Abstract: Disclosed in the present invention is a multi-operator direct payment system of a public operating service platform for electric vehicles, which belongs to the technical field of electric vehicle operation. The multi-operator direct payment refers to a payment method for the operators where the platform is hosted for the multiple operators. The multi-operator direct payment allows the payment to be directly paid to the actual charging account of the operators through dynamically-targeted payment techniques, without the need for secondary clearing and settlement, which also improves the timeliness of fund arrival, further achieves and promotes the interconnection among the multiple operators. In the traditional operating mode, the money firstly arrives at the platform and is then transferred to the operators, causing the problems of slow fund arrival, extra fees for transfer, and being not subject to the operators' control.
