Description

Technology Field

[0001] The present invention relates to a fire safety device for performance testing of a power-based hybrid system and a method of operation thereof, and more specifically, to a fire safety device for performance testing of a power-based hybrid system and a method of operation thereof that prevents and suppresses a fire that may occur during the performance testing of a power-based hybrid system by using a cooling water supply device. Background Technology

[0003] Recently, the importance of safety devices and safety measures for performance testing of power-based hybrid systems has been highlighted.

[0004] A power-based hybrid system, comprising a fuel cell system, power conversion system, power distribution system, power load system, battery system, cooling module, and cooling water supply system, requires safety devices and appropriate control methods to prevent accidents such as fire and explosion that may occur during performance testing.

[0005] In addition, since a dedicated laboratory environment equipped with various safety measures is required for performance testing of power-based hybrid systems, general fire safety devices such as fire detection sensors and fire extinguishing systems are provided for laboratory safety management.

[0006] However, in the case of power-based hybrid systems, there is a possibility of fire and explosion due to electrical factors, chemical factors, and overheating, as they include hydrogen fuel cells, water electrolysis systems, power conversion systems, battery systems, and high-voltage cables.

[0007] In particular, energy storage systems (ESS), such as battery systems, have a high risk of fire due to thermal runaway, and if thermal runaway occurs, the fire spreads rapidly and is difficult to suppress.

[0008] Therefore, in the case of power-based hybrid systems, it is required to provide additional emergency fire response devices in addition to the basic fire safety devices equipped in the laboratory.

[0009] Meanwhile, conventional power-based hybrid systems use a cooling water supply device to set the operating temperature conditions of a normal test object.

[0010] However, since these conventional power-based hybrid systems use the cooling water supply device solely to set the operating temperature conditions of the test subject, there is a problem in that they cannot provide the function of an additional emergency fire response device capable of delaying battery thermal runaway and heat transfer phenomena in the components of the power-based hybrid system.

[0056] Hereinafter, embodiments of the present invention will be described in detail with reference to the relevant drawings.

[0058] FIG. 1 is a configuration diagram showing the configuration of a fire safety device for performance testing of a water-cooled power-based hybrid system according to one embodiment of the present invention, and FIG. 2 is a configuration diagram showing the configuration of a fire safety device for performance testing of a water-cooled and air-cooled power-based hybrid system according to another embodiment of the present invention.

[0059] Referring to FIGS. 1 and 2, a fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention may include a cooling water control unit (100), a heat blocking unit (200), and a battery cooling unit (300).

[0060] Specifically, a cooling water control unit (100) according to one embodiment of the present invention can control the cooling water supplied to a power-based hybrid system and supply it to a heat blocking unit (200) and a battery cooling unit (300).

[0061] More specifically, as illustrated in FIGS. 1 and 2, a cooling water control unit (100) according to one embodiment of the present invention is configured to include a cooling water supply system and a temperature and flow rate control controller, which are components of a power-based hybrid system, thereby enabling control of the cooling water supplied to the cooling module, heat blocking unit (200), and battery cooling unit (300) of the power-based hybrid system.

[0062] In addition, a cooling water control unit (100) according to one embodiment of the present invention can measure the temperature of a power-based hybrid system using an attached temperature sensor or a thermal imaging sensor installed at a plurality of locations of the power-based hybrid system.

[0063] Through this, the cooling water control unit (100) according to one embodiment of the present invention can control the cooling water supplied to the heat blocking unit (200) and the battery cooling unit (300) according to the temperature of the components of the power-based hybrid system.

[0064] Here, the components of the power-based hybrid system may include a fuel cell, a battery, a power distribution device, a power conversion system, and cables.

[0065] Additionally, as illustrated in FIGS. 1 and 2, a fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention may further include a heat cutoff control valve (400) that controls the cooling water supplied to the heat cutoff unit (200) by opening and closing according to a cooling water control signal received from the cooling water control unit (100).

[0066] For example, a heat blocking control valve (400) according to one embodiment of the present invention can control the flow rate of cooling water supplied to the heat blocking unit (200) in real time using a proportional control method.

[0067] Specifically, the heat cutoff control valve (400) according to one embodiment of the present invention utilizes a proportional control method that can continuously adjust the degree of valve opening, thereby enabling fine adjustment of the flow rate of the cooling water supplied to the heat cutoff unit (200) according to the control of the cooling water control unit (100) based on the temperature change of the fuel cell and power conversion system.

[0068] In addition, the heat cutoff control valve (400) according to one embodiment of the present invention is preferably composed of a solenoid valve that controls the opening and closing of the valve by flowing current through an electrical signal to form a magnetic field, but is not limited thereto, and any device or means capable of continuously adjusting the degree of opening of the valve using a proportional control method according to the control of the cooling water control unit (100) may be applied.

