Description

Room and battery temperature management method of electric vehicle

The present invention relates to a temperature management method for charging an electric vehicle, and more particularly, to maximize the battery charging efficiency and initial discharging efficiency of an electric vehicle while reducing the electric load of the cooling system at the beginning of the electric vehicle. It relates to room temperature and battery temperature management method.

Today, internal combustion engine (engine) vehicles using fossil fuels have many problems such as environmental pollution caused by exhaust gas, global warming caused by carbon dioxide, and respiratory diseases caused by ozone generation.

And because fossil fuels on Earth are so limited, they are in danger of becoming exhausted someday.

Accordingly, development of eco-friendly electric vehicles (EVs) that use an electric motor as a driving source has been actively progressed.

In addition to the electric motor for driving the vehicle, the electric vehicle is equipped with a battery for supplying power to the electric motor, which is driven after charging the battery from an external charging device before driving.

Also, as is well known, the cruising distance (one-charging mileage) is very important in the electric vehicle due to the limitation of the energy accumulation density of the battery.

In particular, when the cooling system is operated, a lot of power is consumed due to the operation of the compressor and the air conditioning blower, and the maximum range may be reduced by up to 50% when compared to the range without the operation.

Therefore, the reduction of electric load of the cooling system is very important for increasing the range, and the range may be increased by approximately 40% or more when the power consumption of the cooling system is reduced by 33%.

In addition, the charging / discharging efficiency varies greatly depending on the temperature of the battery cell. If the temperature of the battery cell is too high or too low during battery charging, energy may not accumulate well (decrease in charging efficiency).

Therefore, there is a need for a method of reducing electric load of the cooling system at the beginning of operation while maximizing charging efficiency and initial discharge efficiency during battery charging.

In the past, the temperature management of the car was limited only to the indoor temperature control in consideration of the comfort of the vehicle interior, and the battery charging efficiency, the initial discharge efficiency, the cruising distance after charging, the electric load at the beginning of operation, the operating amount of the cooling system, etc. Temperature management took place without further consideration.

Accordingly, the present invention has been made in consideration of the above problems, and can maximize the battery charging efficiency and initial discharge efficiency of an electric vehicle and reduce the electrical load of the cooling system at the beginning of operation, thereby accumulating the energy accumulation density of the battery. The purpose of the present invention is to provide a method of managing the indoor temperature and battery temperature of an electric vehicle that can increase the range while maximizing the range.

In order to achieve the above object, the present invention comprises the steps of (a) requesting a remote cooling operation to the vehicle by the user operating the terminal while the vehicle battery is being charged by the external charging device; (b) checking, by the controller, the battery SOC when the wireless communication terminal of the vehicle receives the remote cooling operation request and transmits the request to the controller; (c) calculating a indoor heat load and determining a target set temperature from the calculated indoor heat load if the battery SOC satisfies a condition that is equal to or greater than a reference SOC value; (d) then operating and controlling the cooling system such that the room temperature reaches and maintains the target set temperature; (E) controlling the operation of the battery cooling system during the operation of the cooling system to manage the battery temperature provides a method for temperature management when charging an electric vehicle.

Here, the temperature management method of the present invention, the battery control by controlling the operation of the battery cooling system according to the battery temperature collected in real time while the vehicle battery is charged by the external charging device before the step (a) to manage the battery temperature Characterized in that it further comprises a forced management mode step.

In addition, the temperature management method of the present invention, the step of calculating the operating time of the cooling system by the control unit receiving the reserved operating time when the user reserves the starting time by operating the terminal while the vehicle battery is being charged by the external charging device Wow; After that, when the operation time of the cooling system, the control unit (b) to perform the step (e) separately; characterized in that it further comprises.

Accordingly, according to the temperature management method of the electric vehicle according to the present invention, by controlling the pre-cooling and controlling the battery temperature of the vehicle at the same time as the remote or scheduled start time while charging the vehicle battery, the battery charge / discharge By increasing the efficiency, it is possible to increase the range of the electric vehicle.

In addition, it is possible to provide a comfortable indoor environment when the passengers ride by pre-operation of the cooling system according to the remote or departure operation time while charging, and to reduce the power consumption by the cooling system during driving, thereby increasing the range.

