Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle battery detection, and more specifically, to a monitoring device for new energy vehicle batteries. Background Art

[0002] With the development of science and technology, energy-saving vehicles have gradually become mainstream. As the core component of new energy vehicles, batteries are the core components of the entire vehicle. Therefore, it is particularly important to detect the battery during driving. Among them, real-time monitoring of battery temperature is extremely important. During the driving process of the car, since the car often makes different movements, the battery will release a lot of heat in order to meet the normal driving requirements of the car. At this time, it is necessary to monitor the battery temperature in real time and cool the battery in time. Since the battery pack of some models is composed of multiple battery modules, and the space where the battery pack module is located is relatively closed, when the battery heats up, the traditional battery monitoring device cannot quickly discharge a large amount of heat, which may cause the battery temperature to be too high and then cause the battery performance to decline.

[0023] As attached Figure 1 To Attachment Figure 4 The present invention provides a monitoring device for a new energy vehicle battery, comprising:

[0024] Battery housing 1;

[0025] A cooling assembly 2, the cooling assembly 2 comprises a cooling pipe 21, a water pump 22, a water reservoir 23, a one-way valve 24, a connecting pipe 25, a pressure detector 26, a first connecting pipe 27, a heat dissipation pipe 28, and a second connecting pipe 29.

[0026] A reinforcing component 3, the top side of the reinforcing component 3 is fixedly connected to the bottom side of the battery housing 1;

[0027] An adjustment component 4, the adjustment component 4 is fixedly connected to the left side surface of the battery housing 1;

[0028] Specifically, the shape of the heat dissipation pipe 28 is set to be spiral. When the fan blades 33 rotate, the spiral design can discharge the heat of the water flow inside the heat dissipation pipe 28 more quickly.

[0029] Among them, the reinforcement component 3 includes a fan housing 31, a motor 32, and a fan blade 33. The top side of the fan housing 31 is fixedly connected to the bottom side of the battery housing 1, one end of the motor 32 is fixedly connected to the inner surface of the fan housing 31, and one end of the fan blade 33 is fixedly connected to the rotating shaft of the fan housing 31.

[0030] Among them, the adjustment component 4 includes a movable plate 41, an electric push rod 42, a temperature sensor 43, a sliding rod 44, a spring 45, and a pressure plate 46. One side surface of the movable plate 41 is fixedly connected to the left side surface of the battery housing 1, one end of the electric push rod 42 is fixedly connected to the inner surface of the movable plate 41, one side of the temperature sensor 43 is fixedly connected to the output end of the electric push rod 42, and a slide groove begins to be provided on the upper surface of the movable plate 41. One end of the sliding rod 44 is slidably connected inside the slide groove, and the other end of the sliding rod 44 is fixedly connected to one end of the spring 45. The side of the pressure plate 46 is fixedly connected to the other end of the spring 45, and one side of the temperature sensor 43 is fixedly connected to the other side of the pressure plate 46;

[0031] Specifically, the spring 45 presses the temperature sensor 43 against the left surface of the battery housing 1 through the pressure plate 46. When the electric push rod 42 is longer, the output end of the electric push rod 42 drives the temperature sensor 43 to slide on the left surface of the battery housing 1. At the same time, the temperature sensor 43 drives the pressure plate 46 to slide. The pressure plate 46 drives the sliding rod 44 to slide in the slide groove above the movable plate 41 through the spring 45.

[0032] The cooling pipes 21 are arranged on the front and rear sides of the battery housing 1, and the end faces of the cooling pipes 21 are arranged in a rectangular shape. The cooling pipes 21 on both sides are finally gathered together and fixedly connected to one end of the water pump 22 through a water pipe.

[0033] Specifically, a diverter valve is provided at the intersection of the cooling pipes 21 . When the water pump 22 pushes the cold water toward the cooling pipes 21 , the cold water will be evenly distributed to the front and rear sides of the battery housing 1 through the diverter valve.

[0034] The movable plate 41 is in a square shape, and the electric push rod 42 and the temperature sensor 43 are arranged in the middle of the movable plate 41 .

[0035] The working process of the utility model is as follows:

[0036] When working, first start the power supply of the water pump 22, and the water pump 22 pumps cold water from the water reservoir 23 into the cooling pipe 21. Then the cold water passes through the inside of the cooling pipe 21 to take away part of the heat on the surface of the battery housing 1. Then the water with heat will enter the heat dissipation pipe 28 through the second connecting pipe 29. In this process, start the power supply of the motor 32, and the shaft of the motor 32 drives the fan blades 33 to rotate. The rotation of the fan blades 33 accelerates the flow of air. The air is sucked in from one side of the fan housing 31 and blown to the surface of the heat dissipation pipe 28. At this time, the air will take away the heat of the water flow in the heat dissipation pipe 28. Then the water after cooling returns to the inside of the connecting pipe 25. At this time, the pressure detector 26 will measure the pressure of the water flow. The force is detected, and then the water flows through the one-way valve 24 and re-enters the water reservoir 23, thereby completing the cycle. The one-way valve 24 can prevent the water inside the water reservoir 23 from flowing back into the one-way valve 24, and the power supply of the electric push rod 42 is started. The electric push rod 42 extends and drives the temperature sensor 43 to slide on the left surface of the battery housing 1. At this time, the spring 45 applies a certain force to the pressure plate 46 to press the temperature sensor 43 against the left surface of the battery housing 1. At this time, as the temperature sensor 43 slides, the temperature sensor 43 drives the spring 45 through the pressure plate 46 to slide in the slide groove above the movable plate 41, and the position of the temperature sensor 43 can be changed by the extension and retraction of the electric push rod 42.
