Linear Battery Testing
For High Power Module Applications
Why Does Precision Matter?
Measurement precision is more critical for long-term testing and long-term projections than control accuracy
alone. Most other battery testing systems do not correctly specify their precision and/or have relatively poor
precision, which hinder the conclusions drawn from results data. Important trends and electrochemical
indicators may remain unnoticed; lost in the measurement noise.
Derived from Arbin’s ARPA-E project with Ford Motor Company and Sandia National Lab, our new Precision
series of equipment incorporates technology developed during this time. High precision current and voltage
measurements, and allows for more accurate columbic efficiency, energy efficiency, and dQ/dV calculations
than was previously achievable with a commercially available testing system.
What Affects Tester Precision
■ Resolution of DAC
■ Resolution of ADC
■ Non-linearity of calibration
■ Short-term drift (temperature)
■ Long-term drift (material
properties)
Arbin Tester Improvements
■ Higher Resolution
■ Improved software algorithms
■ New ways of temp. management
■ New patented shunt design
■ New materials
■ New method of time keeping
Product Description
Arbin’s Linear Battery Testing series
commercializes technology
established during a 3-year ARPA-E
project developing ultra-high precision
testing systems. This product consists of
independent potentiostat, galvanostat
channels for testing batteries and other
electrochemical devices, and is
intended to provide an economical,
yet expandable solution for
applications requiring high-precision
measurements and fast data sampling.
All Arbin testing systems come with a
PC preloaded with our MITS 7 and
Data Watcher software for creating
test profiles, real-time data monitoring,
and data plotting and analysis.

ARBIN INSTRUMENTS
Safety Features
All Arbin test stations are designed and manufactured based on industry regulations and arrive CE certified.
The Arbin system includes an array of safety features that protect the user, the devices under test,
and the test station.
■
The system itself is secure internally to protect from unintentional
misuse. The system is equipped with an emergency stop button
and multiple levels of fusing are provided inside the system for
protections at the channel/board and power supply level.
Arbin’s Watchdog circuit monitors the machine’s internal
communication between the PC and onboard microcontrollers
and will stop all tests if there is a failure that poses a risk. A light
tower array is used to visually alert the user to potential
problems and the PC can be
programmed to sound an audible alarm.
■ The user is able to implement safety limits in the software for
current, voltage, total power, as well as temperature or other auxiliary
readings. These values can be programmed to send the system into a
rest state for a period of time, or simply stop the test and disconnect
the charge/discharge circuitry. There are separate limits available for
each test schedule as a whole, and individual steps within the test schedule.
■
A Redundant Safety System can be provided to independently monitor the devices under test, and can
disconnect the device if a safety setting has been exceeded. Safety is the highest priority when testing
high power devices, and Arbin’s Redundant Safety System provides an additional safety system,
independent of the Arbin hardware and software, to ensure a safe testing environment. The system has
the ability to monitor current, voltage, and temperature. If any user-defined safety settings are reached,
the device under test will be disconnected from the Arbin test channel. A hardware interlock can also be
provided with this system to completely power off the Arbin test station.
■
The reliability of testing can be increased even further by adding a
smart UPS to the controlling PC. This will allow tests to automatically
resume after a brief power failure if they are in a safe condition and
permits user intervention in the process. There is provision for the user
to intervene if desired before the channels resume. This is an essential
component for any user with an unreliable power source unless the
entire facility is on backup power.

Current† (A)
Voltage Cycle V
Outputs constant current to the cell or battery at the value
specified. Positive current refers to charge and negative
current refers to discharge.

C-Rate†
DC Internal Resistance
C-Rate is a method for indicating the discharge as well as
the charge current of a battery. It can be expressed as
I=M*C where I=current (A); C=battery capacity; M is the Crate value.
This function applies a 10-pulse train with 1ms pulse width of
the specified magnitude following a constant-current
charge or discharge step.
Rest†

The battery is disconnected from the charge/discharge
circuit but remains connected to the voltage measurement
circuit to enable open-circuit voltage measurement.
Equips the user to control and limit schedule steps according to dynamic mathematical equations in addition to constants or instantaneous channel data.
