A rechargeable energy storage apparatus (10), a wireless charging system, and an electric vehicle are provided. The energy storage apparatus (10) includes a power receiving coil (11), an inverter-rectifier module (12), a control module (13), a battery cell module (14), and a heat dissipation plate (15). The inverter-rectifier module (13) is separately connected to the power receiving coil (11), the control module (13), and the battery cell module (14), the battery cell module (14) is connected to the control module (13), and the power receiving coil (11) is disposed on a lower side of the heat dissipation plate (15). The power receiving coil (11) is configured to generate an alternating current when receiving an alternating magnetic field generated by a transmitting coil (21) located on the ground. The control module (13) is configured to control the inverter-rectifier module (12) to convert the alternating current output by the power receiving coil (11) into a direct current and output the direct current to the battery cell module (14); and is further configured to control the inverter-rectifier module (12) to convert the direct current output by the battery cell module (14) into an alternating current, to drive an electric motor to work. The energy storage apparatus (10) integrates an inverter and a rectifier into one according to electrical principles, so that a quantity of components of the energy storage apparatus (10) is reduced, and manufacturing costs are reduced. The control module (13) in the energy storage apparatus (10) integrates functions of three types of controllers, and this improves overall control efficiency of the energy storage apparatus (10).
