[0045] The technical solutions in the embodiments of the present application will be described clearly below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0047] The vehicle mute charging control method provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0048] As shown in Figure 1 The vehicle mute charging control method applied to the vehicle end provided by the embodiments of the present application includes the following steps:

[0049] Step S1, acquiring a mute charging period,

[0050] The mute charging period is the time period when the noise has the greatest impact on the residents near the user's residence. The mute charging period can be any period set by the user; or it can be set based on the work and rest information of the residents in the surrounding environment to reduce the disturbance to the residents in the surrounding environment.

[0051] Step S2, acquiring a current time of starting charging and a first parameter corresponding to the current time, the first parameter including an environmental temperature, a battery temperature and a battery state of charge SOC,

[0052] As shown in Figure 2 When the user charges at the residence, most of the time is AC slow charging. Through the AC high-voltage harness, the AC charging pile outputs AC power to the on-board charger, and through the DC high-voltage harness, the on-board charger converts the AC power output by the AC charging pile into DC power and charges into the power battery. In the process of AC conversion to DC, the on-board charger will heat up, and the battery will also generate heat during charging, thereby increasing the environmental temperature and the battery temperature. When the temperature rises to a certain extent, the heat is dissipated by starting the exchanger, compressor and electronic fan through the cooling circuit. The environmental temperature represents the temperature in the space near the vehicle end at the current time, the battery temperature represents the temperature of the battery at the current time, and the battery SOC represents the current remaining capacity of the battery.

[0053] Step S3, determining a temperature rise value of each time in the mute charging period based on the first parameter and the current time,

[0054] In the case that the output power of the AC charging pile is constant, the charging time of the battery can be determined based on the battery SOC, and the charging time of the battery, in combination with the ambient temperature and the battery temperature at the current time, determines the temperature rise value that continuously increases with the increase of the charging time, so as to predict the temperature rise value at each time in the silent charging period, and the corresponding ambient temperature and battery temperature.

[0055] In step S4, based on the current time, the silent charging period, and the temperature rise value at each time in the silent charging period and the preset temperature rise value, the heat dissipation mode of the vehicle end is controlled to achieve silent charging in the silent charging period. The charging time required for the battery to be fully charged can be determined according to the battery SOC, and the temperature rise value of each period in the vehicle charging process can be determined in combination with the current time and the ambient temperature and battery temperature at the current time. Therefore, the temperature rise value at each time in the silent charging period can also be known, and the temperature rise value at each time in the silent charging period is compared with the preset temperature rise value, and the heat dissipation mode of the vehicle end is controlled according to the comparison result. The preset temperature rise value is determined by the temperature threshold of the vehicle end components.

[0056] It can be understood that the temperature rise value increases with time, and if the temperature rise value is greater than the preset temperature rise value in the silent charging period, the heat dissipation mode of the vehicle end has to be controlled to a heat dissipation mode with stronger heat dissipation effect in order to protect the safety of the vehicle end, and the heat dissipation mode with stronger heat dissipation effect will bring greater noise and affect the surrounding environment. Therefore, the heat dissipation mode of the vehicle end can be controlled to a heat dissipation mode with stronger heat dissipation effect before the silent charging period to reduce the increasing rate of the temperature rise value, so that the temperature rise value in the silent charging period is less than the preset temperature rise value, and at this time, the heat dissipation mode of the vehicle end is controlled to a heat dissipation mode with smaller noise to achieve silent charging of the vehicle in the silent charging period and reduce the noise impact of vehicle charging.

[0057] The charging control method of the vehicle provided by the embodiments of the present application can determine the temperature rise value at each time in the silent charging period by the silent charging period, the current time of starting charging, and the first parameter corresponding to the current time such as the ambient temperature, the battery temperature, and the battery SOC, compare the temperature rise value at each time in the silent charging period with the preset temperature rise value, and control the heat dissipation mode of the vehicle end according to the comparison result to achieve silent charging in the silent charging period and reduce the noise impact of vehicle charging.

[0058] Optionally, the heat dissipation mode includes a silent heat dissipation mode and a noise heat dissipation mode, and the vehicle end includes a circulating water circuit, a compressor, and a fan; and the control of the heat dissipation mode of the vehicle includes:

[0059] controlling the circulating water circuit to be in an operating state, the compressor and the fan to be in a stopped operating state, so that the vehicle end is in the quiet heat dissipation mode, or reducing the charging power so that the vehicle end is in the quiet heat dissipation mode;

[0060] controlling the circulating water circuit, the compressor and the fan to be in an operating state, so that the vehicle end is in the noise heat dissipation mode.

