Description

Technical Field

[0001] This application relates to the field of power supply technology, and more specifically, to a startup power supply. Background Technology

[0002] In related technologies, the performance of a starting power supply in low-temperature environments can be ensured by using an insulating outer shell material or adding a heat insulation layer. However, neither insulating outer shell materials nor heat insulation layers can alleviate the impact of low temperatures on the starting power supply to a certain extent, and they are insufficient to meet the usage requirements of starting power supplies in low-temperature environments. Summary of the Invention

[0003] This application provides a startup power supply, which can solve at least one of the above-mentioned technical problems.

[0004] This application provides a starting power supply, comprising: a battery module; a temperature detection circuit for detecting the temperature of the battery module to obtain a monitoring temperature; a heating circuit for heating the battery module; and a controller connected to the temperature detection circuit and the heating circuit respectively, for controlling the operating condition of the heating circuit based on the monitoring temperature, so that the monitoring temperature of the battery module is within a preset temperature range.

[0005] The starting power supply of this application includes a battery module, a temperature detection circuit, a heating circuit, and a controller. The temperature detection circuit detects the temperature of the battery module to obtain a monitored temperature. The heating circuit heats the battery module. The controller is connected to both the temperature detection circuit and the heating circuit and controls the operation of the heating circuit based on the monitored temperature to ensure that the monitored temperature of the battery module is within a preset temperature range. Since the battery module's internal structure and chemical composition are damaged when operating outside the preset temperature range, shortening its lifespan, the temperature detection circuit monitors the battery module's temperature in real time to obtain a monitored temperature. The controller then controls the operation of the heating circuit based on this monitored temperature, allowing for timely heating of the battery module and maintaining its monitored temperature within the preset temperature range. This improves the starting power supply's activity and output power, ensures smooth startup in low-temperature environments, enhances its low-temperature startup performance and reliability, and extends its lifespan.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0010] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one feature. In the description of this application, "multiple" means at least two, such as two or three, unless otherwise explicitly specified.

[0012] The starting power supply provided in this application embodiment provides a powerful current to the vehicle's starter motor at the moment of vehicle startup. When the vehicle starts, the starter motor needs high power to drive the engine, and the starting power supply can stably output high current to ensure the vehicle starts smoothly.

[0013] The starting power supply provided in this application embodiment can use various battery types, such as lead-acid batteries and lithium-ion batteries. Taking a sodium-ion battery as an example, the charging and discharging of the sodium-ion battery is achieved through the movement of sodium ions between the positive and negative electrodes (i.e., the chemical reaction of sodium ions).

[0014] The applicant discovered that temperature has a significant impact on battery chemical reactions. For example, in low-temperature environments, the activity of sodium ions decreases, the rate of chemical reactions inside the battery slows down, leading to increased internal resistance, reduced battery capacity and charge / discharge efficiency, and even the inability of the starting power supply to power on. Similarly, starting power supplies for lead-acid and lithium-ion batteries also have similar problems. Low temperatures increase the viscosity of the electrolyte in lead-acid batteries, slowing down ion diffusion; low temperatures also hinder the insertion and extraction of lithium ions in the electrode materials, affecting battery performance.

[0015] To address the aforementioned technical problems, this application provides a startup power supply 10. Please refer to [link to relevant documentation]. Figure 2 The starting power supply 10 can be used in vehicles and is electrically connected to the vehicle's power battery 20.

[0016] Optionally, the battery module 11 includes a rechargeable battery and / or a supercapacitor.

[0017] The rechargeable battery includes at least one of sodium batteries, lithium batteries, and lead-acid batteries.

[0018] For example, a rechargeable battery may include a sodium battery; or, a rechargeable battery may include a sodium battery and a lead-acid battery; or, a rechargeable battery may include a sodium battery, a lithium battery, and a lead-acid battery. This application does not limit the scope of these categories and they are not listed here.

[0019] Rechargeable batteries include sodium batteries, lithium batteries, or lead-acid batteries; supercapacitors are also known as supercapacitors, electrochemical capacitors, electrical double-layer capacitors, gold capacitors, farad capacitors, etc. Both rechargeable batteries and supercapacitors can be used to store electrical energy to enable the charging and discharging of power supplies.

[0020] The monitored temperature can be the current temperature of the battery module 11.

[0021] The preset temperature range can be the operating temperature range of the battery module 11. When the battery module 11 is charged and discharged within the preset temperature range, the charging and discharging performance of the battery module 11 can be guaranteed.

[0022] Optionally, the starting power supply 10 may include an emergency starting power supply.

[0023] A starting power supply can store electrical energy and can be used in vehicles to power the vehicle's engine and electrical system. It can generate enough current to start the vehicle's engine and generator in a short time. It can also be used in agricultural machinery, ships, and other similar applications.

