AC EVSE ATS
AC charging stations work with the on-board charger (OBC) on the EV, in order to charge the power battery after AC/DC conversion.
Chroma's AC EVSE ATS is equipped with a variety of power output and communication interfaces that can test products with different powers, communication protocols, and specifications.
AC EVSE Control Unit
- Simulates the EV charging circuit through AC EVSE tests: charging stages simulation, leakage current, ground open circuit, Control Pilot (CP) signal open circuit/ground short circuit, Connection Confirm (CC) signal open circuit, abnormal resistance simulation, etc.
- Supports three types of AC charging couplers, compliant with SAE J1772, IEC 62196, and GB/T 20234
- RB/RC resistor simulation and CP signal test
- Offers trigger sync signal channels: StateB, StateC, StateD, Sync1, and GND_Sync
- Optional NACS AC charging socket fixture
DC EVSE ATS
DC chargers pertain to fast charging; their voltage, current, and power are all higher than AC systems and they directly charge the power battery in the electric vehicle. Therefore, DC chargers require 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, NACS, GBT, ChaoJI EV Communication Simulator (80713 & 80701)
- Simulates vehicle-side charging circuits: simulates charging process, leakage current testing, ground fault testing, CP/CC signal abnormality testing, simulated abnormal resistance testing, etc.
- PLC communication simulation, supports ISO15118-4/-5/-20, DIN70122
- CAN communication simulation, supports GB/T 27930
- Provides transmission and reception data time recording for communication protocols
- Can simulate scenarios involving charging multiple EVs
- Trigger signal channels: StateB, StateC, StateD, Sync1, GND_Sync
DC CHAdeMO EV Simulator