[0069] Subsequently, a cooling water control unit (100) according to one embodiment of the present invention can transmit a cooling water control signal to a heat cutoff control valve (400) to control the opening and closing of the heat cutoff control valve (400) using a wired or wireless communication method.

[0070] Here, wired and wireless communication methods may refer to wired communication methods including CAN (Controller Area Network), RS-485 and Modbus (RTU / TCP) and wireless communication methods including Bluetooth, Zigbee and 5G / LTE (Cellular IoT).

[0071] A heat blocking control valve (400) according to one embodiment of the present invention can open the valve and change the direction of the cooling water when it receives a cooling water control signal from a cooling water control unit (100), thereby supplying cooling water to a heat blocking unit (200).

[0072] As illustrated in FIGS. 1 and 2, a heat blocking unit (200) according to one embodiment of the present invention can receive cooling water from a heat blocking control valve (400) when the heat blocking control valve (400), which has received a cooling water control signal from a cooling water control unit (100), opens the valve.

[0073] In addition, a heat blocking unit (200) according to one embodiment of the present invention can block heat diffusing in the space between each of the fuel cell, battery, power distribution device, or power conversion system using cooling water supplied to the power-based hybrid system.

[0074] Here, a heat blocking unit (200) according to one embodiment of the present invention is installed in the space between each of a fuel cell, a battery, a power distribution device, or a power conversion system, and an internal flow path through which coolant travels may be formed as a partition structure.

[0075] For example, a heat blocking member (200) according to one embodiment of the present invention may be installed in close contact with the shape of a component of a power-based hybrid system by forming an internal flow path with heat-resistant silicone, which is a flexible material.

[0076] That is, the heat blocking unit (200) according to one embodiment of the present invention is preferably installed at the location shown in FIGS. 1 and 2, but is not limited thereto, and can be installed at a location where heat conduction occurs between power-based hybrid system components depending on the shape of the power-based hybrid system components to block heat diffusion.

[0077] Accordingly, the heat blocking unit (200) according to one embodiment of the present invention can be connected in series or parallel between internal flow paths depending on the shape of the power-based hybrid system components, and can be connected in the longitudinal or transverse direction.

[0078] By doing so, the fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention can effectively block heat conduction occurring between components according to the form of the components of the power-based hybrid system including a fuel cell, a power conversion system, a battery, and a cable.

[0079] In addition, in a fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention, cooling water flowing through an internal path of a heat blocking unit (200) is initially introduced by a cooling water control unit (100) into a heat blocking module (200) located in the space between a fuel cell system and a power conversion system, and the introduced cooling water can pass through a heat blocking module (200) located in the space between a power conversion system and a power distribution device, and then flow into a heat blocking module (200) located in the space between a power distribution device and a battery system.

[0080] However, it is not limited to this, and cooling water may be supplied first to a heat blocking module (200) installed in the space between the system or device constituting the power-based hybrid system where heat generation is most severe.

[0081] For example, a fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention can supply cooling water to all heat blocking modules (200), including a heat blocking module (200) installed in the space between a fuel cell system and a power conversion system, a heat blocking module (200) installed in the space between a power conversion system and a power distribution device, and a heat blocking module (200) installed in the space between a power distribution device and a battery system, by connecting a heat blocking control valve (400) and a heat blocking unit (200) in parallel.

[0082] Meanwhile, a battery cooling unit (300) according to one embodiment of the present invention can cool the battery by immersing it in the cooling water of a power-based hybrid system.

[0083] Here, a battery cooling unit (300) according to one embodiment of the present invention may include a liquid immersion tank (310) and a cooling water spray nozzle (320).

[0084] A liquid immersion tank (310) according to one embodiment of the present invention may be formed to immerse a battery, and a cooling water spray nozzle (320) according to one embodiment of the present invention may spray cooling water into the liquid immersion tank (310).

[0085] Specifically, according to one embodiment of the present invention, the liquid immersion tank (310) can immerse the battery by receiving a cooling water control signal from the cooling water control unit (100) when a temperature above a preset temperature is detected by any one of the temperature measuring sensors of the cooling water control unit (100) installed at a plurality of locations of the power-based hybrid system.

[0086] For example, the cooling water control unit (100) may pre-set a temperature that determines a plurality of fire occurrences in the power-based hybrid system, and if a temperature above the pre-set temperature is detected by any one of the plurality of temperature measurement sensors, it may transmit a cooling water control signal to the liquid immersion tank (310) of the battery cooling unit (300).

[0087] Afterwards, when the immersion tank (310) receives a cooling water control signal from the cooling water control unit (100), it can immerse the battery in the tank equipped with cooling water.

