The difference between the male and female sides of an EV charging cable plug lies primarily in their intended connection points and technical design. The male side of the cable, often referred to as the charging station plug, is the end that connects to the EV charging point or wallbox. This side typically has exposed pins that deliver power and communication signals. The female side, commonly called the vehicle connector, is designed to plug into the electric vehicle's charging port and features recessed contacts to enhance safety.

Both sides conform to international standards like IEC 62196-2 (commonly known as Type 2 in Europe), but their configuration and purpose are not interchangeable. The female vehicle connector includes several safety mechanisms such as proximity detection and locking pins, which ensure a secure and tamper-proof connection with the car. In contrast, the male plug lacks these vehicle-specific features but is optimized to fit the infrastructure side of the charging interface.

This male/female distinction is also critical for regulatory and safety reasons. It prevents users from connecting two cables together to create an unauthorized extension, which could lead to overheating, communication errors, or electrical hazards. By ensuring the cable only connects from the station to the car in one direction, the EV charging system maintains proper current flow, grounding, and handshake protocols, which are essential for safe and efficient charging.
