6 FAQs about [Battery low voltage cut-off circuit diagram]

What is a low battery cut-off and overload protection circuit?

A very simple low battery cut-off and overload protection circuit has been explained here. The figure shows a very simple circuit set up which performs the function of an overload sensor and also as an under voltage detector. In both the cases the circuit trips the relay for protecting the output under the above conditions.

How does a 12V battery low voltage disconnect circuit work?

The 12V-Battery Low Volt Disconnect Circuit uses an LM358 IC as a voltage comparator to monitor the battery voltage. When the voltage drops below a preset level, the output of the comparator goes low, which is connected to the gate of the IRFZ44 MOSFET. The MOSFET is used as a switch that cuts off the power supply to the load.

What is a low voltage disconnect (LVD) circuit?

A Low Voltage Disconnect (LVD) circuit is designed to shut off the power supply to any load before the voltage of the battery drops below a certain level. In other words, it protects the batteries from getting completely drained, which can lead to permanent damage and decrease its lifespan.

How does a low battery indicator work?

Referring to the above diagram, the low battery indicator is formed by the two NPN transistors, while the additional BC557 and the relay are used for cutting OFF the battery from the load when it reaches the lower threshold, in this state the relay connects the battery to the available charging input.

What happens if a battery voltage is too low?

When the battery voltage falls beyond a certain low voltage threshold, the base current of T2 becomes sufficiently low such that it's no longer able to hold the relay into conduction and switches it OFF and also the load. The"LOAD" terminals in the above diagram is supposed to be connected with the inverter +/- supply terminals.

Can a low battery cutoff be used with a rechargeable battery?

This circuit can be used with batteries of all voltages and types like lithium-ion, lead-acid, etc. It can also be used with any voltage battery made with a separate 1.2V or 3,6V rechargeable cell. In this circuit, we are making an Adjustable Low Battery Cutoff For All Rechargeable Batteries.
