Modular temperature-controlled energy storage device for automotive batteries

Abstract

This utility model belongs to the field of battery temperature control technology, specifically disclosing a modular temperature control energy storage device for automotive batteries, including: a side connection box, a heat exchange pipe, a temperature sensor, a return pipe, an output pipe, and a processing box. In use, when cooling is required, the electric heating wire is not activated. An electric pump drives the liquid flow in the pipeline system formed by the side connection box, heat exchange pipe, return pipe, and output pipe. The liquid absorbs heat through the heat exchange pipe and is cooled at the processing box. The processing box is cooled by airflow, releasing the heat from the internal liquid. When heating is required, typically when the car is just started, the vehicle speed is slow, and the gas flow rate on the surface of the processing box is slow. The electric heating wire and power supply terminals heat the internal liquid flow, and the heat is released to the battery through the heat exchange pipe, heating the battery's operating environment. Because the car speed is slow at this time, the heat loss due to airflow blowing onto the processing box is negligible.

Description

Technical Field

[0001] This utility model relates to the field of battery temperature control technology, specifically a modular temperature control energy storage device for automotive batteries. Background Technology

[0002] The specifics vary slightly depending on the type of electric vehicle. In pure electric vehicles equipped solely with a battery, the battery serves as the sole power source for the vehicle's drive system. In hybrid electric vehicles, which combine a conventional engine (or fuel cell) with a battery, the battery can function as either the primary or auxiliary power source for the drive system.

[0003] Car batteries generally operate best within a temperature range of 10-30 degrees Celsius (the optimal operating temperature range varies for different batteries; this range refers to the optimal operating temperature range for some regions). However, during car use, temperature differences vary greatly between different seasons and regions, making it difficult for cars to maintain the optimal operating temperature range. Some manufacturers have adopted methods to directly heat or cool the battery, usually using two sets of equipment, which takes up space and increases costs. Utility Model Content

[0004] The purpose of this invention is to provide a modular temperature-controlled energy storage device for automotive batteries to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular temperature-controlled energy storage device for automotive batteries, comprising:

[0006] Side connection box, heat exchange tube, temperature sensor, return pipe, output pipe, processing box;

[0007] The side connection box is centrally controlled, and two side connection boxes are provided. The two ends of the heat exchange tube are respectively connected to the two side connection boxes. The processing box is provided with a serpentine flow channel, and an electric heating wire is provided in the serpentine flow channel. The outer wall of the processing box is provided with a power supply terminal electrically connected to the electric heating wire.

[0008] The two ends of the serpentine flow channel are connected to the return pipe and the output pipe, respectively. The other end of the return pipe is connected to one of the side connection boxes, and the other end of the output pipe is connected to the other side connection box. An electric pump is installed on the output pipe.

[0009] The temperature sensor is located between the two side connection boxes. The signal output terminal of the temperature sensor is connected to the PLC controller. The output terminal of the PLC controller is electrically connected to the power supply circuit of the electric pump and the power supply terminal.

[0010] Preferably, a support rod is connected between the two side connecting boxes, and the temperature sensor is mounted on the support rod.

[0011] Preferably, the heat exchange tube and the processing box are both made of copper, and the return pipe and the output pipe are both made of double-layer heat-insulating pipes.

[0012] Preferably, heat dissipation fins are provided on both the upper and lower surfaces of the processing box.

[0013] Preferably, a connecting block is provided on the side wall of the processing box, the connecting block is connected to the outer wall of one of the side connecting boxes, and the PLC controller is mounted on the connecting block.

[0014] Preferably, a connecting plate is installed on the side wall of the side connecting box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] During use, when cooling is required, the electric heating wire is not activated. The electric pump drives the liquid flow in the piping system formed by the side connection box, heat exchange tube, return tube, and output tube. The liquid absorbs heat at the heat exchange tube and is cooled at the processing chamber. The processing chamber is cooled by airflow, causing the internal liquid heat to be released.

[0017] When heating is required, it is usually when the car is just started (the battery temperature will rise after the car is started). The car speed is slow at the start, and the gas flow rate on the surface of the treatment box is slow. The liquid flowing inside is heated by the electric heating wire and the power supply terminal. The heat is released to the battery through the heat exchange tube, heating the battery working environment. Since the car speed is slow at this time, the heat loss caused by the air blowing on the treatment box can be ignored. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example 1:

[0025] Please see Figure 1-3 This utility model provides a technical solution: a modular temperature control energy storage device for automobile batteries, comprising: a side connection box 1, a heat exchange tube 3, a temperature sensor 5, a return pipe 6, an output pipe 7, and a processing box 9;

