step six, the charging pile subtracts the residual electric quantity of the battery according to the electric quantity corresponding to the charging percentage of the battery to calculate the charging electric quantity required by the battery, the calculation formula is as follows,
Qcharging device＝QOrder to－QFirst stage
QFirst stageIs the value of the remaining capacity of the battery, QOrder toThe amount of electricity, Q, corresponding to the percentage of battery chargeCharging deviceThe charging capacity required by the battery;
step seven, the charging pile charges according to the charging power and the charging QCharging deviceCalculating the predicted charging time after charging is completed, sending the predicted charging time to a server side, sending the predicted charging time to the mobile phone client side by the server side, and generating the two-dimensional code for payment by the charging pile and displaying the two-dimensional code on the liquid crystal display screen;
step eight, the user uses the mobile phone client to scan the two-dimensional code and pays the charging cost;
step nine, the charging pile charges the battery, and when the charging electric quantity reaches QCharging deviceAnd the charging pile is disconnected from charging.
5. The method of claim 4, wherein the battery power characteristic data further includes a model number of the electric bicycle, the model number of the electric bicycle is adapted to the corresponding model number of the battery, and in step three, the user can select the corresponding model number of the battery by selecting the model number of the electric bicycle to be charged, so as to perform the charging operation.
6. The method as claimed in claim 5, wherein the mobile phone client has a feedback option, and when the user does not find the corresponding battery type in the lcd of the charging post, the user fills the battery type in the feedback option of the mobile phone client and sends the battery type to the server.
7. The method as claimed in claim 5, wherein when the percentage of the battery charge is selected by a user at the LCD of the charging post, the predicted driving distance of the brand model of the electric bicycle is displayed on the LCD.
8. The method for controlling the amount of charge on a battery of an electric bicycle according to claim 4, wherein the amount of charge on the battery reaches QCharging deviceAnd when the charging pile is used, a completion signal is sent to the server side, and the server side sends the completion signal to the mobile phone client side to remind a user that charging is completed.
