Latest Patents

One of her latest patents is an energy storage device management apparatus and method. This invention utilizes a voltage measurement unit to detect the voltage of a secondary battery. It acquires the residual capacity from a correlation between the voltage and the residual capacity stored in memory. The state of charge (SOC) is then calculated as a ratio of the residual capacity to a reference capacity, which is set to a prescribed amount less than the full charge. Additionally, an information processing unit determines any abnormalities in the module by comparing the SOC with another method.

Another notable patent is for a positive active material for nonaqueous electrolyte secondary batteries. This invention aims to provide a positive active material that enhances cycle performance. It includes an Fe-containing lithium vanadium phosphate compound with a NASICON-type structure. The compound contains iron atoms that make up between 2% and 20% of the total of vanadium and iron atoms.
