Background: For a university final project, my student group is investigating the possiblility of powering a motorcycle with two seperate batteries, each of a different chemistry (Lead-acid and Lithium-ion). The idea behind the design is to try and achieve a design which costs less to produce but has the same range as one that uses exclusively Li-ion. We want to power the bike with li-ion at low power demands (e.g. cruising or gentle acceleration) and then switch from the li-ion to lead-acid powered for times when a higher power is needed (harsh accelerationa and high top speeds for a short time). Initially we were hoping to simply disconnect the first power source then switch over to the second. However after speaking to a professor here he advised that the controller would register a 0A current and switch off meaning the whole system would need to be reset before it could start working again. Obviously this is not suitable for an electric vehicle.
So my question is: Is it possible to power a single motor with one power source then quickly switch to another power source (of equal voltage) without damaging any components and ideally not losing power for an extended amount of time while switching? Also we would ideally want to make sure that the unused power source is completely disconnected and not using any power when not in use.
Sorry for my inexperience and if any of the above didn't make too much sense, electronics isn't my strong suit (mechanical engineer).
I've had a read of existing questions related to mine but can't seem to find any relevant ones, if anyone has any knowledge of some that would be very helpful. Also if anyone knows of any existing work that has done something similar that would also be really useful.
