AC-DC charging all-in-one machine gun head temperature monitoring circuit and monitoring method

Abstract

The invention relates to the field of alternating-current and direct-current charging all-in-one machines, in particular to an AC-DC charging all-in-one machine gun head temperature monitoring circuitand method. The circuit comprises a power supply control unit, an automatic protection unit, an auxiliary unit and a temperature monitoring unit, wherein the power supply control unit is used for controlling and converting an input voltage, so that the voltage input into the storage battery conforms to a working voltage required by an automobile, and the input voltage is stabilized; the automaticprotection unit triggers automatic power-off when the temperature value of the gun head is too high, so that the charging all-in-one machine is better protected; the auxiliary unit performs fault alarm and signal feedback of the charging all-in-one machine; the temperature monitoring unit is used for monitoring the temperature of the charging all-in-one machine gun head; according to the circuit,the charging voltage of the charging integration of the electric automobile is improved, and the alternating current and the direct current are converted, so that one charging box can charge different automobile batteries.

Description

technical field [0001] The invention relates to the field of an AC-DC charging integrated machine, in particular to a temperature monitoring circuit and a monitoring method for an AC-DC charging integrated machine gun head. Background technique [0002] With the development of science and technology, human beings realize that while carrying out technological development, we must also protect the environment in which we live; although traditional gasoline vehicles have excellent power effects, the exhaust gas they remove is harmful to the environment and human body. There is a lot of damage, and the excessive use of cars makes the earth's non-renewable resources gradually disappear. [0003] Electric vehicles are new energy vehicles that use electricity as energy, and are also the key development direction of automobiles. Electric vehicles are no different from traditional vehicles in terms of appearance, interior decoration, and operation. The main source of power for electr...

Problems solved by technology

[0004] The all-in-one charging machine is a device for charging electric vehicles, and it is a power conversion device with specific functions used when charging the battery; when the all-in-one charging machine for electric vehicles in the prior art is working, although it can protect the battery temperature, However, it is impossible to monitor the temperature of the gun head of the charging all-in-one machine, which will accelerate the aging of the gun head, thereby reducing the charging efficiency. When it is dangerous, it will cause a short circuit of the device and cause greater losses.
