Calibration of a smart battery with Impedance Tracking needs rest periods, a service that is best done with a battery analyzer. This so-called formal calibration also resets the Max Error, a function that a full cycle alone will not provide. Testing batteries on an analyzer also displays the real usable capacity with Ri to verify SoH.
In time the line blurs again and a recalibration is needed. Device manufacturers advise to calibrate smart batteries every three months or after 40 partial discharges. Calibration error is recorded by the Max Error metric. A number 1 reflects a well-calibrated battery; higher figures indicate the need for service.
Here we demonstrate the development of novel miniature electronic devices for incorporation in-situ at a cell-level during manufacture. This approach enables local cell-to-cell and cell-to-BMS data communication of sensor data without the need for additional wiring infostructure within a battery module assembly.
Capacity estimation by Impedance Tracking requires assessing the remaining charge (old fill) before charge. The smart battery does this by measuring the open circuit voltage (OCV), a value that is compared against a reference curve matching the battery chemistry.
Calibration error is recorded by the Max Error metric. A number 1 reflects a well-calibrated battery; higher figures indicate the need for service. A charge-discharge-charge calibration cycle as shown in Figure 1 does not correct loss of capacity.
The LiFePO (LFP) in the lithium battery family has a very flat midrange curve, but the more popular NMC has a measurable mid-charge tilt. Knowing these characteristics, an EV battery can be calibrated without tools by following this procedure: Apply a deep discharge by driving the extra mile.
