Latest Patents
One of Ryushiro Tokunaga's key patents is focused on a secondary battery system and a state of charge (SOC) estimation method for secondary batteries. The patent describes an electronic control unit (ECU) that executes SOC estimation control to accurately estimate the SOC of a battery. The ECU obtains a 'first voltage' that indicates the open-circuit voltage (OCV) of the battery during the SOC estimation process. It controls an engine and a power control unit (PCU) to ensure that the battery is charged with an amount of electric power that meets or exceeds a prescribed threshold when the first voltage falls within a specific hysteresis range. Additionally, the ECU measures a 'second voltage' that reflects the OCV of the charged battery and uses this information to estimate the SOC.
