An apparatus and a system for balancing energy in a battery pack are provided, to implement balanced energy distribution among individual batteries in a battery pack, so as to avoid problems of a complex control structure and high resource overheads in using a prior-art solution of implementing balanced energy distribution among the individual batteries in the battery pack. The apparatus includes: a transmitting coil, configured to transmit an electromagnetic wave generated by an input first alternating current to multiple receiving coils; the multiple receiving coils, where parameter values of all receiving coils of the multiple receiving coils are the same, all the receiving coils are coupled to the transmitting coil at a same coupling strength, and each receiving coil is configured to receive the electromagnetic wave transmitted by the transmitting coil, and generate and output a second alternating current according to the electromagnetic wave; and multiple rectifiers, where the multiple rectifiers are connected to the multiple receiving coils in a one-to-one correspondence, and each of the multiple rectifiers is configured to convert the input second alternating current into a direct current, and output the direct current to one individual battery in the battery pack, where the multiple rectifiers and multiple individual batteries in the battery pack are in a one-to-one correspondence.
