[0012] As briefly described above, a battery charging station, a method executed by a computing system integrated with the control system of the battery charging station, and a computing system for controlling the operation of the battery charging station are disclosed. The disclosed battery charging station, method, and computing system can receive health status data from a mobile platform via a wireless communication link. The health status data can indicate the health status of the mobile platform's battery system. Before and during charging operations, the health status data can be evaluated at the charging station or by the charging station to determine whether charging of the mobile platform's battery system by the charging station should be enabled or disabled. If the health status data indicates a failure in the mobile platform's battery system, the charging station can perform one or more remedial operations, including, for example, disabling charging, disconnecting from the mobile platform, alerting emergency services, alerting maintenance services, and activating fire suppression.
[0013] The battery charging station, method, and computing system disclosed herein offer the potential to address various challenges or problems related to charging batteries located on mobile platforms. For example, mobile platforms can take the form of electric or hybrid electric vehicles (such as cars, trucks, buses, aircraft, scooters, and motorcycles). Charging electric and hybrid electric vehicles can lead to overheating or fire / damage events if a fault or failure occurs in the battery system during charging operations. There is a global problem whereby an increasing number of rechargeable vehicles may endanger people and property when high-voltage battery systems short-circuit and progress to thermal runaway conditions. For example, the resulting arcing and fire conditions can be fatally hazardous and cause property damage. Currently, there is no known solution to connect a mobile platform to a charging station in a way that enables the charging station to respond to faults within the mobile platform. The battery charging station, method, and computing system disclosed herein enable the charging station to perform a series of remedial operations in response to a fault detected within the battery system of the mobile platform.
[0014] Figure 1 This is a schematic diagram depicting a battery charging system 100 including a battery charging station 110. The battery charging system 100 also includes one or more mobile platforms containing onboard batteries that can be charged by the charging station 110. Figure 1 An example mobile platform 112 is depicted. For example, the mobile platform 112 may take the form of a vehicle. However, the mobile platform 112 may take the form of other machines or equipment.

In some examples, supply cable 149 can form part of electrical system 130. In other examples, supply cable 149 can be connected to charging interface 140 via power outlet or other suitable connector.
[0019] The electrical system 130 may also include an electrical processing component 142. In at least some examples, electrical energy 148 supplied by the power supply infrastructure 116 may be processed by the electrical processing component 142 to obtain electrical energy 144 in a form suitable for supplying to the mobile platform 112. For example, the electrical processing component 142 processing the electrical energy 148 to obtain electrical energy 144 may include one or more of the following: voltage processing (e.g., increasing, decreasing, buffering, filtering), current processing (e.g., increasing, decreasing, buffering, filtering), alternating current to direct current (AC / DC) conversion, and direct current to direct current (DC / DC) conversion.

Additionally or alternatively, communication system 132 includes a wired interface 152 that supports wired communication with remote devices via a physical wired communication link (e.g., copper wire, fiber optic cable, etc.) through one or more wired communication protocols. Charging station 110 can utilize wireless interface 150 and / or wired interface 152 to communicate with mobile platform 112, emergency service infrastructure 118, maintenance service infrastructure 120, network resources 122, fire suppression system 124, and user equipment 126 via communication network 114.
[0021] The control system 134 is operable to control various aspects of the charging station 110, including the electrical system 130 and the communication system 132. In some examples, the control system 134 may include one or more computing devices forming a computing system. Figure 1 The user interface 154 is schematically depicted. In some examples, the control system 134 may receive user input via the user interface 154. Furthermore, in some examples, the user interface 154 may take the form of a graphical user interface (GUI), which may be displayed via a display device integrated with or surrounding the charging station 110. For example, the control system 134 may provide the user interface 154 to a remote device (e.g., user equipment 126 or mobile platform 112) via a wireless interface 150 or a wired interface 152 through a communication network 114.
[0022] Mobile platform 112 includes a battery system 160 comprising one or more batteries. Mobile platform 112 also includes a charging interface 162 through which the mobile platform can receive electrical energy 144 supplied by charging station 110 to charge the batteries in battery system 160. Mobile platform 112 may also include a battery management system 164 that controls the operation of battery system 160 and charging interface 162. Mobile platform 112 may also include a communication system 168 that supports wireless communication with other devices via communication network 114. Mobile platform 112 may also include a platform management system 166 that controls the operation of the mobile platform and its various components (including components not controlled by battery management system 164). Battery management system 164 and platform management system 166 may together form control system 167 of mobile platform 112.
