Miniature Battery Impedance Test Equipment

DESCRIPTION

The Miniature Battery Impedance Test Equipment, MBITE,

is designed and ideally suited to determine the health of

flooded and sealed lead-acid and Ni-Cd batteries in

telecomm, RR signal and communications, substation,

process control and switchgear, emergency lighting

systems, smaller UPSs, and more. An additional

application is to measure impedance of batteries at the

end of the production line in battery manufacturing plants.

The MBITE is a lightweight, easy-to-use battery tester that

incorporates advanced features for enhanced capabilities

to provide fast, reliable results to determine what further

action may be required to ensure adequate system back-

up time. After all, measuring batteries is not for the

battery but for the equipment the battery is supporting

whether to ensure revenue streams or to support critical

plant equipment such as oil priming pumps.

In addition to measuring battery impedance and

interconnection resistance, the MBITE also measures

individual dc terminal voltages. Furthermore, since

impedance does not stress the battery, terminal voltages

may be used when they need to be documented. All

three parameters can be stored (up to 1000 lines of

readings) on-board for immediate review at the test site

on the large 31⁄2 digit LCD or from the built-in printer.

The stored data also can be downloaded via the RS-232

connector to a PC using “AVOLink” download software or

other conventional communications packages to

spreadsheet applications for further data interpretation.

The Battery Analysis Report (see Figure 1) prints out cell

number, battery impedance, interconnection resistance,

cell dc voltage, date and time at which cell impedance is

recorded, total test current, and cell impedance summary

including graphical analysis. The printed header has space

to record user, location and cell IDs using the Bar Code

Wand listed in Optional

Accessories.

Unlike load cycle testing,

which involves substantial

downtime and performed

periodically, the MBITE

requires no battery discharge.

With a test time of less than

30 seconds per cell, it

measures internal cell

impedance, dc terminal

voltage and intercell

connection resistance without

taking batteries off-line. The

MBITE, like the original BITE,

is used to find weak cells due

to sulphation, post-seal

corrosion, and poor top lead

and intercell connections.

The test results, along with

user-supplied information

such as ambient temperature

and system ac ripple current,

will provide sufficient

information to evaluate the

overall battery system.
