View more6 FAQs about [Automatic calibration of lithium batteries]
What is battery calibration?
Battery calibration involves resetting the battery’s internal circuitry to provide accurate readings of its charge level. Lithium-ion batteries have limited charging cycles before they start losing capacity. As a result, they need to be calibrated periodically to maintain their accuracy and prolong their lifespan.
Why should you calibrate a lithium ion battery?
As they age, lithium-ion batteries can develop a “memory effect” where they think they have less capacity than they do. By calibrating your battery, you reset this memory effect and get accurate readings of its charge level. A calibrated battery can perform at maximum capacity, giving you longer use before recharging.
How often should a battery be calibrated?
For older devices, calibration should be done every 3–6 months, depending on use and battery performance. You can also download apps that monitor your battery’s health and provide alerts when calibration is needed. Calibration ain’t rocket science, but a calibrated battery can make you feel like a master of the universe. Here’s how to do it:
Why do I need to calibrate my battery?
By calibrating your battery, you reset this memory effect and get accurate readings of its charge level. A calibrated battery can perform at maximum capacity, giving you longer use before recharging. It also helps prevent overcharging, which can decrease battery life. Does your device shut down unexpectedly when the battery still shows some charge?
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.
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.
