Importance of Precision

This plot illustrates the difference between an Arbin battery tester and another leading manufacturer. The two distinct dips in the plot may have been missed using inferior test equipment. 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 to develop high-current high-precision testers, and have implemented this new technology in our MSTAT, LBT and HPT test equipment series. The HPT and MSTAT systems represent our premium product, but LBT is superior to other standard testers on the market.

Measurement precision is more critical for long‐term battery testing and long‐term battery 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

What Affects Tester Precision Arbin Tester Improvements
Resolution of DAC Higher Resolution
Resolution of ADC Improved Software Algorithms
Non-linearity of calibration New Ways of Temperature Management
Short-term drift (temperature) New Patented Shunt Design
Long-term drift (material characteristics) New Method of Time Keeping
Resolution of DAC New Materials

Ready to Build Your Arbin Battery Testing System?

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.

How to evaluate Battery Testing Equipment

Batteries are a critical component of many products, and energy storage plays a very active role in our lives even outside of the research/industry setting. Therefore, selecting the right battery test equipment is an important decision for companies and the individual researchers who are responsible for producing results, whether they are starting small, or at massive scale.

The expert engineers at Arbin have been advancing the benchmark of “state-of-the-art” battery test equipment for over 30 years. We are defined by innovation, from being the first to apply multiple current ranges on a single test channel to more recently being the only company to offer true high-precision testing for high current applications, and supporting “Turbo Mode” with smart battery modules. We continue to learn from our industry partners and work with them on key technology breakthroughs.

The following report shares some of this knowledge using plain terminology and illustrations. Here are five key topics to consider when choosing battery test equipment:

  1. Hardware – Specifications & Quality of Materials
  2. Software – Usability and Features
  3. Data – Logging, Management, and Analysis
  4. Options – Auxiliary Features and Accessories
  5. Support – Product Safety and Support
