In particular, the present disclosure relates to a system to generate alert to driver of the electric vehicle when discharge rate of high voltage traction battery (main battery) is above a threshold level and a method for implementing the same.
BACKGROUND
[0002] Background description includes information that may be useful in understanding the present subject matter. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed subject matter, or that any publication specifically or implicitly referenced is prior art.
[0003] In electric vehicles, a traction battery pack is provided which is primary energy source for providing energy for traction of vehicle. The traction battery pack has a battery string having a plurality of battery modules connected in series or parallel with each other. Further, driving motor and auxiliary loads, such as, heating ventilation and air conditioning (HVAC), head lamps, music system, wiper, water pump, etc., are connected with the traction battery pack to take energy for operations.
[0004] Generally, a battery management system (BMS) is connected with the traction battery pack to measure health and state of charge (SOC). When the SOC is below a threshold level, for example, 10%, the BMS issues an alert to the user/driver that the traction battery pack is about to be discharged and therefore recharge is required.
[0005] Further, whenever there is any fault, such as degraded health of battery modules in the traction battery pack or fault in connection between the traction battery pack and auxiliary loads, the BMS generates a corresponding alert to the

user. Based on the alert, the user may take necessary corrective action to resolve the fault.
[0006] When the high voltage battery consumption or traction battery consumption rate is very high due to simultaneous activation of various auxiliary loads and/or rash driving (i.e., continuous high acceleration), it results in faster discharge of the traction battery pack.
[0007] Presently, the existing systems calculate the high discharge rate of traction battery pack and allows or stops traction of electric vehicle on the traction battery pack. Other existing systems provide information about the drivable range, for example, with existing traction battery the vehicle can drive upto 50Km. Further, these drivable ranges are not fixed and change after fix span of time when vehicle re-calculates the drivable range and displays the same to the driver.
[0008] For example, when discharge rate of the traction battery is high and SOC of the traction battery pack is 70%, the existing alert system notifies the driver that the vehicle can drive up to 150Km with current battery SOC. However, after some time, when the alert system recalculates the drivable range based on remaining SOC of the traction battery pack which is now 10%, the alert system notifies that the vehicle can drive up to 15Km.
[0009] None of the existing system detects the discharge rate and provides and early warning based on calculated discharge rate of the traction battery pack and provide more drivable range.
[0010] Accordingly, there is a need for methods and systems for providing a mechanism that can determine corrective measures to reduce the high discharge rate and notifies or alerts the same to the driver.
OBJECTS OF THE DISCLOSURE
[0011] Some of the objects of the present disclosure, which at least one embodiment herein satisfy, are listed hereinbelow.

[0012] A general object of the present disclosure is to provide methods and systems for providing a mechanism that can determine corrective measures to reduce the high discharge rate and notifies or alerts the same to the driver.
[0013] An object of the present disclosure is to provide an Electric vehicle alert system that can receive drivers input on the notified corrective measures and implement the corrective measures.
[0014] Another object of the present disclosure is to provide an Electric vehicle alert system that can store the driver's preference/selection/action on the notified corrective measures for future determination and prioritization of the corrective measures based on the driver's previous behaviour.
[0015] These and other objects and advantages of the present invention will be apparent to those skilled in the art after a consideration of the following detailed description taken in conjunction with the accompanying drawings in which a preferred form of the present invention is illustrated.

[0038] Embodiments and/or implementations described herein relate to methods and systems for generating alerts to user/driver of an electric vehicle when battery discharge rate (DR) is more than a predefined threshold value (TH) and reducing the battery discharge rate (DR) based on the inputs received from the user on the generated alerts.
[0039] In an aspect, the Electric vehicle has various auxiliary loads, such as HVAC, infotainment system, wiper, head lamps, fog lamps, etc.
[0040] Referring to figure 1, the electric vehicle alert system 100 can be implemented in battery management system (BMS) or vehicle control unit (VCU). In another embodiment, the electric vehicle alert system 100 can be a standalone system that is in communication with the BMS and the VCU and other auxiliary loads of the vehicle via CAN bus. The electric vehicle alert system 100 (hereinafter can be referred as EV alert system 100 or system 100 interchangeably) includes a processor(s) 102, an interface(s) 104, a memory 106.
[0041] The processor(s) 102 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, logic circuitries, and/or any devices that manipulate data based on operational instructions.
[0042] Among other capabilities, the one or more processor(s) 102 are configured to fetch and execute computer-readable instructions and one or more routines stored in the memory 106. The memory 106 may store one or more computer-readable instructions or routines, which may be fetched and executed to perform action of the processing unit 108 in an electric vehicle alert system 100 for alerting the user. The memory 106 may include any non-transitory storage device including, for example, volatile memory, such as RAM, or non-volatile memory, such as EPROM, flash memory, and the like.
[0043] The interface(s) 104 may include a variety of interfaces, for example, interfaces for data input and output devices referred to as I/O devices, storage devices, and the like. The interface(s) 104 may facilitate communication of the