[0088] In addition, when the cooling water spray nozzle (320) according to one embodiment of the present invention receives a cooling water control signal from the cooling water control unit (100), it sprays cooling water into the liquid immersion tank (310) by adjusting the spray angle, flow rate, or pressure according to the cooling water control signal, and can remove toxic gases or fine particles generated from a fire in the battery using the sprayed cooling water.

[0089] Specifically, a cooling water spray nozzle (320) according to one embodiment of the present invention can remove toxic gases or fine particles generated during a battery fire by adjusting the spray pattern according to a cooling water control signal to spray cooling water evenly over a wide area or by concentrating spraying at a specific point, thereby generating a water scrubber effect.

[0090] By doing so, the cooling water spray nozzle (320) according to one embodiment of the present invention can directly cool the battery or fill the immersion tank (310) with cooling water and immerse the battery in the immersion tank (310) by spraying cooling water onto the immersion tank (310) and the battery immediately upon receiving a cooling water control signal from the cooling water control unit (100).

[0091] Additionally, as illustrated in FIGS. 1 and 2, a cooling water spray nozzle (320) according to one embodiment of the present invention can spray cooling water supplied from a cooling water control unit (100) and cooling water supplied from a heat blocking unit (200) into a liquid immersion tank (310).

[0092] A fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention may further include a battery cooling control valve (500) that controls the cooling water supplied to the battery cooling unit (300) by opening and closing according to a cooling water control signal received from a cooling water control unit (100).

[0093] Specifically, a battery cooling control valve (500) according to one embodiment of the present invention can supply cooling water to a battery cooling unit (300) using an ON-OFF control method when the valve is opened according to a cooling water control signal.

[0094] Here, the on / off control method may mean a control method in which the battery cooling control valve (500) fully opens or closes the valve as soon as it receives a cooling water control signal from the cooling water control unit (100).

[0095] Additionally, the battery cooling control valve (500) according to one embodiment of the present invention is preferably composed of a solenoid valve that controls the opening and closing of the valve by flowing current through an electrical signal to form a magnetic field, but is not limited thereto, and any device or means capable of immediately opening the valve using an on / off control method according to the control of the cooling water control unit (100) may be applied.

[0096] Through this, the battery cooling control valve (500) according to one embodiment of the present invention can supply cooling water to the cooling water injection nozzle (320) by controlling the opening and closing of the valve and the direction of cooling water flow according to the received cooling water control signal, as shown in FIGS. 1 and 2.

[0097] That is, according to one embodiment of the present invention, the battery cooling unit (300) can receive the cooling water from the heat blocking unit (200) and the cooling water directly supplied from the cooling water control unit (100) through the battery cooling control valve (500) in accordance with the cooling water control signal of the cooling water control unit (100), and cool the battery by immersing it.

[0098] In addition, a fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention may further include a liquid immersion tank control valve (600) that controls the cooling water inside the liquid immersion tank (310) to recover the cooling water supplied to the liquid immersion tank (310).

[0099] A liquid immersion tank control valve (600) according to one embodiment of the present invention can open the valve in accordance with a cooling water control signal received from a cooling water control unit (100) to recover cooling water inside the liquid immersion tank (310).

[0100] For example, a cooling water control unit (100) according to one embodiment of the present invention measures the temperature of the battery, and if the measured temperature of the battery decreases to a preset temperature or lower, it determines that the fire of the battery has been extinguished and transmits a cooling water control signal to the liquid immersion tank control valve (600).

[0101] Subsequently, when the liquid immersion tank control valve (600) according to one embodiment of the present invention receives a cooling water control signal from the cooling water control unit (100), the valve is opened to recover the cooling water inside the liquid immersion tank (310), thereby allowing it to be reused for performance testing of a power-based hybrid system under the control of the cooling water control unit (100).

[0102] Specifically, the coolant reused by the coolant control unit (100) can be supplied to the cooling module, heat blocking unit (200), and battery cooling unit (300) of the power-based hybrid system.

[0104] In summary, the cooling water control unit (100) of the fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention can circulate and supply cooling water to the cooling module and the heat blocking unit (200) of the power-based hybrid system.

[0105] By doing so, the fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention can effectively prevent the occurrence of a fire in the power-based hybrid system by preventing heat diffusion due to heat generation of the components of the power-based hybrid system.

[0106] On the other hand, a fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention can block thermal runaway caused by fire in the battery by transmitting a cooling water control signal to a battery cooling unit (300) and a battery cooling control valve (400) when the cooling water control unit (100) detects a temperature above a preset temperature in the power-based hybrid system and determines that a fire has occurred, thereby immersing the battery in the cooling water.

[0107] In addition, the fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention can recover the cooling water sprayed into the liquid immersion tank (310) of the battery cooling unit (300) through the control of the cooling water control unit (100) when the temperature of the power-based hybrid system decreases and changes to a normal state, and reuse it in the power-based hybrid system and the fire safety device (1000).

