Problems solved by technology

The current methanol-lithium battery series hybrid power is used to drive the car, and the combination of the relatively mature planetary wheel power distribution device, methanol reforming gas device and lithium battery power supply device has made great progress, but the long-term use of methanol The engine will also generate a large amount of exhaust heat. How to use this waste heat and add an exhaust heat recovery system on this basis to achieve the purpose of further saving non-renewable energy and protecting the environment is a problem worth challenging

Embodiment Construction

[0014] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] Such as figure 1 Shown:

[0016] The relatively mature lithium battery 2 power supply device in the electric vehicle market is used to provide power for the small working conditions of the car on the one hand; on the other hand, it provides heat for the methanol gas reforming device, and uses the temperature sensor installed in the gas reforming device 8 to monitor the device. Temperature monitoring, sensors 14, 15 transmit signals to the controller 1, when the temperature in the reformed gas device 8 exceeds the upper-line temperature of the reaction, the controller 1 sends a signal to stop the lithium battery pack 2 from heating the reformed...

Abstract

The invention discloses an exhaust waste heat returning system of a lithium methoxide battery series-parallel type hybrid electric vehicle. The exhaust waste heat returning system is arranged on the lithium methoxide battery series-parallel type hybrid electric vehicle so as to recycle the tail gas waste heat of a methanol engine. The methanol engine connected with a gas path of a methanol reformed gas device (8) and a lithium battery (2) provide power for the hybrid electric vehicle, and the methanol reformed gas device (8) is provided with an electric heater (9). The exhaust waste heat returning system is characterized in that the power exhaust waste heat returning system is composed of a controller, a valve system, corresponding pipelines and a temperature sensor, wherein the valve system and the corresponding pipelines are controlled by the controller, and the temperature sensor provides temperature information for the controller (1); a tail gas opening of the engine (5) is connected with a gas inlet end gas path of a first reversing valve (4); and the gas outlet end of the first reversing valve (4) is provided with three branches, namely, a first branch emptied through a silencer (11), a second branch for heating an outer cavity of the lithium battery (2) and a third branch for providing auxiliary heat for the methanol reformed gas device (8). According to the tail gas heat recycling system, exhaust waste heat can be fully utilized so that the aims of saving non-renewable energy resources and protecting the environment can be achieved, and the system is suitable for various loaded hybrid electric vehicles.

Description

technical field [0001] The invention relates to a hybrid electric vehicle, in particular to the technical field of an exhaust waste heat utilization device of a methanol-lithium battery parallel-connected hybrid electric vehicle. Background technique [0002] As the main energy used by automobiles at present, gasoline and diesel are petroleum products. On the one hand, automobile exhaust has a greater impact on the environment; on the other hand, petroleum resources are non-renewable energy sources and are facing depletion. According to relevant information, the proven oil resources can only be exploited for more than 40 years at the current speed, and natural gas can only be exploited for more than 60 years. Therefore, there is an urgent need for automobiles to find alternative energy sources while reducing environmental pollution. [0003] As the main energy vehicle in the 21st century, electric vehicles are favored by the industry because electric energy belongs to secon...
