The power source of new energy vehicles is the battery, and the number of times the battery can be charged directly affects how long the vehicle can run. In order to protect the battery of the new energy vehicle and avoid excessive charging affecting the service life of the battery, the vehicle equipped with the vehicle networking function needs to set the charging time of the vehicle battery.

[0003] The current commonly used charging method has a small deviation in the recording time of the clock crystal oscillator of the vehicle networking assembly part in the actual operation process.

[0047] Embodiment 1

[0048] Reference Figure 1 For an embodiment of the present application, an electronic timing processing method for new energy vehicle reservation charging is provided, comprising:

[0049] S1: The mobile phone APP sets and sends a reservation charging instruction.

[0050] Further, the mobile phone APP sends the reservation charging instruction to the T-BOX, and the T-BOX sends the reservation charging instruction to the Internet of Vehicles, and the network chip of the Internet of Vehicles host receives it and transmits it to the MCU.

[0051] It should be noted that the reservation information should include the reservation time, the charging time and the charging state selection.

[0052] S2: Receive GPS time, and update the GPS time in real time after the reservation charging instruction is issued.

[0053] Further, the real-time updating of the standby GPS time includes that when the T-BOX in the Internet of Vehicles is normally running, the GPS time is received in real time, and when the vehicle receives a preset instruction, the MCU suspends the updating of the current GPS time instruction received by the T-BOX, stops the action of comparing the GPS time, and refers to the RTC current time to trigger the event.

[0054] It should be noted that when the preset instruction is received, the action of comparing the GPS time is stopped, and the RTC current time is directly referred to for timing. After the preset event is triggered, the current time of the Internet of Vehicles is updated by comparing the GPS. After the GPS time is closed, the occurrence of the second skipping phenomenon can be effectively avoided.

[0055] S3: Calculate the difference between the predetermined time and the current time, set the difference as the RTC timer time, and determine whether to wake up the vehicle to charge.

[0056] Further, the MCU subtracts the current time of the RTC from the APP instruction time to obtain a time difference,

[0057] If the time difference < 0, it is considered as an overtime reservation, and the user needs to reselect the reservation time. The overtime instruction is sent from the vehicle network to the mobile phone APP, showing that the reservation is overtime, and reminding the user to re-reserve;

[0058] If the time difference ≥ 0, the time difference is set as the RTC timer time, and the reservation success instruction is sent from the vehicle network to the mobile phone APP, showing that the reservation is successful.

[0059] It should be noted that determining whether to wake up the vehicle to charge includes,

[0060] If the RTC timer time is not zero, re-determine until the RTC timer time is zero;

[0061] If the RTC timer time is zero, prepare to wake up the vehicle to charge, and restore the MCU to receive the time instruction of the T-BOX, accept the real-time update of the GPS time, restore the RTC time update logic, and convey the charging instruction to the CAN bus supervision system.

[0062] S4: Convey the charging instruction through the CAN bus supervision system.

[0063] Further, conveying the charging instruction through the CAN bus supervision system includes, when the CAN bus receives the wake-up vehicle to charge operation instruction,

[0064] If the customer sets the charging time, the CAN bus supervision system sends three frames of instructions to the charging pile, including the data frame of the frame start charging instruction, the frame interval, and the data frame of the charging end failure;

[0065] If the customer does not set the charging time, the CAN bus supervision system sends two frames of instructions to the charging pile, including the data frame of the start charging instruction, the frame interval, and the data frame of the full power feedback.

[0066] It should be noted that the CAN bus supervision system also includes,

[0067] If the customer sets the charging time, and the time ends with the battery power < 80%, the CAN bus supervision system sends three frames of instructions to the charging pile, including the remote control frame of the charging state, the frame interval, and the remote control frame of the charging request, and the instruction is transmitted to the mobile phone APP by the vehicle network. The customer judges whether to continue charging according to the information;

[0068] If the customer sets the charging time, and the battery power ≥ 80% before the end of the charging time, the CAN bus supervision system sends three frames of instructions to the charging pile, including the remote control frame of the charging state, the frame interval and the remote control frame of the full power prediction, and the time ends cannot be fully charged, the instructions are transmitted to the mobile phone APP by the Internet of Vehicles, and the customer judges whether to extend the charging time according to the information;

[0069] If the customer does not set the charging time or the customer sets the charging time before the battery is fully charged, the CAN bus supervision system sends three frames of instructions to the charging pile, including the remote control frame of the vehicle full power, the frame interval and the data frame of stopping charging, and the instructions are transmitted to the mobile phone APP by the Internet of Vehicles, and the user is informed that the battery is fully charged.

[0070] It should be noted that the battery power is fed back at the threshold point of 80, because some charging piles are fast charging, the charging speed of fast charging is fast, but the current is larger, and it is direct current, the power is generally between 30KW-100KW, and 20% is reserved for charging piles of various powers, which can prevent the battery from short circuiting and causing danger; Secondly, it can reduce the battery cycle. The battery of a new energy vehicle is generally used in terms of cycle number. If the battery is fully charged and continues to be charged, it will cause the cycle number of the vehicle battery to increase, and the performance of the battery will gradually decrease over a long period of time, and the service life will also be greatly reduced. Therefore, the power is fed back to the user at 80, and whether it is full is judged according to the user's demand.

[0071] Embodiment 2

[0072] Reference Figure 2 For an embodiment of the present application, an electronic timing processing method for new energy vehicle reservation charging is provided. In order to verify the beneficial effects of the present application, economic benefit calculation and simulation experiment are used for scientific demonstration.

[0073] As shown in the table, a field experiment of the present application is carried out, and new energy vehicles BYD Han are selected for the experiment, and a total of 2 vehicles are used to complete 30 charging experiments for each vehicle according to the traditional technical scheme and the technical scheme of the present application.

[0074] Number of seconds jumps Number of charging judgment errors Full charge voltage ratio before and after experiment Our invention 0 0 100.003％ Conventional technical solution 2 1 100.01％

[0075] According to the data comparison table, it can be seen that the present application does not occur in 30 charging experiments. Without the present application, the time is not judged according to the GPS time, and there is no possibility of skipping seconds. The number of charging judgment errors is also 0, because the RTC time judgment logic is only yes or no, the judgment logic is simple, and it is not easy to make mistakes. Because the CAN bus is used for supervision and feedback, the service life is reduced due to excessive or fast charging.

[0076] From Figure 2As can be seen from the comparison of the voltage change of 30 times of charging, the voltage of the application is almost unchanged, and the voltage of the full battery of the traditional technical solution changes greatly, and the full battery voltage can show the service life of a battery, and since the application can feedback the charging state, the damage of charging to the battery can be reduced.
