Charge control is a technology that lets an electric utility control, in real time, the charging of a griddable (plug-in) vehicle, such as a plug-in hybrid (PHEV) or a battery electric vehicle (BEV). Through charge control, the utility is able to postpone charging of the vehicle during time of peak demand.


For example if you want to enable Level 3 DC Fast Charging on your vehicle, you will need to communicate with the Electrical Vehicle Supply Equipment (EVSE) over one of the standard protocols such as ISO15118/DIN70121, GB/T, or CHAdeMO. The EVCC manages this communication protocol as well as controls the flow of energy between the EVSE and the battery.


  • CC613 is the latest EV charge controller to be released from Bender. It incorporates a range of upgraded features and benefits enabling the manufacture of safe, connected, compliant charge stations, actively controlling, monitoring, authorizing and billing the entire charging process in accordance with to IEC 61851-1.
    • CC613 features an integrated Ethernet interface, which allows direct and easy integration of the controller into an existing Ethernet network. The Ethernet interface now provides a direct and convenient way to set up a networked charging infrastructure that can be easily maintained and controlled remotely. A further innovation is the integrated emergency opener. In the event of a power failure, the emergency opener unlocks the charging connection at the charging station so that the charging plug can be removed safely. The advantage is that no additional components are required for plug release or wiring, which reduces costs and allows a more compact charging station or wallbox design.
  • Argonne has developed a “smart” frequency-based charge controller (FBCC) system for electric vehicles and a method for implementing demand response and regulation services to power grids. As plug-in hybrid electric vehicles and battery electric vehicles become more popular, they create additional demand for electricity. Their emergence also raises a host of issues regarding how, where and when car batteries should be charged—and the resulting load on the power grid.
    • Argonne’s system uses frequency-sensing charge controllers that provide automatic demand response and regulation service to the grid by reducing or turning the charging load completely off if the system frequency falls below a given threshold, and turning it back on after the balance of supply and demand has been restored. The system minimizes the burden on the power grid and provides significant benefits to electric utilities by providing a frequency-responsive load.
  • Siemens also develops charge controllers which enable any vehicle to be charged at any voltage, is an easily programmable technology, provides consulting and engineering services for them.
