Publisher’s Note

Balance Instructions: 1. When the equalization light is on, the equalization work is turned on, 2. The equalization light is off, the equalization circuit is in sleep state, 3. The equalization light flashes, indicating that the string is dropped, or the circuit is faulty. The two noise covariance matrices are updated at each iteration using the following two equations in real time: 4. Equalization Control Algorithm Oman, H. Making Batteries Last Longer. IEEE Aerosp. Electr. Syst. Mag. 1999, 14, 19–21. [ Google Scholar] The equalizer works independently, with independent wiring, and has nothing to do with the protection board.

[ Google Scholar] [ CrossRef] Figure 4(b) shows an equalization unit EU1-1 in greater detail, including two inductors ( L1 and L2) and four MOSFETs ( S1, S2, S3, and S4). High-layer units are utilized to transfer energy between any two cells, which speeds up the equalization, increases the battery energy usage, and reduces energy loss. The dual inductors replace the conventional single inductor and increase the cell operating time during an equalization cycle. This way, the circuit avoids keeping the battery idle for a long time and increases the equalization speed. The layer number and unit number per layer are determined by equations ( 1) and ( 2), respectively: where m is the number of equalization layers, n is the number of cells in the series-connected battery, [−] represents the Gaussian rounding function, and a is the number of equalization units in layer i. 2.1.
