Definitions

  • the present subject matter relates, in general, to electric vehicles and, in particular, to utilization of the electric vehicles.
  • Electric vehicles use motors for propulsion, instead of the common internal combustion engine.
  • EVs include, but are not limited to, road and rail vehicles, aircrafts, spacecrafts and underwater vessels.
  • EVs store electricity in an energy storing device, such as a battery, which can be charged from time to time.
  • EVs produce no emissions, have less maintenance costs and provide ease of operation.
  • advances in technologies such as storage cell design, braking regeneration, and motor efficiency have made electric vehicles a viable alternative to vehicles powered by internal combustion engines.
  • FIG. 1 shows a network environment implemented for utilization of an electrical vehicle (EV), in accordance with an embodiment of the present subject matter.
  • EV electrical vehicle
  • Figure 2 illustrates a battery management system for an EV, according to an implementation of the present subject matter.
  • Figure 3 shows a charging management terminal for managing charging of EVs, according to an embodiment of the present subject matter.
  • Figure 4 illustrates a method for utilizing EVs, in accordance with an implementation of the present subject matter.
  • Electric vehicles are commonly powered by on-board battery packs.
  • Battery packs generally include multiple batteries to store charge, that is used to drive the EVs.
  • the battery packs lose their stored charge and have to be recharged.
  • the storage capability of on-board battery packs used in the EVs is limited owing to different limitations, such as available space and allowable weight. Such constrains are often dictated by design of the EVs. For example, in case of e-rickshaws, space for the battery may be constrained to allow more space for passengers. Consequently, EVs have a limited range of travel and have to be recharged frequently, for instance, on a daily basis, if not more frequently.
  • Public transport EVs such as e-busses, e-rikshaws and e-scooters travel from one location to other, to meet their engagements and provide public transport services. Since public EVs also have a limited range of travel, driving public EVs without engagements lead to wastage of EV resources. For example, driving an e- rikshaw from point A to point B without any passenger amounts to wastage of battery of the e-rikshaw. Similarly, travelling from a location to a charging station for charging of the battery packs, without any engagement, may lead to ineffective utilization of resources of the e-rikshaw. [0010] According to examples of the present subject matter, techniques of EV utilization are described. In an example of the present subject matter, the described techniques allow effective utilization of the EVs by identifying available and suitable engagements for EVs during their travel.
  • current location of the EVs is determined.
  • the location of the EV may indicate a current geographic position, providing whereabouts of the EV.
  • the current location of the EV may be identified based on various known techniques, such as through use of Global Positioning System (GPS), triangulation through mobile towers, use of assisted GPS (A-GPS), and the like.
  • GPS Global Positioning System
  • A-GPS assisted GPS
  • a destination corresponding to the EV is determined.
  • the destination of the EV may either be based on current engagements that are being undertaken by the EV or may be based on future reserved engagements of the EV.
  • the destination of the EV may also be provided by the driver of the EV. For example, based on an engagement of an e-rikshaw, the e- rikshaw may be ferrying a passenger from location‘L’ to location‘M’. In such a situation, location‘M’ may be identified as the destination of the e-rikshaw.
  • another e-rikshaw may have a reserved engagement and may have to travel to a location ‘X’, at a predefined time, to pick-up a passenger. In such situation, the destination of the e-rikshaw for the reserved engagement may be identified as the location‘X’.
  • possible engagements between the current location of the EV and the destination are determined.
  • the possible engagements may allow utilization to the EV, during its travel from its current location to the destination.
  • the possible engagements between the current location of the EV and the destination of the EV may include new fulfilment for the EV, such as fulfillment to ferry passengers, fulfillment to deliver one or more products, or fulfilment of other certain services between EVs current location and the destination of the EV.
  • a set of engagements from amongst the possible engagements between the current location of the EV and the destination of the EV are determined and provided to the driver of the EV.
  • the set of engagements may be chosen from all possible engagements based on engagement parameters.
  • the engagement parameters may indicate the state of the EV along with its past plying statistics.
  • the engagements parameters may include parameters, such as time of possible engagement, availability of the EV for the possible engagement, pre -registered engagements of the EV, amount of charge left in the EV, traffic congestion between the current location of the EV and the destination of the possible engagement, ease of reaching to the destination of the possible engagement, offers available at the possible engagement, fee applicable for the possible engagement, and driver categorization.
