Description

A electrolyte level indicator of battery

The present invention detects and displays the level due to the level of a battery electrolyte for an uninterruptible power supply system (UPS), and more particularly, the level of the electrolyte contained in a battery that is centrally managed in an isolated place. The present invention relates to a battery electrolyte level indicator that detects and displays an LED light.

The battery supplies the charged current by discharging and discharges until the internal voltage reaches the set minimum voltage as the discharge proceeds, and a voltage drop occurs inside the discharge. It is called a secondary battery or a storage battery (hereinafter, referred to as a battery) because the process of recharging again before the minimum voltage is reached and supplying current by discharging is repeated for an allowed number of times.

Dilute sulfuric acid, caustic alkali, and dissolved alkali are used as electrolytes of general lead batteries. The most practically used electrolyte is dilute sulfuric acid.

The electrolyte in the battery is colorless, odorless, high purity, and promotes internal chemistry for good current conduction between each pole plate.

It is common to use lead batteries as batteries for uninterruptible power supply, and lead batteries operate by repeating discharge and charging through reversible reaction of chemical reaction PbO2 + H2SO4 ↔ PbSO4 + 2H2O. The output is discharged and the input electricity is stored as charging.

When an electrolyte solution containing sulfuric acid (H2SO4) is added to an electrode plate made of lead dioxide (PbO2) in a battery, a chemical effect of converting lead sulfate (PbSO4) and water (H2O) is used. When changed to water (H 2 O) is released electricity, on the contrary to repeat the action of charging when substituted.

That is, the charging and discharging of the lead battery is performed by chemical reaction between the active material of the electrode plate and the electrolyte solution (sulfuric acid solution), and during discharge, the active material of the electrode plate is sulfated by reacting with sulfate ions present in the electrolyte solution.

Therefore, sulfuric acid solution in the electrolyte gradually decreases during discharge, and instead, water generation gradually increases, so that the specific gravity of the electrolyte of the lead acid battery decreases in proportion to the discharge amount.

Therefore, the state of the electrolyte becomes an important factor in order to generate electricity and charge reaction stably.

When the chemical reaction formula proceeds, a small amount of hydrogen gas is generated in the battery and discharged to the outside, and the charge and discharge are repeated, so that the electrolyte gradually decreases, and the level of the electrolyte gradually decreases by evaporation.

Periodic checking and replenishment of electrolyte fluctuations in lead batteries is a traditional battery and is called a dry charged battery, and is mainly used in large vehicles such as trucks and buses and uninterruptible power supplies.

When using a maintenance type battery, the level of electrolyte decreases due to charging and discharging. Therefore, the user should check the amount of electrolyte (level) periodically and replenish if necessary.

In particular, the uninterruptible power supply uses a plurality of batteries because the uninterruptible power supply is to utilize an alternative power supply when commercial power is unstable in a place where commercial power is used.

Since the uninterruptible power supply unit charges and outputs a relatively high voltage by connecting a plurality of batteries, it is generally separated and isolated into a separate place or a cabinet equipped with a lock device for safety and normal operation.

In the prior art, the electrolyte management of the battery is an optical device using a refractive index that is floating according to specific gravity, and this technique is used in the display unit of Patent Registration No. 10-0533074 (2605. 11.25.)

And the fifth electrode 115 of the probe unit 100 through the socket.

Here, each of the thials 211, 221, 231, 241, and 251 may not operate as a switching operation when the electrodes 111, 112, 113, 114, and 115 corresponding to the base terminal are not connected.

For example, when the level of the battery electrolyte is detected by the first electrode 111 of the probe unit, the detected signal is applied to the base of the first thial unit 2110 through the cable 201 connected to the terminal unit 104 and the socket. In addition, since the first titanium part 211 operates in the switched on state, the operating power source Vcc flows to the ground or negative terminal through the resistor R1 and the first LED 212.

4 is a functional configuration diagram of the electrolyte level indicator of the battery according to the second embodiment of the present invention, Figure 5 is a functional configuration diagram of the probe unit according to the second embodiment of the present invention.

Hereinafter, with reference to the accompanying FIG. 4, the configuration includes a probe unit 150 and a display control unit 260.

The configuration of the probe unit 150 will be described in detail with reference to FIG. 5.

The probe electrode unit 151 is made of an electrically conductive conductor and is fixed to the fixing unit 154 to adjust the height. If the electrolyte is at a specified level, the probe is contacted. The detected signal is applied to the display controller 260 through the communication line 156 electrically connected.

The safety tube 152 is preferably made of a synthetic resin to maintain the probe electrode 151 in a straight state and to protect from external physical shocks and to withstand chemical substances containing electrolytes.

When screwed in this way, the stepped portion 161 of the plug portion 157 is provided with a rubber ring portion 163 to maintain a closed state between the plug portion 157 and the battery inlet.

The rubber ring portion 163 is preferably made of a kind of synthetic resin having elasticity and chemical resistance.

