Abstract

Disclosed herein is a system and method for selecting a battery for a particular application, for example, batteries used in portable electronics, electric vehicles, satellites, etc. The method uses an end-to-end differentiable modeling approach that allows the selection of batteries directly from the parameters of the battery and a specification of the particular application for which the batteries are being selected.

First claim

1 . A method of specifying a battery for an application comprising:
deriving one or more battery latent spaces describing characteristics of one or more batteries; deriving an application latent space describing requirements of the application; and choosing a best fit between the one or more batteries and the application based on a comparison of the battery latent spaces and the application latent space.

2 . The method of claim 1 , wherein the one or more battery latent spaces are derived from a vector representations of one or more battery specifications.

3 . The method of claim 2 wherein the battery latent spaces are derived using an auto encoding network trained to create the battery latent spaces of the one or more batteries.

4 . The method of claim 3 wherein the application latent space is derived from a vector representation of an application specification.

5 . The method of claim 4 wherein the application latent space is derived using an auto network trained to create the application latent space.

6 . The method of claim 1 wherein the step of choosing the best fit between the one or more batteries and the application comprises:
submitting the one or more battery latent spaces and the latent space of the application to a differentiable performance model to determine the suitability of each battery for the application.

7 . The method of claim 6 wherein the differentiable performance model outputs an indication of the suitability of the battery for the application.

8 . The method of claim 7 wherein the indication is a score and furthermore wherein the battery selected for the application is a battery having the highest score.

9 . The method of claim 6 wherein the differentiable performance model comprises a physics-based model.

10 . The method of claim 6 wherein the differentiable performance model comprises a data-driven model.

11 . The method of claim 6 when the differentiable performance model comprises a fusion of a physics-based model and a data-driven model in a differentiable programming framework.

12 . The method of claim 6 wherein the differentiable performance model is a trained neural network or a set of universal and partial differential equations.

13 . A system comprising:
a processor: software, executing on the processor, the software causing the system to perform the functions of:
deriving one or more battery latent spaces describing characteristics of one or more batteries;
deriving an application latent space describing requirements of the application; and
choosing a best fit between the one or more batteries and the application based on a comparison of the one or more battery latent spaces and the application latent space.

14 . The system of claim 13 wherein the one or more battery latent spaces are derived from a vector representation of one or more battery specifications and further wherein the application latent space is derived from a vector representation of an application specification.

15 . The system of claim 14 wherein the one or more battery latent spaces are derived using an autoencoding network trained to create the one or more battery latent spaces and further wherein the application latent space is derived using an autoencoding network trained to create the application latent space.

16 . The system of claim 12 wherein the software further causes the system to:
choose the best fit between the one or more batteries by submitting the battery latent space of each battery and the latent space of the application to a differentiable performance model to determine the suitability of each battery for the application.

17 . The system of claim 16 wherein the differentiable performance model outputs an indication of the suitability of the battery for the particular application.

18 . The system of claim 17 wherein the indication is a score and furthermore wherein the battery selected for the particular application is a battery having the highest score.

19 . The system of claim 16 wherein the differentiable performance model comprises a physics-based model, a data-driven model or a fusion of a physics-based model and a data-driven model.

20 . The system of claim 19 wherein the differentiable performance model is a trained neural network or a set of universal and partial differential equations.
