHAdeMO had become a published international standard, recognized by the International Electrotechnical Commission (IEC) and the European Committee for Electrotechnical Standardization.
Expansion and Challenges
As CHAdeMO gained traction, it faced competition from other charging standards, such as the Combined Charging System (CCS) and Tesla's North American Charging System (NACS). In 2013, the European Commission designated CCS Combo 2 as the mandated plug for DC high-power charging infrastructure in Europe, posing a challenge to CHAdeMO's international adoption.
Despite these challenges, CHAdeMO continued to expand its reach. By 2023, there were 57,800 CHAdeMO chargers installed in 99 countries, with significant numbers in Japan, Europe, and North America. The CHAdeMO Association also worked on developing new standards, such as the ChaoJi connector, to enhance compatibility and charging capabilities.
The Future of CHAdeMO
The CHAdeMO standard has evolved significantly since its inception. The introduction of the ChaoJi connector, also known as CHAdeMO 3.0, represents a major advancement in charging technology. Released in 2020, ChaoJi supports charging at up to 900 kilowatts and is designed to be compatible with both CHAdeMO and the GB/T DC-charging standard used in China.
Looking ahead, CHAdeMO faces the challenge of maintaining its relevance in a rapidly changing EV market. As automakers and countries adopt different charging standards, CHAdeMO must continue to innovate and adapt. The development of Ultra-ChaoJi for megawatt charging is one such effort, aimed at supporting electrified heavy-duty vehicles, airplanes, and ships.
In conclusion, CHAdeMO's journey reflects the dynamic nature of the EV industry. From its origins in Japan to its global presence today, CHAdeMO has played a crucial role in shaping the future of electric vehicle charging.
