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

Impres compatible batteries perform "smart" battery
functions:
- Monitor elapsed time
- Record charge & discharge current
- Monitor battery voltage and temperature
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
