Lithium-carbon-liquid electrolyte battery system for electric vehicles: battery module and system development project

Objective



Objectives

This three year project is dedicated to the study and the manufacturing of lithium-carbon battery system prototypes and battery modules prototypes.
The following performance characteristics are targeted at battery system level:
energy content : 30 kWh
weight : 250 kg max
volume : 150 dm3 max
power capability : 60 kW
number of charge / discharge cycles : 600 minimum

Technical Approach

The two main contractors, SAFT and VARTA, will use electrochemistry previously studied and will develop together a modular design for a battery system with :
standard battery module
battery thermal management system
electronic battery management unit

Expected Achievements and Exploitation

The Lithium-Carbon battery studied will give to the car of tomorrow an autonomy in the range of 200-300 km.

The main achievements of this project will be :
a battery system modular design which meets specifications agreed with car makers,
the development of an electrochemical battery module with standard sizes. It includes a plastic casing study for the module.
the thermal management system (TMS) study; the TMS, based on water/glycol cooling and pre-heating system will be compatible with all types of vehicles.
the study of an electronic control system (ECS) for the battery with a standard interface, between the battery management unit and the vehicle management unit; this ECS provides battery state of change indication and insures battery safety and cycle life.
tests on battery modules and battery systems.
