First claim

What is claimed:

1. An apparatus, comprising:
a battery management module for a hybrid vehicle, the battery management module including:
a propulsion power module structured to determine a potential propulsion power for the hybrid vehicle at a particular location of a route of the hybrid vehicle at a particular time based on at least one of internal information regarding the hybrid vehicle, external static information regarding the route of the hybrid vehicle, and external dynamic information regarding one or more upcoming potential conditions along the route of the hybrid vehicle; and
a battery state of charge module structured to manage a state of charge of a battery of the hybrid vehicle at the particular location at the particular time based on the determined potential propulsion power;
wherein responsive to determining a downhill grade at the particular location, the battery state of charge module is structured to determine an amount of braking energy available during traversal of the downhill grade and discharge the battery to direct energy to at least one of a generator or an electrified accessory of the hybrid vehicle before the downhill grade to enable reception of at least a portion of the determined amount of braking energy available.

2. The apparatus of claim 1 , wherein responsive to the external static information indicating an uphill grade at the particular location and the determined potential propulsion power on the uphill grade for a target hybrid vehicle speed, the battery state of charge module is structured to facilitate a charging of the battery in advance of the uphill grade.

3. The apparatus of claim 2 , wherein the battery is charged to meet the determined potential propulsion power on the uphill grade without increasing an engine output power amount.

4. The apparatus of claim 2 , wherein the battery is charged to meet the determined potential propulsion power on the uphill grade with only an incremental engine output power amount.

5. The apparatus of claim 1 , wherein responsive to at least one of the external static and external dynamic information indicating an increase in vehicle speed at the particular location and the determined potential propulsion power based on the increase in vehicle speed, the battery state of charge module is structured to facilitate a charging of the battery in advance of the particular location.

6. The apparatus of claim 4 , wherein the battery is charged to meet the determined potential propulsion power at the particular location without increasing an engine output power amount.

7. The apparatus of claim 1 , wherein responsive to at least one of the external static, external dynamic, and internal information indicating a decrease in vehicle speed at the particular location and the determined potential propulsion power at the particular location, the battery state of charge module is structured to facilitate a discharging of the battery before the particular location.

8. The apparatus of claim 1 , wherein responsive to at least one of the external static and external dynamic information indicating that the particular location coincides with a regulated zone, the battery state of charge module is structured to manage the state of charge in accord with a zone regulation associated with the regulated zone and the determined potential propulsion power.

9. The apparatus of claim 8 , wherein the zone regulation includes at least one of a permissible vehicle noise level, an engine braking regulation, and an emissions regulation.

10. The apparatus of claim 1 , wherein responsive to at least one of the external dynamic information and external static information indicating at least one of a traffic condition and a weather condition that is determined to affect operation of the hybrid vehicle, the battery state of charge module is structured to facilitate selective charging and discharging the battery before reaching the traffic and weather conditions.

11. The apparatus of claim 1 , wherein the battery management module further includes a cost management module, wherein the cost management module is structured to receive at least one of a market characteristic and a market regulation at the particular location at the particular time, and wherein the battery state of charge module is structured to manage the state of charge of the battery based on the at least one of the market characteristic and the market regulation to reduce a cost of operation of the hybrid vehicle.

13. The apparatus of claim 12 , wherein the battery management module manages battery charging from an external source based on at least one of the market regulation and market characteristic.

14. The apparatus of claim 11 , wherein at least one of the market characteristic and market regulation includes an indication of at least one of a location of charging nodes for an electric power grid and a fuel price.

15. The apparatus of claim 1 , wherein the battery management module is further structured to manage the state of charge of the battery based on a determined need for and usage level of one or more active aerodynamic devices at the particular location.

16. A method, comprising:
receiving, by a controller of a hybrid vehicle, at least one of internal hybrid vehicle information, external static information, and external dynamic information;
determining, by the controller of the hybrid vehicle, a propulsion power for the hybrid vehicle at a particular location at a particular time based on at least one of the internal hybrid vehicle information, the external static information, and the external dynamic information;
determining, by the controller, a current state of charge of a battery, wherein the battery is operatively coupled to an electric motor in the hybrid vehicle; and
managing, by the controller, a state of charge of the battery at the particular location at the particular time based on the current state of charge and the determined propulsion power;
wherein responsive to determining a downhill grade at the particular location, the managing includes:
