Description

Technical Field

[0001] The present invention relates to the technical field of battery heating, and in particular to a heating system, a target battery and a vehicle. Background Art

[0002] Electric vehicles (BEV) refer to vehicles that use onboard power batteries as a power source to provide the motor with energy to drive the wheels and meet the requirements of road traffic and safety regulations. During the driving or charging process of electric vehicles, if the ambient temperature gradually decreases, the conductivity of the ions in the electrolyte in the battery decreases, causing the effective capacity of the battery to decrease significantly, thereby affecting the charging and discharging efficiency of the battery. Therefore, it needs to be heated.

[0003] At present, the commonly used method of heating batteries is to add additional heating equipment to the batteries, for example, directly attach a heating film around the batteries. When charging, the ambient temperature of the batteries is detected to determine whether the batteries are in a low temperature environment. If they are in a low temperature environment, the heating circuit relay is controlled to be turned on to avoid the degradation of the electrical performance of the batteries.

[0004] However, the above method often relies on the battery to discharge to heat the heating device. However, in cold weather, the battery itself cannot discharge, so the battery cannot be heated, resulting in the battery not being able to work properly.

[0005] Therefore, how to heat the battery conveniently and effectively has become a problem to be solved urgently. Summary of the invention

[0006] In view of this, the present invention provides a heating system, a target battery and a vehicle to solve the problem of how to conveniently and effectively heat the battery.

[0007] In a first aspect, the present invention provides a heating system, the heating system comprising: a heating device and a charging device, the charging device being communicatively connected with the heating device; wherein:

[0008] The charging device is used to obtain the current battery temperature of the target battery after the target vehicle is connected to the heating system; supply power to the heating device according to the current battery temperature of the target battery, and control the heating device to heat the target battery;

[0009] The heating device is used to heat the target battery under the control of the charging device.

[0010] The embodiment of the present application provides a heating system and a charging device, which are used to obtain the current battery temperature of the target battery after the target vehicle is connected to the heating system, thereby ensuring the accuracy of the current battery temperature of the target battery. The heating device is powered according to the current battery temperature of the target battery, and the heating device is controlled to heat the target battery. There is no need to rely on the discharge of the target battery to heat the target battery. Therefore, there will be no situation where the target battery cannot be discharged due to too low a temperature, and thus the target battery cannot be heated. The heating device is used to heat the target battery under the control of the charging device. The above-mentioned heating system realizes effective heating of the target battery, improves the wide application of the above-mentioned heating system, and improves the user utilization rate. In addition, the heating device is designed independently from the whole vehicle. When designing the water tank of the whole vehicle, there is no need to consider the capacity of the internal heating structure of the target battery, thereby reducing the space occupied by the water tank in the whole vehicle.

[0011] In an optional implementation, the charging device includes an electronic device and a charging interface, and the electronic device is communicatively connected to a battery management system corresponding to the target battery, wherein:

[0012] An electronic device, used to detect whether the charging device is connected to the target battery based on the charging interface; if the charging device is connected to the target battery based on the charging interface, obtaining the current remaining power and current battery temperature of the target battery sent by the battery management system;

[0013] If the current remaining power is lower than the preset power threshold, the charging device is controlled to charge the target battery;

[0014] and / or,

[0015] If the current battery temperature is lower than the preset temperature threshold, the charging device is controlled to supply power to the heating device so that the heating device heats the target battery.

[0016] The embodiment of the present application provides a heating system, an electronic device, for detecting whether the charging device is connected to the target battery based on the charging interface, thereby ensuring the accuracy of the detection result obtained.

Then, if the current remaining power is lower than the preset power threshold, the charging device is controlled to charge the target battery, so that the target battery can be charged when the current remaining power is lower than the preset power threshold, and / or, if the current battery temperature is lower than the preset temperature threshold, the charging device is controlled to power the heating device so that the heating device heats the target battery, so that the target battery can be heated when the current battery temperature is lower than the preset temperature threshold. In the above heating system, heating and charging of the target battery can be performed simultaneously or separately, thereby improving the wide use of the heating system and improving the user utilization rate. In addition, the heating device is integrated into the heating system, and the capacity of the internal heating structure of the target battery does not need to be considered when designing the water tank of the whole vehicle, which reduces the space occupied by the water tank of the whole vehicle. Finally, the number of charging systems configured is far less than the number of vehicles, so the utilization rate of the heating equipment integrated into the heating system will be higher than that on the whole vehicle. The cost saved by reducing the specifications of the heating system on the whole vehicle is far greater than the increased cost of configuring the heating equipment in the heating system, which reduces the overall cost.

