The battery monitoring unit and the resistance measuring device monitoring a change in surface temperature on the casing of the battery during a charging or discharging of the battery, compare the change in surface temperature with an expected change in surface temperature during the charging or discharging of the battery, and determine that a swelling of the battery has occurred when the change in surface temperature is less than the expected change in the surface temperature.

Abstract: An amount of power that is provided to a load is measured. The load is coupled to a battery backup unit (BBU) or an uninterruptable power supply (UPS). The amount of power is stored into a history of power draw for the load. The history of power draw is used to determine a time period or a situation when additional power is required by the load or reduced energy can be provided to the load. The charge of the BBU or the UPS is increased or reduced prior to the time period or the situation when the additional power is required by the load or the reduced energy can be provided to the load.

Abstract: A method and apparatus permit the testing of electrochemical cells. The apparatus includes a heat source, a chamber, and a diffuser coupling the heat source to the chamber. The heat source applies heat via the diffuser to a pin-point section of the electrochemical cell. This application of heat causes a thermal runaway condition due to a localized internal short circuit in the electrochemical cell. It is then determined whether the electrochemical cell has vented, ruptured, or exploded in response to the application of the heat source to the thermal runaway pin-point section of the electrochemical cell.
