The rate of acceleration is mostly irrelevant for the fuel consumption, unless your engine gets in a less efficient operating mode, which is not the case with electric motors. Often enough, this is not even the case with combustion engines, especially natually aspirated ones. Only if the higher acceleration also leads to overall higher speeds or additional breaking, energy is wasted. Otherwise, the energy used for accelaration is the difference of the kinetic energy at the high minus the one at the low speed.
