摘要： Coefficients A and B are calculated from the measured temperature and the measured state of charge. Next, a response voltage Vc is calculated by substituting the measured internal impedance X into a response-voltage correlation equation. Besides, by comparing the response voltage Vc with a predetermined threshold V0, if Vc is bigger than or equal to V0, the battery is determined as normal. By substituting the measured values of internal impedance, temperature, and SOC into the internal impedance calculation formula, a final internal impedance calculation formula is determined by calculating the value of C by an iterating operation. Next, in the case of determining SOH of a battery, by substituting a standard temperature and a standard SOC into the final internal impedance calculation formula, the internal impedance to determine the SOH is calculated. By comparing the internal impedance with SOH determination threshold, the SOH of the battery is determined.

摘要： A method and the device are provided for determining state of health of the battery, in addition to the power supply system using the device, to reduce operational and processing load by expanding the data sampled at the time when the battery is caused to discharge square wave pulses into the square wave is provided. The method includes determining state of health of a battery by causing the battery to discharge square wave pulses with a prescribed cycle at a prescribed current value. Response voltages are sampled at a time of a pulse-discharge. The sampled response voltages are sampled into orthogonal square wave components. An amplitude of the square wave component is divided by the current value of the pulse-discharge to obtain a pseudo-impedance. A state of health of the battery based on the pseudo-impedance is determined.
