SYSTEM AND METHOD FOR BATTERY EXCHANGE USING AUTONOMOUS
MOBILE ROBOTS
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the priority of the Provisional Patent Application with serial number 201841028628, filed in the Indian Patent Office on July 30, 2018, with the title “A SYSTEM AND A METHOD FOR PERFORMING BATTERY EXCHANGE USING AUTONOMOUS MOBILE ROBOT”, and subsequently post-dated by 3 months to October 30, 2018. The content of the Provisional Patent Application is incorporated in its entirety by reference herein.
BACKGROUND
Technical Field
[0002] The embodiments herein are generally related to electric vehicles. The embodiments herein are particularly related to a system and a method for battery exchange in electric vehicles. The embodiments herein are more particularly related to a system and a method for exchanging spent batteries with charged batteries in multiple electric vehicles simultaneously using multiple autonomous mobile robots that communicate with multiple components in a battery exchange station.
Description of the Related Art
[0003] Electric vehicles typically require either charging or replacement/exchange of batteries at regular intervals. A battery exchange process involves physical swapping of the fully or partially discharged or spent battery with a fully charged battery. Conventional systems developed for the process of battery swapping rely on a fixed infrastructure to guide and position the electric vehicles for battery exchange. These systems are typically installed at battery exchange stations and use conveyor belts and/or lifts and additional fixed infrastructure to position an electric vehicle accurately. In the battery exchange process using the fixed infrastructure, spent batteries are removed from the electric vehicle and moved out using a conveyor system and fully charged batteries are brought in using the conveyor system and fitted into the electric vehicle. However, costs involved in building the fixed infrastructure required for the battery exchange process are typically very high. Moreover, the fixed infrastructure is typically designed to serve one electric vehicle at a time. Servicing of several electric vehicles at a time requires duplication of the fixed infrastructure and hence, substantially increases the costs. Furthermore, in case of any malfunction in the fixed infrastructure, the battery exchange station becomes fully or partially unavailable and non- operational until serviced. Moreover, temporary installation of the fixed infrastructure in the battery exchange station is not possible, until a permanent infrastructure is serviced, due to the space required for the fixed infrastructure and the difficulty of moving the fixed infrastructure from one place to another. Moreover, in these fixed infrastructures, the location where a battery is exchanged is closely coupled with the location where batteries are charged and stored using conveyors or rollers.
[0004] Furthermore, some conventional systems for battery exchange require a driver of an electric vehicle to park the electric vehicle accurately. Accuracy of parking is typically in the range of few centimetres or less when an automated battery exchange is intended. However, achieving such precision in parking of the electric vehicle is difficult for drivers and takes a long time. Even with positioning systems installed in the electric vehicles, the weight of the electric vehicles makes it difficult for drivers to position the electric vehicles accurately for battery exchange in conventional systems.
[0005] Moreover, it is difficult to meet the demand for performing multiple battery exchanges simultaneously in conventional battery exchange stations without having to install multiple fixed infrastructures permanently. These battery exchange stations also do not account for malfunctions of equipment used for performing the battery exchanges and hence are rendered non-operational during high demand, resulting in significant losses in revenues of the battery exchange stations. Furthermore, the conventional battery exchange stations are not equipped for dynamic and intelligent positioning, movement, and operations of functional components therewithin for ensuring optimal and simultaneous battery exchange processes within the battery exchange stations.
[0006] Hence, there is a long-felt need for a system and a method for performing battery exchanges in manually and autonomously driven electric vehicles of any type using multiple autonomous mobile robots simultaneously. Moreover, there is a need for a cost- effective system and method for performing a battery exchange without a need for any expensive infrastructure. Furthermore, there is a need for a system and a method for battery exchange without a need for parking electric vehicles with utmost precision. Still furthermore, there is a need for decoupling a battery charging location from a battery exchange location. Yet furthermore, there is a need for a system and a method for determining and resolving malfunctions of equipment used for the battery exchanges in a battery exchange station. Yet there is a need for a system and a method for dynamic and intelligent positioning, movement, and operations of functional components within the battery exchange station for ensuring optimal and simultaneous battery exchange processes.

[0108] The battery collection and delivery system 105 is movable in an upward direction, a downward direction, a frontward direction, a rearward direction, a left side direction, and a right side direction, and the lower portion 105b of the battery collection and delivery system 105 operably connected to the upper portion 105a rotates the upper portion 105a about its own axis to position itself accurately with respect to a destination, for example, a battery compartment 117 of an electric vehicle 116 or, in an embodiment, to position itself accurately with respect to the battery collection point 109 and the battery vending point 110 of the battery rack system 108 shown in FIG. 1 to deposit a spent battery and receive a charged battery respectively. According to an embodiment herein, the autonomous mobile robot 104 and the battery collection and delivery system 105 fitted thereon communicate with one or more sensors, for example, ultrasound sensors, image sensors such as cameras, etc., for accurate positioning within a destination, for example, the battery compartment 117, the battery collection point 109, and the battery vending point 110 of the battery rack system 108 shown in FIG. 1. As exemplarily illustrated in FIG. 3H, a camera 147, for example, a mono camera or a stereo camera, is positioned at a front surface 105e of the upper portion 105a of the battery collection and delivery system 105. The camera 147 captures images of the battery 107 and the battery compartment 117 in the electric vehicle 116. The battery collection and delivery system 105 uses the captured images, the battery information, the electric vehicle information, and the position information received from the battery exchange server 102 and/or the autonomous robot server 103 shown in FIG. 1, to adjust its orientation and inclination to position itself accurately with respect to the electric vehicle 116 to extract the battery 107 from the battery compartment 117 or deposit the battery 107 into the battery compartment 117. The battery collection and delivery system 105 extracts the spent battery from the battery compartment 117 of the electric vehicle 116 and places the spent battery at the battery collection point 109 of the battery rack system 108. The battery collection and delivery system 105 also picks up the fully charged battery from the battery vending point 110 of the battery rack system 108 and fixes the fully charged battery in the battery compartment 117 of the electric vehicle 116.
