Ultra High Precision Battery Testing

For battery applications that demand both high power and long-term performance, precision is an essential testing factor. Higher precision assists researchers in quickly identifying battery performance signals, leading to more efficient and accurate long-term forecasts. Arbin’s high-precision battery testing solutions provide precision that can be relied on to move battery innovation forward.

Solutions for Ultra High-Precision Testing Applications

Ultra High-precision battery testing solutions from Arbin Instruments address the following applications:

  • HPC Measurements (Coulombic Efficiency)
  • Electrochemical R&D, Battery, and Supercapacitor Testing
  • Half-Cell Testing and Materials Research
  • Life Cycle Testing

Importance of Precision

This plot illustrates the difference between an Arbin battery tester and another leading manufacturer. The first of the two distinct dips in the plot may have been missed using inferior test equipment. While many companies try to sell the same legacy 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 LBT, MSTAT, and HPS test equipment series. The HPS ultra-high precision 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 at right.

- Arbin ACIM module

Auxiliary Voltage Measurement
Digital or Analog I/O
Battery Holders

A variety of battery holders are available to complement any test lab.  Arbin offers individual cell holders as well as trays & racks which can be used with a higher quantity of cells.

Individual cell holders are available for coincells, cylindrical cells, pouch cells, and a general interface with alligator clips.

Multi-cell Trays are available for coincells, cylindrical cells, pouch cells, and a blank tray interface.  A variety of rack sizes are available to house these cell trays.

Racks
UPS
CANBus

Accelerated Innovation with Ultra High-Precision Test Equipment

Artificially accelerated life cycle testing protocols result in aggressive test patterns and alter battery performance in unrealistic ways. By supporting more realistic calendar-life use profiles, Arbin’s high-precision testing systems (HPS) allow researchers to see the minute trends and nuances in data that are the first signs of battery degradation – without resorting to these flawed, accelerated methods. This approach can screen out less promising materials and shorten battery development time by focusing on precision rather than speed.
