EV Dashboard

Overview

In Electric Vehicles (EVs) and bikes, the dashboard itself is a big factor in the first impressions of a vehicle, and the user experience for drivers. This includes both appearance/styling and practical functionality. Modern (especially EV) vehicles also have a much greater range of information to present to the driver, but it is vital that this is presented in a clear and concise way. Using a graphical display provides these benefits and helps overcome many of the trade-offs with traditional dashboards. The EVE video controllers are an ideal solution for designing an EV dashboard, especially the latest generation BT817A which has AEC-Q100 qualification. Other EVE devices can also be used depending on the application if AEC qualification is not needed.

​Here are just some of the benefits in adding an EVE-enabled touch display:

  • Drive large wide format screens with a variety of shapes and form factors
  • Drive smaller displays for EV bikes such as 4” circular displays or custom shapes
  • Easily create stylish and intuitive user interfaces to improve user perception and experience
  • Design the layout with complete flexibility to make better use of the dashboard real-estate
  • Create dashboard themes such as ECO and SPORT
  • Easily add touch screen control to the dashboard
  • Sound audio tones and alerts to the driver without burdening the MCU
