The invention discloses a battery management and
control system for an
underwater vehicle. The battery management and
control system comprises a main
control unit, a plurality of battery blocks and charge circuits, wherein the plurality of battery blocks are sequentially connected with one another in series; each battery block comprises a management
control unit; each management
control unit comprises a sampling circuit, a
short circuit protection circuit, a temperature detection circuit, a battery balance circuit, an over-charge and over-
discharge protection circuit, an anti-
backflow circuit and a
voltage collection circuit; and the charge circuit, the sampling circuit, the temperature detection circuit and the
voltage collection circuit in each management control unit all are connected with the main control unit. In the process that an autonomous
underwater vehicle enters a
docking station for charging, parameters of a
voltage, a current, a temperature and the like of a battery are transmitted to the main control unit; the main control unit transmits the parameters to the
docking station through a wifi
signal; the
docking station transmits a feedback
signal to a
shore-based upper computer for carrying out monitoring and operation. The
system disclosed by the invention carries out secondary protection on the battery, and is safe and reliable; normal use of equipment in the
underwater vehicle is ensured; and the lifetime of the battery can be prolonged.
