Car emergency start power supply with preheat function

Abstract

The invention discloses an automobile emergency start power supply with a preheating function, and relates to the technical field of automobile emergency start. The power supply comprises a power supply shell (1), a first electrical core set (2), a second electrical core set (3), an electric heating film (4) for wrapping the first electrical core set (2), a main control panel (5) based on a single chip microcomputer, a temperature sensor (6), an analog quantity input module (7), a temperature display screen (9), a start preheating button (10), an electric heating controller (11), an emergency power supply output port (12), and a charging port (13). The power supply shell (1) is provided with a set of installation grooves for installing electric sockets and a display screen installation groove. The power supply comprises two electrical cores namely a lithium battery set and a lead acid battery set; the lithium battery set is used for supplying power for emergency start, the lead acid battery set supplies power to the preheating module, and thus the power supply can reliably supply power to an automobile in a low temperature environment, is worthy to popularize, and is very practical.

[0002] With the development of the times, cars have entered ordinary families, bringing great convenience to people's travel, but they will also encounter many problems. For example, cars cannot be started under certain special circumstances, which will bring great inconvenience to users. big trouble

At present, cars generally use batteries to start the engine. When the engine is started, the battery is charged by its own power generation system. Under normal circumstances, the power of the battery can be balanced. However, due to the aging of the car battery, insufficient charging, long-term storage or cold weather, It will lead to insufficient power supply of the battery and the failure of the generator to start normally, which will affect the normal use of the vehicle. If the vehicle is started multiple times at this time, it will also cause certain damage to the battery and starter; in order to solve the above problems, there are currently The appearance of emergency starting power supply and portable car starting power supply has solved this problem very well. The general emergency starting power supply uses a lithium battery with a large capacity, but the inherent charge and discharge temperature characteristics of lithium batteries are destined to often fail to discharge normally in the cold winter In the ignition state, the main reason is that the internal resistance of the lithium battery becomes high at low temperature and the output current decreases. Therefore, it is necessary to design a car emergency starter power supply with a preheating function that can be discharged normally at low temperature.
