In this work, it is shown that the energy and momentum of electromagnetic fields created by a classical charge, whose velocity varies with time, do not form four-vector. A possible explanation for this result is that the calculation of energy and momentum is performed as an integration of the densities of these quantities, \it i.e. the squares of the electromagnetic field E2 and H2 in the whole space at the hyperplane t=const. But E2 and H2, which are calculated at a fixed point in time, t, are all created at previous (retarded) instants of time. In other words, all densities E2 and H2 are independent of each other. Meanwhile, Lorentz transformations are defined as transformations between physically connected quantities.
