Description
Technical field
The present invention relates to automotive field, particularly, relate to a kind of new-energy automobile and start system.
Background technology
Growing along with automotive technology, the electronic devices and components on new-energy automobile significantly increase, and have caused the increase of low pressure power consumption, and discharged or defective battery problem is day by day appeared.At vehicle normal operating condition, owing to there being the power supply of DC-DC conv, there is not use problem, but when vehicle is after idle a period of time, the storage battery of vehicle can cause due to the increase of static power consumption discharged or defective battery after a period of time, thereby causes vehicle to start.Because the electronic devices and components increase part of current new-energy automobile is a lot, only by increasing accumulator capacity, be difficult to meet the operating needs of vehicle.And a kind of system that the present invention proposes, by increase part components and parts on original circuit, in discharged or defective battery situation, still can be got up vehicle launch.
Summary of the invention
The object of this invention is to provide a kind of new-energy automobile and start system, this system still can start vehicle when storage battery cannot be used.
To achieve these goals, the invention provides a kind of new-energy automobile and start system, this system comprises: DC-DC conv, converts the high-tension current of electrokinetic cell to low tension, and export this low tension; Entire car controller, this entire car controller is connected with described DC-DC conv, for controlling described DC-DC conv; Storage battery, for being described entire car controller and the power supply of described DC-DC conv when described new-energy automobile normally starts; And accessory feed, be connected with described storage battery with described DC-DC conv, for be described entire car controller and the power supply of described DC-DC conv in the situation that described storage battery cannot be powered.
Described accessory feed provides 9V voltage.
Described accessory feed is connected with described storage battery with described DC-DC conv by K switch 2.
Wherein said K switch 2 is from return time-delay switch.
This system also comprises K switch 1, and this K switch 1 is connected between described electrokinetic cell and described DC-DC conv, in order to guarantee high-voltage safety.
After wherein said new-energy automobile starts, described DC-DC conv can utilize described electrokinetic cell to described storage battery power supply.Pass through technique scheme, the in the situation that of arrangement and the permission of high and low pressure wire harness principle design, according to the service conditions of the feature of vehicle and each key components and parts, when designing, car load increases an accessory feed as emergency vehicle startup circuit part, when situation that access failure or power shortage etc. cannot use appears in storage battery, still can make vehicle launch.
Other features and advantages of the present invention partly in detail are described the specific embodiment subsequently.
Accompanying drawing explanation
Accompanying drawing is to be used to provide a further understanding of the present invention, and forms a part for specification sheets, is used from explanation the present invention, but is not construed as limiting the invention with the specific embodiment one below.In the accompanying drawings:
Fig. 1 is the schematic diagram of vehicle starting system of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the present invention, is not limited to the present invention.
Fig. 1 is the schematic diagram of vehicle starting system of the present invention.As shown in Figure 1, storage battery 103 is 102 power supplies of entire car controller 105 and DC-DC conv, and when key, to get to ACC(not shown) behind position, entire car controller 105 is received enable signal, be then activated and start working; Now entire car controller 105 sends enable signal to start DC-DC conv to DC-DC conv 102, and the electric energy that starts vehicle is provided by DC-DC conv 102.Yet, after vehicle is for a long time idle, when storage battery 103 causes power shortage or cannot use because of other reasons due to the increase of static power consumption, will cause vehicle to start.
As shown in Figure 1, the in the situation that of arrangement and the permission of high and low pressure wire harness principle design, according to the service conditions of the feature of vehicle and each key components and parts, an accessory feed 104 in parallel between DC-DC conv 102 and storage battery 103, and increasing on the line a K switch 2, this K switch 2 is for controlling the break-make of accessory feed.When storage battery 103 cannot be used, to press K switch 2 and connect after accessory feeds 104, entire car controller 105 is received enable signal, is then activated and starts working; Now entire car controller 105 sends enable signal to start DC-DC conv 102 to DC-DC conv 102, then by DC-DC conv 102, utilizes electrokinetic cell 101 that the electric energy of vehicle launch is provided.
After vehicle launch, meeting under the prerequisite of car load power consumption 102 accumulators 103 chargings of DC-DC conv.Wherein the quick acting fuse 108 of electrokinetic cell inside and the quick acting fuse 109 on high-voltage wiring harness can provide circuit protection effect, can quick fuse when overload or short circuit.Storage battery 103 can be 12V storage battery.This system also comprises K switch 1, wherein, before pressing K switch 2, should guarantee that K switch 1 is in closure state, to guarantee the high input voltage of DC-DC conv 102.Wherein K switch 1 is electrokinetic cell Manual power-down switching, when not using vehicle for a long time, for safety can manually disconnect electrokinetic cell 101.Preferably, K switch 2 adopts from return time-delay switch, and it can self-return after pressing 10s, to save the electric weight of accessory feed and to guarantee its number of applications and avoid maloperation, therefore, should note will starting vehicle in pressing the rear 10s of K switch 2, otherwise need again to operate after overtime.Preferably, the voltage that accessory feed 104 provides is unsuitable excessive, in order to avoid impact is arranged.Preferably, it is the power supply of 9V that accessory feed 104 can adopt voltage, should be appreciated that this accessory feed can be known suitable any type of power supply.
Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
