Next Generation Battery Management Systems
Purpose and goal
The main goal of the project was to enable high volumes of electrified vehicles by obtaining strategically important knowledge within the battery area. The goal has been acheived and have made VCG a better specifier, developer and purchaser of battery systems. The project will contribute to the successful implementation of VCG´s electrification strategy in the future. Through the company´s already successful sale of PHEV vehicles today, the project has contributed to the FFI Energi och Miljö:s overall objectives.
Results and expected effects
The main results and deliverables are: Strategically important battery knowledge Battery suppliers evaluations Competitors benchmark Design guidelines Commodity buisness plan VCG battery strategies (design, cell, usage, prolong life, cooling, buisness) VCG process for life model and battery usage VCG battery lab Battery test methods Battery models (electrical, thermal, plant, controller, EIS, life, crash) BMS functionality The results from NGBS has gradually been utilized in product development at Volvo Car Group within the project time frame.
Approach and implementation
Battery systems contains a number of different components and functionality that requires knowledge from different disciplines, such as, for example chemistry, mechanical and thermal knowledge. For mastering the battery area, it requires a lot of different competence and within the project; we have set up 10 work package that covers six different areas, system design & optimization, management functionality, models, usage & life, safety and thermal system.