[0023] Emergency service infrastructure 118 may include equipment used by emergency services such as fire, ambulance, and police services to receive and respond to emergency service messages, including requests for emergency services. For example, charging station 110 may send emergency service messages to emergency service infrastructure 118 via communication system 132 through wireless and / or wireless communication links of communication network 114. In some examples, emergency service infrastructure 118 may be located off-site, away from charging station 110.
[0024] Maintenance service infrastructure 120 may include equipment utilized by maintenance services to receive and respond to maintenance service messages, including requests for maintenance services. For example, charging station 110 may send maintenance service messages to maintenance service infrastructure 120 via communication system 132 through wireless and / or wireless communication links of communication network 114. In some examples, maintenance service infrastructure 120 may be located off-site, away from charging station 110.
[0025] Network resource 122 may include one or more server systems, examples of which are shown in Figure 1 It is described as server system 170. Figure 1 In the example, server system 170 has one or more computer-executable programs 172 and other data 174 stored thereon. In some examples, network resources 122, including example server system 170, can facilitate communication between charging station 110 and mobile platforms and user equipment (including...). Figure 1 Communication between the charging station 110 and the mobile platform 112 and / or user equipment 126 is an example. For instance, the control system 134 of the charging station 110 may request and receive one or more programs stored in program 172 at the server system 170. In this example, the control system 134 may execute the program received from the server system 170 as part of communicating with and interpreting data from the mobile platform 112 and / or user equipment 126. Additionally or alternatively, in some examples, communication between the charging station 110 and the mobile platform 112 and / or user equipment 126 may traverse the server system 170. In some examples, network resources 122 including the server system 170 may be located off-site, away from the charging station 110.
[0026] Fire suppression system 124 may include one or more devices operable to provide a fire suppression response 176 to a target area. Fire suppression response 176 may include a dispensed extinguishing agent, such as water, other suitable liquids, or gases. The target area for the fire suppression response may include an area near charging station 110 occupied by mobile platform 112 during charging operation of battery system 160. Control system 134 may communicate with fire suppression system 124 via communication network 114 through wireless interface 150 or wired interface 152 to request fire suppression response 176.
[0027] User equipment 126 may take the form of a mobile computing device (e.g., a smartphone or handheld computer) that can be operated by a user associated with mobile platform 112. In some examples, user equipment 126 may be user-operable to communicate with some or all of the control system 134 of charging station 110, mobile platform 112, and network resources 122 (including server system 170). For example, a user may operate user equipment 126 to initiate and control various aspects of the charging operation provided by charging station 110 to mobile platform 112. Furthermore, in some examples, user equipment 126 may serve as a user interface for control system 134.
[0028] Communication network 114 may include one or more personal area networks (PANs), one or more local area networks (LANs), and one or more wide area networks (WANs) (e.g., cellular networks and / or the Internet), as well as associated network devices that facilitate network communication.

Communication network 114 may include one or more wired communication networks that support communication via one or more wired communication links using one or more wired communication protocols.
[0029] As an example, charging station 110 may utilize wireless interface 150 to wirelessly communicate with mobile platform 112 (and similarly with user equipment 126) via wireless communication link 180 through a wireless personal area network utilizing the Bluetooth™ wireless communication protocol, a wireless local area network utilizing the Wi-Fi™ wireless communication protocol, or a wireless wide area network utilizing a cellular wireless communication protocol (e.g., 4G / LTE). As another example, charging station 110 may utilize communication system 132 to communicate with fire suppression system 124 via a wireless or wired communication link through communication network 114. As an additional example, charging station 110 may utilize communication system 132 to communicate with emergency service infrastructure 118, maintenance service infrastructure 120, and network resources 122 (including server system 170) via wireless and / or wired wide area networks through communication network 114.
[0030] Figure 2 , Figure 3 and Figure 4 This is a flowchart depicting example method 200. For example, method 200 can be... Figure 1 It executes within the context of the battery charging system 100. (See reference...) Figure 2 The process flow 210 of method 200 is executed by the control system 134 of the charging station 110, as previously referred to Figure 1 As described in further detail herein, the control system 134 of the charging station 110 may include a computing system 220 configured to execute process flow 210 of method 200. In this example, the computing system 220 has one or more programs 230 and data 232 stored thereon. The one or more programs 230 may be executed by the computing system 220 of the charging station 110 to execute process flow 210.
