The charging system comprises a primary charging unit provided outside a gas pipeline and a secondary charging unit provided inside the gas pipeline; the primary charging unit comprises a primary magnetic core and a primary coil wound around the primary magnetic core; the secondary charging unit comprises a secondary magnetic core and a secondary coil wound around the secondary magnetic core; the primary magnetic core and the secondary magnetic core form a closed magnetic line of force; the primary coil is connected to a power supply, and the secondary coil is connected to a battery of the robot. The charging system has a simple structure, low costs, ease of use, strong anti-interference capability, and high charging efficiency, solves the problem of a need for pipe wall shielding during the charging of a cable-free self-powered inspection robot, and improves the long-distance internal pipeline inspection capacity of the cable-free self-powered inspection robot. The charging method has is easy to implement, convenient to control, safe, reliable, and high in charging efficiency.
