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.
A mobile battery with zero initial stored energy and located at bus 1 of the system at the beginning of the time periods is supposed. Power rating of the mobile battery is equal to 750 kW and with 2000 kWh energy capacity. Furthermore, charging and discharging efficiency of the battery are equal to 0.95.
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.
At last but not the least, by using mobile battery storage total energy losses of the network is reduced from 6288 kWh to 5333 kWh which is comparable with respect to the mobility costs. Table 3. Total results of the simulations.
