Design knowledge of power lithium-ion battery system

The power lithium-ion battery system mainly refers to the energy storage device that supplies power to the electric vehicle, which is composed of one or more battery packs and a battery management system. The power lithium-ion battery system is a complex system integrating battery technology, electronic control technology, structural design technology and thermal energy analysis technology, but the most important thing is the design of software and hardware. The specific subcontinent power lithium-ion battery case will be analyzed for you : Power lithium-ion battery system design-software design and hardware design 1. Hardware design The hardware is mainly composed of data acquisition unit (acquisition module), central processing unit (main control module), display unit, balance unit detection module (current sensor, voltage sensor) , Temperature sensor, leak detection), control components (fuse, relay) and other components. The central processing unit is composed of a high-voltage control circuit and a main control board. The data acquisition unit is composed of a temperature acquisition module and a voltage acquisition module. CAN field bus technology is a common technology to realize information communication. Software design 2. Software design The software design functions of the power battery management system generally include voltage detection, temperature acquisition, current detection, insulation detection, SOC estimation, CAN communication, discharge balance function, system self-check function, system detection function, charging management, Thermal management, etc. The hardware design supports software design functions, such as the MCU module that collects, analyzes data, and receives control signals; the current detection module collects the charge and discharge current during the charging and discharging process of the battery pack. Power lithium-ion battery system design software design and hardware design, do you understand? Power lithium-ion battery system design is based on the premise of meeting the power requirements of the vehicle, while considering the internal structure and safety management design of the battery system itself.
