摘要： Described are techniques for turning on a power supply unit. The techniques include a processor unit in the power supply unit to monitor an output voltage bus, wherein the power supply unit is connected to the output voltage bus. The processor unit in the power supply unit switches on the power from the power supply unit to the output voltage bus in response to a bus voltage on the output voltage bus not being greater than a voltage threshold for a safe time period. The processor unit switches on the power from the power supply unit to the output voltage bus in response to the bus voltage being greater than voltage threshold for a time stable period.

摘要： A starter battery with a total battery voltage exceeding a supply voltage requirement of an electrical system. An alternator provides a charging voltage that corresponds with the supply voltage requirement of the electrical system. A total battery voltage equal to the sum of cell voltages exceeds the supply voltage requirement of the electrical system. A step-down voltage regulator reduces the total battery voltage to correspond with the supply voltage requirement and a boost voltage regulator increases the charging voltage from the alternator when charging the starter battery to the total battery voltage. When detecting a degraded cell, the step-down voltage regulator continues to regulate the total battery voltage to correspond with the supply voltage requirement after the cell has degraded and the boost voltage regulator is bypassed when charging the starter battery to no longer increase the charging voltage from the alternator when charging the starter battery.

摘要： A wet-cell in a battery is configured with a set of i-electrodes. A collection surface inside the wet-cell is identified where electrically conductive debris accumulates to an expected height. A first i-electrode of a first polarity in the set of i-electrodes is configured to be located at substantially the expected height inside the wet-cell. A second i-electrode of a second polarity in the set of i-electrodes is configured to be located at substantially the expected height inside the wet-cell. A first indication device is installed where the first i-electrode and the second i-electrode are configured in an electrical circuit via the first indication device, wherein when the electrically conductive debris has accumulated up to the expected height, makes simultaneous electrical contact with the first i-electrode and the second i-electrode and activates the first indication device.

摘要： A wet cell battery, where a first cell in a wet-cell battery includes a set of anode electrodes and a set of cathode electrodes, and where electrically conductive debris accumulates on a surface inside the first cell to an expected height. An anode electrode in the set of anode electrodes has an anode end closest to the surface, and a cathode electrode in the set of cathode electrodes has a cathode end closest to the surface. A first gap distance between the anode end and the surface is different from a second gap distance between the cathode end and the surface. When the electrically conductive debris accumulates up to the expected height, the debris fails to make simultaneous electrical contact with the anode electrode and the cathode electrode due to the different gap distances.

摘要： A method for managing a battery to perform a final action, the method includes determining a battery supplying power to an electronic device is discharging and receiving battery specification information for the battery. The method includes receiving environmental condition information for the battery and determining an open circuit voltage for the battery. The method includes determining a base capacity for the battery, a first capacity reduction for the battery based on the battery specification, and a second capacity reduction for the battery based on the environmental condition information. The method includes determining an overall expected capacity for the battery based on the first capacity reduction and the second capacity reduction, where the overall expected capacity represents available energy. Responsive to determining the available energy for the battery is less than a required energy to perform an action prior to battery depletion, the method includes sending a warning notification.