system 100 with various devices coupled to the system 100. The interface(s) 104 may also provide a communication pathway for one or more components of the system 100. The interface(s) 104 provides communication pathway for traction battery pack 200, driver motor 300, auxiliary loads 400 and a display device 500 to the system 100. Further, the system 100 is in communication with the one or more components via CAN network or direct cable connection. Examples of such components include, but are not limited to, processing unit(s) 108 and data 110.
[0044] The processing unit(s) 108 may be implemented as a combination of hardware and programming (for example, microcontroller or programmable instructions) to implement one or more functionalities of the processing unit(s) 108. In examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processing unit(s) 108 may be processor-executable instructions stored on a non-transitory machine-readable storage medium and the hardware for the processing unit(s) 108 may include a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the machine-readable storage medium may store instructions that, when executed by the processing resource, implement the processing unit(s) 108. In such examples, the system 100 may include the machine-readable storage medium storing the instructions and the processing resource to execute the instructions or the machine-readable storage medium may be separate but accessible to the system 100 and the processing resource. In other examples, the electric vehicle alert system 100 can be implemented as a microcontroller with preloaded instructions for execution. The processing unit(s) 108 may be implemented by electronic circuitry.
[0045] In an aspect, the processing unit(s) 108 may include a monitoring unit 112, an alert generation unit 114, a feedback update unit 116 and a display unit 118. The processing unit(s) 108 may include other unit(s) which may implement functionalities that supplement applications or functions performed by the system 100 or the processing unit(s) 108.

[0046] Further, the data 110 may include data that is either stored or generated as a result of functionalities implemented by any of the components of the processing unit(s) 108. In some aspects, the data 110 may be stored in the memory 106 in the form of various data structures. Additionally, data 110 can be organized using data models, such as relational or hierarchical data models. The data 110 may store data, including temporary data and temporary files, generated by the processing unit(s) 108 for performing the various functions of the system 100.
[0047] In operation, the system 100 is in communication with various sensors, traction battery pack 200, drive motor 300, and a plurality of auxiliary loads 400 through the interfaces 104. The system 100 receives inputs from the plurality of auxiliary loads 400 through CAN network. The system 100 is also in communication with the Battery Management System (BMS) of the traction battery pack 200 and vehicle control unit (VCU) or Engine Control Unit (ECU).
[0048] The monitoring unit 112 coupled with the drive motor 300 and the plurality of auxiliary loads 400. The monitoring unit 112 determines battery discharge rate (DR) of the traction battery pack 200 by drive motor 300 and the plurality of auxiliary loads 400. The battery discharge rate (DR) means battery consumption by the drive motor 300 and the plurality of auxiliary loads 400 over the time and over the distance covered by the electric vehicle. The auxiliary load such as HVAC may consume battery even when vehicle is not in traction mode. Therefore, the battery discharge rate (DR) depends on both the time when electric vehicle is in ON condition and when vehicle is in traction mode. The monitoring unit 112 also determines battery consumption rate (CR) of the drive motor 300 and battery consumption rate (CR) of each of the plurality of auxiliary loads (300).
[0049] The monitoring unit 112 compares the battery discharge rate (DR) with a predefined threshold limit (THV) pre-stored in the memory 106. The monitoring unit 112 also compares the battery consumption rate (CR) of each of the auxiliary load from the plurality of auxiliary loads 400 with predefined corresponding threshold values (Tl, T2... .Tn) of each auxiliary load. The alert generation unit 114

