TECHNICAL FIELD
[0001] The present application relates to the technical field of emergency handling of vehicle charging test, and more particularly to a charging test vehicle emergency handling device. BACKGROUND
[0002] The current new energy vehicle power battery generally adopts lithium ion battery, and the following significant features exist in the thermal runaway fire in the charging test: (1) internal chain reaction: the fire is caused by the violent chemical exothermic reaction in the battery, and the external fire extinguishing agent is difficult to penetrate into the battery cell to terminate the reaction, which is only a temporary solution; (2) easy to rekindle: after the open fire is extinguished, a large amount of heat is still accumulated in the battery pack, and the battery cell may cause combustion again, which requires long time continuous cooling; (3) explosion and toxic gas risk: thermal runaway can instantaneously release a large amount of flammable and explosive electrolyte volatile gas (such as DMC, EC, etc.) and highly toxic hydrogen fluoride (HF) gas, which has a great risk of violent explosion and poisoning. At present, the traditional fire fighting method is mainly used, that is, personnel hold gas fire extinguisher into the warehouse or water-based fire extinguisher. However, this traditional method has the defects of low extinguishing efficiency, high risk and slow response. Therefore, how to efficiently link with the fire alarm system to automatically start the dragging program at the first time of fire confirmation, and transfer the dangerous source before the fire expands and the environment warehouse is damaged, has important significance.

[0028] To more clearly illustrate the specific embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly described below.

