EU research project supports the large scale deployment of electric vehicles

Electric vehicles are gaining more and more supporters each day. Nevertheless some users find it difficult to buy electric cars because of challenges such as cost, driving range or infrastructure support. Several of these challenges are directly connected to the battery, the central element of the full electric vehicle (FEV).

In conventional cars the amount of fuel is precisely known and the energy can be efficiently utilized out of the tank to the last liter. In the case of electric vehicles, the high-voltage battery represents the energy tank. In conjunction, complex algorithms are required to make an estimation of energy still available in the battery. The variety of cells that exist provide different behaviors with respect to the amount of energy being stored, ability to provide this energy in short term for high acceleration, and risk of fire and explosion. Having this in mind, the ability to accurately estimate the energy stored in the battery over the entire vehicle lifetime is a pre-requisite to efficiently and safely use the electric vehicle, reduce battery oversizing and maximize battery lifetime.

INCOBAT is an EU research project which supports the large scale deployment of electric vehicles. The aim of INCOBAT is to provide innovative and cost efficient battery management systems for the accurate control of next generation HV-batteries, and finally support the large scale deployment of electric vehicles. The proposed enhanced systems rely on the following aspects:

Introduction of an automotive multicore computing platform (AURIXTM CPU), as well as smart satellite boards, for increased performance, safety and functional density.
Migration of innovative analysis methods traditionally used in the lab (electro-impedance spectroscopy) to embedded control units.
Combined approach for safety, security and service deterioration analysis. This consistent target identification is then pre-requisite to ensure that the battery to be developed will be at the same time safe (against possible component malfunction), secure (against possible threats) and reliable (against possible degradations).

INCOBAT represents a 100% European value chain for the development of next generation HV battery management systems. This project is part of the 4th EV cluster initiative, which is comprised of the FP7 projects eDAS, iCOMPOSE, Batteries2020 and iMPROVE.
