Fuel cell end voltage by boosting DC/DC converter boosting come the voltage class with system dc bus into Row matching, there is no coupled relation between the voltage and fuel battery power fan-out capability of system dc bus, the DC/DC that boosts becomes The voltage of DC bus is maintained the electrical voltage point or range of optimum electric system work by parallel operation.
Due to the presence of unilateral diode in the system, only enter superbattery so that braking and sliding feedback energy.
Based on above-mentioned hybrid power system, using control logic as shown in Figure 2.
The SOC for detecting power battery pack, judges whether the value is greater than the set value SOCc:
If the SOC of power battery pack is greater than SOCc, then boosting DC/DC converter is controlled, so that fuel cell is stopped output, i.e., Charging current I=0;
If the SOC of power battery pack is less than or equal to SOCc, then boosting DC/DC converter is controlled, makes fuel cell to power Constant-current charge, stage are divided battery pack according to power battery pack state of charge stage by stage, the charging current in each stage Difference, and the charging current in power battery pack state of charge big stage is greater than the power battery pack state of charge small stage Charging current.
The segmentation for being illustrated in figure 2 power battery pack allows charging current figure.In this embodiment, the stage 3 will be set as It is a, specific:
1) when the SOC of power battery pack is less than or equal to SOCaWhen, maximum charging current I=Ia
2) when the SOC of power battery pack is greater than SOCaAnd it is less than or equal to SOCbWhen, maximum charging current I=Ib
3) when the SOC of power battery pack is greater than SOCbAnd it is less than or equal to SOCcWhen, maximum charging current I=Ic
As shown in figure 3, setting thermostat control logic.Specifically:
1) when the SOC of power battery pack is less than or equal to SOCaWhen, thermostat control coefrficient α (t)=1;
2) when the SOC of power battery pack is greater than SOCaAnd it is less than or equal to SOCcWhen, thermostat control coefrficient α (t)=α (t- 1);
3) when the SOC of power battery pack is greater than SOCcWhen, thermostat control coefrficient α (t)=0.
I.e. are as follows:
By the setting of above-mentioned thermostatic control logic, power battery pack is carried out in the electric energy for extracting fuel battery engines Charging, charging current I of the boosting DC/DC converter to power battery packdc=I* α (t), specific function expression are as follows:
It is charged using the above method to power battery pack, simple and reliable, fuel cell is without following vehicle power Variation, it is only necessary to by the DC/DC converter constant current operation stage by stage that boosts, extend the service life of fuel cell.
For α (t), range restraint mode is really put back into, i.e. α (t) becomes 1 by 0 or becomes 0 Dou You return difference area by 1 Between, it is therefore an objective to avoid 0 and 1 concussion.
