Estimating the term…
A substrate of a circuit board and a substrate of a charging coil are disposed at a same layer, a first wiring layer and a first coil are disposed at a same layer, and a second wiring layer and a second coil are disposed at a same layer, so that the charging coil and the circuit board form an integrated structure. The first coil and the second coil may be directly electrically connected to a wire on the circuit board, for example, a wire at the first wiring layer of the circuit board or a wire at the second wiring layer of the circuit board. This can shorten a charging path between the charging coil and a load, to reduce a link loss. In addition, a BTB connector can be omitted, to simplify a structure of a charging coil module, and reduce costs of the charging coil module.
A charging coil module, comprising a charging coil and a circuit board, wherein
An electronic device, comprising a load and the charging coil module,
A charging system, comprising an electronic device and a charger, wherein at least one of the electronic device and the charger comprises the charging coil module, and the charger is configured to charge the electronic device;
