Summary
The DOE Energy Storage Program funded testing provides an unbiased resource for test information, which can be used at all levels in the decision making process.
Testing support provides MeadWestvaco/NorthStar and Electro Energy Bipolar NiMH Battery manufacturers with timely performance results for advanced carbon formulations and Bipolar NiMH design considerations.
16
Summary
Supercap abuse testing has identified the effects of over-voltage and temperature and the hazardous gases vented from supercaps using acetonitrile. This work is critical for safe design of supercap systems used in utility applications.
Intermediate State of Charge (ISOC) cycling of the SunGel battery used in the ILZRO Peru RAPS system provides detailed charging requirements and performance measurements that can be transferred to the fielded system.