  • 10 different possible engagements may be identified between the current location of the EV and the destination of the EV. From amongst these 10 possible engagements, a set of 7 engagements may be identified based on engagement parameters. For example, any possible engagement where traffic condition is poor may not be included the set of engagements. Further, any engagement which has an additional offer for the driver of the EV may be included. Furthermore, if the possible engagement takes the EV closer to a charging station, such an engagement may be included in the set of the engagements.
  • a possible engagement may be included in the set of engagements based on the categorization of the driver of the EV. That is, depending on the category into which the driver of the EV has been categorized into, possible engagement may be included or removed from the set of engagements to be provided to the driver. [0017] In an example implementation, certain possible engagements may only be provided to drivers who have been categorized in top categories based on their driving behavior. For example, drivers with driving behavior better than others, may be assigned a possible engagement with maximum offers or preferable time slot.
  • the driver categorization may be indicative of driving behavior of the driver.
  • driver categorization‘A’ may indicate a driving behavior that is better than a driver categorization‘B’.
  • driver categorizations such as driver categorization ‘G, driver categorization ‘2’, . , driver categorization‘n’ may exist where each driver categorization is indicative of a ranking provided to the driver of the EV based on the driving behavior of the driver.
  • the driving behavior may be monitored over a predefined period of time.
  • the driving behavior may be usage of a battery of the EV by the driver. For instance, when a driver drives the EV at very high speed, a rate of battery drainage maybe high. The output of the battery may be monitored to determine instances of over speeding. More than a predefined number of instances of over speeding over a predefined period of time may be indicate of a poor driving behavior. In another example, erratic driving actions, such as lane changing without activating a turn indicator may also be used together with the battery usage to determine the driving behavior. Similarly, information regarding any traffic violations and accidents that the driver may have been involved in may also be accounted for determination of driver behavior. Accordingly, a variety of parameters may be monitored over a period of time and may be used to determine the driving behavior of a driver.
  • the driver is assigned to a driver categorization.
  • drivers with similar driving behavior may be assigned a same driver categorization.
  • certain other factors such as drivers credit information, driver’s history information, information regarding driving actions may be accounted for driver categorization.
  • a possible engagement is included in the set of the engagements to be provided to the driver, is based on engagement parameters, which may also include driver categorization.
  • the driver of the EV may select an engagement from the set of engagements.
  • the selection made by the driver may be based on personal preferences of the driver.
  • the destination of the EV may be updated based on the destination of the selected engagement.
  • the EV may be utilized, during periods of underutilization.

Description

IMPROVED UTILIZATION OF ELECTRIC VEHICLES
TECHNICAL FIELD
[001] The present subject matter relates, in general, to electric vehicles and, in particular, to utilization of the electric vehicles.
BACKGROUND
[002] The advancement of technology in the field of automobile industry has not only improved human lives but has also enabled efficient and safe transportation. With the increasing demand of oil and increasing air pollution, an increased focus is on renewable energy and alternative vehicles that can provide a reliable mode of transportation. Electric vehicles (EVs) use motors for propulsion, instead of the common internal combustion engine. EVs include, but are not limited to, road and rail vehicles, aircrafts, spacecrafts and underwater vessels. EVs store electricity in an energy storing device, such as a battery, which can be charged from time to time. EVs produce no emissions, have less maintenance costs and provide ease of operation. Also, advances in technologies such as storage cell design, braking regeneration, and motor efficiency have made electric vehicles a viable alternative to vehicles powered by internal combustion engines.

DETAILED DESCRIPTION
[008] Electric vehicles (EVs) are commonly powered by on-board battery packs. Battery packs generally include multiple batteries to store charge, that is used to drive the EVs. During operation of the EVs, the battery packs lose their stored charge and have to be recharged. Further, the storage capability of on-board battery packs used in the EVs is limited owing to different limitations, such as available space and allowable weight. Such constrains are often dictated by design of the EVs. For example, in case of e-rickshaws, space for the battery may be constrained to allow more space for passengers. Consequently, EVs have a limited range of travel and have to be recharged frequently, for instance, on a daily basis, if not more frequently.
