20150086832 | Battery pack injected with phase change material - The present invention provides a battery pack injected with phase change material, comprising a plurality of battery modules consisting of a plurality of stacked battery cells and a pack case housing the battery modules. The battery pack is hermetic, and injected with hydrofluoroether. The pressure in the pack case is between −0.09 MPa and −0.01 MPa. | 03-26-2015 |
20130183552 | BATTERY PACK SYSTEM AND LIQUID LEAKAGE DETECTION METHOD THEREOF - A battery pack system and a liquid leakage detection method thereof are provided. The battery pack system comprises battery cells, a isolated liquid and a battery box containing the isolated liquid. The battery cells are soaked in the isolated liquid. The battery box is formed with a isolated liquid outlet and a isolated liquid inlet. The outlet is connected together with the inlet via a circulation pump and a liquid separation device to form a circulation passage. When electrolyte leakage occurs to any of the battery cells, the electrolyte is separated into the liquid separation device and detected by a detection component. The present disclosure encloses the leaked electrolyte into the fire-retardant isolated liquid to prevent the electrolyte from contacting with the air so as to improve the safety of the battery box body. | 07-18-2013 |
20130181826 | BATTERY PACK AND LIQUID LEAKAGE DETECTION METHOD THEREOF - A battery pack and a liquid leakage detection method thereof are provided. The battery pack comprises a plurality of battery cells, a isolated liquid and a battery box containing the isolated liquid. The battery cells are soaked in the isolated liquid. The battery box comprising a box body and a cover plate. The isolated liquid is a fire-retardant and insulating liquid that has a specific gravity smaller than an electrolyte and is insoluble in the electrolyte. A collection portion is disposed at the bottom of the battery box, and a detection component is disposed in the collection portion. The present disclosure encloses the leaked electrolyte in the fire-retardant isolated liquid and uses the detection component to detect a resistance value of the isolated liquid so as to improve the safety of the box body. | 07-18-2013 |
20120251891 | Lithium-Ion Battery - A lithium-ion battery comprises a positive electrode, a negative electrode, an electrolyte system and an ion-selective conducting layer disposed between the positive electrode and the negative electrode. The ion-selective conducting layer consists of high polymers and an inorganic lithium salt having lithium-ion conductivity, or consists of the inorganic lithium salt. The inorganic lithium salt includes Li | 10-04-2012 |
