A controller for a hybrid electric system such as a hybrid electric vehicle includes a load, a battery, and a controllable source of auxiliary electricity. The state of charge (SOC) of the battery is estimated, and an error signal is generated which represents the difference between a desired and actual SOC. The SOC error signal is processed by at least integration, to produce a source signal representing the desired auxiliary source current. A second error signal is generated between the actual current from the auxiliary source and the desired current from the auxiliary source. The second error signal is processed, at least by integration, to produce a control signal for controlling the auxiliary signal source.
