Description

Technical Field

[0001] The present invention relates to the technical field of protection of a battery thermal management module for new energy vehicles, and in particular to a battery thermal management module shield, a control method, and a system. Background Art

[0002] With the rapid development of new energy commercial vehicles, power battery thermal management has become a core issue affecting vehicle range, safety, and lifespan. Traditional protective covers often use fixed vents, making it impossible to dynamically adjust air volume based on the power battery and ambient temperatures. This leads to low energy efficiency in the battery thermal management module, which in turn affects the performance of the power battery thermal management system and, to a certain extent, the vehicle's range. Furthermore, commercial vehicles often face harsh operating conditions such as dust, flying rocks, mud, and high-pressure water jets. Traditional protective covers struggle to balance heat dissipation requirements with dust and water resistance, resulting in poor environmental adaptability.

[0003] CN112638116B provides an automatic heat dissipation system for electrical equipment and electrical equipment using the system, the automatic heat dissipation system for electrical equipment comprising: a venetian blind; a temperature sensor; a water immersion sensor; a controller; and a fan; the venetian blind comprising a control device for controlling the opening or closing of the blades, the control device being connected to the controller; the controller having a first working state in which the blades are kept closed and the fan is controlled to be turned on when the temperature inside the cabinet exceeds a set value but the water immersion sensor detects that the electrical equipment has been exposed to rain, thereby achieving heat dissipation inside the cabinet; the controller also having a second working state in which the blades are controlled to be opened and the fan is controlled to be turned on when the temperature inside the cabinet exceeds a set value and the water immersion sensor detects that the equipment has not been exposed to rain, thereby achieving ventilation and heat dissipation; the controller also having a third working state in which, after the blades are opened, the temperature inside the cabinet is lower than a set value or the water immersion sensor detects that the equipment has been exposed to rain, thereby controlling the blades to be closed, thereby preventing rainwater from entering the equipment and preventing accidents.

[0004] However, the prior art does not provide a control system and method for heat dissipation of the charging device that can meet the requirements of combining various working modes of the battery thermal management module with temperature and waterproofing. Summary of the Invention

[0005] The present invention provides a battery thermal management module shield, control method, and system. While ensuring the waterproof and dustproof requirements of new energy commercial vehicles, the shield improves the working efficiency of the battery thermal management module, reduces the failure rate, and extends the maintenance cycle through the linkage control of multiple parameters such as the battery thermal management module operating mode, ambient temperature, and waterproofness. This effectively alleviates the problems of low energy efficiency and poor environmental adaptability of existing technologies.

[0006] The present invention provides the following solutions

[0007] A battery thermal management module shield control method includes the following steps:

[0008] S1. Determine whether the battery thermal management module is in working state;

[0009] S2. If yes, determine the operating mode of the battery thermal management module;

[0010] S3, determining whether the battery thermal management module shield is exposed to water;

[0011] S4. Control the opening and closing and the opening degree of the automatic shutters of the battery thermal management module shield according to the judgment results of steps S2 and S3.

[0012] Furthermore, the working mode includes:

[0013] In heating mode, the battery thermal management module heats the battery, and the cooling fan of the battery thermal management module is turned off;

[0014] In the self-circulation mode, the battery thermal management module cools the battery through the water cooling system, and the cooling fan is turned off;

[0015] In cooling mode, the battery thermal management module needs to dissipate heat from the water cooling system, and the cooling fan is turned on.

[0016] Furthermore, the step S4 includes:

[0017] S41: If it is determined that the operating mode is the heating mode, the automatic shutters are controlled to close regardless of whether the battery thermal management module shield is exposed to water; the heating mode does not require heat dissipation, so the automatic shutters are closed;

[0018] S42: If it is determined that the operating mode is the self-circulation mode and the battery thermal management module shield is not exposed to water, determine whether the ambient temperature reaches a threshold and take corresponding measures;

[0019] S43: If it is determined that the operating mode is the self-circulation mode and the battery thermal management module shield is exposed to water, controlling the automatic shutter to close; closing the automatic shutter in the event of water can prevent or reduce water from entering the battery thermal management module;

[0020] S44: If it is determined that the operating mode is the cooling mode and the battery thermal management module shield is not exposed to water, the automatic shutter is controlled to open and the opening degree is 100%; the heat dissipation effect is optimal and there is no risk of water ingress;

[0021] S45: If it is determined that the operating mode is the cooling mode and the battery thermal management module shield is exposed to water, perform the following steps:

[0022] S5, sending a reminder of whether to forcibly close the automatic blinds and receiving an interactive signal;

[0023] S6. Control the automatic blinds to perform corresponding operations according to the interactive signal.

