Moroccan scientist Rachid Yazami patents innovative battery safety technology

Moroccan scientist Rachid Yazami has recently secured a pivotal patent from the U.S. Patent and Trademark Office (USPTO) for a novel method designed to detect early signs of internal short circuits in batteries. This advancement holds significant implications for the safety of electric vehicles (EVs), addressing one of the foremost risks associated with battery technology.

The patented method focuses on identifying the hazardous phenomenon known as thermal runaway, which can lead to catastrophic fires or explosions in EVs. Yazami announced this breakthrough on social media, sharing details of the patent that outlines a system based on real-time analysis of thermodynamic and kinetic data from electrochemical cells.

In his communication, Yazami expressed his excitement about the invention, stating, “This relates to the premature detection of an internal short circuit in a battery, which is the main cause of thermal runaway.” He emphasized the potential of this technology to save lives by mitigating one of the critical dangers linked to battery operation.

The innovative system monitors key parameters such as open-circuit voltage, entropy, and enthalpy variations. By doing so, it can identify early indicators of internal short circuits, allowing for timely preventative measures before any dangerous incidents occur.

As the global adoption of electrification in transportation accelerates, this patent marks a substantial step forward in enhancing battery safety for electric vehicles. Speaking to Morocco World News (MWN) at the Global Industry 4.0 2023 event in Casablanca, Yazami highlighted the necessity for batteries to be adapted to the unique environmental conditions of the market, where temperatures can soar above 50 degrees Celsius.

This achievement underscores Yazami’s enduring commitment to advancing the reliability and safety of energy storage systems. The patent was initially filed on May 28, 2019, and complements his recent achievements in battery safety technology.

Earlier this year, Yazami received a similar patent from China, aimed at minimizing the risk of fires or explosions in EV batteries. He also holds a patent for fast-charging technology for lithium batteries utilized in both consumer electronics and electric vehicles.

Yazami’s innovations are closely aligned with Morocco’s strategic shift toward greener energy solutions, reinforcing the country's dedication to renewable energy initiatives that contribute to the global fight against climate change.
