With the popularity of electric vehicles and the enhancement of environmental awareness, charging piles are an important part of electric vehicle charging equipment. The charging pile industry is developing rapidly, and a large number of applications in the consumer market have also created a growing market demand. Therefore, product functions, reliability, safety and other requirements have become particularly important, and the use of traditional single-chip microcomputer products cannot meet the needs of intelligent control of charging piles. This article details the charging pile application solution based on Mil STM32MP135 core board.
The STM32MP135 series microprocessors are used to design intelligent embedded charging piles for electric vehicles, and intelligent control of complex functions is realized through "command" 8-bit and 16-bit microcontrollers.
In the application of smart charging piles, the STM32MP135, which has high cost performance, low power consumption and high reliability, has the following advantages:
Running Linux system, real-time processing of data and tasks Charging piles usually consist of a main control system and multiple subsystems. The subsystems generally include power supply system, charging gun, electricity meter, display screen, card reading module, and temperature detection system.
In charging pile applications, various complex tasks need to be effectively handled, such as data processing, communication and user interface control. The STM32MP135 chip is equipped with a Cortex-A7 processor with an operating frequency of up to 1GHz, which allows customers to easily run Linux systems on the ST chip, providing powerful data processing capabilities.
Multiple peripheral interfaces for easy connection of external devices
During the use of the charging pile, it is necessary to monitor and control the battery status, charging process and communication status in real time, and exchange data with other systems. The STM32MP135 chip integrates a rich set of peripheral interfaces, including UART, SPI, I2C, USB, CAN FD, dual Gigabit Ethernet, etc. can easily connect various sensors, communication modules, displays and other external devices in the charging pile.
