EVgo is preparing for the next generation of electric vehicles with a new high-power charging architecture capable of delivering up to 750kW of charging power.
The fast-charging company has begun designing, developing, and testing the new system at its Innovation Lab in El Segundo, California, with support from longtime technology partner Delta Electronics. EVgo says the architecture is designed to handle rising charging speeds as automakers introduce EVs with larger batteries and more advanced charging capabilities.
The company expects to reveal the final charger design in 2027, when deployment of the new charging architecture is also scheduled to begin.
EV charging speeds have increased significantly as newer electric vehicles arrive with improved battery technology and higher charging capabilities. EVgo says charging rates across its network have increased by nearly 20% over the past two years, a trend the company expects to continue.
Its new 750kW architecture is intended to prepare the network for that growth.
EVgo CEO Badar Khan said the company has spent more than 15 years serving EV drivers and that the new architecture is designed to future-proof its charging network as charging demand increases.
The system is expected to support the fastest-charging EVs currently available in the U.S., with EVgo estimating that compatible vehicles could add a substantial amount of range in around 10 minutes, depending on the vehicle and its charging capabilities.
The 750kW figure does not mean every EV will charge at 750kW. Actual charging speeds will continue to depend on each vehicle’s battery, charging system, state of charge, temperature, and other factors.
One of the most important features of EVgo’s new charging architecture is dynamic power sharing.
Instead of requiring drivers to find a charging stall capable of delivering a specific power level, the system can automatically distribute available electricity between dispensers based on what each vehicle needs.
The architecture continuously adjusts power delivery throughout a charging session. That could become increasingly important as the gap between charging capabilities widens among different EV models.
For example, one vehicle may be capable of accepting significantly more power than another. Rather than assigning fixed power levels to individual stalls, EVgo’s system can dynamically route available energy to where it is needed.
The technology could also help manage demand on the electrical grid by allowing charging power to be allocated more flexibly and helping smooth demand spikes.
EVgo says the new hardware has been developed using data from its growing customer base, which includes approximately 1.8 million customer accounts and more than 10 million charging sessions annually.
The next-generation chargers are being designed with several changes aimed at making public charging easier and more convenient.
Among them are improved cable maneuverability and a touchless payment interface. EVgo is also developing new hardware and firmware intended to improve charger reliability and simplify the overall charging experience.
Every charger in the new architecture will feature NACS connectors, reflecting the growing adoption of the North American Charging Standard across the U.S. EV market.
The move is part of EVgo’s broader strategy to expand access to its network as more electric vehicles adopt NACS charging ports.
Another notable aspect of the project is that EVgo is developing the charger architecture itself rather than relying entirely on an outside charging-equipment manufacturer.
With support from Delta Electronics, EVgo is carrying out the design, development, and testing of the system at its California Innovation Lab.
The company says this makes EVgo one of a small number of American charging networks developing its own charging hardware architecture.
That level of control could allow EVgo to integrate charger hardware, software, power management, and customer-facing features more closely as charging technology continues to evolve.
The arrival of higher-power EVs is putting increasing pressure on public charging networks to provide faster and more flexible charging infrastructure.
EVgo’s 750kW architecture is designed with that transition in mind. While today’s EVs generally cannot use the full 750kW output, future vehicles could make greater use of higher-power charging as battery and thermal-management technology improves.
The final design is expected to be unveiled in 2027, followed by deployment of the new charging architecture.
For EV drivers, the most important change may not simply be the headline 750kW figure. Dynamic power sharing, NACS availability, improved cable design, touchless payments, and greater charger reliability could ultimately have a bigger impact on how quickly and easily drivers can charge on long-distance trips.
