Abstract
The utility model relates to a detecting device for a lead-acid battery, which comprises a three-terminal voltage stabilizer, a dual comparator, a potentiometer and a light emitting diode. A pregnant solution type lead-acid battery and a barren solution type lead-acid battery both can be detected at any time by the utility model, and power consumption is less. The disadvantages that only a simple lattice can be detected and detection is insensitive when an electric eye is used by the pregnant solution type lead-acid battery are avoided. The disadvantage of the barren solution type lead-acid battery that a full group of storage battery is discarded because a problem can not be discovered in time by using a multimeter for periodically detecting is also avoided.
Description
The utility model relates to a kind of pick-up unit of lead-acid accumulator.
At present the lead-acid accumulator that uses mainly is divided into two kinds of pregnant solution type and lean solution formulas, pregnant solution type lead acid accumulator is loaded onto electric eye usually and is detected its running status, its weak point is to detect single lattice situation, all the other lattice can not surveyed, and insensitive, can not detect at any time, and lean solution formula lead-acid accumulator generally is many series connection uses, need regularly detect the state-of-charge of every battery with digital multimeter, its primal problem also is to detect at any time.One Battery pack tends to thermal runaway occur owing to some battery power shortages cause whole Battery pack cisco unity malfunction, and whole Battery pack may be scrapped in very short time, and it is very necessary therefore lead-acid accumulator being detected at any time.
The purpose of this utility model is exactly the deficiency that overcomes above-mentioned prior art, and a kind of lead-acid accumulator pick-up unit that can detect at any time lead-acid accumulator is provided.
The utility model is to adopt following measure to realize: this device includes three terminal regulator, dual comparator, potentiometer and light emitting diode.Voltage stabilizer pin 2 connects the test lead negative terminal, and the test lead anode connects voltage stabilizer pin 1 by a light emitting diode, and voltage stabilizer pin 3 connects dual comparator pin 2.The test lead anode joins by potentiometer dividing potential drop and dual comparator pin 3, and dual comparator pin 1 joins by a light emitting diode and test lead anode, and dual comparator pin 4,5 connects test lead negative terminal, anode respectively.
This device before use, need to adjust according to the given ultimate value Vcc of tested power supply earlier, when the test lead of this device is placed this ultimate value Vcc, make dual comparator pin 1 place sending and receiving optical diode be in the light and shade critical conditions by adjusting the potentiometer value, promptly take it is to adjust to finish as, then potentiometer is adjusted knob and fix, stand-by.
The utility model all can detect at any time to pregnant solution type or lean solution formula lead-acid accumulator, during use the utility model test lead directly is connected on the positive and negative the two poles of the earth of accumulator, at first be that voltage stabilizer pin 1 place sending and receiving optical diode is bright, illustrate that this device contacts well with tested battery, is in normal operating conditions.Bright as dual comparator pin 1 place sending and receiving optical diode, illustrate that tested supply voltage is lower than the prescribed limit value, this accumulator is in the power shortage state, needs charging in time or adjustment.Do not work as this diode, illustrate that tested power supply is in normal operating conditions.
The utility model can promptly and accurately be measured its state-of-charge to pregnant solution type lead acid accumulator, and little power consumption, has avoided the use electric eye can only survey single lattice and insensitive shortcoming, the excessive shortcoming of power consumption when also having avoided simultaneously using discharger to measure.To lean solution formula lead-acid accumulator, the utility model can be installed on for a long time on the tested power supply and monitor at any time, prevents over because of using the regular detection of the multimeter whole Battery pack that causes of can not in time pinpointing the problems to scrap.
