Straightforward Lead Acid Battery Charge Monitor Circuit
According to producer's information sheets, a 12V rechargeable lead-corrosive battery ought to be worked inside 10.1V and 13.8V. At the point when the battery charges higher than 13.8V it is said to be cheated, and when it releases underneath 10.1V it can be profoundly released. A solitary occasion of cheat or profound release can cut down the charge-holding limit of a battery by 15 to 20 for each penny.
It is along these lines important for all worried to screen the charge level of their batteries ceaselessly. In any case, practically speaking, a number of the battery clients can't do as such on account of non-accessibility of sensibly estimated observing hardware. The circuit thought displayed here will fill this void by giving a circuit to observing the charge level of lead-corrosive batteries persistently. The circuit has two imperative elements:
To start with, it diminishes the prerequisite of human consideration by around 85 for every penny.
Second, it is an exceptionally precise and modern technique.
Circuit Diagram:
The circuit is controlled by the battery under test, by means of a voltage controller IC. The circuit takes around 100 mA for its operation.
For aligning the upper and lower reference levels, a computerized multimeter and a variable managed control supply source are required. For adjusting the lower reference voltage, take after the means given beneath:
Set the yield of energy supply source to 10.1V.
Interface the power supply source set up of the battery.
Presently the show will demonstrate some perusing. Now fluctuate preset VR2 until the perusing on the show just changes from 1 to 0.
The higher reference voltage is adjusted comparably by setting the power supply to 13.8V and shifting preset VR1 until perusing on the show just changes from 8 to 9.
After the adjustment is finished, the circuit might be housed in a reasonable fenced in area. The cost of the considerable number of segments, including the fenced in area, would associate with Rs 200.