The present invention relates to a temperature management method of an electric vehicle, and in particular, it is possible to maximize the battery charging efficiency and the initial discharge efficiency of the electric vehicle and to reduce the electrical load of the cooling system at the beginning of operation, thereby limiting the energy accumulation density of the battery. It is to provide a method of managing the indoor temperature and battery temperature of the electric vehicle that can increase the range while maximizing the range.

In order to achieve the above object, in the present invention, the concept of remote and pre-cooling control during the charging is introduced, when the vehicle battery is fully charged by an external charging device, but not while the vehicle is running, the air conditioning system (remote control or reservation method) By cooling) and battery cooling system (for battery temperature management) to cool the room temperature to a comfortable temperature before driving and maximize the charging efficiency and discharge efficiency at the beginning of operation. Will be managed.

At this time, since the cooling system and the battery cooling system are operated remotely or by reservation while charging the battery by connecting the external charging device to the vehicle, it is consumed when the cooling system and the battery cooling system are operated (remote or reserved (pre) operation). The power is supplied by the external charging device, not the vehicle battery.

1 is a block diagram showing a remote control system for implementing a temperature management method according to the present invention, prior to explaining the temperature management method according to the present invention of a system that can remotely control the cooling system and the battery cooling system The configuration will be described.

As shown, the electric vehicle 10 is equipped with a wireless communication terminal 11 for performing communication through a central server 20 outside the vehicle and a wireless communication network such as a mobile communication network (eg, 3G) or a wireless Internet network. .

The wireless communication terminal 11 is a communication means for communication between the control unit in the electric vehicle 10, that is, the control unit performing the control process of the present invention and a user (driver) in a remote location outside the vehicle.

In addition, a user may use a terminal 31 such as a computer (accessible) that can be connected to the central server 20 through a wired / wireless internet network, or use a wireless communication network such as a mobile communication network (3G) or a wireless internet network. A mobile communication terminal 32 connectable (communicable) with the server 20 is used.

The control unit includes a communication controller 12 connected to the wireless communication terminal 11 of the vehicle, a charging controller 13 for controlling the in-vehicle charging device in connection with battery charging, and an air conditioning system. Air conditioner controller 14 for controlling, the battery controller 15 for collecting the battery status related information and controls the operation of the battery cooling system, etc. can be configured, these multiple controllers through the cooperative control of the present invention It can be set to perform the control process of, that is, the integrated control process of the cooling system and the battery cooling system.

The air conditioning controller 14 collects room temperature, outside temperature, insolation, and evaporator temperature information from each sensor of the vehicle, and controls the overall operation of the air conditioning system (including the cooling system).

That is, it controls the operation of various doors (temperature control doors, internal and external doors, mode control doors, etc.) of the air conditioning system, and controls the operation of the compressor and the air conditioning blower of the cooling system.

The battery controller 15 collects battery temperature information from a temperature sensor installed in a cell in real time, monitors a state of charge (SOC), and a cooling blower and a rear discharge fan of a battery cooling system for battery temperature management. It will control the operation of.

In addition, the charge controller 13 is shared with the air conditioning controller 14 and the battery controller 15 while exchanging various information related to the control, basically receiving the indoor temperature, outside temperature, solar radiation information, etc. from the air conditioning controller 14 In addition, the battery controller 15 receives battery related information such as a battery SOC.

Here, the rear extractor fan is for discharging air cooled through the battery to the outside of the vehicle.

As a result, the above configuration allows the user to remotely request the operation of the remote cooling and the scheduled cooling described later through the communication network, and to set and change various items related to the control.

On the other hand, in the present invention, a remote control process during battery charging, the process of controlling the room temperature to the set temperature, the control process of maintaining the room temperature to the set temperature, the process of managing and controlling the battery temperature is in progress.

In the process of controlling the indoor temperature to the set temperature, it is necessary to minimize the energy consumption by optimizing the indoor temperature arrival time during the initial operation.To do this, the airflow of the air conditioning blower is controlled to be linked to the operation amount of the compressor to minimize the indoor temperature arrival time. do.

In addition, in the control process of maintaining the indoor temperature, the power consumption generated when maintaining the temperature should be minimized by optimizing the compressor operation amount and the air volume control when the indoor temperature is close to the target set temperature. Turn off the compressor and run the HVAC blower at the minimum.

