Demodulator device for charging intelligent electric vehicle

Abstract

The invention discloses a demodulator device for charging an intelligent electric vehicle. The demodulator device structurally comprises a connecting socket end, a charging head connecting regulator,a regulating control regulating key and a protective shell; the charging head connecting regulator is of an L-shaped structure, and comprises a low-degree acceleration connection group, a high-degreeacceleration connection group, a protective envelope, a trigger starting group, a to-be-squeezed pushing device, a pushing rotation control device, a conductive connection head, a pushing translationdevice, and a pulling gear group; and the conductive connection head is embedded in the end, away from the high-degree acceleration connection group, ofthe protective envelope, and one end of the pushing translation device is mechanically connected with the pulling gear group. Based on the prior art, according to the demodulator device for charging the intelligent electric vehicle, after easy operation is carried out on the demodulator device, the charging speed of the demodulator device can be adjusted, if the demodulator device is in urgent need of use, the frequency of the demodulator device can be adjusted to fast charge, if the demodulator device is not in urgent need of use, and the time is enough, the frequency of the demodulator device can be adjusted to slowly charge, and settingthrough conditions can be achieved.

[0002] The electric vehicle charger is a charging device specially configured for the battery of the electric bicycle! Classification of chargers: with and without power frequency transformers, which can be divided into two categories. Freight three-wheel chargers generally use chargers with power frequency transformers, which are large in size, heavy in weight, and cost electricity, but reliable and cheap; Electric bicycles and electric motorcycles use so-called switching power supply chargers, which save electricity and have high efficiency, but are fragile. Since the input circuit of electric vehicle chargers works at high voltage and too much current, the failure rate is the highest, such as High-voltage and high-current rectifier transistors, filter capacitors, switching power tubes, etc.; secondly, the rectifier diodes, protection diodes, filter capacitors, current-limiting resistors, etc. of the output rectifier part are more easily damaged, and then the feedback part and protection of the pulse width modulation controller. In the circuit part, under normal circumstances, the blown fuse tube indicates that there is a short circuit or overcurrent fault in the internal circuit of the charger. In addition, the fluctuation and surge of the grid voltage will cause the current in the charger to increase instantaneously and cause the fuse to blow. Intermittent charging of different lengths is more likely to cause damage to the charger.

[0003] For the current charging of electric vehicles, because we cannot watch and pay attention to the time, it is possible to charge the battery too much, or to charge too little and not enough, which is not good for the battery and affects the life of the vehicle. greater damage
