Patent number: 9466985Abstract: A power controlling method for a power supplying system coupled to a load is disclosed. City energy is detected. It is determined whether the city energy corresponds to a first pre-determined condition. When the city energy corresponds to the first pre-determined condition, the city energy is transformed to generate a main power to the load. When the city energy does not correspond to the first pre-determined condition, a fuel cell unit is activated to provide a backup power to the load.Type: GrantFiled: May 7, 2013Date of Patent: October 11, 2016Assignee: Chung-Hsin Electric & Machinery Mfg. Corp.Inventors: Yi-Fan Wu, Ruiming Zhang, Shuhai Quan, Rui Quan

Patent number: 9197099Abstract: A power supply system driving a load including a main power apparatus and a backup power apparatus is disclosed. The main power apparatus provides main power to the load according to city power. The backup power apparatus provides backup power to the load when the city power does not correspond to a first pre-determined condition and includes a recombination unit, a fuel cell unit, a transformation unit, and a control unit. The recombination unit recombines a methanol component to a hydrogen component. The fuel cell unit receives the hydrogen component to generate a first power. The transformation unit detects the city power and transforms the first power to generate the backup power. When the city power does not correspond to a first pre-determined condition, the control unit activates the reformer, the fuel cell unit, and the transformation unit to generate the backup power.Type: GrantFiled: May 6, 2013Date of Patent: November 24, 2015Assignee: Chung-Hsin Electric & Machinery Mfg. Corp.Inventors: Yi-Fan Wu, Ruiming Zhang, Chin-Hsien Cheng, Shuhai Quan, Rui Quan

Patent number: 8952666Abstract: An energy adjustor coupled between a fuel cell group and a secondary battery group is disclosed. A load is coupled to the secondary battery group in parallel. The energy adjustor includes a boost regulation module, a drop regulation module, a detecting module and a control module. The boost regulation module boosts an output voltage of the fuel cell group to generate a first adjustment voltage according to a first control signal. The drop regulation module drops the first adjustment voltage to generate a second adjustment voltage to the load according to a second control signal. The detecting module detects at least one of the fuel cell group, the boost regulation module, the drop regulation module and the load to generate a detection result. The control module generates the first and the second control signals according to the detection result.Type: GrantFiled: February 22, 2012Date of Patent: February 10, 2015Assignees: Chung-Hsin Electric & Machinery Mfg. Corp., Wuhan Haixinneng Electric Limited CompanyInventors: Shuhai Quan, Liang Huang, Ruiming Zhang, Rui Quan, Jin Quan, Ying Xiong, Qihong Chen, Changjun Xie, Cheng Zeng, Bo Chen

Publication number: 20130084513Abstract: An energy adjusting method for controlling output energy of a fuel cell group, wherein at least one of the fuel cell group and a secondary battery group drives a load is disclosed. The voltage of the fuel cell group is boosted by a boost regulation module to generate a first adjustment voltage. The boost regulation module boosts the voltage of the fuel cell group according to a first control signal. The first adjustment voltage is dropped by a drop regulation module to generate a second adjustment voltage to the load. The drop regulation module drops the first adjustment voltage according to a second control signal. At least one of the fuel cell group, the boost regulation module, the drop regulation module and the load is detected to generate a detection result. The first and the second control signals are generated according to the detection result.Type: ApplicationFiled: February 22, 2012Publication date: April 4, 2013Applicants: WUHAN HAIXINNENG ELECTRIC LIMITED COMPANY, CHUNG-HSIN ELECTRIC & MACHINERY MFG.
