This circuit is meant for a homemade Series Hybrid vehicle.
One 38-voltage source, represents a battery.
The other 38-voltage source, represents the rectified & smoothed output, of a generator.
The Lamp represents the controller & motor.
Under normal conditions. The 38v generator is in parallel with the 36v SLA battery, to charge it to 38 volts.
But when I flip a switch, the generator will be in series with the battery, to give me more top speed & acceleration, when I need it.
And when the battery gets too low, I can switch back to charging mode. And hopefully be able to switch back and forth between charging & power modes, while the Hybrid system is on, and under load.
Maybe inductors & diodes in places, to smooth those transitions out?
My problem is.
If any of those relays fail to switch, at the exact same time as the others, that could be a disaster. Or. If I put fuses or circuit breakers in the right places, it will be a random annoyance, if I can't access the power mode, or worse, the Hybrid vehicle just stops.
Is there a relay, that can handle 80v & 40A, and has 3 Single Pole Double Throw switches, with one reliable moving part?
I'm learning Electrical Engineering on my own. And I'm building a performance Series Hybrid.
This schematic is for a prototype.
(Edit) I have found 3-phase SPDT Solid State Relays. But so far, the ones I've found for DCvolts, have rated voltages too low, but amazing Amp ratings. And the higher voltage ones I'm finding, are for AC.
Other then that. Are there any other problems with my schematic?
