Arbin offers ultra-high precision charge/discharge testing systems for meaningful coulombic efficiency testing on cells up to 200A.  Low current HPT systems are also available.

Arbin Instruments, Ford Motor Company and Sandia National Lab partnered together on anARPA-E project beginning in 2012 to develop a high-precision, high-power battery tester.  This new “HPT” system allows users to more clearly see degradation mechanisms on a full-scale (high capacity) cell under real-world conditions.  The project goal was to develop a testing system capable of 50ppm coulombic efficiency precision at up to 200A.  This project concluded in 2015 with Arbin’s successful commercialization of the new HPT product series.

HPT systems have been used by leading industry partners since 2014 during the ARPA-E project evaluation period, but only became available to the general public in 2016.  What sets the Arbin HPT apart from other high-precision testers is the power level.  Achieving 50ppm CE precision above ~2A required a tremendous amount of R&D and technological advancement.  Arbin offers HPT systems at 100mA, 1A, 5A, 50A, and 200A. 

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.
