Abstract: A microcontroller, processor, and/or software (SW) monitors a battery degradation indicator such as battery State-Of-Health (SOH), impedance or other attributes, and calculates battery degradation rate and regulates burst power, battery charging speed and/or battery charging limit to meet users' expectation of battery service life. The microcontroller, processor, and/or SW increases the burst power, battery charging speed and/or battery charging limit when 1/SOH or impedance change rate (or related parameter) is smaller than expected and there is more longevity budget than expected. In another example, the microcontroller, processor, and/or SW decreases the burst power, battery charging speed and/or battery charging limit when 1/SOH or impedance change rate (or related parameter) is greater than expected and there is less longevity budget than expected.

Abstract: Techniques are provided for operating a computing system in a peak power mode while avoiding increased degradation of a battery. The peak power mode include cycles with peak and off-peak currents. The amplitude and duration of the peak and off-peak currents are governed by a thermal/heat budget of the battery. A processor can read the battery information during usage and calculate one or more parameters which are derived from heat. If a parameter is smaller than a reference value, the processor can update the peak power parameters to provide an increase in peak current/power and/or duration. If a parameter is larger than the reference value, no heat budget is available to provide an increase in peak current/power and/or duration. The thermal/heat budget can be enforced over each cycle of the peak power mode or in a summation over multiple cycles.

Abstract: An input device includes: an operating component that includes an operating surface and is operated by an operating body; a rotation detector that detects rotation of the operating component; a touch sensor that detects a contact position of the operating body on the operating surface; and a controller that outputs a detection result of the rotation detector when the rotation detector detects the rotation of the operating component, and outputs a detection result of the touch sensor when the touch sensor detects the contact position of the operating body. When the rotation detector detects the rotation of the operating component and the touch sensor detects the contact position of the operating body, the controller outputs the detection result of the rotation detector and does not output the detection result of the touch sensor for a first time period starting from the detection by the rotation detector.

Abstract: A scheme to initiate fast charging of a battery based on inference, situation, and/or need. The scheme uses a situational fast charging algorithm that detects user's situation and judges if fast battery charging is needed and enables fast charging. Once the need for fast charging need is detected, there are at least two options to follow. In the first option, when a charger cannot provide enough power to support both system and battery fast charging, the system turns down system power (e.g., reduces display brightness) and starts fast charging with available charger power to a sufficient charge level. In the second option, when a charger can provide enough power to support both system and battery fast charging, the system starts fast charging to a sufficient charge level.

Abstract: Estimating a charge state for a flat-voltage profile battery can be accomplished using impedance measurements. For example, an impedance measurement can be used to form a fuel gauge for a lithium-air (Li-Air) battery. As the impedance of a Li-Air battery increases during discharge, it corresponds to a state of charge (i.e., a charge state). The impedance can be used to create charge state data to use with a fuel gauge.

Abstract: In some examples, a control unit is configured to adjust charge termination voltage of a rechargeable energy storage device. The control unit is adapted to charge the rechargeable energy storage device to a charge termination voltage where the rechargeable energy storage device has capacity to support peak load but comes close to a system shutdown voltage after supporting peak load. The control unit is also adapted to increase the charge termination voltage if a voltage of the rechargeable energy storage device is near a system shutdown voltage after supporting peak load.

Abstract: Techniques for battery retention are disclosed. In the illustrative embodiment, a thin polyurethane strap is used to hold a battery in place. The strap only requires a small amount of volume, allowing for a higher volume (and higher capacity) for the battery. In order to accommodate swelling, a computing device that has a battery held in place with such a strap can have an open area above the battery. The strap may have ridges to contact the battery and the component above the battery beyond the open area. If the battery swells, the ridges may be pressed down, accommodating the swelling battery.

Abstract: A workload dependent load-sharing mechanism in a multi-battery system. The mechanism is an energy management system that operates in three modes—energy saving mode, balancer mode, and turbo mode. The energy saving mode is a normal mode where the multiple batteries provide power to their own set of loads with least resistive dissipation. In balancing mode, the batteries are connected through switches operating in active mode so that the current shared is inversely proportion to the corresponding battery state-of-charge. In turbo mode, both batteries are connected in parallel through switches (e.g., on-switches) to provide maximum power to a processor or load. A controller optimizes the sequence and charging rate for a hybrid battery to maximize both the charging current and charging speed of the battery, while enabling longer battery life. The hybrid battery comprises a fast charging battery and a high-energy density battery.

The control unit is adapted to charge the rechargeable energy storage device to a charge termination voltage where the rechargeable energy storage device has capacity to support peak load but comes close to a system shutdown voltage after supporting peak load. The control unit is also adapted to increase the charge termination voltage if a voltage of the rechargeable energy storage device is near a system shutdown voltage after supporting peak load.

Abstract: A battery that periodically checks an actual battery capacity or energy with charge to a preset voltage (e.g., 4.1 V). The battery then decides the battery capacity or energy. If the capacity or energy is insufficient, then an apparatus in or associated with the battery slightly increases charging voltage to a point where the capacity is sufficient (e.g. from 4.1 V to 4.11 V). The process of periodically checking and slightly increasing charging voltage is performed until charging voltage reaches specification limit (e.g., 4.2 V). The scheme described herein has benefits such as battery longevity can be extended, risk of insufficient energy reserve can be reduced, burst power can be used as long as possible, and/or even higher burst power can be used.

Abstract: Li-metal battery with a pressure chamber to allow uniform pressure on a battery. The pressure chamber is supported by metal plates (such as pressure equalization plate) used to give uniform pressure to the battery. The pressure chamber may include pressured gas, elastic material, spring plate, etc. The outer skin of the pressure chamber is free to bow, restrained at its edges by (metal) skin, but still exerts a uniform pressure on the plate that is compressing the battery cell. The pressure chamber gives uniform pressure to battery, which is used to enable high-energy density battery with, for example, 20% more battery life.
