Electric vehicle interface controller

Electric vehicle interface controller


A Human Machine Interface (HMI) is an interface which provides interaction between a human being and a machine. Human machine interfaces are applied in a wide range of applications, from interactive control panels at industrial factories to the steering wheel and control buttons found in a vehicle to operate it.

HMI is an essential ingredient to effectively control and monitor the digital devices that humans interact with every day. Designing such interfaces are a challenge, and requires a great deal of work to make the interface functional, accessible, pleasant to use, and logical. The challenge is designing and developing HMI solutions that reliably, efficiently and quickly achieve a person’s goals.

Andromeda Interfaces designs and develops integrated and configurable instrumentation to ensure the safety and performance of electric vehicles.

Their technology starts with a Studio Interface Kit (SIK) which provides an environment for designing and implementing human machine interfaces (HMIs). Once these HMIs are complete they complement them with their Advance Display Interface Modules (ADIMs) to deliver a final solution to customers.

EVIC product overview

With this design approach Andromeda Interfaces are able to achieve rapid design and development of HMI products to enable to quickly apply them to a variety of applications.

The Milky Advance display interface modules (ADIM)

ADIM-Milky is a scalable hardware platform that allows to apply HMI graphics, which are generated from the Studio Interface Kit (SIK) to meet customer’s requirements and specifications. It is also called EVIC for Electric Vehicle Interface Controller.

EVIC electrical specification

EVIC is based on the design of a system-on module architecture using Freescale’s i.MX25 multimedia applications processor, and the printed circuit board (PCB) design is a carrier board that supports various inputs/outputs (I/O) and communication interfaces.

Milky electrical specification

Integrated display device connects to CAN 2.0B network and retrieves the following data:

  • Battery Cell Temperatures (Min and Max)
  • Battery Cell Voltages (Min and Max)
  • Traction High Voltage (VDC)
  • Traction Charge and Discharge Amperage (Amps)
  • Battery State-Of-Charge (SOC)
  • Motor Temperatures (Celsius)
  • Motor RPM
  • Motor Voltage (VDC)
  • Motor Charge and Discharge Amperage (Amps)
EVIC Combo Label

EVIC supports liquid crystal display panels up to 800×480 wide video gate array (WVGA) resolution with resistive touch screens.

EVIC mechanical specification

EVIC.Combo display comes standard with enclosure design that protects the vibrant LCD screen and internal components while including mechanical features for ease of installation.

Romain’s opinion:
This kind of interface plays a huge role in the way the user will drive an electric vehicle and then in the range the vehicle will reach. I believe that adding a social dimension to these data would be an enabler for the spread of the EVIC. For example, one could compare his driving range on a given driving cycle with his friends and create a kind of contest. Do you think that people would buy this HMI or rather a Smartphone application to have these data available?

    Do you have a screen that displays us/imperial?
    Can you make a harness to receive ev info but display to an ipad?
