Do-it-yourself battery charge indicator on two LEDs- Properly maintained batteries will work well for you and share. Maintenance includes, in particular, regular monitoring of the battery voltage. The circuit shown in Figure 1 is suitable for most types of batteries. It contains a reference LED REF , which operates at a constant current of 1 mA and provides a reference light output of constant intensity, independent of battery voltage.
This constancy is provided by a resistor R1 connected in series with the LED. Therefore, even if the voltage of a fully charged battery drops to a full discharge, the current through it will change by only 10%. Thus, we can assume that the radiation intensity remains constant in the battery voltage range corresponding to the transition from the state of full charge to full discharge.
The luminous flux of the measurement LED VAR changes according to changes in the battery voltage. By placing the LEDs close to each other, you can easily compare the brightness of their glow, and thus determine the status of the battery. Use diffused lens LEDs as clear lens fixtures irritate your eyes. Provide sufficient optical isolation for the LEDs so that the light from one LED does not hit the lens of another.
Measuring LED operation
The meter LED operates at a current ranging from 10mA with a fully charged battery to less than 1mA with a fully discharged battery. A zener diode D z with a series resistor R 2 is necessary so that the current has a sharp dependence on the battery voltage. The sum of the zener voltage and the voltage drop across the LED should be slightly less than the lowest battery voltage. This voltage drops across the resistor R 2 . Changes in the battery voltage cause large changes in the current of the resistor R 2 . If the voltage is about 1V, 10mA of current flows through the LED VAR and it glows much brighter than the LED REF . If the voltage is lower than 0.1 V, the intensity of LED VAR var will be less than that of LED REF . indicating that the battery is low.
DIY battery charge indicator- immediately after the battery is charged, the voltage on it exceeds 13 V. This is safe for the circuit, since the current is limited to 10 mA. If the LEDs are bright, quickly release the S 1 1 button (to prevent damage to them (Figure 2). Although in the example in Figure 2 the charge indicator is connected to a 12-volt lead-acid battery, you can easily adapt this circuit to other battery types.Also, you can use it to monitor the voltage.
Two green LEDs induce the state when the battery charge exceeds 60%. A set of red LEDs indicates that the battery has fallen below 20%. The LED REFG and LED REFR are connected through resistors R 1 and R 2 with a resistance of 10 kOhm. Consistent measuring LEDs, the brightness of which changes, include zener diodes and resistors R 3 and R 4 with a resistance of 100 ohms. Diodes D 1 , D 2 and D 3 set the required clamping voltage. The dependence of the brightness of the LEDs on the state of the battery is shown in Table 1.
The following expression can be used to calculate the intensity of the green measurement LED:
V BATT = 10 G x 100 + V D1 + V D2 + V LEDG + V DZ1
V BATT =10 3 x 100+0.6+0.6+1.85+9.1=1225V.
The voltage drop on the LEDs used at a forward current of 1 mA is 1.85 V. If the characteristics of the LEDs differ, the resistances of the resistors must be recalculated. At this voltage, the LEDs glow the same, which corresponds to a battery charge of 60%. A description of lead-acid batteries can be found at. The following expression can be used to calculate the light intensity of the red measuring LED:
V BATT = I R x IOO + V D3 + V LEDR + V ZD2
At 1 mA green LED current
V BATT \u003d 10 -3 x 100 +0.6 + 1.85 + 9.1 \u003d 11.65 V.
Since both red LEDs glow the same at this voltage, it means that the battery is 20% charged. The LED VARG varg is off. Figure 3 shows that both measurement LEDs are brighter than the reference LEDs, indicating that the battery is 100% charged.
Not all cars have an indicator that displays the battery charge level. The motorist must independently monitor this indicator, periodically checking it with a voltmeter, after disconnecting the battery from the machine's electrical network. However, a simple electronic device will allow you to get approximate figures without leaving the cabin.
The choice of circuit and components
Finished construction
Structurally, a self-made battery charge control indicator consists of an electronic unit, on the body of which there are three LEDs: red, blue and green. The choice of color may be different - it is important that when one of them is activated, the information received is correctly interpreted.
Due to the small size of the device, you can use an ordinary prototyping board. The optimal scheme of the device is preselected. You can find several models, but the most common and therefore workable version of the battery charge indicator is shown in the figure.
Diagram of the board and its components
Before installing the components, it is necessary to arrange them on the printed circuit board according to the diagram. Only then can you cut it to the desired size. It is important that the indicator has a minimum size. If you plan to install it in a housing, you should take into account its internal dimensions.
This circuit is designed to control the operation of a car battery with a mains voltage of 6 to 14 V. For other values of this parameter, the characteristics of the components should be changed. Their list is shown in the table.
