A newly developed powertrain-integrated battery sizing tool is demonstrated here to showcase its capabilities along with pros and cons of battery hybridization. 

Our hybrid solution combines two cell chemistries — high energy and high power — and optimizes them to deliver the perfect balance of performance tailored to your required profile. More information about hybrid batteries technology here. 

This optimization aims to provide a hybrid battery solution with : 

• High peak power density
• Cost reduction (up to 50%)
• Weight reduction (up to 25%) 

The tool allows using the powertrain model of an electric vehicle (car, truck, boats, …) to compute a battery load profile from a velocity profile. For other application (e.g. stationary energy storage systems), the tool allows direct uploading of a custom battery load profile. In both case, this battery load profile is then analyzed to compare between monotype and hybrid battery configurations, the optimal choice of battery chemistry, the optimal layout of the battery system (series-parallel arrangement), the optimal power-splitting strategy, etc. The powertrain model can then ben updated with the sized battery system, allowing to test the vehicle model with a new velocity profile scenario.

The main benefits of the tool are therefore : 

• Evaluating the battery load profile of your application when:
  • No measurements are available
  • For new/unknown velocity profile scenario
  • The vehicle is not yet electrified (estimation based on a new e‑powertrain model)
• Finding optimal battery configuration, chemistry selection, sizing and layout
• Allowing verification of the sized battery for additional velocity profile scenarios
