solution and a capacitive touchscreen is the easiest way for drivers to interact with stations. Displays open up possibilities for interconnectivity features like email and text alerts as inputting contact details or signing into an account is super simple when working with a capacitive touch display. Displays also off er a great host of possibilities for user troubleshooting. If a car has been plugged in incorrectly, prompts on how to resolve issues can help drivers get connected without the need for technical support. For a trustworthy and experienced supplier of off -the-shelf display components for use in your systems, Display Technology off ers a wide range of smart display solutions. For charging stations, it recommends the POS-RP-070-00-PRO CE- certifi ed 7-inch monitor from Distec. The POS-RP uses a Raspberry-Pi-based
control board to off er snappy and highly- confi gurable operation. For charging stations, the ten-fi nger PCAP touchscreen makes it easy for drivers to use, with the added responsiveness of capacitive touch control improving usability. As charging stations will need to withstand the environmental requirements of outdoor operation, water and dust resistance is a must. Distec has designed their POS-RP to comply with the IP65 standard. Display Technology off ers a wide range of monitors from 15.0”- 31.5” within the POS- Line range with full-HD capacitive touch display specially designed for use in public amenities. With a standard display brightness between 400-700cd/m2
to enhance up to 2000 cd/m2
– and the possibility – users will
have no issues viewing and interacting with the monitor in sunlight. Whilst the FHD resolution contributes to the premium feel and improves UI aesthetics. These displays are specially designed for

system designers to adapt its software to meet the requirements of the application. Designers can fl ash custom fi rmware to these displays for full functionality and communication with the other components of a charging station.
Embedded systems For the most-effi cient charge possible, the communication between the charging components and an electric vehicle is extremely important. Handling the necessary transfer of information between the vehicle and the power components is the role of the embedded system. One of the main roles of an embedded system in an EV charging station is the handling of power output. By varying power delivery to a vehicle, a charging station can optimise the charging to manage the temperature ensuring safe operation and improve the overall charge time of the vehicle.
Embedded systems can analyse data
provided by an EV to optimise its charge, and more powerful computers can use AI- enhanced modelling to better predict charge patterns.
Embedded systems can be connected to the Internet either wirelessly or through Ethernet, allowing for a multitude of online possibilities. A powerful and robust embedded system for use in EV systems is the AXIOMTEK IFB125. This computer is powered by the Freescale
i.MX6UL processor using the ARM Cortex-A7 architecture. To meet the IoT needs of EV vehicles, the IFB125 supports multiple communication interfaces including LAN, serial and USB, whilst the PCI Express Mini card slot allows for easy installation of a Wi-Fi card for wireless connectivity. Another embedded system for EV
charging is the AXIOMTEK CAPA311. At the heart of this system is the Intel Atom x5-E3940. With support for up to 8GB
memory, HDMI output and two full-size PCI Express Mini Card Slots, this SBC is a perfect component for a high-tech DCFC.
PowerPro for Artesyn iHP For high-end EV charging stations, system designers can benefi t from digital control and device communication. The Artesyn iHP includes an optional cloud-based power management tool known as PowerPro. It comes in the form of a power module for the iHP Series of modular power supplies. Installing the PowerPro unlocks the use of a high-level software graphical user interface to control and monitor an iHP power supply. PowerPro facilitates digital control through a whole slew of diff erent industrial protocols, including PMBus, RS- 485 and Ethernet. For fl eets of DCFCs for EVs, technicians
can remotely monitor the power parameters of iHP-equipped charging stations, and control most, if not all, of the readily accessible and confi gurable functions on the power supply. The GUI is held in the cloud and can be accessed on any device connected to the Internet. PowerPro can connect multiple iHP-equipped systems, allowing technicians to manage their entire deployment of EV charging stations from one location, remotely. PowerPro can monitor power data in
real time and can help technicians monitor what time of the day drivers tend to use the charging stations and how long they usually stay for a charge. System designers can then respond to usage patterns by executing custom control routines – resulting in a positive feedback loop between driver behaviour and power management tweaks.
