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.
What is a low voltage cutoff circuit?
A low voltage cutoff circuit is an electronic circuit that monitors the voltage of a battery and disconnects the load when the voltage drops below a predetermined threshold. This prevents the battery from being over-discharged, which can lead to reduced performance, shorter lifespan, and even permanent damage.
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.
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.
How do I Disconnect a battery from a power supply?
Disconnect the battery from the circuit and connect an adjustable power supply instead. Set this power supply at the voltage on which you want to disconnect the battery from the load. If you are using a 12V battery then set 11.9V in an adjustable power supply and adjust the 100K pot/trip point until the LED turns off.
How does low battery sensing work?
The low battery sensing is handled by R3 and P1 which forms a potential divider to set the base voltage of the relay driver transistor (T2). When the battery voltage drops below a set threshold the voltage at the base of T2 falls below V be (0.6V–0.7V) turning OFF the relay and disconnecting the load. Formula for Threshold Voltage:
