Description

Electronlmobil utilizes DC/DC changer ignition initiation devices
Technical field
The invention belongs to electric vehicle engineering field, be specifically related to a kind of electronlmobil and utilize DC/DC changer ignition initiation devices.
Background technology
The world today day by day increases along with orthodox car, consequent motor vehicle exhaust emission, the environment for human survival problems such as green-house effect are on the rise, become the focus of world attention, therefore, pure electric automobile and hybrid vehicle and other energy saving environmental protection vehicles arise at the historic moment, and become one of important means of environmental protect economize energy.
Usually two power storage bags are had for electronlmobil, one is high voltage power battery storage bag, normally high-tension battery (HV), mainly become direct current (DC) to be stored in high voltage power power brick AC conversion by battery charger, become kinetic energy to discharge electric energy conversion by vehicular drive motor when the vehicle is running; Another power storage bag is that low-voltage electric energy stores bag, normally low pressure lead-acid storage battery (LV), mainly by DC-DC converter, the delivery of electrical energy of high voltage power battery storage bag is stored in bag to low-voltage electric energy, when needs use electronlmobil, low pressure lead-acid storage battery (LV) provides the normal power supply of 12V, carries out ignition trigger to electronlmobil.
Electronlmobil is similar with orthodox car, and the power supply needing DC12V carries out ignition trigger.The conventional low pressure lead-acid storage battery that usually adopts provides the normal power supply of DC12V to carry out ignition trigger, when the vehicle not used time comparatively of a specified duration standing time, the dark current that vehicles electrical part produces or some electrical part forget closedown, easily cause this low pressure lead acid storage battery tank discharge in debt, cause vehicle normally to start and damage with lead-acid storage battery.In addition, this lead-acid storage battery can take electronlmobil installing space, increases complete vehicle weight, increases the productive costs of electronlmobil.
Summary of the invention
The object of the invention is to overcome defect of the prior art, and provide a kind of structure simple, can reduce productive costs, the minimizing complete vehicle weight of electronlmobil and the electronlmobil of installing space utilize DC/DC changer ignition initiation devices.
The object of the present invention is achieved like this: comprise DC/DC changer, the positive pole of electrokinetic cell is connected with the input end of positive pole main relay contacts, the input end of positive pole main relay contacts is connected with one end of HVDC fuse, the other end of HVDC fuse is connected with the input end of battery isolator control, the mouth of battery isolator control is connected with the high-voltage positive electrode of DC/DC changer, the high voltage negative of DC/DC changer is connected with the contact input end of negative pole main relay, and the contact input end of negative pole main relay is connected with the negative pole of electrokinetic cell.
The present invention has the productive costs that can reduce electronlmobil, reduces the own wt of electronlmobil, saves the installing space of electronlmobil, thus improves the advantage of electronlmobil stability in use.
Accompanying drawing explanation
Fig. 1 is control principle schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, the present invention is that electronlmobil utilizes DC/DC changer ignition initiation devices, comprise DC/DC changer 4, the positive pole of electrokinetic cell 1 is connected with the contact input end of positive pole main relay 5, the contact input end of positive pole main relay 5 is connected with one end of HVDC fuse 2, the other end of HVDC fuse 2 is connected with the input end of battery isolator control 3, the mouth of battery isolator control 3 is connected with the high-voltage positive electrode of DC/DC changer 4, the high voltage negative of DC/DC changer 4 is connected with the contact input end of negative pole main relay 6, the contact input end of negative pole main relay 6 is connected with the negative pole of electrokinetic cell 1.
Principle of work of the present invention is as follows: before vehicle launch, first closed battery isolator control 3, the input high-voltage positive electrode of DC/DC changer 4 is communicated with, DC/DC changer 4 is started working, export DC12V power supply and for vehicle ignition switch and other need the electrical part of normal electricity to provide DC12V power supply, closes ignition switch also presses the operation of electronlmobil operating process, and each system of vehicle starts normal operation.
When vehicle long-time parked time, power cut-off main supply switch 3, makes the input high-voltage positive electrode of DC/DC changer 4 cut off, and DC/DC changer 4 quits work and stops exporting DC12V power supply.
The present invention is provided with battery isolator control 3, by the unlatching closed procedure to battery isolator control 3, realize cutting off the connected sum of DC/DC changer 4 high tension supply, thus realize the output of DC/DC changer 4 and stop exporting DC12V power supply, finally realize electronlmobil utilize DC/DC changer to cancel technical scheme that vehicle-mounted lead-acid storage battery carries out ignition trigger.
