In the strong coupling Bose-Einstein Condensation (BEC) regime thesuperconductors have two characteristic temperatures: $T^*$- onset of fermionpairing and $T_{sc}$- onset of superconductivity, such that $T_{sc}<T^*$. Inthe present article, we consider time dependent Ginzburg-Landau theory ofsuperconductors with slab geometry and show that applied electric field, in thetemperature interval $(T_{sc},T^*)$, Bose condenses the Cooper pairs therebyincreasing the superconductor critical temperature $T^E_{sc}>T_{sc}$. Importantconsequence is the fact that arbitrary temperature within the interval($T_{sc},T^*$) is a critical temperature of superconductor transition if anappropriate electric field is applied. This means that if we set thetemperature of the system within the above mentioned interval and increase theapplied electric field the system undergoes an electric field inducedtransition to superconductor.  We also show the existence of critical value of the applied electric field atwhich $T^*=T^E_{sc}$. This means that although the system is in BEC regime,  away from the BCS one, we can apply an electric field that moves the systemto a state with $T^E_{sc}=T^*$, characteristic of BCS regime. The resultsindicate that applied electric field experiments are a suitable tool toidentify the BEC regime of the superconductors. The experiment can determine$T^*$ as a temperature below which the electric field Bose condenses the Cooperpairs, while above it the electrons screen the field and it cannot penetrate.
