optoCharger™ Bidirectional Optical Transmission System for CCS, CHAdeMO, GB/T

Overview

The optoCharger™ is a battery powered, bidirectional optical interface designed to isolate and transmit communication signals between an Electric Vehicle Supply Equipment (EVSE) charging station and an Electric Vehicle (EV) during EMC/EMI testing. Its fiber optic link and shielded aluminum enclosure make it ideally suited for high noise environments—compliant with CISPR 25 Class 5 requirements—ensuring measurement integrity and operator safety.

Key Features

Bi Directional Optical Link
Transmits Control Pilot (PLC), CAN, low level signals, and auxiliary lines (e.g. temperature monitoring, connector lock) across a 20 m multimode fiber.
Integrated Battery Power
Seven NiMH cells (8.4 V, 4 Ah) deliver approximately 10 hours of run time; extendable via external battery pack.
Rugged, Shielded Housing
Anodized aluminum enclosure with rubber bumpers, grounding lug, and stacking capability (140 × 86 × 65 mm).
Universal Charging Standards
Supports CCS, CHAdeMO, and GB/T protocols for broad compatibility.
Simple Connectivity
BNC connector for Control Pilot, D SUB 15 female for all other signal lines, plus optional FSMA optical connector.

Applications

Automotive EMC immunity and emissions testing (e.g. CISPR 25 Class 5)
On site and laboratory validation of EV/EVSE communication interfaces
Any test scenario requiring galvanic isolation and high?noise immunity
