Case Study

medini analyze Helps LiTHIUM BALANCE Meet the Functional Safety Standards of the Global Automotive Market

“LiTHIUM BALANCE A/S is a small technology company that is competing with established automotive suppliers to develop battery management system (BMS) solutions for electric and hybrid electric vehicles. Because the BMS manages and controls all battery functions — safeguarding against such problems as overheating — it is critical that our solutions meet the highest functional safety standards, including ISO 26262. Unless we meet these standards, we will not be able to supply products to the global automotive market. We rely on Ansys medini analyze to manage and automate the process of certifying our battery management systems. By taking significant time and costs out of the development cycle, medini analyze positions LiTHIUM BALANCE to compete in the global automotive battery market. It is absolutely been critical for the analysis and quantification of our safety goals.”

Introduction

medini analyze helps LiTHIUM BALANCE meet the extremely demanding functional safety standards of the global automotive market — while also reducing development time and costs.

At the heart of today’s electric and hybrid vehicles is a sophisticated battery management system (BMS) that ensures effective and safe charging, energy storage and daily operation. Based in Denmark, LiTHIUM BALANCE is a startup company that has established a track record of innovation in delivering more than 800 customer BMS projects. BMS solutions from LiTHIUM BALANCE are known for their high performance and affordable cost — as well as their uncompromising compliance with the demanding safety standards of the worldwide automotive industry. In order to compete in the global automotive market, LiTHIUM BALANCE leverages the most advanced engineering technologies and best practices, including engineering simulation via Ansys. 

The Challenge

All companies supplying BMS solutions to the world’s automakers must meet stringent functional safety standards, including ISO 26262. By leveraging the power of Ansys medini analyze, engineers at LiTHIUM BALANCE are able to quickly and affordably manage the functional safety verification of their BMS designs. Because medini analyze manages and automates the process of compliance, industry certification is engineered into the company’s BMS solutions from the very earliest stages of design — saving significant development time and costs.