2 and 3 are flowcharts illustrating a method for managing room temperature and battery temperature according to the present invention, and a process of pre-cooling and controlling a room temperature of a vehicle according to a remote or scheduled start time during battery charging and simultaneously managing battery temperature. According to the series of control procedures shown, it is possible to increase the charging / discharging efficiency of the battery to increase the range of the electric vehicle.

In other words, it provides a comfortable indoor environment for passengers by pre-operating the cooling system according to the remote or departure operation time while charging, and also increases the range by reducing the battery power consumption by the air conditioning system (air conditioning system) while driving. .

In addition, the charging / discharging efficiency of the battery is sensitively changed according to the temperature of the battery cell. Therefore, by using the pre-cooled indoor air, the battery temperature is optimally managed during the battery charging by the external charging device, thereby improving the battery charging efficiency. At the same time, the initial discharge efficiency can be increased even during operation.

The temperature management process of the present invention is composed of three operation modes of the remote cooling operation mode when charging, the reservation cooling operation mode when charging, and the battery temperature management mode, Figure 2 is a remote cooling and scheduled cooling mode that is a remote automatic control mode The left side shows the remote cooling mode and the right side shows the reserved cooling mode.

In addition, Figure 3 shows a battery temperature management mode, the battery temperature management mode is a process of controlling the battery temperature to the indoor cold by operating the cooling system irrespective of the battery SOC.

The battery temperature management is performed in the same process as in FIG. 3 even when the remote cooling and the reservation cooling shown in FIG. 2 are performed. In FIG. 3, the battery temperature is increased to increase the battery charging efficiency separately from the room cooling during the remote cooling and the reservation cooling of FIG. 2. It can be understood that the battery temperature management process (control of the driving of the cooling blower and the rear discharge fan, control of the battery charge amount, etc.) for managing the temperature within an appropriate temperature range is described in more detail.

In addition, the battery temperature management mode of Figure 3 is a mode that is automatically forced to maintain the battery temperature in the proper temperature range, even if there is no remote cooling request and scheduled cooling settings during the charging, when the battery temperature is out of the appropriate temperature range during charging The battery temperature management mode is forced to maintain the battery temperature at an appropriate temperature range at all times during charging, thereby increasing charging efficiency.

First, as shown in FIG. 2, when a user requests a remote cooling operation to the vehicle's wireless communication terminal by operating his terminal while charging the battery, that is, the wireless communication terminal of the vehicle is disconnected from the user terminal by the system configuration of FIG. 1. When the remote cooling operation request is received and the received remote cooling operation request is input to the charging controller through the communication controller, the charging controller checks the battery status information provided from the battery controller, that is, the battery SOC.

At this time, the charging controller turns on the air conditioning controller when the battery SOC satisfies a predetermined condition, and the air conditioning controller controls the operation of the cooling system for remote cooling through the process of calculating the indoor heat load and determining the target set temperature. do.

The charging controller also allows the battery controller to control the operation of the battery cooling system (cooling blower and rear exhaust fan) so that the battery temperature can be maintained in an appropriate temperature range.

In the SOC check process, the operation of the cooling system (operation of the air conditioning controller and the cooling system performed under the control of the air conditioning controller) takes into account the energy consumption of the cooling system according to the battery charge amount, ambient temperature, and solar radiation information for driving. The SOC condition to be activated is determined.

In this process, the charge controller determines the reference SOC value from the preset map data based on the ambient temperature and the solar radiation information. When the current battery SOC becomes higher than the reference SOC value, the charge controller determines that the remote cooling is possible and then the air conditioner is turned on. on).

FIG. 4 is an example of map data for determining a reference SOC value. A reference SOC value corresponding to a current outside temperature and insolation is extracted from the map data as illustrated, and then a reference for determining whether to perform reservation cooling during charging. Will be used.

When the battery SOC satisfies the reference SOC value or more as described above, the air conditioning controller calculates the indoor heat load, and the indoor heat load may be set to be calculated based on the indoor temperature, the outside air temperature, and the solar radiation information. The heat load calculation formula may be set as in Equation (1) below.

