Hyundai Motor Company Receives Patent for Advanced Battery Diagnosis System

Strategic Insights

— 2 min read

Hyundai Motor Company has been granted a patent for its innovative battery diagnosis system, designed to detect potential faults in high-voltage batteries of electric vehicles. The patented system utilizes a unique approach to diagnose abnormal battery cells by analyzing the changes in polarization voltage during a temporary charging stop state. This advanced system can identify potential faults in advance, preventing unexpected issues and ensuring the safety of high-voltage components.

The battery diagnosis system comprises several key components, including a receiving unit, a control unit, a measurement unit, and a determination unit. The receiving unit collects information on the high-voltage battery and its charge state, while the control unit regulates the current flow to the battery. The measurement unit measures the voltage change amount of the battery, and the determination unit analyzes the data to identify abnormal battery cells. The system can also determine the deterioration degree of the battery by calculating the resistance value of the battery.

The patented system allows for real-time diagnosis and monitoring of battery health, enabling early detection of potential issues and preventing safety accidents. Hyundai Motor Company's advanced battery diagnosis system is a significant step forward in electric vehicle technology, ensuring the reliability and safety of high-voltage batteries.
