| 20110081567 | BATTERY MODULE ASSEMBLY OF STARTING POWER UNIT FOR POWER GENERATOR - A battery module assembly is composed of a main body, a plurality of battery modules, and at least one fastening member. The main body includes a plurality of compartments, each of which can communicate with the outside thereof and which are vertically arranged along at least one stack. The battery modules are removably mounted to the compartments respectively. Each of the at least one fastening member is made of electrically conductive material and mounted to the battery module according to the arrangement of the compartments to enable each of the battery modules to be mechanically and electrically connected with the fastening member. Therefore, the battery module assembly enables the battery modules to be conveniently replaced and maintained. | 04-07-2011 |
| 20110080299 | EMERGENCY POWER ACTIVATION DEVICE - An emergency power activation device includes at least one power module and a main control module. Each of the at least one power module includes an output end. The main control module includes an interface unit and a monitoring unit. When the interface unit is electrically connected with the power module, the electric energy stored in the power module can be outputted to the output end. The monitoring unit monitors the power storage of the power module and the electric connection between the power module and the main control module in real time. In this way, the emergency power activation device can keep the power supply stable while on standby for a long time and monitor the storage of its internal electric energy for an emergency power generator. | 04-07-2011 |
| 20110064994 | POWER SUPPLY ASSEMBLY - A power supply assembly composed of an electric storage device and an electric energy conversion device. The electric storage device includes two electrodes. The electric energy conversion device includes at least one lithium iron phosphate battery. The at least one battery is electrically connected with the electrodes. In light of this, the power supply assembly can have denser electric storage and higher discharge rate, such that power supply assembly can discharge stably, have a longer working life, and have preferable discharging effect under the low-temperature environment. | 03-17-2011 |
| 20100294800 | PORTABLE ELECTRICAL LIQUID DISPENSING APPARATUS - A portable electrical liquid dispensing apparatus includes a housing, a power supply detachably connected with the housing, a driving unit accommodated in the housing and electrically connected with the power supply, a liquid dispensing unit accommodated in the housing and coupled to the driving unit, a first dispensing pipe having a first entry end and a first exhaust end connected with the liquid dispensing unit, and a second dispensing pipe having a second entry end connected with the liquid dispensing unit and a second exhaust end. When the electrical liquid dispensing apparatus is used, the liquid dispensing unit can be driven by the driving unit to dispense the fuel from a fuel tank into an agricultural machine through the first dispensing pipe and the second dispensing pipe, thereby enhancing the efficiency and convenience of refueling operation. | 11-25-2010 |
| 20100052602 | ELECTRICAL ENERGY STORAGE DEVICE FOR SOLAR CELL - An electrical energy storage device for a solar cell includes at least one electrode substrate coated with a oxide or mixed oxides layer. When the electrical energy storage device is electrically connected with a receive unit of the solar unit in parallel, the electrical energy storage device can have the advantages of high electric energy density, enhancing the charging efficiency of the solar cell, and reducing the charging time of the solar cell. | 03-04-2010 |
| 20090284076 | FAULT-TOLERANT BATTERY SET AND START-UP BATTERY MODULE - A fault-tolerant battery set and a start-up battery module are described. The fault-tolerant battery set includes a main battery module, a battery monitoring unit, a control switch unit, and a back-up battery module. The main battery module includes a battery unit and a battery monitoring circuit. When the battery unit fails, the control switch unit conducts a power supply connection path according to a failure signal sent from the battery monitoring circuit, so as to replace the failed main battery module with a back-up power provided by the back-up battery module through the power supply connection path. | 11-19-2009 |
| 20090038815 | POWER HAND TOOL - A power hand tool is disclosed to include a Li-battery set, an electric power storage device electrically connected in parallel to the Li-battery set, a motor, a power switch electrically connected between the motor and the electric power storage device and operable to switch on/off electric connection between the motor and the electric power storage device, a speed reducing gear set coupled to the output shaft of the motor, and an impact mechanism movable in a predetermined direction by the speed reducing gear set. When the power switch is switched on to electrically connect the electric power storage device to the motor, the motor is started to rotate the output shaft and the speed reducing gear set, causing the speed reducing gear set to move the impact mechanism and to further provide an impact force. | 02-12-2009 |
