I picked up on the second part of *your* reply and showed that you
were wrong. In fact there are plenty of fluids which require changing
in electric cars, including the fluids in the batteries. In fact you
did not know that and are now trying to wriggle out of discussing a
topic which *you* introduced.

what fluids might those be?

lithium ion batteries do not have fluids to change.

the 12v battery does have fluids, otherwise known as water, which
doesn't require changing and is almost certainly a maintenance free
battery where it *can't* be changed.

if that battery needs any water at all, then something is wrong with it
and/or the vehicle's charging system. that is *not* a maintenance task,
but rather a symptom of an actual problem.

surprising as it may seem, problems do occur.

once again, you fail to understand the topic and only wish to argue.
