Abstract

The utility model relates to an accumulator working state display which is composed of a photoelectric display device. The device is formed by that a color changing luminous diode and working circuit elements thereof are connected and assembled together. The display respectively displays different working conditions of the accumulator by means of different light colors sent out by the color changing luminous diode in order to guarantee the normal run of the equipment.

Description

Displayer for working state of storage battery

The utility model relates to a kind of demonstration of charge and discharge duty of accumulator, particularly utilizes variable color luminotron (LED) to send the different photochromic display device of representing the various duties of accumulator and system thereof respectively.

Equipment such as every various automobiles of being furnished with accumulator, steamer, tractor, internal combustion engine also all are furnished with the display device that whether accumulator is in charge and discharge.Up to the present this kind equipment overwhelming majority all adopts reometer to show, some has begun to use voltage table instead or charging indicator light shows.

The complex structure of this class instrument, manufacture difficulty is big, low precision or cost height, and inconvenience is installed and takies certain instrument panel face, and the shown numerical value of instrument there is no great practical value to the operation of equipment.

Represent according to using charging indicator light instead on the now a lot of vehicles of practice situation whether accumulator is in the charge and discharge state, though showing than instrument, this device improves to some extent, but show more single, the demonstration of adopting at present can't make the operator satisfied, and various circuits are numerous, can't unify, bring difficulty to maintenance.

The purpose of this utility model provides a kind of easy to install, show clear and definite eye-catching, make easily, the display device of cost is low, the life-span is long, effective battery-operated state.

The purpose of this utility model is to realize like this, it is to utilize the difference of accumulator magnitude of voltage when various duty to change that the difference by current conditions produces the different photochromic various working conditions of representing accumulator respectively in the variable color luminotron (LED), so that make the operator recognize that in time the real work situation of accumulator guarantees the normal operation of equipment.

The utility model is because only need a variable color luminotron (LED) and simple circuit composition, so have the characteristics easy, with low cost of making.Though this display has only a variable color luminotron (LED) but can replace several groundwork state status of accumulator and system thereof, substantially equipment and operator's needs have been satisfied, simplified circuit instrument panel face, and install and use all very convenient, can extensively apply on any relevant various new used equipments few, the instant effect of recondition expense.

The concrete structure of utility model is drawn by following accompanying drawing:

Fig. 1-the 3rd is according to the electrical principle synoptic diagram of battery-operated status displays under several duty situations that the utility model proposes.

Among the figure :+dc power anode;-dc power cathode;

CW1, CW2 voltage stabilizing diode

R resistance; Electric current in I1, the I2 circuit;

LED variable color luminotron, wherein C is the luminotron public pole, and G is a luminotron green emitting part, and R1 is a luminotron emitting red light part.

Individual embodiment of the present utility model is described here in conjunction with the accompanying drawings.

Fig. 1 is that circuit accumulator after normal the connection is in the discharge duty, makes display lighting pipe green emitting partly send green glow, represents that this circuit on battery tension is normal.

Fig. 2 be after circuit is connected in the circuit voltage be higher than battery tension and make that luminotron is green to be sent green glow and ruddiness simultaneously with the emitting red light part and be mixed into sodium yellow and represent that accumulator is in the state of being recharged.

Fig. 3 is that the voltage in the circuit is higher than specified charging voltage and makes the red brightness of luminotron emitting red light part bias toward red light greater than green its mixing of brightness photochromic later on and be reddish orange, voltage is in malfunction above the charge capacity definite value in the indication circuit, to remind the operator, need maintenance in order to avoid damage equipment.

Working as this display in addition is under Fig. 1 energising situation, if accumulator heavy service under serious power shortage situation causes that battery tension descends significantly, the green light that display was originally sent is extinguished, and the existing fault of accumulator needs maintenance in the indication circuit, can in time remind the operator to arouse attention.

Characteristics of the present utility model are in sum: send different photochromic and bright variations of putting out by a color-changing light-emitting pipe, reflected that basically groundwork state in battery and the system is to guarantee the equipment normal operation.
