Description

Technical Field

[0001] The utility model relates to the technical field of energy storage equipment, in particular to a charge and discharge monitoring device for an electrochemical battery used for energy storage. Background Art

[0002] The charging and discharging process of electrochemical cells for energy storage is the key link in achieving the storage and release of electrical energy. This process involves chemical reactions inside the battery, through which electrical energy is converted into chemical energy for storage and then converted back into electrical energy when needed.

[0003] During the charging and discharging process, the performance of the battery is affected by many factors, including the chemical properties of the battery materials, the structural design of the battery, the charging and discharging rate, temperature, etc. In order to ensure the safety and stable performance of the battery, the charging and discharging process usually needs to be strictly controlled and managed, including setting the appropriate charging and discharging current and voltage range, monitoring the temperature and internal state of the battery, and especially the need to accurately monitor the battery cell temperature to avoid explosion or natural disasters caused by excessive temperature.

[0004] Factors such as long-term overcharging of the battery cell, battery short circuit, high temperature and thermal runaway may cause the chemical reaction inside the battery to get out of control, thus causing an explosion. In addition, metallic lithium itself is active and is very likely to undergo chemical reactions in a humid environment, releasing hydrogen, which may also cause the battery to spontaneously combust. Therefore, in order to ensure the safe operation of energy storage batteries, a series of measures need to be taken to prevent the battery cell from overheating, including setting the appropriate charge and discharge current and voltage range, monitoring the battery's temperature and internal state, and avoiding battery short circuits.

[0005] In addition, when the ambient temperature is too low, the following problems may also occur: 1. Reduced charging efficiency: In a low temperature environment, the chemical reaction rate inside the battery will slow down, resulting in longer charging time and lower charging efficiency. 2. Reduced discharge performance: In a low temperature environment, the viscosity of the electrolyte inside the battery increases, and the diffusion rate of lithium ions in the carbon negative electrode slows down, which reduces the discharge performance of the battery, limits the power output of the vehicle, and reduces the acceleration performance. 3. Shortened battery life: Long-term use of the battery in a low temperature environment will lead to the loss of active substances inside the battery, thereby shortening the battery life. Therefore, in order to ensure the normal operation of the energy storage battery and extend its service life, it is necessary to heat the battery in a low temperature environment and increase the temperature of the battery to ensure its charging and discharging performance and safety.

[0006] There are several ways to detect the temperature of electrochemical batteries for energy storage: 1. Use a thermometer: stick the thermometer on the surface of the battery, wait for a while and read the temperature value. This method is simple and easy, but it may be affected by the uneven temperature distribution on the battery surface. 2. Use an infrared thermometer: This is a non-contact temperature detection method that obtains the temperature value by measuring the infrared radiation on the surface of the battery. This method is fast and convenient, but the accuracy may be affected by environmental factors. 3. Use a thermistor: A thermistor is a temperature sensing element whose resistance value changes with temperature. By measuring the resistance value of the thermistor, the battery temperature can be inferred. This method has high accuracy, but it requires connecting the circuit and is relatively complicated. 4. Use a battery tester: A battery tester is a professional testing equipment that can simultaneously measure battery parameters such as voltage, current and temperature. This equipment has high accuracy and comprehensive functions, but the price is relatively high. None of the above implementations can meet the detection needs of electrochemical battery modules for energy storage. Summary of the invention

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0041] Please refer to Figure 1The embodiment of the utility model provides an electrochemical battery charge and discharge monitoring device 2 for energy storage, which monitors the charge and discharge of an electrochemical battery module 1 for energy storage; the charge and discharge monitoring device 2 includes: a temperature detection component, a first temperature adjustment component, a second temperature adjustment component and a battery monitoring management component; the electrochemical battery module 1 for energy storage includes a shell 11 and a plurality of battery cells 12 arranged in a matrix inside the shell 11, and a heat dissipation air duct inlet 111 and a heat dissipation air duct outlet 112 are provided on the shell 11; the temperature detection component includes a plurality of temperature sensors 21, and the plurality of temperature sensors 21 are respectively provided Between the inner wall of the electrochemical battery module 1 for energy storage and two adjacent battery cells 12, the temperature sensor 21 is electrically connected to the battery monitoring and management component; the first temperature adjustment component is arranged on the outside of the shell 11, and is respectively connected to the heat dissipation duct inlet 111 and the heat dissipation duct outlet 112 pipeline, and is electrically connected to the battery monitoring and management component; the second temperature adjustment component is arranged inside the shell 11, and is electrically connected to the battery monitoring and management component; the battery monitoring and management component receives the temperature detection value of the battery cell 12 of the temperature detection component, and controls the first temperature adjustment component and / or the second temperature adjustment component to adjust the real-time temperature value inside the electrochemical battery module 1 for energy storage according to the temperature detection value of the battery cell 12.

