A method and apparatus for adjusting the charge for a battery under a power sharing arrangement is disclosed. In one embodiment, the method comprises determining if power output capacity of an alternating current (AC) adapter is less than or greater than a system power requirement for a system that receives power from the AC adapter and a battery, determining a charge current for charging the battery from the AC adapter, based on a voltage range of the battery, the current charge being less than excess current available from the AC adapter in view of determining that the power output capacity of the AC adapter is greater than the system power requirement, and controlling a battery charger to charge the battery with the charge current by specifying the charge current to the battery charger if the power output capacity of the AC adapter is greater than the system power requirement.

Adaptive charge current for a battery

Provided is a memory device, comprising a non-volatile memory, an energy store coupled to an input power module of the non-volatile memory, and a power management module configurable to determine whether or not to supply backup power to the non-volatile memory via the energy store to initiate a shutdown process, based on differentiating a voltage glitch from an actual loss of power in a power line. Provided also is a computational device that includes the memory device. Provided also is a method in which a power management module of the memory device determines whether or not to supply backup power to the non-volatile memory via the energy store to initiate a shutdown process, based on differentiating a voltage glitch from an actual loss of power in a power line.

Management of power loss in a memory device

Examples include techniques to power down output power rails for a storage device. In some examples, energy discharged from output capacitors for output power rails and energy discharged from input capacitors may be used to facilitate power down of power rails for the storage device.

Techniques to power down output power rails for a storage device

Power management circuitry initiates storage of backup energy in an energy storage resource. The backup energy is stored to power an electronic circuitry during a power failure condition in which primary power is unavailable to power the electronic circuit. During a test mode, the power management circuitry selectively discharges the backup energy stored in the energy storage resource at multiple different energy discharge rates to test the energy storage resource.

Hold-up energy storage and management

These present disclosure provides techniques to determine the capacitance of a power loss capacitor based on voltage ripple. The power loss capacitor may be a power loss capacitor for a power loss shutdown system of a solid state drive. The capacitance may be determined as a function of the voltage ripple and a period of the voltage ripple during a natural discharge and a controlled discharge of the power loss capacitor.

A battery cell structure may include a battery cell, a first pouch layer to substantially surround the battery cell, a second pouch layer to substantially surround the first pouch layer, and a shielding layer in the battery cell structure.
