Free QuoteTo 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.
Battery calibration is recommended once or twice a year and when buying a used EV. Batteries in Energy Storage Systems (ESS) share similarities with the EV battery in that the battery system contains modules of serial and parallel-connected cells managed by a BMS. Most ESS's are monitored by observing cell voltage, load current and temperature.
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.
It can be found that the SOC absolute errors of two lithium-ion batteries can be limited in a narrow SOC error band of 0.1%, which suggests that the mean value can be considered as the SOC calibration point to correct the initial SOC value.
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.
A data-driven coulomb counting method is proposed to estimate state of charge (SOC) of lithium-ion battery. The incremental capacity analysis method without filtering process is applied to calibrate the initial SOC value. The Gaussian process regression (GPR) method is used to calibrate the actual capacity.
