Battery Cut Out Relay

The inverter puts out up to 100 amps to charge my batteries.

Battery cut out relay.

Further reducing relay coil power. The circuit responds cutting off when the voltage of the batteries goes below 22v and rearms at around 23v actually the batteries serial voltage is around 24v as i have 3 power diodes in series with the input which reduce the measured voltage at the zener in 2v approx. The electromagnet consists of 2 coils shunt and the series. As an experiment to turn on a genset to turn on a generator and the generator and inverter takes care of charging my battery bank.

A simple cut out relay is as shown in the figure. A cutoff switch is installed on or near the battery and is used primarily to prevent battery charge depletion and for long term storage. Adding two common components reduces the relay coil voltage and current to 70. A fused switch will maintain current to your alarm on board computer central locking system and stereo but still prevent your car from starting the current generated when attempting to start the vehicle will blow the fuse and shut down all electrical.

Simply flip the battery disconnect switch and the flow of current from your battery will be shut off. A battery disconnect switch is also a great tool for cars that you only take out on special occasions. When the generator is producing sufficient voltage so that the field due to both the current and voltage coils support each other the electromagnet pulls down the armature the contacts are closed and the generator battery circuit is. To further reduce the relay coil current i employed a relay economy technique described in a previous post.

Therefore the battery will cut off when the battery voltage of each li ion battery is at 4 2 v approximately. A battery disconnect switch makes this easy by allowing you to disconnect the battery without any tools.

Also when the relay drops out the control circuit current drops to about 4ma thus minimizing battery drain.
