Design Considerations in High Voltage Battery Based Systems
This presentation will provide an in-depth look at the challenges involved with developing rechargeable high voltage / high power lithium based battery packs that are used in applications such as power tools, mobility products and battery back up systems. We will analyze the requirements of the system and battery pack as well as the interactions between them during the charge and discharge phases. Special attention will be given to the safety requirements of these packs. Comparisons will be drawn between the previous generations of battery packs and the new generations of lithium based battery packs and the impact on the charge and discharge technology requirements.

Battery Management Technology
GEM Power LLC has developed a Total Battery Management System (TBMS) that allows the battery to control the charger through continuous and real time data collection. By combining the sciences of batteries and electronics with software analysis and control, this approach to battery charging becomes totally automatic. Battery type, the effect of environmental conditions, charging rate, and termination voltage are automatically determined without interaction from the user. The results of independent Navy testing have shown that the core charging technology can charge batteries four to eight times faster with increased battery life when compared to standard laboratory charging and conditions, and is applicable to any rechargeable battery chemistry.

Design, Testing and Manufacturing of Rechargeable Bipolar Wafer Cell Batteries for Plug-In Hybrid Vehicle Applications
Electro Energy Inc. (EEI) has developed a patented bipolar architecture for batteries. The design is based on flat wafer cells. The cells use conventional materials and offer increased power and energy densities and projected manufacturing cost savings. Electrode thickness is varied for batteries with increased energy or increased power. EEI has developed a demonstration plug-in hybrid electric vehicles PHEV using the Toyota Prius as the test bed. The EEI PHEV utilizes a bipolar nickel metal hydride battery system, consisting of six modules containing 6.0 kWh of energy storage, and gives the vehicle an all-electric range of approximately 20 miles. Data from the road testing of the bipolar NiMH PHEV will be presented, as well as results from subscale bipolar Li-ion testing.

Eliminating Battery Failure - Two New Leading Indicators of Battery Health
In the backup power industry, reliable power is a must. A large and growing installed base of lead acid batteries supply mission critical power to hospitals, banks, mobile telecommunication sites, receiving and transmission utility sites, and countless other industrial and commercial installations. Despite the importance of these mission-critical, backup power systems remaining healthy, in most cases customer testing of their systems does not accurately show battery health. The World Energy Labs' Interrogator ElectroChemical battery analyzer is the only battery testing solution available today for the Energy Storage and Power Conversion industries with the ability to accurately measure both the electrical and chemical state of a battery.