[0042] Furthermore, the battery monitoring and management component is electrically connected to the control module of the electrochemical battery module 1 for energy storage, and starts the first temperature adjustment component and / or the second temperature adjustment component according to the start signal of the electrochemical battery module 1 for energy storage.

[0043] When the electrochemical battery module 1 for energy storage starts the charging function or the discharging function, its control module sends a start signal to the battery monitoring and management module. After receiving the start signal, the battery monitoring and management module controls the temperature detection component to detect the real-time temperature values ​​at various locations in the shell 11 of the electrochemical battery module 1 for energy storage, and determines the timing of starting the first temperature adjustment component and / or the second temperature adjustment component according to the temperature change.

[0044] Furthermore, several temperature sensors 21 in the temperature detection component are respectively arranged on the inner wall of the shell 11 of the electrochemical battery module 1 for energy storage, and the center and edge positions of the matrix of several battery cells 12 arranged in a matrix; the battery monitoring and management component respectively receives multiple real-time temperature values ​​of the temperature sensors 21 located at each position; when the maximum value among the multiple real-time temperature values ​​is greater than the upper limit value of the preset temperature range, the battery monitoring and management component controls the first temperature adjustment component to start, and when the minimum value among the multiple real-time temperature values ​​is less than the lower limit value of the preset temperature range, the battery monitoring and management component controls the second temperature adjustment component to start.

[0045] By detecting the real-time temperature values ​​at various locations of the shell 11 of the electrochemical battery module 1 for energy storage, especially the temperature values ​​set between several battery cells 12, the detection accuracy of the temperature of the battery cells 12 can be greatly improved, and the specific location of the maximum temperature value inside the shell 11 can be obtained. Based on whether the maximum temperature value is higher than the upper limit value of the preset temperature range, if so, it is determined that the temperature value inside the battery cell 12 is higher than the appropriate temperature range, and the first temperature control component is immediately started, and external air is blown into the shell 11 through a high-power fan, so that the temperature inside the shell 11 is quickly cooled down by gas convection.

[0046] In addition, when the temperature value detected by the temperature sensor 21 inside the shell 11 close to the shell 11 is lower than the lower limit of the preset temperature range, it is determined that the ambient temperature is too low and is not suitable for battery operation. The first temperature control component and / or the second temperature control component are controlled to start, heat the gas in the shell 11, and increase the ambient temperature of the battery cell 12.

[0047] Furthermore, the first temperature control component includes: a first fan 221 and a second fan 222 electrically connected to the battery monitoring and management component; the first fan 221 is respectively connected to the outside of the shell 11 and the heat dissipation duct inlet 111 on the shell 11, and blows the air outside the shell 11 into the inside of the shell 11 under the control of the battery monitoring and management component; the second fan 222 is respectively connected to the outside of the shell 11 and the heat dissipation duct outlet 112 of the shell 11, and discharges the hot air inside the shell 11 into the inside of the shell 11 under the control of the battery monitoring and management component.

