Below in conjunction with accompanying drawing, the embodiment of the present invention a kind of busbar temperature rise method for evaluating consistency and device are described in detail.
In description of the invention, it will be appreciated that, orientation or the position relationship of the indications such as term " " center ", " on ", D score, 'fornt', 'back', " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", " outward " be based on orientation shown in the drawings or position relationship; be only the present invention for convenience of description and simplified characterization; rather than the device of indication or hint indication or element must have specific orientation, with specific orientation structure and operation, so can not be interpreted as limitation of the present invention.
With reference to Fig. 1, the described busbar temperature rise of embodiment of the present invention method for evaluating consistency comprises the following steps:
S1, choose one group of busbar to be measured, each busbar in one group of busbar to be measured is all applied to the first electric current, Real-time Collection also records the temperature parameter of each busbar;
S2, according to the temperature parameter of record, calculate the temperature rise value of each busbar when the first electric current;
S3, according to the temperature rise value of each busbar, calculate the average temperature rising value of one group of busbar to be measured;
S4, according to the average temperature rising value of the temperature rise value of each busbar and described one group of busbar to be measured, the temperature rise standard deviation while calculating described one group of busbar to be measured by the first electric current, the computing formula of temperature rise standard deviation is:
In formula: δ is the temperature rise standard deviation, and Tn is the temperature rise value when the first electric current for each busbar, the average temperature rising value that T is one group of busbar to be measured, and n is the busbar quantity in one group of busbar to be measured;
The consistance of S5, temperature rise while according to described temperature rise standard deviation, judging one group of busbar to be measured by the first electric current.
The busbar temperature rise method for evaluating consistency that the embodiment of the present invention provides, utilize standard deviation can reflect that a plurality of measurement data depart from these characteristics of degree of measurement data mean value, by the temperature rise standard deviation by the first electric current time the and preset standard is poor compares by one group of busbar, judge the consistance of one group of tested busbar temperature rise, because busbar temperature by electric current the time can raise, the serviceability of the battery that the temperature rise meeting impact of busbar connects by busbar, when one group of busbar temperature rise does not have consistance, illustrate that this organizes female temperature rise and differ greatly, excess Temperature when local busbar work easily occurs, thereby cause the unbalanced reduction of battery operated temperature battery life, when one group of busbar temperature rise has consistance, when this group busbar work is described, temperature rise difference is less, thereby can make battery operated temperature equalization can extend the serviceable life of battery, thus, can be whether qualified by the temperature rise consistance of estimating busbar, select to meet the busbar of request for utilization.
The method of the temperature rise value while calculating each busbar by described the first electric current comprises:
S21, the temperature when reading each busbar temperature no longer significant change occurring in by the first electric current process, i.e. equilibrium temperature;
The difference of the initial temperature of S22, the equilibrium temperature of calculating each busbar and each busbar, described difference is the temperature rise value of each busbar, initial temperature be described each busbar do not have electric current by the time temperature.
Because the temperature of busbar by electric current the time is dynamic change, initial temperature compared to each busbar, the temperature of each busbar rises gradually, a certain temperature in the busbar temperature uphill process and the difference of initial temperature are difficult to the whole process that reflects that busbar temperature rises, therefore, can be by calculating the difference of each busbar equilibrium temperature and initial temperature, thereby obtain the temperature rise value of each busbar, thus, the temperature rise value that calculates each busbar of gained can reflect the overall process of busbar temperature rise, thereby make can reflect more accurately according to the temperature rise standard deviation of temperature rise value calculating the temperature rise of busbar, and then make the conforming evaluation of busbar temperature rise more accurate.
According to the described one group of busbar to be measured of temperature rise standard deviation judgement, the consistance of temperature rise comprises during by described the first electric current: by the temperature rise standard deviation and preset standard is poor compares, when the temperature rise standard deviation is less than preset standard when poor, one group of tested busbar temperature rise high conformity; When the value of temperature rise standard deviation is greater than preset standard when poor, one group of tested busbar temperature rise consistance is poor, and preset standard is poor is the standard deviation decision content of setting according to actual needs.Because can reflecting a plurality of measurement data, standard deviation departs from the degree of measurement data mean value, therefore the temperature rise standard deviation of one group of busbar can reflect that the temperature rise of this group busbar departs from the degree of average temperature rising, can detect the temperature rise standard deviation of the busbar that obtains meeting request for utilization according to test of many times, and using that this is poor as preset standard, if it is poor that the temperature rise standard deviation of one group of busbar to be measured is less than preset standard, the degree that shows one group of tested busbar temperature rise whole departure average temperature rising is less, temperature rise value difference is less, be conducive to avoid when battery is used in groups, thereby because differing greatly, busbar temperature causes the too high destruction of local temperature battery, if it is poor that the value of the temperature rise standard deviation of one group of busbar to be measured is greater than preset standard, the degree that shows one group of tested busbar temperature rise whole departure average temperature rising is larger, temperature rise value differs greatly, when battery is used in groups, easily produce local temperature too high, thereby destruction battery.Thus, can facilitate, select to meet accurately the busbar of request for utilization.