[009] Public transport EVs, such as e-busses, e-rikshaws and e-scooters travel from one location to other, to meet their engagements and provide public transport services. Since public EVs also have a limited range of travel, driving public EVs without engagements lead to wastage of EV resources. For example, driving an e- rikshaw from point A to point B without any passenger amounts to wastage of battery of the e-rikshaw. Similarly, travelling from a location to a charging station for charging of the battery packs, without any engagement, may lead to ineffective utilization of resources of the e-rikshaw. [0010] According to examples of the present subject matter, techniques of EV utilization are described. In an example of the present subject matter, the described techniques allow effective utilization of the EVs by identifying available and suitable engagements for EVs during their travel.
[0011] In an example of the present subject matter, to provide effective utilization of EVs, current location of the EVs is determined. The location of the EV may indicate a current geographic position, providing whereabouts of the EV. In an example, the current location of the EV may be identified based on various known techniques, such as through use of Global Positioning System (GPS), triangulation through mobile towers, use of assisted GPS (A-GPS), and the like.
[0012] Upon determination of the current location of the EV, a destination corresponding to the EV is determined. The destination of the EV may either be based on current engagements that are being undertaken by the EV or may be based on future reserved engagements of the EV. The destination of the EV may also be provided by the driver of the EV. For example, based on an engagement of an e-rikshaw, the e- rikshaw may be ferrying a passenger from location‘L’ to location‘M’. In such a situation, location‘M’ may be identified as the destination of the e-rikshaw. Similarly, another e-rikshaw may have a reserved engagement and may have to travel to a location ‘X’, at a predefined time, to pick-up a passenger. In such situation, the destination of the e-rikshaw for the reserved engagement may be identified as the location‘X’.
[0013] In an example of the present subject matter, based on the determination of the current location of the EV and the destination of the EV, possible engagements between the current location of the EV and the destination are determined. The possible engagements may allow utilization to the EV, during its travel from its current location to the destination. In an example, the possible engagements between the current location of the EV and the destination of the EV may include new fulfilment for the EV, such as fulfillment to ferry passengers, fulfillment to deliver one or more products, or fulfilment of other certain services between EVs current location and the destination of the EV.
[0014] In an example of the present subject matter, a set of engagements from amongst the possible engagements between the current location of the EV and the destination of the EV are determined and provided to the driver of the EV. The set of engagements may be chosen from all possible engagements based on engagement parameters. The engagement parameters may indicate the state of the EV along with its past plying statistics. In an example, the engagements parameters may include parameters, such as time of possible engagement, availability of the EV for the possible engagement, pre -registered engagements of the EV, amount of charge left in the EV, traffic congestion between the current location of the EV and the destination of the possible engagement, ease of reaching to the destination of the possible engagement, offers available at the possible engagement, fee applicable for the possible engagement, and driver categorization.
[0015] For example, between the current location of the EV and the destination of the EV, 10 different possible engagements may be identified. From amongst these 10 possible engagements, a set of 7 engagements may be identified based on engagement parameters. For example, any possible engagement where traffic condition is poor may not be included the set of engagements. Further, any engagement which has an additional offer for the driver of the EV may be included. Furthermore, if the possible engagement takes the EV closer to a charging station, such an engagement may be included in the set of the engagements.
[0016] Also, in an example of the present subject matter, a possible engagement may be included in the set of engagements based on the categorization of the driver of the EV. That is, depending on the category into which the driver of the EV has been categorized into, possible engagement may be included or removed from the set of engagements to be provided to the driver. [0017] In an example implementation, certain possible engagements may only be provided to drivers who have been categorized in top categories based on their driving behavior. For example, drivers with driving behavior better than others, may be assigned a possible engagement with maximum offers or preferable time slot.
[0018] The driver categorization may be indicative of driving behavior of the driver. In an example, driver categorization‘A’ may indicate a driving behavior that is better than a driver categorization‘B’. In another example, driver categorizations, such as driver categorization ‘G, driver categorization ‘2’, . , driver categorization‘n’ may exist where each driver categorization is indicative of a ranking provided to the driver of the EV based on the driving behavior of the driver.
[0019] In an example, for determining the driver categorization for a driver of an EV, the driving behavior may be monitored over a predefined period of time. In an example, the driving behavior may be usage of a battery of the EV by the driver. For instance, when a driver drives the EV at very high speed, a rate of battery drainage maybe high. The output of the battery may be monitored to determine instances of over speeding. More than a predefined number of instances of over speeding over a predefined period of time may be indicate of a poor driving behavior. In another example, erratic driving actions, such as lane changing without activating a turn indicator may also be used together with the battery usage to determine the driving behavior. Similarly, information regarding any traffic violations and accidents that the driver may have been involved in may also be accounted for determination of driver behavior. Accordingly, a variety of parameters may be monitored over a period of time and may be used to determine the driving behavior of a driver.
