[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0039] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.
[0040] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0041] In a first aspect, an embodiment of the present application provides an energy management control method for a fuel cell system.
[0042] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the energy management control method of the fuel cell system of the present application. Figure 1 As shown, the energy management control method of the fuel cell system includes:
[0043] Step S10: predicting the acquired vehicle information and road condition information according to a preset neural network model to obtain the energy consumption value of the whole vehicle;
[0044] Exemplarily, vehicle information and road condition information are obtained, the vehicle information includes average vehicle speed and vehicle load, and the road condition information includes distance, normal road condition and abnormal road condition. The vehicle information and road condition information are input into a preset neural network model, and the preset neural network model is used to make a prediction based on the input vehicle information and road condition information to obtain a corresponding vehicle energy consumption value. The preset neural network model is obtained by training the neural network with the training data.
[0045] Step S20: According to the energy consumption value of the whole vehicle and the preset duration, the fuel cell system generates corresponding output power to the motor.
[0046] Exemplarily, the duration input by the user is obtained, or the duration is obtained according to the average speed in the vehicle information and the distance in the road condition information, and the obtained duration is used as the preset duration. The output power required by the vehicle is calculated based on the energy consumption value of the whole vehicle and the preset duration, so that the fuel cell generates the corresponding output power to the motor.
[0047] Specifically, the method of enabling the fuel cell system to generate corresponding output power to the motor based on the energy consumption value of the whole vehicle and the preset duration includes: calculating the average power required for the vehicle based on a preset formula, the energy consumption value of the whole vehicle and the preset duration; and generating corresponding output power to the motor based on the average power required for the vehicle through the fuel cell system.
[0048] For example, get the preset formula Among them, P is the output power, Q is the energy consumption value of the whole vehicle, and T is the preset time. The energy consumption value Q of the whole vehicle and the preset duration T are used to calculate the average power required by the vehicle. After the average power required by the vehicle is calculated, a command is generated and sent to the fuel cell system. The fuel cell system generates the corresponding output power to the motor based on the average power required by the vehicle.
[0049] Specifically, after calculating the average power required by the vehicle based on the preset formula, the whole vehicle energy consumption value and the preset duration, it also includes: comparing the average power required by the vehicle with the preset power; if the average power required by the vehicle is less than or equal to the preset power, then generating a corresponding output power to the motor based on the average power required by the vehicle through the fuel cell system.
[0050] Exemplarily, the average power required by the vehicle is compared with the preset power of the fuel cell system. If the average power required by the vehicle is less than or equal to the preset power of the fuel cell system, the fuel cell system generates a corresponding output power to the motor based on the average power required by the vehicle. For example, if the average power required by the vehicle is 100KW and the preset power of the fuel cell system is 100KW, the fuel cell system generates a corresponding output power of 100KW to the motor based on the average power required by the vehicle of 100KW. If the average power required by the vehicle is 80KW and the preset power of the fuel cell system is 100KW, the corresponding output power of 100KW is generated to the motor.
[0051] Specifically, after comparing the average power required by the vehicle with the preset power, it also includes: if the average power required by the vehicle is greater than the preset power, querying the charge of the power battery; if the charge ratio of the power battery is less than or equal to the first preset charge ratio, adjusting the preset power, and generating a corresponding output power to the motor through the fuel cell system based on the average power required by the vehicle; if the charge ratio of the power battery is greater than the first preset charge ratio and less than the second preset charge ratio, obtaining a first preset ratio; and determining the output powers of the fuel cell system and the power battery system respectively according to the first preset ratio and the average power required by the vehicle, so that the fuel cell system and the power battery system generate corresponding output powers to the motor.
[0052] Exemplarily, if the average power required by the vehicle is greater than the preset power of the fuel cell system, the charge of the power battery is queried. For example, if the average power required by the vehicle is 120KW and the preset power of the fuel cell system is 100KW, the charge of the power battery is queried. If the charge ratio of the power battery is less than or equal to the first preset charge ratio, the preset power is adjusted, and the corresponding output power is generated to the motor based on the average power required by the vehicle through the fuel cell system. For example, if the charge of the power battery is less than or equal to 40% of the first preset charge ratio, the preset power of the fuel cell system is adjusted to 120KW, and the corresponding output power is generated to the motor based on the average power required by the vehicle through the fuel cell system.
