The embodiment of the invention relates to the field of rail transit, and discloses a traction system and method of a rail transit vehicle, electronic equipment and a storage medium, the traction system comprises a traction inverter, a traction motor, a storage battery power supply circuit, an auxiliary converter and a control unit; when the rail transit vehicle is in a storage battery traction mode, a control unit controls a storage battery power supply branch to obtain electricity from a storage battery, and an auxiliary converter boosts obtained direct current and then provides the direct current to a traction inverter for conversion to obtain three-phase alternating current for driving a traction motor to rotate; and when the rail transit vehicle is in the external power supply traction mode, the traction inverter is controlled to obtain electricity from the external network alternating current power supply, and the obtained electric energy is converted into three-phase alternating current to drive the traction motor to rotate. According to the scheme, the traction power comprising the storage battery traction mode and the external power supply traction mode is provided for multiple scenes, so that the vehicle can flexibly switch the traction modes according to actual scene requirements.
