Description

Field The present disclosure pertains to the field of mobile power supply systems, for example systems which involve rechargeable battery cells and power conversion devices. Exemplary applications of such a system are in areas such as electric vehicle (EV) charging and providing remote power supply, e.g. off-grid. Background The advent of electric vehicles (EVs) has necessitated the development of efficient charging solutions. Among these, fast chargers, which deliver direct currents, have emerged as a popular choice due to their ability to deliver a significant amount of charge in a relatively short period. However, the deployment of these fast chargers presents several challenges. One of the primary issues is the difficulty in installation. Fast chargers require landowner permission for installation, which often results in delays in the deployment of these charging stations. Additionally, the installation process involves significant construction work, including electrical infrastructure upgrades and groundworks for physical installation. This not only increases the cost, but also the time required to set up these charging stations. Another significant problem with fast chargers is their fixed location. Once installed, these chargers cannot readily be moved. This poses a challenge for EVs that run out of charge and are not within reach of a fixed charging station. Mobile charging units exist which can be utilized with a conventional mains power supply, e.g. 120V or 240V, but they are of much lower power output (up to 7kW only) and deliver alternating rather than direct currents, and thus are slower and less efficient than fixed, purpose-built fast chargers. As a result, EVs relying on mobile chargers experience longer charging times, which reduces the practicality of these mobile solutions. In summary, while fast chargers and mobile charging units have their respective advantages, they also come with significant drawbacks. The challenges associated with the installation and fixed location of fast chargers, coupled with the slower charging speeds of mobile units, present obstacles for efficient EV charging, or indeed the supply of high power flexibly at desired locations.

The battery cell management system ensures that the battery cell operates within safe and efficient parameters, thereby prolonging the life of the battery cell and improving the overall performance of the mobile power supply 100. The battery cell management system interacts with other components of the mobile power supply 100, such as the high-power subsystems, to control the receipt and delivery of electrical energy. 1.1.5. Integrated CCS control system The integrated CCS control system 280 is a component of the mobile power supply 100. In some implementations, it is configured to manage the receipt and delivery of direct current under CCS protocols. The integrated CCS control system 280 is a sophisticated control mechanism that ensures the efficient and safe operation of the mobile power supply 100. It controls the receipt of the first direct current 160 from the DC input with the first CCS protocol and controls the delivery of the second direct current 170 to the DC output with the second CCS protocol. This dual control mechanism allows the mobile power supply 100 to manage both the charging and discharging processes efficiently.

In particular, the integrated CCS control system 280 is configured to receive an indication (e.g. via one or more power demand request messages) of a desired current and / or voltage from the re-chargeable battery cell 110. In response, the integrated CCS control system 280 is configured to transmit the desired current and / or voltage to the source of the current being received on the CCS input connector 140 and accordingly cause the desired current and / or voltage to be generated and transmitted by the source of the current being received on the CCS input connector 140. Similarly, the integrated CCS control system 280 is configured to receive (e.g. via one or more power demand request messages) an indication of a desired current and / or voltage from a device that is receiving the second direct current 170. In response, the integrated CCS control system 280 is configured to control the power output and accordingly control the generation and output of the second direct current 170 in accordance with the received desired current and / or voltage. Based on this, it can be further seen that the integrated CCS control system 280 is configured to control the receipt of the first direct current 160 with the first CCS protocol and control the delivery of the second direct current 170 with the second CCS protocol simultaneously. In other words, the integrated CCS control system 280 can be configured to enable simultaneously charging and discharging of the mobile power supply 100.

