  • Patent number: 11063327
    Abstract: A secondary battery is provided with a power generation element, an electroconductive member, an external short circuit, a current detector and an external discharge safety circuit. The power generation element has a unit cell layer that includes a positive electrode, a separator and a negative electrode stacked in that order. The electroconductive member is disposed on one outward side of the power generation element with an insulation member interposed therebetween. A lead wire connects the electroconductive member with the negative electrode tab. The current detector detects whether or not current is flowing to the lead wire. The external discharge safety circuit is provided to short-circuits a path between the positive electrode tab and the negative electrode tab outside the power generation element while current detector detects a current.

  • Patent number: 11056892
    Abstract: Aspects of the present disclosure are directed to a method and/or apparatus for use with battery cells having an actual voltage-sourcing level that is at or above a specified battery-output level. Switch circuitry is selectively activated for passing current, and a monitoring circuit is responsive to activation of the switching circuitry by distributing energy corresponding to an actual voltage-sourcing level of a particular one of the battery cells to a voltage node. A voltage-measurement circuit provides an indication of the actual voltage-sourcing level across the particular battery cell by ascertaining voltage differentials between the voltage node and respective voltage nodes of the battery cell, the ascertained voltage differentials being less than the specified battery-output level.

  • Patent number: 10991995
    Abstract: A method for operating a battery of an at least partially electrically operated/driven functional device, a corresponding battery, and a corresponding functional device. A control unit of the battery receives measurement signals relating to a respective parameter of the battery cells from a plurality of switchable battery cells of the battery. The control unit prepares a location-resolved distribution function of the respective cell parameter within the battery on the basis of the measurement signals. By activating the switching elements of the switchable battery cells according to a predetermined switching rule, the control unit produces a pattern of battery cells switched to active and passive. A predetermined location-resolved distribution function of the respective cell parameter is fulfilled and at least one predetermined secondary condition relating to an operation of the functional device and/or the battery is maintained.

  • Patent number: 10983172
    Abstract: Described herein are systems and methods that allow for automatic detection of the highest available cell voltage and/or location of the top voltage in a battery stack, in real-time, without having to use separate, dedicated PCBs for different battery stack configurations, and without having to manually configure PCBs based on the number of cells each battery stack has. In certain embodiments, automatic detection is accomplished by a software-configurable battery management circuit that supports any battery pack size without the need to perform hardware modifications or the added cost of customizing boards for battery stacks that have different numbers of cells. In addition, a novel diode-OR analog multiplexer circuit allows the chip to be powered prior to the selection of the top cell.

  • Patent number: 10978887
    Abstract: A fast charging battery system and method for charging battery systems can be applied to most battery types in use for electric vehicles (EVs), electronic devices, and wireless electrical machines. The system could employ industry proven battery charger systems and off-the-shelf electrical components (e.g., contactors, relay switches, semiconductor parts, DC-DC converters, and the like) to keep cost and complexity low. The system provides for two or more charging ports in the electronic device, such as an EV, that may be able to receive and recognize a charging type, such as charging voltage, current and the like, and provide directed charging to multiple battery sub-packs that make up the entire battery. By charging sub-packs in parallel, the charge time can be substantially reduced.

  • Patent number: 10965211
    Abstract: A technology for suppressing a performance degradation of a solar battery caused by PID is provided. A conversion device includes a DC/DC converter and a control part. A solar battery is connected to an input end of the DC/DC converter. When direct-current power generated by the solar battery is converted and output, the DC/DC converter makes a potential of a negative electrode of the solar battery to be higher than a potential in a negative electrode of the output when the power input from the solar battery exceeds a prescribed value. The control part changes a voltage of the power output from the solar battery to detect a peak value of the power, and stops the operation of the DC/DC converter when the peak value is smaller than the prescribed value.
