The lithium battery of this application is as shown, and its inside a plurality of lithium battery monomer all have two arc parcel centre gripping to lithium battery monomer's heat conduction to arc department to by conduction to cooling tube department, form a plurality of radiating air flows through the cooling tube between two tip units, radiating air flow circulates between cooling tube and circulation channel, thereby takes away lithium battery monomer's heat. In addition, due to the arrangement of the supporting plate and the supporting spring, the supporting plate and the supporting spring can well support a plurality of lithium battery monomers, so that the purpose of shock absorption is achieved. However, when the lithium battery cell cannot be tightly clamped by the arc plate, heat cannot be effectively conducted, so that the state of the lithium battery cell needs to be detected. Through set up the pressure sensor that holds the board and be a plurality of rectangular array distribution in bottom department, when certain lithium cell monomer appears falling from battery clamping position, can strike and hold the board to pressure sensor's measured value is unusual, consequently can report to the police and remind the maintenance, this is a long-term passive monitoring method. The detection can be actively performed, the air pump is used for injecting air into the cavity unit, so that a plurality of movable rods move downwards and are inserted into the positioning holes, and along with the extension of the movable rods, the two end units move downwards, so that all the battery units move downwards integrally, the bearing plate is pressed downwards, whether the height distribution of the battery units distributed in the rectangular array before being pressed downwards is abnormal or not can be judged according to the measured value of the sensor distributed in the rectangular array (for example, when the position of a corresponding arc plate of a certain battery unit moves downwards before), and then the measured value of the pressure sensor distributed in the rectangular array is abnormal (particularly, the measured value of a certain pressure sensor is obviously larger than the measured value of other pressure sensors). In addition, when a certain movable rod cannot be matched with a corresponding positioning hole for positioning, the measured values of the pressure sensors distributed in the rectangular array are abnormal, so that the positions of a plurality of lithium battery units and whether the positions of two end units are normal can be judged through active detection.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the scope of the invention as defined in the following claims.
