Description

Technical Field

[0001] The present disclosure belongs to the technical field of new energy vehicles, and particularly relates to a method, system, device and medium for preventing a storage battery of a new energy vehicle from discharging. Background Art

[0002] As the core of a new energy vehicle, each controller requires stable power supply to ensure its operation. When the vehicle DC-DC converter DCDC is not enabled, the storage battery serves as the main power source.

[0003] Therefore, it is necessary to ensure the normal operation of the storage battery and prevent it from discharging, which is also the main problem encountered by the current storage battery.

[0004] Currently, the main means to deal with the discharge of the storage battery is to wake up automatically at regular intervals or remotely after the vehicle goes to sleep, detect the voltage, and charge the battery when the battery voltage is lower than a certain value, that is, when it is discharged. The single scenario of this solution cannot cope with other risks such as the discharge of the storage battery when the vehicle is not asleep.

[0005] Therefore, it is necessary to provide a new method, system, device and medium for preventing a storage battery of a new energy vehicle from discharging to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present disclosure is to provide a method, system, device and medium for preventing a storage battery of a new energy vehicle from discharging in order to solve the above problems.

[0007] The present disclosure achieves the above purpose through the following technical solutions:

[0008] A method for preventing a storage battery of a new energy vehicle from discharging includes the following steps:

[0009] Obtain the enabling state of the DCDC of the vehicle, and judge whether the DCDC stops enabling abnormally or normally;

[0010] When the DCDC stops enabling abnormally, the vehicle controller judges and controls the power-off of the vehicle's high voltage according to the obtained vehicle speed and battery voltage;

[0011] When the DCDC stops enabling normally, the body controller requests the vehicle's high voltage to be powered on to charge the battery when the battery is discharged according to the obtained sleep status of the vehicle controller and the battery voltage.

[0012] As a further optimized solution of the present disclosure, the vehicle controller monitors the enabling state of the DCDC, the DCDC fault state, the battery voltage and the vehicle speed in real time; the body controller monitors the enabling state of the DCDC, the DCDC fault state, the battery voltage, and whether the body controller can receive messages in real time.

[0013] As a further optimization solution of the present disclosure, when the DCDC abnormal stop enable is triggered, the vehicle controller determines and controls the vehicle high-voltage power-off according to the acquired vehicle speed and battery voltage, including:

[0014] When the vehicle controller monitors that the DCDC is normally enabled, or the DCDC stop enable is triggered and the DCDC does not malfunction, no action is taken; when the vehicle controller monitors that the DCDC stop enable is triggered and the DCDC malfunctions, the vehicle controller starts to record the number of cycles of the DCDC sending fault messages:

[0015] When the fault messages sent by the DCDC stop within the preset number of cycles n1, no action is taken;

[0016] When the fault messages sent by the DCDC are still received after exceeding the preset number of cycles n1, the vehicle controller starts to judge the battery voltage and vehicle speed: when the battery voltage is greater than the preset voltage V1, no action is taken; when the battery voltage is less than the preset voltage V1 and greater than the preset voltage V2, the instrument is used to prompt that the battery voltage is low; when the battery voltage is less than the preset voltage V2, the instrument is used to prompt that the battery voltage is too low and please pull over as soon as possible. At the same time, the vehicle controller restricts the motor output power to gradually decrease and controls the vehicle high-voltage power-off when the vehicle speed is less than the preset vehicle speed v.

[0017] As a further optimization solution of the present disclosure, when the DCDC normal stop enable is triggered, the body controller requests the vehicle high-voltage power-on to charge the battery when the battery is discharged according to the acquired vehicle controller sleep status and battery voltage, including:

[0018] When the body controller monitors that the DCDC is normally enabled, or the DCDC stop enable is triggered and the DCDC malfunctions, no action is taken;

[0019] When the body controller monitors that the DCDC stop enable is triggered and the DCDC does not malfunction, the body controller starts to judge the battery voltage and whether it can receive messages:

[0020] When the battery voltage is greater than the preset voltage V3 and messages can be received, no action is taken;

[0021] When the battery voltage is greater than the preset voltage V3 and messages cannot be received, the body controller starts to record the number of cycles of not being able to receive messages: if the number of cycles is less than the preset number of cycles n2, no action is taken; if the number of cycles is greater than the preset number of cycles n2, the body controller enters the sleep state;

[0022] When the battery voltage is less than the preset voltage V3, the body controller wakes up the vehicle controller. After the vehicle controller is woken up, it controls the DCDC to be enabled to charge the battery for a preset duration, and then the vehicle controller controls the vehicle high-voltage power-off and the DCDC stop enable.

