1. A system for providing power to a vehicle power network, comprising:

  • an energy storage device connected to the power network;

    a sensor connected to the energy storage device for measuring a state of the energy storage device during a rest period, wherein the rest period corresponds to a time span during which a current through the energy storage device is reduced to a level that enables an estimation of a state of the energy storage device; and

    a controller that receives data from the sensor and estimates the state of the energy storage device based on data, wherein the controller establishes the rest period by optimizing between minimization of disruption to normal vehicle operation and a need to update a measurement of the state of the energy storage device.
