Embodiment
As shown in Figure 1, for the disclosed electrolytic solution of the present invention overflows the structural representation of pick-up unit, it is mainly used in an energy storage device, for example electrolytic cell or electrolytic condenser.
Electrolytic solution overflows pick-up unit and mainly overflows test section 20 by one and form.Overflowing test section 20 optionally is arranged on one first carrier 10.This electrolytic solution overflows pick-up unit, and can to adhere to or be pasted on the basis of electrolytic cell or electrolytic condenser external.When overflowing test section 20 and contacting, change so that overflow the impedance of test section 20 with the excessive electrolytic solution of electrolytic cell or electrolytic condenser.
After being changed, impedance can go out by electric circuit inspection, overflow test section 20 and be connected with couple of conductor 30, lead 30 includes lead 31,32, and join with testing circuit, make can be by being connected with lead 30 testing circuit (will in following explanation) can when the impedance of overflowing test section 20 changes, this impedance change state be become the electric power signal output of voltage pattern or electric current pattern.
In the use, the energy storage device that the embodiment and in [Fig. 1] is had electrolytic solution contacts, and this has the energy storage device of electrolytic solution, and for instance, can be battery, electric capacity maybe need be with the generator of liquid fuel etc.
First carrier 10 can be a plastic tab, dry goods, polymkeric substance (polymer) or the scraps of paper.On Material Selection, need to tolerate the variation of overflowing test section 20 and can not produce chemical reaction with electrolytic solution.Carried by the carrier of sheet form owing to overflow test section 20, so the disclosed electrolytic solution of the present invention overflows on the body that pick-up unit can be attached directly to battery or electric capacity.But first carrier 10 is also inessential, can select for use by the material that test section 20 is overflowed in suitable selection.
Produce impedance variation when overflowing test section 20 and contacting with the electrolytic solution that overflows.Its arrangement mode can be with a line mode, two non-intersecting lineses or the two-layer up and down not film of contact.Can be a line mode shown in the figure for instance.
Overflow the material of test section 20, can select the test paper of unlike material for use or try cloth as the instrument that detects the battery module electrolyte leakage, its principle mainly is to utilize when electrolytic solution to be adsorbed on test paper or examination cloth when surperficial, and the resistance value detected signal that changes is reached above-mentioned purpose.
Selected test paper or examination cloth material are under dry condition, and resistance value is all quite big, and for example kilohm to more than the megohm, when electrolytic solution adsorb, resistance can be anxious according to dropping to less than below 100 ohm.
Following table is the variation of resistance under the test paper that detects as electrolyte leakage with unlike material or its drying regime of examination cloth and behind the absorption electrolytic solution.
| Material | Impedance under the drying regime | Impedance under the absorption electrolytic solution |
| PH test paper (PH test paper) | Greater than kilohm | Less than 100 ohm |
| 3M adhesive-bonded fabric fiber (3M nonwoven fabric) | Greater than megohm | Less than 100 ohm |
| General paper (paper) | Greater than megohm | Less than 100 ohm |
As long as test paper that is adopted or examination cloth have diffusivity and perviousness, and resistance is more than k ohm, owing to the electrolyte conductivity height, when being adsorbed on test paper or the examination cloth under the drying regime, the capital produces signal because of the urgency of impedance according to change, just can be as the test material of electrolyte leakage.As long as any test paper or its impedance value of examination cloth can change, all can be used as the test material of electrolyte leakage under dry condition and under the absorption electrolysis situation.
As shown in Figure 2, be the embodiment of a testing circuit, it is exported in order to when the impedance of overflowing test section 20 changes this change state is become voltage or current signal.Testing circuit 40 mainly is made up of a comparer 41, and its two input end is connected to lead 31,32 respectively.In addition, also has the required resistance of some circuit runnings, for example resistance 42, resistance 43, resistance 44, resistance 45.After the impedance of overflowing test section 20 changes,, overflow test section 20 and can be connected in resistance 42,43,44,45 wherein arbitrary positions by the connection of lead 31,32 and resistance 42,43,44,45.Because test section 20 produces impedance variation, make two input ends of comparer 41 sense the voltage change, and export an electronic signal in output terminal.
Testing circuit shown in Fig. 2 can be arranged on one second carrier (among the figure not formula).In one embodiment, can be a kind of flexible printed wiring board of second carrier.In another embodiment, can be arranged on the identical carrier with testing circuit overflowing test section 20.
The output terminal of comparer 41 connects a holding circuit (not shown), can be provided with a switch that can be subjected to the control of this electronic signal in this holding circuit, and MOSFET for example perhaps is provided with the protecting component of fuse for example etc.When the impedance that test section 20 is overflowed in the electronic signal representative of being exported when comparer 41 changes, represent that promptly electrolytic solution overflows, can cut off the running of system this moment by the effect of holding circuit.For instance, comparer 41 can become this change transitions the electronic signal of one voltage form after impedance changes, to control a switch.When if energy storage device or electric capacity are connected with an electronic circuit or power supply, this switch receives the signal that impedance changes, and switch can cut off the path between energy storage device or the electric capacity immediately and form and open circuit, and can prevent the accident generation.
Cooperate Fig. 1 and the disclosed embodiment of Fig. 2, can be during fabrication energy storage device or electric capacity be overflowed pick-up unit with the disclosed electrolytic solution of the present invention and contact.When the electrolytic solution in energy storage device or the electric capacity overflows, can contact with the test section that overflows that electrolytic solution overflows in the pick-up unit immediately, this overflows test section can produce chemical change with electrolytic solution, and its resistance can change behind the generation chemical change, and is exported by lead.By the comparer in the testing circuit, under normal condition with under the unusual condition, send different voltage signals respectively.
The disclosed embodiment of Fig. 1 and Fig. 2 can be made into one during fabrication, with suit part kenel so that the user can directly be attached on energy storage device or the electric capacity.In another embodiment; Fig. 1 is the part that separates with the disclosed embodiment of Fig. 2; that is, can be together with the circuit design of testing circuit and holding circuit part and an external system, the user only needs that electrolytic solution is overflowed pick-up unit and directly is attached on energy storage device or the electric capacity and gets final product.
The disclosed embodiment according to the present invention, it makes it produce impedance variation when contact electrolytic solution by the chemical constitution of a special composition.By this impedance variation; detection by an electronic circuit when it can the electrolytic solution in device overflows produces an electronic signal; the electronic circuit blocking-up that will be connected with device by this electronic signal and then by a holding circuit is avoided it to continue running and is caused the damage of electronic circuit or device.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; being familiar with those of ordinary skill in the art ought can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
