AI Technical Summary

Technical Problem

The existing battery connectors for eCall systems in vehicles are prone to malfunction due to the ground (GND) pin not making contact first, leading to electrical fluctuations and battery management IC failures during connection with external devices.

Method used

The battery pack connector is designed with the (-) pin protruding beyond the (+) pin, ensuring it makes contact first with the external device connector, and includes a conductive plate structure with varying pin lengths to establish a stable electrical connection.

Benefits of technology

This design prevents ground wire contact issues, stabilizing the battery connection and preventing battery management IC malfunctions by ensuring the (-) pin contacts before the (+) pin, enhancing the reliability of the eCall system.
