Embodiment
Consult shown in Fig. 1 to Fig. 3, the secondary Assembled battery of a kind of tool overcharge electric discharge device that the embodiment of the present invention provides, it is mainly made up of battery box 20, heating panel 30, overcharge electric discharge device 40, multiple first joint 50 and multiple second joint 60, wherein:
This battery box 20, for metal material makes and have good heat-sinking capability, and has a storage tank 21 arranged for multiple secondary cells 10; In the present embodiment, lifting storing four secondary cells 10 is example, and this battery box 20 has more an outer surface 22 and two is convexly equipped in this outer surface 22 and has the first joint portion 23 of a distance apart.
This heating panel 30, for metal material makes and have good heat-sinking capability, and is installed in this battery box 20; In the present embodiment, this heating panel 30 has one and is arranged on this heating panel portion 31 and the second joint portion 32 be combined with this first joint portion 23 respectively with this battery box 20 outer surface 22 at a distance of the heating panel portion 31 and two of a distance, makes this heating panel 30 and this battery box 20 jointly define a heat-dissipating space 33 that can pass through for fluid.And this first and second joint portion 23,32 is through screw 34 be combined with each other integral.
This overcharge electric discharge device 400, be located at this battery box 20, and have should secondary cell 10 quantity and be electrically connected the overcharge electric discharge module 40 of respectively this secondary cell 10, and respectively this overcharge electric discharge module 40 comprises one in order to consumes power and is installed in the balance resistance of this heating panel 30; In the present embodiment, respectively this balance resistance is cement resistor 41, and respectively this cement resistor 41 is fixedly arranged on this heating panel 30 heating panel portion 31 and is positioned at this heat-dissipating space 33, and have one and stick to lock by screw 42 in the heat transfer face 411, two of this heating panel 30 and establish portion 412 and multiple radiating groove 413 at the lock of this heating panel 30.
Respectively this first joint 50, is electrically connected at respectively this overcharge electric discharge module 40.
Respectively this second joint 60, is electrically connected at respectively this cement resistor 41 and can be incorporated into respectively this first joint 50 with separating.
The above is embodiment of the present invention main member and configuration explanation thereof.Effect as the embodiment of the present invention makes the following instructions.
Make because this battery box 20 and heating panel 30 are all metal material and there is good heat-sinking capability, therefore, when each this secondary cell 10 is when carrying out producing overcharge condition in the process of charging, the heat energy that respectively this secondary cell 10 produces is able to be absorbed by the battery box 20 that metal material is made and is removed in ambient air by surface is loose by heat energy, thus reduces the temperature that respectively this secondary cell 10 produces when charging fast, again when each this secondary cell 10 is when carrying out producing overcharge condition in the process of charging, the cement resistor 41 of this overcharge electric discharge module 40 can carry out electric quantity consumption, now, this cement resistor 41 is except the structural design by each radiating groove 413 itself, and by loose for heat energy converted for electric energy except to ambient air, more heat energy can be transmitted to this heating panel 30 through heat transfer face 411, the heat energy allowing this heating panel 30 take away rapidly this cement resistor 41 to produce, and heat energy is loose except in ambient air by the surface of heating panel 30, thus the temperature of this cement resistor 41 is reduced fast, accordingly, the present invention mainly uses the arrange in pairs or groups heating panel 30 of metal material and the cement resistor 41 of selecting power higher of the battery box 20 of metal material to be located on this heating panel 30, make this secondary Assembled battery must can not have preferably radiating effect in the process of overcharge electric discharge via the structural design of complexity, to avoid affecting charging effect, simultaneously greatly reduce Yin Gaore and produce the possibility of blast.
It is worth mentioning that, because the present invention employs the larger cement resistor of power 41 in design, and collocation is the battery box 20 that metal material makes and have good heat-sinking capability and the heating panel 30 that arranges for each this cement resistor 41, therefore, must additional designs cooling system, comparatively simple and easy and do not affect radiating effect in making and design.
Secondly, due to respectively this cement resistor 41 being located at this heating panel 30 be through this second joint 60 and be electrically connected at discharge the first joint 50 of module 40 of this overcharge and connect, and this first joint 50 and this second joint 60 are the configurations in can mutually separating and combine, therefore, in maintenance and assembling comparatively facility.
What deserves to be explained is, this overcharge electric discharge device 400 has more the circuit board body 401 being located at this battery box 20 storage tank 21 notch, and this circuit board body 401 supplies respectively this overcharge electric discharge module 40, and respectively this secondary cell 10 is electrically connected setting, and respectively this overcharge electric discharge module 40 more comprise one as discharge switch semiconductor switch 43, and a pair this secondary cell 10 carries out the detecting voltage unit 44 of detecting voltage, due to this detecting voltage unit 44, and this semiconductor switch 43 to make flowing mode identical with known, therefore repeat no more, again this circuit board body 401 has more positive pole cartridge 402 and a negative pole head 403, using the power output end as secondary Assembled battery.
In sum, this embodiment and diagram are only preferred embodiment of the present invention, when can not with restriction the scope of the present invention, the equalization namely generally done according to the present patent application the scope of the claims change with modify, all should remain within the scope of the patent.
