Abstract
The utility model proposes control box on a kind of electric automobile line of band automatic switchover function of current, plug that this side of connection power grid uses has magnetic field detection circuit in the plug for the standard plug of the control box maximum current grade；In addition a high current is configured with to the changeover plug of low current, and the standard plug by the standard plug switching of maximum current grade for reduced-current grade, the changeover plug inside the standard plug junction of maximum current grade with being embedded with one block of magnet；To when having magnet, control unit inside control box is converted to low current pattern by high current pattern for magnetic field detection electric circuit inspection in the standard plug of control box maximum current grade, and by corresponding signal output to electric automobile end.
Description
Technical field
The present invention relates to control box on a kind of electric automobile line of band automatic switchover function of current.
Background technology
In recent years, more and more extensive with the application of electric automobile, charging problems increasingly attract attention.Charging is solved to ask
Flexibly the approach of low cost is that normal domestic socket is converted to and can charged for electric car by control box on line to one of topic
Power supply.Control box sends corresponding signal to vehicle according to different power grades on line, and vehicle is according to signal realization pair
The charge power answered, avoids charge power too big, the situation that normal domestic socket is burnt.
The content of the invention
1）The technical problem of solution
, it is necessary to be selected to control on different lines according to the civil socket of different capacity during control box on using line
Box processed, or adjust the power grade of control box on line.When such as using 10A charging sockets, it should be charged using 10A, be filled using 16A
During electrical socket, it should be charged using 16A.With control box on the line for adjusting power grade, it is easy to occur forgetting to adjust in use
It is incorrect that section power or maloperation cause power grade to set, and burns socket, or even trigger fire.The present invention can be automatically according to
Different sockets realizes automatic adjustment charging current, avoids above-mentioned danger.
2）Technical solution
The present invention proposes control box on a kind of electric automobile line of band automatic switchover function of current, its basic principle is profit
With the permanent magnet set in dedicated changeover plug, different charging plugs is identified.
The plug that control box carries is the plug of high current, during using the plug, is directly inserted on the socket of high current, such as
16A sockets.If it is desired that with the charging socket of smaller current, such as the socket of 10A, then supporting dedicated convert plug is found control
On the plug of box processed, the plug of 16A is converted to the plug of 10A.One permanent magnet is set in the dedicated convert plug, works as control
Box processed detects the charging current that automatically switches when the plug is inserted into.
3）Beneficial effect
The present invention can realize automatic adjustment charging current automatically according to different sockets, avoid power grade from setting not just
Really, socket is burnt, or even triggers the danger such as fire.
Brief description of the drawings
Fig. 1 is the schematic diagram of control box on the electric automobile line with automatic switchover function of current.1- control box, 2- control box
Plug, 3- magnetic field detections circuit, 4- changeover plugs, 5- embed magnet, 6- car rifles
Embodiment
Control box on a kind of electric automobile line of band automatic switchover function of current, the plug that connection power grid this side uses for
The standard plug of the control box maximum current grade, has magnetic field detection circuit in the plug；In addition a high current is configured with to arrive
The changeover plug of low current, by the standard plug that the standard plug switching of maximum current grade is reduced-current grade, the conversion
Plug inside the standard plug junction of maximum current grade with being embedded with one block of magnet；The standard of control box maximum current grade is inserted
For magnetic field detection electric circuit inspection in head to when having magnet, the control unit inside control box is converted to low current by high current pattern
Pattern, and by corresponding signal output to electric automobile end.
Magnetic field detection circuit is made of in parallel with thermo-sensitive resistor after a magnetic switch and a resistance series connection, is so utilized
This both may determine that whether changeover plug is plugged can also be by thermo-sensitive resistor measurement temperature.Magnetic field detection circuit can also be used
One Hall switch chip and a thermo-sensitive resistor are built, and can equally reach similar effect.
Since magnetic field detection circuit only has two external nodes, only need to be connected to by a signal wire and ground wire
Control box.
One block of magnet be embedded with inside changeover plug, which is nonconducting ferrite permanent magnet, so can to avoid turn
Insert the danger of an internal short-circuit.
