Batteries

A European instrument manufacturer is forced to provide NiMH pack replacements for NiCad packs already used in instruments in the field, due to environmental regulations.

The Problem:
A European instrument manufacturer is forced to provide NiMH pack replacements for NiCad packs already used in instruments in the field, due to environmental regulations.

The Solution:
On-board circuitry in the new battery pack allows the customer to continue using the old unit without additional modification.

European environmental standards no longer tolerate the use of cadmium found in NiCad batteries. Aved Electronics engineered a retrofit solution for an audiological instrument manufacturer which used NiMH technology to replace existing NiCad packs. On-board circuitry was designed to regulate the input charging voltage, current, and duration to protect the battery pack from heat-related failure. Tight space requirements demanded a unique use of embedded molding in the placement of sensor components within the structure of the existing design. Aved Electronics was able to provide a successful solution that was transparent to the OEM's customer base.