[0031] Additionally, process flow 212 of method 200 is executed by the mobile platform, for example by the control system 167 of the mobile platform 112, which includes a battery management system 164 and a platform management system 166, as previously referenced. Figure 1 The control system 167 of the mobile platform 112 includes a computing system 222 on which one or more programs 234 and data 236 are stored. The one or more programs 234 can be executed by the computing system 222 to perform process flow 212.
[0032] At 240 in process flow 210, charging station 110 operates in an idle state. The idle state can correspond to an operating mode of charging station 110 implemented when the charging station is not interacting with a mobile platform (such as mobile platform 112). For example, the idle state can take the form of a power-saving operating mode. When operating in the idle state at 240, charging station 110 can put wireless interface 150 into a listening mode, in which the charging station monitors charging requests from the mobile platform.
[0033] In process flow 210 at 242, charging station 110 receives an operation to initiate battery charging of battery system 160 of mobile platform 112. Figure 3 The charging request 244 (331) is received via the user interface 154 of the charging station 110 (e.g., as user input) or via the communication network 114 of the charging station 110 communication system 132 (e.g., as a message initiated by the mobile platform 112 or user equipment 126). For example, the charging request 244 can be received wirelessly via the wireless interface 150 or wiredly via the wired interface 152. In some examples, the charging request may include or be accompanied by a mobile platform identifier identifying the mobile platform 112.
[0034] In process flow 210 at 246, charging station 110 transitions from an idle state to an active state in response to receiving charging request 244 at 242. The active state may correspond to the operating mode of charging station 110 implemented when the charging station interacts with a mobile platform (such as mobile platform 112). As part of the active state, charging station 110 may be established at process flow 210 at 248. Figure 1 The wireless communication link 180 between the mobile platform 112 and the mobile platform 112.
[0035] As established in 248 Figure 1 As part of the wireless communication link 180, charging station 110 and mobile platform 112 may negotiate the wireless communication link at 250 of process flow 210 and 252 of process flow 212, respectively. For example, negotiating the wireless communication link 180 may include charging station 110 and mobile platform 112 selecting and implementing each other's sets of technical features according to a wireless communication protocol (such as Bluetooth™ or Wi-Fi™). Negotiating the wireless communication link 180 may include charging station 110 exchanging wireless communications with mobile platform 112 via wireless interface 150 through a personal area network or local area network of communication network 114. Furthermore, in some examples, charging station 110 may select a wireless communication protocol from a set of wireless communication protocols supported by both charging station and mobile platform for subsequent wireless communication with mobile platform 112. Alternatively or additionally, mobile platform 112 may select a wireless communication protocol from a set of wireless communication protocols supported by both charging station and mobile platform for subsequent wireless communication with charging station 110.
[0036] At 254, charging station 110 was confirmed. Figure 1 Has the wireless communication link 180 with the mobile platform 112 been successfully established? If the wireless communication link has not been successfully established ( Figure 2 If the value is "No", then the charging station 110 can attempt to establish a wireless communication link with the mobile platform 112 a certain number of times in 256 steps. Figure 2 The threshold value represented by the term "X" can be any suitable value greater than or equal to 1. If the wireless communication link has not been successfully established after the threshold value has been reached, the charging station 110 can remind the maintenance service by sending a message to the maintenance service infrastructure 120 via the communication network 114 through the wireless interface 150 or wired interface 152 of the communication system 132 at 258.
[0037] Successfully established at charging station 110 Figure 1 After the wireless communication link 180 with the mobile platform 112 ( Figure 2In the context of the "Yes" sign, the charging station and the mobile platform can negotiate a health status report via a wireless communication link at 260 of process flow 210 and 262 of process flow 212, respectively. As part of negotiating the health status report at 260, the charging station 110 can determine one or more of the platform type 266 of the mobile platform 112 and the reporting protocol 268 used by the mobile platform to report the health status at 264. For example, the charging station 110 can send a request for platform type 266 and / or reporting protocol 268 to the mobile platform 112 via the wireless communication link, and the mobile platform can respond to the request by sending one or more messages to the charging station via the wireless communication link, indicating the platform type and / or reporting protocol. In the example where the mobile platform 112 provides platform type 266, the charging station 110 can refer to locally stored data 232 or data 236 remotely stored at network resource 122 via communication network 114 to identify the reporting protocol 268 based on platform type 266.
