[0037] (4) when the working condition is a non-braking working condition, the SOC of the energy storage battery is in a preset second SOC range, and the comparison result indicates that the whole vehicle demand power is less than the fuel cell minimum power, obtaining a correspondence between the SOC and the fuel cell power generation power; wherein in the correspondence between the SOC and the fuel cell power generation power, the greater the SOC corresponds to the smaller fuel cell power generation power;
[0038] (5) when the SOC of the energy storage battery exists in the correspondence between the SOC and the fuel cell power generation power, controlling the fuel cell to emit second electric energy according to the fuel cell power generation power corresponding to the SOC of the energy storage battery to supply power to the articulated train, wherein the rest of the second electric energy except the electric energy satisfying the whole vehicle demand power of the articulated train is transmitted to the energy storage battery to charge the energy storage battery;

[0066] In the braking condition, according to the fuel cell control strategy matched with the working condition of the articulated train and the SOC of the energy storage battery, the fuel cell is controlled to supply the articulated train with electric energy, which further includes the following specific steps (11) to (14):
[0067] (11) When the working condition is the braking condition and the SOC of the energy storage battery is in a preset fifth SOC range, the fuel cell is controlled to supply the vehicle auxiliary system of the articulated train with fourth electric energy according to the minimum power of the fuel cell, and the energy storage battery is charged with the electric energy recovered in the braking condition;
[0068] (12) In the process of charging the energy storage battery with the electric energy recovered in the braking condition, the electric energy recovered in the braking condition is monitored, and when it is determined that the electric energy recovered in the braking condition reaches an electric energy threshold, the process of charging the energy storage battery with the electric energy recovered in the braking condition is stopped and air braking is started.
[0069] (13) when the working condition is the braking working condition and the SOC of the energy storage battery is in the preset fourth SOC range, stopping the power supply operation of the fuel cell and charging the energy storage battery with the electric energy recovered in the braking working condition and supplying power to the vehicle auxiliary system of the articulated train;

[0076] For example: the whole vehicle demand power is P, the minimum power of the fuel cell is 30kW, and the maximum power is 200kW, so the SOC of the energy storage battery and the whole vehicle demand power are as shown in Table 1:
[0077] Table 1
[0078]
[0079] The rail transit vehicle powered by the pantograph, the current collector and the energy storage battery works by consuming the electric energy of the substation or the transformer substation, and the main source of the electric energy is still thermal power generation, which produces harmful substances such as carbon dioxide during the power generation process. In addition, for the vehicle with the pantograph or the third rail current collector, during the peak period of vehicle operation, too much electric energy is fed back due to electric braking, and the excess electric energy cannot be fully fed back to the power grid for recycling, so brake resistors are needed to consume the excess electric energy, resulting in resource waste. The fuel cell and energy storage battery hybrid articulated vehicle can basically absorb the electric braking electric energy during vehicle braking, reducing the waste of electric energy.
[0080] The fuel cell and energy storage battery hybrid articulated vehicle is a new energy rail transit vehicle, which only consumes hydrogen and oxygen during operation and does not discharge any harmful gas, thereby greatly reducing the emission of harmful gases such as carbon dioxide and helping to achieve the "carbon peak" and "carbon neutral" goals of the country.
[0081] A reasonable control strategy can improve the traction and braking performance of the vehicle under the existing conditions of the vehicle and improve the utilization rate of energy.
[0082] To sum up, the embodiment provides an articulated train energy control method, which controls the fuel cell to supply power to the articulated train according to the fuel cell control strategy matched with the working condition of the articulated train and the SOC of the energy storage battery, compared with the way that the energy generated by the fuel cell during the driving of the articulated train cannot be reasonably controlled in the related art, the traction and braking performance of the articulated train is met within the limited space and cost range of the vehicle according to the above-mentioned fuel cell control strategy, so that the performance of the articulated train meets the standard requirements, and the utilization rate of energy is improved and the energy consumption is reduced.