[0061] The thermal management controller of the vehicle end collects the battery temperature, the circulating water temperature and the on-board charger temperature through multiple temperature sensors, and can control the start and stop and the rotating speed of the water pump and the compressor, and can also control the start and stop and the rotating speed of the electronic fan according to the pressure difference formed by the compressor.

[0062] The charging scene of the vehicle is mostly that the user returns to the residence to charge after work. Figure 3 As shown in the figure, when charging, the on-board charger (OBC) converts alternating current into direct current and generates heat, and the internal temperature rises. During the charging process of the battery, heat is generated by the internal resistance of the battery, and the temperature continuously rises. When the thermal management controller of the vehicle end detects the cooling demand input of any one of the battery management system (BMS) and the OBC, the thermal management controller issues an instruction to start the water pump to reduce the temperature of the circulating water circuit. When the circulating water circuit cannot meet the cooling demand, the thermal management controller issues an instruction to start the compressor. After the compressor starts, a pipeline pressure difference is gradually generated. When the pressure difference value reaches a certain value, the thermal management controller issues a start instruction to the electronic fan. Due to the effect of the electronic fan, the condenser can be controlled.

[0063] According to the data analysis of the vehicle, the noise generated by the water pump, the compressor and the electronic fan at different rotating speeds is different, but the noise of the electronic fan is the largest, and it is the largest noise source at each rotating speed. When the noise value is greater than 60 dB, the noise is at a noisy level. Therefore, the preset temperature rise value can be the temperature rise value when the corresponding electronic fan is started, or the temperature rise value when the corresponding compressor is started. Preferably, the temperature rise value corresponding to the start of the compressor is determined as the preset temperature rise value, which further reduces the noise influence of the vehicle charging.

[0064] The vehicle end is in a noise-free cooling mode when the temperature rise value corresponding to the start of the compressor is the preset temperature rise value, the circulating water circuit of the vehicle end is in an operating state, and the compressor and the fan are in a stopped operating state; and the vehicle end is in a noise cooling mode when the circulating water circuit of the vehicle end and the compressor are in an operating state, and the fan is in a stopped operating state or the circulating water circuit, the compressor and the fan are in an operating state. It should be noted that reducing the charging power will increase the charging time, but the temperature rise value will increase at a slower rate, the cooling demand will decrease accordingly, and the noise generated by cooling will also decrease. Therefore, when the charging power is reduced, the vehicle end is also in a noise-free cooling mode. According to different situations, the vehicle end is controlled to enter different cooling modes, which is more flexible to use.

[0065] Optionally, in the case where the current time is before the noise-free charging time period,

[0066] Step S4, based on the current time, the noise-free charging time period, the temperature rise value of each time in the noise-free charging time period and the preset temperature rise value, the cooling mode of the vehicle end is controlled, comprising:

[0067] When the temperature rise value of any time in the noise-free charging time period is greater than or equal to the preset temperature rise value, the cooling mode of the vehicle end in the first time period is controlled to be the noise cooling mode; in the noise-free charging time period, the circulating water circuit is in an operating state, and the compressor and the fan are in a stopped operating state; wherein the first time period is the time period between the current time and the noise-free charging time period,

[0068] In the case where the current time at which the vehicle end starts charging is before the noise-free charging time period, the current time and the noise-free charging time period can use the noise cooling mode with larger noise and better cooling effect, or the noise-free cooling mode with smaller noise and poorer cooling effect.

[0069] When the temperature rise value of any time in the noise-free charging time period is greater than or equal to the preset temperature rise value, the noise-free cooling mode will have to be started in the noise-free charging time period to avoid damage to the vehicle end due to high temperature. Therefore, the cooling mode of the vehicle end is controlled to be the noise cooling mode in the first time period in advance, so as to reduce the growth rate of the temperature rise value of the vehicle end in the first time period, so that the vehicle end will not have a temperature rise value greater than the preset temperature rise value after entering the noise-free charging time period, so as to ensure that the vehicle end is in the noise-free cooling mode with the circulating water circuit in an operating state and the compressor and the fan in a stopped operating state in the noise-free charging time period, and reduce the influence of noise on the surrounding environment.

