What are you looking for?
We strive to build a charging management system (abbreviation: CCU), which is the core monitoring equipment of the non-vehicle DC charger system, complies with industry standards and meets market demand. It mainly realizes control guidance, vehicle communication, DC side sampling and control, and communication with human-machine interface, etc.
Realize communication with human-machine interface
Realize communication with power management system (PCU)
Realize communication with intelligent management unit (IMU)
Detect charging gun connection status
Collect positive and negative pole temperature of charging gun
Bus voltage collection and insulation detection
Battery voltage collection
Charging current collection
Charging gun seat status detection
Electronic lock status detection and control
Emergency stop, access control and other switch status detection
Discharge relay control
