View moreTest 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).
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.
Common test methods include time domain by activating the battery with pulses to observe ion-flow in Li-ion, and frequency domain by scanning a battery with multiple frequencies. Advanced rapid-test technologies require complex software with battery-specific parameters and matrices serving as lookup tables.
At a charge efficiency of 99 percent, Li-ion is best suited for digital battery estimation. This helps in BMS design by enabling capacity estimation with coulomb counting. While the readings are instant, occasional calibration is needed to correct the tracking error that occurs with random battery usage.
For a device with integral antennas, an unmodified sample with the integral antennas atached must be supplied to perform those test that require radiated test methods to be used, eg Spurious Emissions. The special test modes that radio compliance requires can be power intensive.
In Europe the Radio Equipment Directive contains receiver test such as: Once you have placed an order, you will be assigned a PM. They will advise you of the next available dates for testing (unless this has been previously agreed).
