Description

TECHNICAL FIELD

[0002] With the rapid development of new energy vehicles, the number of high-voltage accessories in new energy vehicles is increasing. When the battery in the new energy vehicle provides electric power to the driving motor and various high-voltage accessories in the vehicle, if the total electric power that the battery can provide is low and cannot simultaneously meet the electric power of all high-voltage accessories, it may cause some functions in the vehicle to be unable to be normally used.

Obviously, the described embodiments are only some but not all of the embodiments of the present application.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0058] Embodiment One:

[0059] To facilitate the understanding of the present embodiment, first, a high-voltage accessory power distribution method disclosed by the embodiments of the present application is described in detail. The method is applied to a vehicle controller in a target vehicle, Figure 1 A flow chart of a high-voltage accessory power distribution method provided by an embodiment of the application is shown, as shown in Figure 1 includes the following steps S101-S103:

[0060] S101: Determine the current use scene of the target vehicle.

[0061] In this embodiment, the target vehicle is a new energy vehicle. The use scene includes any one or more of the following: a scene of discharging through a V2L discharging unit, a scene of charging using a charging pile, a scene of cooling the vehicle-mounted battery, and other scenes in addition to the foregoing three scenes.

[0062] For the scenario of discharging externally through the V2L discharging unit, the target vehicle is provided with the V2L discharging unit, and when the target vehicle is in a parking state, a 220V electrical device can be connected to the V2L discharging unit to supply power to the 220V electrical device through the V2L discharging unit. For example, in a camping scenario, a 220V induction cooker can be connected to the V2L discharging unit to supply power to the induction cooker.

[0063] For the scenario of charging using a charging pile, specifically including the scenario of charging the target vehicle using a slow-charging charging pile and the scenario of charging the target vehicle using a fast-charging charging pile. The scenario of cooling the vehicle-mounted battery refers to the scenario that the temperature of the vehicle-mounted battery in the target vehicle is too high and needs to be cooled urgently. The other scenario refers to a scenario other than the three scenarios of discharging externally through the V2L discharging unit, charging using the charging pile, and cooling the vehicle-mounted battery.

[0064] In a possible implementation manner, Figure 2 A flowchart of another method for distributing high-voltage accessory power provided by an embodiment of the present application is shown. Figure 2 As shown in step S101, when determining the current use scenario of the target vehicle, the following steps S1011-S1012 can be performed:

[0065] S1011: Obtain the current working state of each working module corresponding to each use scenario.

[0066] S1012: Determine the current use scenario of the target vehicle according to the working state of each working module.

[0067] In this embodiment, when the use scenario is the scenario of discharging externally through the V2L discharging unit, the working module corresponding to the use scenario can be the V2L discharging unit. When the working state of the V2L discharging unit is working, it means that the V2L discharging unit is discharging externally; when the working state of the V2L discharging unit is not working, it means that the V2L discharging unit is in a non-discharging state. Therefore, in this embodiment, the current use scenario of the target vehicle can be determined according to the working state of the V2L discharging unit. When the working state of the V2L discharging unit is working, the current use scenario of the target vehicle is the scenario of discharging externally through the V2L discharging unit.

[0068] When the use scenario is a scenario of charging by using a charging pile, the working module corresponding to the use scenario can be a charging control module in the target vehicle. When the working state of the charging control module is working, it indicates that the target vehicle is currently charging by using the charging pile. When the working state of the charging control module is not working, it indicates that the target vehicle is not currently charging by using the charging pile. Therefore, in this embodiment, the current use scenario of the target vehicle can be determined according to the working state of the charging control module. Specifically, when the working state of the charging control module is working, the current use scenario of the target vehicle is the scenario of charging by using the charging pile.

[0069] When the use scenario is a scenario of cooling the vehicle battery, the working module corresponding to the use scenario can be a thermal management system in the target vehicle. When the working state of the thermal management system is cooling, it indicates that the vehicle battery is being cooled. When the working state of the thermal management system is not cooling, it indicates that the vehicle battery is not being cooled. Therefore, in this embodiment, the current use scenario of the target vehicle can be determined according to the working state of the thermal management system. Specifically, when the working state of the thermal management system is cooling, the current use scenario of the target vehicle is the scenario of cooling the vehicle battery.

[0070] In this embodiment, when the working state of the V2L discharging unit is not working, it indicates that the current use scenario of the target vehicle is not the scenario of discharging to the outside by using the V2L discharging unit. When the working state of the charging control module is not working, it indicates that the current use scenario of the target vehicle is not the scenario of charging by using the charging pile. When the working state of the thermal management system is not cooling, it indicates that the current use scenario of the target vehicle is not the scenario of cooling the vehicle battery. At this time, it can be determined that the current use scenario of the target vehicle is another scenario.

[0071] S102: Calculate the total power consumption that the target vehicle can provide for each high-voltage accessory in the target vehicle in the use scenario.