The low-power subsystem 290 provides the required power to the integrated CCS control system 280, enabling it to perform its control functions effectively. In practice, the low-power subsystem 290 could adjust its power output based on the requirements of the integrated CCS control system 280, ensuring that it always has the power it needs to function effectively. Furthermore, the low-power subsystem 290 can be powered by a battery, such as the rechargeable battery cell 110. In that scenario, the low-power subsystem 290 is configured to provide a plurality of different power modes. As the low-power subsystem 290 switches between the power modes, non-essential components of the low-power subsystem 290 are selectively turned off. The low-power subsystem 290 is configured to include at least one power mode in which only the critical control and safety functions of the low-power subsystem 290 are maintained. When the battery that powers the low-power subsystem 290 enters a particular charge state, such as a low charge state, the low-power subsystem 290 is configured to automatically enter a particular power mode, such as the power mode in which only the critical control and safety functions of the low-power subsystem 290 are maintained. This automatic switching between power modes to selectively turn off non-essential components of the low-power subsystem 290 maximises battery life and enhances safety. The low-power subsystem 290 can be separate from the first high-power subsystem 120 and the second high-power subsystem 130, which is advantageous because it reduces the likelihood of interference between the high and low power parts of the mobile power supply 100. 1.1.7. Safety features The mobile power supply 100 includes several safety features to ensure its safe operation. These safety features include a safety monitoring system, a bulkhead, and a circuit breaker. The safety features are adapted to monitor the operation of the mobile power supply 100, prevent accidents, and protect the system and its users from potential harm. In practice, the safety features could detect a potential problem, such as an overload or a short circuit, and allow immediate action to be taken to prevent damage or injury. In addition, the CCS output connector 150 may be configured to deliver the second direct current 170 to an electrical cable removably connected to the CCS output connector 150. In some such configurations, the electrical cable is configured to be connected to or disconnected from the CCS output connector 150 by a service engineer and cannot be connected to or disconnected from the CCS output connector 150 by an end user. Alternatively, the electrical cable can be connected to the CCS output connector 150 using a safety block. Prior to and / or during delivery of the second direct current 170, the mobile power supply 100 is configured to determine whether the safety block is in place. If the safety block is not in place, the mobile power supply 100 is configured to prevent delivery of the second direct current 170. Alternatively or additionally, in implementations in which the first high-power subsystem 120 includes one or more contactors configured to perform switching, the first high-power subsystem 120 may also include one or more redundant contactors to ensure that the first high-power subsystem 120 maintains its ability to switch even if one of its contactors fails. Similarly, in implementations in which the second high-power subsystem 130 includes one or more contactors configured to perform switching, the second high-power subsystem 130 can also include one or more redundant contactors to ensure that the second high-power subsystem 130 maintains its ability to switch even if one of its contactors fails. 1.1.7.1. Safety monitoring system The safety monitoring system is one of the safety features of the mobile power supply 100. In some examples, it is configured to monitor the operation of the mobile power supply 100 and take action when needed to ensure safety. The safety monitoring system could include various sensors and control mechanisms that monitor the operation of the mobile power supply 100 and detect potential problems. When a potential problem is detected, the safety monitoring system could take immediate action, such as shutting down the system or triggering an alarm. In practice, the safety monitoring system could detect a potential malfunction and take immediate action to prevent damage or injury. 1.1.7.2. Bulkhead The bulkhead is a safety feature of the mobile power supply 100. The bulkhead is adapted to separate the rechargeable battery cell 110 from the first high-power subsystem 120 and second high-power subsystem 130. The bulkhead is a physical barrier that isolates the high-power delivery and receipt systems from the rest of the device, providing an additional layer of safety by way of physical separation. This reduces the likelihood of short circuits as well as providing thermal isolation of the first high-power subsystem 120 and the second high-power subsystem 130 from the rest of the device. In practice, the bulkhead could prevent a potential problem in one part of the system from affecting other parts of the system, thereby enhancing the overall safety of the mobile power supply 100. 