Battery management and control system for underwater vehicle

Abstract

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.

Description

technical field [0001] The invention relates to a battery management and control system, in particular to a battery management and control system for underwater autonomous vehicles. Background technique [0002] With the development of ocean exploration technology, the requirements for the endurance of underwater vehicles are increasing day by day. Therefore, in a limited volume, choosing a battery with high energy density and an optimized battery combination has become a solution. However, the parallel connection of batteries often causes differences in the characteristics of the batteries during charging and discharging, which easily shortens the life of the batteries. At the same time, improper operation or improper use of high-energy-density batteries is prone to explosion, causing damage to expensive components inside the underwater vehicle, and even causing the cabin to crack and leak. Therefore, it is particularly important to design a set of battery management and c...
