Publication number: 20140077755Abstract: An emergency power supply starting system a lithium battery with automatic preheating function, including a lithium battery pack, an output control module, an output module, a working power supply control module, a CPU master control module, an operation panel display function module, a heater control module, a heater module, an information sampling module and a charging module is disclosed. The CPU master control module, monitoring the real-time temperature, residual capacity and user operation status of the lithium battery pack, cuts off all output functions and charges the lithium battery (power supply is resumed only after charging) if the battery voltage is too low; if the voltage is normal but battery temperature is too low, the heater control module will start the heater module to initiate the heating process driven with the low current from the lithium battery and the latter is ready for use after the lithium battery temperature returns to normal.Type: ApplicationFiled: March 15, 2013Publication date: March 20, 2014Applicants: SHANGHAI POWER STATION CO., LTD., SHANGHAI GREATWAY TOP POWER CO., LTD., SHANGHAI GUANGWEI ELECTRIC & TOOLS CO., LTD.Inventors: Zhongren Zhang, Zhenming Fan, Ke Li, Qiang Wu, Jing Shen

Patent number: 8342892Abstract: The high conductivity energy-saving clamping device comprises a clamp and a cable fixed upon the clamp. Inside the cable, the conductive material protrudes and is set on the juncture of the clamp and the external conductor. When the clamp is connected to the external conductor, the conductive material and the external conductor contact and meet. This invention possesses the following advantages: it simplifies the production technology, lessens raw materials needed for production and hence saves resources and cost by the direct contact of the conductive material and the external conductor; moreover, due to the increase of conductive contact area, it enhances the electrical conductivity by 10% to 15% compared to those common clamps which use tooth-like conductive parts to connect the external conductor. Meanwhile, the invention greatly decreases environmental pollution by omitting the plating process of tooth-like conductive parts.Type: GrantFiled: July 9, 2010Date of Patent: January 1, 2013Assignees: Shanghai Guangwei Electric & Tools Co., Ltd, Shanghai Power Station Co., Ltd, Shanghai Greatway Top Power Co., LtdInventors: YePing Fan, Yong Wu, ZhangXi Yan, Di Yu, Wei Duan

Publication number: 20100302052Abstract: The invention involves an intellectualized polarity identification device which comprises an electromagnetic module connected with a control circuit. The electromagnetic module comprises a magnetic inductor (electromagnet), a movable contact plate coaxially set with the magnetic inductor (electromagnet) and stationary contact plates. The control circuit comprises a reversed-polarity alarm protecting circuit connected with a correct-polarity conducting circuit. The reversed-polarity alarm protecting circuit comprises an alarm circuit and a protection circuit, the protection circuit comprising a diode and a photocoupler. The correct-polarity conducting circuit comprises a conduction circuit and an indicator circuit, respectively connected with the photocoupler. The intellectualized polarity identification device is electromagnetically controlled such that a closed circuit is created only when the device is connected with the correct polarity.Type: ApplicationFiled: February 9, 2010Publication date: December 2, 2010Applicant: SHANGHAI GUANGWEI ELECTRIC & TOOLS CO., LTD.Inventors: YePing Fan, ZhiLiang Jiang, WeiLing Ma, ZhongRen Zhang