[0020] Based on the determined driving behavior, the driver is assigned to a driver categorization. Thus, drivers with similar driving behavior may be assigned a same driver categorization. Further, in an example, certain other factors such as drivers credit information, driver’s history information, information regarding driving actions may be accounted for driver categorization. [0021] Thus, as described earlier, in an example of the present subject matter, a possible engagement is included in the set of the engagements to be provided to the driver, is based on engagement parameters, which may also include driver categorization.
[0022] In an example of the present subject matter, the driver of the EV may select an engagement from the set of engagements. The selection made by the driver may be based on personal preferences of the driver. Further, once the selection of an engagement from amongst the set of engagements is made by the driver, the destination of the EV may be updated based on the destination of the selected engagement.
[0023] Thus, based on the selection of a possible engagement, the EV may be utilized, during periods of underutilization.
[0024] The above and other features, aspects, and advantages of the subject matter will be better explained with regard to the following description and accompanying figures. It should be noted that the description and figures merely illustrate the principles of the present subject matter along with examples described herein and, should not be construed as a limitation to the present subject matter. It is thus understood that various arrangements may be devised that, although not explicitly described or shown herein, embody the principles of the present disclosure. Moreover, all statements herein reciting principles, aspects, and examples thereof, are intended to encompass equivalents thereof. Further, for the sake of simplicity, and without limitation, the same numbers are used throughout the drawings to reference like features and components.
[0025] Figure 1 illustrates a network environment 100 implemented for utilization of an EV, in accordance with an embodiment of the present subject matter. In an example of the present subject matter, the environment 100 includes multiple EVs, such as EVs 102-1, 102-n. The EVs 102-1, ... , 102-n may be communicatively connected to an electric vehicle management system (EVMS) 104 through a network 106. [0026] In an example, the EVs 102-1 , 102-n may be e-rickshaws, e- motorbikes or any other EVs that may have battery packs and may need to charge the battery packs from time to time by connecting to a charging station. Further, the EVs 102- 1 , ... , 102-n may also include hybrid vehicles that are powered not only by battery packs but are also powered by oil. However, such hybrid vehicles may also require engagements for utilization, from time to time, and may connect to the EVMS 104 for effective obtaining possible engagements. For the ease of reference, the EVs , ... , 102- n have been commonly referred to as EVs 102, hereinafter. Further, although two EV 102 have been depicted in the network environment 100, it would be noted that the multiple such EVs may ply on roads and may be connected to the EVMS 104 through the network 106.
[0027] In an example of the present subject matter, the EVMS 104 may be implemented as any known computing, such as a rack server, a blade server, a mainframe computer, a desktop, a personal computer, a notebook or portable computer, a workstation, and a laptop. Further, in one example, the EVMS 104 may be a distributed or centralized network system in which different computing devices may host one or more of the hardware or software components of the EVMS 102. It would be noted that the EVMS 102 may either operate remotely or lie within the vicinity of the EVs.
[0028] The network 106 may be a single network or a combination of multiple networks and may use a variety of different communication protocols. The network 106 may be a wireless or a wired network, or a combination thereof. Examples of such individual networks include, but are not limited to, Global System for Mobile Communication (GSM) network, Universal Mobile Telecommunications System (UMTS) network, Personal Communications Service (PCS) network, Time Division Multiple Access (TDMA) network, Code Division Multiple Access (CDMA) network, Next Generation Network (NON), Public Switched Telephone Network (PSTN). Depending on the technology, the network 106 includes various network entities, such as gateways, routers; however, such details have been omitted for the sake of brevity of the present description.
[0029] In an example of the present subject matter, the EVMS 104 may communicate with different users 108-1, 108-n of the network and EVs 102, in real-time, to determine the whereabouts of EVs, along with new engagements being requested by users 108-1, ... , 108-n. The users 108-1, ... , 108-n may be connected to the EVMS 104 through their respective communication devices 110-1, ... , 110-n. For the ease of reference, users 108-1, ... , 108-n have been commonly referred to as users 108, hereinafter. Similarly, the communication devices 110-1, ... , 110-n utilized by the users have been referred to as communication devices 110, hereinafter.
