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

This processor-based reference design helps speed time to market and helps customers design cost-effective human-machine interface (HMI) solutions for electric vehicle (EV) charging infrastructure or EV power supply equipment (EVSE). This reference design demonstrates the two-dimensional (2D) Qt graphical user interface (GUI) common to EVSE HMI, as well as TI processor capabilities for software-rendered graphics. The AM335x processors provide scalability and a variety of processing speeds and compatible software to meet the needs of low-end to high-end applications. They also provide ample connectivity, including key peripherals required for EVSE HMI such as universal asynchronous receiver/transmitter (UART) and CAN).

characteristic

• ● Four example screens for the charging station option (using software accelerated graphics and Qt)
• ●Support resistive touch screen
• ● Supports 480 × 272 resolution on the supplied 4.3-inch LCD, but expandable to 2048 × 2048 on other displays
• ● Built on TI's Processor SDK-Linux for easy expansion to other Sitara processors