[0072] In this embodiment, the high-voltage accessories include a compressor for air conditioning refrigeration, a V2L discharging unit for discharging to the outside, and a PTC (Positive Temperature Coefficient) for heating. The PTC specifically includes a front PTC and a rear PTC. Specifically, the front PTC is used for heating the thermal management system and the front passenger compartment, and the rear PTC is used for heating the rear passenger compartment. In this embodiment, the way of calculating the total power consumption is different in different use scenarios.

[0073] In a possible implementation, when the use-scene is a scenario of discharging externally by the V2L discharging unit, the step S102 of calculating the total power that the target vehicle can currently provide for each high-voltage accessory in the target vehicle under the use-scene can be specifically performed according to the following steps S1021-S1023:

[0074] S1021: According to the available discharging power of the vehicle-mounted battery, the range extender power, the DC converter power, and the power of the V2L discharging unit, a first total power that the target vehicle can currently provide for each high-voltage accessory is calculated.

[0075] Specifically, the first total power that the target vehicle can currently provide for each high-voltage accessory (i.e., all high-voltage accessories) can be calculated by the following formula:

[0076] P1=P R -P Z -P DCDC -P V2L

[0077] wherein P1 represents the first total power, P R represents the available discharging power of the vehicle-mounted battery, P Z represents the range extender power, P DCDC represents the DC converter (DCDC) power, and P V2L represents the power of the V2L discharging unit.

[0078] In this embodiment, when the range extender is in the power generation state, the range extender power is negative; when the range extender is in the starting state, the range extender power is positive; and when the range extender is in the shutdown state, the range extender power is 0.

[0079] S1022: According to the current state of the range extender, a power corresponding to the current state of the range extender is selected from the total vehicle power protection power and the power required by the high-voltage accessory as a second total power that the target vehicle can currently provide for each high-voltage accessory; the total vehicle power protection power is determined by the residual charge capacity of the vehicle-mounted battery.

[0080] In this embodiment, the total vehicle power protection power and the residual charge capacity of the vehicle-mounted battery are in a positive correlation relationship, that is, the more the residual charge capacity of the vehicle-mounted battery, the greater the total vehicle power protection power; and the less the residual charge capacity of the vehicle-mounted battery, the smaller the total vehicle power protection power.

[0081] When the current state of the range extender is the power generation state, the power required by the high-voltage accessories is taken as the second total power consumption that the target vehicle can currently provide for each high-voltage accessory. When the current state of the range extender is the starting state or the shutdown state, the vehicle power consumption protection power is taken as the second total power consumption that the target vehicle can currently provide for each high-voltage accessory.

[0082] In this embodiment, the execution sequence between step S1021 and step S1022 can be that step S1021 is executed first and then step S1022 is executed, or that step S1022 is executed first and then step S1021 is executed, or that steps S1021 and S1022 are executed simultaneously, and the present application does not limit this.

[0083] S1023: Determine the total power consumption as the minimum power consumption between the first total power consumption and the second total power consumption.

[0084] Select the minimum power consumption from the first total power consumption and the second total power consumption as the total power consumption.

[0085] In the second possible implementation, when the vehicle use scenario is a scenario of charging by using a charging pile, the execution of step S102 of calculating the total power consumption that the target vehicle can currently provide for each high-voltage accessory in the target vehicle under the vehicle use scenario can be specifically performed according to the following steps S1024-S1025:

[0086] S1024: Calculate the third total power consumption that the target vehicle can currently provide for each high-voltage accessory according to the available discharge power of the vehicle-mounted battery and the DC converter power.

[0087] In this embodiment, the third total power consumption that the target vehicle can currently provide for each high-voltage accessory can be calculated by the following formula:

[0088] P3=P R -P DCDC

[0089] Wherein, P3 represents the third total power consumption, P R represents the available discharge power of the vehicle-mounted battery, P DCDC represents the DC converter (DCDC) power.

[0090] S1025: Determine the total power consumption according to the minimum power consumption between the vehicle power consumption protection power and the third total power consumption, and the charging power of the charging pile; the vehicle power consumption protection power is determined by the residual charge capacity of the vehicle-mounted battery.

[0091] In this embodiment, the total power consumption can be determined by the following formula:

[0092] P=P C+Min(P3,P Z )

[0093] Where P represents the total power consumption, P Z P3 represents the total power consumption of the vehicle's electrical protection system, and P4 represents the third total power consumption. C This indicates the charging power of the charging station. In this embodiment, when the charging station is a fast charging station, P... C This indicates the charging power of the fast charging station; when the charging station is a slow charging station, P... C This indicates the charging power of the slow charging station.

[0094] In a third possible implementation, when the vehicle usage scenario is for cooling the vehicle battery, when performing step S102 to calculate the total electrical power that the target vehicle can currently provide to each high-voltage accessory in the target vehicle under the vehicle usage scenario, the specific steps are as follows:

[0095] S1026: Based on the available discharge power of the vehicle battery, the power of the range extender, and the power of the DC-DC converter, determine the total electrical power that the target vehicle can currently provide to each high-voltage accessory in the target vehicle.

