Securing Tomorrow's Drive: A Sneak Peek into the Safety Measures of Electric Vehicles

As electric vehicles (EVs) continue to revolutionize the automotive industry, ensuring the safety of their power source, the battery, is paramount. In this article, we delve into a sophisticated yet practical approach to bolstering battery safety. Our focus is on the application of predictive diagnostics, a strategic method that empowers battery operators to address safety concerns proactively, preventing potential damage.

At the forefront of our safety strategy is OXRED's innovative concept of the Safety Index. This parameter, ranging from 0 to 1, quantifies the safety level of the battery, with 1 signifying absolute safety and 0 indicating an unsafe state. The Safety Index function, a pivotal component, intricately calculates the end safety result.

Breaking down safety into three distinct facets—Electrical, Physical, and Chemical—allows for a comprehensive assessment. Electrical safety hinges on voltage and current patterns, while Physical safety is contingent on temperature variations. Chemical safety, the third dimension, involves monitoring self-discharge rates and internal resistance. The figure below shows the Safety Index representation along the three distinct facets.

The Safety Index functions generate specific safety values for each category, creating a nuanced understanding of the battery's safety profile. Subsequently, an overall safety variable is derived, offering a holistic perspective on the battery's safety status.

The beauty of predictive diagnostics lies in its foresight. By identifying potential safety concerns at an early stage, operators can take timely actions to avert any adverse outcomes. This strategic approach not only safeguards the longevity of the battery but also contributes to the overall reliability of electric vehicles.

Embracing such sophisticated yet practical methodologies ensures that electric vehicles continue to lead the way in sustainable and secure transportation.
