  "textContent": "A remaining battery energy estimation device according to an embodiment includes a current corrector, an SOC calculator, a voltage estimator, an SOC correction amount determiner, and a current error estimator. The current corrector determines a corrected current value on the basis of a current value and a current correction amount of a storage battery. The SOC calculator calculates an estimated SOC value of the storage battery on the basis of the corrected current value and an SOC correction amount. The voltage estimator determines an estimated voltage value of the storage battery on the basis of a temperature value of the storage battery, the corrected current value, and the estimated SOC value. The SOC correction amount determiner determines the SOC correction amount on the basis of a comparison between a voltage value of the storage battery and the estimated voltage value. The current error estimator determines the current correction amount on the basis of the SOC correction amount.",
