To this end, this paper proposes a novel charging and active balancing system based on WPT for lithium-ion battery packs. In the proposed system, the energy required for battery pack charging and balancing is transmitted wirelessly, which can ensure the tightness, consistency and charging safety of the battery pack.
The experimental result of the proposed balancing strategy. According to the balancing strategy proposed in Section 4, the proposed system charged the battery pack within the t 0 time period to increase the SOC of the battery pack from 30 % to 60.04 % (the SOC of the battery pack is defined to be equal to the minimum SOC in a single battery).
In their study, following a multi-module charger, a user-involved methodology with the leader-followers structure is developed to control the charging of a series-connected lithium-ion battery pack. In other words, they are exploiting a nominal model of battery cells.
The terminal voltage of the battery pack and charging current are shown in Fig. 13 (b). The average charging current and charging power were 2.5 A and 63 W, respectively, and the maximum efficiency of the proposed system was 84.24 % in the charging process.
In balancing mode, the proposed system can wirelessly charge any single battery in the battery pack to ensure the electric quantity consistency of the battery pack, but each balancing operation can only charge one single battery, not multiple adjacent single batteries. An N series-connected battery pack is shown in Fig. 7.
In [ 157], a novel battery charging control minimize battery charging costs. This method has the impor- it is model-free. Therefore, it overcomes the limitations of bat- ties inherent in real-world implementations. Further, giv en the the prediction accuracy. Consequently, to minimize the cost of control objective.
