Improve battery system design with battery simulation models

Batteries are a key technology in the transition to carbon-free mobility. When it comes to designing battery systems for electric products, batteries must meet certain requirements that must still be met after years of operation, in order to avoid jeopardizing the intended business case and damaging companies. TWAICE's simulation models help engineers make the right decisions fast when designing a battery system, leading to reduced risks, improved reliability, and faster time to market.

Why do lithium-ion batteries age, and how to slow it down?

Electric vehicle batteries are costly and sensitive parts, and their performance depends on numerous factors like frequency of charge and discharge, the charging system, driving habits, and external temperature. Until now, it was almost impossible for developers or users of batteries to make any reliable analysis or statement about the current state of the device. However, this information can be now delivered by the digital twin created by TWAICE.

The Power of Signalling

What is the potential impact of Battery Health Reports (BHR) on remarketing success of the battery electric vehicle (BEV)? Besides age and mileage, driver profile has a major impact on how long a battery lasts. In the absence of documentation of how a driver has treated the battery, residual value formation remains below its full potential.

Impedance Research Paper

Continuous impedance monitoring provides significant insights into the aging status of a battery. However, the on-line determination of battery impedance parameter for its low-frequency part is a challenging task. This paper provides an algorithm for its determination, which features a novel approach to quantifying the impedance caused by diffusion processes at low frequencies.