[0030] In an example of the present subject matter, the users 108 may include passengers willing to travel by the EVs 102 from one location to another further, the users 108 may also include customers/ sellers willing to receive/ ship products from one location to another. Further, the communication devices 110 utilized by the users 108 may include, but not limited to, personal digital assistants (PDAs), smartphones, laptops, desktops, pagers, messenger devices, tablets, and others.
[0031] The EVMS 104, based on the whereabouts of the EVs 102, such as their current location, destination and other operational parameters, along with the requests of the users 108, may determine possible engagements for the EVs 102. Further, the EVMS 104 may determine a set of engagements from the possible engagements, to be provided to the drivers of the EVS 102. As described earlier, the various engagement factors based on which the EVMS 104 may determine the set of engagements for the EVs may include, but not limited to, time of possible engagement, availability of the EV for the possible engagement, pre -registered engagements of the EV, amount of charge left in the EV, traffic congestion between the current location of the EV and the destination of the possible engagement, ease of reaching to the destination of the possible engagement, offers available at the possible engagement, fee applicable for the possible engagement, and driver categorization. [0032] The various engagement factors may be stored in a database 111, communicatively coupled to the EVMS 104. The database 111 may either be implemented within the EVMS 104 as an internal database or may be implemented as outside EVMS 104 as an external database.
[0033] In an example of the present subject matter, the EVs 102 may charge their battery packs through various charging stations (not shown), which may be connected through the network 106, and may support different payment methods, such as ChargePoint, Blink, Greenlots, eVgo, Aerovironment, Azra, SemaConnect, Circuit Electrique, ReseauVer, Sun Country Highway, BHIM, Bharat QR and Unified Payment Interface (UPI). Further, depending on the charging station, different rates of charging may apply, that may vary include session/monthly/yearly charges or flat charges. Some charging stations may also provide free energy to charge the battery packs of the EVs 102.
[0034] The EVs 102 may include, apart from other things, a battery management system (BMS) 112, one or more battery packs 114, at least one charging connector 116, and a sensor assembly 118.
[0035] In an example, the BMS 112 may monitor and control the utilization and charging of the battery packs 114. Further, the BMS 112 may also communicate with the charging connector 116 to control charging of the battery packs 114. Therefore, the BMS 112 can be understood to act as a control terminal of the battery packs 114. Among other functions, BMS 112 manages battery pack functions, such as monitoring current battery pack charge level, ensuring low consumption of the battery packs when in inactive mode, prevention from overcharging and under discharge. For the purpose of managing the battery functions, the BMS 112 measures various parameters of the battery packs 114, such as battery cell voltage, temperature, etc.
[0036] In another example of the present subject matter, the BMS 112 may also communicate with the sensor assembly 118 to receive various operational parameters of the EV 102. In an example, the BMS 112 may receive parameters, such as speed, location, destination of the EV 102. Further, the sensor assembly 118 may include multiple sensors to monitor and gather data corresponding to various parameters of the EV 102.
[0037] In an example of the present subject matter, the battery packs 114 may include lithium ion batteries. Other examples of the battery pack 114 may include, nickel metal hydride batteries, graphene batteries, cadmium batteries, sodium or zebra batteries. Dur to their utility and advantages over other types of batteries, lithium ion batteries, may be used in the EVs 102. A typical lithium ion battery cell yields 80-90% of discharge efficiency. Examples of the types of lithium ion batteries that can be incorporated in the EVs 102 can be NCA, NMC, LMO, and LifeP04.
[0038] The EVs 102 includes a charging connector 116. The charging connector 116 may be understood to be an input terminal to receive power and charge the battery packs 114. Examples of the charging connector 116 include but are not limited to mode 2, mode 3 charger or a plug type 1, or type 2. In accordance with an example embodiment of the present subject matter, the charging connector 116 may function in response to instructions given by a BMS 112.
[0039] The functioning of the BMS 112 and the EVMS 104 to communicate whereabouts of the EVs 102 to provide effective utilization to the EVs 102 is further described in reference to forthcoming figures.
