In a significant advancement for electric vehicle technology, EVgo has unveiled its forthcoming 750-kilowatt charging system, set to revolutionize charging speeds. Promising to recharge next-gen EVs in a mere 10 minutes, this system will nearly double the speed of the fastest public chargers currently available in the US and Europe, with a full reveal planned for 2027.
The race to enhance EV charging infrastructure is intensifying. Earlier this year, ChargePoint introduced its Express Solo DC fast-charging station, boasting a 600 kW power delivery. Meanwhile, automakers from China, such as BYD, along with European manufacturers and charging tech companies, are working on liquid-cooled Megawatt Piles capable of recharging compatible EVs in under five minutes. This rapid charging innovation is set to benefit not only everyday drivers but also full-electric heavy trucks and electric air mobility vehicles.
The 750 kW Charging System
EVgo’s 750 kW chargers will implement the North American Charging Standard (NACS), initially pioneered by Tesla, which most upcoming North American EVs will adopt. This strategic move aims to expand EVgo’s network by integrating NACS drivers without requiring adapters. However, EVs with CCS plugs will still need to use adapters.
The 750 kW is the theoretical maximum speed for future EVs capable of handling such power. Currently, the most advanced EVs can only manage up to 350 kW, with charging speed influenced by battery condition, temperature, and charge state. Many EVs are still limited to charging at around 150 kW.
Furthermore, most EVs increase their charging speed to an optimal point before slowing down as they near full capacity to protect the battery. This means it could take some time before vehicles capable of a 10-minute charge become mainstream.
Enhanced Features and Reliability
EVgo’s new stations are designed with an updated cable system for easier handling and a touchless payment interface. These chargers also include dynamic power sharing, which optimally distributes available power among connected vehicles, preventing any single vehicle from monopolizing the fast plug. Improved hardware and software are expected to enhance charger reliability, a critical feature for users who may find broken stations particularly frustrating.
Currently operating over 1,200 fast charging locations across the US, EVgo is designing and testing its next-generation system in El Segundo, California, with the support of partner Delta Electronics. The final design of the chargers is anticipated to be revealed in 2027, marking a significant deployment of new charging architecture.
