Description

Technical Field

[0001] This application relates to the field of vehicle power supply technology, and in particular to a high-power, long-range vehicle power supply system. Background Technology

[0002] Most existing vehicle power supply systems are powered by electricity, with batteries being the primary source of power.

[0003] Battery power supply is low-voltage DC, making it difficult to power high-power AC equipment. Furthermore, battery capacity limits operating time, and battery replacement is difficult with long charging times, hindering the continuous operation of the electrical system for extended periods. Longer-range batteries are also larger, often occupying significant space and adding weight to the electrical system.

[0004] The generator produces a lot of noise and black smoke when it is running. When the vehicle vibrates, especially when moving uphill or downhill, air can enter the oil inlet due to the tilt of the oil tank level. This causes air to enter the generator oil inlet, affecting the normal operation of the generator. The generator will also have air intake problems after it has been stationary for a long time, making it difficult to ensure stable operation and easily generating a lot of dust. Utility Model Content

[0005] The purpose of this application is to provide a high-power, long-range vehicle-mounted power supply system that solves the problems of slow charging, short range, difficulty in ensuring stable operation in mobile scenarios, and dust generation caused by generator power supply in existing power supply systems.

[0006] To achieve the above objectives, this application provides a high-power, long-range vehicle-mounted power supply system, which comprises a diesel generator 1, an electronic fuel pump 2, a starter battery, and an exhaust gas purification device 4, specifically including:

[0007] The oil inlet of the diesel generator 1 is connected to the electronic oil pump 2, which is connected to the starter battery via a relay. The electronic oil pump 2 is activated by the relay each time the generator starts. The exhaust outlet of the diesel generator 1 is equipped with an exhaust gas purification device 4, which is used to purify PM particles, mainly carbon, in the exhaust gas and reduce noise.

[0008] Furthermore, the electronic oil pump 2 is linked to the relay through a control circuit. When the generator starts, the relay automatically triggers the electronic oil pump 2 to run.

[0009] Furthermore, a liquid level sensor 3 is installed inside the fuel tank to detect the fuel level in real time.

[0010] Furthermore, the liquid level sensor 3 is connected to the vehicle display terminal and is used to issue a warning signal when the fuel level is low.

[0011] Furthermore, the fuel tank is also equipped with a quick refueling port, which is fitted with a dust cover and a self-locking valve.

[0012] Furthermore, the exhaust gas purification device 4 includes a multi-layer filtration structure, consisting of a metal filter layer, a ceramic catalyst layer, and an activated carbon adsorption layer.

[0013] Furthermore, the exhaust gas purification device 4 has an exhaust temperature range of 280-500℃.

[0014] Furthermore, the exhaust gas purification device 4 is detachable.

[0015] As can be seen from the above, compared with existing battery packs, this power supply system can support high power output, has a long endurance, and is simple and quick to recharge, ensuring continuous system operation. There is no need to replace or recharge batteries mid-operation. Compared with ordinary generator power supply systems, this system does not produce exhaust fumes and is quieter. It avoids problems such as failure to start after prolonged storage, and malfunctions in bumpy environments or when the generator is exposed to air intake, providing a more stable and reliable power supply.

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0021] To address the problem of the lack of a means to quickly and accurately adjust the output voltage and the difficulty in providing a stable constant voltage in the existing technology.

[0022] This utility model provides a high-power, long-range vehicle-mounted power supply system. Please refer to [link / reference]. Figure 1 and Figure 2 This application uses a diesel generator 1 for power supply. The range can be customized according to specific requirements based on the fuel tank size, and it can quickly refuel when the fuel is low, with a refueling time far less than the battery charging time. Furthermore, a liquid level sensor 3 is added to the fuel tank to monitor the fuel level at any time and provide an alert when the fuel level is low. The power supply system consists of a diesel generator 1, an electronic fuel pump 2, a starting battery, and an exhaust gas purification device 4, specifically including:

[0023] The oil inlet of the diesel generator 1 is connected to the electronic oil pump 2, which is connected to the starter battery via a relay. The electronic oil pump 2 is activated by the relay each time the generator starts. The exhaust outlet of the diesel generator 1 is equipped with an exhaust gas purification device 4, which is used to purify PM particles, mainly carbon, in the exhaust gas and reduce noise.

[0024] Further, refer to Figure 3 The electronic oil pump 2 is linked to the relay through a control circuit. When the generator starts, the relay automatically triggers the electronic oil pump 2 to run.

[0025] An electronic oil pump 2M1 was added to the generator's oil inlet, shared with the generator's starter battery U1. Each time the generator starts, the electronic oil pump 2 is activated via the control relay KA1. This ensures that even after the generator has been stationary for an extended period, oil can still be returned to the inlet, and air can still be introduced for normal starting. Furthermore, when used on moving vehicles, the generator's air intake continues to supply oil to the unit even on bumpy roads, ensuring stable operation of the generator unit.

[0026] Furthermore, a liquid level sensor 3 is installed inside the fuel tank to detect the fuel level in real time.

[0027] Furthermore, the liquid level sensor 3 is connected to the vehicle display terminal and is used to issue a warning signal when the fuel level is low.

[0028] Furthermore, the fuel tank is also equipped with a quick refueling port, which is fitted with a dust cover and a self-locking valve.

[0029] Furthermore, the exhaust gas purification device 4 includes a multi-layer filtration structure, consisting of a metal filter layer, a ceramic catalyst layer, and an activated carbon adsorption layer.

[0030] Furthermore, the exhaust gas purification device 4 has an exhaust temperature range of 280-500℃.

[0031] Furthermore, the exhaust gas purification device 4 is detachable.

[0032] The exhaust gas purification device 4 in this application can purify PM particles, which are mainly carbon, in the exhaust gas of generators, and reduce noise by 5-10 decibels. The black smoke removal rate is as high as 90%-98%, the CO removal rate is 40%-50%, and the HC removal rate is 40%-50%.

[0033] The present invention has the following advantages:

[0034] Compared with existing battery packs, this power supply system can support high power output, has a long battery life, and is easy and quick to recharge, ensuring continuous operation of the system without the need to replace or recharge the batteries midway.

[0035] Compared to conventional generators, this system produces no exhaust fumes and is quieter. It avoids issues like failure to start due to prolonged inactivity or generator malfunction caused by air intake during bumpy rides, resulting in a more stable and reliable power supply.