[0023] A system for preventing the battery of a new energy vehicle from discharging, comprising:

[0024] A judgment module, configured to obtain the enabling state of the vehicle's DCDC, and judge whether the DCDC is abnormally stopped enabling or normally stopped enabling;

[0032] As a further optimization solution of the present disclosure, when the normal stop processing module obtains the DCDC normal stop enable, the body control module requests the vehicle high-voltage power-on according to the obtained sleep status of the vehicle controller and the battery voltage to charge the battery when the battery is discharged, including:

[0037] When the battery voltage is less than the preset voltage V3, the body control module wakes up the vehicle control module. After the vehicle control module is woken up, it controls the DCDC to be enabled to charge the battery for a preset duration, and then the vehicle control module controls the vehicle high-voltage power-off and the DCDC stop enable.

[0048] The following further describes the present application in conjunction with the accompanying drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and cannot be understood as a limitation on the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0049] As Figure 1 shown, a method for preventing the battery of a new energy vehicle from discharging includes the following steps:

[0050] Obtain the enable state of the DCDC of the vehicle, and determine whether the DCDC is abnormally stopped enabling or normally stopped enabling;

[0051] When the DCDC is abnormally stopped enabling, the vehicle controller judges and controls the vehicle high-voltage power-off according to the obtained vehicle speed and battery voltage;

[0052] When the DCDC is normally stopped enabling, the body controller requests the vehicle high-voltage power-on to charge the battery when the battery is discharged according to the obtained sleep status of the vehicle controller and the battery voltage.

[0053] The vehicle controller monitors the DCDC enable state, DCDC fault state, battery voltage, and vehicle speed in real time, and the body controller monitors the DCDC enable state, DCDC fault state, battery voltage, and whether the body controller can receive the messages sent by other controllers in real time.

[0054] As Figure 2 shown, when the DCDC is abnormally stopped enabling, the vehicle controller judges and controls the vehicle high-voltage power-off according to the obtained vehicle speed and battery voltage, including:

[0055] When the vehicle controller monitors that the DCDC is normally enabled, or the DCDC is stopped enabling and the DCDC does not fail, no processing is performed; when the vehicle controller monitors that the DCDC is stopped enabling and the DCDC fails, start recording the number of cycles of the DCDC sending fault messages:

[0056] When the fault messages sent by the DCDC stop within the cycle number n1 (e.g., 100), no processing is performed.

[0057] When the fault messages sent by the DCDC can still be received after exceeding the cycle number n1, start to judge the battery voltage and vehicle speed: when the voltage is greater than V1 (e.g., 12.5V), no processing is performed; when the voltage is less than V1 and greater than V2 (e.g., 11V), prompt the driver "Low battery voltage" through the instrument; when the voltage is less than V2, prompt the driver "The battery voltage is too low, please pull over as soon as possible" through the instrument, and at the same time, the vehicle controller restricts the motor output power to gradually decrease and controls the vehicle high-voltage power-off after the vehicle speed is less than v (e.g., 3km / h).

[0058] When the DCDC normally stops enabling, the body controller requests the vehicle high-voltage power-on to charge the battery according to the obtained vehicle controller sleep status and battery voltage, including:

[0059] When the body controller monitors that the DCDC is normally enabled, or the DCDC stops enabling and the DCDC fails, no processing is performed; when the body controller monitors that the DCDC stops enabling and the DCDC does not fail, start to judge the battery voltage and whether the messages sent by other controllers can be received:

[0060] ① When the voltage is greater than V3 (e.g., 12.5V) and the messages sent by other controllers can be received, no processing is performed;

[0061] ② When the voltage is greater than V3 and the messages sent by other controllers cannot be received, start to record the cycle number when the messages sent by other controllers cannot be received. If the cycle number is less than n2 (e.g., 100), no processing is performed. If the cycle number is greater than n2, the body controller enters the sleep state;

[0062] ③ When the voltage is less than V3, the body controller wakes up the vehicle controller. After the vehicle controller is woken up, it controls the DCDC to enable to charge the battery for a certain period of time (e.g., one hour), and then the vehicle controller controls the vehicle high-voltage power-off and the DCDC stops enabling.

[0063] As Figure 3 shown, the embodiment of the present disclosure provides a new energy vehicle anti-battery power shortage system, including:
