ISO 15118 and DIN 70121 Handshake Problems: What Engineers Should Check First

Troubleshooting handshake issues in direct current (DC) charging systems is essential for ensuring that electric vehicles (EVs) and charging stations communicate effectively. Handshakes form the backbone of this communication, allowing for the establishment of secure links that facilitate charging interoperability. Engineers must perform systematic checks when faced with handshake problems, starting with the fundamental communication layers. Inspecting physical connections and ensuring that the connector is optimally seated in the vehicle can resolve many initial issues, while using an oscilloscope to verify signal integrity can identify potential malfunctions in the transmission.
