This research proposes designing and implementing a bidirectional control in a battery operating in charge and discharge. A battery without a suitable control algorithm based on the state of charge (SOC) parameter in the charge and discharge modes of operation can present a continuous degradation and higher costs because it would not fully supply the demand, and the more cycles of operation, the higher the degradation will be. The battery, distribution generator, and bidirectional DC-DC converters are simulated and implemented in the Typhoon HIL (Hardware in the Loop) system. The designed controller is implemented on a DSP programming board, where its operation is in real-time and preliminary tests are real. This is a process before the industrialization of a technological product. The proposed controller is based on traditional Proportional Integral (PI) voltage and current controls acting immediately. In addition, a SOC constraint is implemented to conserve the battery life so that the battery does not degrade quickly. This constraint will depend on the battery operation and mode of operation. The controls are tested for different load (demand) values, the battery’s automatic action of power distribution, and the SOC controls the distribution generator.
