CHARGING MODULE AND CHARGING DEVICE

Embodiments of this application disclose a charging module (400) and a charging device, and relate to the field of power electronics technologies, to resolve a problem of how to implement a charging module with a simple structure, low costs, and high reliability. The charging module includes a controller (410), a resistor (R), an AC-DC power conversion circuit (420), and two switches (K1, K2). Three input ends of the AC-DC power conversion circuit (420) are respectively configured to connect to three phase output ends of an alternating current power supply (200) in a one-to-one correspondence manner, the three input ends of the AC-DC power conversion circuit (420) are further separately configured to connect to a ground end via capacitors (C1-C3), the two switches (K1, K2) are respectively disposed between two input ends of the AC-DC power conversion circuit (420) and two corresponding phase output ends of the alternating current power supply (200), and the resistor (R) is connected in parallel to a first switch (K1) in the two switches. The controller is configured to: when an absolute value of a voltage difference between two ends of the resistor is less than or equal to a first voltage threshold, control the first switch to be turned on.