Preset standard is poor multiple choices, can be preferably 0.02 poor as preset standard, by busbar being carried out to lot of experiments and statistical analysis can obtain, the temperature rise standard deviation reaches the request for utilization that can meet busbar at 0.02 o'clock, therefore, it is 0.02 poor as preset standard to select, and for judging busbar temperature rise consistance, provides criterion.
Each busbar in one group of busbar to be measured is all applied to the first electric current to be comprised: respectively each busbar in one group of busbar to be measured is applied respectively the first electric current or, by after one group of busbar series connection to be measured, one group of busbar to be measured applied to described the first electric current simultaneously.Respectively each busbar in one group of busbar to be measured is applied respectively to the first electric current, can make to equate by the electric current of each busbar, while avoiding electric current to flow through a plurality of busbar, the energy loss of generation, and can prevent from busbar is accessed to same circuit simultaneously the time, the temperature between each busbar influences each other; Also can be by the same circuit of each busbar series connection access, provide same current by same power supply for each busbar, during by the known busbar series connection of the characteristic of series circuit, electric current by each busbar equates, thereby can only with a power supply, a circuit, just can apply the first electric current to one group of busbar to be measured simultaneously, simplify the step that each busbar in one group of busbar to be measured is all applied to the first electric current.
In order to promote the accuracy to the conforming evaluation of busbar temperature rise, during by described one group of busbar series connection to be measured, each busbar in one group of busbar to be measured is spaced from each other a distance.Due to each busbar when the electric current, temperature all can be freeed variation, between each busbar, temperature can influence each other, therefore, need each busbar in one group of busbar to be measured is spaced from each other a distance, thus, can reduce the impact of the temperature of each busbar on the temperature of other busbars, thereby improve the accuracy to the conforming evaluation of busbar temperature rise.
Accurate in order to make the conforming evaluation of busbar temperature rise, at each busbar, by the process of the first electric current, when temperature variation tends to be steady, continue within the predetermined time each busbar is all applied to described the first electric current, when reaching predetermined time, read the equilibrium temperature of described each busbar.Because each busbar temperature by electric current the time can rise gradually, when temperature variation tends towards stability, continuation applies the first electric current and continues for some time each busbar, after the temperature of guaranteeing each busbar reaches equilibrium temperature, significant change no longer occurs, now read equilibrium temperature, whole temperature uphill process that could reflect busbar, thus, can make the temperature rise value calculated and the temperature rise standard deviation of being calculated by temperature rise value more accurate, thus make one group of tested conforming evaluation of busbar temperature rise more accurate.
Interference for fear of ambient temperature to the busbar temperature rise, when each busbar in one group of busbar to be measured all applies the first electric current, keep the residing environment temperature of each busbar in one group of busbar to be measured constant.The impact of the electric current that passed through by external environment and busbar self due to the temperature of busbar, in order to estimate accurately one group of busbar to be measured temperature rise consistance by the first electric current the time, need to get rid of the impact of environment temperature on busbar temperature, it is constant that environment temperature keeps, can prevent from because ambient temperature changes, busbar temperature being changed, thus, can avoid the interference of ambient temperature to the busbar temperature rise, it is more accurate to make the conforming evaluation of busbar temperature rise.

It is 155A in measuring current that the embodiment of the present invention also provides another group busbar, embodiment when environment temperature is 30 ℃, and when the electric current by each busbar is 155A, when environment temperature is 30 ℃, the temperature variations of busbar 21 is as shown in Figure 9; The temperature variations of busbar 22 as shown in figure 10; The temperature variations of busbar 23 as shown in figure 11; The temperature variations of busbar 24 as shown in figure 12; The temperature variations of busbar 25 as shown in figure 13, the temperature rise value of each busbar as shown in figure 14, utilize the standard deviation formula to calculate, the temperature rise standard deviation of this group busbar is 0.02, if selecting preset standard poor is 0.02, to equal preset standard poor for the temperature rise standard deviation of this group busbar, can judge that thus this model busbar temperature rise has consistance.
