Description
Technical field
The present invention relates to electric vehicle engineering field, more particularly to a kind of electric automobile emergency starting device.
Background technology
Current China State of Air pollution is extremely serious, and in city atmospheric environment, TSP concentration is generally exceeded；Sulfur dioxide pollution is always in higher level；Pollutant of vehicle exhaust total emission volumn increases sharply；For propulsion energy-saving reduce discharging, promote air contaminant treatment, current China and to the world all accelerate new-energy automobile industrialization, therefore, electric automobile style also will be more and more.
No matter orthodox car or electric automobile, electric energy is provided typically by vehicle booster battery so as to normally start vehicle, and often client can run into and vehicle is normally started phenomenon causes booster battery brownout because vehicle is long placed in or booster battery is aging etc..Traditional solutions are by charging to booster battery or being started using other vehicle booster batteries overlap joint in parallel, can only connection with automotive vehicles company after-sale service station solve problem if not possessing in the case of above-mentioned two condition client, waste while so trouble and operational security risk being brought to client client's quality time, motor corporation's after service cost is also increased, motor corporation's brand influence is reduced.Now the booster battery brownout with regard to electric automobile causes the problem that vehicle normally cannot start, and an emergency starting device is set up to electric automobile.
The content of the invention
Solve because vehicle is long placed in or booster battery is aging etc. that brownout phenomenon causes vehicle start navigational challenge it is an object of the invention to provide a kind of, eliminate the trouble and operational security risk brought to client because of booster battery, also quality time and money have been saved for client simultaneously, motor corporation's after service cost is reduced, the electric automobile emergency starting device of motor corporation's brand influence is improved.
The solution of the present invention is such：
A kind of electric automobile emergency starting device, including connection electrokinetic cell and the DC/DC transducers of boosting battery, entire car controller, ignition switch, it is characterised in that：Between the control end of electrokinetic cell and DC/DC transducers and be connected to relay switch end and emergency starting switch, the ignition switch rear end is connected with the Control end and entire car controller positive source for accessing entire car controller, boosting battery negative pole is connected with entire car controller negative pole, and the control of the relay is terminated at the 8th port of ignition switch rear end and entire car controller.
It is an advantage of the invention that solving because vehicle is long placed in or booster battery is aging etc., brownout phenomenon causes vehicle start navigational challenge, eliminate the trouble and operational security risk brought to client because of booster battery, also quality time and money have been saved for client simultaneously, motor corporation's after service cost is reduced, motor corporation's brand influence is improved.
Description of the drawings
Fig. 1 is the circuit theory diagrams of the present invention.
Specific embodiment
It is of the invention as shown in Figure 1, DC/DC transducers, entire car controller including connection electrokinetic cell and boosting battery, ignition switch 3, between the control end of electrokinetic cell and DC/DC transducers and be connected to relay 2 switch terminals and emergency starting switch 1, the ignition switch rear end is connected with the Control end and entire car controller positive source for accessing entire car controller, boosting battery negative pole is connected with entire car controller negative pole, and the control of the relay is terminated at the 8th port of ignition switch rear end and entire car controller.
The relay 2 for accessing 8 port of entire car controller is connected with 3 rear end of ignition switch, by 8 port controlling relay of entire car controller, 2 switch terminals, two joint of switch terminals is respectively turned on the positive pole of electrokinetic cell and the control end of DC/DC transducers is connected to by control line 4；The entire car controller is provided with 8 port of control port of the adhesive of relay switch end or opening, emergency starting button 1 is point driving switch, in the present embodiment, boosting battery normal working voltage is set in 10V to 13.8V, and the control of fault-signal is installed on the red led of combination instrument lights carries out malfunction coefficient.
The course of work of the present embodiment is as follows：
（1）When booster battery voltage is more than 10V, start electric automobile ignition switch, vehicle control unit of electric vehicle electrifying startup, system initialization, entire car controller is gathered and stores auxiliary battery voltage, entire car controller sets 8 port of entire car controller as low level, now relay coil adhesive, relay contact closure is turned on, the port 5 of DC/DC transducers receives power battery anode high potential signal, DC/DC transducers normally start and power battery voltage are converted into 13.8V voltage outputs, booster battery is charged, the auxiliary battery voltage of entire car controller collection simultaneously, if auxiliary battery voltage is equal to 13.8V voltages, combination instrument is received entire car controller CAN signal and is shown normally by green indicating lamp；If auxiliary battery voltage is set to running voltage before low level equal to 8 port of entire car controller, combination instrument receives entire car controller CAN signal and carries out fault alarm by red led；
（2）When booster battery voltage is less than 10V，Start electric automobile ignition switch，Entire car controller initialization failure，The delay time of the present embodiment is set as 3s，More than emergency starting button 3s is pressed now，DC/DC transducer ports 5 receive power battery anode high potential signal，DC/DC transducers normally start and power battery voltage are converted into 13.8V voltage outputs，Booster battery is charged，Vehicle control unit of electric vehicle normally starts simultaneously，System initialization，Entire car controller gathers auxiliary battery voltage，Judge that auxiliary battery voltage is equal to 13.8V，Entire car controller sets 8 port of entire car controller as low-voltage，Now relay coil adhesive，Relay contact closure is turned on，Combination instrument receives entire car controller CAN signal and passes through red led display device failure；Now entire car controller limits Vehicle Speed and is less than 40KM/h, and carries out fault alarm by combination meter for electric automobile red led.After diagnosis booster battery is normal, after eliminating entire car controller failure source code, the restriction to vehicle speed 40KM/h is released, combination meter for electric automobile green indicating lamp shows that normally vehicle can normally travel.
（3）When vehicle launch is normal, such as maloperation emergency starting button 1, as DC/DC transducers normally start, does not interfere with the work of vehicle circuitry.
In being embodied as, the running voltage of electrokinetic cell optionally can determine the present invention, not limited by the present embodiment；The minimum normal working voltage of boosting battery can optionally determine, not limited by the present embodiment.