[0024] Emergency jump starters can provide power to vehicles, agricultural machinery, ships, and other vehicles that cannot start due to insufficient battery power.

[0025] The battery module 11 can be used to store and release electrical energy, providing power to the starter motor when the vehicle starts. The battery module 11 can use various types of batteries, such as lead-acid batteries, lithium-ion batteries, or sodium-ion batteries.

[0026] The controller 14 may include a microcontroller unit (MCU) or a digital signal processor (DSP). An MCU is a microcomputer chip that integrates a central processing unit (CPU), memory, input / output (I / O) interfaces, and other functions; it is a controller used for digital signal processing. Furthermore, the controller 14 may also include a purely hardware circuit composed of multiple electronic components, or it may include a circuit composed of a microcontroller unit and multiple electronic components. These electronic components may include one or more devices such as resistors, capacitors, comparators, amplifiers, and MOSFETs.

[0027] Optionally, the temperature detection circuit 12 includes at least one of an infrared temperature sensor and a thermistor.

[0028] For example, the temperature detection circuit 12 may include an infrared temperature sensor; or, the temperature detection circuit 12 may also include a thermistor; or, the temperature detection circuit 12 may also include an infrared temperature sensor and a thermistor.

[0029] For example, taking the temperature detection circuit 12, which includes an infrared temperature sensor, as an example, the battery module 11 can radiate infrared rays, and the radiation intensity is closely related to the temperature of the battery module 11. The higher the temperature, the stronger the emitted infrared energy. The infrared temperature sensor can respond to the temperature of the battery module 11 and send a corresponding temperature signal to the controller 14.

[0030] For example, taking the temperature detection circuit 12 including a thermistor as an example, the thermistor may include a positive temperature coefficient thermistor (PTC) or a negative temperature coefficient thermistor (NTC). The resistance value of the thermistor can change with temperature, resulting in different voltage drops presented by the thermistor. Based on the corresponding voltage drop signal, the temperature of the battery module 11 can be determined.

[0031] Optionally, the heating circuit 13 is disposed along at least one outer surface of the battery module 11, and / or the heating circuit 13 is disposed close to the battery module 11.

[0032] The heating circuit 13 can be disposed along at least one outer surface of the battery module 11. For example, the heating circuit 13 can wrap around the outer surface of the battery module 11; or, the heating circuit 13 can be disposed close to the battery module 11 to increase the temperature of the battery module 11 through thermal radiation.

[0033] Optionally, the heating circuit 13 includes at least one of a heating film, a heating wire, and a heating element; The heating circuit 13 is arranged around the outer surface of the battery module 11.

[0034] The heating film converts electrical energy into heat energy. For example, the heating film can include a metal heating film and a polymer heating film. The heating film can be disposed around the outer surface of the battery module 11, and the projection of the heating film can cover the outer surface of the battery module 11. The heating film surrounding the outer surface of the battery module 11 can ensure that all parts of the battery module 11 can be in contact with heat, avoid local overheating or overcooling, reduce heat loss, and improve heating efficiency.

[0035] The heating wire can be a resistive element that operates using the heating effect of electric current. The heating element can be an electric heating device in which a resistive heating wire is wound around a mica plate (mica sheet). The heating circuit 13 is arranged around the outer surface of the battery module 11 and can convert electrical energy into heat energy, thereby increasing the temperature of the battery module 11 through thermal radiation, heat transfer, etc.

[0036] Optionally, the power supply also includes a housing, in which the battery module 11, temperature detection circuit 12 and heating circuit 13 are all housed; The starting power supply also includes a first terminal and a second terminal, which are located in the housing and are used to connect the battery module 11 and the vehicle system. The automotive system includes at least one of a starter motor and on-board electronics, and the first and second terminals are used to enable the battery module 11 to supply power to the automotive system; The vehicle system also includes a generator, and the first and second terminals are used to receive power from the vehicle system to enable the vehicle system to charge the battery module 11.

[0037] The battery module 11 may include a first terminal (such as...) Figure 2 As shown, the first pole can be pole P+) and the second pole (e.g. Figure 2 As shown, the second terminal can be a terminal P-), the first terminal and the second terminal are located on both sides of the battery module 11, and the battery module 11 can be electrically connected to an external automotive system through the first terminal and the second terminal. For example, please refer to... Figure 2 The battery module 11 is electrically connected to the vehicle system's power battery 20 via a first terminal P+ and a second terminal P-. The vehicle system includes at least one of a starter motor and on-board electronic devices. For example, when the vehicle is starting, the battery module 11 provides electrical energy to the vehicle system via the first and second terminals to control the vehicle's start-stop function; furthermore, when the vehicle is in motion, the battery module 11 can also receive electrical energy from the vehicle system via the first and second terminals to charge the battery module 11.