Indoor heat load = Offset + K1 × (T1-Tin) + K2 (1)

Here, Tin represents the room temperature, Offset, K1, K2 values are values that are determined in advance from the previous test for the vehicle, K1 is the compensation coefficient related to the indoor temperature, K2 is the compensation coefficient related to the outside temperature and solar radiation to be.

The indoor heat load value calculated as described above is used to determine the target set temperature, wherein the target set temperature is determined from data defining a correlation between the indoor heat load and the target set temperature.

FIG. 5 shows an example of data used to determine a target set temperature from an indoor heat load value. When the indoor heat load is less than a preset L, the target set temperature is determined to be T1, and when it is greater than or equal to L, T2 is determined.

When the indoor heat load and the target setting temperature are determined as described above, the operation of the cooling system is started, the operation time is counted from the time when the operation of the cooling system is started, and then the indoor temperature is set by the operation and control of the cooling system. Indoor cooling is achieved to reach.

The cooling system should be operated within the limits of the power supplied from the outside of the vehicle and the battery charge should also be taken into account.

To achieve this, it is necessary to reach the target set temperature with the minimum energy, and also to manage the energy consumed by the operation of the cooling system after reaching the target.

Therefore, under the control of the air conditioning controller during operation of the air conditioning system, it is preferable that the on / off of the compressor, the air flow rate and the wind direction are set to be controlled according to the indoor heat load of the vehicle in real time, and basically the bet cycle mode to minimize the ventilation loss. The cooling system is operated by setting the internal and external gear position to the bet circulation mode.

6 is a view showing an example of the on / off control of the compressor, the air volume and the wind direction control according to the indoor heat load calculated in the previous step, and as shown, controls the on / off of the compressor according to the indoor heat load, The amount of air is controlled by controlling the driving voltage (driving speed) applied to the air conditioning blower according to the heat load.

Referring to (b) of FIG. 6, an example of map data in which a driving voltage is defined according to indoor heat load is illustrated, and a control value for indoor heat load is extracted from the map data to control driving and air volume of the air conditioning blower.

In addition, the direction of the cooling air discharged to the vehicle interior is controlled by controlling the position of the mode control door according to the indoor heat load (control of the wind direction mode), as shown in FIG. The cooling air is controlled to be discharged through the vent (Mode 1), and when the indoor heat load is low, the cooling air is controlled to be discharged through the vent of the face and the foot (Mode 2).

Also, the air conditioner may be set to control the compressor operation after determining the compressor operation allowable power and the operation target amount (corresponding to the evaporator target temperature) based on the room temperature and the target set temperature.

That is, FIG. 7 is a diagram showing an example of a compressor allowable power (a) and an evaporator target temperature (b) setting map, wherein the compressor operation allowable power and the operation target amount-related evaporator target temperature depend on the difference between the target set temperature and the indoor temperature fed back. Based on the extracted configuration map as shown in (a) and (b) of FIG. 7, the extracted value is reflected in the operation of the compressor.

For example, the operating power of the compressor is limited to within the compressor operating allowable power determined as described above, and the compressor operating allowable power is adjusted upward as the difference between the target set temperature and the room temperature increases.

In addition, after the evaporator target temperature is determined, the operation of the compressor can be controlled based on the evaporator target temperature and the evaporator temperature measured in real time by the sensor.In the condition that the evaporator temperature reaches the evaporator target temperature (the operating amount of the compressor is the operating target amount). Determined to have reached) may be applied.

In addition, the operating time of the cooling system is regulated to a preset maximum operating time (for example, 1 hour). When the maximum operating time is reached, the air conditioning controller and the cooling system are completely turned off (air conditioning off), and the battery cooling system (cooling blower) And rear discharge fan) are also turned off.

In addition, when the air conditioning system is turned off, the air conditioning controller may be set to inform the user terminal that the air cooling system is turned off (using a text message) through the communication controller and the wireless communication terminal in the vehicle.

This is to determine that the driver is out of the initial operating intention to prevent excessive power consumption.

In addition, in addition to the forced management mode for managing the battery temperature during charging (not remote cooling and scheduled cooling), the remote control operation is also performed in the same management mode as shown in FIG. The same is true for the cooling operation), the battery temperature management mode is a mode for operating the battery cooling system according to the battery temperature to maintain the battery temperature in the appropriate temperature range, the battery cooling system operation map as shown in FIG.