[0040] Figure 2 illustrates a battery management system 112 for an EV, according to an implementation of the present subject matter. In an example of the present subject matter, the BMS 112 includes a communication engine 202, a control engine 204 and a data store 206. As described earlier the BMS may act as a control to the battery packs 114 of the EV 102 and may communicate with other elements of the EV 102, such as sensor assembly 118 (not shown) and charging connector 116 (not shown).
[0041] In an example, the communication engine 202 of the BMS 112 may facilitate communication between the BMS 112 and the sensor assembly 118 and charging connector 116. Further, the communication engine 202 may also facilitate communication between the BMS 112 and the EVMS 104. The communication may typically be based on known communication protocols. The communication engine 202 may use several methods of serial or parallel communication, for instance and not limited to, CAN bus communication, which is commonly used in automotive environments, DC-BUS for serial communication, and different types of wireless communication. The communication protocols can vary as per the hardware implementation.
[0042] The communication engine 202 communicates internally with various sensors of the sensor assembly 118 (not shown) that may be installed on the EVs 102 and transmits the inputs obtained from the sensors to the EVMS 104. The communication engine may also receive inputs from the driver of the EVs 102 relating to their preferences and may communicate them to the EVMS 104. Based on the inputs obtained from the sensor assembly 118 and other battery information communicated by the communication engine 202 to the EVMS 104, the EVMS 104 may identify the whereabouts of the EVs 102 along with driver preferences.
[0043] The control engine 204 may control the functioning of the battery packs
114 of the EV 102. For example, the control engine 204 may be responsible for controlling the trigger signals to the charging connector which may determine charging of the battery packs 114. In an example implementation, the control engine 204 controls the charging of the battery packs 114 as per predefined rule. The control engine 204 instructs the charging connector 116 (not shown) of the EVs 102 to either connect to the supply terminals of the charging station 110 (not shown) or stop the charging process. The control engine 204 also controls the charging schedule for the vehicle by ensuring the charging is done as per the charging orders received from the EVMS 104. The control engine 204 also ensures that the charging of the battery packs 114 is in accordance with instructions provided by the EVMS 104, if any. For example, if the EVMS 104 determines a rate of charging for the battery packs 114, the control engine 204 ensures that the battery packs 114 charge at the specified rate by controlling the charging connecter 116 accordingly.
[0044] In the present description, the engine(s) may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement certain functionalities of the engine(s), such as transmitting signals. In examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, engine(s) may be implemented by electronic circuitry.
[0045] In an example implementation, the data store 206 may be understood as a memory component to store various data collated, manipulated or otherwise used by the BMS 112 in its operation. The memory component may include any computer- readable medium including, for example, volatile memory (e.g., RAM), and/or non volatile memory (e.g., EEPROM, flash memory, etc.).
[0046] The data store 206 may store information, for example and not limited to, inputs obtained from the sensor assembly 118 installed on the EVs 102, such as EV geographic location, destination of the EV, speed of the EV, direction of travel of the EV and current charge level information of the EV. The data store 206 may also store instructions communicated to the BMS 112 by the EVMS 104, such as set of engagements. Other examples of information that the data store 206 may store are: customer rating in case of an electric rickshaw, battery maintenance data, drivers credit information, driver’s history information, information regarding driving actions.
[0047] Figure 3 schematically depicts various components of an electric vehicle management system 104, according to an example of the present subject matter.
[0048] The EVMS 104, among other things, includes processor(s) 302 and memory 304 and interface(s) 306 coupled to the processor(s) 302. The processor(s) 302 may be implemented as microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, and/or any devices that manipulate signals based on operational instructions. Among other capabilities, the processor(s) 302 is configured to fetch and execute computer- readable instructions stored in a memory 304 of the EVMS 104. The memory 304 may include any computer-readable medium including, for example, volatile memory (e.g., RAM), and/or non-volatile memory (e.g., EEPROM, flash memory, etc.).
[0049] The functions of the various elements shown in the Figures, including any functional blocks labelled as“processor(s)”, may be provided through the use of dedicated hardware as well as hardware capable of executing software. When provided by a processor, the functions may be provided by a single dedicated processor, by a single shared processor, or by a plurality of individual processors, some of which may be shared. Moreover, explicit use of the term“processor” should not be construed to refer exclusively to hardware capable of executing software, and may implicitly include, without limitation, digital signal processor (DSP) hardware, network processor, application specific integrated circuit (ASIC), field programmable gate array (FPGA), read only memory (ROM) for storing software, random access memory (RAM), non-volatile storage. Other hardware, conventional and/or custom, may also be included.
