Electric vehicle (EV) fast charging technology is evolving rapidly, with next-generation chargers offering increased power and power-sharing capabilities to serve more drivers efficiently.

Simultaneous charging allows a single charging dispenser to share power between its connectors, enabling two drivers to charge their vehicles at the same station simultaneously. This technology increases station efficiency and expands access to fast charging while using less equipment.

How Simultaneous Charging Works

When one vehicle uses a 350kW simultaneous charger, it can access the full power capacity. When two vehicles connect, the power splits equally, providing up to 175kW per vehicle - enough to add 100-150 miles of range in 15 minutes for compatible vehicles.

Advanced chargers, like Signet units deployed by EVgo, can dynamically share power between dispensers in 25kW increments, offering flexible power distribution options.

How to Identify Simultaneous Chargers

Look for:

• "Simultaneous Charging Available" message on the charger screen
• Double arrow symbol next to 350kW chargers in the EVgo app

Checking Connector Availability:

• Green icons indicate available connectors
• Red icons show connectors in use

Charging Display Information:

• Single user: Up to 350kW available
• Shared session: Up to 175kW per vehicle

This technology allows charging stations to serve more vehicles efficiently while preparing for future EV charging demands. The system's dynamic power sharing ensures optimal power distribution based on vehicle capabilities and charging needs.
