Human Machine Interface (HMI) for EV Charging Infrastructure Reference Design

TIDEP-0087

Design files

Overview

This processor-based reference design facilitates a quicker time to market and helps customers design cost-effective, human machine interface (HMI) solutions for electric vehicle (EV) charging infrastructure or EV supply equipment (EVSE). This reference design showcases a two-dimensional (2D) Qt graphical user interface (GUI), which is typical for EVSE HMI, along with TI processor capabilities for software-rendered graphics. The AM335x processors provide scalability with various processing speeds, compatible software to satisfy low-to high-end applications, and ample connectivity with the key peripherals required for EVSE HMI, such as universal asynchronous receiver/transmitter (UART) and CAN.

Features

4 example screens of charging station options using software accelerated graphics and Qt
Resistive touchscreen enabled
Support for 480x272 resolution on included 4.3 inch LCD, but scalable up to 2048x2048 on other displays
Built on TI’s processor SDK-Linux for scalability to other Sitara processors