generates an alert notification when the battery discharge rate (DR) is more than the predefined threshold limit (THV) of the traction battery pack 200 and the battery consumption rate (CR) of at least one of auxiliary load from the plurality of auxiliary loads 400 is more than predefined corresponding threshold value (Tl, T2... .Tn).
[0050] The display unit 118 selects the auxiliary loads from the plurality of auxiliary loads 300 that have battery consumption rate (CR) more than the predefined corresponding threshold value (Tl, T2...Tn) and prepare a list of the selected auxiliary loads. The display unit 118 displays the list of auxiliary loads 400 on a display device 500 through the CAN network to user/driver of the vehicle. For example, the HVAC, the infotainment system, wiper, and head lamps have more battery consumption rate (CR) than the predefined corresponding threshold value. The display unit 118 selects the HVAC, the infotainment system, wiper and head lamps, and displays the list of selected loads to the user on the display device 500 of the vehicle.
[0051] The feedback update unit 116 of the system 100 is coupled with the plurality of auxiliary loads 400 and the display device 500. Upon displaying the selected list of auxiliary loads 400 to the user of the driver, the feedback update unit 116 is configured to receive inputs from the user on the displayed list of auxiliary loads 400. For example, the user selects HVAC to be OFF and dismiss the pending auxiliary loads, such as infotainment system and head lamps. The feedback update unit 116 receives the user inputs and control the plurality of auxiliary loads 400 based on the received inputs. For example, the feedback update unit 116 switches OFF the HVAC unit and keeps the other auxiliary loads, such as infotainment system and headlamps in ON condition. The feedback update unit 116 also updates the data 110 about the feedback or inputs from the user about the auxiliary loads. Based on the received inputs from the user, the feedback update unit 116 determines that HVAC unit is not a preference for the user as compared to infotainment system and head lamps. Therefore, the feedback update unit 116 keeps the HVAC unit in OFF condition and other auxiliary loads in ON condition.

[0052] With the implementation of user preference on the auxiliary loads, the battery discharge rate (DR) is reduced to increase the driveable range of the electric vehicle.
[0053] With the current feedback or inputs by the user, the feedback update unit 116 updates the user preference in the data 110 so that when the system 100 re-calculates/re-determines the battery consumption rate (CR) of the auxiliary loads in the next cycle before turn OFF condition of the electric vehicle, the monitoring unit 112 determines battery consumption rate (CR) of the auxiliary loads apart from the previous selected auxiliary loads.
[0054] Based on the current feedback or inputs by the user, the feedback update
unit 116 updates the threshold values (Tl, T2 Tn) of each of the auxiliary load
from the list of selected auxiliary loads. The feedback update unit 116 reduces the threshold value of the HVAC unit as this is not preferred by the user as compared to other auxiliary loads 300. Therefore, the feedback update unit 116 keeps updating the threshold values (Tl, T2... .Tn) of the plurality auxiliary loads 400 based on the user inputs.
[0055] With the reduced threshold value of the HVAC unit, the system 100 compares the battery consumption rate (CR) of the HVAC unit with the reduced threshold value and displays the same on high priority to the user for action.
[0056] For example, at the first cycle of determination, the threshold value of the HVAC unit is 2 mAh. Based on the user inputs, the feedback update unit 116 reduces the threshold value of the HVAC unit by 10% and distributes 10% of threshold value by increasing threshold value of the auxiliary loads, such as infotainment system and head lamps selected by the user for ON condition. The feedback update unit 116 stores the updated threshold values of the auxiliary loads 400 in the data 110 for future determination cycles. In the next cycle of the determination and alert generation after every event of starting the electric vehicle, the system 100 considers the updated threshold values from the data 110 for generating and displaying the alert notification.

[0057] Referring to fig. 3, the feedback update unit 116 reduces and increases the threshold values of each of the auxiliary units by a predefined value.
T0 = x{de fault) Equation 1
Where equation 1 indicates default threshold value T0 of the auxiliary load which can be increased or decreased based on the user preference by a pre-stored value.
For example, at first time, when the user prefers to OFF the auxiliary load, such as HVAC the feedback update unit 116 decreases the default threshold value by the pre-stored value Ai and stored the decreased value in the data 110.
T_! = T0 - Ai
[0058] At second time, the system 100 considers the updated threshold values T-i from the data 110 for generating and displaying the alert notification. If again the user selects the same auxiliary load, such as HVAC to be OFF. The Feedback update unit 116 further decreases the last updated value T-i by pre-stored value A2.
T.2= T-i- A2
Similarly further decrease in the threshold value by the pre-stored value A3.
T.3 = T-2-A3
Further, there is limit which is pre-stored in the memory by which threshold value can be decreased.
[0059] Similarly, the threshold values of the auxiliary loads which are retained by the user are increased by pre-stored values, such as Ai, A2, A3. There is limited which is pre-stored in the memory up to which value can be increased.
T+i= T0+ Ai
T+2 = T+i + A2
T+3 = T+2 + A3
[0060] Further, value of pre-stored values in the memory can be same or different with each other.