[0109] According to an embodiment herein, the battery collection and delivery system 105 communicates with the autonomous mobile robot 104 via a wired connection. According to another embodiment herein, the battery collection and delivery system 105 communicates with the autonomous mobile robot 104 via a wireless connection. According to an embodiment herein, the battery collection and delivery system 105 communicates a status of operation, for example, a status of picking up a battery 107 from the battery compartment 117 of the electric vehicle 116 and the battery vending point 110, placement of the battery 107 in the battery compartment 117 of the electric vehicle 116 and the battery collection point 109, etc., to the battery exchange server 102 and/or the autonomous robot server 103. According to an embodiment herein, the battery collection and delivery system 105 communicates a health status of the battery collection and delivery system 105, for example, whether the battery collection and delivery system 105 is fully operational, has malfunctioned, or requires servicing, to the battery exchange server 102, and/or the autonomous robot server 103, and/or the autonomous mobile robot 104 on which the battery collection and delivery system 105 is placed. According to an embodiment herein, the battery collection and delivery system 105 also communicates a status of alignment of the conveyor 144 with respect to the battery compartment 117 of the electric vehicle 116, the battery collection point 109, and the battery vending point 110, etc., to the battery exchange server 102, and/or the autonomous robot server 103, and/or the autonomous mobile robot 104 on which the battery collection and delivery system 105 is placed.
[0110] Consider an example where the autonomous mobile robot 104 and the battery collection and delivery system 105 accurately position themselves for collecting/installing a battery 107 in the battery compartment 117 of the electric vehicle 116. The autonomous robot server 103 sends a command to the autonomous mobile robot 104 to move to a given battery replacement bay, for example, 111a, shown in FIG. 1, where the electric vehicle 116 is parked. The autonomous robot server 103 also sends information regarding the model of the electric vehicle 116 and battery information to the autonomous mobile robot 104. When the autonomous mobile robot 104 receives a command from the autonomous robot server 103, the autonomous mobile robot 104 starts navigating towards the battery replacement bay 111a using its own position/orientation obtained using the indoor/outdoor positioning system (IOPS) tags installed. The autonomous mobile robot 104 also uses the map of the battery exchange station 101 shown in FIG. 1 for this navigation. The autonomous mobile robot 104 reaches the given battery replacement bay 111a. The autonomous mobile robot 104 reaches the destination with an accuracy of few centimetres in distance and few degrees in orientation.
[0111] Once the autonomous mobile robot 104 reaches the destination, the autonomous mobile robot 104 sends a message to the battery collection and delivery system 105 about reaching its destination via a CAN bus. The battery collection and delivery system 105 uses the camera 147 to find its orientation and position with respect to the battery compartment 117 of the electric vehicle 116. The lower portion 105b of the battery collection and delivery system 105 rotates the upper portion 105a of the battery collection and delivery system 105 until the orientation of the upper portion 105a is in alignment with the battery compartment 117 of the electric vehicle 116. Once the orientation alignment is achieved, the lower portion 105b of the battery collection and delivery system 105 moves on the guide rails 130 of the autonomous mobile robot 104 until the horizontal position alignment with the battery compartment 117 using the camera 147 is achieved. The height adjustment mechanism 143, for example, a scissor lift, in the upper portion 105a of the battery collection and delivery system 105 is used for the vertical position alignment with the battery compartment 117 using the camera 147. Once the orientation alignment, the horizontal position alignment, and the vertical position alignment are achieved, the conveyor system 144 on the upper portion 105a of the battery collection and delivery system 105 is aligned appropriately to perform the battery movement operation as required. Once the appropriate alignment is achieved, the battery 107 is moved from/to the conveyor system 144 using the robotic arm 146 of the battery collection and delivery system 105. Similarly, the autonomous mobile robot 104 and the battery collection and delivery system 105 accurately position themselves for collecting a charged battery from the battery vending point 110 of the battery rack system 108 and for depositing a spent battery to the battery collection point 109 of the battery rack system 108.
[0112] FIG. 4 illustrates a perspective view of the battery rack system 108 comprising the battery collection point 109 and the battery vending point 110, according to an embodiment herein. Spent batteries are collected at the battery collection point 109 and stored within the battery rack system 108. The autonomous mobile robots 104 in the battery exchange station 101 transfer the spent batteries from electric vehicles 116 illustrated in FIG. 1, to the battery collection point 109. The collected spent batteries at the battery collection point 109 are placed within the battery rack system 108 for storage and/or, in an embodiment, for charging. According to an embodiment herein, mobile battery rack systems 118 illustrated in FIG. 2, deliver charged batteries to the battery rack system 108 via the battery collection point 109. According to an embodiment herein, the mobile battery rack systems 118 illustrated in FIG. 2, collect empty/spent batteries from the battery rack system 108 via the battery vending point 110. Charged batteries are brought to the battery vending point 110 from within the battery rack system 108 and transferred to the autonomous mobile robots 104 via the battery vending point 110 in the battery rack system 108. According to an embodiment herein, the battery rack system 108 is configured to operate without the battery collection point 109 and the battery vending point 110.
