Embodiment 1

[0039] We take Shaanxi Auto Heavy Truck N3000 as the test object for research, which is equipped with Weichai 6BT5.9 diesel engine and Fengfan low-temperature battery1. The starting process of the engine at -40°C can be divided into four stages: starting stage, heating stage, trembling stage and stable operation stage. Such as Figure 6 shown.

[0040]In the starting stage, each friction pair of the engine driven by the starter starts to rotate from a standstill, and the oil supply between the friction pairs is insufficient, forming semi-dry friction or dry friction, resulting in a large starting resistance torque and high energy consumption. As the engine rotates, the lubrication state between the friction pairs gradually improves, the resistance becomes smaller, and the speed rises slowly. At the same time, the piston compresses the air, which gradually increases the temperature in the cylinder and improves the fuel atomization. To create favorable conditions for ignition,...

Embodiment 2

[0064] Experimental analysis EDLC capacitor 21 The low-temperature starting emergency power system is installed on the Shaanxi Automobile N3000 heavy-duty truck, and the cold-low temperature and ultra-low temperature starting applications have been carried out in Xinjiang and three northeastern provinces.

[0065] Under the condition of loading the vehicle at an ambient temperature of -41°C: first, the EDLC capacitor starting power supply device 2 is connected in parallel with the original power supply system as an auxiliary power supply; the microcontroller 22 collects ambient temperature signals through a temperature sensor to determine the current Whether auxiliary power is needed for starting (the software sets the auxiliary power to work when the environment is lower than 5°C); then, charge the EDLC capacitor 21 through the boost charging circuit, and the charging process takes nearly 2 minutes. After the charging is completed, that is, the charging indicator light goes ou...

Abstract

The invention discloses a heavy-duty vehicle starting emergency power system with EDLC capacitors, and specifically relates to the field of low-temperature starting power systems for automobiles. Starting power supply device; EDLC capacitor starting power supply device is composed of EDLC capacitor, microcontroller, relay, sensor, clock / pulse width modulation module and automatic control switch, and integrated on the system circuit board; the battery is charged to the EDLC capacitor through a boost charging circuit Charge. The system of the present invention utilizes the characteristics of large capacitance, long charge and discharge life, short charging time, high discharge current, small internal resistance and wide normal operating temperature range, etc., and replaces part of the energy and power supply of the storage battery through electronic control technology The energy of the system battery is released at the right time, which improves the effective energy and starting ability of the car power supply.

Description

technical field [0001] Embodiments of the present invention relate to the field of low-temperature starting power supply systems for automobiles, in particular to an emergency power supply system for starting heavy vehicles with EDLC capacitors. Background technique [0002] Low-temperature starting performance is one of the main performances of heavy-duty vehicles. If the vehicle is left at low temperature for too long, or is in a state of power consumption for a long time, the battery feed cannot be started or it will take a long time to start. Can bring a lot of inconvenience to the user, especially for vehicles such as military use, fire-fighting and first aid, even thus delay the opportunity, cause immeasurable loss. [0003] Due to geographical location and natural conditions, the northern, northwestern, and northeastern regions of my country have very harsh climate conditions, and the lowest temperature is even lower than -40 to -60°C. Under such environmental condi...
