Rabat – Moroccan scientist Rachid Yazami was granted a new patent in China for his work on lithium battery technology, specifically the fast-charging technique.
The Moroccan innovator took to social media this weekend to announce the news. “Proud to share that after Japan last February, it is now China’s turn to grant us a patent for the fast-charging method for batteries, particularly for future electric cars,” he said on Facebook.
The invention patent certificate is titled “Adaptive Charging Protocol for Fast Charging of Batteries and Fast Charging System Implementing this Protocol.” The patent was filed in December 2018.
“Having examined the present invention in accordance with the Chinese Patent Law, this office has decided to grant the invent patent, issue this certificate, and record it in the register,” the certificate reads. The patent right has come into force from November 15, 2024.
Yazami received the first patent from the Japanese Patent Office in February this year. His invention, known as the “Non-Linear Voltage” technique, focuses on faster charging for lithium batteries used in both electronic devices and electric vehicles.
Traditional methods of charging lithium batteries often take at least 30 minutes to charge from 20% to 80%. However, his new technique optimizes the management of electrical current in the battery rather than focusing solely on its voltage.
Speaking to Morocco World News at the third edition of the Global Industry 4.0 Conference last year, Yazami said that “this is a revolutionary method that we have tested on a large variety of batteries and especially batteries for electric cars, scooters, and cordless power tools.”
He noted that the method “works very well…We are cutting the charging time by a factor of two, three, or four, depending on the batteries.”
Recent experiments by Yazami and his team in Singapore, where he is based, have achieved remarkable results, fully charging a battery in just 15 minutes. In some tests, they even managed to charge a battery in as little as five minutes, setting a new record for charging speed.
The news comes as Morocco has been charging up its efforts in the renewable energy sphere, and international partners – particularly China – are taking part. Recently, Chinese battery giant Gotion High-Tech announced plans to allocate €1.28 billion toward the development of a cutting-edge lithium battery production facility in Morocco, a key development in the growth of this sector.
