摘要： In one embodiment, a depassivating circuit includes a battery, a resistive load coupled to the battery, and a magnetic field sensor. The magnetic field sensor detects a presence of a magnetic field. The magnetic field sensor depassivates the battery by causing current from the battery to flow through the resistive load, in response to the presence of the magnetic field. The magnetic field sensor detects removal of the magnetic field. The magnetic field sensor ends depassivation of the battery, in response to the removal of the magnetic field.

摘要： A battery system is configured to estimate a presence or absence of deterioration of a battery. This deterioration is a phenomenon in which an internal resistance of the secondary battery increases due to uneven ion concentration in a non-aqueous electrolyte. The battery system includes a voltage sensor and an ECU. The voltage sensor detects a voltage value of the battery. The ECU is configured to perform a calculation process and an estimation process. The calculation process includes a process of calculating, in accordance with the voltage value, an evaluation value for evaluating a degree of polarization mitigation after charging or discharging of the battery. The estimation process includes a process of estimating the presence or absence of the deterioration in accordance with the evaluation value.

摘要： Described herein are methods and systems for restoring LiMLE cells by cycling such cells using restoring conditions comprising specially selected restoring discharge current (e.g., at least 1 D) and a restoring charge current (e.g., less than 0.5 C). This restoration cycling can be triggered when a LiMLE cell reaches a restoring threshold, determined based on one or more of the following operating and resting conditions: a discharge capacity, an overpotential, an impedance, a direct-current (DC) resistance, the rest period duration, an open circuit voltage, operating discharge and/or charge currents, and an operating cycle count. The restoring threshold is selected to reflect the negative electrode state in a LiMLE cell. The restoring conditions are selected to change this negative electrode state to improve the performance of the LiMLE cell. For example, the restoring discharge can reduce the cell's state of charge (SOC) by at least 10%.