[0024] Furthermore, the determining whether the ambient temperature reaches a threshold and taking corresponding measures includes:

[0025] If it is determined that the ambient temperature has reached or exceeded the threshold, the automatic blinds are controlled to open at a first preset opening; in the absence of water ingress risk, the high ambient temperature will accelerate the heating of the water cooling system of the battery thermal management module. Opening the blinds at a certain opening can achieve a certain degree of heat dissipation without turning on the cooling fan, which is energy-saving and environmentally friendly.

[0026] If it is determined that the ambient temperature has not reached the threshold, the automatic blinds are controlled to close.

[0027] Furthermore, the step S6 includes:

[0028] If the interaction signal is identified as not forcibly closing, the automatic blinds are controlled to open at a second preset opening; until the working mode of the battery thermal management module or the water condition changes;

[0029] If the interactive signal is identified as forced closing, the automatic blinds are controlled to close, and steps S2 and S3 are executed again after a preset time, and corresponding measures are taken according to the judgment result.

[0030] Forcibly closing the automatic shutters for a period of time when there is a large amount of water can prevent a large amount of water from submerging the battery thermal management module and causing damage to it.

[0031] Further, step S2 and step S3 are executed again, and corresponding measures are taken according to the judgment result, including:

[0032] According to the judgment results of steps S2 and S3, steps S41 to S44 and the following steps are executed:

[0033] S45′: If it is determined that the working mode is the cooling mode and the battery thermal management module shield is exposed to water, the automatic shutter is controlled to open at a preset second opening; until the working mode of the battery thermal management module or the water exposure condition changes.

[0034] If the temperature of the battery thermal management module is too high, the car will not be able to drive normally, so the automatic blinds need to be opened again after being closed for a period of time.

[0035] Furthermore, after step S1, the method further includes:

[0036] S2': If not, control the automatic blinds to close.

[0037] A battery thermal management module shield is used to implement the above-mentioned battery thermal management module shield control method, including a shield frame, the front end face of the shield frame is provided with an automatic shutter, and a protective net assembly is provided in parallel and opposite to the rear of the automatic shutter. The protective net assembly is detachably connected to the shield frame, the outer side of the shield frame is detachably connected to the shield skin, and the front end of the shield frame is also detachably connected to a water immersion sensor.

[0068] See also Figures 8 and 9As shown, this embodiment also provides a battery thermal management module shield system, including the above-mentioned battery thermal management module shield 1, and also including a shutter controller 2, the shutter controller 2 is electrically connected to the electric push rod 122 and the water immersion sensor 15 respectively, the shutter controller 2 is also electrically connected to the vehicle controller 3, and the vehicle controller 3 is also electrically connected to the ambient temperature sensor 4, the combination instrument 5 and the battery thermal management module 6 respectively.

[0069] See also Figures 1 to 2 As shown, this embodiment also provides a battery thermal management module shield control method, including:

[0070] S1, determining whether the battery thermal management module 6 is in working state;

[0071] S2. If yes, determine the working mode of the battery thermal management module 6;

[0072] S3, determining whether the battery thermal management module shield 1 is exposed to water;

[0073] S4 . Control the opening and closing and the opening degree of the automatic shutter 12 of the battery thermal management module shield 1 according to the judgment results of steps S2 and S3 .

[0074] Specifically, the vehicle controller 3 determines whether the battery thermal management module 6 is in working state. If not, the vehicle controller 3 sends a command to the blinds controller 2, and the blinds controller 2 sends a control signal to the electric push rod 122 to control the automatic blinds 12 to close.

[0075] If so, the vehicle controller 3 determines the working mode of the battery thermal management module 6, and at the same time or subsequently, the water immersion sensor 15 sends a signal to the shutter controller 2, which is then sent to the vehicle controller 3 by the shutter controller 2. The vehicle controller 3 determines whether the battery thermal management module cover 1 is exposed to water based on the signal sent by the shutter controller 2.

[0076] Specifically, the working modes include heating mode, self-circulation mode and cooling mode;

[0077] Heating mode: In a relatively cold environment, the battery thermal management module 6 needs to heat the battery. At this time, there is no need to dissipate heat from the battery thermal management module 6, so the cooling fan of the battery thermal management module 6 is turned off;

[0078] In the self-circulation mode, when the battery temperature rises, the battery thermal management module 6 needs to dissipate heat and cool the battery to prevent it from being too hot. In this case, the water cooling system can meet the cooling requirement. The temperature of the water cooling system itself is not too high, so the cooling fan remains off.

[0079] In cooling mode, the battery temperature continues to rise, and the temperature of the water cooling system itself also gradually rises. At this time, in order to prevent the water cooling system temperature from being too high, the water cooling system needs to be cooled. The cooling fan is turned on, and hot air is blown into the battery thermal management module shield 1. The temperature inside the battery thermal management module shield 1 will also rise immediately.

