Mona Inc. provides a complete battery diagnosis system, a combination of hardware and software, that quickly and accurately examines cells/modules/packs and detects defects and abnormalities in the batteries. We implemented artificial intelligence into equipment that measures EIS (Electrochemical Impedance Spectroscopy) and battery capacity through charge discharge. With the extensive data collected by the equipment and artificial intelligence, we believe that battery-related accidents such as thermal runaways could be significantly reduced and, therefore, safer and more secure EV experiences.
