Abstract

The invention relates to an output terminal polarity conversion device for quick charge. Six connection modes for a three-hole plug, with terminals N, E and L, and a storage battery are converted into a connection mode V+ / V-, the plug is connected to the output terminal + / - of quick charge equipment, and correct and safe charge of the quick charge equipment is guaranteed. The polarity of charged equipment is detected automatically, the output terminal polarity is adjusted to be as same as the polarity of the charged equipment, and the charged equipment is charged normally, so that a charging station charges the adjusted charged equipment according to the terminal polarity of the charged equipment. The charged equipment is rapidly connected between the output terminal P1 and the output terminal P2 of the quick charge equipment by any means, a switch automatically and directionally detects respective independent signals, switch-on and switch-off of relays and corresponding contacts are controlled through related control circuits, and smoothness of circuits corresponding to switch polarity is guaranteed, so that automatic conversion of charging circuit polarity is realized, and safety of the charged equipment is guaranteed.

Description

technical field [0001] The invention relates to a voltage polarity switching device, in particular to a fast charging output terminal polarity switching device. Background technique [0002] According to the market survey on the wiring methods of various brands, it is found that there are various charging plugs at the output end of the electric bicycle fast charging equipment for different brands of electric bicycles, especially the three-hole charging socket of the electric bicycle and the positive and negative terminals of the battery. There are 6 wiring methods (①N+, L-; ②L+, N-; ③N+, E-; ④E+, N-; ⑤L+, E-; ⑥E+, L-;). Damage the charging equipment and burn out the electric bicycle charging line. Contents of the invention [0003] The purpose of the present invention is to overcome the above deficiencies and provide a new solution: a fast charging output terminal polarity conversion device, which converts the 6 wiring modes of N, E, L three-hole plugs and batteries into ...