[0113] FIG. 5 illustrates a top plan view of the battery rack system 108 comprising slots 148 arranged as a puzzle parking system, according to an embodiment herein. The slots 148 of the battery rack system 108 are positioned at multiple levels within the battery rack system 108. The slots 148 of the battery rack system 108 store batteries, for example, spent batteries, charged batteries, etc., of different types. According to an embodiment herein, the slots 148 are moved using a multilevel puzzle parking mechanism to convey a required battery to the battery vending point 110 or to store a battery in one of the slots 148. The multilevel puzzle parking mechanism is electromechanically configured to move vertically up to multiple levels and horizontally based on the space available in the battery rack system 108. According to an embodiment herein, the slots 148 are configured to charge the spent batteries stored therein. The multilevel puzzle parking mechanism multiples the capacity of storing the batteries in the battery rack system 108. As illustrated in FIG. 5, the battery rack system 108 comprises multiple conveyors 149. The collected spent batteries at the battery collection point 109 are placed in the slots 148 and moved within the battery rack system 108 for storage and/or, in an embodiment, for charging, using the multilevel puzzle parking mechanism and the conveyors 149 illustrated in FIG. 5. According to an embodiment herein, charged batteries are brought to the battery vending point 110 from the slots 148 within the battery rack system 108 using the multilevel puzzle parking mechanism and the conveyors 149 illustrated in FIG. 5. According to an embodiment herein, batteries are brought to the battery vending point 110 from the slots 148 within the battery rack system 108 or moved from the battery collection point 109 to the slots 148 within the battery rack system 108 manually or using forklifts (not shown).
[0114] The conveyors 149, in operable communication with motors (not shown), convey the spent batteries from the battery collection point 109 to the slots 148 and the charged batteries from the slots 148 to the battery vending point 110. As illustrated in FIG. 5, one level of slots 148a is left empty for receiving spent batteries from the autonomous mobile robots 104 shown in FIG. 1, and/or charged batteries from the mobile battery rack systems 118 shown in FIG. 2. These empty slots 148a are configured as holders for holding the spent batteries or the charged batteries, prior to conveyance of the spent batteries or the charged batteries to available slots 148b within the battery rack system 108. When an autonomous mobile robot 104 deposits a spent battery to the battery collection point 109, the conveyors 149 transfer the spent battery to any one of the empty slots 148a. The multilevel puzzle parking mechanism is then used to convey the spent battery from the empty slot 148a to any one of the available slots 148b. Similarly, the multilevel puzzle parking mechanism also conveys charged batteries from occupied slots 148 where the charged batteries are stored, to the empty slots 148a before the conveyors 149 transfer the charged batteries to the battery vending point 110. The conveyors 149 of the battery rack system 108 communicate with the conveyor system 144 of the battery collection and delivery system 105 shown in FIG. 3H, for transferring the battery to and from the battery collection point 109 and the battery vending point 110 respectively. The conveyors 149 and 144 of the battery rack system 108 and the battery collection and delivery system 105 respectively, are aligned accurately to transfer the battery 107 from the battery collection and delivery system 105 to the battery collection point 109 or from the battery vending point 110 to the battery collection and delivery system 105.
[0115] FIG. 6 illustrates a top plan view of the slots 150, 154, and 155 of the battery rack system 108 shown in FIG. 5, indicating an engagement of a battery 107 into a slot 150, according to an embodiment herein. As illustrated in FIG. 6, the slot 150 comprises magnetic points 151, a positive terminal 152, and a negative terminal 153. The magnetic points 151 allow a firm connection of the battery 107 into the slot 150. The slot 150 further comprises guiding side walls 150a and 150b for guiding the battery 107 into the slot 150. The battery 107 comprises magnetic points 156, a positive terminal 157, and a negative terminal 158. The magnetic points 156 of the battery 107 match with the magnetic points 151 of the slot 150. The magnetic points 151 of the slot 150 are energized and deenergized as required. When the magnetic points 151 of the slot 150 are energized, the magnetic points 151 hold the battery 107 in place within the slot 150. When the conveyors 149 shown in FIG. 5, guide the battery
107 into the slot 150, the magnetic points 156, the positive terminal 157, and the negative terminal 158 of the battery 107 attach to the magnetic points 151, the positive terminal 152, and the negative terminal 153 of the slot 150 respectively. When the magnetic points 151 of the slot 150 are deenergized, the battery 107 is not magnetically attached to the slot 150.
[0116] Consider an example where the battery rack system 108 comprising a computing engine, the slots 148, the conveyors 149, the battery collection point 109, and the battery vending point 110 illustrated in FIG. 5, receives a command from the battery exchange server 102 shown in FIG. 1, to place a fully charged battery at a given battery vending point 110 identified by a battery vending point number. The battery rack system 108 identifies a fully charged battery 107 with the required specifications in one of the slots 148. The battery rack system 108 identifies the battery 107 in a slot, for example, 150, shown in FIG. 6, that is closest to the given battery vending point number in terms of the time taken to move the battery 107. The computing engine of the battery rack system 108 deenergizes the magnetic points 151 in the slot 150 due to which the battery 107 is not held firmly at the slot 150. The computing engine sends signals to various conveyors 149 in the battery rack system
108 to move the battery 107 to the given battery vending point 110. While the battery 107 is moving along a route in the battery rack system 108, the computing engine also receives information on the location of the battery 107 using different sensors along the route. When the battery 107 reaches the required battery vending point 110, the computing engine notifies the battery exchange server 102 shown in FIG. 1, that the required battery 107 is placed at the given battery vending point 110.
