Below in conjunction with the drawings and specific embodiments, operation principle is described in further detail to type of the present invention:
Accompanying drawing explanation
Fig. 2 is the internal structure sketch of alkaline dry battery: 1, just very battery case is directly connected with manganese dioxide.2, manganese dioxide and salt ammonia carbon granules compound it have a large amount of positron, be positive pole supply positron.3, copper pin is welded in the equilibrium of negative plate middle guarantee copper pin at calamine cream cylindrical middle guarantee afflux negatron of battery.4, diaphragm case ensures that section body mutual insulating with positron-electron can not short circuit or electric leakage.5, calamine cream has a large amount of negatron, is negative pole supply negatron.6, negative pole is connected with copper pin, and the brief principle of alkaline dry battery is that battery starts electric discharge when positive and negative electrode is communicated with by load, should stop electric discharge, otherwise will damage battery when both end voltage arrives 0.8V.Can also be supplemented by the mode of charging after their positive and negative electronics of storing of the positive electrode (manganese dioxide) of battery and negative material (calamine cream) are finished and reach more than voltage 1.5V, reach the object of Reusability.As long as logical in a few years test of many times confirms that grasping charging current is successful crux.As charging current is large, negative material (calamine cream) can generate heat liquefy from pore outflow or generation gas burst.We are not more than 50mA at the circuit charging current of design, automatically stop charging when cell voltage reaches 1.85V.There is suburb to prevent battery-heating to cause the danger of flow liquid or blast like this, ensure that charging safety.Charging curve Fig. 3: we set battery charging voltage is 0.8V, and voltage reaches 1.5V fast within half an hour, then voltage starts slow rising, stops charging when reaching 1.85V.
Fig. 1 is the electrical schematic diagram of type embodiment of the present invention:
Embodiment
Circuit described in type of the present invention is installed and is used as a stand-alone product on a printed circuit, as can be seen from Figure 1, the negativing ending grounding of battery, the input negative terminal of the positive termination voltage comparator of battery, the intermediate ends of the positive termination RP1 of voltage comparator LM124, a termination+12V other end ground connection of potentiometer RP1, the output of voltage comparator LM124 passes through the base stage of resistance R2 connecting triode, and+12V voltage is through the collector electrode of light-emitting diode VL1 and resistance R2 connecting triode V1, the control principle of type of the present invention is: the positive voltage of battery deliver to voltage comparator ic 1 negative terminal at this moment positive terminal voltage higher than negative terminal voltage, the output of voltage comparator LM224 is high potential, through the base stage of resistance R1 to three poles, at this moment because base stage obtains the therefore conducting of high potential triode, power supply+12V leads to light-emitting diodes, resistance R2, triode charges to battery, Fig. 3 is charging voltage curve, general battery discharge charges to during 0.8V, charging is stopped when reaching 1.85V, this circuit parameter determines charging current and is no more than 50ma, cell voltage raises with charging, charged electrical fails to be convened for lack of a quorum and progressively reduces, charging is stopped when cell voltage reaches the positive terminal voltage value of IC2 (1.85V).
