Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature starting, in particular to a low-temperature starting power supply. Background Art

[0002] The low-temperature starting power supply adopts a new energy storage element, a Farad-level supercapacitor, which is designed and manufactured as an auxiliary power supply device specifically for improving the difficulty of starting the internal combustion engine under low-temperature environmental conditions. It has a series of characteristics such as rapid charging, large discharge current, strong environmental adaptability, and long service life. It can replace the on-board battery to start various combustion engine equipment of the vehicle, and can also be used as a short-term high-power DC power supply for electrical equipment.

[0003] Low-temperature starting power supplies can be used for electric starting devices of various large-scale load-carrying and special vehicles and ships. When supercapacitors are used in parallel with the electric starting batteries of diesel engines, the starting time of the diesel-generator set is shortened due to the increase in starting power, and the rotation acceleration of the diesel engine is increased, ensuring the reliability of starting, especially at low temperatures and when the battery pack is insufficient or the parameters are deteriorating. Large diesel engines can be shut down at any time and started continuously. The use of supercapacitors can improve the quality of fuel ignition, reduce fuel consumption, reduce machine wear, reduce the maximum current load of the battery pack during starting, reduce the impact of starting on the power consumption of other equipment, extend the service life of the battery, reduce operating costs, and improve economic benefits.

[0004] At present, almost all domestic enterprises are using lead-acid batteries as power sources for generator sets, but lead-acid batteries have the problem of poor starting performance. At low temperatures, the starting power supply designed with traditional lead-acid batteries has poor low-temperature starting performance. The lower the ambient temperature, the worse the discharge performance, which is not conducive to people's use. For this reason, we provide a low-temperature starting power supply to solve the above problems. Utility Model Content
