The object of the application realizes like this, a kind of rechargeable battery elastic connection plate structure of applicable capacity safe charging, it is characterized in that: at least comprise elastic connection plate, described elastic connection plate is connected by spring lever assembly with between electric lids, limited location groove on elastic connection plate, elastic connection plate is moved up and down in stopper slot scope of activities, keep-spring bar assembly elasticity; The anode output-parallel of each element cell is connected to the positive electrode of electric lids by the positive electricity end of elastic connection plate, and the negative terminal output-parallel of each element cell is extremely connected to the negative electrode of electric lids by elastic connection plate negative electricity.
The anode of described element cell exports and negative terminal output to be connected with elastic connection plate be that steel ball by interface board is flexibly connected, steel ball is embedded in the steel bead groove of interface board, have spring in steel bead groove, steel bead groove is young in diameter of the steel ball D, and steel ball is coated with metallic conductor.
At least comprise a surcharge plate, surcharge plate is flexibly connected with elastic connection plate lower surface, be flexibly connected with the conductor steel ball of interface board upper surface, for the output of the anode of each element cell and negative terminal are exported by being connected in series, surcharge plate positive and negative electrode interface after being connected in series is connected with charger, and charger is to all element cells chargings after being connected in series.
Have a removable cover in the housing upper end of encapsulation unit battery, removable cover has electrode via hole, and removable cover is socketed in the housing upper end of encapsulation unit battery, the gap between removable cover surrounding plate washer sealed elastic connecting plate and interface board.
The advantage of the application is: the positive and negative electrode of element cell is connected to electric lids by elastic connection plate transition.Comprise a surcharge plate, surcharge plate is flexibly connected with elastic connection plate lower surface, be flexibly connected with the conductor steel ball of interface board upper surface, for the output of the anode of each element cell and negative terminal are exported by being connected in series, surcharge plate positive and negative electrode interface after being connected in series is connected with charger, and charger is to all element cells chargings after being connected in series.Like this, when battery uses, low-voltage, current state is operated in.During charging, by surcharge plate, battery strings is connected into the monomer battery structure of multiple low current charge, can quick charge, can service time of battery be extended again, reduce charger cost.
