[0025] In the related art, in order to prevent the battery from discharging, common methods include: using an active anti-discharge intelligent control circuit, making the controller enter a low-power mode to reduce the dark current consumption, disconnecting the battery connection, and starting the engine regularly, etc. However, these methods all reduce the power consumption of the vehicle through corresponding strategies or directly start the vehicle engine to charge the battery, and cannot supplement energy to the battery in the vehicle from the outside.

As Figure 1 shown, the battery anti-discharge system includes a charging system, the charging system includes a power generation device, and the power generation device is provided on the vehicle body of the target vehicle;
[0028] Among them, the power generation device is connected to the first charging device of the battery in the target vehicle.
[0029] When the target vehicle meets the lighting conditions, the charging system is configured to respond to the current state of the target vehicle being in the off state and the current voltage of the battery being less than the first preset threshold, and charge the battery through the power generation device.
[0030] Exemplarily, the power generation device can be a solar photovoltaic panel. Among them, the solar photovoltaic panel can be a rigid photovoltaic panel, a flexible photovoltaic panel, etc.
[0031] In a possible implementation manner, a power generation device such as a solar photovoltaic panel is attached to the body surface of the target vehicle.
[0032] In a possible implementation manner, the power generation system may include a control circuit, which is used to control the connection and disconnection of the power generation device and the first charging device of the storage battery in the target vehicle, and when the connection state of the power generation device and the first charging device of the storage battery in the target vehicle is controlled through the control circuit, the storage battery is charged through the power generation device. Exemplarily, the input end of the control circuit may be connected to the power generation device, and the first output end of the control circuit may be connected to the first charging device of the storage battery.
[0033] It should be noted that the embodiments of the present application do not specifically limit the control circuit, as long as it can control the connection or disconnection of the power generation device and the first charging device in the storage battery.
[0034] Exemplarily, when the target vehicle detects the light intensity on the body surface through the sensor, it indicates that the target vehicle meets the light conditions. In the embodiments of the present application, the specific magnitude of the light intensity is not limited.
[0035] Exemplarily, the current state of the target vehicle can be obtained by detecting the operating state of the engine and / or the motor. For example, when the engine and / or the motor is in the operating state, it is determined that the target vehicle is in the starting state, and when the engine and / or the motor is in the non-operating state, it is determined that the target vehicle is in the off state.
[0036] Exemplarily, the first preset threshold may be the rated voltage of the storage battery in the target vehicle.
[0037] Exemplarily, the magnitude of the first preset threshold may be 12V, or may be 24V, etc. In the embodiments of the present application, the specific magnitude of the first preset threshold is not limited, and it can be determined specifically according to the actual application requirements.
[0038] In a possible implementation manner, when the target vehicle meets the light conditions, and it is detected that the target vehicle is in the off state, and the current voltage of the storage battery in the target vehicle is less than the first preset threshold, the power generation device in the charging system and the first charging device of the storage battery in the target vehicle are connected to charge the storage battery through the power generation device.
[0039] In the embodiment of the present application, the system for preventing the battery from discharging includes a charging system, which comprises a power generation device. The power generation device is arranged on the body of the target vehicle and is connected to the first charging device of the battery in the target vehicle. When the target vehicle meets the lighting conditions, the charging system is configured to respond that the current state of the target vehicle is the off state and the current voltage of the battery is less than the first preset threshold, and charge the battery through the power generation device. In the embodiment of the present application, by arranging a power generation device on the body of the target vehicle and charging the battery in the target vehicle through the charging system including the power generation device when the target vehicle meets the lighting conditions, energy is supplemented to the battery in the target vehicle from the outside, thereby avoiding the vehicle from being unable to start due to battery discharge.
[0040] Optionally, in the system for preventing the battery from discharging provided by the embodiment of the present application, the power generation device is also connected to the second charging device of the power battery in the target vehicle; the charging system is further configured to respond that the current state of the target vehicle is the off state, the current voltage of the battery is equal to the first preset threshold, and the current power of the power battery is less than the second preset threshold, and charge the power battery through the power generation device; or, respond that the target vehicle is in the start state and the current power of the power battery is less than the second preset threshold, and charge the power battery through the power generation device.