[0109] FIG. 3 is a flowchart illustrating the operation method of a fire safety device for performance testing of a power-based hybrid system according to one embodiment of the present invention.

[0110] Referring to FIG. 3, the operation method of a fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention may include steps S100, S200, and S300.

[0111] In step S100, a cooling water control unit (100) that controls the cooling water supplied to the power-based hybrid system can supply cooling water to a heat blocking unit (200) placed in the space between each of the fuel cell, battery, power distribution device, or power conversion system.

[0112] Additionally, in step S100, the cooling water control unit (100) may further include a step of controlling a heat blocking control valve (400) connected to the heat blocking unit (200) to supply cooling water to the heat blocking unit (200) and thereby controlling the flow rate of cooling water supplied to the heat blocking unit (200).

[0113] Specifically, in step S100, the cooling water control unit (100) transmits a cooling water control signal to the heat cutoff control valve (400), and when the heat cutoff control valve (400) receives the cooling water control signal, the heat cutoff control valve (400) can adjust the temperature and flow rate of the cooling water supplied to the heat cutoff unit (200) in real time using a proportional control method according to the cooling water control signal received from the cooling water control unit (100).

[0114] In step S200, the cooling water control unit (100) can measure the temperature using temperature measurement sensors installed at multiple locations of the power-based hybrid system.

[0115] In step S300, when a temperature above a preset level is measured at any one of the multiple locations and the cooling water control unit (100) transmits a cooling water control signal to the battery cooling unit (300) that cools the battery, the battery cooling unit (300) can immerse the battery in a liquid immersion tank.

[0116] Additionally, in step S300, when the battery cooling unit (300) receives a cooling water control signal from the cooling water control unit (100), the step of the cooling water injection nozzle (320) of the battery cooling unit (300) spraying cooling water into the immersion tank (310) may be further included.

[0117] Specifically, in step S300, when the cooling water control unit (100) determines that a fire has occurred at a location where a temperature above a preset temperature is measured at any one of a plurality of locations, it transmits a cooling water control signal to the battery cooling unit (300). When the battery cooling unit (300) receives the cooling water control signal, the cooling water spray nozzle (320) sprays cooling water into the immersion tank (310), thereby immersing the battery in the immersion tank (310) to cool it.

[0118] More specifically, in step S300, when the battery cooling unit (300) and the battery cooling control valve (400) receive a cooling water control signal from the cooling water control unit (100), the battery cooling control valve (400) immediately opens the valve using an on / off control method to supply cooling water to the battery cooling unit (300), and the battery cooling unit (300) can spray the cooling water supplied from the battery cooling control valve (400) onto the liquid immersion tank (310) and the battery through the cooling water spray nozzle (320).

[0119] Additionally, in step S300, when the temperature of the battery immersed in the immersion tank (310) decreases to below a preset temperature, the method may further include a step of recovering the cooling water supplied to the immersion tank (310) through the immersion tank control valve (600) that controls the cooling water inside the immersion tank (310).

[0120] Specifically, in step S300, when the battery immersed in the liquid immersion tank (310) is cooled and the temperature of the battery decreases to below a preset temperature, the cooling water control unit (100) can transmit a cooling water control signal to the liquid immersion tank control valve (600).

[0121] Accordingly, when the liquid immersion tank control valve (600) receives a cooling water control signal from the cooling water control unit (100), the cooling water of the liquid immersion tank (310) can be recovered and reused for cooling the power-based hybrid system.

[0123] That is, according to the method of operation of the fire safety device (1000) for performance testing of a power-based hybrid system according to one embodiment of the present invention, the cooling water of the power-based hybrid system can be supplied to the heat blocking unit (200) and the battery cooling unit (300) through the control of the cooling water control unit (100).

[0124] By doing so, the heat diffusing between the components of the power-based hybrid system during performance testing of the power-based hybrid system is blocked through a heat blocking unit (200) using cooling water, thereby minimizing malfunction and damage to the components of the power-based hybrid system caused by heat generation.

[0125] In addition, when a high temperature is detected at any location during a performance test of a power-based hybrid system and the cooling water control unit (100) determines that a fire has occurred, the battery is immediately immersed and cooled to prevent thermal runaway caused by the fire in the battery, thereby preventing a secondary fire in the laboratory.

[0126] In addition, harmful gases and fine dust generated from battery fires can be removed due to the water scrubber effect caused by coolant injection.

[0127] In addition, by forming the structure of the internal flow path of the heat blocking section (200) according to the shape of the power-based hybrid system component, the fire safety device (1000) according to the present invention can be applied in a performance test environment where various types of components, such as fuel cells or batteries, are used.
