It should be understood, however, that the following descriptions, while indicating at least one embodiment and numerous specific details thereof, are given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the embodiments herein without departing from the spirit thereof, and the embodiments herein include all such modifications.SUMMARY
[0018] Embodiments herein disclose systems for thermal management of electrical energy storage devices placed within a dock of a charging and interchange station. The charging and interchange station may include one or more racks having one or more docks, wherein each dock is configured to house at least one electrical energy storage device. Each rack may include a Rack Supervising Unit (RSU) configured to monitor and control the thermal management system.
[0019] The system includes a fluid conduit for facilitating coolant flow throughout the thermal management system. A primary degassing and collection tank is configured to remove gas from the coolant, collect the gas, and replenish the coolant for circulation. A primary pump draws coolant from the primary degassing and collection tank, pressurizes the drawn coolant, and moves the pressurized coolant through the fluid conduit. A heat exchanger receives the pressurized coolant from the primary degassing and collection pump. The heat exchanger is configured to maintain the coolant temperature under ideal conditions. A secondary degassing and collection tank receives the coolant from the heat exchanger for further degassing and collection. A dock pump pressurizes the coolant received from the secondary degassing and collection tank before the coolant enters the dock. An inlet temperature sensor is positioned at the inlet of the secondary degassing and collection tank to monitor the coolant’s temperature as it enters the secondary degassing and collection tank. An outlet temperature sensor is installed at the outlet of the dock to measure the temperature of the coolant leaving the dock. Each dock features a coolant connector designed to interface with the electrical energy storage device’s coolant connector, enabling coolant circulation. The station may include one or more dock pumps configured to serve one or more docks.
[0020] The RSU is configured to monitor the charging status of the electrical energy storage device located in the dock, verify and confirm the charging status, monitor the inlet coolant temperature using the inlet temperature sensor, and compare the inlet coolant temperature to a first pre-defined temperature value. If the inlet temperature exceeds the firstpre-defined temperature value, the RSU alerts an operator and halts the charging of the dock. The RSU also monitors the outlet coolant temperature, compares the inlet and outlet temperatures, and determines if the difference between the inlet and outlet coolant temperatures exceeds a second pre-defined temperature value. If the difference between the inlet and outlet coolant temperatures exceeds the second pre-defined temperature value, the RSU halts the charging process and notifies the operator of a fault. Additionally, the RSU suspends the charging process, on determining that the electrical energy storage device is in an overheated state.
[0021] The RSU is also configured to perform charging, thermal management, and maintenance functions for the electrical energy storage devices, and to collect data from various sources including the electrical energy storage device.
[0022] The RSU is further configured to utilize a communication network for transferring data in real time to and from the electrical energy storage device, where the network may be a Control Area Network (CAN) or a Local Interconnect Network (LIN). The RSU collects data from various sources including the storage device and performs charging, thermal management, and maintenance functions.
[0023] Embodiments herein disclose methods for thermal management of electrical energy storage devices in a charging and interchange station. The method includes monitoring, by the RSU, the charging status of an electrical energy storage device located in a dock, verifying and confirming the charging status of the electrical energy storage device, monitoring the inlet coolant temperature using the inlet temperature sensor at the secondary tank inlet, and comparing the inlet temperature to a first pre-defined value. The RSU also monitors the outlet coolant temperature at the dock outlet, compares the inlet and outlet temperatures, and determines if the difference between the inlet and outlet temperatures exceeds a second predefined value. Based on the monitored temperatures, the RSU manages the thermal condition of the electrical energy storage device. The RSU may alert the operator and halt the charging process if the inlet temperature exceeds the first pre-defined value. Similarly, it notifies the operator of a fault and halts charging if the temperature difference exceeds the second predefined value, or if overheating is detected.
[0024] The method further includes circulating coolant through a fluid conduit to various components of the thermal management system. The primary pump draws and pressurizes coolant from the primary tank, which is then sent to the heat exchanger. The coolantflows from the heat exchanger to the secondary tank for degassing and collection, then pressurized by the dock pump before entering the dock.BRIEF DESCRIPTION OF FIGURES

[0034] The embodiments herein achieve systems and methods for performing thermal management of electrical energy storage devices. Referring now to the drawings, and more particularly to FIGS. 1 through 2, where similar reference characters denote corresponding features consistently throughout the figures, there are shown embodiments.
