  • Patent number: 10727525
    Abstract: A lithium ion battery including a core-shell structured fire extinguishing particle is disclosed. When the battery is overheated to a predetermined temperature, a shell of the fire extinguishing particle coated on one surface or both surfaces of a porous separator is melted, a fire extinguishing material disposed in an inner space of the shell is released into an electrolytic solution of the battery, and as a result, it is possible to prevent the battery from being ignited or exploded even though the battery is overheated. Further, the melted shell clogs pores of the porous separator to block lithium ions from moving, such that the battery is blocked from being driven, thereby preventing the battery from being overheated any more.

  • Patent number: 10193198
    Abstract: A battery management device includes an SOC estimation unit, a storage unit, and a lithium deposition determination unit. The lithium deposition determination unit compares a differential coefficient of a battery voltage with respect to an SOC estimated by the SOC estimation unit and a differential coefficient of a battery voltage with respect to a reference SOC read from the storage unit, and determines that, if a difference is observed between the differential coefficients, lithium is deposited in a lithium ion secondary battery.

  • Patent number: 10153521
    Abstract: Systems and methods are disclosed for detecting a battery pack having an operating issue or defect. In an embodiment, a balancing charger may be configured to charge a battery pack. An amount of time that the balancing charger is operating may be recorded. The recorded time may then be compared to a threshold time that indicates a determined variance from an expected operating time. If the recorded time exceeds the threshold time, the battery pack may be determined to have an operating issue or defect. In an embodiment, the threshold time may be adjusted based on an average battery cell or battery module temperature of the battery pack. In various embodiments, an alert may also be issued in response to determining that the battery pack has an operating issue or defect and operation of the battery pack may be halted to prevent any potential adverse effects.
