Smart and Compact Battery Management System Module for Integration into Lithium-Ion Cell for Fully Electric Vehicles

SMART-LIC

Smart and Compact Battery Management System Module for Integration into Lithium-Ion Cell for Fully Electric Vehicles

Call for proposal: 
FP7-2011-ICT-GC
Link to CORDIS:
Background & policy context: 

The project has officially started during the May 1st 2012 and has an intensive communication with regular meetings.

The SMART-LIC project has very ambitious targets like integrating the battery management system (BMS) in a single battery cell (or module) as well as develop accurate state of health (SoH) indicator based on an integrated electrochemical impedance spectroscopy (EIS) and this with a “radical overall cost reduction”. This should increase precision, lower system complexity (reduced wiring), increase reliability and result in radical total cost of ownership (TCO) reduction.

Impedance measurements is highlighted as it will be implemented on a vehicle. It will be a breakthrough if the validity of the SoH measurements is confirmed. There are currently no large deviations against the workplan.

The project is making good progress. The intermediate results presented during the review meeting clearly demonstrated the level of activities performed in the first year of the project.

Objectives: 

Smart & Compact Battery Management System Module for Integration into Lithium-Ion Cell for Fully Electric Vehicles SMART-LIC addresses the development of a new Battery Management System concept aiming at:

- Lower system complexity by a radical reduction of wiring and connectors cause of EMF emissions and major source of malfunctions - Higher efficiency of the battery packs because of the local control

- Increased overall reliability and safety such that early determination of irregularities and failures of the actual battery cells is possible and not impaired by defects in wiring connectors and remote electronics

- Increased flexibility of the overall energy-power routing such to assure that all cells could perform at their maximum rating independently from the rating of the others.
- Radical overall cost reduction of the overall BMS because of reduced cabling and connectors as well as simplification of the electronics

- Increased precision in determining the states of charge, of health, and of function of the individual cells and of the entire battery by applying a new battery model based on electrochemical impedance spectroscopy (EIS)

- Reduced maintenance of the battery packs assured by the monitoring of the single cell (macrocell) with the possibility to switch it off from the rest of the pack.

- Reduced cost of ownership for the end user due a significant increase in battery lifetime caused by the improved management on cell level.

Methodology: 

The ambitious objectives are obtained by realizing the BMS module as a system-in-package (SiP) directly integrated into the lithium-ion cell for fully electric vehicles by using advanced packaging technologies. Early demonstration of the technology will be made by preparing specific battery packs to be installed both on a commercially electrified vehicle and on a FEV of new concepts.