[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0060] Electric vehicles (BEV) refer to vehicles that use onboard power batteries as a power source to provide the motor with energy to drive the wheels and meet the requirements of road traffic and safety regulations. During the driving or charging process of electric vehicles, if the ambient temperature gradually decreases, the electrolyte in the battery will gradually solidify, causing the effective capacity of the battery to drop significantly, thereby affecting the charging and discharging efficiency of the battery. Therefore, it needs to be heated.

[0061] At present, the commonly used method of heating batteries is to add additional heating equipment to the battery. For example, in the first solution, traditional battery systems are mostly square shell batteries. Generally, the battery module adopts the method of sticking heating film on the side or bottom surface to start heating in a low temperature environment, so as to quickly heat the battery pack to a temperature range suitable for working. The disadvantage of this solution is that the heating film is integrated in a single module, which increases a small amount of cost, and if there is a problem with the heating film, there is a certain risk in the battery pack. In the second solution, square shell and cylindrical battery packs, it is also common to heat the battery by heating the air in the battery pack by integrating the whole package. This solution increases the pipeline layout of the whole vehicle, and the whole vehicle will increase components such as water pumps. The water tank takes up more space and the whole vehicle has many parts. The third solution is that the common module frame of soft pack batteries is a solution for heating the battery pole ear. This solution will also have a layout of circulation pipelines, water pumps, and water tanks in the whole vehicle, with many components, and if the pipelines in the box are not plugged in place, there is also a risk of liquid leakage.

[0062] However, the power supply for the heating circuit of the above schemes is all taken from the battery pack, so they have common disadvantages: the vehicle cannot be operated during maintenance, which reduces the vehicle's efficiency and has a high maintenance time cost; in extremely cold conditions below -20℃ or -30℃, the lithium battery system is protected and cannot be discharged, and the heating function cannot be realized.

[0063] Therefore, how to heat the battery conveniently and effectively has become a problem to be solved urgently.

[0064] Based on the above content, the embodiment of the present application provides a heating system, such as Figure 1 As shown, the heating system includes: a heating device and a charging device, and the charging device is communicatively connected with the heating device; wherein:

[0065] The charging device is used to obtain the current battery temperature of the target battery after the target vehicle is connected to the heating system; supply power to the heating device according to the current battery temperature of the target battery, and control the heating device to heat the target battery;

[0066] The heating device is used to heat the target battery under the control of the charging device.

[0067] Specifically, after the target vehicle is connected to the heating system, the charging device can obtain the current battery temperature corresponding to the target battery based on the communication connection with the target battery. Then, when the current battery temperature meets the preset requirements, the heating device is powered and controlled to heat the target battery.

[0068] The heating device heats the target battery under the control of the charging device when the charging device supplies power.

[0069] The embodiment of the present application provides a heating system and a charging device, which are used to obtain the current battery temperature of the target battery after the target vehicle is connected to the heating system, thereby ensuring the accuracy of the current battery temperature of the target battery. The heating device is powered according to the current battery temperature of the target battery, and the heating device is controlled to heat the target battery. There is no need to rely on the discharge of the target battery to heat the target battery. Therefore, there will be no situation where the target battery cannot be discharged due to too low a temperature, and thus the target battery cannot be heated. The heating device is used to heat the target battery under the control of the charging device. The above-mentioned heating system realizes effective heating of the target battery, improves the wide application of the above-mentioned heating system, and improves the user utilization rate. In addition, the heating device is designed independently from the whole vehicle. When designing the water tank of the whole vehicle, there is no need to consider the capacity of the internal heating structure of the target battery, thereby reducing the space occupied by the water tank in the whole vehicle.

[0070] In an optional embodiment of the present application, as Figure 2 As shown, the charging device also includes an auxiliary power supply, wherein:

[0071] An electronic device used to detect whether the charging device is connected to the target battery based on the charging interface; if the charging device is connected to the target battery based on the charging interface, control the auxiliary power supply to power the battery management system; and obtain the current remaining power and current battery temperature of the target battery sent by the battery management system.

[0072] Optionally, the electronic device can detect whether the voltage on the charging interface is within a normal working range. If the voltage is not within the working range, it is determined that the charging interface is not properly connected to the target battery; if the voltage is within the working range, it is determined that the charging device is connected to the target battery based on the charging interface.

[0073] Optionally, the electronic device can detect the current on the charging interface. If current flows through the charging interface, it is determined that the charging device is connected to the target battery based on the charging interface; if no current flows through the charging interface, it is determined that the charging device is not connected to the target battery based on the charging interface.

