The battery manger (50) includes a voltage measurement component (70), a current measurement component (80), and a controller component (60). The voltage measurement component (70) is configured to measure a voltage across the secondary battery (30). The current measurement component (80) is configured to measure a current flowing through the secondary battery (30). The controller component (60) is configured to, when estimation of state of charge of the secondary battery (30) based on an accumulated amount of current measured by the current measurement component (80) is defined as a current accumulation method and estimation of state of charge of the secondary battery (30) based an an open circuit voltage (OCV) of the secondary battery (30) measured by the voltage measurement component (70) is defined as an OCV method, permit estimation of state of charge by the OCV method when a condition that an error in estimation of state of charge of the secondary battery (30) by the current accumulation method exceeds an error in estimation of state of charge of the secondary battery (30) by the OCV method is satisfied.",