[0117] Consider another example where the battery rack system 108 receives a command from the battery exchange server 102 to accept a spent battery 107 placed at the battery collection point 109. The computing engine of the battery rack system 108 identifies the closest slot, for example, 150 shown in FIG. 6, within the battery rack system 108 that is free to accommodate the spent battery 107. The computing engine sends signals to various conveyors 149 in the battery rack system 108 to move the spent battery 107 to the required position within the battery rack system 108. While the spent battery 107 is moving along a route in the battery rack system 108, the computing engine also receives information on the location of the spent battery 107 using different sensors along the route. When the spent battery 107 is proximal to the required destination within the battery rack system 108, the computing engine energizes the magnetic points 151 in the slot 150. The spent battery 107 is moved into the slot 150 using the conveyors 149 and the guiding side walls 150a and 150b of the slot 150. According to an embodiment herein, the guiding side walls 150a and 150b are used to align the spent battery 107 to a charging point (not shown). When the spent battery 107 is proximal to the magnetic points 151 in the slot 150, the spent battery 107 is attracted to the magnetic points 151 and attaches to the magnetic points 151 in the slot 150. During this process, the spent battery 107 is also electrically connected to the charging point if present. Based on the battery information, the computing engine determines a charging mechanism for the spent battery 107. When the spent battery 107 is fully charged, the computing engine updates a list of fully charged batteries held in the battery rack system 108.
[0118] FIG. 7 illustrates a schematic diagram indicating a formation of a single virtual battery rack system 108c, according to an embodiment herein. The battery exchange station 101 shown in FIG. 1, comprises one or more battery rack systems 108a and 108b. When more than one battery rack system is present, the battery rack systems 108a and 108b are connected to each other either by a physical wired connection or a wireless connection. The physical connection between the battery rack systems 108a and 108b comprises, for example, a mechanical connection and/or an electrical connection. The electrical connection between the battery rack systems 108a and 108b is performed, for example, through a recommended standard 485 (RS485) or other modes of electrical connection. According to an embodiment herein, one of the battery rack systems, for example, 108a, acts as a master and the other battery rack systems, for example, 108b, act as slaves sharing information with the master battery rack system 108a. The battery exchange server 102 first authenticates the master battery rack system 108a, and then authenticates each slave battery rack system 108b via the master battery rack system 108a or directly. When the slave battery rack systems, for example, 108b, are authenticated, the master battery rack system 108a receives information from the slave battery rack systems, for example, 108b. The information comprises, for example, the number of batteries in each slave battery rack system 108b, type of batteries, location of the battery rack system 108a or 108b, number of battery vending points and battery collection points in the battery rack systems 108a and 108b, etc. When the master battery rack system 108a receives information from the slave battery rack systems 108b, the master battery rack system 108a creates a single virtual battery rack system 108c and uses the single virtual battery rack system 108c during battery exchange processes in communication with the battery exchange server 102. [0119] FIG. 8 illustrates a map of the battery exchange station 101, according to an embodiment herein. According to an embodiment herein, the battery rack system 108 comprises multiple battery collection points (BCPs) 109 and multiple battery vending points (BVPs) 110 to allow multiple battery exchanges to be performed simultaneously. The battery collection points 109 and the battery vending points 110 are identified, for example, by unique identifiers or identification numbers. The map of the battery exchange station 101 is predetermined. The map is created before the battery exchange station 101 is deployed. The battery exchange server 102 maintains and updates the map as required based on physical changes at the battery exchange station 101. The autonomous robot server 103 shown in FIG. 1, acquires the map from the battery exchange server 102 and sends the map to the autonomous mobile robots 104 shown in FIG. 1. The autonomous robot server 103 ensures that the autonomous mobile robots 104 have the latest map. According to an embodiment herein, the battery exchange station 101 comprises signalling systems, for example, 801a, 801b, 801c, 801d, 801e, and 801f, that provide signals or alerts regarding when the electric vehicles 116 requiring a battery exchange or replacement are allowed to park in the battery replacement bays 111a, 111b, and 111c and when the electric vehicles 116 are allowed to move out of the battery replacement bays 111a, 111b, and 111c after the battery exchange or replacement to ensure safety of personnel at the battery exchange station 101, the autonomous mobile robots 104, etc. The signalling systems, for example, 801a, 801b, 801c, 801d, 801e, and 801f are installed at the battery replacement bays 111a, 111b, and 111c to signal when an electric vehicle 116 is allowed to move in or out of the respective battery replacement bays 111a, 111b, and 111c.
[0120] When an electric vehicle 116 is on the move within the battery exchange station 101, the autonomous robot server 103 ensures that none of the autonomous mobile robots 104 are moving about the battery exchange station 101. The autonomous mobile robots 104 comprise sensors/intelligence to detect obstructions in route. If an autonomous mobile robot 104 detects an obstruction, the autonomous mobile robot 104 stops and waits for the obstruction to move away. If the obstruction does not move away for a customizable period of time, then the autonomous mobile robot 104 recalculates a different route than the original route and moves to the destination through the different route. The autonomous mobile robot 104 receives a command from the autonomous robot server 103 to move to the battery vending point 110 of the battery rack system 108 for picking up a fully charged battery. [0121] Using the map of the battery exchange station 101, the autonomous mobile robot 104 determines a path to the given battery vending point 110. The autonomous mobile robot 104 determines paths in such a way that the autonomous mobile robot 104 starts moving adjacent and parallel to the battery rack system 108 and towards the required battery vending point 110. Using the location information of the battery vending point 110 and markers present at the battery vending point 110, the autonomous mobile robot 104 stops close to the battery vending point 110. Due to an inherent nature of its design, the autonomous mobile robot 104 cannot align accurately with the battery vending point 110. After the autonomous mobile robot 104 stops near a battery compartment 117, the autonomous mobile robot 104 messages the battery collection and delivery system 105 shown in FIG. 1 and FIG. 3H, about stopping near the battery vending point 110. The battery collection and delivery system 105 using its camera 147 shown in FIG. 3H, identifies horizontal, vertical, and orientation alignment discrepancies. The battery collection and delivery system 105 uses the rotor 137 shown in FIG. 3H to correct the orientation. When the orientation is aligned, the battery collection and delivery system 105 uses the guide rails 130 of the autonomous mobile robot 104 shown in FIGS. 3A-3H, and the motor 134 of the motorized linear slider 133 shown in FIGS. 3D-3G to correct the horizontal alignment. When the horizontal alignment is corrected, the battery collection and delivery system 105 uses the height adjustment mechanism 143, for example, a scissor lift, shown in FIG. 3H, to correct the vertical alignment. Correction of the orientation alignment, the horizontal alignment, and the vertical alignment are repeated until required alignment accuracy is met.