[0038] Specifically, the power supply 10 includes a battery module 11, a temperature detection circuit 12, a heating circuit 13, and a controller 14. The temperature detection circuit 12 can be used to detect the temperature of the battery module 11 (for example, by setting a thermocouple with its measuring end close to the battery cell of the battery module 11) to obtain the monitored temperature. The heating circuit 13 can generate heat and transfer heat to the battery module 11, allowing the temperature of the battery module 11 to rise quickly, achieving the effect of heating the battery module 11. The heating circuit 13 is positioned close to the battery module 11 to ensure that heat can be efficiently and directly transferred to the battery module 11, enabling faster heating. The temperature of the battery module 11 is raised to a preset temperature range to improve charging and discharging efficiency. The controller 14 is connected to the temperature detection circuit 12 and the heating circuit 13 respectively. The controller 14 can control the operating condition of the heating circuit 13 based on the monitored temperature detected by the temperature detection circuit 12 (e.g., control the heating circuit 13 to heat or stop heating), so that the monitored temperature of the battery module 11 can be within the preset temperature range, thereby avoiding the battery module 11 from charging and discharging under low temperature or overheating conditions, improving the charging and discharging efficiency of the battery module 11, ensuring that the power supply 10 can start and run smoothly in low temperature environment, and ensuring the safety of the power supply 10.

[0039] Thus, when the battery module 11 operates in a temperature environment outside the preset temperature range, it will damage the internal structure and chemical composition of the starting power supply 10, shortening its service life. The temperature detection circuit 12 monitors the temperature of the battery module 11 in real time to obtain the monitored temperature, and the controller 14 controls the operation of the heating circuit 13 according to the monitored temperature. This allows the battery module 11 to be heated in a timely manner, keeping the monitored temperature of the battery module 11 within the preset temperature range. This improves the activity and output power of the starting power supply 10, ensures that the starting power supply 10 can start smoothly in low-temperature environments, improves the low-temperature starting performance and reliability of the starting power supply 10, and extends its service life.

[0040] Please see Figure 2 Optionally, the power supply 10 also includes: Heating switch 15 is located between battery module 11 and heating circuit 13. Heating switch 15 is used to control the operating condition of heating circuit 13.

[0041] The heating switch 15 may include at least one of a switching transistor or a relay. The heating switch 15 is located between the battery module 11 and the heating circuit 13, and the switching transistor may include at least one of a transistor or a MOSFET.

[0042] Specifically, the heating switch 15 is located between the battery module 11 and the heating circuit 13, that is, the heating switch 15 is connected in series in the circuit that supplies power to the heating circuit 13. One end of the heating switch 15 is connected to the battery module 11, and the other end of the heating switch 15 is connected to the heating circuit 13. The heating switch 15 can control the operating condition of the heating circuit 13. For example, when the heating switch 15 is closed, the electrical energy output by the battery module 11 can be transmitted to the heating circuit 13, causing the heating circuit 13 to start working; when the heating switch 15 is open, the electrical energy output by the battery module 11 cannot be transmitted to the heating circuit 13, and the heating circuit 13 stops working.

[0043] In some implementations, the controller 14 is also used to record and detect whether the power supply 10 is being started for the first time.

[0044] The initial startup can refer to the startup process when the power supply 10 is turned on again after being turned off. In other words, the initial startup can be the process of switching from a state where the power supply 10 is not activated to a state where it is activated for the first time and starts working. For example, if the controller 14 is activated again after the power supply 10 is turned off, the power supply 10 can be considered to be powered on for the first time.

[0045] Optionally, the initial startup can also be the discharge process when the power supply 10 stops discharging for a preset time and then discharges again. For example, the controller 14 can obtain the discharge timestamp of the power supply 10, and determine that the power supply 10 is starting for the first time if the time difference between the current discharge timestamp and the previous discharge timestamp is greater than the preset time.

[0046] Please see Figure 2 and Figure 3 Optionally, the operating conditions of the heating circuit 13 include heating or stopping heating, and the preset temperature range includes a first heating temperature and a first cutoff temperature, wherein the first cutoff temperature is greater than the first heating temperature. The controller 14 is used to execute: Step 011: When the power supply 10 is started for the first time, obtain the monitoring temperature of the battery module 11; Step 012: When the monitored temperature is lower than the first heating temperature, the operating mode of the heating circuit 13 is switched to heating; Step 013: When the monitored temperature reaches the first cutoff temperature, the operating condition of the heating circuit 13 is switched to stop heating.

