| description | A secondary battery state detection device for detecting the state of a secondary battery includes at least one processor and at least one memory that is communicably connected to the at least one processor. The at least one processor reads a set of instructions stored in the at least one memory, and executes detection processing in which a charging voltage is detected, the charging voltage being generated when an alternator that generates an adjustable voltage charges the secondary battery; computation processing in which a charging resistance is computed as an internal resistance of the secondary battery when the alternator charges the secondary battery; and estimation processing in which a state of charge of the secondary battery is estimated on the basis of the charging voltage detected by the detection processing and on the charging resistance computed by the computation processing. |