[0026] The side connection box 1 is centrally controlled, and two side connection boxes 1 are provided. The two ends of the heat exchange pipe 3 are respectively connected to the two side connection boxes 1. The processing box 9 is provided with a serpentine flow channel 13, and an electric heating wire 14 is provided in the serpentine flow channel 13. The outer wall of the processing box 9 is provided with a power supply terminal 15 electrically connected to the electric heating wire 14. The two ends of the serpentine flow channel 13 are respectively connected to the return pipe 6 and the output pipe 7. The other end of the return pipe 6 is connected to one of the side connection boxes 1, and the other end of the output pipe 7 is connected to the other side connection box 1. An electric pump 8 is installed on the pipe of the output pipe 7. The temperature sensor 5 is located between the two side connection boxes 1. The signal output terminal of the temperature sensor 5 is connected to the PLC controller 12. The output terminal of the PLC controller 12 is electrically connected to the power supply circuit of the electric pump 8 and the power supply terminal 15.

[0027] Analysis of the above: Based on local environmental conditions and seasons, a suitable operating temperature threshold for the battery is preset and stored in the PLC controller 12. The side connection box 1, heat exchange pipe 3, temperature sensor 5, return pipe 6, output pipe 7, and processing box 9 are installed on the lower side of the car battery, with the temperature sensor 5 in contact with the surface of the car battery (if it is necessary to detect the internal temperature, the temperature sensor 5 can be extended into the interior of the car battery) for detecting the operating temperature of the car battery. The PLC controller 12 compares the temperature detected by the temperature sensor 5 with the suitable operating temperature threshold. When the detected temperature is within the suitable operating temperature threshold range, the status quo is maintained; when the detected temperature is greater than the suitable operating temperature threshold, cooling is required; when the detected temperature is less than the suitable operating temperature threshold, heating is required.

[0028] When cooling is required, the electric heating wire 14 is not in operation. The electric pump 8 drives the liquid flow in the pipeline system formed by the side connection box 1, heat exchange tube 3, return tube 6, and output tube 7. The liquid absorbs heat through the heat exchange tube 3 and is cooled at the processing tank 9. The processing tank 9 is cooled by airflow, which releases the heat from the liquid inside.

[0029] When heating is required, it is usually when the car is just started (the battery temperature will rise after the car is started). The car speed is slow at the start, and the gas flow rate on the surface of the treatment box 9 is slow. The liquid flowing inside is heated by the electric heating wire 14 and the power supply terminal 15. The heat is released to the battery through the heat exchange tube 3, which heats the battery working environment. Since the car speed is slow at this time, the heat loss caused by the air blowing on the treatment box can be ignored.

[0030] The PLC controller 12 uses existing technology to control the electric heating wire 14, power supply terminal 15, and electric pump 8. For example, the corresponding power supply circuits of the electric heating wire 14, power supply terminal 15, and electric pump 8 are controlled by relay switches to realize the operation control of the electric heating wire 14, power supply terminal 15, and electric pump 8.

[0031] Example 2:

[0032] Please see Figure 1-3 This utility model provides a technical solution: a support rod 4 is connected between the two side connecting boxes 1, and the temperature sensor 5 is installed on the support rod 4.

[0033] Analysis of the above: The support rod 4 can stably support the temperature sensor 5.

[0034] Example 3:

[0035] Please see Figure 1-3This utility model provides a technical solution: the heat exchange tube 3 and the processing box 9 are both made of copper, and the return pipe 6 and the output pipe 7 are both made of double-layer heat-insulating pipes.

[0036] Analysis of the above content: Copper has good thermal conductivity, which makes the heat exchange between heat exchange tube 3 and battery and the heat dissipation of processing box 9 better during cooling. The return pipe 6 and output pipe 7 adopt double-layer pipes, which have a heat insulation effect. In non-heat exchange positions, heat exchange is reduced, and there is a good heat preservation effect here.

[0037] Example 4:

[0038] Please see Figure 1-3 The present invention provides a technical solution: heat dissipation fins 10 are provided on both the upper and lower surfaces of the processing box 9.

[0039] Analysis of the above content: The heat dissipation fins 10 mainly play the role of increasing the surface contact with the air during the cooling process. When heating is required, due to the slow speed, the contact area is increased in time, and less heat is lost after the liquid is heated.

[0040] Example 5:

[0041] Please see Figure 1-3 This utility model provides a technical solution: a connecting block 11 is provided on the side wall of the processing box 9, the connecting block 11 is connected to the outer wall of one of the side connecting boxes 1, and the PLC controller 12 is mounted on the connecting block 11. A connecting plate 2 is installed on the side wall of the side connecting box 1.

[0042] Analysis of the above content: The connecting plate 2 is used to install and fix the side connecting box 1 as a whole with screws. When not in use, the whole temperature control device can be removed, which is modular in installation and disassembly.
