Clutch between part and driving motor M disconnects, and fuel cell pack stops working, and is individually for canoe by super capacitor and provides the energy.
When underpower needed for moving backward, fuel cell pack or super capacitor or fuel cell pack provide energy with super capacitor jointly
Source.When voltage value of the super-capacitor voltage value lower than setting, super capacitor stops working.
When fuel cell pack breaks down or runs out of gas, switch K1, K4 closure, switch K2, K3 are disconnected, and start diesel oil
Generating set provides the electric energy that makes a return voyage for canoe.
The output end voltage of selected unidirectional DC/DC converter is 380V in this example, and it is 370V that super capacitor, which expires piezoelectric voltage,
Power of the canoe needed for boost phase is 40kw, and fuel cell pack rated power is 20kw, and the capacity of diesel generating set is set
Meter need to meet when fuel cell breaks down, and so that yacht is maked a return voyage safely under economy navigation, while to super capacitor
Charging, revolution speed of propeller is about the 50%~70% of maximum speed when canoe is in economic navigation, selected diesel-driven generator power
For 12kw.
The embodiment of the present invention is described in attached drawing, but the invention is not limited to above-mentioned specific embodiment parties
Formula, the above mentioned embodiment is only schematical, rather than restrictive, and those skilled in the art are in this hair
Under bright enlightenment, without breaking away from the scope protected by the purposes and claims of the present invention, many forms can be also made, this
It is belonged within protection of the invention a bit.
