Read this: Nuclear Battery This is called a 'microreactor'. Imagine it scaled down a few hundred more percent to power a vehicle. Or even better, sized to power homes. Imagine no need for power lines to homes.
Then, there is this from nuclear waste: Nuclear Waste Battery This may be more feasible in the near future.
Lastly, an EV that burns gas/diesel/propane or whatever whose ONLY job is to run an alternator to charge batteries. That is feasible now.
But as can be seen, these are all energy sources, which is the only way a battery can 'recharge itself'. It can't recharge from energy it has already used.
