Suggested testing protocols for the Energy Reference Battery: (Deep discharge app)

1. Motive:

   a.    BCIS 06

   b.    EN 50342-1 Charge Retention

2. Stationary:

   a.    BCIS 06

   b.    EN 50342-1 Charge Retention

Note:

This battery is primarily a “proof of concept” Silicon Joule technology bipolar battery and for internal evaluation only. It is based on Gridtential’s development kit and is not intended to perform like a fully optimized commercially produced battery.

Expected Cycle Life:  > 500 @ C2 100% DoD
Impedance:                  20 milliohms
Energy density:            18.5 wh/kg

For comparison, a “production version” of the Silicon Joule battery will be:

• 2500 cycles at 80% DOD

• 3 - 30 milliohms impedance

• 55 – 60 wh/kg energy density

Reference batteries are part of the Test Bundle provided by the Technology Evaluation Agreement
