Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1, is the structural representation of the first embodiment of the active device of battery of the present utility model.This active device 100 comprises that high frequency pumping produces group testing circuit 120, coupling capacitance 130 and comparator 140 in circuit 110, battery.Wherein, comparator 140 can adopt the single-chip microcomputer that the model of American TI (Texas Instruments, Texas Instruments) is TMS320F28034PNQ.
Coupling capacitance 130 is connected on battery 200 and high frequency pumping produces between circuit 110.Internal resistance of cell testing circuit 120 is connected with battery 200.Comparator 140 produces circuit 110 with high frequency pumping respectively, internal resistance of cell testing circuit 120 is connected.Particularly, the input of comparator connects internal resistance of cell testing circuit 120, and the output of comparator connects high frequency pumping and produces circuit 110.
Internal resistance of cell testing circuit 120 is for detection of the current internal resistance value of battery, and this resistance value is converted into voltage signal feeds back to comparator 140.Particularly, high frequency pumping is connected between the positive pole and negative pole of battery 200 after producing circuit 110 and coupling capacitance 130 series connection, and internal resistance of cell testing circuit 120 is connected between the positive pole and negative pole of battery.
Comparator 140, in the time that the battery that receives extraneous transmission is enabled signal, obtains the current internal resistance value of battery 200 by internal resistance of cell testing circuit 120; And current internal resistance value and preset standard value are compared; When current internal resistance value is greater than preset standard value, control high frequency pumping generation circuit 110 and send radio-frequency excitation pulses signal to battery 200, with activated batteries 200, specifically, comparator is in the time relatively obtaining current internal resistance value and be greater than preset standard value, meeting conducting high frequency pumping generation circuit 110 is connected with its power supply, it is worked on power, thereby send radio-frequency excitation pulses signal to battery.The frequency of radio-frequency excitation pulses signal should be greater than 1 megahertz.In addition, comparator 140 is also in the time that current internal resistance value is greater than preset standard value, obtain the internal resistance of battery by internal resistance of cell testing circuit, when the internal resistance value of battery is less than after preset standard value, control high frequency pumping generation circuit and stop sending radio-frequency excitation pulses signal to battery.