The display control unit 260 includes a first bullet unit Q1 261, a first LED 263, a second bullet unit Q2 265, a third bullet unit Q3 267, and a second LED unit 2. 269).

A configuration of the display controller 260 will be described in detail with reference to FIG. 4.

The first thial part 261, the second thial part 265, and the third thial part 267 each include a transistor TR that performs a switching function, and the transistor includes an emitter, a base, and a collector terminal. It may be composed of elements that operate similarly, including (field effect transistor).

The base terminal of the first thirty part 261 is connected to the probe unit 150 through a communication line 156, and the collector terminal is simultaneously connected to the first LED 263 and the resistor R1 connected in series. It is connected to the power supply Vcc and supplied with driving power.

Here, the operating power source Vcc is a power source supplied from a positive terminal of the battery, and will be described in the same manner below.

The emitter terminal is connected to the ground terminal or the negative terminal of the battery.

Therefore, the operating power supply Vcc is supplied by the plus and minus terminals of the battery.

In addition, the base terminal of the second thial portion 265 is connected to the probe unit 150 through the communication line 156, the collector terminal is connected to the resistor (R2) connected in series and at the same time to the operating power supply (Vcc) It is connected to supply driving power and emitter terminal is connected to ground or minus terminal of battery.

Meanwhile, the base terminal of the third thirty part 267 is directly connected to the collector terminal of the second thial part 265, and the collector terminal is connected to the second LED 269 and the resistor R3 connected in series. At the same time, it is connected to the operating power supply (Vcc) to receive the driving power, and the emitter terminal is connected to the ground terminal or the negative terminal of the battery.

Here, the first thial part 261, the second thial part 265, and the third thial part 267 have a switching function that operates in an on state when a signal is applied to the base terminal.

Referring to the operation according to the configuration of the present invention in detail, the inlet of the battery is a hole for injecting sulfuric acid solution or distilled water and the like is sealed with a transparent window that can be opened and closed by screwing.

The stopper 157 according to the present invention is fixed to the inlet of the battery by screwing. At this time, the stopper 157 rotates left or right due to an external force applied to the polygonal flat portion 160, and thus the thread 162 is released from the screwed or fastened state with the thread formed in the inlet, and the rubber ring 163 is released. The sealed state is maintained.

The probe electrode 151 fixed to the fixing part 154 rotates left or right by an external force applied to the handle part 155, and thus the thread 153 and the through hole formed on the outer circumference of the fixing part 154. The thread 159 formed on the inner circumference of the 158 is screwed to move the probe electrode portion 151 upward or downward.

That is, the position of the probe electrode 151 is adjusted up and down by using the handle 155 to accurately detect the level value due to the level of the designed electrolyte.

The communication line 156 transmits the level value of the electrolyte level detected from the battery by the probe electrode 151 electrically connected to the first and second tials 261 and 265 of the display controller 260. Apply simultaneously.

Here, the level detection value for the electrolyte level is detected as a normal on value that does not need to be replenished and an off value that requires replenishment of the electrolyte.

For example, when the first thirty part 261 receives the on value detected by the level value of the electrolyte level from the probe part 150 through the communication line 156 to the base terminal, it is switched on. It works.

The first titanium part 261 operating in the switched-on state by the ON signal applied to the base terminal causes the operating power Vcc to be applied to the first LED 263 through the resistor R1 and is negatively connected to ground or the battery. To the terminal.

Therefore, the first LED 263 operates to emit light, and the light output by the first LED 263 is green (green), and green indicates that the level due to the level of the electrolyte is normal.

At this time, the second thial part 265 receives the on value detected as a level value by the level of the electrolyte from the probe part 150 to the base terminal, and operates in a switched-on state, through the resistor R2. Apply an applied operating power supply (Vcc) to the ground or minus terminal of the battery.

The voltage is not applied to the collector terminal of the second thial part 265, so that no voltage is applied to the base terminal of the third thial part 267 connected to the collector terminal of the second thial part 265. ) State.

Therefore, the second LED 269 connected to the collector terminal of the third thial unit 267 operating in the off state does not operate and does not emit light because the operating power is not supplied.

As another example, when the probe unit 150 detects an off state due to insufficient battery electrolyte, an off signal is applied to the base terminals of the first and second tials 261 and 265, respectively. Operate in switched off state.

The first LED 263 connected to the collector terminal of the first thirty-stage 261 operating in the switched-off state does not emit light because the operating power source Vcc is not supplied.

At this time, all the voltages of the operating power source Vcc are detected by the resistor R2 at the collector terminal of the second thial unit 265 operating in the switched off state.

Since the base terminal of the third thirty part 267 is connected to the collector terminal of the second thirty part 265, all of the voltages detected at the collector terminal of the second thirty part 265, that is, the voltage of the operating power supply Vcc It is applied to the base terminal of the third thial portion 267.
