STATE-OF-CHARGE ESTIMATING DEVICE, STATE-OF-CHARGE DETERMINING METHOD, AND STATE-OF-CHARGE DETERMINING PROGRAM |
| 摘要 |
A state-of-charge estimating device includes an open-circuit voltage estimating part, a map selecting part, and a state-of-charge estimating part. The open-circuit voltage estimating part estimates an open-circuit voltage of a secondary battery. The map selecting part selects a map indicating a relationship between a first open-circuit voltage and a state of charge of the secondary battery, based on the first open-circuit voltage of the secondary battery fully charged. The state-of-charge estimating part estimates the state of charge corresponding to a second open-circuit voltage after estimating the first open-circuit voltage, based on the selected map. |

1. A state-of-charge estimating device comprising:
an open-circuit voltage estimating part that estimates an open-circuit voltage of a secondary battery; a map selecting part that selects a map indicating a relationship between a first open-circuit voltage and a state of charge of the secondary battery, based on the first open-circuit voltage of the secondary battery fully charged; and a state-of-charge estimating part that estimates the state of charge corresponding to a second open-circuit voltage after estimating the first open-circuit voltage, based on the selected map. |
