One embodiment of the invention includes a battery sense system. The system includes a temperature sensor configured to measure a temperature of a battery and a memory configured to store predetermined data associated with steady-state and transient behaviors of the battery relative to a depth of discharge (DOD) of the battery. The system also includes a controller configured to measure a voltage of the battery and to calculate a state of charge (SOC) of the battery based on the voltage, the predetermined data, and the temperature.

System and method for sensing battery capacity

Controllers and methods to manage a battery, in which a controller estimates scale factor and a steady state current rate according to multiple battery voltage values and a steady state model during steady state operation, and estimates the current rate according to a battery voltage value, the scale factor, and a dynamic model of the battery during dynamic operation, and the controller estimates a remaining capacity of the battery according to the current rate, without requiring controller reconfiguration for different batteries.
