Drawings

Fig. 1 is a flowchart of a method for implementing a remote charging reservation according to the present invention.

Detailed Description

The embodiment is described with reference to fig. 1, and a method for implementing remote reservation charging can implement the following functions: adding a new reservation charge, canceling the reservation charge, starting the reservation charge and detecting the charge state;

newly-increased reservation charging: the TSP service platform issues an instruction to enable the T-BOX to be in a waiting state, the T-BOX returns a response result, and the TSP service platform updates the charging record of the database according to the response of the T-BOX; description of the reserved charge value: subscription 0 failure subscription 1 subscription was successful.

Canceling the reserved charging: the TSP service platform issues an instruction, the T-BOX returns a response result, and the platform updates the charging record of the database according to the response of the T-BOX; description of the reserved charge value: and 2, canceling the reservation.

Starting the reserved charging: and (5) inquiring a timed task polling database by 20S, judging whether the charging starting time is reached, if so, issuing an instruction to the T-BOX to enable the T-BOX to be in an active state, returning a response result to the BOX, and updating the charging record state by the TSP service platform according to the response of the T-BOX.

And (3) detecting the charging state: TSP service platform 10S periodically queries T-BOX report value (value in 530), and updates database value

Updating the state of the mobile phone APP: and the APP terminal polls and updates the display.

In this embodiment, the TSP service platform issues a charging instruction to the T-BOX; the T-BOX acquires a vehicle state feedback value after issuing the command to the vehicle; the platform judges a synchronous database value according to the vehicle feedback value, when the response is 0x00 or 0x08, the platform updates the database value (TBOX should not be 0 during reserved charging) according to the T-BOX report value (530 value), and the APP calls an interface to display the charging state in the APP.

Reporting the answer value	Means of
		0x00	Control success
0x01	Incorrect power mode, control failure
		0x02	When BCM random number is acquired, control is failed
0x03	BCM authentication failure, control failure
		0x04	Post-control result feedback failure
0x05	The door is not closed and the control fails
		0x06	Please wait for 15s in arming mode, control fails
0x07	Charging gun not connected, charging failure
		0x08	Is being charged
0x09	Charging is completed
		0x0a	Charging failure
0x0b	Unbound vehicle, control failure
		0x0c	Non-support of charging in ON state
0x0d	Too low power, control failure

The specific flow of the embodiment is as follows:

step one, charging is reserved by a mobile phone APP, the reserved time is limited within 24h, and a TSP service platform judges whether a charging gun is connected or not; vehicle state of charge signal VCU _ SlowChargeGunStatus, if yes, APP plays the frame suggestion: your good! If the vehicle is charging, if the reservation charging needs to be added, the system automatically cuts off the current charging, and whether the operation is executed or not is judged, and the step two is executed; if not, the APP bullet frame prompts that the user has successfully reserved, the vehicle is charged in X months X days X minutes X seconds in X years, and the charging gun is required to be normally connected with the vehicle; executing the step two;

step two, setting a reserved time t, judging whether the t is behind the current time, and if not, resetting; if yes, the TSP service platform sends a charging reservation mark to the T-BOX;

step three, after the T-BOX is awakened, sending a charging reservation request to the VCU, wherein the charging reservation is waiting for a command signal T-BOX _ ScheduleTargetSOCSign which is waiting for waiting, and the T-BOX is responsible for awakening the whole vehicle network;

the VCU feeds back the reserved charging state to the T-BOX, the APP is delivered through the platform that the reserved charging is successful, and the VCU executes a reserved charging waiting signal VCU _ ScheduleTargetSOCSign which is 0X 1: waiting;

step four, the VCU judges whether the charging is in progress, if so, the whole vehicle network returns to the dormant state after the conditions are met, the TSP service platform makes an appointment to start charging countdown, and the step five is executed; if not, the VCU interrupts the current charging and continues to judge;

step five, the TSP service platform judges whether the appointment time is reached, if yes, the TSP service platform sends a charging permission instruction to the T-BOX, the T-BOX sends the charging permission instruction to the VCU, and a charging start execution signal T-BOX _ ScheduleTrgetSOCign is Active;

feeding back the execution state to the T-BOX by the VCU, feeding back the charging state to the T-BOX by a reserved charging feedback result signal VCU _ ScheduledFeedbackStatus, and executing a sixth step;

step six, the VCU judges whether the charging condition is met, if so, the VCU controls to start normal charging, and the BMS feeds back the charging state: vehicle data information such as charging current, charging voltage, charging remaining time, current SOC and the like;

feeding back a charging starting appointment charging feedback result signal VCU _ ScheduledfeedbackStatus state to the T-BOX by the VCU, uploading the T-BOX to the TSP service platform, feeding back the TSP service platform to the mobile phone APP, and executing the step seven; if not, the VCU feeds back the current state to the T-BOX: a reserved charging feedback result signal VCU _ ScheduleFeedbackStatus, T-BOX is fed back to the TSP service platform, the TSP service platform feeds back to the mobile phone APP, and the reserved charging is finished at the same time;

step seven, the VCU judges whether the charging gun is pulled out, if so, the VCU feeds back the current state to the T-BOX: a reserved charging feedback end signal VCU _ ScheduleFeedbackStatus, T-BOX is fed back to the TSP service platform, the TSP service platform feeds back to the mobile phone APP, and the reserved charging is ended at the same time; if not, after the electric quantity is full, the VCU feeds back the state to the T-BOX, the T-BOX feeds back the charging to the TSP service platform, and the TSP service platform feeds back to the mobile phone APP;

and the VCU executes a charging ending command, executes a normal charging finishing strategy and sets the charging ending command T-BOX _ ScheduleTrgetSOCign as Inactive.

In the embodiment, when the T-BOX vehicle is dormant and the reserved charging time is reached, the vehicle displays normal charging, but when the APP terminal displays charging failure, the following method is adopted to solve the problem:

when the reserved charging starting time is reached, the TSP service platform issues an instruction to the T-BOX, the T-BOX returns a 08(08 is charging), then the platform updates the APP charging state to 3(3 is charging) according to the response of the T-BOX, then the value of 530 is obtained, the value of 530 signal is not reported and updated, so that the previous 530 signal value is obtained, namely 0, the APP shows that the charging fails

Now, the modification: when the acquired value 530 is 0, active state time of reserved charging is detected, if the time is less than 10s from the current time, the current 530 is not the latest report, and the data updating is abandoned.

3. 530, signal reporting: and (4) reporting the charging fault (0X04) at a limited time (100MS once, 10 times of reporting for 1 second in total), and then reporting to 0X 00.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
