Title:

HYBRID POWER VEHICLE

Document Type and Number:

WIPO Patent Application WO/2015/176571

Kind Code:

A1

Abstract:

A hybrid power vehicle comprises a power battery (50), a fuel storage tank (10), a power generation unit (40), a pressure detection unit (20) and a working mode controller (30), and adopts a pressure protection mode under the working mode controller (30). The working mode controller (30) is configured to control the vehicle to enter the pressure protection mode under the condition that the power generation unit (40) is in a halt state when the gas pressure detected by the pressure detection unit (20) is higher than a pressure threshold. In the pressure protection mode, the power generation unit (40) is started from the halt state to enter the working state to consume fuel in the fuel storage tank (10), and the gas pressure in the fuel storage tank (10) is accordingly reduced. Due to the adoption of the pressure protection mode, the power generation unit (40) can be automatically started according to the gas pressure of the fuel in the fuel storage tank (10), and the power battery (50) is charged by expanded redundant fuel. Therefore, the safety and waste problems in the prior art caused by the fact that expanded fuel, the pressure of which exceeds the threshold, in the fuel storage tank (10) is discharged into the atmosphere are solved.
