impres™ Energy System Technology
Overview
The Intelligent Motorola Portable Radio Energy System
(impres) energy system demonstrates an optimal energy
system solution, not only for 2-way radios, but the technology
can be applied to a wide variety of portable products.
It is a tri-chemistry (nickel-cadmium, nickel-metal hydride,
lithium-ion), patented technology that was developed by
our expert design team. The primary elements of the system
are an impres compatible battery and an impres compatible
adaptive charger. The system incorporates the following
key features:
Battery data storage in the battery
"Smart" charger with adaptive reconditioning
capability
Structured priority communication protocol used
between the battery and charger
The battery has an expandable memory architecture that serves
as a repository for all "smart" battery data.
Impres compatible chargers are designed to manage charger
and battery data and provide periodic battery "fuel gauge" recalibration.
Impres compatible chargers also perform battery reconditioning:
Automatic adaptive reconditioning by monitoring battery usage
data
Automatic voltage threshold reconditioning
Manual initiation or termination of reconditioning
Automatic reconditioning allows maximum run time without sacrificing
battery life to unnecessary charge/discharge cycles associated
with manual reconditioning.
The impres system provides the following functions:
Record of date of manufacture
Unique battery serial number
Date of battery initial ("smart") use
Periodic battery fuel tank recalibration
Record of battery charge cycles: "smart", approximated,
and recondition
Record of initial and current "fuel tank" size
Battery end-of-service-life indicator
Impres technology can be used to enhance new products by
designing the product to provide:
Capability to read data over the communication bus
Capability to calculate and interpret battery data
Means to display battery data to the user
We are developing impres compatible accessories and peripherals
such as:
Vehicular chargers and adapters
Multi-unit and single unit data displays
PC-based battery management systems and software
System upgrades and feature enhancements such as projected
battery end-of-life
