The threshold relationship diagram is shown in fig. 2, wherein T1< T2< T3< T4, P1< P2< P3< P4< P5, and SOC1< SOC2< SOC3< SOC 4. T1, T2, T3, T4, P1, P2, P3, P4, P5, SOC1, SOC2, SOC3, SOC4 are preset values, and may be obtained empirically or from test data. Wherein, the SOC is set according to the system parameter setting value based on considering the user experience.
The method is integrated into a control system as a software program, and comprises the following units, as shown in fig. 3:
a power battery temperature acquisition and judgment unit: acquiring the temperature T of the power battery, and judging the temperature T of the power battery;
the first control processing unit is used for controlling the power battery not to allow continuous charging and controlling the fuel battery not to start if the temperature T of the power battery is less than or equal to a first temperature threshold T1 or the temperature T of the power battery is greater than or equal to a fourth temperature threshold T4;
the second control processing unit is used for controlling the power battery to allow low-power continuous charging and controlling the power P of the fuel battery to be less than or equal to the first power threshold P1 and the SOC of the power battery to be less than the second SOC threshold SOC2 if the temperature T of the power battery is greater than the first temperature threshold T1 and less than or equal to the second temperature threshold T2;

The power battery equipped in the fuel cell system can be a power type power battery, an energy type power battery, and the like.
According to the energy management control method, the temperature and the SOC of the power battery need to be judged in real time, the allowable power of the power battery is different in different temperature intervals, and particularly attention is paid to a high-temperature area and a low-temperature area; the SOC of the power battery is prevented from being in a high interval for a long time as much as possible, and the SOC interval is controlled to be about 50%, so that the service life of the power battery system is prolonged.
The continuous high-power charging of the power battery in a low-temperature region can cause lithium precipitation of the power battery, and the continuous high-power charging in a high-temperature region can cause the power battery to have the risk of over-temperature or thermal runaway, so that the control on the high-temperature and low-temperature regions is favorable for improving the safety of the power battery.
If the fuel cell system can output lower power and the service life of the fuel cell system is not influenced, the energy can be provided for heating the power cell in a low-temperature area, but the output power of the fuel cell is required to be less than or equal to the power required by heating the power cell.
The fuel cell system can carry out parameter calibration according to the characteristics of the fuel cell system when variable load or high-power operation is required, and can be carried out within the maximum continuous power range allowed by the power cell.
When the vehicle performs brake feedback, the current fuel cell power needs to be judged, and the possible continuous electricity return is preprocessed.
The overall design principle of the fuel cell energy management control method comprises the following steps:
1. after the vehicle is normally started, the temperature of the power battery is pre-judged, and whether a fuel cell system is normally started or power limitation starting is judged according to the current temperature interval of the power battery; and if the power battery temperature T is between the power battery minimum temperature threshold Tmin and the maximum temperature threshold Tmax, entering a fuel battery starting process, wherein Tmin < T1< T2< T3< T4< Tmax.
2. According to different temperatures of the power battery, after entering a fuel battery starting process, the fuel battery performs distributed power output by combining the current SOC of the power battery;
3. when the power battery has high temperature and high SOC, the fuel battery limits the output power or stops the power supply;
4. and when the temperature of the power battery is recovered to be normal or the SOC is reduced to be capable of starting the fuel battery system, starting the fuel battery system.
The control method mainly designs energy management of a fuel cell system and a power cell system under the condition of hybrid power output. When the power output of the fuel cell is controlled, the power output is required to be combined with the allowable continuous charging power of the power cell at different SOC and temperature. The power battery allows different continuous charging powers at different temperatures, so that the situation that the fuel battery continuously charges the power battery under the condition that the vehicle runs under no power or low power needs to be considered when the fuel battery actually controls the power output, and the allowable charging power of the power battery needs to be referred.
The scheme adopted by the control method of the invention is shown in figure 4 and comprises the following steps:
the method comprises the following steps: after the fuel cell vehicle is normally started, the vehicle controller judges whether the fuel cell is normally started or started with low power according to the current power cell temperature;
step two: and judging the starting condition of the fuel cell by referring to the temperature and the SOC of the power cell:
1. when T is less than or equal to T1 or T is more than or equal to T4, the power battery is not allowed to be charged continuously, and the fuel battery is not started to work or shut down;
2. when T is more than T1 and less than T2, T is more than T3 and less than T4, the power battery allows low-power continuous charging, the limited power P of the fuel battery is more than or equal to P1 and SOC is less than SOC2, and the power P of the fuel battery is more than or equal to P2 and SOC is less than SOC 3;
3. when T2< TBAT 3< T3, the power battery allows wide-range continuous charging power, and the power P3 is not less than P4;
step three: the normal power output of the fuel cell refers to the SOC change of the power cell:
1. when T2 is more than T and less than T3, the fuel cell outputs power in a wide range, and the control is carried out according to the SOC range of the power cell;
2. when the SOC is more than or equal to the SOC5, the fuel cell is not started or the fuel cell is shut down;
3. when the SOC5 is more than the SOC4, the power P of the fuel cell is less than or equal to P3;
4. when SOC1 is more than or equal to SOC4, P4 is more than or equal to fuel cell power and less than P5, in the interval of SOC1 and SOC4 according to the value of the current actual SOC, the power value in the interval from P4 to P5 is loaded and changed according to the set SOC allowable power range, the power corresponding to the fuel cell can be set according to different SOC interval ranges, the power is carried out by referring to the value corresponding to the horizontal and vertical coordinates, and SOC1 to SOC4 can be set according to the power allowed by the power cell;
5. when the SOC is less than or equal to the SOC1, the SOC is lower than the SOC1 according to the set parameter requirements, and the fuel cell can output power according to the maximum P5.
