SYSTEMS AND METHODS FOR POWERING ELECTRIC VEHICLES USING A SINGLE OR MULTIPLE POWER CELLS
First Claim
1. A power delivery system to deliver electric power to an electric vehicle prime mover, the system comprising:
- a prime mover;
a circuit that electrically couples the prime mover to one or more electrical energy storage devices; and
at least one circuit element having a number of operational states, including at least;
a first state in which an electric vehicle is placed in a first operating mode where energy is supplied by a single electrical energy storage device to the electric vehicle prime mover; and
a second state in which an electric vehicle is placed in a second operating mode where energy is supplied by a plurality of electrical energy storage devices to the electric vehicle prime mover;
wherein the first state does not preclude a subsequent transition by the at least one circuit element to the second state; and
wherein the second state does preclude a subsequent transition by the at least one circuit element to the first state.

Abstract
Electric vehicles such as scooters can have a first operating mode in which energy is supplied by a single electrical energy storage device and a second operating mode in which energy is supplied by multiple electrical energy storage devices. A circuit element can be included in the circuit connecting the electrical energy storage devices to a prime mover such as a traction motor. The circuit element has a first, electrically conductive, state that couples only the single electrical energy storage device to a traction motor and a second, electrically non-conductive, state that couples the multiple electrical energy storage devices to the prime mover. The transition of the circuit element from the first state to the second state can occur by irreversibly fracturing the circuit element upon installation of multiple electrical energy storage devices or by a controller transitioning the circuit element from the first state to the second state.

10. A power delivery method to deliver energy to a vehicular prime mover, the method comprising:
-
delivering in a first operating mode, energy from a single electrical energy storage device to a vehicular prime mover via a circuit containing at least one circuit element in a first state; transitioning the at least one circuit element from the first state to a second state, and transitioning to a second operating mode, responsive to the electrical coupling of a plurality of electrical energy storage devices to the prime mover; and precluding a subsequent transition of the at least one circuit element from the second state to the first state after the at least one circuit element has transitioned to the second state. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
