The invention discloses a flexible charging method for a tramcar, and relates to the technical field of charging of the tramcar. According to the flexible charging method for the tramcar, a photo-thermal power station, a tramcar platform, a box-type substation, a vehicle-mounted super capacitor, a vehicle-mounted lithium titanate battery and a ground energy storage system are included, and the box-type substation comprises an EMS energy management system, a BMS battery management system, a direct-current switch cabinet, a transformer, a rectifier and a feeder isolation cabinet. The EMS energy management system can adjust the charging power according to the tramcars with different car conditions, the service life of the vehicle-mounted super capacitor and the vehicle-mounted lithium titanate battery is prolonged, the vehicle-mounted super capacitor ensures that the vehicle is fully charged within 30 seconds after entering the station, the dynamic balance of vehicle energy consumption and supply is realized, the whole-course uninterrupted operation of the vehicle is ensured, and the service life of the vehicle-mounted super capacitor and the vehicle-mounted lithium titanate battery is prolonged. The vehicle-mounted lithium titanate battery can compensate power supply for the vehicle in an emergency state, and the method is suitable for a modern tramcar project with sufficient illumination, super capacitor and lithium titanate battery power supply and multiple new energy input.
