    This resource gives you insight into various aspects of Lithium-ion Battery (LiB) pack evaluations. It covers vital parameters, including welding resistance, internal resistance, high potential (Hipot) testing, Battery Management System (BMS) assessment, and load testing, all of which are crucial in determining battery performance and health.

    What are module and pack tests?

    Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics. Common performance-based tests include drive-cycles, peak power capability, BMS software validation, and other application-specific characterization

    How does battery testing work?

    An inherent part of battery testing includes charge and discharge tests to measure the battery capacity and the DC internal resistance at different state of charges (SoC). A battery is charged by using a source to put energy into the battery or discharged by using a load to draw energy out. Let's consider a one-time-use battery as an example.

    What are the fundamentals of battery testing?

    Key fundamentals of battery testing include understanding key terms such as state of charge (SOC); the battery management system (BMS) which has important functions including communication, safety and protection; and battery cycling (charge and discharge) which is the core of most tests.