[0122] A computing engine of the battery collection and delivery system 105 checks with the battery exchange server 102 on whether a fully charged battery is placed at the battery vending point 110. If a fully charged battery is not placed at the battery vending point 110, the battery collection and delivery system 105 waits until the fully charged battery is placed at the battery vending point 110. The robotic arm 146 of the battery collection and delivery system 105 pulls the battery to the conveyor system 144 on the upper portion 105a of the battery collection and delivery system 105 as illustrated in FIG. 3H. The conveyor system 144 on the upper portion 105a of the battery collection and delivery system 105 also pulls the battery into the battery collection and delivery system 105. When the battery is fully transferred to the battery collection and delivery system 105, the battery collection and delivery system 105 notifies the autonomous mobile robot 104 which in turn notifies the autonomous robot server 103. The autonomous robot server 103 sends details of the battery replacement bay 111a, 111b, or 111c where the autonomous mobile robot 104 should move towards. The autonomous mobile robot 104, using an identifier of the battery replacement bay 111a, 111b, or 111c as the destination, the map of the battery exchange station 101, its own real time location using, for example, an IOPS tag 106b shown in FIG. 1, calculates the path to be taken to the destination battery replacement bay 111a, 111b, or 111c. The autonomous mobile robot 104 navigates through the calculated path and reaches the destination battery replacement bay 111a, 111b, or 111c. The valid paths configured for the autonomous mobile robot 104 are exemplarily illustrated in FIG. 8.
[0123] According to an embodiment herein, one or more autonomous mobile robots 104 are used for extracting a spent battery from an electric vehicle 116 and for fixing a fully charged battery into the electric vehicle 116. For example, one autonomous mobile robot 104 is used for extracting a spent battery from an electric vehicle 116 and another autonomous mobile robot 104 is used for fixing a fully charged battery into the electric vehicle 116. After the battery exchange operation is complete, the electric vehicles 116 exit the battery exchange station 101 through outgoing paths configured in the map of the battery exchange station 101 as exemplarily illustrated in FIG. 8.
[0124] FIG. 9 illustrates a perspective view of a battery 107 to be exchanged by an autonomous mobile robot 104 shown in FIG. 1 and FIGS. 3A-3C, according to an embodiment herein. The battery 107 comprises magnetic points 156, a positive terminal 157, and a negative terminal 158 as illustrated in FIG. 9. The magnetic points 156 are used to align and secure the battery 107 within a battery compartment 117 of an electric vehicle 116 as shown in FIG. 3H, and within a slot 150 in the battery rack system 108 as shown in FIG. 6.
[0125] FIG. 10A illustrates a side elevation view of an electric vehicle 116, indicating a position of a battery compartment 117, according to an embodiment herein. FIG. 10B illustrates a front elevation view of the battery compartment 117 of the electric vehicle
116, according to an embodiment herein. The battery compartment 117 comprises a connection panel 159 with magnetic points 160, a positive terminal 161, and a negative terminal 162. The connection panel 159 allows an electrical connection to the battery 107 illustrated in FIG. 9. The magnetic points 156 of the battery 107 match with the magnetic points 160 of the connection panel 159. The magnetic points 160 of the connection panel 159 are energized and deenergized as required. When the magnetic points 160 of the connection panel 159 are energized, the magnetic points 160 hold the battery 107 in place within the battery compartment 117. When the conveyor system 144 of the battery collection and delivery system 105 shown in FIG. 3H, guides the battery 107 into the battery compartment
117, the magnetic points 156, the positive terminal 157, and the negative terminal 158 of the battery 107 attach to the magnetic points 160, the positive terminal 161, and the negative terminal 162 of the connection panel 159 in the battery compartment 117 respectively. When the magnetic points 160 of the connection panel 159 are deenergized, the battery 107 is not magnetically attached to the connection panel 159 in the battery compartment 117.
[0126] FIGS. 11A-11E illustrate alignment and positioning of a battery 107 within a battery compartment 117 of an electric vehicle 116 shown in FIG. 10A, according to an embodiment herein. Consider an example where the autonomous mobile robot 104 receives a command from the autonomous robot server 103 shown in FIG. 1, to move to a battery replacement bay, for example, 111a shown in FIG. 8, for extracting a spent battery from a battery compartment 117 of an electric vehicle 116 or depositing a fully charged battery into the battery compartment 117. The autonomous mobile robot 104 calculates a path to traverse to reach the battery replacement bay 111a using an identifier of the battery replacement bay 111a as the destination, the map of the battery exchange station 101, and its real time location, for example, using IOPS tags. The autonomous mobile robot 104 determines paths in such a way that the autonomous mobile robot 104 starts moving adjacent and parallel to the battery replacement bay 111a as illustrated in FIG. 8.
[0127] Using the electric vehicle information sent by the autonomous robot server 103 and markers present in the electric vehicle 116 for the battery compartment 117 or the battery 107, the autonomous mobile robot 104 stops close to the battery compartment 117. Due to an inherent nature of its design, the autonomous mobile robot 104 cannot align accurately with the battery compartment 117. After the autonomous mobile robot 104 stops near the battery compartment 117, the autonomous mobile robot 104 messages the battery collection and delivery system 105 about stopping near the battery compartment 117. The battery collection and delivery system 105, using its camera 147, identifies horizontal, vertical, and orientation alignment discrepancies as illustrated in FIG. 11A. The battery collection and delivery system 105 uses the rotor 137 shown in FIG. 3H to correct orientation as illustrated in FIG. 11B. The rotor 137 rotates the upper portion 105a of the battery collection and delivery system 105 to align itself with respect to the battery compartment 117 as illustrated in FIG. 11B. When the orientation is aligned, the battery collection and delivery system 105 uses the guide rails 130 on the autonomous mobile robot 104 shown in FIGS. SA SH and the motor 134 of the motorized linear slider 133 shown in FIGS. 3D-3G to move in a horizontal direction to align itself with the battery compartment 117 and correct the horizontal alignment as illustrated in FIG. 11C.

