A multi-port charging device

Abstract

The invention discloses a multi-port charging device, which comprises an on-off execution unit, wherein the on-off execution unit comprises a control module, a monitoring module, an on-off module anda conversion module. The control module is capable of receiving a second signal from the first control unit and sending an on-off command signal to the on-off module according to the second signal. The control module, the monitoring module, the on-off module and the conversion module jointly form an on-off control branch, wherein the on-off control branch is juxtaposed with at least one group, andeach group corresponds to a charging line; The on-off execution unit further comprises a selection module, and the control modules on each on-off control branch can be connected with the first control unit through the selection module. The invention can provide a centralized outdoor charging place for an electric vehicle, which is convenient for a user to charge directly without leading out a wire outword from indoors, and is more convenient and safe.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a multi-port charging device. Background technique [0002] After electric vehicles are popularized in large numbers, the charging problem of electric vehicles has always been a prominent problem. As the current residences tend to be high-rise, residents who own electric vehicles can only push the electric vehicles into their rooms if they need to charge. inconvenient. For non-high-rise ground-floor residential users, they often choose to throw the cable downward from the upper floor and lead the socket to the outdoor ground for charging. Unfavorable factors such as friction with walls are prone to safety accidents.

Problems solved by technology

As the current residences tend to be high-rise, residents who own electric vehicles can only push the electric vehicles into their rooms if they need to charge. inconvenient

For non-high-rise ground-floor residential users, they often choose to throw the cable downward from the upper floor and lead the socket to the outdoor ground for charging. Unfavorable factors such as friction with walls are prone to safety accidents

In addition, due to charging to the lead wire downstairs, out of sight, there is no separate overload protection measure, and when the charging is completed, the circuit cannot automatically cut off the power, so that the electric vehicle is overcharged for a long time, which not only shortens the life of the battery itself, but also overheats the charger, and It is easy to cause internal short circuit, which is also an important cause of fire accidents

In addition, the general community owners charge mostly at night, if there is a danger, the harm will be even greater
