Description
Technical field
The utility model is related to battery apparatus technical field of measurement and test, more particularly to a kind of battery dump energy test device.
Background technology
Battery is a kind of device that chemical energy is changed into electric energy.Different materials can produce different in chemical change
Electromotive force；Material is used up, electromotive force just without.But before material is used up, its purity just changes：Pole plate can polarize,
Electrolyte impurity can increase etc..These can all make inside battery with the presence of resistance, and with the increase of use time, resistance
Can be increasing, so as to influence the current output capability of battery.
Commonly using battery, and battery chaotic occasion easy to store, such as it can often use a large amount of batteries in laboratory.
If deposit battery it is irregular it is very possible by the different battery storing of various power consumptions together, it is also possible to infiltrate and exhausted
The battery of electricity.If an experimental facilities needs five pieces of No.5 cells, one piece therein does not have electricity to influence the normal of equipment yet
Operation.
General quantity measuring method is all measurement voltage, but this method is when also having insecure.Managed according to circuit
By any power supply includes battery, can be equivalent to preferable a voltage source and a resistance connected in series, voltage source is just
It is the electromotive force of battery.Measure cell voltage when, due to voltmeter internal resistance it is very big, what is measured is substantially electronic
Gesture.The internal resistance of cell is big or small all do not reflect of internal resistance is come.Only when battery uses the very old times, the internal resistance of cell substantially increases, voltage
Just it is decreased obviously.Thus the voltage for the used batteries that universal method is measured all is virtual height, once external load will drop.
And when surveying the short circuit current flow of battery, the internal resistance of universal meter is almost nil, current value is exactly in electromotive force divided by battery
The value of resistance.Current value is big, represents that electromotive force is high, internal resistance is small, and battery quality is good or battery electric quantity is sufficient；Electric current is small, represents that internal resistance is big
Or not only internal resistance is big but also electromotive force is low, battery electric quantity is not enough.Thus can be the electromotive force and the size of internal resistance of battery
Reflect simultaneously.
Based on this, the utility model proposes a kind of battery dump energy test device.It is intended to be measured by direct measurement
The electric current at battery two ends judges mesuring battary dump energy, and battery needed for quickly selecting oneself electricity consumption facility eliminates not
The battery that can be reused.
The content of the invention
The utility model is tested to make up the defect of prior art there is provided a kind of simple efficient battery dump energy
Device.
The utility model is achieved by the following technical solution：
A kind of battery dump energy test device, it is characterised in that：Including test bodies and universal meter, the test sheet
Body is realized by test interface with universal meter and is detachably connected；The test bodies include housing, described enclosure interior one end
It is provided with inside test resistance, the other end provided with test spring；When mesuring battary is placed in enclosure interior, its positive pole connecting test electricity
Resistance, negative pole connecting test spring；The test resistance and test spring pass through wire connecting test interface respectively.
The test resistance resistance is 0.1 Ω.
The test resistance uses internal resistance for 0.1 ohm of iron plate.
The test spring uses copper spring.
The battery dump energy test device is applied to the battery of each model, the dimensions of the housing with it is corresponding
The dimensions of the battery of model is adapted.
The beneficial effects of the utility model are：The battery dump energy test device, it is simple in construction, it is easy to connect, can be with
Fast and effeciently judge the dump energy of battery electric quantity, the loss that the battery that misuse electricity can not only be avoided to use up is caused, also
Operating efficiency can be improved, it is ensured that the normal operation of equipment.
Brief description of the drawings
Accompanying drawing 1 is the utility model battery dump energy test device schematic diagram.
In accompanying drawing, 1 housing, 2 universal meters, 3 test interfaces, 4 test resistances, 5 test springs.
Embodiment
In order that technical problem to be solved in the utility model, technical scheme and beneficial effect are more clearly understood, with
Under in conjunction with the accompanying drawings and embodiments, the utility model is described in detail.It should be noted that specific reality described herein
Example is applied only to explain the utility model, is not used to limit the utility model.
The battery dump energy test device, including test bodies and universal meter 2, the test bodies and universal meter
2 are detachably connected by the realization of test interface 3；The test bodies include housing 1, and described inside one end of housing 1 is provided with survey
Try inside resistance 4, the other end provided with test spring 5；When mesuring battary is placed in 1 inside of housing, its positive pole connecting test resistance 4,
Negative pole connecting test spring 5；The test resistance 4 and test spring 5 pass through wire connecting test interface 3 respectively.
The resistance of test resistance 4 is 0.1 Ω.
The test resistance 4 uses internal resistance for 0.1 ohm of iron plate.
The test spring 5 uses copper spring.
The battery dump energy test device is applied to the battery of each model, the dimensions and phase of the housing 1
The dimensions of the battery of model is answered to be adapted.
No. five new dry cell electric currents measured using the battery dump energy test device are probably in 3-5A, less than 0.3A
Left and right can just be eliminated, and relevant parameter can measure new battery in advance and be obtained with waste battery.
The battery dump energy test device is entered by digital multimeter direct measurement battery two ends electric current with universal meter
To accomplish that range is suitable during row short circuit measurement, the testing time is short, ensures that at 1-3 seconds data, universal meter can be read as far as possible
Test pencil need contacted with test point closely, to ensure that battery will not be because of short-circuit power down.
For example, surveying the short circuit current flow of No. 5 batteries, universal meter first can be put into 10A gears, then test the battery dump energy
The negative test pencil of device is connected, and positive test pencil is pressed into positive pole test point rapidly, while observing indicator or general-purpose meter reading.If reading
It can be parked in certain value 0.5~1 second, read this value, at once leave positive test pencil, test is just completed.If it was found that be possible to range,
Also test pencil is disconnected immediately, is put on some larger electric current gear, until measuring specific electric current.
