值得说明的是，本发明不限定是先充电后缴费，还是先缴费后开始充电，若是前者，则计费服务器在预计算得到费用信息后，向用户发送缴费请求消息，在确认用户缴费成功后，再开始对电动汽车充电，在此种情况下，若充电过程中发生中断，例如用户提前断开充电连接离开，则计费服务器还需将余额返还到用户账户；若是后者，则计费服务器可以在充电完成后，计算电动汽车本次充电实际花费的费用，并向用户发送缴费请求消息，请求用户缴费。It should be noted that the present invention is not limited to charging after charging first, or charging after starting payment. If the former, the charging server sends a payment request message to the user after pre-calculating the fee information, after confirming that the user pays successfully. Then, the electric vehicle is charged again. In this case, if the charging process is interrupted, for example, if the user disconnects the charging connection in advance, the charging server needs to return the balance to the user account; if the latter, the billing is performed. After the charging is completed, the server can calculate the actual cost of the electric vehicle for the current charging, and send a payment request message to the user to request the user to pay the fee.
