The invention is applicable to the field of charging, and provides a charging system and a charging method. The charging system comprises first equipment with a magnetic medium, and second equipment which can sense flux change quantity and convert the flux change quantity into electric energy, wherein the second equipment is provided with a charging protection circuit for limiting the converted electric energy, and a charging interface connected with to-be-charged equipment; and the charging protection circuit is connected with the charging interface. Due to change of a relative position between the first equipment and the second equipment, the second equipment can generate the flux change quantity and convert the flux change quantity into the electric energy; and the charging protection circuit is connected with the charging interface, so that the converted electric energy can be transmitted to the to-be-charged equipment by the charging interface. According to the charging system and the charging method, the charging endurance power is not influenced by limited battery capacity, so that true and persistent charging endurance is achieved.
