Low-energy-consumption high-frequency wireless charging system for lithium battery

1:

• A low-energy-consumption high-frequency wireless charging system for a lithium battery, which comprises:
• a power-supply module;
• a first resonant unit directly connected in series with the power-supply module;
• a resonance-tuning module located at one side of and electrically connected to the first resonant unit, wherein the resonance-tuning module comprises a second resonant unit and a first shunt unit electrically connected with the second resonant unit;
• a second shunt unit electrically connected with the resonance-tuning module, wherein one end of the second shunt unit is electrically connected with the first shunt unit for current reflow;
• a rectifier module located at one side of and electrically connected to the first shunt unit for adjusting the current flow direction;
• a third resonant unit, wherein the third resonant unit is connected in parallel with the rectifier module, and is configured to control the frequency of the rectifier module;
• a voltage stabilizing module, wherein one end of the voltage stabilizing module is electrically connected with the rectifier module;
• a power-storage element connected in parallel with the voltage stabilizing module;
• and
• a grounding portion located at one side of and electrically connected to the power-storage element.
