Analog front-end acquisition system based on battery management

Abstract

The invention belongs to the technical field of battery management, and particularly relates to an analog front-end acquisition system based on battery management, which comprises a multi-channel data acquisition module, an analog front-end unit, an FPGA chip, a storage module, an intelligent label generation module, an intelligent label card reading module, an upper computer, a data abnormity monitoring unit, an alarm module and a wireless communication module. The output end of the multi-channel data acquisition module is connected with the analog front-end unit, and the multi-channel data acquisition module is used for battery data acquisition. The analog front-end unit is used for carrying out filtering, amplification and analog-to-digital conversion processing on received sensing signals, the carrier-to-noise ratio of transmission signals is increased, stable and safe data transmission is achieved between the FPGA chip and the upper computer through the wireless radio frequency identification technology, mechanical or optical contact between an identification system and a specific target does not need to be established, penetration and barrier-free reading can be achieved, the intelligent label can be repeatedly used, updating of information data is facilitated, and identification is accurate and flexible.

Description

Technical field [0001] The present invention relates to the field of battery management, and is specifically a simulated front-end acquisition system based on battery management. Background technique [0002] In recent years, with the development of various hybrid vehicles and electric vehicles, the performance requirements of the car battery have become higher and higher. In particular, the plug-in hybrid vehicle (PHEV) and electric vehicles (EV) are more likely to compare the battery capacity compared to the gasoline hybrid vehicle, while the charge and discharge electrical loss and self-discharge requirements are as small as possible. Therefore, the status of the lithium ion battery is increasingly important. [0003] Lithium-ion batteries have become the preferred power supply of electric vehicles with high energy density, high power density, long cycle life, good security. In order to achieve a certain voltage, power, and energy level, multiple unit batteries need to be used...
