摘要： A fully integrated circuit configuration that can be utilized to prevent abnormal discharge or overcharge in ultra-portable electronic systems is described. This battery protection integrated circuit can be enhanced by the addition of traditional battery protection schemes such as current limiting, overcurrent clamping, under voltage lock out and over voltage protection. This battery protection scheme utilizes a high side switch approach utilizing an ultra-low leakage PMOS power switch rather than the traditional low side NMOS switching.

摘要： This application is directed to an electronic device (100) powered by one or more rechargeable battery cells (120). The electronic device (100) includes a first negative temperature coefficient (NTC) thermistor (208) proximate to the battery cells (120), and an open capacitor (210) coupled in parallel with the NTC thermistor (208). The open capacitor (210) has an open area (214) and two electrodes (212a, 212b) that are at least partially exposed via the open area (214) and electrically isolated. The electronic device (100) further includes a control circuit coupled to the NTC thermistor (208) and the open capacitor (210). The control circuit is configured to detect a voltage drop across the NTC thermistor (208) and the open capacitor (210) if conductive liquid enters the open area (214) of the capacitor (210) and electrically connects the two electrodes (212a, 212b) that are at least partially exposed via the open area (214).

摘要： In one aspect, a method to determine a capacity of a microgrid includes applying a current test load to the microgrid and measuring a current through an energy storage device, the current indicating a charging status of the energy storage device based on a current load being applied to the microgrid through activated power outlets being served by the microgrid and the current test load, the energy storage device being integrated with the microgrid. The method also includes, responsive to a determination that the measured current based on the current load being applied to the microgrid and the current test load indicates that the energy storage device is discharging, determining the capacity of the microgrid, wherein the capacity is the current load being applied to the microgrid through activated power outlets and a test load applied to the microgrid immediately preceding the current test load.

摘要： An energy storage device management system can include a management portion for charging/discharging an energy storage device and an ultrasound interrogation portion for passing ultrasound energy through the energy storage device during charge/discharge cycles. A memory stores a stream of capture data instances derived from ultrasound energy exiting the energy storage device and baseline ultrasound data instances corresponding with the energy storage device during normal charging/discharging thereof. A processor can compare each capture data instance with the baseline ultrasound data and detect abnormal operating states of the energy storage device. A warning system can issue a notification when abnormal operating states are detected.
