* Required Accuracy

Target Assumptions10 year life – 4000 days10% Loss due to Calendar Life losses

Calculations10% / 4000 = 0.0025% loss per day or 25 ppm

Requirement* Usable data must be repeatable to single digit ppm *

* No one is yet claiming that an absolute life can be accurately determined with CE testing. Just estimations and relative differences between similar cells.

Dalhousie / Dr. Dahn Comments

Dalhousie – evaluating ADC/ADT solutionBest of all testing to date!

“The A+D box is giving only 3 ppm noise! This is very decent.", "I will be showing this bar graph to many of my contacts".

Experience – GM Global Battery Lab

The fully integrated “high reliability” third-generation system is not merely a possibility, but is currently deployed at the GM Global Battery Lab in Warren.

According to the lab manager:

“This kind of automation and lab management system is a requirement for our new lab. Despite our years of experience dating back to the EV-1 program this lab would have cost more and certainly not been completed 6 months ahead of schedule.”

Proprietary and Confidential, A&D Technology, Inc.

Slide 26

• 128 Battery Pack and Module Test Channels

• 96 Battery Cell Test Channels– Fully automated (tests, ECU data, equipment, safety)

– Environmental chambers

– 24/7 unattended operation

– Integrated lab data and safety management

– Industry standard and customer specific tests

Scope of Work GM example details

Proprietary and Confidential, A&D Technology, Inc.

Slide 27

Conclusions

This system is becoming the industry standard for advanced battery testing (GM, Magna etc.)

•Reduced Down time = Improved Lab Utilization

•Fewer Resources = Lower Cost (people, equipment, specimens, etc.)

•Reduced Human dependency (writing tests, analysis) = Higher Test accuracy and Reliability

•Better Runtime efficiency = Less Time on test

(24/7 operation with preventive safety systems allows for condensed test time, especially crucial for life cycling)

Conclusions

“This software and hardware will bring our business into the future. This major step forward would not have been successful without the knowledge and capability of A&D Technology”
