According to information from the China National Intellectual Property Administration, ABB E-Mobility Ltd. has filed a patent titled “Controller Unit for Controlling Electric Vehicle (EV) Supply Equipment (EVSE), EVSE, EV Charging Infrastructure, and Method for Controlling EV Charging Infrastructure,” with publication number CN121340973A, submitted in July 2025.

The patent abstract describes a controller unit designed to manage EV supply equipment (EVSE) used for electric vehicle charging. The controller integrates one or more hardware modules dedicated to charging functions and uses a processing unit to enable intelligent system control.

The controller is configured to detect one or more hardware modules within the EVSE and determine the system configuration based on the detected components. This configuration data reflects the specific hardware setup of the charging equipment.

Based on the identified configuration, the controller dynamically generates an appropriate control strategy. The system includes a memory storing multiple control routines, and selects suitable routines according to the detected configuration to form the final control scheme.

In addition, the controller supports installation and updates of control routines via a network interface, enabling continuous optimization of system functionality. The EVSE is then operated based on the dynamically determined control strategy, allowing adaptive and flexible management of charging infrastructure.

This approach enhances the intelligence and adaptability of EV charging systems, improving operational efficiency and supporting more scalable charging infrastructure deployment.
