BATTERY MANAGEMENT APPARATUS |
| 摘要 |
A battery management apparatus to manage a battery in a vehicle includes a temperature detector that detects a temperature of the battery, a current detector that detects a current of the battery, a calculation unit that calculates a first degradation capacity using the detected temperature of the battery at every unit time while the vehicle is driven and that calculates a second degradation capacity using the detected temperature and state of charge (SOC) of the battery at every unit time while the vehicle is parked, and a determination unit that calculates a state of health (SOH) of the battery using the first and second degradation capacities so as to determine a replacement time of the battery according to the calculated SOH. |