[0038] At 270, charging station 110 identifies a subject program for platform type 266 and / or reporting protocol 268 for mobile platform 112. If the subject program identified at 270 exists in program 230 stored locally at charging station 110, the charging station can execute the subject program at 272. If the subject program identified at 270 does not exist in program 230, the charging station can request and receive the subject program from one or more network resources 122 via wireless interface 150 or wired interface 152 in communication network 114 (e.g., Figure 2 (Program 271 in the network resource 122). The program received from the network resource 122 can be added to program 230 at computing system 220, and can be executed by computing system 220 at 272.
[0039] The subject program executed by computing system 220 at 272 can be used by charging station 110 to request, receive, and interpret health status data reported by mobile platform 112 according to reporting protocol 268. For example, at 274 of process flow 210, charging station 110 can request and receive initial health status data 276 from mobile platform 112 via wireless communication link 180. Initial health status data 276 can be formatted according to reporting protocol 268. In this example, initial health status data 276 can be provided by mobile platform 112 as part of the initial health status reporting process at 278 of process flow 212. As part of the initial health status report at 278, mobile platform 112 can obtain initial health status data 276 at least in part based on measurements from battery system 160 from onboard sensors, and can report the initial health status data to charging station 110 via wireless communication link 180 at 280.
[0040] Initial health status data 276 can indicate the operating conditions of the battery system 160 of the mobile platform 112. For example, the operating conditions of the battery system 160 may include one or more of the following: voltage, current, power, and / or temperature of the battery system or its battery modules (module-specific operating conditions). Reference Figures 5-8 Examples of operating conditions that the mobile platform 112 can measure and report are described in more detail. As another example, initial health status data 276 can indicate a fault in the battery system 160 detected by the mobile platform 112 (e.g., through initial health status data including a fault identifier).
[0041] refer to Figure 3 In process flow 210 at 310, charging station 110 may evaluate initial health status data 276 received from mobile platform 112 via wireless communication link 180. As part of evaluating initial health status data 276 at 310, charging station 110 may determine at 312 whether initial health status data 276 meets first conditions instructing satisfactory operation of battery system 160 of mobile platform 112.
[0042] For example, the computing system 220 of charging station 110 may at 312 compare initial health state data 276 with one or more thresholds to determine whether a first condition is met. In this example, the values of voltage, current, power, and / or temperature of battery system 160 or battery modules of the battery system (specific to module operating conditions) identified by initial health state data 276 may be compared with one or more thresholds defined by program 271 or other programs executed by computing system 220 within program 230. Additionally or alternatively, at 312, charging station 110 may assess the absence of a fault or fault identifier in initial health state data 276 as meeting the first condition. The first condition assessed at 312 may include a combination of two or more thresholds applied to two or more of the following: voltage, current, power, and / or temperature of battery system 160 or battery modules of the battery system, and the assessment of the thresholds may be combined to consider the presence or absence of a fault indicated by initial health state data 276.
[0043] Additionally or alternatively, as part of the evaluation of the initial health status data 276 at 310, the charging station 110 may determine at 314 whether the initial health status data meets a second condition indicating unsatisfactory operation (e.g., malfunction) of the battery system 160 of the mobile platform 112.
[0044] For example, the computing system 220 of charging station 110 may at 314 compare the initial health state data 276 with one or more thresholds to determine whether a second condition is met. In this example, the values of voltage, current, power, and / or temperature of the battery system 160 or its battery modules (specific to module operating conditions) identified by the initial health state data 276 may be compared with one or more thresholds defined by program 271 or other programs executed by computing system 220 within program 230. Additionally or alternatively, at 314, charging station 110 may assess the presence of a fault or fault identifier in the initial health state data 276 as meeting the second condition. The second condition assessed at 314 may include a combination of two or more thresholds applied to two or more of the following: the voltage, current, power, and / or temperature of the battery system 160 or its battery modules, and the thresholds may be combined to consider the presence or absence of a fault indicated by the initial health state data 276.
[0045] In some examples, operations 310, 312, and 314 can be performed by computing system 220 executing a program (e.g., program 271), as described with reference to operation 272. For example, the program executed by computing system 220 can define a first condition and a second condition to be evaluated at 310.