[0035] The following terms and reference numerals have been referred to herein:100 - System for the thermal management of electrical energy storage devices102 - Electrical energy storage device (EESD)105 - Dock110 - Fluid conduit115 - Primary degassing and collection tank120 - Primary pump125 - Heat exchanger130 - Secondary degassing and collection tank135 - Secondary pump140 - Inlet sensor145 - Outlet sensor
[0036] FIG. 1 illustrates a system for performing thermal management of electrical energy storage devices in a charging and interchange station. The system 100 includes one or more electrical energy storage devices 102, wherein each electrical energy storage device 102 can be housed in a dock 105 situated in a rack containing one or more docks at the charging and interchange station. Each dock 105 features a coolant connector and an electrical connectordesigned to interface with the electrical energy storage device's coolant connector and electrical connector respectively, enabling coolant circulation and power supply. A fluid conduit 110 facilitates coolant flow to various components throughout the thermal management system 100.
[0037] The thermal management system 100 includes a primary degassing and collection tank 115. The primary degassing and collection tank 115 removes formed and accumulated gas from the coolant, collects the gas, and replenishes the coolant for circulation. The primary degassing and collection tank 115 maintains the efficiency of the cooling system by ensuring that the coolant remains free from gas bubbles that could impede its performance. The primary degassing and collection tank 115 can be designed with various configurations (for example, a vertical or horizontal orientation), depending on the spatial constraints of the charging and interchange station.
[0038] A primary pump 120 draws coolant from the primary degassing and collection tank 115, pressurizes the drawn coolant, and moves the pressurized coolant through the fluid conduit 110. A heat exchanger 125 receives the pressurized coolant from the primary pump 120. The heat exchanger 125 is utilized to maintain the coolant temperature under ideal conditions.
[0039] In an embodiment, the primary pump 120 can be of various types, such as, but not limited to, a centrifugal pump, a positive displacement pump, an axial flow pump, and so on, depending on the specific requirements of the system. The selection of the pump type and capacity can be based on one or more factors (such as, but not limited to, the volume of coolant to be circulated, the pressure requirements of the system, the overall efficiency of the thermal management process, and so on).
[0040] In another embodiment herein, various types of heat exchangers can be employed (such as, but not limited to, plate heat exchangers, shell and tube heat exchangers, fin and tube heat exchangers, and so on) depending on the specific cooling requirements and space constraints of the system. The heat exchanger 125 can work with different cooling mediums, (such as air) or a liquid coolant, to effectively dissipate heat from the primary coolant.
[0041] The thermal management system 100 includes the secondary degassing and collection tank 130, wherein the secondary degassing and collection tank 130 can receive the coolant from the heat exchanger 125 for further degassing and collection. The additional degassing stage ensures that any remaining gas bubbles or impurities that are formed oraccumulated are removed from the coolant before it is circulated to the docks. In an embodiment herein, the secondary degassing and collection tank 130 can comprise at least one or more baffles and / or one or more vortex breakers to enhance the separation of gas from the liquid coolant.
[0042] Each dock 105 can be equipped with a dock pump 135, wherein the dock pump 135 can pressurize the coolant received from the secondary degassing and collection tank 130, before the coolant enters the dock 105. The dock pump 135 ensures that the coolant is delivered to each electrical energy storage device at the appropriate pressure for optimal cooling performance. In an embodiment herein, a single dock pump can be shared by a plurality of docks, depending on operational needs. This configuration can help reduce the overall number of components in the system, potentially lowering costs and simplifying maintenance. In an embodiment herein, a single dock pump can serve one dock.
[0043] An inlet temperature sensor 140 is positioned at the inlet of the secondary degassing and collection tank 130. The inlet temperature sensor 140 monitors the coolant's temperature as the coolant enters the secondary degassing and collection tank 130. The inlet temperature sensor 140 provides real-time data on the coolant temperature, allowing for precise control of the cooling process. The temperature sensors can be one of, but not limited to, thermocouples, resistance temperature detectors (RTDs), or thermistors, depending on the required accuracy and response time.
[0044] Additionally, an outlet temperature sensor 145 is installed at the outlet of each dock 105. The outlet temperature sensor 145 measures the temperature of the coolant leaving the respective dock 105. The outlet temperature sensor 145 provides valuable information about the heat transfer occurring within each electrical energy storage device, allowing for individual monitoring and control of the cooling process for each unit. The data from the outlet temperature sensor 145 can be used to optimize the cooling strategy, detect potential issues with specific electrical energy storage devices, and ensure efficient operation of the entire thermal management system.
[0045] The thermal management system 100 operates by circulating coolant through a closed loop. The coolant is initially drawn from the primary degassing and collection tank 115 by the primary pump 120. The pressurized coolant then flows through the heat exchanger 125, where its temperature is regulated to the desired level. In the next step, the coolant enters the secondary degassing and collection tank 130 for further gas removal and collection. The dockpump 135 then pressurizes the coolant before it enters the respective docks 105, where the coolant circulates through the electrical energy storage devices 102 to absorb heat. The heated coolant then returns to the primary degassing and collection tank 115 to begin the cycle anew.
