STM32 embedded development, Mil STM32MP135 core board helps the development of charging piles
[Copy link]
With the popularity of electric vehicles and the enhancement of people's environmental awareness, charging piles, as an important part of electric vehicle charging equipment, are developing rapidly in the charging pile industry, and a large number of applications in the consumer market have also led to a growing market demand. Therefore, product functions, reliability, safety and other requirements have become particularly important, and the use of traditional single-chip products cannot meet the needs of intelligent control of charging piles. This article will introduce in detail the application of charging piles based on the Mil STM32MP135 core board.

The STM32MP135 series microprocessor is used to design the intelligent embedded charging pile for electric vehicles, and the intelligent control of complex functions is realized by "commanding" 8-bit and 16-bit microcontrollers. In the application of intelligent charging piles, the advantages of the STM32MP135 with high cost performance, low power consumption and high reliability are as follows:
Run Linux system to process data and tasks in real time
Charging piles are usually composed of a main control system and multiple subsystems, which generally include power supply system, charging gun, electric meter, display screen, card reader module, temperature detection system, etc. In charging pile applications, it is necessary to effectively handle various complex tasks, 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 the Linux system on the ST chip and provides powerful data processing capabilities.

Secure encryption to protect data
As a device involving high-voltage electricity, the safety of charging piles is of vital importance. The STM32MP135 chip provides a wealth of security features, including hardware encryption engine, secure boot and hardened boot, as well as external access control. These features can help charging piles resist various attacks and ensure user safety and data integrity.
Low power design to reduce energy consumption
Electric vehicle charging piles need to run for a long time and consume a lot of power, so power consumption optimization is very important. The STM32MP135 chip has low power consumption characteristics and can automatically adjust the power consumption level according to demand to extend the working life of the charging pile and reduce energy consumption.
Flexible software support
ST provides a wealth of software support and development tools, including development boards, Linux operating systems, and development environments, etc. These tools provide developers with the ability to quickly and efficiently develop and debug charging pile applications.