[0041] In a possible implementation manner, the power generation system may include a control circuit, which is configured to control the connection and disconnection of the power generation device and the second charging device of the power battery in the target vehicle, and charge the power battery through the power generation device when the control circuit controls the power generation device and the second charging device of the power battery in the target vehicle to be in the connected state. Exemplarily, the input end of the control circuit may be connected to the power generation device, the first output end of the control circuit is connected to the first charging device of the battery, and the second output end of the control circuit is connected to the second charging device of the power battery.
[0042] It should be noted that the embodiment of the present application does not make specific limitations on the control circuit, as long as it can control the connection or disconnection of the power generation device and the second charging device in the power battery.
[0043] The specific determination method for the target vehicle to be in the start state is similar to the above, and will not be elaborated here.
[0044] Exemplarily, the second preset threshold may be 100%. In the embodiment of the present application, the size of the second preset threshold is not limited, and it can be determined specifically according to actual application requirements.
[0045] It can be understood that when the current power of the power battery is less than the second preset threshold, it indicates that the power of the power battery is not in the full charge state.
[0046] In a possible implementation, when the target vehicle meets the lighting conditions, and it is detected that the target vehicle is in the flameout state, the current voltage of the storage battery in the target vehicle is equal to the first preset threshold, and the current power of the battery in the target vehicle is less than the second preset threshold, the power generation device in the charging system is controlled to be connected to the second charging device of the power battery in the target vehicle, so as to charge the power battery through the power generation device.
[0047] In a possible implementation, when the target vehicle meets the lighting conditions, and it is detected that the target vehicle is in the starting state, and the current power of the battery in the target vehicle is less than the second preset threshold, the power generation device in the charging system is controlled to be connected to the second charging device of the power battery in the target vehicle, so as to charge the power battery through the power generation device.
[0048] It can be understood that in the anti-battery discharge system provided by the embodiments of the present application, when the target vehicle is in the flameout state, when the power generation device charges the storage battery and the power battery, the charging priority of the storage battery is higher than that of the power battery, so as to prevent the target vehicle from failing to start due to the discharge of the storage battery. When the target vehicle is in the starting state, the storage battery can be charged by the engine and / or the motor in the target vehicle. Therefore, in this scenario, the power generation device only charges the power battery in the target vehicle.
[0049] Figure 2 Structural schematic of the anti-battery discharge system provided by the embodiments of the present application Figure 2 As Figure 2 shown, the anti-battery discharge system includes a charging system and a first controller. Among them, the charging system includes a power generation device and a second controller, and the first controller and the second controller are communicatively connected.
[0050] Among them, the second controller is used to respond to the target vehicle meeting the lighting conditions, send a request signal to the first controller, so that the first controller responds to the request signal, obtains the vehicle information of the target vehicle, and sends the vehicle information to the second controller. The vehicle information includes the current state of the target vehicle, the current voltage of the storage battery, and the current power of the power battery in the target vehicle;
[0051] The second controller is also used to respond to the vehicle information, control the power generation device to be connected to the first charging device of the storage battery to charge the storage battery; or control the power generation device to be connected to the second charging device of the power battery to charge the power battery.
[0052] Exemplarily, the second controller may be the vehicle controller of the target vehicle.
[0053] In a possible implementation, when the target vehicle meets the lighting conditions, the second controller sends a request signal to the first controller to instruct the first controller to obtain the vehicle information of the target vehicle, so that when the second controller receives the request signal sent by the second controller, it obtains the vehicle information of the target vehicle, such as the current state of the target vehicle, the current voltage of the battery, and the current power of the power battery in the target vehicle, etc., and sends the corresponding vehicle information to the second controller.
[0054] In some embodiments, after the second controller receives the vehicle information sent by the first controller, when it determines that the current state of the target vehicle is the off state, and the current voltage of the battery is less than the first preset threshold and the current power of the power battery is less than the second preset threshold, it controls the power generation device to be connected to the first charging device of the battery and the second charging device of the power battery respectively to charge the battery, and when the voltage of the battery is equal to the first preset threshold, it charges the power battery.
[0055] In some embodiments, after the second controller receives the vehicle information sent by the first controller, when it determines that the current state of the target vehicle is the off state and the current voltage of the battery is greater than or equal to the first preset threshold, it controls the power generation device to be connected to the second charging device of the power battery to charge the power battery.
