Description
Technical field
The utility model relates to a kind of storage battery, relates in particular to a kind of high temperature power-off protection storage battery.
Background technology
Chemical energy converts the device of electric energy to chemical cell, generally referred to as battery.After battery discharge, can make inner active material regeneration by the mode of charging, be chemical energy electrical power storage; Need to discharge time, again chemical energy is converted to electric energy.This class battery is called to storage battery, also claims secondary cell.But find in the process charging a battery for a long time, existing this type of battery is easily heating expansion in the time of charging, and therefore battery explosion phenomenon easily occurs.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of high temperature power-off protection storage battery that can auto-breaking at charging adstante febre.
For solving the problems of the technologies described above, the utility model provides a kind of high temperature power-off protection storage battery, comprises battery body, on described battery body, is provided with protective device; Described protective device comprise the first electrode of being fixedly installed, with the second electrode and electromagnet that described the first electrode elastic contacts, after described electromagnet energising, can adsorb described the second electrode described the second electrode and described the first electrode are separated; Described electromagnet is electrically connected with controller, and described controller is connected with the heat sensor that is arranged at described battery body inside.
The two ends of described the second electrode are connected with respectively flexible member.
Described flexible member is helical spring.
The rectangular metal sheet that described the first electrode and described the second electrode are sheet, described the first electrode is positioned at the top of described the second electrode, and described electromagnet is positioned at the below of described the second electrode.
The beneficial effects of the utility model are: because high temperature power-off protection storage battery of the present utility model is provided with protective device, in charging process, the first electrode of protective device contacts with the second electrode elastic, charging circuit conducting, the temperature of heat sensor monitoring battery, when the temperature signal that controller receives will be switched on to electromagnet during higher than safe temperature, after electromagnet energising, absorption the second electrode is separated the second electrode and the first electrode, cut off charging circuit, thereby interrupt charging, prevent that battery is because of the overheated explosion of charging, simple in structure, easy to use, therefore the utility model can be protected storage battery by auto-breaking at charging adstante febre.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: battery body 2, positive terminal 1, negative terminal 3, protective device 4, flexible member 6, the first electrode 21, the second electrodes 22, electromagnet 23, controller 24, heat sensor 25.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details: shown in Figure 1, a kind of high temperature power-off protection storage battery of the present utility model, comprise battery body 2, on this battery body, there is positive terminal 1 and negative terminal 3, on battery body 2, be provided with protective device 4; This protective device 4 comprises the first electrode 21, the second electrode 22, electromagnet 23, controller 24 and heat sensor 25; wherein the first electrode 21 and the second electrode 22 are the rectangular metal sheet of sheet; and the first electrode 21 is fixedly installed; under the effect of the flexible member 6 that the second electrode 22 that is positioned at the first electrode 21 belows connects at its two ends with the first electrode 21 Elastic Contact; one electromagnet 23 is installed under the second electrode 22; this electromagnet 23 is electrically connected with controller 24, and controller 24 is connected with the heat sensor 25 being arranged in battery body 2.
Use principle of the present utility model is: the first electrode 21 of protective device 4 and the second electrode 22 Elastic Contact in charging process; charging circuit conducting; heat sensor 25 is monitored the temperature of battery and temperature signal is fed back to controller 24; the temperature signal receiving when controller 24 will be switched on to electromagnet 23 during higher than safe temperature; after electromagnet 23 energisings, producing magnetic force and adsorbing the second electrode 22 makes the second electrode 22 21 separate mutually with the first electrode; interrupt charging thereby cut off charging circuit, therefore can effectively prevent that storage battery is because of the overheated explosion of charging.
The foregoing is only preferred embodiments of the present utility model; protection range of the present utility model is not limited with above-mentioned execution mode; in every case the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or is changed, and all should include in the protection range of recording in claims.