[0061] The feedback update unit 116 keeps updating threshold values of the auxiliary loads 400 based on the user preference and the monitoring unit 112 uses the updated threshold values for determining the battery consumption rate (CR) and selecting the auxiliary loads 400 that have more battery consumption rate (CR) than the updated threshold values.
[0062] In this way, the present disclosure not only provides a solution for alerting the user about high battery discharge rate (DR) but also provides a solution for reducing the high battery discharge rate (DR) based on the user/driver preference and increases the driveable range of the electric vehicle. Apart from these feature, the system 100 also stores the user preference over the auxiliary loads 400 and update the database of predefined threshold values to provide alert as per preference of the user based on previous selections. With the present implementation of the system 100 in the electric vehicle, the system 100 learns from the user behaviour and selects the auxiliary loads to reduce the high battery discharge rate (DR).
[0063] FIG. 2 illustrates a method 600 for implementing an electric vehicle alert system 100, according to an embodiment of the present disclosure. The order in which the method 600 is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any appropriate order to carry out the method 600 or an alternative method. Additionally, individual blocks may be deleted from the method 600 without departing from the scope of the subject matter described herein.
[0064] At block 601, the method 600 includes determining battery discharge rate (DR) of a traction battery pack 200. In an aspect, the monitoring unit 112 determines the battery discharge rate (DR) by determining battery consumption rate (CR) of the drive motor 300 and of the plurality of auxiliary loads 400. With the combination of battery consumption rate (CR), the monitoring unit 112 determines the total battery discharge rate (DR). In an aspect, the monitoring unit 112 is coupled with the BMS of the traction battery pack 200 to determine the battery discharge rate (DR).

[0065] At block 602, the method 600 includes comparing the battery discharge rate (DR) with the predefined threshold value (THV) of the traction battery pack 200 pre-stored in the memory 106. When the battery discharge rate (DR) is more than predefined threshold value (THV), the method 600 proceeds to block 603. When the battery discharge rate (DR) is less than predefined threshold value (THV), the method 600 re-determines the battery discharge rate (DR) at block 601.
[0066] At block 603, the method 600 includes comparing, by the monitoring unit 112, the determined battery consumption rate (CR) with the corresponding threshold values (Tl, T2....tn) of the plurality of auxiliary loads 400. The corresponding threshold values (Tl, T2,.. .Tn) are pre-stored in the memory 106 or the data 110.
[0067] At block 604, the method 600 includes generating, by alert generation unit 114, alert notification when the battery discharge rate (DR) is more than a predefined threshold limit (THV) of the traction battery pack 200 and the battery consumption rate (CR) of at least one of auxiliary load from the plurality of auxiliary loads 400 is more than predefined corresponding threshold value (Tl, T2... .Tn).
[0068] At block 605, the method 600 includes selecting, by the display unit 118, a list of auxiliary loads from the plurality of auxiliary loads 400 that have battery consumption rate (CR) more than the predefined corresponding threshold value (Tl, T2...Tn).
[0069] At block 606, the method 600 includes displaying, by the display unit 118, the list of selected auxiliary loads to the user by the generated alert notification on a display device 500, such as infotainment system or instrument panel display device. The generated alert notification contains the list of selected auxiliary loads and pop up the same on the display device.
[0070] At block 607, the method includes receiving, by the feedback update unit 116, inputs from the user on the displayed list of auxiliary loads 400. The user inputs include OFF and dismiss of auxiliary loads information. The user input OFF

means switch OFF the auxiliary load selected by the user and dismiss means user needs these auxiliary loads without further alert notifications.
[0071] At block 608, the method 600 includes controlling, by the feedback update unit 116, the plurality of auxiliary loads 400 based on the user inputs. In an aspect, if user wants to switch OFF the auxiliary load, the feedback update unit 116 switches OFF the particular auxiliary load.
[0072] At block 609, the method 600 includes updating, by the feedback update unit 116, the threshold values of the plurality of auxiliary loads based on the user inputs.
[0073] Thus, with the implementation of the present system and method, the
present system and method not only provide a solution for generation of alert when the battery discharge rate (DR) is high but also provides a solution for reducing the battery discharge rate (DR) based on the user preference. Further, the present system and the method update the database based on the user preference to generate the alert notification.
