Abstract

The Self-Sustaining Electric Engine Enhancement (SSEEE) specification modifies the process by which electric car engines consume and replenish electric power and dramatically extends the distance a car can travel before the need for pit stops to recharge the energy source, i.e., batteries, fuel cells, etc. It introduces a hot swappable configuration of battery/fuel cells to allow for quick exchange for a charged fuel source. It changes the process by which batteries or any fuel source is utilized. It introduces an intelligent device that controls access to batteries for both consumption and replenishment. It adds a charging device to the electric vehicle for a self-sustained power source. It eliminates the need in hybrid engines to have the entire engine be fueled by gas or biofuel—only the Charger(s) will be powered by gas/biofuel. Finally, it adds high availability and scalability enhancements to the existing electric car power processes to allow for continuous operations of the vehicle in the case of some component failures. It'"'"'s a marriage of Information Technology and Electric Car paradigms.

Claims

1. Existing electric car functionality has three major components that power the electric vehicle. They are an Array of Batteries/Fuel Cells, a Controller and the Electric Engine. The Controller receives power from the batteries and uses that power to power the electric engine. This specification adds two new major components that work to power an electric vehicle. They are a computerized Access Manager and a Charger. The Access Manager grants access to the batteries/fuel cells, in a circular fashion, to the Controller for power consumption and to the new Charger device for power replenishment. The Controller no longer has direct access to the batteries as a fuel source.

2. As stated in claim 1, the batteries will be accessed in a circular fashion. Each battery is logically assigned a numeric value based on the port on the Access Manager to which it is attached. Meaning, if an Access Manager has six ports, with a battery attached to each port, the batteries would be numbered 1 through 6. The Access Manager grants access to individual batteries, in a circular fashion, starting with battery number 1, on through to battery number 6, and then starring again at battery number 1, providing continuous cycling through the batteries. The Access Manager can have more or less than 6 ports. In this case, 6 ports were selected to show the spirit and functionality of this new power processing and replenishment process.

3. As stated in claim 1, the new Access Manager computing device grants both the Controller and new Charger access to individual batteries in a circular fashion. The Assess Manager grants the Controller access to each battery/fuel cell in a circular fashion. After the Controller consumes a battery'"'"'s power down to a predetermined threshold, the Access Manager switches the Controller'"'"'s access to the next battery/fuel cell. The Access Manager then invokes the Charger to recharge the battery that was drained by the Controller. This process is continued in a circular fashion, allowing for extended driving distances of an electric vehicle. Only the Charger(s) will be powered by gas/biofuel.

4. Each element in the array of batteries can be one or more batteries/fuel cells. For example, in claim 2, there are 6 ports on the Access Manager, with each port attached to a battery/fuel cell that is part of the Array of Batteries. Each of those elements can also be an array of batteries. Additionally, each element is hot swappable, meaning that each element can be individually pulled out and replaced by a fully charged element.

5. Further enhancements, designed to implement component redundancy, is to install redundant copies of both the new Access Manager computing device and new Charger device in the electric vehicle. The first Access Manager device serves as the primary device utilized by the vehicle. The second Access Manager device serves in a failover capacity when the primary device fails. Each Access Manager has built in functionality to test each other and to send alerts if either of the devices fail. The multiple Charger devices will be used in an active/active manner, meaning multiple Chargers can simultaneously charge multiple batteries in the event a single Charger cannot keep pace with battery consumption by the Controller.

6. As stated in claim 5, in the advanced configuration, a pair of Access Managers can be installed. If the primary Access Manager fails, the secondary Access Manager will engage and keep the car operational until the primary Access Manager is repaired or replaced. This is an optionally add on configuration.

7. As stated in claim 5, in the advanced configuration, a pair of Chargers can be installed. If the first Charger falls behind on charging batteries (it'"'"'s working at a rate slower than the Controller is draining batteries) then the Access Manager will engage the second Charger to assist with charging batteries. Additionally, if either of the Chargers fails, the other will continue to supply charging functionality until the failed charger is repaired or replaced. This design could be extended to comprise more than two chargers. This is also an optionally add on configuration.
