based on the application of the current electric bicycle charging pile, when an electric bicycle is connected with a charging interface of the electric bicycle charging pile for charging, the current of the charging port of the charging pile is detected, the current of the charging port is the current input into the electric bicycle by the electric bicycle through the charging port, under the general condition, the current relates to the storage battery power of the electric bicycle, and the current output by the charging port is the current adaptive to the storage battery power of the electric bicycle. Therefore, based on the charging operation that the current electric bicycle is connected with the electric bicycle charging pile, the charging port current connected with the electric bicycle is detected, and the charging condition of the current electric bicycle is determined according to the charging port current. In general, a storage battery of an electric bicycle may cause a change in a current at a charging port according to a charging condition, and therefore, the charging condition of the electric bicycle is determined by detecting the current at the charging port of the charging pile, in this embodiment, a threshold of the current at the charging port is defined to determine the charging condition of the electric bicycle, the defined threshold of the charging port for determining the charging condition of the electric bicycle is defined as a first preset current, in practical applications, the definition of the first preset current is related to the power of the current electric bicycle storage battery, that is, a corresponding first preset current may be calculated according to the power of the electric bicycle storage battery, and is defined as 0.9A based on the first preset current defined in the method of the present invention. Therefore, according to the limited first preset current, the detected charging port current is compared with the first preset current, and the charging condition of the electric bicycle is confirmed according to the comparison result.

In addition, considering the influence of the charging environment on the current at the charging port when the charging pile is connected with the current, when the charging capacity of the storage battery of the electric bicycle is judged by using a first preset current which is defined in advance, namely when the charging port current is confirmed to be smaller than the first preset current, the sudden change condition of the charging port current is also required to be detected so as to improve the judgment accuracy of the electric quantity of the storage battery of the electric bicycle, therefore, if the charging port current is smaller than or equal to the first preset current, the step of confirming that the electric bicycle connected with the charging port is full in electric quantity comprises the following steps:
continuously detecting the charging port current, and counting the duration of the downward sudden change of the charging port current when the downward sudden change of the charging port current is confirmed;
and if the duration is equal to the preset mutation time, confirming that the electric bicycle is suddenly charged by floating charge and is fully charged.

And step S30, disconnecting the electricity consumption of the charging port and outputting the charging information of the electric bicycle.
When the charging port current is detected, the charging information of the electric bicycle is output, wherein the charging information comprises but is not limited to start charging time, end charging time, charging time length, charging amount, charging port information and other relevant data information for realizing charging operation based on the electric bicycle, so that the charging condition of the electric bicycle can be known in detail based on a server or a user.
In this embodiment, the current threshold value through the accurate definition mouth that charges is used for controlling the down time of electric bicycle in charging process, has improved the corresponding control accuracy when electric bicycle appears the current variation when charging, through reducing the equipment hidden danger problem that the inaccurate machine halt that causes of electric bicycle charges, has realized improving the security that electric bicycle fills electric pile and user experience's beneficial effect.

step S40, if the charging port current is smaller than the first preset current, comparing the charging port current with a second preset current, wherein the second preset current is smaller than the first preset current;
and S50, if the charging port current is less than or equal to the second preset current and lasts for a preset duration, determining that the electric bicycle is full of no-load sudden change.

In addition, regarding the accuracy of the determination of the charging of the electric bicycle storage battery, when the charging port current is detected to be less than or equal to a second preset current, the duration time of the state that the charging port current is less than or equal to the second preset current can be counted, wherein the duration time is an upper limit duration time threshold of the charging port current which is limited to be full in a sudden idle load change mode, that is, when the charging port current is determined to be less than or equal to the second preset current and continues for the preset duration time, the sudden idle load change of the electric bicycle is determined to be full. Further, in order to eliminate the influence of the environment on the charging pile, that is, the further judgment of the accurate charging state of the electric bicycle, the step of determining that the electric bicycle is full of no-load sudden changes based on the current change of the charging port within a first preset time range, that is, if the current of the charging port is less than or equal to the second preset current and lasts for a preset duration, may further include:
