Abstract
The utility model discloses a constant flow discharging load testing instrument of a storage battery. A testing loop with continuous discharge is formed by property of unidirectional conduction of a diode, and storage batteries for requiring test are connected in parallel on each diode, thereby being capable of testing the storage batteries at the same time. The storage batteries which are required to switch off are taken down from the loop when the storage batteries is close to final voltage of the discharge, because a series loop of the diode is not switched off, the diode has unidirectional conductivity, thereby not causing the discharge loop of the other storage batteries to switch off and achieving the aim of the continuous discharge test to improve test efficiency of the constant flow discharging load testing instrument of the storage battery and guaranty test results with higher accuracy based on the continuous test with small error.
Description
Technical field
The utility model relates to a kind of accumulator constant-current discharge load testing instrument.
Background technology
Accumulator constant-current discharge load testing instrument carries out constant-current discharge and then must be by calculating accumulator capacity to the accumulator that is inserted, because accumulator constant-current discharge load testing instrument has only a test port, so correct using method is once can only be to a measuring battery, but, often will be connected on the accumulator constant-current discharge load testing instrument after several accumulator series connection in order to improve detection efficiency.When the series connection accumulator is in discharge condition, battery tension can reduce gradually, and because there is inconsistent situation in accumulator, the accumulator that has can reach the final voltage that allows discharge in the short period, if untimely with its disconnection, overdischarge will appear in accumulator, can cause damage to accumulator, influence accumulator property, even produce short circuit, faults such as heating.When reaching the final voltage of discharge, accumulator should in time it be broken from the loop, because all accumulators are to be connected in series, disconnecting wherein, any one accumulator can make that all test loop is in off state, the test duration that remains accumulator like this is discontinuous, is interrupted test and causes test result to have bigger error.So such accumulator constant-current discharge load testing instrument detection efficiency is low, a plurality of while test errors are big.
The utility model content
The technical problems to be solved in the utility model provides a kind of accumulator constant-current discharge load testing instrument, can accurately measure a plurality of accumulators simultaneously, and any accumulator detects finishes the connection status that can not change other accumulators after disconnecting from the loop, guarantees that each accumulator can follow-on test.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this accumulator constant-current discharge load testing instrument is provided with positive terminal and the negative terminals that is used to test, be connected with uninterrupted discharge connector between described positive terminal and the negative terminals, described uninterrupted discharge connector comprises at least two diode in series, the negative pole of described uninterrupted discharge connector is connected with negative terminals, the positive pole of described uninterrupted discharge connector is connected with positive terminal, be provided with the negative pole interface that is used to connect battery terminal negative at the positive pole place of diode, be provided with the anode interface that is used to connect battery positive voltage at the negative pole place of diode.
The utility model adopts technique scheme, utilize the characteristic of the unidirectional conducting of diode to form a uninterrupted test loop that discharges, the accumulator of required test in parallel on each diode, so just can test these accumulators simultaneously, from the loop, take off on the accumulator that when accumulator reaches the final voltage of discharge, only needs to need to disconnect, because the diode series loop does not disconnect, has unilateral conduction, can not cause other battery discharging loop to disconnect, reach the purpose of uninterrupted discharge test.Thereby improved the testing efficiency of accumulator constant-current discharge load testing instrument, and follow-on test guaranteed the test result of degree of precision, error is little.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the schematic diagram of a kind of accumulator constant-current discharge of the utility model load testing instrument.
Embodiment
This accumulator constant-current discharge load testing instrument has comprised tester 1 and has been connected the positive terminal 2 of tester 1 and the uninterrupted discharge connector between the negative terminals 3.Should at least two diodes that are cascaded 4 have been comprised by uninterrupted discharge connector, as shown in Figure 1, three diode 4 series connection backs are inserted on the accumulator constant-current discharge load testing instrument 1, the positive pole of the uninterrupted discharge connector that is composed in series by diode 4 is connected this tester 1 and is provided with the positive terminal 2 that is used to test, and the negative pole of the connector that uninterruptedly discharges is connected this tester 1 and is provided with the negative terminals 3 that is used to test.The positive pole place of each diode 4 is provided with the negative pole interface 5 that is used to connect battery terminal negative, is provided with the anode interface 6 that is used to connect battery positive voltage at the negative pole place of diode 4.During test, the negative pole interface 5 on all diodes 4 is connected on the negative pole of accumulator, anode interface 6 is connected the positive pole of accumulator.Each accumulator of energising back is cascaded, because the unidirectional conduction of diode 4 makes electric current not by diode 4.From the loop, take off on the accumulator that when accumulator reaches the final voltage of discharge, only needs to need to disconnect, this moment, electric current was just from passing through with this accumulator diode connected in parallel 4 that is disconnected, other connection status at the accumulator of surveying are unaffected, still are communicated with tester 1.So the utility model can be tested three accumulators simultaneously, can certainly test more accumulators simultaneously, only need the diode 4 of required number in the series connection of uninterrupted discharge connector, not only improve testing efficiency, also obtain the very little test result of error, guaranteed testing precision.