[0074] Optionally, the electronic device may also send a specific protocol signal (such as USB PD or BC1.2 protocol) and wait for a response from the target battery. If the target battery is properly connected, the electronic device may receive the response information from the target battery. Exemplarily, if the target battery responds to the protocol signal, the electronic device may check the charging status indication, such as an LED indicator or information on a display screen, to confirm that the charging process has begun.

[0075] The embodiment of the present application does not specifically limit the manner in which the electronic device detects whether the charging device is connected to the target battery based on the charging interface.

[0076] Specifically, if the charging device is connected to the target battery based on the charging interface, the electronic device controls the auxiliary power supply to power the battery management system of the target battery. After the battery management system is powered, the current remaining power and current battery temperature corresponding to the target battery can be detected. Then, the battery management system transmits the current remaining power and current battery temperature corresponding to the target battery to the electronic device.

[0077] In an optional embodiment of the present application, as Figure 2 As shown, the charging device includes an electronic device and a charging interface, and the electronic device is communicatively connected with a battery management system corresponding to a target battery, wherein:

[0078] An electronic device, used to detect whether the charging device is connected to the target battery based on the charging interface; if the charging device is connected to the target battery based on the charging interface, obtaining the current remaining power and current battery temperature of the target battery sent by the battery management system;

[0079] If the current remaining power is lower than the preset power threshold, the charging device is controlled to charge the target battery;

[0080] and / or,

[0081] If the current battery temperature is lower than the preset temperature threshold, the charging device is controlled to supply power to the heating device so that the heating device heats the target battery.

[0082] Specifically, after the electronic device detects that the charging device is connected to the target battery based on the charging interface and obtains the current remaining power and current battery temperature of the target battery sent by the battery management system, the electronic device can compare the current remaining power with the preset power threshold. If the current remaining power is lower than the preset power threshold, the electronic device controls the charging device to charge the target battery. And / or, the electronic device compares the current battery temperature with the preset temperature threshold, and if the current battery temperature is lower than the preset temperature threshold, controls the charging device to power the heating device so that the heating device heats the target battery.

[0083] The electronic device may receive a preset power threshold and a preset temperature threshold input by a user, or may receive a preset power threshold and a preset temperature threshold sent by other devices. The electronic device may also set a preset power threshold and a preset temperature threshold according to the usage of the target vehicle. The embodiment of the present application does not specifically limit the manner in which the electronic device obtains the preset power threshold and the preset temperature threshold.

[0084] The embodiment of the present application provides a heating system and an electronic device for detecting whether a charging device is connected to a target battery based on a charging interface, thereby ensuring the accuracy of the detection result. If the charging device is connected to the target battery based on the charging interface, the auxiliary power supply is controlled to supply power to the battery management system, so that the battery management system can send the current remaining power and current battery temperature of the target battery to the electronic device.

[0085] In addition, the electronic device is used to detect whether the charging device is connected to the target battery based on the charging interface, thereby ensuring the accuracy of the detection result obtained. If the charging device is connected to the target battery based on the charging interface, the current remaining power and the current battery temperature of the target battery sent by the battery management system are obtained, so that the target battery can be controlled to be charged and / or heated according to the current remaining power and the current battery temperature. Then, if the current remaining power is lower than the preset power threshold, the charging device is controlled to charge the target battery, so that the target battery can be charged when the current remaining power is lower than the preset power threshold. And / or, if the current battery temperature is lower than the preset temperature threshold, the charging device is controlled to power the heating device so that the heating device heats the target battery, so that the target battery can be heated when the current battery temperature is lower than the preset temperature threshold. The above-mentioned heating system can heat and charge the target battery at the same time or separately, thereby improving the wide use of the heating system and improving the user utilization rate. In addition, the heating device is integrated into the heating system, and the capacity of the internal heating structure of the target battery does not need to be considered when designing the water tank of the whole vehicle, which reduces the space occupied by the water tank of the whole vehicle. Finally, the number of charging systems configured is far less than the number of vehicles, so the utilization rate of the heating equipment integrated into the heating system will be higher than that on the whole vehicle. The cost saved by reducing the specifications of the heating system on the whole vehicle is far greater than the increased cost of configuring the heating equipment in the heating system, which reduces the overall cost.

[0086] In an optional embodiment of the present application, as Figure 3 As shown, the charging device also includes a power control component, which is communicatively connected with the electronic device, wherein:

[0087] The electronic device is further used to obtain the current power consumption rate, estimated charging time, and battery capacity, maximum allowed charging power, maximum allowed charging current, and maximum allowed charging voltage corresponding to the target vehicle, and input the current remaining power, current battery temperature, current power consumption rate, estimated charging time, battery capacity, maximum allowed charging power, maximum allowed charging current, and maximum allowed charging voltage into a charging power calculation model, and the charging power calculation model outputs a target charging power corresponding to the target battery;

[0088] The electronic device is also used to control the charging device to charge the target battery based on the target charging power through the power control component.

