 PBT -
Primary Battery Testing System |
|
The PBT system is designed specifically for
testing primary batteries. Commonly used functions in
primary battery testing such as constant current
discharge, constant load, and constant power discharge
are independently conducted on each channel of PBT.
Ramp or staircase discharge current control are also
applicable. PBT is capable to perform most of ANSI
(American National Standards Institute) and IEC
(International Electrotechnical Commission) test
standards. The plug & play design of hardware
emphasizes a preventive safety net, system reliability,
easy maintenance, and low cost.
Features
 |
Maximum of 128 I/V channels in one
system/subsystem, each channel has two current
ranges. Independent control for each test
channel. |
|
|
Programmable discharge current
control with Constant, Ramp, or Staircase mode, as
well as constant load or constant power
control. Specified formula function can
generate particular control profiles. |
|
|
Voltage cut-off can be set at any
value in voltage range, but constant voltage control
is not available in PBT. |
|
|
0.1% FSR accuracy on current
control and reading, and 0.1% FSR on voltage reading
and cut-off. |
|
|
Capable to conduct most of ANSI and
IEC test standards, particularly for dry
cells. A set of preset testing schedules is
included in software package. |
|
|
Current rise time between 300
micro-second and 1ms, depending upon current rate
and setting. |
|
|
Online measurement of DC internal
resistance. |
|
|
Auxiliary inputs such as
temperature, and/or voltage are available. |
|
|
Optional Macro-command to extract
and derive required data, as well as to interpolate
data at middle voltage values. It also
summarizes the data over a batch of cells to obtain
maximum, minimum, average, and standard deviation
values. |
|
|
Plug & play module, easy
maintenance, reliable safety-net design. |
|
|
Continuous constant-load discharge. |
|
|
Single-cycle and double-cycle
intermittent discharge. |
|
|
DC internal resistance monitoring. |