[0048] Furthermore, the first temperature regulating component also includes a circulation pipeline 223 arranged on the first fan 221 and the second fan 222; a first valve 224 is provided at the pipeline end connecting the first fan 221 to the outside of the shell 11, a second valve 225 is provided at the pipeline end connecting the second fan 222 to the outside of the shell 11, and a third valve 226 is provided on the circulation pipeline 223 between the first fan 221 and the second fan 222; the battery monitoring and management component is electrically connected to the first valve 224, the second valve 225, and the third valve 226 respectively; when the battery monitoring and management component starts the first temperature regulating component, the first valve 224 and the second valve 225 are opened, and the third valve 226 is closed, so as to control the first temperature regulating component to dissipate heat and cool the inside of the shell 11; when the battery monitoring and management component starts the second temperature regulating component, the first valve 224 and the second valve 225 are closed, and the third valve 226 is opened, so as to control the second temperature regulating component to heat the inside of the shell 11, and at the same time control the first temperature regulating component to circulate the gas inside the shell 11 to increase the gas circulation speed.

[0049] When the first valve 224 and the second valve 225 are opened and the third valve 226 is closed, the first temperature control component is in a heat dissipation working mode, replacing the hot air in the shell 11 with cold air outside the shell 11 in a convection manner, and cooling the battery cell 12 by a strong airflow; when the first valve 224 and the second valve 225 are closed and the third valve 226 is closed, it is in a heating working mode, heating the gas around the battery cell 12 by a sheet heating unit 231 arranged around the battery cell 12 and a filament heating unit 232 arranged in the circulation pipeline 223, and forming an internal circulation of the gas by the first fan 221 and the second fan 222, thereby improving the balance of the temperature inside the shell 11 and avoiding the situation where the temperature of some areas in the shell 11 meets the temperature requirements while the temperature of other areas does not meet the requirements.

[0050] Furthermore, the heat dissipation duct inlet 111 is arranged at the bottom of one side wall of the shell 11, and the heat dissipation duct outlet 112 is arranged at the top of the opposite side wall of the shell 11; the electrochemical battery module 1 for energy storage also includes: a hollow structure battery cell support frame, and a plurality of battery cells 12 located on the battery cell support frame are spaced apart from the top and bottom of the shell 11 by a first preset distance.

[0051] The multiple battery cells 12 arranged on the battery cell support frame maintain a certain distance from the bottom and top of the shell 11, so that a gas flow passage that meets the requirements can be formed inside the shell 11, ensuring the gas flow rate, realizing the regulation of the battery cell 12 temperature, and ensuring the regulation effect.

[0052] Furthermore, the second temperature control component includes: a plurality of sheet heating units 231 electrically connected to the battery monitoring and management components respectively; the plurality of sheet heating units 231 are respectively arranged between two adjacent battery cells 12 on the bottom upper side and the top lower side of the battery cell support frame.

[0053] Optionally, the sheet heating unit 231 can be a resistance heater, which uses a resistor sheet as a heating element and generates heat by passing an electric current through the resistor sheet. The resistor sheet is usually made of metal or alloy, and has good electrical conductivity and high temperature resistance. In addition, the sheet heating unit 231 can also be a ceramic heater, which uses a ceramic material as a heating element and generates heat by passing an electric current through the ceramic material. Ceramic materials have high thermal conductivity and good high temperature resistance, so this heater usually has higher heating efficiency.

[0054] By arranging the sheet heating unit 231 at the top and bottom of two adjacent battery cells 12 and fixedly connecting them to the battery cell support frame, a passage for gas flow is retained between the two adjacent battery cells 12. When the device is in a heat dissipation mode or a heating mode, cold gas or hot gas can flow smoothly between the two battery cells 12 distributed in a matrix, thereby ensuring the heat dissipation or heating effect.

[0057] The filament heating unit 232 can be a heating wire, which is a common implementation in linear heaters. They can be customized into various lengths and are easy to install and control. Heating wires are usually used for lower temperature applications. Resistance band heaters can also be used: resistance bands are usually made of metal or alloy, can be customized into various lengths and shapes, and are suitable for various linear heating needs.

[0058] The filament heating unit 232 is arranged in the circulation pipeline 223, which is opened or closed synchronously with the third valve 226. As long as the third valve 226 is opened, the filament heating unit 232 starts to operate to heat the air. Driven by the first fan 221 and the second fan 222, the heated gas and the heated gas in the shell 11 form an internal circulation airflow, so as to heat all the battery cells 12 inside the shell 11 and improve the thermal balance inside the shell 11.
