Attendees

Meeting Notes

• Discussion on Planned Demo/PoC for CES 2023:
  • Mentioned that the Network Reception for COVESA can be a good session for the COVESA team (led by Mobis) to showcase the first level EV Power Optimization dataset on January 5^th at CES 2023.
  • Proposed that EV Power Optimization Use Cases related to HVAC, Lighting and Climate Control can be taken to CES 2023.
  • Shared details regarding registration for CES 2023.
  • Outlined Plan for development of PoC.
• Demonstration of Approach for Integration with VSS:

• • Showcased the VSS Model developed and mentioned that COVESA VSS team suggested that existing VSS Modules should be used to include EV Power Optimization.
  • Suggested that signals developed should be able to clearly indicate the difference between Normal mode and Power Optimized mode. 
• Plan for Collaboration:
  • Planned Tasks for development of PoC outlined.
  • Tasks assigned to two teams. The first team will work on creating a UI for the PoC in the digital.auto playground. The second team will work on creating an Excel Spreadsheet showing data on Power Optimization of different EV Systems.
• Topic for Next Week's Meeting:
  • Discussion on Excel Spreadsheet prepared for the planned PoC. 
  • Discussion on UI Development for the planned PoC. 

November 16th at 7:00am PT, 10:00am ET, 1600 CET

Agenda

• Overview of Project and Technical Concept.
• Plan to Integrate with VSS. 
• Queries and Suggestions from Participants.

Attendees

Meeting Notes

• Explained the following:
  • Power Optimization Project Technical Concept in detail including the Architecture, Parameters, Use Cases, VSS Signal Integration (Additional Signals recommended) and applicability to different Automotive Systems/Modules. 
  • Proposed that VSS Signals can be added in two different ways for this project: 
    • Add in the Existing VSS Modules in the Infotainment Category. 
    • Add a separate VSS Module for EV Power Optimization.
• Views from Participants:

• • In general the concept is accepted and further study is agreed.
  • Suggested to create a first level dataset based on estimates and develop it further:
    • Participants mentioned that they are willing to share resources for this activity.
    • Potential candidate to be presented in CES 2023 if such date would be available.
  • Expressed opinion that the EV Power Optimization technical concept can be applied to all EVs globally and can be customized to cater to the requirements of OEMs and Tier 1s.  
  • Possible to explore additional product lines for Power Optimization.
• Topic for Next Week's Meeting:
  • Discussion on possible collaboration for further development of VSS Signals and Dataset.
  • Discussion on approach for VSS Signal Integration for this Project.

EV Power Optimization Proposal presented during COVESA Fall AMM conducted from18th to 20th October:

• EV Power Optimization Project Proposal and premise were presented.
• Technical aspects of the proposal along with Use Cases and Parameters Effecting Travel Range were explained.
• Guidelines for Power Optimization, currently proposed for IVI module, can be extended to many other modules of the vehicle.
• Discussed Opportunity for reutilization by industry Partners related to EV Power Optimization.

EV Power Optimization Project Proposal:

Overview

Framing Question:   How can we increase the travel range in EV for fixed battery capacity?

EV Power Optimization Project Proposal Summary

• The proposal team aims to initiate and lead a dedicated EV power optimization Interest group within COVESA.
• An initial seeding project aims at :
  • Develop standard specification for power optimization.
  • Demonstrate features/scenarios by POC.
• The proposal team would like to drive this project if other OEMS participate in defining/improving the guidelines for multiple ECU’s.
