SOUTHFIELD, MI (FEB 10, 2003) | With heightened interest in hybrid vehicles demonstrated on the part of global manufacturers, First Technology is pleased to announce a safety component for these higher-powered electrical systems. This product takes the form of a battery disconnect device that is the result of an extensive testing and development effort on the part of First Technology in cooperation with OEMs and Tier 1 Suppliers. "Higher voltage electrical systems are a key enabling technology for features that consumers will demand, including hybrid powertrains and enhanced braking systems. Our battery disconnect device provides the manufacturers of hybrids an essential safety element," says Jeff Wood, Chief Operating Officer of First Technology.

With electrical power providing significant driving force, it is easy to recognize that hybrid vehicles will incorporate higher electrical currents than today’s gasoline only vehicles. It is exactly for this reason that First Technology is focusing on safety, providing an easy-to-use remote on/off switch that will help protect in the case of collision, short circuit, electrical overload, or for routine service.

The core of the battery disconnect device is an extremely fast acting bi-stable actuator that draws no power for continuous operation, and requires little power to switch on or off. The device can accept a signal from a collision detection module which controls the air bags and turns off vehicle power after collision, reducing chances of fire or electrical shock. No action is required by the driver. The First Technology battery disconnect device can be set to disconnect the entire vehicle’s power supply or to selectively maintain power to safety and convenience items like hazard flashers, Telematics by OnStar®, power windows and power door locks.

In addition to safety and security, this device also provides service benefits and an opportunity to optimize electrical architecture. Technicians and vehicle owners will have an easy way temporarily to disconnect power for routine service activity. Designers of vehicle electrical architectures will have more freedom in battery placement and cable routing. Not just a product for tomorrow’s vehicles, the battery disconnect device is useful today, as its power circuits are fully backward compatible into today’s 14-volt vehicles.

This low cost, fast acting and highly customizable switch is available from First Technology, a leading worldwide OEM supplier of fuel cutoff switches and similar safety devices for over 30 years. The First Technology battery disconnect device will soon be seen in an upcoming full-size hybrid pick-up truck, and is being promoted for numerous other vehicles.
