Electronic device and battery module

A battery module, comprising:

• a battery component configured to store electrical energy or release the stored electrical energy;
• and
• a charging component, connected to the battery component, being configured to charge the battery component through transmission of a wireless signal with a power supply device;
• the battery module having at least two thicknesses in a stacking direction of the battery component and the charging component,
• wherein the charging component comprises:
• a rectifier subcomponent located at a first end of a first side of the battery component;
• and
• a charging subcomponent located at a second end of the first side of the battery component, the second end being opposite the first end;
• and a spacing being disposed between the charging subcomponent and the rectifier subcomponent, a cross-section of the battery component at a position including the spacing having a first thickness, a cross-section of the battery component at a position other than the spacing having a second thickness, the second thickness being different from the first thickness.

• a charging component, connected to the battery component, being configured to charge the battery component through transmission of a wireless signal with a power supply device, the battery module having at least two thicknesses in a stacking direction of the battery component and the charging component,
• a battery casing having a receiving cavity configured to receive the battery component and the charging component;
• a charging coil located in the receiving cavity, being configured to:
• induce the wireless signal, convert the wireless signal into a charging signal, and charge the battery component based on the charging signal;
• a rectifier subcomponent connected to the wireless charging coil, being located at a different side of the battery component from the wireless charging coil, and being configured to rectify the charging signal;
• and
• a charging subcomponent connected to the rectifier subcomponent, being located at the different side of the battery component from the wireless charging coil, being configured to transmit the rectified charging signal to the battery component to charge the battery component, the rectifier subcomponent and the charging subcomponent being located at opposite ends of the battery component.
