Current values and voltage values of the battery single bodies can be tested extremely conveniently through the current testing clamp, the current testing clamp has convenience and accuracy in testing, and the testing box can be expanded according to the testing requirements.
Description
Technical field
The utility model relates to the improvement technology of the testing tool of electric battery.
Background technology
The characteristics such as at present emerging lithium ion battery has that capacity is large, self-discharge rate is little, specific energy is high, memory-less effect, security are good are widely used in electric automobile and energy storage field.In order to study and verify the particular capacity of battery, need the concrete discharge curve of test battery, there is not at present the capacity of the measurement battery that suitable testing apparatus can be quantitative, can not test the variation of curent change and the capacity of every batteries.
The utility model content
In view of this, the technical problems to be solved in the utility model provides a kind of battery cell monomer testing current anchor clamps of being convenient to test battery electric current, voltage.
In order to solve the problems of the technologies described above, this technical matters adopts following solution:
A kind of battery cell monomer testing current anchor clamps, comprise be used to the test casing that battery cell to be tested is installed, Battery case inside is provided with positive lead and the negative lead of difference connecting single batteries positive pole and negative pole, each positive lead is all connected with corresponding shunt by copper bar, and each shunt links to each other with the external discharge loop.
And each negative lead concurrent connects in the described test casing.Each battery cell that is installed in the Battery case is set up in parallel.
The utility model can very conveniently test out current value, the magnitude of voltage of each battery cell of battery, and convenient test is accurate, and can be according to test needs extend testing casing.
Description of drawings
Fig. 1 is the utility model embodiment synoptic diagram.
Embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with embodiment the utility model is described in further detail:
As shown in Figure 1.The battery cell monomer testing current anchor clamps that present embodiment discloses can detect electric current, the magnitude of voltage of 6 batteries monomers simultaneously in real time, obtain over time curve of battery current, voltage, capacity thereby draw.
Specifically, these battery cell monomer testing current anchor clamps comprise that be used to the test casing 1 that battery cell to be tested is installed test casing 1 can hold 6 each battery cell arranged side by side.Be provided with positive lead and the negative lead of difference connecting single batteries positive pole and negative pole in Battery case 1 inside, each positive lead is all connected with corresponding shunt 3 by copper bar 2, and each shunt 3 links to each other with the external discharge loop.During connection, each negative lead concurrent connects in the test casing 1.
The discharge current of battery cell can be measured its variation by shunt, and is recorded by the foreign current detection system and to pass through external display device shown, and the foreign current detection system has voltage checking chip, can detect battery cell voltage.The tester can calculate the variation of the capacity of battery according to the variation of electric current and the voltage of battery cell, thereby can draw respectively the electric current of battery cell with the change curve (U-I curve) of voltage, the capacity change curve (Q-U curve) with voltage.
Above-described embodiment only is wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
