Electric Vehicle Test System

Electric Vehicle Charging Compatibility ATS

Chroma C8000

The world’s first UL approved SAE J1772 EVSE Communication Protocol Automated Test System. This system simulates various states of an EVSE to validate charging compatibility before delivery to the vehicle.

The Chroma C8000 Auto Test System uses a unique test command optimization technology to prevent sending repetitive control commands to the system hardware devices. This improves system test speed dramatically and makes the Chroma 8000, which uses open software architecture, highly efficient as a closed or optimized auto test system.

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
  • 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
  • Quick-connect design provides standard charging couplers that can be easily switched according to specific test requirements
DC EV Charging Compatibility

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 the 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.

CCS DC EVSE Simulator

Simulates PLC communication for electric vehicles and supports testing of ISO15118, DIN70121/22 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

  • Communicates with the Chroma 8000 software system through the ethernet interface
  • Provisions a total of four channels CAN bus that supports CA 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 16DOs 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 12C and SMBus communication interfaces. I2C can support the role of slace, while I2C clock can be 1MHz (port 1) or 400kHz (port 2)
Global Test Standards

Chroma provides test systems that support relevant international test items to assist users in exalting their products to the international stage. Chroma 8000 achieves testing of all major global test standards, including SAE, CNS, NB/T, GB/T, ISO, IEC, DIN, and CHAdeMO.

PowerPro's Certificate Management Tools for Optimal PnC EVSE Testing

Chroma’s PowerPro 5 software, part of this comprehensive EV test system solution, features a Certificate Management Tool that allows users to load specific certificate files (*.p12, *.pem). Using designated OEM agreements and contract certificates, the software automatically performs public/private key encryption and decryption during the test to achieve the handshake and payment processes required for ISO 15118 PnC testing. Additionally, it can simulate signature modification, encryption mismatch, invalid EMAID (eMobility Account ID), and other errors for more advanced PnC tests. This solution provides a fast, convenient, comprehensive test platform for validating PnC functionality in EVs and EV supply equipment (EVSE).