According to an embodiment herein, the communication module 103d communicates a malfunction of any one or more of the autonomous mobile robots 104 to the battery exchange server 102. According to an embodiment herein, the scheduler 103e conveys a battery exchange status of the autonomous mobile robots 104 to the battery exchange server 102 and receives commands from the battery exchange server 102 for facilitating an initiation of an exchange of a spent battery with a charged battery into an electric vehicle 116 by the selected autonomous mobile robot 104. The scheduler 103e of the autonomous robot server 103 determines which autonomous mobile robot 104 is to be used to execute the battery exchange commands received from the battery exchange server 102. The scheduler 103e determines which autonomous mobile robots 104 are performing battery exchange tasks such as extraction of a spent battery from an electric vehicle 116, deposit of a spent battery into the battery rack system 108, pick up of a charged battery from the battery rack system 108, fixing of the charged battery into a battery compartment 117 of the battery rack system 108 shown in FIG. 1, etc., and which autonomous mobile robots 104 are free at any given time. If all the autonomous mobile robots 104 in the battery exchange station 101 shown in FIG. 1, are occupied in performing battery exchange tasks, the scheduler 103e identifies a sequence of availability of the autonomous mobile robots 104 for performing additional battery exchange tasks based on an estimated time of completion of the battery exchange tasks by each of the autonomous mobile robots 104.

The autonomous vehicle subsystem (AVS) comprising the autonomous robot server 103 and the autonomous mobile robots 104 execute the battery exchange tasks sequentially or in parallel.
[0144] Consider an example where the autonomous vehicle subsystem is configured to perform the two battery exchange tasks sequentially. When the battery exchange server
102 sends a command about a subsequent battery exchange to the autonomous robot server
103 in the autonomous vehicle subsystem, the scheduler 103e receives the command for the spent battery collection task. The autonomous robot server 103 gathers information on the current status of all the autonomous mobile robots 104 in the autonomous vehicle subsystem. The autonomous robot server 103 gathers information on the number of free slots in the battery rack system 108 that are configured to accommodate the spent battery from the battery rack system 108. For each free slot, the autonomous robot server 103 also collects its location and the time taken to move the spent battery from the nearest battery collection point 109 to the free slot. The scheduler 103e receives the above information and identifies the autonomous mobile robot 104 and the battery collection point 109 such that the spent battery collection task is completed in a short time. The autonomous robot server 103 notifies the battery exchange server 102 regarding the identified autonomous mobile robot 104 and the battery collection point 109 for the spent battery collection task.
[0145] The battery exchange server 102, in turn, notifies the battery rack system 108 regarding the battery collection point 109 identified for the spent battery collection task. When the autonomous mobile robot 104 completes the spent battery collection task, the autonomous mobile robot 104 notifies the autonomous robot server 103 that in turn, notifies the battery exchange server 102. The battery exchange server 102 notifies the battery rack system 108 that the spent battery is placed in the battery collection point 109. When the spent battery collection’ task is completed, the scheduler 103e receives a command for the battery replenishment task. The autonomous robot server 103 gathers information on the current status of all the autonomous mobile robots 104 in the autonomous vehicle subsystem. Moreover, the autonomous robot server 103 gathers information on the number batteries of a required type available from the battery rack system 108. For each one of the batteries available, the autonomous robot server 103 also gathers information on its location, time taken to move the battery to the nearest battery vending point 110, etc. The scheduler 103e receives the above information and identifies the autonomous mobile robot 104 and the battery vending point 110 such that the battery replenishment task is completed in a short time. The autonomous robot server 103 notifies the battery exchange server 102 regarding the identified autonomous mobile robot 104 and the battery vending point 110 for the battery replenishment task. The battery exchange server 102, in turn, notifies the battery rack system 108 regarding the battery vending point 110 identified for the battery replenishment task. When the autonomous mobile robot 104 collects the battery from the battery vending point 110, the autonomous mobile robot 104 notifies the autonomous robot server 103 that in turn, notifies the battery exchange server 102. The battery exchange server 102 notifies the battery rack system 108 that the battery is collected from the battery vending point 110. When the autonomous mobile robot 104 completes the battery replenishment task in the electric vehicle 116, the autonomous mobile robot 104 notifies the autonomous robot server 103 that in turn, notifies the battery exchange server 102.
[0146] Consider another example where the autonomous vehicle subsystem is configured to perform the two battery exchange tasks in parallel. In this example, the scheduler 103e receives commands for both the spent battery collection task and the battery replenishment task at the same time. The autonomous robot server 103 collects similar information from the autonomous mobile robots 104 and the battery rack system 108 as disclosed above. The scheduler 103e uses this information and identifies one combination of an autonomous mobile robot 104 and a battery collection point 109 for executing the spent battery collection task and another combination of an autonomous mobile robot 104 and a battery vending point 110 for executing the battery replenishment task. The autonomous robot server 103 sends information on the identified autonomous mobile robots 104, the battery collection point 109, and the battery vending point 110 to the battery exchange server 102 that in turn, sends the required information to the battery rack system 108. In this example, the autonomous mobile robots 104 execute the battery exchange tasks in parallel with the exception of the spent battery collection from the electric vehicle 116 and replenishment of the fully charged battery into the electric vehicle 116.

