Online Battery Simulators


Welcome to the interactive battery simulation environment for performing battery performance predictions and computer-aided design over the Internet.

The battery simulation(BS) environment for Members Only fully encrypts all submittals to ensure the confidentiality of your design parameters, electrochemical data, and application ranges. To log in, you'll need a password that can be obtained from Dr.Wang

Description

This Web page intends to provide on-line simulation capabilities of predicting battery behavior during discharge, rest, charge, and cycles, based on first principles electrochemical models.
Virtual battery simulators complement the traditional testing method such as this, so as to provide a cost-effective, concurrent engineering approach to battery design, manufacturing, and application.
The mathematical models and numerical procedures used to build the present simulation codes are elaborated in Code Development.
These codes have been experimentally validated to a maximum extent possible; see Code Validation. New experimental data are invited to further validate and improve the current codes.
Potential applications of battery simulators include:
 
 

 

1. Design, scale-up and optimize battery cells and packs by Battery Manufacturers for various consumer applications and/or electric vehicles;

 

2. Perform what-if studies on certain types of batteries (e.g. Aerospace Batteries) by Federal Agencies and National Laboratories;

 

3. Generate dynamic performance data by Battery Users for applications such as design of uninterruptible power supplies (UPS), power storage systems of electric vehicles, etc.
     Some examples of the utility of battery simulators are given in Code Applications .
The simulators provided in the Online Simulation section are Web-based, online, and real-time (many times better than real-time), thus offering the following advantages for academia, national laboratories and industry:
 
 

 

1.  No hardware is required since codes run on our server.

 

2. No software needs to be installed, thus eliminating code compatibility, maintenance and training problems.

 

3. Communication and exchange of simulation results between inter-departments are made easy through the Internet.

 

4. Accessible 24 hours a day, 7 days a week.

 

5. Each customer can order a customized simulator and associated I/O data format which can then be used exclusively by the customer through a selected password limiting the access to it.
 

Code Development

Mathematical Models feature simultaneous incorporation of the following fundamental physiochemical phenomena:

Computational Fluid Dynamics (CFD) techniques are used to numerically solve
the large set of coupled model equations. Unique features of CFD techniques
are:

Model Output Includes:

All the output are functions of time and/or space in a battery cell.

Present family of CFD Battery Simulators:
