Test methods range from taking a voltage reading, to measuring the internal resistance by a pulse or AC impedance method, to coulomb counting, and to taking a snapshot of the chemical battery with Electrochemical Impedance Spectroscopy (EIS).
Specialized test, which at designing stage, a battery may be subjected to, includes Hybrid Power Pulse Characterization (HPPC) test for dynamic performance characterization of energy and power capability of each electrode. Mechanical test for verifying dimensions and stress handling capability.
It is widely used by European automotive manufacturers to test and validate lithium-ion batteries and powered components. Safe EV battery test methods are critically important as advancements in technology produce higher energy densities in lithium-ion batteries.
But this test takes too much time. For example, a 100 Ah battery discharging at 4 Amps will take 25 hours to pass the test. Capacity test also includes usage of hydrometer and thermometer to calculate specific-gravity (relative-density) of electrolyte to determine Depth-of-Discharge.
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.
Environmental test chambers provide the means to understand and implement these enhancements while bolstering consumer confidence. EV batteries are exposed to extreme environmental conditions like heat, cold, vibration, and corrosion in battery test chambers to assess real-world conditions and validation.