The battery rack system 108 receives a command to place a fully charged battery of a given type at the battery vending point 110. When the fully charged battery is placed in the battery vending point 110.

[0158] FIG. 15 illustrates a flowchart explaining a method for exchanging spent batteries with charged batteries in multiple electric vehicles simultaneously. According to an embodiment herein, the method disclosed herein comprises configuring 1501 the battery exchange server 102, multiple battery replacement bays 111a, 111b, 111c, llld, llle, and lllf, multiple battery rack systems 108, multiple autonomous mobile robots 104, and the battery collection and delivery system 105 in a battery exchange station 101 as illustrated in FIG. 1. According to an embodiment herein, the method disclosed herein further comprises the following steps: The battery exchange server 102, in communication with the central server 115 shown in FIG. 1, determines 1502 a demand for charged batteries and delivers supplementary charged batteries to the battery rack systems 108 based on the demand. The battery exchange server 102 detects 1503 one or more electric vehicles 116 parked in any position at any one or more of the battery replacement bays 111a, 111b, 111c, llld, llle, and lllf illustrated in FIG. 1. The battery exchange server 102, in communication with the autonomous robot server 103, selects 1504 one or more of the autonomous mobile robots 104 to perform an exchange of the spent battery with the charged battery in the detected electric vehicle 116.
[0159] The battery exchange server 102, in communication with the autonomous robot server 103, identifies 1505 a charged battery slot and a spent battery slot from the slots in one or more of the battery rack systems 108. The charged battery slot is configured to receive and store the charged battery to be picked up by the selected autonomous mobile robot 104. The spent battery slot is configured to receive and store the spent battery from the selected autonomous mobile robot 104. The battery exchange server 102 receives and communicates 1506 battery information and position information from the detected electric vehicle 116 to the selected autonomous mobile robot 104. The selected autonomous mobile robot 104 traverses 1507 a first path to the battery replacement bay, for example, 111a, where the detected electric vehicle 116 is parked. The selected autonomous mobile robot 104, in communication with one or more sensors, positions and aligns 1508 the battery collection and delivery system 105 with respect to the battery compartment 117 of the detected electric vehicle 116 as illustrated in FIG. 3H, to extract the spent battery using the position information. The selected autonomous mobile robot 104 traverses 1509 a second path to the battery rack system 108 with the spent battery. The battery collection and delivery system 105 on the selected autonomous mobile robot 104, in communication with one or more sensors, aligns and positions 1510 the spent battery in the spent battery slot of the battery rack system 108.
[0160] The selected autonomous mobile robot 104 positions and aligns 1511 the battery collection and delivery system 105, in communication with one or more sensors, in the charged battery slot of the battery rack system 108 to extract the charged battery. The selected autonomous mobile robot 104 traverses 1512 a third path to the battery replacement bay 111a where the electric vehicle 116 is parked with the charged battery. The battery collection and delivery system 105 on the selected autonomous mobile robot 104, in communication with one or more sensors, aligns and positions 1513 the charged battery into the battery compartment 117 of the electric vehicle 116 based on the position information.
[0161] Consider an example where an electric vehicle 116 is parked at a battery replacement bay, for example, llle, as illustrated in FIG. 1 and FIG. 12. A driver of the electric vehicle 116 flashes or scans an RFID based subscription card near the RFID reader 112e illustrated in FIG. 1. The RFID based subscription card comprises details of the electric vehicle 116 and the type of battery used in the electric vehicle 116. The driver verifies the details of the electric vehicle 116 on a display unit of the battery replacement bay llle and requests for a battery exchange through the RFID reader 112e. When the driver flashes the RFID based subscription card, the RFID reader 112e reads the details of the electric vehicle 116 and sends the battery exchange request and the details of the electric vehicle 116 to the battery exchange server 102 along with an identifier of the battery replacement bay llle at which the electric vehicle 116 is parked. Though the electric vehicle 116 is parked at the battery replacement bay llle, the driver need not park/position the electric vehicle 116 accurately. The battery replacement bay module 102f of the battery exchange server 102 illustrated in FIG. 12, receives and sends the battery exchange request to the processor 102a configured as a control and monitoring engine. The processor 102a validates the authenticity of the battery exchange request and forwards the battery exchange request to the autonomous mobile robot module 102d illustrated in FIG. 12. The autonomous mobile robot module 102d sends the battery exchange request to the autonomous robot server 103 with details of the electric vehicle 116 and the identifier of the battery replacement bay llle where the electric vehicle 116 is parked. [0162] The autonomous robot server 103 gathers information on the status of all the autonomous mobile robots 104 and their availability. The autonomous robot server 103 also collects information from the battery rack system 108 on empty slots and time taken to move a spent battery from the battery collection point 109 shown in FIG. 5, to a proximal empty slot. Using the above information, the scheduler 103e in the autonomous robot server 103 determines and selects the autonomous mobile robot 104 and the battery collection point 109 where the spent battery will be deposited or placed. The autonomous robot server 103 sends a command to the selected autonomous mobile robot 104 to perform a spent battery collection task. The autonomous mobile robot 104, using its current location, a map of the battery exchange station 101, its real-time location using IOPS tags, navigates to the battery replacement bay llle where the electric vehicle 116 is parked. After reaching the required location, the autonomous mobile robot 104 sends a message to the battery collection and delivery system 105. The battery collection and delivery system 105 uses the camera 147, the wheels 135, the rotor 137, and the height adjustment mechanism 143, for example, the scissor lift, illustrated in FIG. 3H, to perform a positional and orientation alignment with respect to a battery compartment 117 of the electric vehicle 116. The battery collection and delivery system 105 uses its robotic arm 146 illustrated in FIG. 3H, to pull the spent battery from the battery compartment 117 and place the spent battery on its conveyor system 144 illustrated in FIG. 3H. The motorised conveyor system 144 pulls the spent battery until the spent battery is fully placed on the conveyor system 144. The battery collection and delivery system 105 notifies the autonomous mobile robot 104 that the spent battery is fully collected. The autonomous mobile robot 104 navigates to the mentioned battery collection point 109 of a given battery rack system 108. The battery collection and delivery system 105 uses the camera 147, the wheels 135, the rotor 137, and the height adjustment mechanism 143 to perform a positional and orientation alignment with respect to the battery collection point 109. The battery collection and delivery system 105 uses the robotic arm 146 to push the spent battery from the conveyor system 144 to the battery collection point 109. The battery collection and delivery system 105 notifies the autonomous mobile robot 104 that the spent battery is placed in the battery collection point 109. The autonomous mobile robot 104 notifies the autonomous robot server 103 which in turn, notifies the battery exchange server 102, thereby completing the spent battery collection task of the battery exchange.
