Background technology
Along with the application on electric vehicle and large-scale energy storage device of secondary cell, especially secondary lithium battery more and more widely, series connection uses the occasion of battery also more and more.Under the situation that the battery series connection is used, battery greatly affects the capacity performance of the whole group of battery and the life-span of electric battery from the consistance of power consumption.
The combined electrical core need carry out the consumable electrical testing to all composition electricity cores.Yet there are following defective in present battery consumable electric test device and method: need wear out after the electric core charging, more electric core is discharged, and then charging.Wherein, aging needs have taken the processing procedure time after shelving and not waiting to the several months in several days; Change into cabinet in the test process and electric core all has power consumption.By on can know that prior art is because the consumption of time and energy has all increased electric core manufacturing cost.
Summary of the invention
The purpose of the utility model is to provide a kind of simple test fast secondary cell, the especially secondary lithium battery test macro from consumption rate, is used for electric core consumable electrical measurement, substitutes present consumable electrical testing technology.
To achieve these goals, the utility model adopts following scheme:
A kind of quick test secondary cell is characterized in that from the system of consumption rate: comprise standard electric core, electric core shunting means, single electrode short-circuiting means and reometer; Electricity core shunting means also has with all standard electric cores and all electric core parallel connections to be tested and with the electrical connection mechanism of both positive and negative polarity short circuit; Electricity core single electrode short-circuit device has the electrical connection mechanism that connects the single standard electric core and the same utmost point of single electric core to be measured and two terminals that are connected single another utmost point of standard electric core and single electric another utmost point of core to be measured respectively, connects reometer between two terminals.
Said standard electric core comprise some electric cores from consumption rate according to each one in the 1% electric core that successively decreases.
Said electric core shunting means has arranges some standard electric cores placement positions and the electric core placement to be tested position that is provided with.
Electricity core single electrode short-circuit device has the standard electric core and places position and electric core placement to be tested position.
The utility model uses known to consumption rate standard electric core; Size through electric core more to be measured and standard electric core from consumption rate; Judge the scope from power consumption of electric core to be measured; Reach through aging technique and test the effect of electric core, saved the time and the cost of electric energy of battery sorting combo from power consumption.
Description of drawings
Standard electric core and the parallelly connected synoptic diagram of electric core to be measured that Fig. 1 provides for embodiment.
Fig. 2 tests the synoptic diagram from the power consumption scope for utilization electricity core single electrode short-circuit device and reometer that embodiment provides.
The system that Fig. 3 provides for embodiment is at the process flow diagram of test from power consumption.
Embodiment
The quick test secondary lithium battery that present embodiment provides comprises from the system of consumption rate: standard electric core, electric core shunting means, electric core single electrode short-circuit device and reometer.
Wherein, from a large amount of electric cores, pick out electric core from consumption rate according to each one in the 1% electric core that successively decreases, for example pick out electric core from consumption rate be 97%, 96%......86%, each one in 85% electric core is as the standard electric core.As shown in Figure 1, electric core shunting means has that the standard electric core that arrange to be provided with is placed position 11 and electric core to be tested is placed position 12, and electric core shunting means also has all standard electric cores and all electric cores to be tested is in parallel and with the electrical connection mechanism 13 of both positive and negative polarity short circuit.As shown in Figure 2; Electricity core single electrode short-circuit device has the standard electric core and places position and electric core placement to be tested position; Electricity core single electrode short-circuit device also has the electrical connection mechanism 21 that connects single standard electric core negative pole and single electric core negative pole to be measured and is connected anodal 22 the connection reometers of 22, two terminals of two terminals of the anodal and single electric core to be measured of single standard electric core respectively; Certainly; The structure of electricity core single electrode short-circuit device also can be to have two terminals that connect the anodal electrical connection mechanism of the anodal and single electric core to be measured of single standard electric core and be connected single standard electric core negative pole and single electric core negative pole to be measured respectively, and effect is identical.
In conjunction with shown in Figure 3; The quick test secondary lithium battery that the foregoing description provides is following from the principle of work and the method for application of the system of consumption rate: will treat the electric core (also being the some electric core of tape test) of combo, and charge to identical voltage together with the standard electric core, will treat that then pack into the standard electric core of electric core shunting means of combo electricity core and standard electric core places position and electric core to be tested and place; It is together in parallel; Shelve a period of time,, make the voltage basically identical between the battery such as two hours; Afterwards; Remove electric core shunting means; Utilize electric core single electrode short-circuit device with standard electric core and electric core negative pole short circuit to be measured, use reometer that the positive pole of electric core to be tested and standard electric core is coupled together, judge that through current value and direction of current battery is from the power consumption scope.
The quick test secondary lithium battery that present embodiment provides from the system of consumption rate compared with prior art; Have following advantage and beneficial effect: during from power consumption, digestion time is in one day at the electric core of test, and weak point can be one hour; More traditional consumable electric test method has been practiced thrift the time; Again battery is discharged and recharged after traditional consumable electric test method need wear out, use the utility model can omit this operation, practice thrift the power consumption that produces owing to test in producing, reduced the production cost of battery.