1.1.7.3. Circuit breaker The circuit breaker is one of the safety features of the mobile power supply 100. In some examples, it is adapted to interrupt the supply of the second direct current 170 when broken. The circuit breaker is a safety device that protects the system and its users from potential harm by allowing the output of the mobile power supply 100 to be immediately shut off. In some implementations, the circuit breaker is configured such that once the supply of the second direct current 170 has been interrupted by the circuit breaker, the circuit breaker must be manually reset before it will allow the supply of the second direct current 170 to resume. 1.2. Modular battery network The mobile power supply 100 can be part of a modular battery network 180. In some configurations, the modular battery network 180 is adapted to connect additional rechargeable battery cells 110 to the mobile power supply 100. The modular battery network 180 provides a flexible and scalable solution for increasing the energy storage capacity of the mobile power supply 100. It allows additional rechargeable battery cells 110 to be connected to the mobile power supply 100, increasing its energy storage capacity and extending its operational time. In practice, the modular battery network 180 could be used to connect up to five additional rechargeable battery cells 110 to the mobile power supply 100, depending on the energy storage requirements of the application. When one or more additional rechargeable battery cells 110 are connected to the mobile power supply 100, the first high-power subsystem 120 is used to charge all of the rechargeable battery cells 110 and the second high-power subsystem 130 is used to deliver power from all of the rechargeable battery cells 110. The additional rechargeable battery cells 110 can include direct connections to each other and to the rechargeable battery cell 110 of the mobile power supply 100 to enable communication across the modular battery network 180. The modular battery network 180 can be referred to as a battery extension system (BES). 1.3. Modular mobile power supply The modular mobile power supply is a combination of two or more mobile power supplies 100. The modular mobile power supply provides a scalable solution for delivering electrical energy. It allows multiple mobile power supplies 100 to be combined, increasing the overall energy storage and delivery capacity of the system. The modular mobile power supply is flexible and adaptable, capable of meeting the energy requirements of a wide range of applications. In practice, since it is formed of several mobile power supplies 100, the modular mobile power supply could be used to deliver a large amount of electrical energy, making it suitable for high-power applications and / or high-capacity applications. 1.4. First Mobile Power Supply Conversion Device The first mobile power supply conversion device 190 is a component of the mobile power supply 100. In some implementations, it is adapted to receive a first alternating current from a three-phase power supply and convert it to a first direct current 160. In some implementations, the first alternating current is 63A and the first direct current provides a power of at least 40kW. In some implementations, the first alternating current is 100A and the first direct current provides a power of at least 45kW, 50kW, 55kW, 60kW, or 65kW. In some such implementations, the first mobile power supply conversion device 190 is configured to set the maximum power level of the first direct current. The first mobile power supply conversion device 190 then delivers the first direct current 160 to the DC input of the CCS input connector 140 under the control of the first CCS protocol. This conversion process allows the mobile power supply 100 to receive power from a three-phase power supply, which is a common type of power supply in many industrial and commercial settings. The first mobile power supply conversion device 190 is adapted to deliver high power, making it capable of charging the mobile power supply 100 fast. In practice, the first mobile power supply conversion device 190 could receive a first alternating current from a three-phase power supply, convert it to a first direct current 160, and deliver the first direct current 160 to the DC input of the CCS input connector 140, thereby charging the rechargeable battery cell 110 of the mobile power supply 100. In some configurations, the first mobile power supply conversion device 190 is configured to perform metering, meaning that it measures the amount of energy that it has delivered. In some configurations, multiple first mobile power supplies 190 are connected to the same three-phase power supply 200. In some such configurations, each first mobile power supply conversion device 190 is configured to perform dynamic load management to manage the use of the output of the three-phase power supply 200. In some configurations, the first mobile power supply conversion device 190 has an ingress protection rating of IP54. In some configurations, the first mobile power supply conversion device 190 includes an isolator switch. The isolator switch functions as a safety feature that, when activated, is configured to prevent input power (e.g. the first alternating current 210) from crossing the isolator switch, therefore preventing it from being delivered to the first mobile power supply conversion device 190. 