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.
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.
Lithium-ion batteries are not limited to serving as an EV’s power source. The technique of fully charging and discharging batteries during each cycle is referred to as deep-cycle charging. 28 This method is preferable as it enables the battery to function optimally and consistently across several charge and discharge cycles.
Additionally, adopting a power control technique becomes essential to achieve both constant current (CC) and constant voltage (CV) modes during battery charging. Integrating CC and CV modes is crucial for efficiently charging lithium-ion batteries, ensuring prolonged lifespan and optimal capacity utilization.
The pulse charging of the Li-ion battery on the second side is accomplished through phase-shifted control of the primary side high-frequency inverter. The control loops for pulse charging must be developed using the IPT transfer functions, according to the implementation technique.
For example, to increase the charging speed, the lithium-ion battery should be charged at its optimal frequency, which corresponds to minimized ac impedance of the battery. The lithium-ion battery shall be charged in the optimal working period to increase the charging efficiency.
