Electric vehicles are increasing day by day because of its low battery cost and good battery capacity compared to other technology. Increasing automotive growth in electric vehicles also increases the automation to use it.Graphical User Interface for electric vehicles with a full -blown touch screen will become more easy to use with t he introduction of fast charging st ations. The approach shown to build HMI use Texas Instruments kit and CCS software. The TM4C123GH6PM processors p rovide scalability it also provides different processing speeds along with compatible software to build low – to high -end applications, and prov ides connecti vity with various peripherals required for EVSE HMI, such as universal asynchronous receiver/transmitter (UART) and CAN.
Along with this processor touch screen display K350QVGA (Texas Instruments) is used to test the output screen . Index Term s: Human Machine Interface, Code Composer Studio, Texas Instruments.
The market for electric vehicles (EV’s) is emerging where the interest is higher than ever before (Office of Energy Effic iency & Renewable Energy, 2016) [1].
The global act ivity concerning EV’s is increasing due to the strive of reducing greenhouse gases (NASA, 2016), as well as car batteries are getting more efficient than before The EV’s on the market are today charged with a cord that is plugged into the car. The negative aspects with the cord is that it reacts badly to altering weather and air temperatures, as well as if forgetting to plug -in; the car will be powerless.
As the number of EV is increasing day by day on the other hand charging demand also increases . H ence , the charging infrastructure as well as efficient Inductive Power Transfer (IPT) need to developed to meet such requirement for sub stantial operation of the EVs.
For instance, in [2] the United States (US), and Bhutan has taken initiative to build cha rging stations in different regions to provide easy charging services and promote the growth of electric vehicles. The installation of charging stations will add burden on the power grid, and the high charging loads of fast EV cha rging stations will degr ade the distribution network and its operating parameters . The uncoordinated charging of EV’s will degrade the voltage profile, peak load during EV charging and some of the harmonic distortions. Delayed Charging also provides some consequences similar to uncontrolled Charging. In the industrial automation human -machine interaction plays an important role, the user interface is the process where interaction betw een humans and machines takes place [ 2]. The major goal of user machine interaction in human mach ine interface is effective operation of machine and easy control of machine and feedback/status of operations from the machine which signals the operator to make different operational decisions accordingly.
In other words, The HMI gives easy way to intera ct with machine by using its instruction coding language and get our work done by machine. It also provides how hardware and software systems can be designed to expand the human control. HMI products are developed to make machine operation easy, by produci ng optimal outputs. Before HMI was introduced it include the Batch Interface, Command Line User Interface, and the Graphical User Interface (GUI) for industrial automation applications, which is used nowadays in HMI display panels to make user friendly sys tem.
This paper mainly focus on building graphical user interface for electric vehicle charging station. Many approaches to build GUI is discussed in later section. Final i mplementation is carried using Code Composer S tudio IDE and hardware kit from Texas Instruments. This Graphical User Interface provides basic operation required to charge EV with different optio ns for charging or payment to the user. Moreover this application can be further used with mobile application to book the charging slot or search for free charging station nearby etc.
Graphical User Interface for Electric Vehicle
MassTech DC charging station is mainly uses SETQCY series for fast charging of electric vehicle .IP54 standard is used to design the produ ct and install with waterproof and dustproof. This DC fast charging sta tion has charging interface, human -machine interface, system communications, billing and ot her parts, modular design, installation is easy , simple oper ation and maintenance , and the cha rger with the use of electric vehicles outdoor DC fast charge ideal choice . [9].
HMI display screen of DC charging station of Electway DC charger comply with the CHAdeMO technology to charge EV.different protocols are used to communicate between off board conductive charger a nd battery management system to meet the CHAdeMO 0.9 version. The charger may communicate with battery management system (BMS) of the electric car , it may complete charging according to the message of the BMS.
EVlink quick charging stations from Schneider electric Fig. 3. HMI display s creen of Schneider Electric DC charging station The above fig. shows the EVlink quick charging stations with 50 kW charging power. This charging station allows vehicles compa tible with this version to recharge the EV in less than 20 minutes. Depending on the options selected, EVlink quick charging stations offer the following functions [10].
The Tiva C Seri es Evaluation Board TM4C129GXL has ARM Cortex M4 as the main Controller.it is low cost platform for various applications. The Tiva Launchpad includes TM4C123GH6PMmicrocontroller,USBinterface( 2.0),motio n control PWM module.it also includes user buttons and LED(RGB) that can be programmed according to the custom application. The Evaluation board has two stackable headers (40pin booster pack connector) that is used to interface the different Booster pack directly. There is no need of any external wire interfac e for such booster pack and other peripherals. Debug USB port on right side of board is used for program debugging.USB micro connector is used to connect board with the system.
The K350QVGA display is a booster pack from TEXAS Instruments which can be directly used with any Launchpad or evaluation board.it is easy to use and easy to plug in module. This module can be directly used with microcontroller to develop applications w hich needs touch screen color display for displaying output parameters.it has resistive touch screen. The basic features of this display is listed below, includes,
The above fig. shows the experimental setup for this application project. The touch screen display from Texas Instruments is used to show results.TM4C123GH6M Launchpad is use d to interface this display. Coding is to be done using code composer IDE which provides a better solution for Texas kit to be easily interfaced and use for any application
This paper introduced the building of human machine interface using Texas controller and code composer studio and also selection of HMI screen based on different selection criteria from different manufactures. The literature activities showed that resistive touch is best for this application hence K350QVGA t ouch screen is used to test the display output. Code composer studio provides a good interface with Texas instruments kit and booster pack which makes the design more simple and easy to use .
