Abstract: This disclosure provides an estimation method applied to a state of health of a battery, which executes a recharging to a battery when a battery voltage is lower than a threshold voltage. During the recharging, a battery state of health estimation procedure is performed from a first depth of discharge detection point to a second depth of discharge detection point. During the battery state of health estimation procedure, a voltage difference between a current battery voltage and an initial open-circuit voltage is accumulated over time from the first depth of discharge detection point to the second depth of discharge detection point to obtain an accumulation of current sampled voltage difference. An accumulation of estimated DC internal resistances can be equivalently obtained by the accumulation of current sampled voltage difference. Afterwards, the state of health of the battery can be determined based on the accumulation of estimated DC internal resistance.
