The system of claim 1, further comprising: a contactor coupled to the starter generator and the battery,wherein the contactor is configured to receive current from the starter generator and provide the current to the battery to charge the battery. 6. The system of claim 1, wherein the battery is charged during a charging cycle, and wherein a charging profile associated with the charging cycle and implemented by at least one of the controller and the regulator provides for a substantially constant current over the course of the charging cycle. 7. The system of claim 1, wherein the plural thresholds or limits associated with the engine or the starter generator comprise a charging profile. 8. An apparatus comprising: at least one processor; andmemory having instructions stored thereon that, when executed by the at least one processor, cause the apparatus to: cause a starter generator to receive power from a battery of a battery system comprising the battery, a controller and a regulator to cause an engine of an aircraft to start,cause the starter generator to provide electrical power to the battery system for recharging the battery during a recharging operation and at least one load, andlimit an in-rush current to the battery resulting from the starter generator providing the electrical power having a substantially constant current to the battery system for the charging of the battery during the recharging operation following the starting of the engine in response to signals provided to the regulator from the controller that relate to determining whether the battery is drawing excessive current during the recharging operation in accordance with plural thresholds or limits associated with the engine or the starter generator. 9. The apparatus of claim 8, wherein the at least one load comprises at least one of: avionics, a motor, lighting, and a fault. 10. The apparatus of claim 8, wherein the instructions, when executed by the at least one processor, cause the apparatus to: cause the starter generator to receive power from the battery to cause the engine to start. 11. The apparatus of claim 8, wherein the instructions, when executed by the at least one processor, cause the apparatus to: cause the battery to be charged during a charging cycle,wherein a charging profile associated with the charging cycle provides for a substantially constant current from the starter generator to the battery over the course of the charging cycle. 12. The apparatus of claim 8, wherein the plural thresholds or limits associated with the engine or the starter generator comprise a charging profile. 13. A method comprising: determining, by a controller comprising a processor, a state of operation with respect to an aircraft engine; andbased on the state of operation, controlling, by the controller, a distribution of current with respect to a starter generator and a battery whereby the starter generator provides electrical power for recharging the battery during a recharging operation,wherein the controlling comprises limiting an in-rush current to the battery resulting from the starter generator providing electrical power having a substantially constant current to a battery system, which comprises the battery, the controller and a regulator, for the recharging of the battery during the recharging operation following a starting of the engine in response to signals provided to the regulator from the controller that relate to determining whether the battery is drawing excessive current during the recharging operation in accordance with plural thresholds or limits associated with the engine or the starter generator. 14. The method of claim 13, further comprising: determining, by the controller, that the state of operation indicates that the engine is being started; andbased on determining that the state of operation indicates that the engine is being started, causing, by the controller, current to be supplied from the battery to the starter generator. 15. The method of claim 13, further comprising: determining, by the controller, that the state of operation indicates that the engine is already started; andbased on determining that the state of operation indicates that the engine is already started, causing, by the controller, current to be supplied from the starter generator to the battery in order to charge the battery. 16. The method of claim 13, further comprising: causing, by the controller, a built-in-test to be performed on at least one of the battery, the starter generator, the engine and the regulator. 17. The method of claim 16, wherein the regulator is configured to control a voltage supplied by the starter generator that is used to charge the battery. 18. The method of claim 13, wherein the plural thresholds or limits associated with the engine or the starter generator comprise a charging profile.
