Interoperable AC EV Charging Test Structure
Integrating AC/DC sources, simulators, and relevant signal generators, Chroma presents a complete EV charging compatibility test solution in accordance with major global standards. Through this test system, users can test EV by simulating global charging standards and environments.
AC EVSE Signal Emulator (80619)
- Sets the PWM signal input source of CP (Control Pilot) signal to either directly generate the PWM signal internally or input from an external signal generator.
- Allows setting voltage, frequency, and duty cycle of CP PWM signal.
- Simulates CC resistance signal output.
- Offers Enable signal with 12V and 24V output.
- AUX signal supplies 16 channels of 12V and 24V output.
- Presents box instrument control by single Ethernet port.
- Signal outputs are equipped with short circuits protection.
AC/DC EV Charging Control Unit
- Displays an integrated test interface for power and signal.
- The quick connect design provides standard charging couplers that can be easily switched according to specific test requirements.
DC EV Charging Compatibility ATS
DC charging pertains to fast charging; its voltage, current, and power are all higher than AC systems and it directly charges the power battery in the electric vehicle. Therefore, DC charging requires higher equipment specifications and communication technology. Chroma provides high-quality power electronics and charging test interfaces compatible in various countries to fully support all testing needs.
DC EV Simulators
CCS DC EVSE Simulator
- Simulates PLC communication for electric vehicles and supports testing of ISO 15118, DIN 70121/22 and other communication standards.
CHAdeMO EVSE Simulator
- Compliant with CHAdeMO regulations, can simulate the charging station as well as the charging process for DC EV testing.
- Simulator supports CHAdeMO 0.9/1.0/1.1 test regulations.
- CAN1 supplies CAN Data to monitor the simulator and EVSE.
Communication Interface Emulator (80618)
- Communicates with the Chroma 8000 software system through the Ethernet interface.
- Provisions a total of four channels CAN bus that support CAN 2.0B (29-bit) arbitration ID.
- Following GB/T 27930 regulations, the multi-core data refers to the SAE J1939 communication protocol and provides records of message transfer and reception time.
- Each unit supports a set of one RS-232 and one RS-485.
- 16 DIs and 16 DOs use a dry contact mode that controls DO and reads DI statuses through the system software or uses the GB/T 27930 function to control DO output when sending/receiving data.
- Connects to A806110 through Ext-BU, each unit has two I2C and SMBus communication interfaces. I2C can support the role of slave, while I2C clock can be 1MHz (port 1) or 400kHz (port 2).
