A variety of standard and customized solutions are available

Arbin offers battery testing systems for basic charge/discharge cycling, and simulating complex real-world applications such as drive profiles, telecomm pulses, or other custom profiles.

Arbin’s Laboratory Battery Testing (LBT) 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 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 & analysis.

Primary Applications:simulation2rdrive-cycle

  • Life Cycle Testing
  • Smulation of real-world test profiles
  • Cranking amp tests
  • R&D of batteries for electric vehicle and grid storage applications
  • Validate 3rd part charger or internal battery management system (BMS) using CANBus or SMBus protocols

importANCE OF PRECISION

This plot illustrates the difference between Arbin and another leading manufacturer.  The two distinct dips in the plot may have been missed using an inferior tester.  While many companies try to sell the same antiquated equipment for over a decade, Arbin has been hard at work improving our designs to meet future industry demands.  We learned a lot during our three year ARPA-E project and have implemented this new technology in our LBTand HPT product series.  The HPT systems represent our premium product, but LBT is superior to all other standard testers on the market.
Please see our  HPT Product Series to learn more.

 

 

 

What Affects Tester Precision
Resolution of DAC
Resolution of ADC
Non-linearity of calibration
Short-term drift (temperature)
Long-term drift (material characteristics)

Arbin Tester Improvements
Higher Resolution
Improved Software Algorithms
New Ways of Temperature Management
New Patented Shunt Design
New Method of Time Keeping
New Materials

 

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 as illustrated above.

 

 

Our hope is that these higher degrees of measurement precision will lead to new discoveries and characterization metrics across the energy storage industry for all organizations, not only those looking at coulombic efficiency as a key indicator.
