Fig. 2 is a flowchart of a control method of a thermal management system according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps: step S1: acquiring working condition information of the electric automobile, wherein the working condition information comprises at least one of the following: the system comprises an ambient temperature, the temperature of a power battery, a parking charging air conditioner, a driving air conditioner and a driving air conditioner. Step S2: and controlling the thermal management system to execute a target heat exchange mode in response to the condition information meeting the preset condition, wherein the target heat exchange mode comprises at least one of the following modes: a power battery heating mode and a passenger compartment heating mode. Step S3: generating a control instruction set based on the working condition information and the target heat exchange mode of the thermal management system, wherein the control instruction set is used for controlling the preset heat exchange elements to be turned on or turned off, and the preset heat exchange elements comprise at least one of the following components: the device comprises a positive temperature coefficient thermistor, a heat pump air conditioning system, a motor system, a seat heating sheet and a power battery heating sheet.
It should be noted that the motor system can heat the passenger compartment and the power battery through the blocking heat and the residual heat of the motor, wherein the motor system is controlled to perform the blocking heat according to the situation only when the vehicle stops charging, and when the vehicle normally runs, the motor system is used for driving the vehicle to run without performing the blocking control. The turning on or off of the motor system in the above control method refers to the locked rotor heat generation of the motor system. Wherein, the thermal management system can simultaneously execute a passenger compartment heating mode and a power battery heating mode.
In this embodiment, the thermal management system is controlled to execute the target heat exchange mode by judging the working condition information of the electric vehicle, and the preset heat exchange element is started according to the target heat exchange mode. The thermal management system is in a power battery heating mode, the preset heat exchange elements are controlled to be opened or closed in real time along with the change of working condition information, the corresponding preset heat exchange elements are opened according to the working condition information, and power consumption is reduced on the basis of increasing the heating speed of the battery and shortening charging time. The heat management system is in a heating mode of the passenger compartment, the opening and closing of the preset heat exchange elements are controlled in real time along with the change of the working condition information, the corresponding preset heat exchange elements are opened according to the working condition information, and the preset heat exchange elements with lower power consumption are selected to heat the passenger compartment, so that the heating power consumption of the low-temperature cab is reduced, and the low-temperature endurance mileage is improved.
Optionally, in step S2, in response to the operating condition information meeting the preset condition, controlling the thermal management system to execute a target heat exchange mode, including: comparing the temperature of the power battery with a preset battery temperature; under the condition that the temperature of the power battery is lower than the preset battery temperature, judging whether the electric automobile is in a state that a parking charging air conditioner is started or a parking charging air conditioner is closed; and if so, controlling the thermal management system to execute the power battery heating mode. In the above steps, the power battery is heated to a proper temperature before low-temperature charging, so that the charging time can be shortened.
Optionally, in step 3, a control instruction set is generated based on the operating condition information and the target heat exchange mode in which the thermal management system is located, where the control instruction set is used to control the preset heat exchange element to be turned on or off, and includes: under the condition that the electric automobile is stopped, the charging air conditioner is turned off, whether the temperature of the power battery is larger than a second temperature threshold value and smaller than a first temperature threshold value or not is judged; if yes, generating a first target instruction in the control instruction set, wherein the first target instruction is used for controlling the heat pump air conditioning system and the motor system to be closed and keeping the power battery heating plate to be continuously started. In the above steps, when the temperature of the power battery rises to a certain temperature, the heat pump air conditioning system and the motor system are shut down to reduce the power consumption of the battery.
Optionally, in step 3, a control instruction set is generated based on the operating condition information and the target heat exchange mode in which the thermal management system is located, where the control instruction set is used to control the preset heat exchange element to be turned on or off, and includes: under the condition that the electric automobile is stopped, the charging air conditioner is turned off, whether the temperature of the power battery is smaller than a first temperature threshold value or not is judged; and if so, generating a second target instruction in the control instruction set, wherein the second target instruction is used for controlling the motor system to be closed, and the positive temperature coefficient thermistor and the power battery heating sheet to be opened. In the steps, the power battery is heated by the positive temperature coefficient thermistor and the power battery heating sheet all the time because the blocked rotation of the motor system generates large heat and energy consumption.
Optionally, in response to the condition information meeting the preset condition, controlling the thermal management system to execute a target heat exchange mode, including: and judging whether the electric automobile is in a working condition of starting a parking charging air conditioner or starting a driving air conditioner, and if so, controlling the thermal management system to execute a heating mode of the passenger compartment.
Optionally, in step S3, based on the operating condition information and the target heat exchange mode of the thermal management system, a control instruction set is generated, where the control instruction set is used to control the preset heat exchange elements to be turned on or off, and includes: under the condition that the electric automobile is in a driving air conditioner starting working condition, judging whether the environment temperature is in a first preset temperature range or not; and if so, generating a third target instruction in the control instruction set, wherein the third target instruction is used for controlling the opening of the positive temperature coefficient thermistor and the seat heating sheet. Wherein, the value range of the first preset temperature interval is generally less than or equal to-10 ℃.
In the above step, the temperature rise of the passenger compartment is slower in the lower temperature interval. Because the energy consumption of the positive temperature coefficient thermistor is low, under the working condition of low environmental temperature, the positive temperature coefficient thermistor consumes less energy of the battery, so that the positive temperature coefficient thermistor is started to heat the passenger compartment to improve the heating rate.
Optionally, in step S3, based on the operating condition information and the target heat exchange mode of the thermal management system, a control instruction set is generated, where the control instruction set is used to control the preset heat exchange elements to be turned on or off, and includes: judging whether the ambient temperature is in a second preset temperature range or not under the condition that the electric automobile is in the driving air conditioner starting state; if yes, a fourth target instruction in the control instruction set is generated, and the fourth target instruction is used for controlling the heat pump air conditioning system to be closed and the seat heating sheet to be opened. Wherein the value range of the second preset temperature interval is generally less than or equal to-10 ℃.
In the above steps, the heat pump air conditioning system has higher power consumption than the seat heater sheet. Especially, under the condition of low temperature, the battery power can be greatly reduced by starting the heat pump air conditioning system, and the endurance mileage is seriously influenced, so that under the condition of low ambient temperature, the heat pump air conditioning system is closed, and only the seat heating sheet is used for heating the passenger compartment.
Optionally, in step S3, based on the operating condition information and the target heat exchange mode of the thermal management system, a control instruction set is generated, where the control instruction set is used to control the preset heat exchange elements to be turned on or off, and includes: under the condition that the heat management system is controlled to execute a heating mode of the passenger compartment, judging whether a person is seated on a seat in the passenger compartment; if yes, generating a fifth target instruction in the control instruction set, wherein the fifth target instruction is used for controlling the seat heating sheet to be started. In the steps, the seat heating sheets at the corresponding positions are turned on according to the conditions of passengers, so that the energy consumption is low.
