Abstract: The invention presents a method for estimating a direct current internal resistance of a battery, which defines a depth of discharge detection interval including a first threshold and a second threshold. When the battery is discharging, a currently battery voltage are periodically measured, a currently depth of discharge is calculated, and an open-circuit voltage is queried. The currently battery voltage is subtracted from the open-circuit voltage to obtain a voltage difference. The voltage difference is continuously accumulated to obtain a currently accumulated voltage difference. The currently depth of discharge reaches the first threshold or the second threshold, the currently accumulated voltage difference is a first accumulated voltage difference or a second accumulated voltage difference.

Abstract: A glass ceramic is provided to address the challenge that bioceramics known to be used for bone defect repair often lack good hardness, proper degradability, low post-implantation stimulation to surrounding tissues and promotion of bone defect repair in combination. The glass ceramic comprises a major crystallized phase, which is either diopside or wollastonite; and a minor crystallized phase, which comprises any one or more selected from the group consisting of diopside, wollastonite, lithium disilicate, silicon dioxide, lithium metasilicate and Li2Ca2Si5O13. In the glass ceramic, the molar ratio of elemental calcium, elemental lithium and elemental silicon is 1:x:2, in which x is from 0.05 to 1. However, when the major crystallized phase is diopside, the minor crystallized phase does not comprise diopside; and when the major crystallized phase is wollastonite, the minor crystallized phase does not comprise wollastonite. The present invention also comprises a method for manufacturing the glass ceramic.

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.