[0046] In process flow 210 at 316, in response to charging request 244, charging station 110 may determine whether to initiate charging of mobile platform 112 based on initial health state data 276. As part of operation 316, charging station 110 may initiate charging of battery system 160 of mobile platform 112 at 318 in response to a first condition being met at 312 and in response to charging request 244. For example, at 319, charging station 110 may establish a charging connection with mobile platform 112 after charging is initiated or as part of initiating charging at 318. As an example, a charging connection with mobile platform 112 may be established by charging station 110 controlling charging interface 140 to connect the electrical conductors of charging cable 146 to electrical system 130. In some examples, by assessing the initial health state of mobile platform 112 before establishing a charging connection, unsatisfactory operation of mobile platform (including unsatisfactory operation of battery system 160) can be limited and not exacerbated by electrical coupling with electrical system 130.
[0047] Furthermore, as part of operation 316, charging station 110 may disable charging of the battery system 160 of mobile platform 112 at 320 in response to the fulfillment of a second condition at 314 (e.g., in the event of a failure of battery system 160). By disabling charging at 320, charging station 110 rejects charging request 244. Since charging has not yet started at 320, disabling charging at 320 may include charging station 110 suppressing the supply of power to mobile platform 112. In some examples, disabling charging of battery system 160 before charging station 110 supplies power to mobile platform 112 can limit unsatisfactory operation of the mobile platform and its battery system without exacerbating problems that might otherwise arise due to the supply of power.
[0048] In at least some examples, in response to the fulfillment of the second condition, charging station 110 may perform one or more additional remedial actions at 322. For example, remedial actions performed at 322 may include charging station 110 alerting emergency services at 324 by sending a message to emergency services infrastructure 118 via communication network 114 through wireless interface 150 or wired interface 152. Additionally or alternatively, remedial actions performed at 322 may include charging station 110 alerting maintenance services at 326 by sending a message to maintenance services infrastructure 120 via communication network 114 through wireless interface 150 or wired interface 152. Additionally or alternatively, remedial actions performed at 322 may include charging station 110 activating fire suppression at 328 by sending a control message to fire suppression system 124 via communication network 114 through wireless interface 150 or wired interface 152.
[0049] When charging is enabled at 318, charging station 110 can perform charging of the battery system 160 of mobile platform 112 at 330 as part of charging operation 331. For example, charging station 110 can supply power to mobile platform 112 at 332. Figure 1 The electrical energy 144 is used to charge the battery system 160 as part of the charging operation 331 performed in 330. Figure 1 In the example, electrical energy 144 can be supplied from charging station 110 to mobile platform 112 via charging interface 140, charging cable 146, and charging interface 162.
[0050] Furthermore, as part of the charging process performed at 330, charging station 110 can monitor the state of charge (SOC) of battery system 160 of mobile platform 112 at 324. At 336 of process flow 212, mobile platform 112 can obtain SOC data 338 indicating the SOC of battery system 160 via wireless communication link 180 and report the SOC data 338 to charging station 110. As a first example, mobile platform 112 can periodically send SOC data 338 to charging station 110 via wireless communication link as part of reporting the SOC at 336. As a second example, as part of the monitoring performed at 334, charging station 110 can periodically request SOC data 338 from mobile platform 112 via wireless communication link, and mobile platform can send SOC data to charging station via wireless communication link in response to each request. As a third example, the mobile platform 112 may report state of charge data 338 to the charging station 110 via a wireless communication link in response to the battery system 160 reaching conditions such as full charge or threshold charge, which may be received by the charging station 110 as part of monitoring performed in 334.
[0051] At 340, charging station 110 can determine whether charging of battery system 160 is complete based on state-of-charge data 338 reported by mobile platform 112. If charging is not complete ( Figure 3 If the answer is "No" in step 334, then the state of charge monitoring can continue, and at step 332, the charging station 110 can continue to supply power to the mobile platform 332 to charge the battery system 160. If charging is complete ( Figure 3 If the "Yes" is selected in process flow 210, charging station 110 can disable charging of mobile platform 112 at 342. At 346 of process flow 210, charging station 110 can initiate the disconnection of electrical coupling with mobile platform 112. For example, charging interface 140 of charging station 110 can be controlled to disconnect the electrical conductors of charging cable 146 from electrical system 130. At 348 of process flow 210, charging station 110 can return to... Figure 2 Operation 240 transitions to an idle state.
