1. In a vehicle having an engine actuated by a starter motor, a circuit for providing capacitor-assisted electrical energization of the starter motor, comprising:

  • the starter motor;

    a battery communicated to the starter motor;

    a capacitor pack comprised of a multiplicity of capacitors;

    the pack communicated to the battery and to the motor;

    a power control switch connected in series between the pack and the motor;

    regulator means for allowing current from the battery to flow to the pack at no more than a selected limited rate, the regulator means connected between the battery and the pack in parallel with the power control switch;

    a regulator switch between the regulator means and the pack; and

    control means for selectively opening and closing the power control switch and the regulator switch in response to a predetermined voltage level of the pack.