[0080] In this embodiment, when the battery thermal management module shield 1 is not exposed to water, the vehicle controller 3 determines that the battery thermal management module shield 1 is not exposed to water;

[0081] If the working mode is determined to be the heating mode, the shutter controller 2 controls the automatic shutter 12 to close;

[0082] If the working mode is determined to be the self-circulation mode, the vehicle controller 3 determines whether the ambient temperature has reached a threshold value based on the signal sent by the ambient temperature sensor 4 and takes corresponding measures. In this embodiment, the threshold value is set to 30°C, and different temperature values ​​can also be set according to different vehicle models and geographical locations.

[0083] Specifically, if it is determined that the ambient temperature has reached or exceeded 30°C, the shutter controller 2 controls the automatic shutter 12 to open at a first preset opening; in this embodiment, the first preset opening is 30%, and the opening value can also be adjusted according to actual conditions; if it is determined that the ambient temperature has not reached 30°C, the automatic shutter 12 is controlled to close;

[0084] If the working mode is determined to be the cooling mode, the automatic shutter 12 is controlled to be opened and the opening degree is 100%.

[0085] Example 2, please refer to Figures 1 to 2 As shown, this embodiment provides a battery thermal management module shield control method, which adds method steps for the case where the battery thermal management module shield 1 is exposed to water on the basis of embodiment 1, including:

[0086] S1, determining whether the battery thermal management module 6 is in working state;

[0087] S2. If yes, determine the working mode of the battery thermal management module 6;

[0088] S3, determining whether the battery thermal management module shield 1 is exposed to water;

[0089] S4 . Control the opening and closing and the opening degree of the automatic shutter 12 of the battery thermal management module shield 1 according to the judgment results of steps S2 and S3 .

[0090] Specifically, the vehicle controller 3 determines whether the battery thermal management module 6 is in working state. If not, the vehicle controller 3 sends a command to the blinds controller 2, and the blinds controller 2 sends a control signal to the electric push rod 122 to control the automatic blinds 12 to close.

[0091] If so, the vehicle controller 3 determines the working mode of the battery thermal management module 6, and simultaneously or subsequently the water sensor 15 sends a signal to the shutter controller 2, which is then sent by the shutter controller 2 to the vehicle controller 3. The vehicle controller 3 determines whether the battery thermal management module shield 1 is exposed to water based on the signal sent by the shutter controller 2;

[0092] In this embodiment, when the battery thermal management module shield 1 is exposed to water, the vehicle controller 3 determines that the battery thermal management module shield 1 is exposed to water;

[0093] If the working mode is determined to be the heating mode, the shutter controller 2 controls the automatic shutter 12 to close;

[0094] If the working mode is determined to be the self-circulation mode, the automatic shutter 12 is controlled to close;

[0095] If the working mode is determined to be the cooling mode, the vehicle controller 3 controls the instrument cluster 5 to send a reminder whether to forcibly close the automatic blinds 12; at this time, the user can choose whether to forcibly close the automatic blinds 12;

[0096] Specifically, the user can operate the instrument button to force the automatic shutter 12 to close. The vehicle controller 3 sends a shutter closing instruction to the shutter controller 2. The shutter controller 2 controls the electric push rod 122 to rise, and the automatic shutter 12 closes. The preset closing time can be adjusted according to actual conditions. In this embodiment, the preset time is set to 5 minutes. After 5 minutes, the vehicle controller 3 again determines the working mode of the battery thermal management module 6 and whether it is exposed to water.

[0097] If it is determined that the working mode of the battery thermal management module 6 is the cooling mode and it encounters water, the vehicle controller 3 sends a shutter opening instruction, the shutter controller 2 controls the electric push rod 122 to descend, and the automatic shutter 12 opens at a second preset opening. In this embodiment, the second preset opening is 50%. The second preset opening can also be adjusted according to actual conditions until the working mode of the battery thermal management module 6 or the water situation changes, and then the operation corresponding to the changed working mode and water situation is executed;

[0098] If it is determined that the working mode of the battery thermal management module 6 and the water contact condition are cooling mode and other working conditions other than water contact, the corresponding operation steps are performed according to the current working conditions.

[0099] If the user does not operate the instrument button to force the shutters to close within the determination time, the vehicle controller 3 will determine the interactive signal as not to force closing, and the shutter controller 2 will control the automatic shutters 12 to open at the second preset opening, i.e., 50% opening; until the working mode of the battery thermal management module 6 or the water condition changes, and then perform operations corresponding to the changed working mode and water condition; in this embodiment, the determination time is set to 10s.