[0052] Furthermore, as part of the charging of the mobile platform 112 performed at 330, the charging station 110 can monitor the operational health status of the mobile platform at 344 during the charging process. Figure 4 This includes aspects of method 200 related to the monitoring of the operational health status of the mobile platform 112 during charging by the charging station 110 (as part of operation 344).
[0053] As previously described, the program 271 executed by the computing system 220 of charging station 110 at 272 can be used by the charging station to request, receive, and interpret health status data reported by mobile platform 112. For example, at 410 of process flow 210, during charging at 330, charging station 110 can request and receive operational health status data 412 from mobile platform 112 via wireless communication link 180. Operational health status data 412 can be formatted according to reporting protocol 268.
[0054] Operational health status data 412 can indicate the operating conditions of the battery system 160 of the mobile platform 112. For example, the operating conditions of the battery system 160 may include one or more of the following: the voltage, current, power, and / or temperature of the battery system or its battery modules. (Reference) Figures 5-8 Examples of operating conditions that the mobile platform 112 can measure and report are described in more detail. As another example, operating health status data 412 can indicate a fault in the battery system 160 detected by the mobile platform 112 (e.g., through operating health status data including a fault identifier).
[0055] In this example, operational health status data 412 is provided by mobile platform 112 as part of the operational health status reporting process at 414 of process flow 212. For example, as part of the operational health status report at 414, mobile platform 112 at 416 may obtain operational health status data 412 at least in part based on measurements from the battery system 160 of onboard sensors, and may report the operational health status data to charging station 110 via wireless communication link 180.
[0056] As a first example, mobile platform 112 may periodically send operational health status data 412 to charging station 110 via a wireless communication link as part of operational health status report 414. Charging station 110 may receive and interpret the operational health status data 412 sent by mobile platform 112 via the wireless communication link at 410. As a second example, as part of monitoring performed at 344, charging station 110 may periodically request operational health status data 412 from mobile platform 112 via a wireless communication link during charging, and mobile platform may send operational health status data to charging station via the wireless communication link in response to each request. Charging station 110 may receive and interpret the operational health status data 412 sent by mobile platform 112 in response to the request as part of monitoring performed at 344. As a third example, mobile platform 112 may report operational health status data 412 in response to detecting that a condition is met during charging, which may be received by charging station 110 via the wireless communication link at 410.
[0057] At 418 of process flow 210, charging station 110 may evaluate operational health status data 412 received from mobile platform 112. As part of evaluating operational health status data 412 at 418, charging station 110 may determine at 420 whether the operational health status data meets a first condition indicating satisfactory operation of battery system 160 of mobile platform 112 during charging. The first condition evaluated by charging station 110 at 420 during charging may be the same as or different from the first condition evaluated by charging station 110 at 312 prior to charging mobile platform 112. For example, computing system 220 of charging station 110 may compare operational health status data 412 with one or more thresholds to determine at 420 whether the first condition is met. In this example, the values of voltage, current, power, and / or temperature of battery system 160 or battery modules of battery system (module-specific operating conditions) identified by operational health status data 412 may be compared with one or more thresholds defined by program 271 or other programs executed by computing system 220 within program 230. Additionally or alternatively, at 420, charging station 110 may assess the absence of a fault or fault identifier in operational health status data 412 as meeting a first condition. The first condition assessed at 420 may include a combination of two or more thresholds applied to two or more of the following: voltage, current, power, and / or temperature of battery system 160 or battery modules of the battery system, and the assessment of the thresholds may be combined to consider the presence or absence of a fault indicated by operational health status data 412.
[0058] Additionally or alternatively, as part of evaluating the operational health status data 412 at 418, charging station 110 may determine at 422 whether the operational health status data meets a second condition indicating unsatisfactory operation (e.g., malfunction) of the battery system 160 of mobile platform 112 during charging. The second condition evaluated by charging station 110 at 422 during charging may be the same as or different from the second condition evaluated by charging station at 314 prior to charging mobile platform 112.
