Abstract: 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.

Abstract: 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.

Abstract: The method of location-based charging for electric vehicles provides for secure charging of electric vehicles by applying various charging mechanisms depending on users' and suppliers' specific attributes. When an operator of an electric vehicle connects the electric vehicle to electric vehicle supply equipment, a message is securely received by the electric vehicle supply equipment, which includes a set of operator-specific parameters. Based on the set of operator-specific parameters, a secure notification is transmitted to an owner of the electric vehicle supply equipment requesting authorization for the operator to charge the electric vehicle. The applicable charging mechanism of the electric vehicle is applied based on the owner's authorization message transmitted to the electric vehicle supply equipment and the set of operator-specific parameters.
