Abstract: Apparatuses, systems and methods for implementing a downhole alternator assembly are disclosed. In some embodiments, a downhole alternator assembly comprises a casing; a turbine disposed within the casing and actuated by a drilling fluid flow; and a rotor disposed within the casing. The rotor includes a cylindrical rotor core rotated by the turbine; a plurality of permanent magnets disposed in the cylindrical rotor core; and a drilling fluid channel extending axially through the center of the cylindrical rotor core. The downhole alternator assembly includes a stator disposed within the casing. The stator includes a cylindrical stator core disposed concentrically between the cylindrical rotor core and the casing; conductor windings within the cylindrical stator core; and a plurality of radially distributed fluid channels extending axially within the cylindrical stator core between a front end of the cylindrical stator core and a back end of the cylindrical stator core.

Abstract: The invention addresses to a system and method that allow controlling the individual power flow of each battery, being indicated for energy accumulator systems of the electrochemical-battery type, solidly connected to the electrical grid, respecting each of its characteristics during operation. Thus, if the batteries present different states of charge, the system will be responsible for draining from each battery only the amount of energy that can be used. For different states of health, charge and life, the performance and discharge capacity are preserved. For degraded batteries, the system allows their replacement without the need of replacing the entire bank, including batteries with different technologies.
