摘要： A method of hybrid power management is provided in the present invention, comprising steps of: providing a hybrid power output device being coupled to a load and comprising a fuel cell module and a secondary cell module; determining a plurality of threshold values, each representing one of output power modes of the hybrid power output device respectively; and monitoring a characteristic value output from the fuel cell module and comparing the characteristic value with the threshold values to determine one of the output power modes to supply power to the load. Moreover, the present invention further provides a system of hybrid power management using the foregoing method to control switches to select from the output power modes such as supplying power from the fuel cell module only, from both the fuel cell module and the secondary battery, or cutting off power supply to the load according to the power state of the fuel cell module.
摘要翻译： 本发明提供了一种混合动力管理方法，包括以下步骤：提供耦合到负载并包括燃料电池模块和二次电池模块的混合动力输出装置; 确定多个阈值，每个阈值分别代表混合动力输出装置的输出功率模式之一; 以及监视从所述燃料电池模块输出的特性值，并将所述特征值与所述阈值进行比较，以确定向所述负载供电的输出功率模式之一。 此外，本发明还提供一种使用上述方法的混合动力管理系统，用于控制开关以从输出功率模式进行选择，例如仅从燃料电池模块和二次电池供应来自燃料电池模块的功率，或 根据燃料电池模块的电源状态切断负载的电源。

摘要： A vacuum storage apparatus includes a bag and a pump. A zipper is operable to close a mouth of the bag. The pump includes a shell, a bottom plate and two check valves. The shell includes a flange extending from an air bag. The air bag includes a chamber. The flange includes a vent in communication with the chamber and is inserted in and connected to the bag so that the air bag extends out of an aperture of the bag. The bottom plate includes an entrance and is connected to the flange so that the entrance is in communication with the chamber. The first check valve is located between the flange and the bottom plate so that an inlet thereof is in communication with the chamber and an outlet thereof is in communication with the vent. The second check valve is connected to the bottom plate, over the entrance.
