METHOD AND APPARATUS FOR DETECTING BATTERY STATE OF CHARGE |
摘要 |
A method for detecting the charged state of a battery based on the measurements of open circuit voltage in which the charged state of a battery can be detected precisely regardless of the degradation state of the battery. Internal impedance of a battery is measured, voltage of the battery is measured under stable state, measurement of the battery voltage under stable state is subjected to raising correction depending on the measurement of internal impedance, and then charged state of the battery is determined based on the corrected value of battery voltage under stable state.
