摘要： A method to control storage into and depletion from multiple energy storage devices. The method enables an operative connection between the energy storage devices and respective power converters. The energy storage devices are connectible across respective first terminals of the power converters. At the second terminals of the power converter, a common reference is set which may be a current reference or a voltage reference. An energy storage fraction is determined respectively for the energy storage devices. A voltage conversion ratio is maintained individually based on the energy storage fraction. The energy storage devices are stored individually with multiple variable rates of energy storage through the first terminals. The energy storage is complete for the energy storage devices substantially at a common end time responsive to the common reference.

摘要： An energy conversion system, an energy conversion method, and a power system. The energy conversion system may include a bridge arm conversion module, a direct current (DC)/DC conversion module, a motor, a bus capacitor, and a control module. The control module may be configured to control a bridge arm switch action in the bridge arm conversion module, drive the motor based on an alternating current input voltage supplied by a power supply, form a bus voltage at two ends of the bus capacitor, and control the DC/DC conversion module to charge a traction battery and an auxiliary battery based on the bus voltage. The traction battery and the auxiliary battery can be charged while the motor is driven, thereby achieving higher energy conversion efficiency, low costs, and strong applicability.

摘要： A rigid wireless charging mouse pad includes a rigid board layer, a double-sided adhesive plate and a coil. The underside of the rigid board layer has a single-ring groove with an inner top groove wall. The double-sided adhesive plate is adhered to the inner top groove wall. The coil has surrounding rings arranged side by side with one another to form a coil module which is stacked on the double-sided adhesive plate in the single-ring groove and adhered by the double-sided adhesive plate to achieve a wireless charging effect by the mouse pad in the condition of having only one single-ring groove on the rigid board layer, so as to achieve the effects of reducing manufacturing difficulty, lowering manufacturing cost, and improving market competitiveness.