[0050] The interface(s) 306 may include a variety of software and hardware interfaces that allow the EVMS 104 to interact with BMS 112 of one or more EVs 102 and the communication devices 110 of the users 108. In an example of the present subject matter, the EVMS 104 may further include engines 308 and data 310. The engines 308 may either be implemented within the EVMS 104 in the memory 304, or may reside in an external database, such as database 111 (not shown). The engines 308 include routines, programs, objects, components, data structures, and the like, which perform particular tasks or implement particular abstract data types.
[0051] In an example of the present subject matter, the engines 308 may include an analysis engine 312, a communication engine 314, and other engines 316. The communication engine 314 may allow the EVMS 104 to communicate with the EVs 102 and its components, such as BMS 112, and communicating devices 110. Further, the analysis engine 312 may analyze different factors and data provided by the BMS 112 along with available engagements for the EVs 102.
[0052] In operation, the communication engine 314 of the EVMS 104 may communicate with the BMS 112 of the EVs 102 to receive different data, such as current engagement of the EVs 102, current location of the EVs 102, destination of the EVs based on their current engagements, battery usage patterns of EVs, and driver behavior of the EVs 102. In an example, the communication engine 314 may receive whereabouts of the EVs 102 through the communication engine 202 of the BMS 112. Further, the communication engine 314 of the EVMS 104 may also communicate with the database 111 (not shown) to obtain information related to the EVs 102, that may have been provided by the EVs 102 to the EVMS 104 over time.
[0053] In an example of the present subject matter, the communication engine
314 of the EVMS 104 may also communicate with different users 108 to obtain all engagements either being undertaken by the users 108 or being requested by the users 108. As described earlier, the users 108 may utilize their communication devices 110 to communicate their engagements with the EVMS 104. In an example, the EVMS 104 may act as a nodal platform to gather engagement requests from the users 108 and provide such requested engagements to the EVs 102 based on engagement parameters. The engagement parameters may indicate the state of the EV 102 along with EVs past plying statistics.
[0054] In an example implementation of the present subject matter, the analysis engine 312 may analyze different parameters received from each EV, such as current location of the EV, destination of the current engagement of the EV, along with all available engagements received from different users to determine possible engagements for the EV. The possible engagements identified for each EV may further be refined to generate a set of engagements for the EV.
[0055] The analysis engine 312 may identify the set of engagements for the EV based on engagement parameters, such as time of possible engagement of the EV, availability of the EV for the possible engagement, pre-registered engagements of the EV, amount of charge left in the EV, traffic congestion between the current location of the EV and the destination of the possible engagement, ease of reaching to the destination of the possible engagement, offers available at the possible engagement, fee applicable for the possible engagement, and driver categorization.
[0056] In an example implementation, the analysis engine 312 may determine the driver categorization for a driver of an EV based on the driving behavior, monitored over a predefined period of time. In an example, the driving behavior may be usage of a battery of the EV by the driver. For instance, when a driver drives the EV at very high speed, a rate of battery drainage maybe high. The output of the battery may be monitored to determine instances of over speeding. More than a predefined number of instances of over speeding over a predefined period of time may be indicate of a poor driving behavior. In another example, erratic driving actions, such as lane changing without activating a turn indicator may also be used together with the battery usage to determine the driving behavior. Similarly, information regarding any traffic violations and accidents that the driver may have been involved in may also be accounted for determination of driver behavior. Accordingly, a variety of parameters may be monitored over a period of time and may be used to determine the driving behavior of a driver.
[0057] Based on the determined driving behavior, the analysis engine 312 may assign a driver, a driver categorization. Thus, drivers with similar driving behavior may be assigned a same driver categorization. Further, in an example, certain other factors such as drivers credit information, driver’s history information, information regarding driving actions may be accounted for by the analysis engine 312 driver categorization.
[0058] Thus, as described earlier, in an example of the present subject matter, a possible engagement is included in the set of the engagements to be provided to the driver, is based on engagement parameters, which may also include driver categorization. [0059] The analysis engine 312 may utilize one or more of the engagement parameters to determine the set of engagements for the EV. It would be noted that the analysis engine 312 may utilize different weightage for the different engagement parameters, that may be defined by the EVMS 104.