[0089] Specifically, the electronic device may also receive the current power consumption rate corresponding to the target vehicle and the battery capacity corresponding to the target battery sent by the battery management system corresponding to the target battery, wherein the current power consumption rate refers to the power consumption per unit time of the target vehicle in the current state.

[0090] The electronic device can determine the maximum allowable charging power, the maximum allowable charging current, and the maximum allowable charging voltage corresponding to the target battery according to the attribute information corresponding to the target vehicle.

[0091] The electronic device may receive an estimated charging time input by a user.

[0092] Then, the electronic device inputs the current remaining power, current battery temperature, current power consumption rate, expected charging time, battery capacity, maximum allowed charging power, maximum allowed charging current, and maximum allowed charging voltage into the charging power calculation model. The charging power calculation model extracts features of the current remaining power, current battery temperature, current power consumption rate, expected charging time, battery capacity, maximum allowed charging power, maximum allowed charging current, and maximum allowed charging voltage, and outputs the target charging power corresponding to the target battery.

[0093] Among them, the charging power calculation model can be trained according to the training data.

[0094] The embodiment of the present application provides a heating system, an electronic device, and is also used to obtain the current power consumption rate, estimated charging time, and battery capacity, maximum allowed charging power, maximum allowed charging current, and maximum allowed charging voltage corresponding to the target vehicle and the target battery; the current remaining power, current battery temperature, current power consumption rate, estimated charging time, battery capacity, maximum allowed charging power, maximum allowed charging current, and maximum allowed charging voltage are input into a charging power calculation model, and the charging power calculation model outputs a target charging power corresponding to the target battery. It is ensured that the output target charging power not only meets the user's demand for the estimated charging time, but also ensures the safety of the target battery. The electronic device is also used to control the charging device to charge the target battery based on the target charging power through a power control component, so that the target battery can be fully charged within a preset charging time while meeting the safety of the target battery.

[0095] In an optional embodiment of the present application, as Figure 4 As shown, the heating device includes a heating medium container, a first circulation pipeline, and a heating component, wherein:

[0096] A heating medium container, used for placing a heating medium;

[0097] The input end of the heating medium container is connected to one end of the first sub-pipeline in the first circulation pipeline;

[0098] The other end of the first sub-pipe in the first circulation pipe is connected to one end of the second circulation pipe in the target battery through the first plug interface;

[0099] One end of the second sub-pipe in the first circulation pipe is connected to the output end of the heating medium container, and the other end is connected to the other end of the second circulation pipe in the target battery through the second plug interface;

[0100] The heating component is installed below the first circulation pipeline.

[0101] Specifically, the heating medium container is used to place the heating medium. The heating medium container may be a constant temperature container. The input end of the heating medium container is connected to one end of the first sub-pipeline in the first circulation pipeline. The other end of the first sub-pipeline in the first circulation pipeline is connected to one end of the second circulation pipeline in the target battery through the first plug interface. One end of the second sub-pipeline in the first circulation pipeline is connected to the output end of the heating medium container, and the other end is connected to the other end of the second circulation pipeline in the target battery through the second plug interface.

[0105] In an optional embodiment, the heating component is connected to a charging device, and the electronic device is used to control the charging device to supply power to the heating component if the current battery temperature is lower than a preset temperature threshold;

[0106] The heating component is used to heat the heating medium in the first circulation pipe, so that the heated heating medium circulates in the first circulation pipe and the second circulation pipe to heat the target battery.

[0107] Specifically, after the electronic device compares the current battery temperature with the preset temperature threshold and determines that the current battery temperature is lower than the preset temperature threshold, the electronic device can control the charging device to power the heating component. Then, after power is supplied, the heating component heats the heating medium in the first circulation pipe above the heating component.

[0115] The electronic device is used to supply power to the circulation pump when the current liquid level is lower than the first preset liquid level threshold value, so as to ensure the circulation of the heating medium in the first circulation pipeline.

[0116] Specifically, the liquid level sensor can detect the current liquid level corresponding to the heating medium in the heating medium container, and transmit the current liquid level to the electronic device.

Therefore, when the current liquid level is lower than the first preset liquid level threshold, the heating medium is added to the heating medium container, avoiding too little heating medium and burning the heating equipment.
