摘要： An electronic device (100) includes a battery (110), a battery gauge (120), and a processor (130). The battery (110) is configured to supply power to the electronic device (100). The battery gauge (120) is configured to gauge the battery (110) to generate a plurality of remaining capacities (R1-RN), a battery temperature (TB), and a battery voltage (VB) of the battery (110). The processor (130) is configured to sequentially read the plurality of remaining capacities (R1-RN). The processor (130) determines whether a preset condition is met according to the battery temperature (TB) and the battery voltage (VB) in a case that a read remaining capacity is equal to a cut-off capacity and a read previous remaining capacity is greater than a preset capacity. The processor (130) performs a capacity correction process in a case of determining that the preset condition is met. The capacity correction process includes using the read previous remaining capacity as a correction capacity (NC) and reporting the correction capacity (NC) to a system circuit (140).

摘要： A battery system may include a plurality of battery packs, each of which includes a plurality of battery banks, and a battery management system that calculates a plurality of internal resistance (DCIR) values of the plurality of battery banks in each of the plurality of battery packs, and performs correction on a first internal resistance value related to a battery bank at a predetermined first position in each battery pack, and diagnoses whether the battery bank at the first position is abnormal, on the basis of the corrected first internal resistance value. Each of the plurality of battery banks may include a plurality of battery cells connected in parallel, and the first position is the same position in each of the plurality of battery packs.

摘要： The dependency of the open circuit voltage on the state of charge of a battery, i.e., the OCV curve (613) is determined, e.g., to facilitate determination of the state of health or state of charge of the battery. The OCV curve (613) is determined based on the values of multiple independent parameters (611, 612), e.g., half-cell potentials derived from degradation modes such as loss of lithium inventory or loss of active material at the cathode or anode.