[0070] When the temperature rise value at all time points in the silent charging period is less than the preset temperature rise value, the vehicle end is controlled to keep the circulating water circuit in the running state and the compressor and the fan in the stop running state in the first time period and in the silent charging period.

[0071] When the temperature rise value at all time points in the silent charging period is less than the preset temperature rise value, it indicates that the vehicle end can adopt the silent heat dissipation mode in the silent charging period, and can adopt the silent heat dissipation mode or the noise heat dissipation mode in the first time period. Preferably, the silent heat dissipation mode of keeping the circulating water circuit in the running state and the compressor and the fan in the stop running state is adopted in the first time period and in the silent charging period, so as to further reduce the noise influence of vehicle charging. It should be noted that after the silent charging period, with the increase of charging time, the temperature rise value may reach the preset temperature rise value, so the noise heat dissipation mode needs to be started for the protection of the vehicle. Since the period is not in the silent charging period, even if noise is generated, it will not cause great influence on the surrounding environment.

[0072] In the case that the previous time point is located before the silent charging period, the heat dissipation mode of the vehicle end is flexibly controlled according to the relationship between the temperature rise value in the silent charging period and the preset temperature rise value, so as to take into account the protection of the vehicle end and the reduction of noise influence.

[0073] Optionally, in the case that the current time point is located in the silent charging period,

[0074] Step S4, based on the current time point, the silent charging period, the temperature rise value at each time point in the silent charging period and the preset temperature rise value, the heat dissipation mode of the vehicle end is controlled, including:

[0075] When the temperature rise value at all time points in the second time period is less than the preset temperature rise value, the circulating water circuit is controlled to be in the running state and the compressor and the fan are controlled to be in the stop running state in the second time period, wherein the second time period is a time period between the current time point and an ending time point of the silent charging period,

[0076] In the case that the current time point is located in the silent charging period, the heat dissipation mode of the vehicle end needs to be controlled according to the relationship between the temperature rise value at each time point in the silent charging period and the preset temperature rise value, so as to take into account the reduction of noise influence and the protection of the vehicle end.

[0077] When the temperature rise value of all time points in the second time period is less than the preset temperature rise value, the protection of the vehicle end does not need to be considered, and the vehicle end is controlled to keep the circulating water circuit in the running state and the compressor and the fan in the stop running state in the silent heat dissipation mode in the second time period. It should be noted that after the silent charging time period, the temperature rise value will increase with the increase of the charging time, and when the temperature rise value is equal to or greater than the preset temperature rise value, the noise heat dissipation mode with better heat dissipation effect needs to be started to protect the vehicle end.

[0078] When the temperature rise value of the target time point in the second time period is greater than or equal to the preset temperature rise value, in the first sub time period, the circulating water circuit is controlled to be in the running state, and the compressor and the fan are controlled to be in the stop running state; and in the second sub time period, the heat dissipation mode of the vehicle end is controlled to be the noise heat dissipation mode.

[0079] The first sub time period is the time period between the current time point and the target time point, and the second sub time period is the time period between the target time point and the end time point of the silent charging time period.

[0080] When the temperature rise value of the target time point in the second time period is greater than or equal to the preset temperature rise value, the temperature rise value before the target time point is less than the preset temperature rise value, and therefore the protection of the vehicle end does not need to be considered, and in the first sub time period, the circulating water circuit is controlled to be in the running state and the compressor and the fan are controlled to be in the stop running state in the silent heat dissipation mode. After the target time point, the temperature rise value is greater than or equal to the preset temperature rise value, and the heat dissipation mode of the vehicle end in the second sub time period is controlled to be the noise heat dissipation mode with better heat dissipation effect to protect the vehicle end.

[0081] In the case that the current time point is located in the silent charging time period, the heat dissipation mode of the vehicle end is flexibly controlled according to the relationship between the temperature rise value of each time point in the silent charging time period and the preset temperature rise value, so as to balance the reduction of noise influence and the protection of the vehicle end.

[0082] Optionally, in the case that the current time point is located after the silent charging time period, before step S4, the method further comprises:

[0083] sending first information to the user end, the first information including the expected charging completion time and confirmation information whether to enter the silent heat dissipation mode,

[0084] The first information includes the expected charging completion time and the confirmation information whether to enter the silent heat dissipation mode, and the expected charging completion time is determined based on the battery SOC and the charging power of the charging pile.

