NUC980 Microprocessor Reference Application: Charging Pile Solution

[NuvotonMarcom]

Electric vehicles have developed very rapidly in recent years. Whether or not it is for small motor vehicles or electric cars, the market has sprung up. Because of this, there is a significant increase in demand for electric vehicle charging systems, as well as the need for charging piles in public areas. Department store parking lots, general roadside parking, and private parking lots all need charging piles to serve the vast amount of electric vehicle users. In addition to the charge-control function, charging piles also need functions that help calculate the amount of electricity used as well as billing-related matters. Therefore, network statistics and data collection are also important functions for charging piles.

Nuvoton NUC980 Ethernet series has a maximum of 128MB DDR built-in memory that can easily run Linux OS, and it is also equipped with LQFP MCP (Multi-Chip Packaging) technology that allows easier hardware designing without having to worry about the synchronization issue for high-speed DDR memory wiring. It also supports 4-channel CAN BUS that can connect a maximum of 4 charging piles, so it has the ability to control four charging piles simultaneously using a single system. NB-IoT or 4G LTE can also be connected through the USB host interface to achieve the need for remote collection, and it provides a maximum of two 10/100 Ethernet MAC and RMII interfaces as well as a hardware encryption engine and up to 10 UART communication ports, etc., able to provide the requirements for charging pile control applications.
