ZPower Selects Texas Instruments For First Battery Gas Gauge Solution For Silver Zinc Batteries

January 15, 2008 by Jeff Shepard

ZPower, Inc. announced that it has chosen Texas Instruments (TI) as the company’s first notebook battery gas gauge solution for silver zinc batteries. Based on the TI’s bq2084 battery management platform, the new solution will be part of all ZPower batteries as ZPower prepares for high volume production in mid-2008.

The silver-zinc notebook battery gas gauge solution performs the following: monitors and controls the charge and discharge of the silver-zinc battery; monitors the state of the charge of the battery; provides battery protection from fault conditions; and communicates via SMBus with the notebook computer the status of the battery.

"Texas Instruments is a market leader in notebook battery monitoring solutions," said Dr. Ross Dueber, President of ZPower, Inc. "As ZPower has worked diligently to advance the chemistry of batteries, Texas Instruments has done the same with battery monitoring solutions. Texas Instruments provides us with the best opportunity for compatibility with a wide range of OEMs and makes our battery an even more attractive power source for our customers."

This first notebook battery gas gauge is the initial step toward the development of gas gauge solutions for other mobile applications such as cell phones. ZPower will use TI when developing those solutions as well.

"Texas Instruments is very pleased to have been chosen as the development platform for a silver-zinc battery monitoring solution," said Garry Elder, Systems Engineering Manager of Battery Monitoring Solutions at Texas Instruments. "We’re proud to play a role in the development of this innovative, new power source for mobile electronics."

ZPower batteries are said to offer up to 40% more run time than traditional lithium-ion batteries. Additionally, ZPower™ batteries are said to offer an inherently safe technology which features a water-based chemistry that is not flammable. The battery contains no lithium or flammable liquids and is therefore said to be free from the problems of thermal runaway, fire and danger of explosion.

ZPower™ batteries also offer consumers an environmentally friendly alternative. Over 90% of the primary elements used to produce the batteries can be recycled and re-used. The raw materials recovered in the recycling process of silver-zinc batteries are the same quality as those that went into the creation of the battery.