[0059] For example, the computing system 220 of charging station 110 can compare the operational health status data 412 with one or more thresholds to determine at 422 whether a second condition is met. In this example, the values of voltage, current, power, and / or temperature of the battery system 160 or its battery modules (module-specific operating conditions) identified by the operational health status data 412 can be compared with one or more thresholds defined by program 271 or other programs executed by computing system 220 within program 230. Additionally or alternatively, at 422, charging station 110 can assess the presence of a fault or fault identifier in the operational health status data 412 as meeting the second condition. The second condition assessed at 422 may include a combination of two or more thresholds applied to two or more of the following: the voltage, current, power, and / or temperature of the battery system 160 or its battery modules, and the thresholds may be combined to consider the presence or absence of a fault indicated by the operational health status data 412.
[0060] In some examples, operations 418, 420, and 422 can be performed by executing program 271 through the computing system 220 of charging station 110, as described with reference to operation 272. For example, program 271 can define a first condition and a second condition evaluated in 418.
[0061] In process flow 210 at 424, charging station 110 determines whether to continue charging mobile platform 112 based on operational health status data 412. As part of operation 424, charging station 110 may, at 426, allow charging of mobile platform 112's battery system 160 to continue in response to a first condition being met at 420. Furthermore, as part of operation 424, charging station 110 may, at 428, disable charging of mobile platform 112's battery system 160 in response to a second condition being met at 422, thereby stopping charging of the mobile platform.
[0062] In some examples, in response to the second condition being met at 422, charging station 110 may perform one or more additional remedial operations at 430. For example, the remedial operation performed at 430 may include charging station 110 initiating a disconnection of its electrical coupling with mobile platform 112 at 432. For example, charging interface 140 of charging station 110 may be controlled to disconnect the electrical conductors of charging cable 146 from electrical system 130. After disconnection at 432, charging station 110 may transition to an idle state, as previously described in [previous examples]. Figure 3As described in 348. Additionally or alternatively, remedial operations performed at 430 may include the charging station 110 alerting emergency services at 434 by sending a message to emergency service infrastructure 118 via communication network 114 through wireless interface 150 or wired interface 152. Additionally or alternatively, remedial operations performed at 430 may include the charging station 110 alerting maintenance services at 436 by sending a message to maintenance service infrastructure 120 via communication network 114 through wireless interface 150 or wired interface 152. Additionally or alternatively, remedial operations performed at 430 may include the charging station 110 activating fire suppression at 438 by sending a control message to fire suppression system 124 via communication network 114 through wireless interface 150 or wired interface 152.
[0063] Charging station 110 can perform operations 410, 418, and 424 continuously or periodically, as... Figure 4 Part of the circuit 440 schematically depicted in the diagram. For example, as Figure 3 As part of operation 330, charging station 110 can monitor the operating status during charging at 344, and at the same time monitor the state of charge at 334.

The battery management system 500 is... Figure 1 An example of the battery management system 164 of the mobile platform 112. Figure 5 In the example, the battery system 510 includes at least a first battery module 512-1 and a second battery module 512-2. The battery system 510 may also include one or more additional battery modules, which... Figure 5 Described as battery module 512-N, where "N" can be any suitable number of battery modules. Battery system 510 is... Figure 1 An example of the battery system 160 of the mobile platform 112. It should be understood that the battery system 160 and battery management system 164 of the mobile platform 112 may have the same characteristics as those in the reference... Figure 5 The examples described have different configurations.
[0065] Each battery module of the battery system 510 includes a set of battery cells 514, which includes one or more battery cells, an example of which is depicted as battery cell 516. In at least some examples, each battery module may include any suitable number of multiple battery cells (e.g., including dozens, hundreds or more battery cells).
[0066] Multiple battery modules of the battery system 510 can be arranged relative to the electrical load 530 in series, parallel, or a combination of series and parallel configurations. Figure 5In the depicted example, battery modules 512-1 and 512-2 through 512-N are arranged in series to form battery pack 518-1. Battery system 510 may include multiple battery packs arranged in parallel with respect to electrical load 530, wherein each battery pack includes one or more battery modules. For example, in Figure 5 The diagram depicts battery packs 518-2 to 518-M, where "M" can be any suitable number of battery packs. In another example, battery modules 512-2 to 512-N can be included in different battery packs arranged in parallel with battery pack 518-1, which includes at least battery module 512-2. For example, battery module 512-2 can form part of battery pack 518-2, and battery pack 512-N can form part of battery pack 518-M. Therefore, it should be understood that the multiple battery modules of battery system 510 can include any suitable arrangement of battery modules relative to electrical load 530.
