Hi all,
I'm working on a circuit that automatically discharges batteries I have up to a certain voltage - let's call it Vcut. I've opted for biasing a Mosfet with a zener diode. That Mosfet in turn regulates the current of a Relay, switching between a load resistor and a "job done" LED. I've attached a rough schematic and the .txt file generated by Falstad Circuit Simulator.
I have three questions:
- I'm still super new to electronics, so anybody seeing blatant mistakes, please comment.
- Second, when a battery is disconnected from the load, the voltage at the terminals gradually rises back up. In this case, that would mean the circuit would endlessly go from open to close to open to close when reaching Vcut. Any leads on how to address this in a simple way?
- Third, as simulated, it appears the relay is connected to neither poles between battery voltages 21.85V and 21.68V. Any suggestions on how I can clean this up?
Thanks.