1.5. Second Mobile Power Supply Conversion Device The second mobile power supply conversion device 240 is another component of the mobile power supply 100. In some configurations, it is adapted to receive a second alternating current 230 from an electricity grid and convert it to a third direct current 250. The second mobile power supply conversion device 240 then delivers the third direct current 250 to the rechargeable battery cell 110 of the mobile power supply 100. This conversion process allows the mobile power supply 100 to receive power from an electricity grid, which is a common source of power in many residential and commercial settings. The second mobile power supply conversion device 240 is adapted to handle high-power inputs, making it suitable for applications that require a large amount of electrical energy. In practice, the second mobile power supply conversion device 240 could receive a second alternating current 230 from an electricity grid, convert it to a third direct current 250, and deliver the third direct current 250 to the rechargeable battery cell 110, thereby charging the battery cell directly from an electricity grid. 2. Operation Operation of the mobile power supply 100 involves several steps that enable efficient receipt, storage, and delivery of electrical energy. These steps are controlled by various components of the mobile power supply 100, including the first high-power subsystem 120 and the second high-power subsystem 130, the rechargeable battery cell 110, and the integrated CCS control system 280. The process includes the control of receipt and delivery of DC power under the CCS protocol, the battery charging and discharging process, and the operation of the modular battery network 180. These steps ensure the efficient and safe operation of the mobile power supply 100, making it suitable for a wide range of applications. 2.1. Control of Direct Current Receipt and Delivery under CCS protocol The control of direct current receipt and delivery under respective CCS protocols is part of the operation of the mobile power supply 100. Specifically, the receipt of the first direct current 160 from the DC input is controlled with a first CCS protocol and the delivery of the second direct current 170 to the DC output is controlled with a second CCS protocol. This dual control mechanism allows the mobile power supply 100 to manage both the charging and discharging processes efficiently, also at the same time. The first CCS protocol entails communication between a source of the first direct current 160 (which in some examples is the mobile power supply conversion device 190) and the mobile power supply 100. This communication enables an authentication process to be performed, and also allows the receipt of the first direct current 160 to be governed by one or more charging parameters, which could, for example, be based on the present charge level of the rechargeable battery cell 110. Similarly, the second CCS protocol entails communication between the mobile power supply 100 and the recipient of the second direct current 170 (which, in some examples, is an EV). This communication enables an authentication process to be performed, and also allows the delivery of the second direct current 170 to be governed by one or more charging parameters, which could, for example, be based on the present charge level of the EV. More generally, the CCS protocols can involve monitoring the power levels and adjusting the flow of current accordingly to ensure optimal performance of the mobile power supply 100. This process can be performed by the integrated CCS control system 280. 2.2. Battery Charging and Discharging Process The battery charging and discharging process is another step in the operation of the mobile power supply 100. During the charging process, the first high-power subsystem 120 delivers the first direct current 160 to the rechargeable battery cell 110. During the discharging process, the second high-power subsystem 130 converts an output of the rechargeable battery cell 110 to a second direct current 170. 2.3. Modular Battery Network Operation The mobile power supply 100 can be part of a modular battery network 180 which connects one or more additional rechargeable battery cells 110 to the mobile power supply 100, increasing its energy storage capacity and extending its operational time. The modular battery network 180 uses the first high-power subsystem 120 and second high-power subsystem 130 to receive and deliver electrical energy. 2.3.1. Connection of Additional Battery Cells One or more additional rechargeable battery cells 110 can be connected to the modular battery network 180, thereby increasing the energy storage capacity of the mobile power supply 100. The additional rechargeable battery cells 110 are connected to the first high-power subsystem 120 and the second high-power subsystem 130, allowing them to receive and deliver inputs and outputs, respectively. The connection can be removable, for applications where flexibility is important, or the connection can be permanent, for applications where robustness and high storage capacity are important. 2.3.2. Power Delivery to Additional Battery Cells In some configurations of the mobile power supply 100, the modular battery network 180 is adapted to deliver power to additional rechargeable battery cells 110. This process involves the first high-power subsystem 120 and the second high-power subsystem 130, which are responsible for managing the flow of electrical energy within the system. The first high-power subsystem 120 receives a first direct current 160 from the DC input under the control of the first CCS protocol and delivers this current to the additional rechargeable battery cells 110. This process charges the additional battery cells, increasing the overall energy storage capacity of the mobile power supply 100. The second high-power subsystem 130, on the other hand, converts an output of the additional rechargeable battery cells 110 to a second direct current 170 and delivers this current to the DC output under the control of the second CCS protocol. This process allows the additional battery cells to deliver electrical energy when needed, thereby extending the operational time of the mobile power supply 100. Since the first high-power subsystem 120 and the second high-power subsystem 130 are common to all of the rechargeable battery cells 110, the system is easily scalable since there is no need to introduce additional high-power subsystems with the additional rechargeable battery cells 110. 