[0067] The battery management system 500 includes a controller device 520 and a plurality of module interface devices 522-1 to 522-N, which are operatively coupled to the controller device via electrical connections 524-1 to 524-N, respectively. For example, the controller device 520 may form Figure 2 It is part of the computing system 222.
[0068] For each of the multiple battery modules in the battery system 510, a corresponding module interface device among the multiple module interface devices 522-1 to 512-N of the battery management system 500 is operatively coupled to or configured to be operatively coupled to the anode and cathode terminals of that battery module, as referenced. Figure 6 This is described in further detail. Therefore, the battery management system 500 may include a module interface device for each battery module of the battery system 510. Figure 5 In the example, the battery management system 500 includes a first module interface device 522-1 operably coupled to the anode and cathode terminals of battery module 512-1, and a second module interface device 522-2 operably coupled to the anode and cathode terminals of battery module 512-2. For each additional battery module of the battery system 510 represented by battery modules 512-N, the battery management system 510 includes an additional module interface device represented by module interface devices 522-N.
[0069] For reference Figure 6In further detail, each module interface device 522-1 to 522-N of the battery management system 500 includes measurement circuitry and switching circuitry. The measurement circuitry of each module interface device can be used by the controller device 520 to independently measure one or more operating conditions of the battery module operatively coupled to that module interface device. The operating conditions of the battery module are referred to herein as module-specific operating conditions, which can be measured as module-specific measurement results. Examples of module-specific operating conditions that can be measured by the measurement circuitry of the module interface device include the current between the anode and cathode of the battery module or the voltage across the anode and cathode of the battery module.
[0070] Each module interface device's switching circuit can be used by the controller device 520 to connect and disconnect the battery module relative to the electrical load 530. For example, the controller device 520 can independently disconnect the first battery module 512-1 from the electrical load 530 via the switching circuit of the module interface device 522-1, and can independently connect the first battery module 512-1 to the electrical load 530. The controller device 520 can also independently measure one or more operating conditions of the first battery module 512-1 via the measurement circuit of the module interface device 522-1. As another example, the controller device 520 can independently disconnect the second battery module 512-2 from the electrical load 530 via the switching circuit of the module interface device 522-2, and can also independently connect the second battery module 512-2 to the electrical load 530. The controller device 520 can also independently measure one or more operating conditions of the second battery module 512-2 via the measurement circuit of the module interface device 522-2.
[0071] In at least some examples, the electrical load 530 takes the form of a test electrical load that forms part of the battery management system 500. In these examples, the electrical load 530 as a test load can be used to perform a test process relative to the battery system 510 before interfacing the battery system with another system or device that will be powered by the battery system. In other examples, the electrical load 530 can form part of another system or device that will be powered by the battery system 510 during the operation phase or state of that system or device. The test process described herein can be performed as part of a test phase that is performed before, during, or after the operation phase or state of the system or device utilizing the battery system 510 as an electrical energy source.
[0072] The battery management system 500 may also include a load measurement circuit 532 and a relay device 534, which can be used by the controller device 520 to measure operating conditions of the electrical load 530 across the power delivery circuit 536. These operating conditions are referred to herein as load-specific operating conditions and can be measured as load-specific measurements. For example, one or more load-specific operating conditions may include the voltage and / or current between the high and low sides of the electrical load.
[0073] Figure 5 The schematically depicted power delivery circuit 536 includes various electrical paths that operatively couple an electrical load 530 to a plurality of module interface devices 522-1 to 522-N for delivering or transmitting power, which in turn are operatively coupled to a plurality of battery modules 512-1 to 512-N according to any suitable series and / or parallel configuration. The power delivery circuit 536 can be electrically coupled to... Figure 1 The charging interface 162 is used to distribute electrical energy 144 to the battery modules of the battery system 510 via a corresponding module interface device. The relay device 534 can be used by the controller device 520 in conjunction with the load measurement circuit 532 to measure operating conditions across the electrical load 530 (e.g., by controlling the relay device 534 to connect or disconnect the load measurement circuit 532 to the power delivery circuits 536 on the high and low sides of the electrical load 530). Figure 5 In this configuration, electrical pathways 542 and 544 operatively couple the controller device 520 to the load measurement circuit 532 and the relay device 534, respectively.

However, in at least some examples, the battery module may have different numbers and / or performance ratings (e.g., voltage and / or current) of battery cells in some or all of the battery modules 512-1 and 512-2 to 512-N.
