Abstract. At present, the research of the power lithium battery management system which was applied to the underwater robot is still in the initial stage. The lithium battery management has become one of the main contents of the development of the underwater robot technology. When the use time of rechargeable battery is short, various factors will reduce the life of the battery. Due to the problem of materials, the price of the battery is limited. Effective management of lithium battery can improve the use efficiency of the battery. In addition, the safe and effective use of electricity has great significance for the energy of the pool, which can extend the battery life and improve the reliability of the battery. The main functions of the battery management system were introduced in this paper. The hardware management system, temperature sampling, temperature detection circuit and charging module of the lithium battery were mainly designed.

1 Introduction For AUR, energy system plays an important role in long-term, deep-sea and complex environment detection. Energy system is an important part of AUR. Power quality directly affects the performance of the whole system and the service life of hardware. As the main form of power driven AUR, battery is an important part of the energy supply of AUR. The selection of battery needs to be considered in many aspects. In addition to energy density and energy/volume ratio, utilization efficiency, ambient temperature, noise, gas leakage during charging and discharging, safety performance of water closed environment, environmental pollution and other factors should also be fully considered. Power management system is an important part of AUR energy system, which is responsible for real-time monitoring and management of AUR energy. In order to construct the AUR precise integrated positioning system in the deep-sea complex environment, multi-sensor device is used [1]. The research of the power lithium battery management system applied to the underwater robot is still in the initial stage, and the lithium battery problem has become © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021 Q.
