Does a smart battery need to be calibrated?
To maintain SoC accuracy, a smart battery requires periodic calibration. If calibration is not available, the device manufacturer advises to occasionally apply a full discharge in the device. This resets the discharge flag, followed by the charge flag when full charge as illustrated in Figure 1.
How to calibrate an EV battery without tools?
Knowing these characteristics, an EV battery can be calibrated without tools by following this procedure: Apply a deep discharge by driving the extra mile. Be mindful when at low charge state as the vehicle’s indicated range can be off by as much as 30%. Extreme low SoC is noticed when acceleration becomes sluggish.
How does battery capacity estimation work?
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.
How can OCV-SoC curve calibration be improved?
OCV-SoC curve calibration by redefining max–min bounds is proposed for better SoC estimation. SoC estimation is further improved using ASRUKF algorithm with parameters identified online. OCV-SoC curve calibration by redefining max–min bounds is able to result in an overall better SoC estimation performance.
How to calibrate a smart battery with impedance tracking?
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.
What is lithium-ion battery SoC estimation?
Lithium-ion battery SoC estimation is one of the key functions of BMS. The model-based SoC estimation methods can follow actual SoC value in a precise and adaptive way. OCV-SoC curve is essential in model-based SoC estimation methods.