[0085] receiving second information sent by the user terminal, the second information including a request for entering the silent heat dissipation mode or not,

[0086] After receiving the first information, the user determines the time when the charging is completed according to the current time and the estimated time when the charging is completed, and sends second information to the vehicle terminal according to the user's own needs.

[0087] Based on the second information, it is determined whether to reduce the charging power.

[0088] If the user thinks that the time when the charging is completed meets the user's own needs, the user sends a request to the vehicle terminal to reduce the charging power. Although the total charging time increases, the growth rate of the temperature rise value decreases, the required heat dissipation effect also decreases, and the noise generated by the heat dissipation also decreases. If the user thinks that the charging is too slow and the time when the charging is completed cannot meet the user's own needs, the user sends a request to the vehicle terminal not to reduce the charging power. When the temperature rise value is greater than or equal to the preset temperature rise value, the heat dissipation mode of the vehicle terminal is controlled to the noise heat dissipation mode to protect the vehicle. The heat dissipation mode of the vehicle can be flexibly controlled according to the user's needs, and the user experience is improved.

[0089] As shown in Figure 4 In an alternative embodiment, after the vehicle starts charging, the silent charging period, the current time when the charging starts, and the first parameter corresponding to the current time are obtained. According to the silent charging period, the current time and the corresponding first parameter, the temperature rise value of the silent charging period can be determined. In the case that the current time is before the silent charging period, if the temperature rise value of any time in the silent charging period is equal to or greater than the preset temperature rise value, the vehicle starts the noise heat dissipation mode in the first time period in advance, and starts the silent heat dissipation mode in the silent charging period; if the temperature rise value of any time in the silent charging period is not equal to or greater than the preset temperature rise value, the vehicle maintains the silent heat dissipation mode in the first time period and the silent charging period.

[0090] In the case that the current time is within the silent charging period, if the temperature rise value of the target time in the silent charging period is equal to or greater than the preset temperature rise value, the vehicle starts the silent heat dissipation mode in the first sub-time period and starts the noise heat dissipation mode in the second sub-time period; if the temperature rise value of the target time in the silent charging period is not equal to or greater than the preset temperature rise value, the vehicle maintains the silent heat dissipation mode in the second time period.

[0091] In the case that the current time is after the silent charging period, the vehicle terminal sends the first information to the user terminal, and the vehicle terminal receives the second information sent by the user terminal. The vehicle terminal determines whether to reduce the charging power according to the second information.

[0092] Optionally, the method further comprises:

[0093] When the vehicle end keeps the silent heat dissipation mode during the silent charging period, the silent charging setting success information is sent to the user end. The user can adjust the silent charging period and the heat dissipation mode according to the number of received silent charging setting success information, for example, assuming that the user sets the silent charging period to 1 a.m. to 3 a.m. for the first time, and only receives 5 times of silent charging setting success information in a month, it indicates that the current heat dissipation mode cannot well realize the silent charging during the first set silent charging period, and the user can correspondingly increase the operation power of each heat dissipation component during the heat dissipation and adjust the silent charging period, such as adjusting to 0 a.m. to 2 a.m. The user's use experience is further enhanced.

[0094] Optionally, in step S3, the temperature rise value of each time in the silent charging period is determined based on the first parameter and the current time, including:

[0095] The charging duration is determined based on the battery SOC;

[0096] The temperature rise value change data is determined based on the ambient temperature, the battery temperature and the charging duration;

[0097] The temperature rise value of each time in the silent charging period is determined based on the current time and the temperature rise value change data.

[0098] The charging power of the charging pile is obtained, and the charging duration can be determined in combination with the battery SOC indicating the remaining power of the battery. Based on the charging duration, the temperature rise value changing with the charging duration, i.e., the temperature rise value change data, can be determined in combination with the battery temperature at the current time, the ambient temperature at the current time and the heat amount of the main heat generating component such as the battery charging heat amount. According to the current time and the temperature rise value change data corresponding to the charging duration, the temperature rise value of each time during the charging process is determinable, and therefore, the temperature rise value of each time in the silent charging period can be determined. The temperature rise value of each time in the silent charging period is determined based on the battery SOC, the ambient temperature and the battery temperature, which ensures the accuracy of the temperature rise value.

[0099] The vehicle silent charging control method provided by the embodiment of the application can be executed by the vehicle silent charging control device. In the embodiment of the application, the vehicle silent charging control method is executed by the vehicle silent charging control device, and the vehicle silent charging control device is described in combination with the accompanying drawings.
