Abstract
The utility model discloses a performance test device of a lithium battery protective board, which is matched with the battery protective board and an external computer to use and comprises a voltage source and a current source, wherein the voltage source is connected with the external computer and is controlled by the external computer to give out specified voltage which is used for simulating the voltage of an electric core in the lithium battery; the current source is connected with the external computer and is controlled by the external computer to give out specified current which is used for simulating the current of the lithium battery when in practical application; and the voltage source, the current source and the battery protective board are connected. When in use, the voltages of relevant points of the lithium battery protective board are measured so as to judge the work state of the lithium battery protective board; a power module corresponding to the current source is used for simulating the situation that no current flows through the voltage source of the electric core of the lithium battery, so that the corresponding power loss is avoided and the power consumption of the performance test device is greatly reduced; and since the current output by the current source only flows through one end of a sampling resistor of the lithium battery protective board, the risk of burning down the measured lithium battery protective board during measurement is greatly reduced.
Description
Technical field
The utility model belongs to the lithium battery testing apparatus, specifically is meant the device of testing at li-ion cell protection plate performance.
Background technology
Along with the upgrading day by day of electronic product, the expansion of usable range has had new requirement again for the quantity and the quality of lithium battery, therefore, must carry out more detailed comprehensive test to the electric core and the fender of lithium battery.Traditional li-ion cell protection board test instrument has been connected on the whole protecting plate in the circuit; the li-ion cell protection template die has been intended true operating position; but electric current flows through the whole protecting plate during test; probably the metal-oxide-semiconductor in the fender or other devices are burnt out when electric current is excessive; electric current is through the testing tool voltage source; can consume very big electric work, increase the power of whole lithium battery testing tool, improve the production cost of lithium battery.
The utility model content
The purpose of this utility model is to provide a kind of li-ion cell protection plate performance testing device, and it can simplify the power consumption of li-ion cell protection board test instrument under the prerequisite that keeps environment for use that is virtually reality like reality, simultaneously, reduce the damage to the test fender.
For achieving the above object, the utility model adopts following structure:
A kind of li-ion cell protection plate performance testing device, matching battery fender and external computer use, wherein: voltage source and current source, described voltage source links to each other with external computer, its control of accepting external computer provides given voltage, is used for simulating the electric core voltage in the lithium battery; Described current source links to each other with external computer, and it accepts the electric current that external computer control provides appointment, the electric current when simulating the lithium battery practicality thus; Described voltage source, current source link to each other with battery protecting plate.
Preferably, above-mentioned current source is connected between the P-end and C-end of li-ion cell protection plate.
Preferably, above-mentioned battery protecting plate is provided with sampling resistor, and described sampling resistor is located between P-end and the C-end.
After adopting said structure; during use; though electric current has only passed through the fender of half; because the sampling resistor of electric current is between P-end and C-end in the li-ion cell protection plate; the li-ion cell protection plate is still thought has electric current to flow through entire cell; measure the voltage of measurement of correlation point on the li-ion cell protection plate then by the utility model, to judge the duty of li-ion cell protection plate.After this changes; the corresponding power module of having only current source in the utility model; the voltage source that is used for simulating lithium battery electric core does not have electric current to flow through; just there has not been corresponding power attenuation yet; significantly reduced power consumption of the present utility model; because the electric current of current source output has only flow through sampling resistor one end of li-ion cell protection plate, greatly reduces the risk that burns out tested li-ion cell protection plate when measuring.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Embodiment
With reference to shown in Figure 2, the utility model discloses a kind of li-ion cell protection plate performance testing device, matching battery fender 3 uses, and it comprises voltage source 1, current source 2, wherein:
Voltage source 1 links to each other with battery protecting plate 3, and it also is circumscribed with computer, and its control of accepting external computer provides the voltage of appointment, is used for simulating the electric core voltage in the lithium battery;
During use; though electric current has only passed through the fender of half; because the sampling resistor 31 of electric current is between P-end and C-end in the li-ion cell protection plate 3; li-ion cell protection plate 3 is still thought has electric current to flow through entire cell; measure the voltage of measurement of correlation point on the li-ion cell protection plate then by the utility model, to judge the duty of li-ion cell protection plate.After this changes; the corresponding power module of having only current source in the utility model; the voltage source that is used for simulating lithium battery electric core does not have electric current to flow through; just there has not been corresponding power attenuation yet; significantly reduced power consumption of the present utility model; because the electric current of current source output has only flow through sampling resistor one end of li-ion cell protection plate, greatly reduces the risk that burns out tested li-ion cell protection plate when measuring.
Though described the utility model by this embodiment, those of ordinary skills know, surface patterns of the present utility model and size have many distortion and variation and do not break away from spirit of the present utility model, wish that appended claim comprises these distortion and variation and do not break away from spirit of the present utility model.
