Description
Technical field
The invention belongs to pure electric coach control technology fields, specifically, being related to a kind of disconnected low tension of electric motor coach intelligence
Device.
Background technique
Automobile is generally made of four engine, chassis, vehicle body, electrical equipment component parts, and electrical equipment is wherein heavy
The component part wanted, wherein power supply unit of the low tension as electrical equipment, it is seen that importance of the low tension on vehicle performance,
There is no power supply, electrical equipment can not then work, therefore protect low tension not power shortage, then most important.
Since new energy pure electric coach is unlike conventional fuel oil car, conventional fuel oil car is started in the state of starting
Chance issues sound, what driver can will be apparent that know car either with or without power-off, and pure electric coach in upper high pressure and not on
In the case where high pressure, car be all it is mute, motor is that whether will not have voltage because of motor both ends and make a sound, in this way
Driver will be allowed to generate inadaptable, forget to pull out key, and the not upper high pressure of car, be constantly in ON grades of electric positions, no
The electricity of the battery consumption stopped, when battery cannot supplement always, electricity is fewer and fewer, and voltage also decreases.But
BMS on vehicle, VCU, the controllers such as MCU will could at least work under the supply voltage of 15V or so, and voltage is inadequate, and car is certainly
Traveling can not so be started, at this time to re-power success, then necessarily charged a battery, if not ready-made power supply supplies
Electricity just will increase bigger work difficulty.It is serious to reduce efficiency, while electric energy is wasted, accelerate the old of battery
Change speed.
Summary of the invention
The purpose of the present invention is to provide a kind of disconnected low pressure electric installations of electric motor coach intelligence.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of electric motor coach intelligently disconnected low pressure electric installation, including entire car controller, high voltage power distributing cabinet and air switch, vehicle
Controller is connect by CAN bus with high voltage power distributing cabinet and carries out CAN communication, the input terminal and low-voltage power supply equipment of entire car controller

End is connected on 105 low-voltage circuits or on 106 low-voltage circuits, the switch state of entire car controller intelligent control air switch.
As further scheme of the invention, the step of the entire car controller intelligent control air switch state, including
Following steps:
Entire car controller judges whether the low-voltage circuit of electric motor coach is in running order, if low-voltage circuit is in inoperative
State, entire car controller, which is not done, to react, if low-voltage circuit is in running order, into subsequent work process；
Entire car controller judges whether the high-tension circuit of electric motor coach is in running order, if high-tension circuit is in work shape
State, entire car controller, which is not done, to react, if high-tension circuit is in off working state, into subsequent work process；
Working time A of entire car controller start recording low-voltage circuit under conditions of high-tension circuit is turned off, works as work
Time A be no more than setting time B when, entire car controller does not react, when operating between A be greater than setting time B when, full-vehicle control
Device controls air switch and disconnects low-voltage circuit.
As further scheme of the invention, the low-voltage power supply equipment is the battery that supply voltage is 24V.
Beneficial effects of the present invention: the present invention can be under conditions of the high-tension circuit of electric motor coach stops working, to electricity
The low-voltage circuit of dynamic car carries out intelligent power-off, prevents from leading to low-voltage power supply equipment electricity stream due to forgetting disconnection low-voltage circuit
It loses, voltage reduces and can not cause electric motor coach that can not normally start work for power electrical apparatus.
Detailed description of the invention
The present invention will be further described below with reference to the drawings.
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the flow chart of vehicle control unit controls air switch state.
Specific embodiment
