In developing standard software modules for charger controllers in electric vehicles, Vector extends the Microsar IP stack by adding protocols for smart charging communication. Smart charging requires a communication channel between the charging station and the vehicle. The channel is used to exchange information for the charging process and for electrical accounting and may be implemented by an internet connection (IP) over the power cable. Additional contacts in the plug are avoided, and data transmission rates of up to 200 Mbit/s are possible. For Vector's smart charging implementation, the charger controller contains an IP stack for handling protocol communication with the charging station, and the controller features a CAN stack to apply the interface to the vehicle’s existing network, such as power management or instrument cluster. Internet protocols are also available.
