Description
Technical field
The present invention relates to automotive field, in particular it relates to a kind of new-energy automobile starts system.
Background technology
Growing along with automotive engineering, the electronic devices and components on new-energy automobile are significantly increased, and cause
The increase of low pressure power consumption so that discharged or defective battery problem day by day appears.At vehicle normal operating condition,
Owing to there being dc-dc to power, there is not use problem, but when after stock idle a period of time,
The accumulator of vehicle can cause discharged or defective battery after a period of time due to the increase of static power consumption, thus leads
Cause vehicle cannot start.Owing to the electronic devices and components of current new-energy automobile increase part a lot, only pass through
Increase accumulator capacity and be difficult to meet the use requirement of vehicle.And a kind of system that the present invention proposes, pass through
Original circuit increases part components and parts, in the case of discharged or defective battery, remains to vehicle launch.
Summary of the invention
It is an object of the invention to provide a kind of new-energy automobile and start system, this system cannot make in accumulator
Used time is still able to start vehicle.
To achieve these goals, the present invention provides a kind of new-energy automobile to start system, and this system includes:
Dc-dc, is converted into the high-tension electricity of electrokinetic cell low tension, and exports this low tension；Whole
Vehicle controller, this entire car controller is connected with described dc-dc, is used for controlling described DC-DC
Transducer；Accumulator, being used for is described entire car controller and institute when described new-energy automobile normally starts
State dc-dc to power；And accessory power supply, with described dc-dc and described accumulator
Being connected, being used for cannot be for described entire car controller and described DC-DC in the case of powering in described accumulator
Transducer is powered.
Described accessory power supply provides 9V voltage.
Described accessory power supply is connected with described dc-dc and described accumulator by switch K2.
Wherein said switch K2 is from return delay switch.
This system also includes that switching K1, this switch K1 is connected to described electrokinetic cell and described DC-DC
Between transducer, in order to ensure high-voltage safety.
After wherein said new-energy automobile starts, described dc-dc can utilize described power current
Described storage battery power supply is given in pond.By technique scheme, in arrangement and high and low pressure wire harness principle
In the case of design allows, according to feature and the working condition of each key components and parts of vehicle, at car load
During design, one accessory power supply of increase is as emergency vehicle startup circuit part, when access failure occurs in accumulator
Or power shortage etc. cannot use situation time, be still able to make vehicle launch.
Other features and advantages of the present invention will be described in detail in detailed description of the invention part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and constitutes the part of description, with
Detailed description below is used for explaining the present invention together, but is not intended that limitation of the present invention.?
In accompanying drawing:
Fig. 1 is the schematic diagram of the vehicle starting system of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in detail.It should be appreciated that
Detailed description of the invention described herein is merely to illustrate and explains the present invention, is not limited to this
Bright.
Fig. 1 is the schematic diagram of the vehicle starting system of the present invention.As it is shown in figure 1, accumulator 103 is whole
Vehicle controller 105 and dc-dc 102 are powered, and when key, to get to ACC(not shown) position
After, entire car controller 105 receives enable signal, is then activated and starts working；Now full-vehicle control
Device 105 sends to dc-dc 102 and enables signal to start dc-dc, by DC-DC
Transducer 102 provides the electric energy starting vehicle.But, after vehicle is idle for a long time, accumulator 103
Cause due to the increase of electrostatic power consumption power shortage or because of other reasons cannot use time, will cause vehicle without
Method starts.
As it is shown in figure 1, in the case of arrangement and high and low pressure wire harness principle design allow, according to
The feature of vehicle and the working condition of each key components and parts, in dc-dc 102 and accumulator
An accessory power supply 104 in parallel between 103, and increase a switch K2, this switch on the line
K2 is for controlling the break-make of accessory power supply.When accumulator 103 cannot use, press switch K2 and connect
After accessory power supply 104, entire car controller 105 receives enable signal, is then activated and starts working；
Now entire car controller 105 sends to dc-dc 102 and enables signal to start DC-DC conversion
Device 102, is then utilized electrokinetic cell 101 to provide the electric energy of vehicle launch by dc-dc 102.
After vehicle launch, on the premise of meeting car load power consumption, dc-dc 102 gives electric power storage
Charge in pond 103.The wherein fastp-acting fuse 108 within electrokinetic cell and the quick fuse on high-voltage wiring harness
Device 109 can provide circuit protection effect, can quick fuse when overload or short circuit.Accumulator 103
It can be 12V accumulator.This system also includes switching K1, wherein before pressing switch K2, it should
Guarantee that switching K1 is in closure state, to ensure the high input voltage of dc-dc 102.Wherein
Switch K1 is electrokinetic cell Manual power-down switching, not using vehicle for a long time when, in order to safety can
Manually to disconnect electrokinetic cell 101.Preferably, switch K2 uses from return delay switch, and it is being pressed
After lower 10s can self-return, to save the electricity of accessory power supply and ensure its number of applications and avoid by mistake
Operation, it is noted, therefore, that vehicle to be started in 10s after pressing switch K2, needs the most after a time out
Re-operate.Preferably, the voltage that accessory power supply 104 provides is unsuitable excessive, in order to avoid impact is arranged.
Preferably, the power supply that accessory power supply 104 can use voltage to be 9V, it should be appreciated that this accessory power supply is permissible
For known suitable any type of power supply.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing, but, the present invention does not limit
Detail in above-mentioned embodiment, in the technology concept of the present invention, can be to the present invention
Technical scheme carry out multiple simple variant, these simple variant belong to protection scope of the present invention.
