Abstract

In one embodiment, a system for deploying batteries, for example in an electric vehicle, includes a battery belt for mechanically linking multiple batteries together, a conduit having one or more operational zones each with an output, the operational zones each establishing an electrical connection between the output and batteries in the operational zone, and an actuator for selectively moving batteries into and out of the operational zones. Resting zones may also be provided. The batteries can be connected in series or in parallel and can be individually removed and replaced by an exchanger.

Claims

a battery belt for mechanically linking multiple batteries together;

a conduit having an operational zone with an output, the operational zone establishing an electrical connection between the output and batteries in the operational zone; and

an actuator for selectively moving batteries into and out of the operational zone,

wherein the conduit comprises a plurality of conduit links serially connected together electrically by severable electrodes.

2. The system of claim 1, wherein the battery belt links the batteries together in a linear arrangement, and the conduit extends in a linear direction and constrains movement of the battery belt therein to the linear direction.

3. The system of claim 1, wherein the conduit includes a resting zone, the actuator selectively moving batteries into and out of the resting zone.

4. The system of claim 1, wherein the conduit includes an additional operational zone, the actuator selectively moving batteries into and out of the additional operational zone.

6. The system of claim 1, further including a controller for activating the actuator.

7. The system of claim 6, wherein the controller activates the actuator based on input received from one or more of an electric vehicle, a battery charger, and a sensor of parameters associated with one or more of the batteries, said parameters selected from one or more of temperature, voltage, current, and power.

8. A system for deploying batteries comprising:

a battery belt for mechanically linking multiple batteries together;

a conduit having an operational zone with an output, the operational zone establishing an electrical connection between the output and batteries in the operational zone;

an actuator for selectively moving batteries into and out of the operational zone; and

an exchanger for removing one or more batteries from the battery belt,

wherein the exchanger is configured to replace at least one removed battery with a replacement battery.

9. The system of claim 8, wherein removal of a battery severs the battery belt.

10. An electric vehicle comprising:

a drive system;

a battery belt for mechanically linking multiple batteries together;

a first conduit having a first operational zone with first output coupled to the drive system, the first operational zone establishing an electrical connection between the first output and batteries in the first operational zone; and

an actuator for selectively moving batteries into and out of the first operational zone.
