TWAICE Unveils New Battery Model Library for Faster and More Flexible Lithium-Ion Battery Development

April 26, 2021 by Stephanie Leonida

TWAICE provides customers with a new battery model library with flexible licensing and a range of validated cell simulation models.

TWAICE provides predictive analytics software for the optimization and development of lithium-ion batteries (LIBs) through the use of digital twins. A digital twin is a real-time, computerized model of a physical object or process. 

The company builds virtual representations of battery models and collects data with control units. This allows for virtual testing and analysis of LIB condition and health. With this information, predictions of battery life can be made and proper management put in place to improve battery longevity. Manufacturers and integrators can optimize their system configuration and validate their battery systems. 

Recently, the Munich-based battery analytics company introduced its new battery model library. The library provides customers with the ability to acquire validated battery cell aging simulation models much more quickly and increases the flexibility of licensing models.

LIBs

LIBs are becoming more widely used as the world moves slowly toward large-scale electrification. This type of rechargeable battery is used in a variety of products and devices because of its high energy density, slow loss of charge when not in use, and favorable energy-to-weight ratio. LIBs can be found in laptops, electric vehicles (EVs), mobile phones, implantable medical devices, and more. 

There are three primary cell formats of LIBs: cylindrical, pouch, and prismatic. TWAICE employs a digital twin that can help customers improve the development and deployment of all of these batteries. TWAICE’s battery model library is a repository of electrical, thermal, and aging cell simulation models. The library helps to promote development by simulating rather than testing battery behavior.

 

Accelerating Battery Development

With the battery model library, cells can be selected or requested by customers. Models are parameterized at TWAICE on-premises testing facilities within three months. This speed can help push forward battery development and speed up the time-to-market. 

TWAICE optimizes testing procedures and uses testing and field data to make this possible. TWAICE aims to provide standardized and validated models to suit a variety of customer applications through its new library. Customers can request model adaptations or extensions of the validity range.

In a news release, TWAICE Co-CEO, Dr. Michael Baumann, commented: “We were overwhelmed by the positive feedback on our cell simulation models and have constantly improved the parametrization processes to deliver high-quality models faster.” Dr. Michael Baumann added: “Customers want a variety of cells and they want them now. We are very happy to have reached the stage where we can offer just that”.

 

Flexible Licensing 

TWAICE’s customers are offered flexible licensing options where customers are billed for the agreed rental period only. For those customers that do not want their cells added to the library, TWAICE makes sure that models are not made available to anyone else, providing the proprietary charge is covered. Customers progressing with their battery development can move on to prototype or series production with in-field data and gain access to TWAICE’s full spectrum of predictive battery analytics processes.
