A friend is working on a solar-battery tender for auto, marine and maybe motorcycle applications. Virtually every candidate charge controller involves a switching power supply which will inject some ripple into the system. Is there any reason to be concerned about this?
I tend to think it's no concern since the battery itself acts like a big filter and automotive systems have to be designed for noise immunity anyway. A battery charger is 100% ripple, but of course at low frequency.
Does there need to be a specification on the frequency or magnitude of ripple that is applied to the battery?
