Data Sheets

Perform Seamless Observation of the CCS Communication Channel between EV and EVSE

The Keysight SL1556A CCS Charging Protocol Tracer (CCS Tracer) enables seamless observation of the CCS communication channel between a charging station (EVSE) and an electric vehicle (EV). In combination with SL1487A CCS Charging Protocol Trace Viewer (CPT), the user can analyze the overthe-wire communication traffic, which is communicated via HomePlug Green PHY Powerline Communication (HP GP PLC) on the Control Pilot (CP) Line.

The CCS Tracer integrates a HomePlug Green PHY (HP GP) MAC/PHY according to DIN SPEC 70121:2014 and ISO/IS 15118-3:2015 as well as CP signal detection circuitry for IEC 61851-1:2017 Ed 3. The observed data is available via an Ethernet Bridge. The CCS Tracer provides a non-invasive test interface for direct coupling to the Control Pilot (CP) and Protective Earth (PE) lines. Alternatively, the SL1556A-001 Inductive Cable Clamp also provides an option for inductive coupling, e.g. for field tests between real EVs and EVSEs.

Feature Overview

Feature	Description
Operating modes	(1) Passive Sniffer (PLC to Ethernet Bridge) via Inductive Cable Clamp (SL1556A-001) (2) Passive Sniffer (Control Pilot PWM/PLC to Ethernet Bridge) via direct coupling (SL1556A-002)
Observation of CP according to IEC 61851-1:2017 Ed. 3	PWM detection (configurable) • Frequency (Hz), duty cycle (%) and voltage (mV) • Note: Direct coupling is required.
HomePlug Green PHY V1.1.1 PLC Sniffer	HP GP packet sniffing (Layer 2 MMEs) • DIN SPEC 70121:2014 • ISO/IS 15118-3:2015
Casing	Robust metal case

Front/Rear Panel and Interfaces

With the CCS Tracer, you can tap on the charging cable between EV and EVSE via conductive or inductive coupling over the XLR industrial-grade 3-pin female connector on the front panel. The connection to the data logger or test host is provided via a XLR industrial-grade RJ-45 Ethernet socket (100Base-TX). The wide range 6~48 V DC input socket is based on an industrial-grade 3-pin XLR male connector.

Inductive Coupling Unit

The SL1556A-001 Inductive Cable Clamp enables capturing trace files between CCS EV and EVSE.
