Abstract: A motor control circuit includes a first switch module, a three-phase inverter, and a control module, where a power supply module, the first switch module, the three-phase inverter, and a three-phase alternating current motor form a current loop, the three-phase alternating current motor inputs or outputs a current by using a wire N extending from a connection point of three phase coils, and the control module controls the three-phase inverter, so that the motor control circuit receives a voltage of the power supply module and outputs a direct current. A wire N extends from the three-phase alternating current motor, and further forms different charging loops with the three-phase inverter, the three-phase alternating current motor, and the power battery.

Abstract: The present disclosure discloses a system and a method for developing a third-party application. The system includes: a vehicle-mounted device and a developer platform communicating with each other. The vehicle-mounted device generates a corresponding API according to a protocol analysis mode of a vehicle signal and API specifications, adds the API to a software development kit SDK, and sends the API to the developer platform. The developer platform publishes the SDK so that a developer can develop a third-party application according to the API in the SDK.