[0056] In some embodiments, after the second controller receives the vehicle information sent by the first controller, when it determines that the current state of the target vehicle is the off state, the current voltage of the battery is less than the first preset threshold, and the current power of the power battery is greater than or equal to the second preset threshold, it controls the power generation device to be connected to the first charging device of the battery to charge the battery.
[0057] In some embodiments, after the second controller receives the vehicle information sent by the first controller, when it determines that the current state of the target vehicle is the start state and the current power of the power battery is less than the second preset threshold, it controls the power generation device to be connected to the second charging device of the power battery to charge the power battery.
[0058] The anti-battery-discharge system provided by the embodiments of the present application, on the one hand, realizes energy replenishment of the battery in the target vehicle from the outside, thereby avoiding the vehicle being unable to start due to battery discharge. At the same time, it can also realize charging of the power system in the target vehicle, such as the power battery; on the other hand, when charging the battery through the power generation device in the charging system until the voltage of the battery is equal to the first preset threshold, the connection between the power generation device and the first charging device of the battery is automatically disconnected to prevent overcharging of the battery.
[0059] Optionally, in the system for preventing battery power shortage provided by the embodiments of the present application, the second controller in the charging system is further configured to control the power generation device to disconnect from the first charging device and / or control the power generation device to disconnect from the second charging device when at least one of the following conditions is met: the voltage of the battery is greater than or equal to a first preset threshold, the power of the power battery is greater than or equal to a second preset threshold, and the target vehicle does not meet the lighting condition.
[0060] In some embodiments, when the target vehicle does not meet the lighting condition, the power generation device is controlled to disconnect from the first charging device of the battery, and the power generation device is controlled to disconnect from the second charging device of the power battery.
[0061] In some embodiments, when the target vehicle meets the lighting condition and the voltage of the battery is greater than or equal to the first preset threshold, the power generation device is controlled to disconnect from the first charging device of the battery.
[0062] In some embodiments, when the target vehicle meets the lighting condition and the power of the power battery is greater than or equal to the second preset threshold, the power generation device is controlled to disconnect from the second charging device of the power battery.
[0063] In some embodiments, when the target vehicle meets the lighting condition, the voltage of the battery is greater than or equal to the first preset threshold, and the power of the power battery is greater than or equal to the second preset threshold, the power generation device is controlled to disconnect from the first charging device of the battery, and the power generation device is controlled to disconnect from the second charging device of the power battery.
[0064] In the embodiments of the present application, when the voltage of the battery is greater than or equal to the first preset threshold, the power generation device is controlled to disconnect from the first charging device of the battery to prevent overcharging of the battery; when the power of the power battery is greater than or equal to the second preset threshold, the power generation device is controlled to disconnect from the second charging device of the power battery to prevent overcharging of the power battery.
[0065] Optionally, in the system for preventing battery power shortage provided by the embodiments of the present application, the second controller in the charging system is further configured to send a request signal to the first controller after a preset duration starting from the first timestamp when the power generation device is controlled to disconnect from the first charging device or the second timestamp when the power generation device is controlled to disconnect from the second charging device; wherein, within the preset duration, the target vehicle meets the lighting condition.
[0066] Exemplarily, the preset duration can be 4 hours. In the embodiments of the present application, the specific size of the preset duration is not limited and can be determined according to actual application requirements.
[0067] It can be understood that in the battery power loss prevention system provided by the embodiments of the present application, when the target vehicle meets the lighting conditions, after the charging system completes a primary charge of the battery and / or the power battery, at every preset time interval, the charging system will be automatically started to send a request signal to the second controller to start the second charge of the battery and / or the power battery, and so on for cyclic charging of the battery and / or the power battery.
[0068] It should be noted that in any of the above cyclic processes, if there is a situation where the target vehicle does not meet the lighting conditions, the cycle is interrupted, and when the target vehicle meets the lighting conditions again, the charging system is automatically started to send a request signal to the second controller and start the above cyclic process.
[0069] Next, taking the battery power loss prevention system described in the above embodiments as the execution subject, the battery power loss prevention method provided by the embodiments of the present application will be described in detail in combination with specific embodiments.

When the voltage of the battery is equal to the first preset threshold, the second controller controls the disconnection of the power generation device in the charging system from the first charging device of the battery, and continues to charge the power battery through the power generation device until the power of the power battery is equal to the second preset threshold, and the second controller controls the disconnection of the power generation device in the charging system from the second charging device of the power battery.
