  • Patent number: 11145914
    Abstract: A battery system for storing electric energy, e.g. from a wind turbine. Battery modules are distributed in a housing and cooled by a housing cooling system. A monitoring algorithm receives input data from temperature and current sensors in battery cells from each of the battery modules, a state of a cooling system in each of the battery modules, a state of the housing cooling system such as fan rotation speed, and auxiliary inputs such as an ambient temperature. The monitoring algorithm processes the input data according to a predetermined model based on knowledge about the battery system. The model based estimated temperature within a specific battery cell is compared with the measured temperature to determine whether an abnormal operation exists.

  • Patent number: 11124087
    Abstract: The invention relates to a method for selecting candidate energy storage cells for balancing of an electrical energy storage pack (1) comprising a plurality of energy storage cells (3). The method comprises calculating (S212) a probability that a balancing action on the selected group of cells results in that at least one of the future state of charge is lower than a lower threshold present state of charge or higher than a higher threshold present state of charge, the probability being indicative of superfluous leakage or overcharging. The probability is based on the future state of charge for each of the cells and on the statistical inaccuracy. If the probability is indicative of that superfluous leakage or overcharging is unlikely to occur, selecting (S214, S214?) the group of cells as candidates for a balancing action. The invention further relates to a corresponding system and to a vehicle.

  • Patent number: 11114705
    Abstract: A circuit that indicates a warning of low battery life so that an instrument supported by a battery, may have the battery replaced before the battery dies. A switch and series resistor may be connected between the battery and a capacitor. The switch may turn on when the voltage on the capacitor is below a first predetermined voltage limit, and the switch may be turned off when the voltage at the capacitor is above a second predetermined voltage limit. When the switch is on, a voltage on the resistor can be measured and current consumption can be calculated with measured voltage, resistor value and duty cycle of the switch. When the battery is discharged, its internal resistance and then its duty cycle may increase. When the duty cycle hits 100 percent, the battery may be nearly dead but with enough life for the circuit to issue the low battery warning.

  • Patent number: 11097633
    Abstract: Techniques are described for implementing automated control systems to control operations of target physical systems including batteries, such as based at least in part on models of the batteries' dynamic behaviors that are generated by gathering and analyzing information about the batteries' operations under varying conditions. The techniques may include, for each of multiple charge levels of a battery and for each of multiple resistive loads, injecting multi-frequency microvolt pulses into the battery, and using sensors to collect time changes of the responses to these pulses. Information about the inputs and the responses is then analyzed and used to generate an incremental parametric state model representing the internal dynamics of the battery, which is further used to control additional ongoing battery operations (e.g., to control whether and how much power is supplied to and/or extracted from the battery in a current or future time period).
