Access the full potential of battery simulations

Our coupled electric-thermal-aging models support engineers to develop the ideal battery for any use case quickly. Three different model types are provided, ranging from models based on our internal database to ones based on testing data, meaning engineers can leverage these models throughout all stages of battery system development. Combined with support from TWAICE battery experts, these models are the ideal solution for bringing battery simulations to the next level.

Base Model: This chemistry-specific cell model leverages data from our extensive battery database to provide a model for use cases where the manufacturer or the exact cell is not yet known.

Customized Base Model: This model combines the base model with cell-specific data from the manufacturer or your own tests. You can leverage available data & benefit from a more realistic model.

Premium Model: In addition to the other models, measurements conducted at TWAICE's testing facilities are used to ensure highest accuracy and cutting-edge features including modeling of OCV aging, degradation modes, and swelling force are incorporated.

1
Move to virtual development
more info

Our virtual Model Library puts hundreds of years of collective battery expertise at your finger tips. We did the heavy lifting for you. Select the battery model that meets your application requirements through faster simulation, comparing, & testing.

2
Implement end-to-end flexibility
more info

Don’t miss your chance to lead the market by spending too much time testing. By decoupling development processes from the costly physical battery testing infrastructure, you can now test, compare, fail, recover, & change your mind, all at speed.

3
Simplify the process
more info

Battery development is resource hungry—consuming time, demanding more engineers, more hardware for testing, and more money to fund it. We change all that. Our easy to use battery simulation models and intuitive UX & UI simplify cell selection and battery design.

4
Remove risk from decision-making
more info

To do things faster you need to identify and eliminate risk. Get a clear and reliable lifetime view of battery electrical, thermal, and aging behavior under selected conditions. Avoid endless debate and decision hesitancy by removing guesswork, pitfalls, and uncertainty.

Challenges

  • Different cells suit different applications
  • The battery design must ensure safe operation over it’s entire lifetime
  • Difficult assessment of different use case impact of performance over lifetime

Solution

Avoid the cost of oversizing or compromising on performance over lifetime. Identify the optimum number of cells and what the right configuration is needed to meet the power requirements of the application. Simulate different use cases and designs to strike the balance between desired performance and optimal costs
