AI Customer ServiceFirstly, the experiment with traditional method that limiting the circulating current to zero is conducted. Then, the proposed circulating current is injected. The amplitude and phase of the injected circulating current are 1.6 and 0 respectively. The parameters of the experimental prototype are shown in Table 1.
Therefore, an additional charge throughput reduction method has been proposed for the MMC-BESS based on the second-order circulating current injection. Firstly, the principle of the MMC-BESS is introduced. Then, the additional charge throughput is analyzed by the instantaneous power fluctuation in the arms of the MMC-BESS.
As we shift toward electrification, the number of spent batteries will increase dramatically. The current recycling process involves dismantling the batteries to recover valuable raw materials and resynthesizing them. However, this process is time consuming, costly, and energy intensive.
In [ 9 ], a certain second-order circulating current is injected in order to reduce the capital voltage ripper in MMC-HVDC. It has aroused widespread attention to the second order current injection method in the HVDC field.
The principle of reducing capital voltage ripper can be similarly used for the reduction of charge throughput. To solve the above issue, an additional charge throughput reduction method is proposed in this paper. The rest of this paper is arranged as follows. In Chap. 2, the topology and principle of the MMC-BESS are presented.
The capacity-recovery effect was confirmed when the cells with high-density electrodes were treated with CV at 4.0 V (Figure 4 Diii), indicating that CV treatment is effective for high-energy-density batteries with high-density electrodes.
