In which parts of antenna the charges acclerate?

Parts with r-f-current flow, the greatest radiation occurring from
locations along the radiator where current is greatest.

Your words: "Only the change in current and charge, over time, produces EM
radiation."
At oscillations the current start from zero, accelerate to max speed and
deccelerate to zero.
At the max speed no acceleration at all.

Current flow is near zero at the ends of any unloaded dipole, and at
the top of any unloaded vertical monopole (even those in directional
arrays).

At the ends are the max accelerations and the max radiation.
