[0023] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

It should be noted that in the embodiments of this application, some existing solutions in the industry such as certain software, components, and models may be mentioned, and they should be considered as exemplary. Their purpose is only to illustrate the feasibility of the implementation of the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0026] In order to solve the problems of the prior art, the embodiments of the present application provide a vehicle control method, device, storage medium, program product and vehicle. The vehicle control method provided by the embodiments of the present application is first introduced below.

[0027] Figure 1 FIG. 1 is a flow chart of a vehicle control method provided by an embodiment of the present application. Figure 1 As shown, the vehicle control method may include:

[0028] Step 101, when the vehicle is started, obtain the real-time temperature of the power battery.

[0029] In step 101, the vehicle may include an aluminum-air fuel cell and a power battery. The power battery may be a power type battery, such as a lithium-ion battery.

[0030] For example, the vehicle can use an electric-electric coupling power system of an energy-type aluminum-air fuel cell and a power-type lithium-ion battery. The theoretical energy density of aluminum-air fuel cells is as high as 8140Wh / kg, and the current actual maximum can reach 450wh / kg, which greatly improves the endurance of new energy vehicles. In conjunction with power-type lithium-ion batteries, it can achieve high endurance and high power at the same time. In addition, aluminum-air fuel cells only consume aluminum blocks, oxygen in the air, and water in the electrolyte to provide electricity when working. The aluminum electrodes can be continuously replaced to continue working, and the generated product Al2O3.nH2O can be recycled and reused. It is a high-performance, pollution-free battery with long life, high safety, and the ability to quickly replenish electricity.

[0031] It is understandable that the power battery may not work properly in a low temperature environment, or may work but with poor electrical performance. Based on this, when the vehicle is started, the temperature of the power battery can be measured in real time by a temperature sensor near the power battery to obtain the real-time temperature of the power battery.

[0032] Step 102, when the real-time temperature is less than or equal to a first temperature threshold, control the aluminum-air fuel cell to provide power for the vehicle and heat the power battery; wherein the first temperature threshold is a critical temperature value for normal operation of the power battery.

[0033] In step 102, the first temperature threshold may be a critical temperature value for the power battery to work normally. In other words, when the temperature is lower than the first temperature threshold, the power battery will not work normally. For example, if the power battery is a lithium-ion battery, the first temperature threshold may be -30°C.

[0034] If the real-time temperature is less than or equal to the first temperature threshold, it can be considered that the power battery cannot work normally, that is, it cannot provide power to the vehicle, and the vehicle will not be able to drive and operate normally. At this time, the aluminum-air fuel cell can be controlled to provide power to the vehicle.

[0035] Aluminum-air fuel cells have particularly good low-temperature performance and can work normally at -40°C. By replacing the range extender with an aluminum-air fuel cell, the vehicle can be powered in an environment where the real-time temperature is less than or equal to the first temperature threshold, allowing the vehicle to travel slowly, solving the problem of being unable to start the vehicle due to the inability to start the range extender in a low-temperature environment. Aluminum-air fuel cells generate a lot of heat when discharging, which can quickly heat up the power battery at extremely low temperatures, so that the temperature of the power battery can rise faster to a temperature at which it can work normally, speeding up the normal energy supply of the power battery.

[0036] The vehicle control method of the embodiment of the present application can obtain the real-time temperature of the power battery when the vehicle is started; when the real-time temperature is less than or equal to the first temperature threshold, the aluminum-air fuel cell is controlled to provide power to the vehicle and heat the power battery; wherein the first temperature threshold is the critical temperature value for the normal operation of the power battery. In this way, when the real-time temperature of the power battery is lower than the critical temperature value for its normal operation, the aluminum-air fuel cell can be used to provide power to the vehicle, and at this time the vehicle is traveling at a slow speed, while the aluminum-air fuel cell discharges and releases heat to heat the power battery, so that the ambient temperature of the power battery is increased, so as to speed up the normal energy supply of the power battery, make up for the many limitations brought about by the difficulty of the power battery to work normally in a low temperature environment, and improve the power performance of new energy vehicles in a low temperature environment, so as to break through the limitations of the low temperature environment and improve the applicability of new energy vehicles.

[0037] In addition, the aluminum-air fuel cell has a simple structure, is safe and environmentally friendly, and does not require an external power source for charging. Charging can be completed by replacing the aluminum plate. It can effectively solve the problems of slow charging of new energy vehicles and queuing for charging during peak hours, thereby improving the endurance of new energy vehicles and reducing users' time costs.

[0038] In some embodiments, the vehicle may further include a thermal management system; when the real-time temperature is less than or equal to the first temperature threshold, controlling the aluminum-air fuel cell to provide power to the vehicle and heating the power battery may include:

[0039] When the real-time temperature is less than or equal to the first temperature threshold, controlling the aluminum-air fuel cell to provide power for the vehicle and heat the power battery;

[0040] And control the thermal management system to heat the power battery.

