Battery Testing Solutions

Energy Storage Test System

For mission-critical applications, researchers and manufacturers need to know without a doubt that batteries are charged and will keep a charge. Our Energy Storage Testing instrument (ESTi™), a commercial off-the shelf, PC-based modular battery test solution, offers highly accurate measurements at a fraction of the cost of a custom test system.

This system’s highly intuitive ESTiViewTM drag-and-drop software powers the ESTi platform. You can quickly program charge, discharge, pulse, and ramp parameters to reflect exactly what you need to measure. You can also easily modify parameters based on changing application needs, create custom reporting dashboards, drag-and-drop module tests, and provide meaningful and actionable data from tests.


Key Features

battery test



A growing dependency on batteries requires diagnostics to maintain or predict battery reliability. There were many battery testing methods available, such as voltage reading, Coulomb counting and so on. However, these methods seldom provide full scale accuracy or have long testing periods, becoming a limiting step in battery processing throughput. This created a need for not only accurate but fast testing technologies for energy storage devices with good demonstration of reliability and repeatability.
