EV Simulator for CCS EVSE Development
SECC TD is an EV Simulator embedded with the common charging sequences for the communication between EV Charger and Electric Vehicle (EV) in accordance with DIN SPEC 70121, and ISO 15118.
SECC TD is an economically efficient product, which includes EVCC and BMS Simulator to get the accurate correspondence without Electric Vehicle.
On the LCD display, the user can monitor real-time EV charging sequence without connecting PC program. This device is also best fit for testing communication in the maintenance and product inspection as well as developing of the EV Charger.
The user can check the following data in each charging sequence:
- PWM signaling based on IEC 61851 (CP duty, CP voltage)
- SLAC sequence for PLC association of HomePlug Green PHY standard
- HLC (High Level Communication) of charging protocol for data communications