2.4. Delivery of Direct Current by Mobile Power Supply Conversion Devices The mobile power supply 100 is adapted to be used with two mobile power supply conversion devices, namely the first mobile power supply conversion device 190 and the second mobile power supply conversion device 240. These devices are adapted to receive alternating (AC) current from external power sources and convert it to direct current (DC), which can then be delivered to the rechargeable battery cell 110 of the mobile power supply 100. The first mobile power supply conversion device 190 receives a first alternating current from a three-phase power supply, converts it to a first direct current 160, and delivers this current to the DC input of the CCS input connector 140 under the control of the first CCS protocol. This process allows the mobile power supply 100 to receive power from a three-phase power supply, which is a common type of power supply in many industrial and commercial settings. Advantageously, the output of the mobile power supply conversion device 190 can be a high-power DC current, enabling it to perform fast charging of the mobile power supply 100. The second mobile power supply conversion device 240, on the other hand, receives a second alternating current 230 from an electricity grid, converts it to a third direct current 250, and delivers this current to the rechargeable battery cell 110. This process allows the mobile power supply 100 to receive power from the electricity grid. Advantageously, the second mobile power supply conversion device 240 can be used to charge the mobile power supply 100 overnight when electricity rates are lower. Accordingly, it can be controlled by a pre-defined power schedule. The control steps described above can be implemented by the integrated CCS control system 280 by way of executable instructions stored in a memory 300 of the integrated CCS control system 280. 3. Potential Applications The mobile power supply 100 has a wide range of potential applications, including both stationary and mobile applications. It is scalable, making it adaptable to the specific needs of different applications. It can be used in remote or off-grid locations, providing a reliable power supply where traditional power sources may not be available. The mobile power supply 100 can be used to power a wide range of devices and systems, from small electronic devices to large machinery and equipment. The mobile power supply 100 may be configured to be connected to an electricity grid and charged overnight from the grid when electricity demands are lower. In turn, the mobile power supply 100 may be configured to return this charge to the electricity grid during peak hours, acting as an additional storage buffer for the electricity grid and helping the electricity grid to meet the peak demand. One of the most promising applications of the mobile power supply 100 is in the field of EV charging, which is discussed in more detail below. 3.1. Use of Direct Current for Charging EVs The mobile power supply 100 is adapted to deliver a direct current, which enables efficient charging of an EV. In practice, an EV could be connected to the CCS output connector 150 of the mobile power supply 100, and the vehicle's battery could be charged directly with the second direct current 170 delivered by the mobile power supply 100. 3.2. Use in Static Charging Stations The mobile power supply 100 can be used in static charging stations for EVs. Specifically, the mobile power supply 100 can be connected to a 3-phase AC supply using the mobile power supply conversion device 190, and the CCS output connector 150 of the mobile power supply 100 can be connected to an EV. Since the second direct current 170 can be delivered at high power via the CCS output connector 150, the EV can be charged fast. Hence, this arrangement essentially allows the mobile power supply 100 to be used as a fast charger for EVs, but without the usual construction works or landowner permissions being required for its installation. In other words, it can be installed much more cost-effectively and quickly than conventional fixed fast chargers. The modular battery network 180 and the modular mobile power supply arrangements allow for scalability, enabling the charging station to increase its energy storage capacity as needed by connecting additional rechargeable battery cells 110. 3.3. Use in Mobile Charging Solutions The mobile power supply 100 can also be used in mobile charging solutions for EVs. In practice, an EV could be connected to the mobile power supply 100 in a mobile charging setup, and the vehicle's battery could be charged directly with the second direct current 170 delivered by the mobile power supply 100. 3.4 Use as an AC Power Supply The mobile power supply 100 can be used with a DC to AC converter. Using these two components together results in an AC output, which can be used to power AC equipment off-grid.
