    Abstract: A battery system may include multiple battery cells grouped into modules. Each battery module may have a diffuser plate to direct the hot gases and molten material that are ejected during cell failure. The gas and material may be directed away from the nearest neighboring cells in the event of a single cell thermal runaway. Residual thermal energy is wicked away, absorbed or contained to keep heat away from the neighboring cells. These and other features may manage the blast energy and residual thermal energy of a single cell failure event.

  • Patent number: 10845419
    Abstract: An assembled battery is formed from multiple standard cells each having a standard capacitance and a single twofold cell having a capacitance twofold larger than the standard capacitance. When detecting the SOC of a reference standard cell, a system control circuit acquires from a memory a potential difference-SOC characteristic curve indicating the relationship between the potential difference between the reference standard cell and the twofold cell and the SOC of the reference standard cell. Moreover, the system control circuit detects the potential difference between the reference standard cell and the twofold cell, and then compares the detected potential difference with the potential difference-SOC characteristic curve to detect the SOC value of the reference standard cell.
