The specific embodiment
Referring to Fig. 1, controller 1 is connected with vehicle-mounted detecting system 10; Controller communications reception port is connected with car-mounted computer 11 communication output interfaces; Three branch roads of controller by pull up circuit 2 respectively with automobile power cell 3 anodal are connected with load be connected; Three branch roads of described pull up circuit wherein branch road connect successively the IGBT6 gate pole G that powers on, the IGBT collecting electrode C that powers on, current-limiting resistance 7, load, negative pole relay 5, automobile power cell 3 negative poles; Another branch road connects lower electric IGBT8 gate pole G successively, lower electric IGBT collecting electrode C, access load; Article three, branch road is by main relay 9 access loads; Positive source is connected with upper IGBT emitter E, main relay, lower electric IGBT emitter E successively.
Checking system comprises that current sensing means, voltage check device are or/and temperature-detecting device; Communication facilities is car-mounted computer; Power supply is automobile power cell.
Referring to Fig. 2, Fig. 4, high voltage system is by receiving the order that powers on of high pressure that car load sends with the communication interface of entire car controller.Power on order proceed to the flow process that powers on if receive.At first the temperature of each vital part be to detect, main relay, negative pole relay, the IGBT that powers on, lower electric IGBT, current-limiting resistance comprised.Because in the process that powers on, the excessive fault of cal val easily appears in these elements.The temperature that detected these elements before powering on does not allow to power on when excess Temperature, simultaneously to whole-control system newspaper temperature anomaly fault.If the temperature of each temperature spot is all in normal scope continue to carry out the flow process that powers on.Temperature detection prevents that component wear from being an innovative point of this patent.Then, negative pole relay closes, time-delay t1; Then, the conducting IGBT that powers on charges to the electric capacity of load, and individual lower limit is arranged during this period of time, is set as t2.T2 is after the time in time-delay, and control system detects automobile power cell voltage V1 and high voltage dc bus voltage is the voltage V2 of load end.If V1-V2 less than permissible value (being set as V), carries out next flow process, otherwise continue to wait for.When V1-V2＜V, the voltage difference at expression main relay two ends is very little, high-voltage arc can not occur, at this moment can closed main relay.Then, time-delay t3.Disconnect at last the IGBT that powers on, complete power up.In Fig. 4, MAIN is main relay, and REL is the negative pole relay, and the IGBT that powers on uses when high pressure powers on, lower electric IGBT under high pressure when electricity use, t1=100ms in Fig. 3; T2=200ms; T3=500ms.
Referring to Fig. 3, Fig. 5, when automobile power cell high pressure connection control system receives under the high pressure that whole-control system sends the electricity order, begin to carry out electric current journey under high pressure.At first, electric IGBT under conducting disconnects main relay after time-delay t4, and at this moment, electric current flows through from lower electric IGBT, and electric current does not have variation sharply on main relay, so main relay can not damage.In Fig. 5, MAIN is main relay, and REL is the negative pole relay.T4=100ms in Fig. 5; T5=200ms; T6=200ms.
Main relay disconnects t5 and disconnects lower electric IGBT after the time.Due to, the characteristic of IGBT itself, the break-make of instantaneous large-current can not impact device itself.At last, t6 is after the time in time-delay, and lower electric current journey finishes.
