Integrated power system control method and related apparatus with energy storage element

摘要

Systems and methods for controlling a hybrid power architecture to provide fuel or energy savings. Recharge time of an energy storage device (ESD) is reduced through the application of a controlled potential and ESD recharge time management over the life of the hybrid system through manipulation of the ESD charge state window of operation. Fuel or energy savings is achieved by controlling the partial-state-of-charge (PSOC) window of the ESD based on a recharge resistance profile of the ESD and by controlling a charging potential applied to the ESD based on a recharge current and/or the estimated recharge resistance profile of the ESD.

主权项

1. A system, comprising:
an energy storage device configured to store DC electrical power and provide DC electrical power to a DC load; a regulator operatively connected to the energy storage device and configured to convert AC electrical power, from an AC electrical power source, to DC electrical power and provide the DC electrical power to the energy storage device and/or to the DC load; and a controller in communication with the energy storage device and the regulator, and operable to:
direct the regulator to apply a first recharge potential to the energy storage device when a determined recharge resistance value of the energy storage device is below a determined resistance threshold value; anddirect the regulator to apply a second recharge potential to the energy storage device, which is less in magnitude than the first recharge potential, when the determined recharge resistance value of the energy storage device is above the determined resistance threshold value.
