SIMCAL - Study and modeling of the calendar aging of NiMH and Li-ion batteries embedded in road vehicles.
Overview
Background & policy context:
The use of energy storage systems for the operation of electric and hybrid vehicles still faces several major challenges:
- One thing is certain: The complexity of architectures in their implementation and management requires an approach simulation for dimensioning and optimization. Such an approach, which must be comprehensive, since ESS electrochemistry on the vehicle system and its use is extremely difficult to implement and is little used,
- Uncertainties: The changing nature of the stresses of storage systems and the use of components and innovative architectures induce uncertainty in their modes of aging and life which are currently a major problem.
Objectives:
The project SIMCAL is focused on the study and modeling of the calendar aging of NiMH and Li-ion batteries embedded in road vehicles.
Methodology:
To better exploit the employed experimental means, the project will pursue the twin goals of modeling
SES already completely covered in Simstock and the more prospective study of the aging mechanisms
calendar in the case of newer technologies where these phenomena are poorly known (especially for
Li-Ion batteries for new generations).
