  • Patent number: 12013440
    Abstract: The present disclosure is directed to providing an SOC estimating apparatus and method, which may accurately estimate OCV and SOC of a battery cell even when a voltage rough graph of the battery cell exhibits a nonlinear rough graph. According to an aspect of the present disclosure, the SOC estimating apparatus has an advantage of estimating the SOC of the battery cell more accurately and more reliably. In addition, the SOC estimating apparatus has an advantage of estimating the final SOC of the battery cell quickly even in an environment where it is difficult to secure a sufficient rest period, by estimating the second SOC based on voltage information obtained during the charging and discharging interruption time.

  • Patent number: 11894708
    Abstract: Methods and apparatuses are disclosed for adjusting a maximum charge amount of a battery. Batteries have preferred usage parameters, such as charging rates, maximum charge amounts, heat, etc. Throughout a battery's lifespan, it is used in different ways that are outside of these parameters. This slowly degrades the quality of the battery. According to the present disclosure, this usage is monitored and accounted for so as to increase the lifespan of the battery and prevent or reduce further degradation. Specifically, the usage is separated into bins, such as temperature and voltage bins. Each bin is associated with a different weighting factors. The amount of time the battery has spent in each bin is multiplied by the corresponding weighting factors, and these values are summed to provide an overall degradation value of the battery. Charging or other aspects of the battery are then controlled according to this degradation value.

Accordingly, even if the temperature of the battery is outside the charge allowance range due to the discharge of the battery built in the cleaner, the battery can be charged more quickly, thereby reducing the total time required for charging the battery.

  • Patent number: 11846679
    Abstract: Rechargeable battery monitoring and control is provided using a non-linear rate-of-change failure threshold. A non-linear rate-of-change failure threshold is obtained indicative of an operational state abnormality in a rechargeable battery cell, and during the operational state of the rechargeable battery cell, a control compares an actual voltage rate-of-change of the rechargeable battery cell to the non-linear rate-of-change failure threshold. Based on the actual voltage rate-of-change of the rechargeable battery cell exceeding the non-linear rate-of-change failure threshold, the control identifies the operational state abnormality in the rechargeable battery cell. Based on identifying the operational state abnormality in the rechargeable battery cell, the control discontinues the operational state of the rechargeable battery cell.

  • Patent number: 11840158
    Abstract: A method includes determining a threshold capacity associated with at least a first unmanned aerial vehicle (UAV) and a second UAV. The method includes initially setting a target charge voltage of a first battery of the first UAV to less than a full charge voltage to limit a state of charge of the first battery based on the threshold capacity. The method includes, over a lifetime of the first battery of the first UAV, periodically comparing a full charge capacity of the first battery to the threshold capacity. The method includes, based on the comparing, periodically adjusting the target charge voltage of the first battery, such that, as the full charge capacity of the first battery decreases with age, the target charge voltage increases towards the full charge voltage of the first battery.

    Abstract: A battery management system includes a control device and a storage. The storage stores at least one trained neural network. The trained neural network includes an input layer that accepts input data that represents a numeric value for each pixel in an image where a prescribed CCV waveform (a CCV charging waveform or a CCV discharging waveform) of a secondary battery is drawn in a region constituted of a predetermined number of pixels, and when input data is input to the input layer, the trained neural network outputs a full charge capacity of the secondary battery. The control device estimates the full charge capacity of a target battery by inputting input data obtained for the target battery into the input layer of the trained neural network.

  • Patent number: 11830990
    Abstract: A battery system includes a rechargeable energy storage system (RESS) having battery cells, and a battery controller network configured to execute two-level logic to detect a thermal runaway condition. The network includes RESS-embedded cell monitoring units (CMUs) electrically connected to a respective cell group, and measuring and wirelessly transmitting cell data. A battery control module (BCM) is in communication with the CMUs. Thermal runaway sensors are mounted on the CMUs and/or the BCM. A master controller connected to the BCM includes a thermal runaway detection algorithm configured to detect a thermal runaway condition occurring within the RESS. The BCM uses data from the CMUs and thermal runaway sensors to execute first logic level which determines when to wake up the master controller. The master controller, in response to receipt of a wakeup signal, executes a second logic level to execute the algorithm.
