The CA 6652 from Chauvin Arnoux is a test adapter for AC charging stations with Type 2 connection, specifically developed for the diagnosis, commissioning, maintenance, and testing of electric vehicle charging infrastructures (EVSE). It serves as a tool for professionals in the field of electrical installation, maintenance services, inspection authorities, and educational institutions. The adapter enables the simulation of various vehicle states and fault conditions to verify the functionality and safety of charging stations in accordance with applicable standards.

Applications

The CA 6652 is designed for testing charging stations operating in Mode 3 (Ladebetriebsart 3), used in private low-voltage installations with Type 2 connection points. It is employed during commissioning, maintenance, fault diagnosis, re-testing, and training on charging infrastructure. The device can be used both indoors and outdoors, with protection rating IP 54 enabling use under normal outdoor conditions. The operating temperature range is from -20 °C to +55 °C, and the storage temperature range is from -20 °C to +70 °C.

Functions and Equipment in Detail

The adapter simulates the state of an electric vehicle by simulating the PP status (Proximity Pilot) in stages: Not connected (NC), 13 A, 20 A, 32 A, and 63 A, as well as the CP status (Control Pilot) in states A, B, C, and D. Additionally, fault conditions such as CP-PE short circuit, diode short circuit CP-PE, and PE interruption can be simulated. These functions are used to check the charging station’s response to fault conditions and safety features such as automatic disconnection in case of failure.

Technology Explained Simply

The CA 6652 features 4 mm test sockets for L1, L2, L3, N, PE, and the CP signal, allowing direct connection of measuring instruments. The LED display indicates applied voltages, facilitating visual inspection of the power supply. A touch electrode detects hazardous voltages on the protective earth conductor PE and signals this optically to ensure operator safety. The cable length is approximately 60 cm, the housing dimensions are 221 x 100 x 44 mm, and the weight is 850 g.

Compatibility and Accessories

The adapter is designed for use with multifunction installation testers, voltage testers, continuity testers, insulation testers, earth testers, FI/RDC testers, loop resistance meters, and rotation direction indicators. Communication issues between vehicle and charging station can be analyzed using oscilloscopes such as HANDSCOPE II or SCOPIX IV BUS, with the CP signal directly accessible at the test sockets of the CA 6652. The standard IEC 60364-7-722 requires testing of electrical safety aspects, which are supported by the CA 6652.

Mounting and Installation

The CA 6652 is directly connected to the charging station by inserting the Type 2 plug into the station’s charging socket. Measuring and testing instruments are connected to the 4 mm test sockets. Operation is performed via rotary switches for CP and PP status, and buttons for fault simulation. Installation requires no additional tools or mounting components.

Advantages in Operation

The CA 6652 enables fast and comprehensive diagnosis of charging stations. The simulation of various vehicle states and fault conditions allows testing of safety functions and communication between vehicle and charging station. The visual voltage indication and touch electrode enhance operator safety. Compliance with standards IEC/IEC 61010-2-030 (adapter) and IEC/EN 61010-2-031 (test lead, 300 V CAT II, pollution degree 2), as well as EMC conformity according to IEC/EN 61326-1, ensures the reliability and safety of the device. The IP 54 protection rating allows outdoor use, while IP 40 applies for indoor use.
