摘要： A charging circuitry (10A) includes a power electronic converter (13), a current sensor (14), a voltage boost/buck controller (15) and a charging mode controller (16). The power electronic converter (13) is configured to charge or discharge a supercapacitor (12) according to a control command (CTRL). The current sensor (14) is coupled to the supercapacitor (12) for detecting a first sensed voltage (ISENSE+) and a second sensed voltage (ISENSE-). The voltage boost/buck controller (15) is configured to generate the control command (CTRL) and a current command (IMON_OUT) according to the first (ISENSE+) and second sensed voltages (ISENSE-) and an overall feedback (FB_OUT). The charging mode controller (16) is configured to generate a current feedback (FB1) and a voltage feedback (FB2) to the voltage boost/buck controller (15) according to a driving voltage (CV), the current command (IMON_OUT) and a third sensed voltage (VSENSE) of the supercapacitor (12). The third sensed voltage (VSENSE), the current feedback (FB1) and the voltage feedback (FB2) are superposed as the overall feedback (FB_OUT) and then inputted to the same input terminal of the voltage boost/buck controller (15).

摘要： Disclosed are methods for charging batteries utilizing a charge balance approach, and charger systems using those methods. In one example, a method for charging a battery includes monitoring an amount of charge released by the battery while in a discharge state, recording the amount of charge released while in the discharge state, applying a voltage which results in current in reverse direction to the battery at a first voltage level for a time sufficient to introduce an amount of charge substantially equal to the recorded amount of charge released by the battery while in the discharge state, and maintaining the battery in a stand-by mode by applying a voltage which results in current in reverse direction to the battery at a second voltage level, the second voltage level being in a range sufficient to prevent self-discharge of the battery and insufficient to induce evaporation of electrolyte in the battery.

摘要： An electronic system which includes a power delivery surface that delivers electrical power to an electrical or electronic device. The power delivery surface may be powered by any electrical power source, including, but not limited to : wall electrical outlet, solar power system, battery, vehicle cigarette lighter system, direct connection to electrical generator device, and any other electrical power source. The power delivery surface delivers power to the electronic device wireelessly. The power delivery surface may deliver power via a plurality of contacts on the electrical device conducting electricity from the power delivery surface. The electrical device may be mobile device. Each contact may be shaped to improve power delivery reliability. The power delivery surface may further include circuitry to protect against accidental electrocutions.

摘要： There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a portable fuel cell power and management system (for example, hydrogen and/or methanol based systems), components and/or elements thereof, as well as techniques for controlling and/or operating such systems. The fuel cell power management system (and method of controlling and/or operating same) actively monitors, manages and/or controls one or more operating parameter(s) of the fuel cell system. For example, the system monitors, manages and/or controls the consumption and/or the rate of consumption of fuel by the system, and in response thereto, may provide and/or alert the user to amount of fuel remaining, consumed, the rate of consumption and/or the time (or estimation thereof) remaining until all of the fuel is spent. In this way, user may schedule or plan accordingly.

摘要： A parallel monitor circuit (1A) for monitoring one (C1) of serially connected plural capacitors (Cn) receiving a direct recharging current is disclosed. The circuit comprises a bypassing transistor (Q1) for bypassing the capacitor (C1) with the recharging current when the capacitor voltage (VSo1) exceeds a monitor voltage (Vr1) determined by a voltage setting circuit in order to equally recharge the capacitors. A transferring unit transfers a voltage control circuit (VS1) and an internal circuit connected to the voltage control circuit to a standby mode when the voltage control circuit receives a specific combination of voltage codes (RC1).
