摘要： A power storage adapter may use a high efficiency charging method when supplying electrical power to a portable information handling system when the power storage adapter is not connected to AC line power. In particular, the power storage adapter may minimize or avoid supplying electrical power when an internal battery of the portable information handling system is in a constant voltage charging regime (or at a given state of charge), in which the electrical power decreases as the state of charge increases.

摘要： A charging system and charging method for a terminal (2), and a power adapter (1) and a switch power source. The switch power source comprises a first rectification unit (101), a switch unit (102), a transformer (103), a second rectification unit (104), a sampling unit (106) and a control unit (107), wherein the control unit (107) outputs a control signal to the switch unit (102) and adjusts a voltage of a first pulse waveform according to a voltage sampling value and/or a current sampling value sampled by the sampling unit (106) to obtain a primary sampling voltage, and adjusts a duty ratio of the control signal according to the primary sampling voltage, the voltage sampling value and/or the current sampling value, so that a voltage of a third pulse waveform satisfies a charging requirement. The switch power source can make an output voltage and current waveform change along with an input voltage and current waveform, so that a good power factor can be obtained. Moreover, when the switch power source is applied to the power adapter (1), a voltage of an output pulse waveform can be directly loaded to a battery of the terminal (2), so that miniaturization and low costs of the power adapter (1) can be realized.

摘要： A circuit can include a CAN bus and multiple nodes. The multiple nodes can reboot at the same time so that a Time 0 is set at boot for each node. Each node can store an ID node and determine from its ID node one time slot of a plurality of periodic time slots starting from Time 0 in which to transmit on the CAN bus. Each node can transmit messages on the CAN bus in its determined time slot subsequent to Time 0.

摘要： Various systems and methods for enhancing the performance and utilization of a battery system are described. In one method, a configuration schedule for a battery system is determined based on communications received from an external unit and the cells of the battery system are reconfigured according to the determined configuration schedule. In another method, a sequence of one or more pulses is used for energy transfer from or to at least one cell of the battery system, wherein at least one parameter of one of the sequence and the one or more pulses, is varied in a random manner. The above-noted pulse sequence may be utilized while the battery system is not supplying power to an external load.

摘要： A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To charge, the machines employ electrical current from an external source, such as the electrical grid or an electrical service of an installation location. The charging and distribution machines may distribute portable electrical energy storage devices of particular performance characteristics and other attributes based on customer preferences and/or customer profiles. The charging and distribution machines may provide instructions to or otherwise program portable electrical energy storage devices stored within the charging and distribution machines to perform at various levels according to user preferences and user profiles.