[0096] In this embodiment, the total power consumption can be determined using the following formula:

[0097] P = P R -P Z -P DCDC

[0098] Where P represents the total power consumption, P R P represents the available discharge power of the vehicle battery. Z P represents the range extender power. DCDC This indicates the power of the DC-DC converter.

[0099] In the fourth possible implementation, when the vehicle usage scenario is another scenario, when performing step S102 to calculate the total electrical power that the target vehicle can currently provide to each high-voltage accessory in the target vehicle under the vehicle usage scenario, the following steps S1027-S10210 can be performed:

[0100] S1027: Determine the first allocable power of the target vehicle based on the available discharge power of the vehicle battery, the power of the range extender, the power of the DC converter, and the drive power of the drive motor in the target vehicle; wherein, when the target vehicle is not currently defrosting or defogging, the first allocable power is determined as the fourth total power; when the target vehicle is currently defrosting or defogging, the maximum power among the first allocable power and the power required for defrosting and defogging is determined as the fourth total power.

[0101] Specifically, the first allocable power consumption can be determined by the following formula:

[0102] P K1 = P R - P Z - P DCDC - P Q

[0103] wherein P K1 represents the first allocable power consumption, P R represents the available discharging power of the on-board battery, P Z represents the power of the range extender, P DCDC represents the power of the DC converter (DCDC), and P Q represents the driving power corresponding to the driving motor in the target vehicle.

[0104] P Q = MIN(P Q1 , P Q2 )

[0105] P Q1 represents the driving power required by the driving motor in the target vehicle, P Q2 is the driving power to be allocated, specifically the driving power to be allocated to the driving motor in the target vehicle. Wherein P Q2 is less than P R - P Z - P DCDC , P R - P Z - P DCDC , the greater P Q2 is, the greater P W is.

[0106] The target vehicle is currently not defrosting and demisting, indicating that the target vehicle currently has no defrosting and demisting demand, at this time, the first allocable power consumption is directly determined as the fourth total power consumption. The target vehicle is currently defrosting and demisting, indicating that the target vehicle has defrosting and demisting demand, at this time, the fourth total power consumption can be determined by the following formula:

[0107] P4 = Max(P W , P K1 )

[0108] wherein P4 represents the fourth total power consumption, P W represents the power required for defrosting and demisting, and P K1 represents the first allocable power consumption.

[0109] S1028: According to the current state of the range extender, select the power corresponding to the current state of the range extender from the vehicle power protection power and the high-voltage accessory required power as the fifth total power that the target vehicle can currently provide to each high-voltage accessory. The vehicle power protection power is determined by the remaining charge capacity of the vehicle-mounted battery.

[0110] In this embodiment, when the current state of the range extender is the power generation state, the high-voltage accessory required power is taken as the fifth total power that the target vehicle can currently provide to each high-voltage accessory. When the current state of the range extender is the start state or the shutdown state, the vehicle power protection power is taken as the fifth total power that the target vehicle can currently provide to each high-voltage accessory.

[0111] S1029: According to the current state of the range extender, select the power corresponding to the current state of the range extender from the second allocable power and the high-voltage accessory required power as the sixth total power that the target vehicle can currently provide to each high-voltage accessory. The second allocable power is determined according to the available discharge power of the vehicle-mounted battery, the range extender start power, and the DC converter power.

[0112] In this embodiment, the second allocable power can be determined by the following formula:

[0113] P K2 = P R -P ZQ -P DCDC

[0114] wherein P K2 represents the second allocable power, P R represents the available discharge power of the vehicle-mounted battery, P ZQ represents the range extender start power, and P DCDC represents the DC converter (DCDC) power.

[0115] When the current state of the range extender is the start state, the second allocable power is taken as the sixth total power that the target vehicle can currently provide to each high-voltage accessory. When the current state of the range extender is the shutdown state or the power generation state, the high-voltage accessory required power is taken as the sixth total power that the target vehicle can currently provide to each high-voltage accessory.

[0116] S10210: Select the minimum power from the fourth total power, the fifth total power, and the sixth total power as the total power.

[0117] S103: According to the priority order of each high-voltage accessory in the vehicle use scenario, distribute the total power to each high-voltage accessory.

[0118] Each high-voltage accessory works based on the allocated power consumption.

[0119] In the embodiments of the application, when the vehicle use scenario is a scenario of discharging externally through a V2L discharging unit, the priority order of each high-voltage accessory in the vehicle use scenario is: V2L discharging unit and compressor > thermistor, specifically, V2L discharging unit and compressor > front thermistor > rear thermistor.

[0120] When the vehicle use scenario is a scenario of charging using a charging pile or a scenario of cooling the vehicle-mounted battery or other scenarios, the priority order of each high-voltage accessory in the vehicle use scenario is: compressor > thermistor, specifically, compressor > front thermistor > rear thermistor.
