1. A charging management method for electric vehicle charging stations for use in a charging field with a plurality of electric vehicle charging stations, in which the respective electric vehicle charging station is connected to a server via a network, comprising:
instructing a first charging station to perform a first charging operation for a first electric vehicle via a network by the server, wherein the server sets a first target power parameter value corresponding to the first charging operation, and the power output from the first charging station to the first electric vehicle in the first charging operation will not exceed the first target power parameter value;
monitoring a first power output value actually output from the first charging station to the first electric vehicle during the first charging operation by the server; and
determining whether to adjust the first target power parameter value of the first charging operation according to the first power output value and the first target power parameter value,
wherein the method further comprises:
determining whether the first power output value is lower than the first target power parameter value for a predetermined time;
reducing the first target power parameter value to a second target power parameter value when the first power output value is lower than the first target power parameter value for the predetermined time;
instructing a second charging station among the electric vehicle charging stations to perform a second charging operation for a second electric vehicle via the network by the server, wherein the server sets a third target power parameter value corresponding to the second charging operation, and the power output from the second charging station to the second electric vehicle in the second charging operation is not greater than the third target power parameter value; and
increasing the third target power parameter value corresponding to the second charging operation according to a difference between the first target power parameter value and the second target power parameter value.
