Provided is an energy-storage type trolley car energy saving control method. An air conditioning system is interlocked with a PIS and a door control system through a whole vehicle controller, vehiclearriving station and loading situations control the operation of the air conditioning system in real time; vehicle current GPS data, load sensor and the vehicle surplus electric quantity situation areuploaded to a server, according to the above data, the server combines the remaining distance distant from the next station, the remaining time arriving the next station and front road situation information to calculate optimum traction, optimum cruising speed and the optimum braking position point and transmits the optimum traction, the optimum cruising speed and the optimum braking position point to the whole vehicle controller, the whole vehicle controller carries out driving according to a big data calculation result, so that the energy utilization rate reaches a maximum value. The energy-storage type trolley car energy saving control method has the advantages that the whole vehicle controller combines big data, a global positioning system and an artificial intelligence algorithm to achieve the energy saving operation of the whole vehicle under the situation of not increasing any equipment, the energy is used to needed places, and the energy utilization rate is greatly improved.
