Tesla Model S Battery Capacity
On average the batteries have 92% remaining at 150,000 miles.
If the linear behavior would continue, then the ‘lifetime’ (still 80% capacity left) would be
500,000 miles!

Challenge to the Test Industry
What is the IDEAL production burn-in / reliability test solution
100% certainty of devices receiving valid burn in with per device traceability
Devices are assured that they are not experiencing higher stress through inaccurate voltages, currents, or thermal temperatures
Per device temperature, current, and power monitoring
Parametric and functional data for burn-in effectiveness on every device
Full Automation – remove human error and handling
Massive Parallelism to achieve cost points to allow 100% infant mortality testing
