Technical field

1. The utility model relates to a generator, and in particular to a flameout circuit of a generator used as a range extender.

Background technology

2. Electric vehicles have significant advantages such as high efficiency, energy saving, low noise, and zero emissions, and have unparalleled advantages in environmental protection and energy saving. However, due to the limited energy storage of batteries at present, pure electric vehicles have the problem of short driving range after one charge. In order to solve the above problem, it is usually considered to add a range extender to a pure electric vehicle to increase the driving range of the electric vehicle. The range extender usually takes the form of: small generator, battery, fuel cell, etc. Since the existing generator technology is mature and the use cost is low, the generator is a preferred solution as a range extender.

3. The generator magnet steel used as a range extender cuts the ignition coil to generate current, and the boosted spark plug ignites the compressed mixed mist gas and air in the engine cylinder to ignite the gasoline engine. When the engine needs to be turned off, the gasoline engine in the generator can be turned off by grounding the flameout wire. At present, conventional flameout is achieved by manually grounding the ignition coil, but this method cannot automatically turn off the engine according to actual conditions.

Utility Model Content

4. The purpose of the utility model is to provide a generator flameout circuit structure as an electric vehicle range extender that can automatically turn off the engine according to the situation.

5. In order to achieve the above purpose, the following technical scheme is adopted: a generator flameout circuit structure as an electric vehicle range extender, including an ignition coil connected to a high-voltage cap of the generator, and a flameout wire is connected to the ignition coil, characterized in that: the flameout wire is connected to a microprocessor, and the microprocessor is also connected to a gear control module and a battery voltage detection module through a wire.

Specific implementation

8. A generator flameout circuit structure as an electric vehicle range extender includes an ignition coil connected to a high-voltage cap of the generator, a flameout line 1 is connected to the ignition coil, and the flameout line is connected to a microprocessor. The microprocessor is also connected to a gear control module and a battery voltage detection module through a wire. Under normal circumstances, the ignition coil 2 continuously provides power to the high-voltage cap 3, and the high-voltage cap and the spark plug 4 generate electric sparks to ignite the gasoline engine inside the generator to generate electricity.

10. There are three ways to flame out. First, turn off the power supply of the microprocessor, the entire microprocessor does not work, the flameout port connected to the flameout line is in a conducting state, and the ignition coil is grounded, thereby flameout. Second, when the signal of the gear module is a pure electric gear, the microprocessor controls the flameout port to be in a conducting state and flameout. Third, when the signal of the gear module is an automatic gear, if the microprocessor detects that the battery voltage is higher than the set value, the microprocessor controls the flameout port to be in a conducting state and flameout.