[0047] The first heating temperature can be the power-on heating temperature of the power supply 10. It can be assumed that the power supply 10 can start when the current temperature of the battery module 11 is greater than or equal to the first heating temperature; and the power supply 10 cannot start when the current temperature of the battery module 11 is less than or equal to the first heating temperature.

[0048] The first cutoff temperature can be the start-up and stop heating temperature of the power supply 10. It can be assumed that if the monitored temperature of the battery module 11 is greater than the first cutoff temperature, the power supply 10 may be overheated and damaged if it is started.

[0049] Specifically, the operating conditions of the heating circuit 13 include heating or stopping heating. For example, when it is determined that the power supply 10 is starting for the first time, the monitoring temperature of the battery module 11 detected by the temperature detection circuit 12 can be obtained and compared with the first heating temperature. If the current temperature is lower than the first heating temperature, the power supply 10 may not be able to start normally. At this time, by switching the operating condition of the heating circuit 13 to heating, the battery module 11 can be heated so that the battery module 11 can quickly reach the temperature to adapt to the charging and discharging reaction when it is started for the first time, avoiding problems such as delayed chemical reaction of the battery module 11 or failure to start due to low temperature.

[0050] As the heating circuit 13 continues to heat up, and due to the temperature rise during the charging and discharging process of the power supply 10, the temperature of the power supply 10 continuously increases. If the current temperature exceeds the first cutoff temperature, continued heating will cause the temperature of the power supply 10 to exceed its suitable operating temperature, leading to overheating and reducing the safety of the power supply 10. Therefore, when the temperature of the battery module 11 reaches the first cutoff temperature (which can be considered as the power supply 10 being able to start normally at this point), the heating circuit 13 can be switched to stop heating, cutting off the process of converting electrical energy into heat energy. This prevents the battery module 11 from overheating and ensures that it can continue charging and discharging within a safe and stable preset temperature range.

[0051] Please see Figure 5 Optionally, the heating circuit's operating conditions include heating or stopping heating, and the preset temperature range includes a second heating temperature and a second cutoff temperature, where the second cutoff temperature is greater than the second heating temperature. The controller is used to: Step 014: When the power supply 10 is not starting for the first time, obtain the monitoring temperature of the battery module; Step 015: When the monitored temperature is lower than the second heating temperature, switch the operating mode of the heating circuit to heating. Step 016: When the monitored temperature reaches the second cutoff temperature, the operating condition of the heating circuit is switched to stop heating.

[0052] The second heating temperature and the second cutoff temperature can be set according to the suitable operating temperature of the power supply 10. The second cutoff temperature is greater than the second heating temperature. For example, the second heating temperature can be greater than or equal to the minimum temperature value of the suitable operating temperature range of the power supply 10, and the second cutoff temperature can be less than or equal to the maximum temperature value of the suitable operating temperature range of the power supply 10.

[0053] Specifically, after the power supply 10 has been turned on for a period of time, the power supply 10 can be kept warm according to the second heating temperature and the second cutoff temperature. When the monitored temperature is less than or equal to the second heating temperature, the operation of the heating circuit 13 is switched to convert electrical energy into heat energy and transfer the heat to the battery module 11 through heat conduction and other means, thereby increasing the temperature of the battery module 11. When the monitored temperature is greater than or equal to the second cutoff temperature, the heating circuit 13 is stopped to reduce the rate of temperature rise of the battery module 11, so that the current temperature of the battery module 11 is within the suitable temperature range for the operation of the power supply 10, thereby keeping the power supply 10 warm and ensuring the stable performance of the battery.

[0054] Please see Figure 5 Optionally, the battery module 11 includes one or more battery packs, and the temperature detection circuit 12 includes multiple circuits, with each battery pack having a corresponding temperature detection circuit 12. Step 011: Obtain the current temperature of the power supply 10, including: Step 0111: Determine the temperature of each battery pack based on the temperature collected by the temperature detection circuit 12 corresponding to each battery pack; Step 0112: Determine the current temperature of battery module 11 based on the temperature of each battery pack.

[0055] Specifically, the battery module 11 includes one or more battery packs, and the temperature detection circuit 12 includes multiple circuits. Each battery pack is equipped with a corresponding temperature detection circuit 12. Each temperature detection circuit 12 can collect the temperature information of its corresponding battery pack in real time and determine the current temperature of the power supply 10 based on the temperature of each battery pack. For example, given the temperatures of each battery pack, the minimum temperature can be determined as the current temperature of the power supply 10; or the average temperature can be taken as the current temperature of the power supply 10. By independently monitoring the temperature of each battery pack, the temperature distribution of the battery module can be more accurately understood. Since the reactions of different battery packs during charging and discharging may differ, by accurately understanding the temperature of each battery pack and determining the current temperature of the power supply 10, the operating state of the heating circuit 13 can be adjusted accordingly.
