Abstract
The utility model relates to a battery capacity tester, which is composed of a voltmeter (4). The voltmeter (4) is serially connected with an electronic load (2); the electronic load (2) is serially connected with an electronic switch (1); an ammeter (3) is serially connected with the voltmeter (4). The utility model can quantitatively, fast, continuously and exactly test the capacity of the on-line battery.
Description
The utility model relates to the device, particularly accumulator retained storage capacity pH-value determination pH instrument that uses or safeguard secondary cell.
A kind of discharge V shape accumulator capacity meter is arranged in the prior art, ultimate principle is to measure accumulator single lattice terminal voltage when nominal load discharges, its shortcoming is only to measure the terminal voltage of various size battery with a constant load, discharge current can not be constant, thereby can only express battery " well " of poor qualityly, can use " to be charged ", the actual state-of-charge of expression battery that can not be quantitative.
The purpose of this utility model provides quantitative, quick, online, the continuous instant analyzer of accurately measuring the accumulator retained storage capacity of a kind of energy.
The purpose of this utility model is achieved in that by voltage table forms the utility model, and described voltage table is in parallel with electronic load, and this electronic load is connected with electronic switch, and reometer is connected with voltage table.
The utility model compared with prior art has following advantage:
1) but the retained storage capacity of rapid test battery, the past can finish with the work that the constant-current discharge method needs operation in 15 hours just can finish in present 15 minutes, had saved the energy consumption of charging operation simultaneously; 2) the bad single-unit in definite rapidly electric battery has ensured the harmony and the reliability of each single-unit in the electric battery, makes the driving faults rate of battery pack drop to zero; 3) can scrap evaluation to battery, avoid the wrong report of battery useless.
Fig. 1 is a test circuit block diagram of the present utility model;
The synoptic diagram that Fig. 2 the utility model connects with accumulator;
Fig. 3 is the utility model and electric battery coupled situation vertical view.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Electronic switch 1 is with electronic load 2 series connection, displayed value by 1 control discharge time of electronic switch and latch voltage table 4, reometer 3 is connected in the discharge loop, be used to monitor the discharge current of battery, discharge loop is connected on the battery 6, operate electronic switch 1, can obtain the certain loads magnitude of voltage of battery.The measurement handle 5 of instrument is crimped on the battery output yoke plate 7, press test and press electronic switch 1, battery 6 just is in big electric current constant-current discharge state, in 3-6 a certain moment between second, discharge current 0.1C to 4C, its battery 6 terminal voltages just are locked on the panel board digital voltmeter 4.
The utility model can select for use different discharge currents to measure to different accumulators, when discharge current is chosen when suitable, at a certain moment of 3-6 between second, its terminal voltage V
TWith its retained storage capacity C
BValue has definite corresponding relation, thereby measures the terminal voltage V of cell batteries
TCan measure the retained storage capacity of battery.
Battery pack on locomotive, by assembling shown in Figure 3, the a pair of pole of every battery links with the copper yoke plate, yoke plate 8 as the A battery has connected two poles, the yoke plate 10 of B battery, the yoke plate 11 of C battery, yoke plate 13 effects of D battery roughly the same, and another of battery link respectively to the pole of pole with series-connected cell, connect two pairs of poles of A, B two batteries as yoke plate 9, and yoke plate 12 has connect two pairs of poles of C, D two batteries.When measuring the retained storage capacity value of battery, Crimping Pliers is crimped on respectively on the positive and negative terminals of this battery and gets final product.When surveying the A battery, with yoke plate 8,9, when surveying B battery, with 9,10 yoke plates, and the like.
Claims (2)
1, a kind of accumulator retained storage capacity analyzer is made up of voltage table (4), and described voltage table (4) is in parallel with electronic load (2), and this electronic load (2) is connected with electronic switch (1), and reometer (3) is connected with voltage table (4).
2, analyzer according to claim 1 is characterized in that: described voltage table (4) is a digital voltmeter.