[0163] For the battery replenishment task of the battery exchange, the autonomous robot server 103 gathers information on the status of all the autonomous mobile robots 104 and their availability. The autonomous robot server 103 also collects information, for example, availability of batteries of a required type at the battery rack system 108 and time taken to move the spent battery from the battery collection point 109 to a proximal empty slot. Based on the above information, the scheduler 103e determines and selects the autonomous mobile robot 104 and the battery vending point 110 shown in FIG.1, FIG.5, and FIG.8, where a fully charged battery is made available. The autonomous robot server 103 sends a command to the selected autonomous mobile robot 104 to perform a pickup of the fully charged battery from the given battery vending point 110. The selected autonomous mobile robot 104, using its current location, the map of the battery exchange station 101, its real-time location using IOPS tags, etc., navigates to the given battery vending point 110. After reaching the required location, the selected autonomous mobile robot 104 sends a message to the battery collection and delivery system 105. The battery collection and delivery system 105 uses the camera 147, the wheels 135, the rotor 137, and the height adjustment mechanism 143, for example, the scissor lift, to perform a positional and orientation alignment with respect to the battery vending point 110. The battery collection and delivery system 105 uses the robotic arm 146 to pull the charged battery from the battery vending point 110 and place the charged battery on its conveyor system 144. The motorized conveyor system 144 pulls the charged battery until the charged battery is fully placed in the conveyor system 144. The battery collection and delivery system 105 notifies the autonomous mobile robot 104 that the charged battery is fully collected. The autonomous mobile robot 104 navigates to the electric vehicle 116 at the battery replacement bay llle. The battery collection and delivery system 105 uses the camera 147, the wheels 135, the rotor 137, and the height adjustment mechanism 143, for example, the scissor lift, to perform a positional and orientation alignment with respect the battery compartment 117 of the electric vehicle 116. The battery collection and delivery system 105 uses the robotic arm 146 to push the charged battery from the conveyor system 144 to the battery compartment 117 of the electric vehicle 116. The battery collection and delivery system 105 notifies the autonomous mobile robot 104 that the charged battery is placed in the battery compartment 117 of the electric vehicle 116. The autonomous mobile robot 104 notifies the autonomous robot server 103 which in turn, notifies the battery exchange server 102, thereby completing the battery replenishment task of the battery exchange.
[0164] The battery exchange station 101 disclosed herein does not require expensive infrastructure for battery exchange. Moreover, the battery collection and delivery system 105 operably coupled to each of the autonomous mobile robots 104 allows optimal alignment and positioning of the battery into a battery compartment 117 of an electric vehicle 116, without requiring the electric vehicle 116 to be parked accurately with utmost precision at one of the battery replacement bays 111a, 111b, 111c, llld, llle, and lllf. Since the battery is not as heavy as the electric vehicle 116, positioning the battery into the electric vehicle 116 is not a difficult and expensive task. Furthermore, since accurate parking of the electric vehicle 116 is not required and the battery is conveyed back and forth between the battery rack system 108 and the electric vehicle 116 using the autonomous mobile robots 104, there is substantial flexibility in the number of electric vehicles 116 serviced at a given time. Due to the lower weight of the autonomous mobile robots 104, and hence low inertia when compared with the electric vehicles 116, positioning of the autonomous mobile robots 104 with respect to the electric vehicles 116 and the battery rack systems 108 is performed with ease in the system 100 and the method disclosed herein. If any one of the autonomous mobile robots 104 malfunctions, the central server 115 delivers another autonomous mobile robot 104 from a nearby battery exchange station 101, thereby allowing battery exchange to continue with remaining or replacement autonomous mobile robots. The battery exchange station 101 disclosed herein has a lower cost of infrastructure, is scalable based on demand, allows exchange of multiple batteries for multiple electric vehicles 116 at the same time, decouples battery charging, battery storage, and battery exchange operations, and provides flexibility to manage logistics of supply and demand.
[0165] The various embodiments herein allow accurately positioning of an autonomous mobile robot 104 for battery exchange rather than accurate positioning of an electric vehicle 116. Thus, the driver of the electric vehicle 116 need not have to park the electric vehicle 116 with utmost precision. The battery exchange station 101 and its components and subsystems are scalable in nature in accordance with demand for battery exchange at the battery exchange station 101. The system disclosed herein decouples a battery charging location from the location where the battery is exchanged, thereby providing flexibility to charge batteries at a central location and providing a means to meet supply and demand dynamically. Further, the various embodiments herein allow exchange of batteries in multiple electric vehicles 116 at the same time. The system disclosed herein is also flexible in a manner that even if one of the autonomous mobile robots 104 malfunctions, battery exchange is continued with remaining autonomous mobile robots and/or replacement autonomous mobile robots are issued to the battery exchange station 101 quickly.