[0046] A Rack Supervising Unit (RSU) (not shown) is provided within each rack to monitor and charge the electrical energy storage units accommodated in the rack. The RSU collects data from various sources (including the electrical energy storage device) and performs functions such as, but not limited to, charging, thermal management, maintenance, and so on.
[0047] FIG. 2 is an example flow chart depicting a method for performing thermal management of electrical energy storage devices in a charging and interchange station. The thermal management method for electrical energy storage devices (EESD) 102 involves several steps to ensure optimal operation and safety. Initially, the RSU utilizes networks (such as but not limited to, a Control Area Network (CAN), a Local Interconnect Network (LIN), and so on) for transferring data in real-time to and from the electrical energy storage device 102. This allows the RSU to continuously monitor the charging status and thermal conditions of each electrical energy storage device 102 located in the respective docks 105.
[0048] The RSU can further perform temperature monitoring and control, to ensure optimal thermal management. Initially, the RSU verifies and confirms the charging status of each electrical energy storage device 102. Once confirmed, the RSU proceeds to monitor the inlet coolant temperature (Ti) using the inlet temperature sensor 140. This temperature is maintained by the heat exchanger 125 and should ideally be kept at or below a first pre-defined temperature value (for example, 8°C, 10°C, 12°C, 15°C, and so on), wherein the first predefined temperature value can depend on the specific requirements of the electrical energy storage devices and the overall system design. An increase in the inlet coolant temperature beyond the first pre-defined temperature value can indicate a potential heat exchanger malfunction. On detecting an increase in the inlet coolant temperature beyond the first predefined temperature value, the RSU can alert the operator and halt the further charging process of the electrical energy storage device present in the dock, thereby preventing potential damage to the electrical energy storage devices. This proactive approach ensures the safety and longevity of the system components.
[0049] If the coolant temperature remains within optimal parameters (i.e., at or below the first pre-defined temperature value), the RSU proceeds to monitor the outlet coolant temperature using the outlet temperature sensor 145. The RSU compares the inlet and outletcoolant temperatures for each dock. If the difference between the inlet and outlet coolant temperatures exceeds a second pre-defined temperature value (for example, 8°C, 10°C, 12°C, 15°C, and so on), this can indicate a potential overheating of the electrical energy storage device in that particular dock. In such cases, the RSU halts the charging process, notifies the operator of the faulty situation to take further action.
[0050] For instance, if the inlet coolant temperature is less than 10°C and the outlet coolant temperature exceeds 12°C, the RSU identifies this as overheating of the electrical energy storage device 102. In such cases, the RSU can notify the operator of the error and suspend the charging process for that specific device until the problem is addressed. This granular level of control allows for efficient management of the entire rack of electrical energy storage devices, ensuring that issues with individual units do not compromise the operation of the entire system.
[0051] The method depicted in FIG. 2 may also include additional steps or decision points not explicitly shown in the flowchart. For example, the RSU may continuously loop through these monitoring and decision-making processes throughout the entire charging cycle of the EESD. It may also incorporate additional safety checks, such as monitoring the pressure in the coolant system, checking for leaks, or assessing the overall health of the EESD based on other parameters.
[0052] Furthermore, the method may include steps for adjusting the cooling system based on the temperature readings. For instance, if the temperature difference is approaching but has not yet exceeded the second pre-defined value, the RSU might increase the coolant flow rate or adjust the heat exchanger settings to prevent potential overheating.
[0053] The thermal management system 100 can be further enhanced with additional features and alternative embodiments. For example, the system could incorporate variable speed pumps for both the primary pump 120 and the dock pumps 135, allowing for dynamic adjustment of coolant flow rates based on the thermal load of each electrical energy storage device. Additionally, the heat exchanger 125 could be designed with multiple stages or as a modular system, allowing for easy scaling of cooling capacity as the number of electrical energy storage devices in the charging and interchange station increases.
[0054] Furthermore, the RSU could be equipped with machine learning methodologies to predict potential thermal issues based on historical data and current operating conditions. This predictive capability could allow for pre-emptive actions to be taken before criticaltemperature thresholds are reached, further enhancing the reliability and efficiency of the thermal management system.
[0055] The embodiments disclosed herein can be implemented through at least one software program running on at least one hardware device and performing network management functions to control the network elements. The elements include blocks which can be at least one of a hardware device or a combination of hardware devices and software modules.
[0056] The embodiments disclosed herein describe systems and methods for performing thermal management of electrical energy storage devices. Therefore, it is understood that the scope of the protection is extended to such a program and in addition to a computer readable means having a message therein, such computer readable storage means contain program code means for implementation of one or more steps of the method, when the program runs on a server or mobile device or any suitable programmable device.