[0041] In this embodiment, if the real-time temperature is less than or equal to the first temperature threshold, the aluminum-air fuel cell can be controlled to provide power for the vehicle. At this time, the aluminum-air fuel cell generates a large amount of heat during discharge, which can heat up the power battery at an extremely low temperature. At the same time, the thermal management system can also be controlled to heat the power battery so that the temperature of the power battery can rise faster to a temperature at which it can work normally, further shortening the heating time and speeding up the normal energy supply of the power battery.

[0042] In some embodiments, the method may further include:

[0043] When the real-time temperature is greater than the first temperature threshold and less than the second temperature threshold, the aluminum-air fuel cell and the power battery are controlled to provide power for the vehicle.

[0044] In this embodiment, if the real-time temperature is greater than the first temperature threshold and less than the second temperature threshold, it can be considered that the power battery can work normally, but the electrical performance of the power battery is poor and cannot provide sufficient power for the vehicle. Taking the power battery as a lithium-ion battery as an example, the second temperature threshold can be -20°C.

[0045] For example, if the temperature of the lithium-ion battery rises to -30 to -20°C, the aluminum-air fuel cell and the lithium-ion battery can jointly provide power for the vehicle, which can improve the vehicle's power to a certain extent, and there is no need to burn oil to start the range extender. At the same time, the aluminum-air fuel cell can continue to discharge and release heat to speed up the heating rate of the power battery.

[0046] In some embodiments, the method may further include:

[0047] When the real-time temperature is greater than or equal to the second temperature threshold, the power battery is controlled to provide power to the vehicle.

[0048] In this embodiment, taking the power battery as a lithium-ion battery as an example, if the real-time temperature rises to above -20°C, the electrical performance of the lithium-ion battery is restored, and the lithium-ion battery can be controlled to provide power for the vehicle.

[0049] In some embodiments, when the real-time temperature is greater than or equal to the second temperature threshold, controlling the power battery to provide power to the vehicle may include:

[0050] When the real-time temperature is greater than or equal to a second temperature threshold, controlling the power battery to provide power to the vehicle;

[0051] And control the aluminum-air fuel cell to charge the power battery.

[0052] In this embodiment, if the real-time temperature rises to above -20°C, the lithium-ion battery can be controlled to provide power for the vehicle. At the same time, the aluminum-air fuel cell can be controlled to charge the power battery.

[0053] For example, aluminum-air fuel cells can offset part of the polarization of lithium-ion batteries by charging lithium-ion batteries with a small current, slowing down the voltage drop rate of lithium-ion batteries and avoiding undervoltage problems caused by extremely rapid voltage drop in lithium-ion batteries. In particular, when lithium-ion batteries are in a low temperature and low state of charge (SOC) and need to run in harsh working conditions, undervoltage problems can be effectively improved.

[0054] In some embodiments, the aluminum-air fuel cell includes a first aluminum-air fuel cell and a second aluminum-air fuel cell;

[0055] Among them, the first aluminum-air fuel cell is used to provide power for the vehicle, and the second aluminum-air fuel cell is used to charge the power battery.

[0056] In this embodiment, the aluminum-air fuel cell may include a first aluminum-air fuel cell for providing power to the vehicle and a second aluminum-air fuel cell for charging the power battery. In other words, two aluminum-air fuel cells may be used, one aluminum-air fuel cell stores energy to replenish the lithium-ion battery, while the other aluminum-air fuel cell supplies energy to the vehicle, thereby realizing an ideal vehicle usage scenario of charging and discharging at the same time, supplying energy and replenishing energy at the same time, and improving the vehicle's power and cruising range.

[0057] In order to facilitate understanding of the vehicle control method provided by the above embodiment, the above vehicle control method is described below using a specific scenario embodiment. Figure 2 As shown, taking the power battery as a lithium-ion battery as an example, the scenario embodiment may include:

[0058] Step 201, when the temperature of the lithium-ion battery is -40 to -30°C, the aluminum-air fuel cell works independently, starts the vehicle to drive slowly, and discharges heat to increase the temperature of the lithium-ion battery;

[0059] Step 202, when the temperature of the lithium-ion battery is -40 to -30°C, after the vehicle is started, thermal management heats the lithium-ion battery;

[0060] Step 203, when the temperature of the lithium-ion battery is -30 to -20°C, the aluminum-air fuel cell and the lithium-ion battery jointly provide power for the vehicle, which improves the power of the lithium-ion battery to a certain extent, and there is no need to burn oil to start the range extender. The heat released by the discharge of the aluminum-air fuel cell also accelerates the heating speed of the lithium-ion battery;

[0061] Step 204, when the temperature of the lithium-ion battery is -20 to 60°C, the aluminum-air fuel cell offsets part of the polarization by charging the lithium-ion battery with a small current, slowing down the voltage drop rate of the lithium-ion battery, and avoiding the undervoltage problem of the lithium-ion battery due to the rapid drop in voltage.

[0062] Based on the vehicle control method provided in the above embodiment, the present application also provides an embodiment of a vehicle control device.
