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.

On-board circuitry

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. |

An Aved Electronics custom configured pack utilizing
top name components.
|
|
| As
a master distributor for top brand manufacturers like Saft
America, Renata, Eveready, Duracell and Rayovac, Aved
Electronics has the ability to combine the best technology
at the lowest cost. Understanding the latest developments
in anode, cathode, and electrolyte technology, we can help
you choose the best primary solution for your portable applications,
and then create a custom configured pack to meet those needs. |

A Raid controller
with minimal board space needs a high temperature solution.

A lithium ion
battery pack configured with prismatic cells.
|
|
| The
key to this challenge was not only to design a low profile
battery pack, but to somehow save as much component real
estate as possible. The first step in reducing the size
was going from 4 NiMH cells to 2 Lithium Ion prismatic cells.
This both cut the size in half and also answered any concerns
about the high temperature of the application. Next, Aved Electronics
created a unique bracket designed to raise the entire battery
pack up high enough to allow the board to be fully populated
with components underneath it, but low enough not to interfere
with other height restrictions.

A mobile medical intravenous
unit in need of a highly reliable and durable power solution.

A snap on battery
pack with excellent portability, long run time, and ease
of user handling and replacement.
|
|
| A
Saft VRE-C 2.3AH NiCad cell was chosen because it allowed
the battery pack to perform to 150% of the expected run
time. The pack also needed to be durable enough to withstand
a two meter drop shock. A cylindrical design using rigid
PVC plastics was developed to protect the battery. The result
was an electrically isolated tube capable of withstanding
300 ft/lbs. of pressure that could be snapped into place
quickly and easily. Internally, the battery assembly needed
to be shock resistant. Aved Electronics devised a cell interconnect
method utilizing a combination of pure nickel straps, nickel-plated
steel rings, rivets, and end caps. Vibration was controlled
through specifically designed rubber gaskets and Mylar spacers.
Utilizing the latest advances in resistance welding, Aved Electronics
completed the design of a rechargeable battery pack that
would perform to the high standards required. |

An ultrasonically
welded Nickel Metal Hydride battery pack designed to snap
on to the back of the device.
|
|
| Six
NiMH cells best suited the power requirements of the application
and were encapsulated in a plastic enclosure, then ultrasonically
welded. The enclosure was designed to snap on to the back
of the device, allowing the end user easy access to replacing
the pack. This also allowed for a second battery pack to
be sold with the unit or as an after market item. By placing
the battery power external to the device, board real estate
is saved, correct polarization is assured and the possibility
of failures due to wiring or connectorization are virtually
eliminated. Aved Electronics can help you design a “snap-on”
battery powered solution for your application with unlimited
possibilities in configuration, shape, size, chemistry,
voltage and capacity. |