[0060] In an example of the present subject matter, the communication engine
314 of the EVMS 104 may provide the set of engagements to the driver of the EV. The driver of the EV may choose an engagement from the set of engagements to increase the utilization of the EV. In an example, the engines 308 may also include other engines 316 that supplement functions of the EVMS 104. The data 310 serves, amongst other things, as a repository for storing data that may be fetched, processed, received, or generated by the engines 308. The data 310 comprises data provided by the BMS 112, such as battery charge data 318, EV location data 320, EV destination data 322, driver categorization data 324, and other data 326 corresponding to the other engines 316.
[0061] In an example implementation of the present subject matter, the communication engine 314 may further receive a selection from the driver of the EV 102, where the selection is indicative of an engagement from amongst the set of engagements, chosen by the driver of the EV 102. Further, the analysis engine 312 may further provide an updated route to the driver of the EV 102 based on the selection.
[0062] In an example, the analysis engine 312 of the EVMS 104 may provide the updated route that may include a new destination for the EV (102). The new destination may be either a pickup location of a user or a charging station allocated to the EV (102).
[0063] It would be noted that the charging station allocated to the EV 102 may control a charging schedule of the EV (102) by enabling the charging to be done only at the time slot allotted to the EV (102).
[0064] Figure 4 illustrate a method 400 for utilization of EVs, in accordance with an implementation of the present subject matter. Although the method 400 may be implemented in a variety of EVs, for the ease of explanation, the present description of the example method 400 of utilization of the EVs is provided in reference to e- rickshaws. Also, although the method 400 may be implemented in a variety of computing devices, but for the ease of explanation, the present description of the example method 400 for utilization of EVs is provided in reference to the above - described BMS 112 and EVMS 104.
[0065] The order in which the method 400 is described is not intended to be construed as a limitation, and any number of the described method blocks may be combined in any order to implement the method 400, or any alternative methods. Furthermore, the method 400 may be implemented by processor(s) or computing device(s) through any suitable hardware, non-transitory machine-readable instructions, or combination thereof.
[0066] It may be understood that blocks of the method 400 may be performed by programmed computing devices. The blocks of the method 400 may be executed based on instructions stored in a non-transitory computer-readable medium, as will be readily understood. The non-transitory computer-readable medium may include, for example, digital memories, magnetic storage media, such as magnetic disks and magnetic tapes, hard drives, or optically readable digital data storage media.
[0067] Referring to Figure 4, at block 402 current location of an electric vehicle
(EV) is determined. In an example of the present subject matter, the current location of the EV is determined based on known techniques, such as through use of Global Positioning System (GPS), triangulation through mobile towers, assisted GPS (A- GPS), and the like. Further, the current location of the EV may be provided to an EV management system, such as the EVMS.
[0068] At block 404, destination of the EV is identified. The destination of the EV may either be determined based on current engagement information of the EV or may be provided by the driver of the EV. In an example, the EVMS 104 may identify the destination of the EV based on its current engagement. [0069] At block 406, possible engagements for EV between the current location and the destination of the EV are checked. In an example of the present subject matter, the EVMS 104 receives different engagement requests from different users and based on the current location of the EV, the destination of the EV and other EV parameters, the EVMS 104 may determine possible engagements for the EV. The possible engagements between the current location of the EV and the destination of the EV may include engagements to ferry passengers, deliver one or more products, or provide certain services between EVs current location and the destination of the EV.
[0070] At block 408, driver of the EV is provided with a set of engagements between the current location and the destination of the EV. The set of engagements are determined by the EVMS 104 based on different engagement parameters, such as time of possible engagement of the EV, availability of the EV for the possible engagement, pre-registered engagements of the EV, amount of charge left in the EV, traffic congestion between the current location of the EV and the destination of the possible engagement, ease of reaching to the destination of the possible engagement, offers available at the possible engagement, fee applicable for the possible engagement, and driver categorization.
[0071] At block 410, a selection of an engagement from amongst the set of engagements is received from the driver of the EV. Further, at block 412, the destination of the EV is updated based on the selected engagement.
Although the subject matter has been described in considerable detail with reference to certain examples and implementations thereof, other implementations are possible. As such, the present disclosure should not be considered limited to the description of the preferred examples and implementations contained therein.
