[Abstract]:Lithium iron phosphate battery is a new type of lithium ion battery developed in recent years. Compared with the traditional lead-acid and Ni-MH batteries, it has high capacity, high output voltage, good charge-discharge characteristics, high current shock resistance, and stable electrochemical performance. It has the advantages of wide working temperature range, no toxicity, no pollution to the environment, but at the same time, there are also problems such as battery consistency, batteries being afraid of overcharging, etc. Therefore, it is necessary to cooperate with the battery management system to manage and protect it in practical use. The battery management system power supply system involved in this paper is mainly designed for the emergency power supply field of coal mine shelter chamber. A battery management system for lithium iron phosphate battery based on 24V30A is developed. The whole system uses multi-level control system architecture, which can be used separately, and can be used separately. The emergency power supply for mining has its own particularity. In order to ensure the reliability of the system, shorten the research and development cycle and reduce the cost of the research and development, the safety evaluation technology is introduced to analyze the effectiveness of the design of the whole system and the functional circuits to ensure the perfection of the function. The reliability of the circuit and the perfect combination of electronic engineering and safety engineering. The main research contents are as follows: 1) Research on the performance of lithium iron phosphate battery. Understand the working principle of lithium iron phosphate battery, test the charge of the battery, The characteristics of discharge cycle and temperature provide theoretical basis and control parameter reference for the research and development of lithium iron phosphate battery system. Hardware design. The battery management system based on ARM MAX17830 is designed to solve the problem of short circuit protection under low voltage and high current, multilevel parallel network, Charge and discharge control and multi-channel temperature collection, etc. The battery management system program design is completed around the actual demand of coal mine emergency power supply. The combination of electronic engineering and safety engineering is realized. In the process of research and development, The safety evaluation technology is introduced to analyze the validity and reliability of the designed circuit to improve the stability of the system. At the same time, it also effectively shortens the research and development cycle and reduces the production cost and R & D cost of the product. It promotes the application of safety evaluation technology in the development of electronic products.
