Measuring system and power management of the Guanay II AUV

Abstrac t This paper presents a measurement system and energy management for Guanay II autonomous underwater vehicle (AUV). The system performs the measurement, monitoring and control of the state of charge of the batteries, allowing simultaneous charging of all batteries from outside of the vehicle, and a wireless connection/disconnection mode. Considering the type of batteries used in the vehicle, it is used the current integration as methodology for measuring the charge level of the battery. Laboratory and vehicle navigation tests performed have validated the correct operation of the system and the reliability of the measured data. These data are sent to the mission control of the vehicle in order to optimize and guarantee its navigation. Keywords– state of charge, batteries, AUV, Ni-Cd
