Abstract: An information handling system includes a battery, a first temperature sensor, an electric heater, and a processor. The battery provides power to one or more other components of the information handling system. The first temperature sensor measures a temperature within the information handling system. The electric heater receives a current, and provides heat to the battery based on the reception of the current. The processor determines if the battery is in an idle or charging state. In response to the battery being in the idle state or the charging state, the processor receives an ambient temperature of the information handling system from the first temperature sensor. The processor determines whether the ambient temperature is below a first threshold temperature. In response to the ambient temperature being below the first threshold temperature, the processor provides the current to the electric heater to heat the battery.

Abstract: A power backup device charging system includes components coupled to a power supply system that is configured to supply power to the components, and a power backup device that is coupled to the components and the power supply system. The power backup device identifies a minimum power requirement for the components and sets a first charging threshold based on the minimum power requirement for the components. The power backup device then sets a second charging threshold that is higher than the first charging threshold and that is lower than a full charge level for the power backup device. In response to a charge level of the power backup device reaching the first charging threshold, the power backup device is charged, and in response to the charge level of the power backup device reaching the second charging threshold, the power backup device is prevented from charging.

Abstract: A power consumption/power backup-based ride-through system includes a power supply system that is configured to supply power to the one or more components. A power backup device is coupled to the one or more components and the power supply system, and operates to monitor an amount of power provided by the power supply system to the one or more components. Based on the amount of power provided by the power supply system to the one or more components, as well as characteristics of the power backup device in some embodiments, the power backup device determines a ride-through time period for which the power backup device is capable of powering the one or more components. When the power backup device detects a loss of power to the one or more components, it powers the one or more components for the ride-through time period.

Abstract: A component throttling power backup charging system includes a chassis defining a chassis housing and a chassis air inlet to the chassis housing, at least one component located in the chassis housing and adjacent the chassis air inlet, and a power backup device located opposite the at least one component from the chassis air inlet. The power backup device determines that a charging condition has been satisfied. The power backup device then determines that a temperature of air being provided to the power backup device exceeds a threshold temperature and, in response, transmits a throttling instruction that is configured to cause throttling of the at least one component. The power backup device subsequently determines that the temperature of the air being provided to the power backup device no longer exceeds the threshold temperature and, in response, performs charging operations.

Abstract: A power converter device health check system includes a circuit that connects a power input to a power output, and that includes a first transistor directly coupled to ground and a capacitor in parallel with the first transistor. A controller device is coupled to the circuit and, during boot operations, prevents first power from being provided to the first transistor via the power input, and turns off the first transistor. While preventing the first power from being provided to the first transistor and with the first transistor turned off, the controller device provides second power to a circuit location in the circuit between the first transistor and the capacitor, and then determines whether a charge of the capacitor is below a threshold charge level. If the capacitor is below the threshold charge level, the controller device transmits a power converter warning message.
