This handbook provides full details on the electrical measurements of LiB packs. It explores key parameters such as welding resistance, internal resistance, Hipot test, BMS evaluation, and load testing — and their significance in assessing battery performance and health.
At the heart of testing battery cells, modules and packs are the levels of voltage and current. Temperature and pressure are increasingly important conditions to test at the pack level, while improving the underlying accuracy of the fundamental measurements is naturally a key trend.
You are here: Home / Blog / PEVs / How To Test A Battery's Capacity Testing a battery’s capacity is one of the best ways to determine the health of a battery cell. indicator of a battery. To test the capacity of a battery cell, you have to fully charge and fully discharge the cell while precisely measuring the energy in at least one direction.
A battery’s capacity can be estimated relatively accurately using a set of measurements and some complex math, but the most simple way to measure a battery’s capacity is to measure the power going into or out of the cell. Power going into the cell would be charge testing and power coming out of the cell would be considered discharge testing.
Well-developed battery test technologies must recognize all battery conditions and provide reliable results, even if the charge is low. This is a demanding request as a good battery that is only partially charged behaves in a similar way to a faded pack that is fully charged.
The system uses the Scienlab battery test equipment to provide precise measurement results, coupled with Keysight’s PathWave Lab Operation software. This manages the planning and execution of test procedures including schedule definition, management, control and monitoring of the battery test systems and device under test.
That creates a significant test challenge. New test techniques, modular test systems and techniques for modelling the battery performance are all helping to reduce the test time of battery packs. This is leading to calls for new standards on how to test effectively and quickly.

A battery tester is an electronic device intended for testing the state of an electric battery, going from a simple device for testing the charge actually present in the cells and/or its voltage output, to a more comprehensive testing of the battery''s condition, namely its capacity for accumulating charge and any possible flaws affecting the battery''s performance and security.
Battery testers can measure a battery''s capacity, voltage, internal resistance, and temperature, among other things. These instruments can also discharge checks. They can indicate how long a battery can run before it needs to be recharged.
Battery Lab B is a large battery R&D validation lab that requires testing battery packs with multiple dimensions that range widely in voltage and power. The packs are in different areas and labs within the facility as well as remote facilities. This requires reconfiguring the cyclers to increase and decrease the power levels in just a matter of days. The types of testing …
