Hi, We are building a robot that moves on fixed rails. The robot will have lots of electronics, motors etc. on board. There will be continuous DC (24V) voltage available through the rail system, but it won't deliver more than couple of amps.
Our plan is to put a 24V battery in the robot to provide extra power. What would be a good way to combine the two power sources? I would like the system to:
1) Provide all the power from the rail when consumption is less than 2 amps and at the same time charge the battery.
2) When consumption is more than 2 amps, provide 2 amps from the rail and the rest from the battery.
3) Use only the battery when the rail power is not present.
Are there commercial systems for this kind of setup? I need good advise on how to approach this problem. Lipo batteries would be nice, but I can live with sealed lead acid batteries too. I can also design the system for higher rail voltages (up to 50V). The battery should be ~24V.