[0032] To enable those skilled in the art to better understand the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and implementation methods.
[0033] To address the problems of slow response, low efficiency, and high risk in current emergency response for vehicle charging tests, this invention provides an emergency response device for charging test vehicles. This device solves the problems of slow response, low efficiency, and high risk associated with the current practice of using personnel with fire extinguishers to extinguish fires during vehicle charging tests. It can transfer the hazard source before the fire spreads and the environmental compartment is damaged, thereby improving the automation and safety of emergency response for vehicle charging tests.
[0034] like Figs. 1-3 As shown, an emergency handling device for a charging test vehicle includes: a PLC controller, an explosion-proof motor 8, a gearbox 9, a drive winch 7, and a traction cable 4. A safety zone 6 is set up directly in front of the environmental chamber 1 used for charging tests. Automatic fire-fighting equipment is installed on both sides and the top of the safety zone 6. A concrete base 10 is located directly in front of the safety zone 6. The explosion-proof motor 8, the gearbox 9, and the drive winch 7 are mounted on the concrete base 10. The explosion-proof motor is driven and connected to the drive winch through the gearbox. The traction cable 4 is wound around the drive winch 7, and one end of the traction cable 4 is connected to the test vehicle located in the environmental chamber via a traction component. The PLC controller is signal-connected to the explosion-proof motor. When a fire alarm is received in the environmental chamber, it controls the explosion-proof motor 8 to operate, causing the drive winch 7 to rotate at high speed, forcefully retrieving the traction cable 4, pulling the test vehicle 2 into the safety zone, and controlling the automatic fire-fighting equipment to extinguish and cool the test vehicle 2.
[0035] Specifically, before the test begins, the operator drives the test vehicle 2 into the designated location within the vehicle's environmental chamber 1. Using a high-strength mechanical connector, the operator manually and securely connects the pre-set traction point 3 on the vehicle chassis to the end of the traction cable 4 extending from the drive winch 7. After connection, the PLC controller continuously monitors the linkage signals from the environmental chamber's fire alarm system. During the test, if the vehicle battery experiences thermal runaway, the smoke, temperature, or gas sensors within the chamber will detect the fire first and send a high-priority start command to the central fire alarm control panel and the device's PLC controller. This controls the explosion-proof motor to rotate, amplifying the motor torque through the gearbox, driving the winch to rotate at high speed, and forcefully retrieving the traction cable 4. The immense traction force acts directly on the vehicle's traction point 3 through the cable. This force is sufficient to overcome the locking force of the vehicle's electronic or mechanical handbrake, and even cause locked tires to slide within the guide groove, thereby forcibly towing the vehicle away from its original position. The guide groove ensures the vehicle is forcibly towed out of the environmental chamber 1 along a straight path and into a safe area. At this point, the vehicle and the towing unit remained rigidly connected by cables and continued to burn within the safe zone. Then, professional firefighters, wearing protective suits, used the fixed fire-fighting facilities in the safe zone to centrally extinguish and cool the vehicle, ensuring safety. After the fire was extinguished, the entire system was manually reset. This device ensures personnel safety; from fire detection to vehicle removal, no human intervention is required, completely eliminating the possibility of injury or death in high-risk environments such as deflagration, toxic gases, and high temperatures, achieving inherent safety. By rapidly removing the burning vehicle—a huge source of fire and pollution—the device effectively prevented the destruction of millions of dollars worth of precision testing equipment within the environmental chamber by fire, high temperatures, and toxic fumes, preserving the company's core R&D assets and minimizing losses. It also improves the automation and safety of emergency handling during vehicle charging tests.
[0036] The device also includes: a force sensor; the force sensor is mounted on the traction cable and is used to detect the traction force of the traction cable; the PLC controller is connected to the force sensor signal and reports an overload alarm when the traction force is greater than a set threshold.
[0037] The device also includes an alarm device; the alarm device is connected to the PLC controller via a signal, and the PLC controller controls the alarm device to sound an alarm when the traction force is greater than a set threshold.
[0038] Furthermore, the alarm device is at least one of the following: a buzzer, an indicator light, and an audible and visual alarm.
[0039] The device also includes: a length sensor; the length sensor is located at the drive winch and is used to detect the traction length of the traction cable; the PLC controller is connected to the length sensor and controls the explosion-proof motor to stop operating when the traction length is less than a set length threshold, so that the test vehicle stops in the set area.
[0040] Furthermore, the length sensor is a laser rangefinder.
[0041] In practical applications, when the length sensor detects that the cable has been retracted to the predetermined length, that is, when the vehicle has been towed to a safe outdoor area, the PLC controls the explosion-proof motor to stop working.
[0042] The device also includes a cable guide groove 5; the cable guide groove 5 is provided between the drive winch and the environmental chamber, so that the traction cable slides along the cable guide groove 5.
[0043] Furthermore, the PLC controller is connected to the fire alarm signal in the environmental chamber. Upon receiving the fire alarm signal, it controls the explosion-proof motor to operate at maximum torque, driving the drive winch to rotate at high speed and forcefully retrieving the traction cable.
[0044] The device also includes: a photoelectric sensor; the photoelectric sensor is set at a set position in the safety zone to detect whether the test vehicle towed to the safety zone has reached the set position; the PLC controller is connected to the photoelectric sensor and controls the explosion-proof motor to stop operating when the test vehicle reaches the set position, so that the test vehicle stops at the set position.
[0045] The device also includes: a display screen; the PLC controller is connected to the display screen via a signal, and the PLC controller controls the display screen to display the traction length and the traction force in real time when the test vehicle is being towed.
[0046] As can be seen, the present invention provides an emergency handling device for charging test vehicles. The PLC controller is connected to the explosion-proof motor signal. When a fire alarm is received in the environmental chamber, the explosion-proof motor is controlled to operate, so that the test vehicle is pulled into the safe area by the high-speed rotation of the drive winch. Then, the automatic fire-fighting equipment is controlled to extinguish the fire on the test vehicle. This solves the problem that the existing emergency handling of vehicle charging tests relies on personnel to extinguish fires with fire extinguishers, which has the problems of slow response, low efficiency and high risk. It can transfer the hazard source before the fire spreads and the environmental chamber is damaged, thus improving the automation and safety of emergency handling of vehicle charging tests.

The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures.
