I'd like to use a boost converter as the primary power supply for a lipo charger. Disregarding the BMS, which will be a separate component, how does a step-up boost converter behave when used as a battery charger?
I'm looking at something like this boost converter, and my system is 28V input, up to 50.4V output (12s lipo). A p-channel switching circuit would switch source (output of converter) to load (battery pack)
A Lipo battery should be charged first at constant current and increasing voltage, followed by constant voltage and decreasing current.
Does something like the above boost converter:
- Output maximum current at varied increasing voltage, then decrease current once maximum voltage is reached?
- Output maximum current + voltage at all times?
- Do something else entirely?
Would a single converter be appropriate, or would the system require one configured for constant current, then switch to another configured for constant voltage?