[0053] If the charge of the power battery is found to be greater than the first preset charge ratio of 40% and less than the second preset charge ratio of 70%, the first preset ratio is obtained. According to the first preset ratio and the average power required by the vehicle, the output power of the fuel cell system and the power battery system are determined respectively, so that the fuel cell system and the power battery system generate corresponding output power to the motor. For example, the output power of the fuel cell system is 100KW to the motor, and the output power of the power battery is 20KW to the motor.
[0054] In this embodiment, the obtained vehicle information and road condition information are predicted according to a preset neural network model to obtain the energy consumption value of the whole vehicle; according to the energy consumption value of the whole vehicle and the preset duration, the fuel cell system generates corresponding output power to the motor, which solves the problem that the fuel cell system is used as a range extender in the related technology, and the electricity generated by the fuel cell system first passes through the power battery and then is supplied to the motor, but it will cause the power battery to have excessive power throughput, thereby reducing the life of the power battery. The technical problem is that the electricity generated by the fuel cell system is directly delivered to the motor, which reduces the number of load changes of the fuel cell system and extends the life of the fuel cell system and the power battery.
[0055] In one embodiment, referring to Figure 2 , Figure 2 This is a flow chart of another embodiment of the energy management control method of the fuel cell system of the present application. Figure 2 As shown, the energy management control method of the fuel cell system includes:
[0056] Step S30: obtaining data to be trained, wherein any set of data in the data to be trained includes historical vehicle information, historical road condition information and energy consumption value, wherein the historical vehicle information includes historical average vehicle speed and historical vehicle load, and the historical road condition information includes historical distance, historical normal road condition and historical abnormal road condition;
[0057] Exemplarily, data to be trained is obtained, and any set of data in the data to be trained includes historical vehicle information, historical road condition information and energy consumption values, the historical vehicle information includes historical average vehicle speed and historical vehicle load, and the historical road condition information includes historical distance, historical normal road condition and historical abnormal road condition.
[0058] Step S40: training a preset neural network based on the data to be trained to generate a corresponding neural network model, and using the neural network model as a preset neural network model;
[0059] Exemplarily, the preset neural network is trained with the data to be trained, and the preset neural network can be a convolutional neural network and a recurrent neural network. The loss value or the number of training times of the neural network after training is obtained; if the number of training times reaches the preset number of times, it is determined that the neural network is in a convergence state, and a corresponding neural network model is generated, and the neural network model is used as the preset neural network model; or, if the loss value is less than or equal to the preset loss value, it is determined that the neural network is in a convergence state, and a corresponding neural network model is generated, and the neural network model is used as the preset neural network model.
[0060] Step S50: predicting the acquired vehicle information and road condition information according to a preset neural network model to obtain the energy consumption value of the whole vehicle;
[0061] Exemplarily, vehicle information and road condition information are obtained, the vehicle information includes average vehicle speed and vehicle load, and the road condition information includes distance, normal road condition and abnormal road condition. The vehicle information and road condition information are input into a preset neural network model, and the preset neural network model is used to make a prediction based on the input vehicle information and road condition information to obtain a corresponding vehicle energy consumption value.
[0062] Step S60: According to the energy consumption value of the whole vehicle and the preset duration, the fuel cell system generates corresponding output power to the motor.
[0063] Exemplarily, the duration input by the user is obtained, or the duration is obtained according to the average speed in the vehicle information and the distance in the road condition information, and the obtained duration is used as the preset duration. The output power required by the vehicle is calculated based on the energy consumption value of the whole vehicle and the preset duration, so that the fuel cell generates the corresponding output power to the motor.
[0064] In this embodiment, a neural network is trained through historical vehicle information, historical road condition information and energy consumption values to generate a neural network model to predict the energy demand of the entire vehicle during the entire driving mileage. According to the energy consumption value of the entire vehicle and the preset duration, the fuel cell system generates corresponding output power to the motor. This solves the problem in the related technology that the fuel cell system is used as a range extender, and the electricity generated by the fuel cell system first passes through the power battery and then is supplied to the motor, but this will cause the power battery to have excessive power throughput, thereby reducing the life of the power battery. The power generated by the fuel cell system is directly delivered to the motor, which reduces the number of load changes of the fuel cell system and extends the life of the fuel cell system and the power battery.