The battery temperature management mode will be described with reference to FIGS. 3 and 8 as follows.

First, the battery controller controls the on / off of the cooling blower and the rear discharge fan of the battery cooling system according to the battery temperature (battery cell temperature) collected in real time, in particular, as shown in the operation map of FIG. When the temperature rises above 2 ((b) condition), the cooling blower and the rear discharge fan are turned on (the cooling system is turned on) to cool the battery, and when the battery temperature rises further and rises above the reference temperature 3 ((c) condition) In addition to cooling the battery, the battery charge is limited to prevent the battery from rising.

This is to prevent the battery temperature from suddenly dropping the charging efficiency at the reference temperature 3 or more, and the charging amount limiting mode of the reference temperature 3 or more is a cooling priority mode for performing battery cooling first.

On the contrary, if the battery temperature drops below the reference temperature 2 after the battery is cooled, the charge limit is stopped and only the battery is cooled. Then, when the battery temperature drops below the reference temperature 1, the cooling blower and the rear exhaust fan are turned off (the cooling system). Operation off) to stop battery cooling.

Referring to FIG. 3, a process in which a battery controller collects battery temperature to control on / off operation of a battery cooling system (a cooling blower and a rear exhaust fan) according to the battery temperature, and a process of limiting a battery charge may be selectively performed. It can be seen that it is performed.

In addition, when the cooling system is operated at the same time, the cooling air is sucked by the cooling blower and supplied to the battery, so that the battery can be cooled more quickly.

The battery temperature management mode shown in FIG. 3 may be enforced according to the battery temperature even if there is no remote cooling request of the user or no scheduled cooling request to be described later, and thus the battery temperature during charging may be maintained in an appropriate temperature range.

As described above, in the present invention, when the user requests indoor precooling while charging at a remote location, the vehicle interior can be cooled in advance. Such a remote cooling control process controls the indoor temperature to a target set temperature and maintains the indoor temperature. As a result, after the cooling is performed in accordance with the target setting temperature, the driver can start the vehicle in a more comfortable state.

In addition, since the indoor pre-cooling is performed using the power of the external charging device during charging, it is possible to reduce the battery power consumption compared to consuming battery power by starting indoor cooling at the beginning of operation, thereby increasing the range.

In addition, the charging efficiency may be improved by battery temperature management during charging, and driving of the vehicle may be started while the battery temperature is maintained in an appropriate temperature range, and thus, an improvement in initial discharge efficiency and an increase in range may be expected.

Meanwhile, in addition to the remote cooling as described above, the scheduled cooling is another remote automatic control process of the present invention. If the user reserves a driving point by operating his terminal at a remote place while charging the battery, the cooling and battery at the scheduled driving point are performed. It is a process to allow cooling to be performed automatically.

Since reservation cooling is a process that is performed separately from remote cooling, if there is a request for reservation cooling before the request for remote cooling described above, reservation cooling is performed. On the contrary, in the case of the above-mentioned remote cooling, reservation cooling is performed separately from reservation cooling. If there is a remote cooling request before the cooling request, the remote cooling is performed.

Referring to the reservation cooling process, as illustrated in FIG. 2, when a reserved driving time is received through a wireless communication terminal and a communication controller in a vehicle, the charging controller turns on the air conditioning controller one hour before the reserved driving time. do.

The air conditioning controller then calculates the operating time of the cooling system, and at the next operating point, checks the battery SOC, calculates the indoor heat load, sets the target temperature, operates the cooling system, and operates the battery cooling system in the same way as remote cooling. Will be performed.

In the process of calculating the operation time, the air conditioning controller calculates the operation time by using the target time temperature arrival time map according to the outside temperature and the amount of insolation. An example of the arrival time map is shown in FIG. 9.

The set time arrival time map of the target set temperature is map data in which the arrival time (required time) is set according to the outside temperature and the amount of insolation. Will be obtained.

In addition, the battery SOC check is performed at the operation point obtained as described above. In this case, if the current battery SOC state is equal to or higher than the reference SOC value, the following process is performed to perform indoor precooling and battery temperature management, and do not satisfy the reference SOC value condition. If not, the operating point is deferred until the reference SOC value condition is met (the battery SOC is above the reference SOC value).
