Free QuoteThe method undergoes a real-world electric vehicle testing with 276 cells. The limited charging performance of lithium-ion battery (LIB) packs has hindered the widespread adoption of electric vehicles (EVs), due to the complex arrangement of numerous cells in parallel or series within the packs.
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.
In practical applications, lithium-ion batteries are usually connected in series to build a battery pack to satisfy the power and voltage demands of devices. However, the internal resistance, capacity, voltage and other parameters of each lithium-ion battery may be inconsistent due to the manufacturing process .
Methodology Leveraging the derived battery pack model, we introduce a refined online fast charging framework that mitigates lithium deposition. Fig. 3 outlines the architecture and interplay of the algorithm, showcasing an integration of two essential close-loop algorithms: the state observer and the current controller.
A novel charging and active balancing system based on wireless power transfer for lithium-ion battery packs is presented. The charging and balancing power is adjusted according to the voltage level of the primary side of the DC/DC converter.
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.
