Detailed description of the invention
As shown in Figure 1, electric delay control system under a kind of pure electric automobile car load described in the utility model embodiment, comprise storage battery 1, entire car controller 2, electric machine controller 5, battery management system 6 and source switch 3, described storage battery 1 is connected with delay control circuit 4, described delay control circuit 4 is connected with entire car controller 2, electric machine controller 5 and battery management system 6 respectively, and described entire car controller 2 connects source switch 3; Between described entire car controller 2 and electric machine controller 5 and battery management system 6, be connected by CAN bus 7.
By delay control circuit 4, anodal the storage battery of car load 1 electricity 9 is become to ON_OUT 8, power to electric machine controller 5, battery management system 6 by ON_OUT 8.When detecting car load source switch 3, entire car controller 2 enters OFF shelves, entire car controller 2 sends to electric machine controller 5, battery management system 6 by CAN bus 7 by the OFF state of car load source switch 3, electric machine controller 5 starts to carry out the backup preservation work of current data, and detect temperature and the temperature rising state of each subsystem, assessment postpones the time demand of power-off, and time demand is occurred to entire car controller 2 by CAN bus 7.Battery management system 6 starts to carry out the backup preservation work of current data, and detects temperature and the temperature rising state of each subsystem, and assessment postpones the time demand of power-off, and time demand is occurred to entire car controller 2 by CAN bus 7.
Entire car controller 2 starts backup and save data, wait for the time demand that electric machine controller 5 and battery management system 6 feed back simultaneously, by the fixed-time control unit of entire car controller 2, timing receives the information that under the delay that electric machine controller 5 and battery management system 6 send by CAN bus 7, electricity has been worked, entire car controller 2 confirms that electric machine controller 5 and battery management system 6 have all possessed lower electric condition, the lower electric dead work of simultaneously confirming self all completes, entire car controller 2 is controlled lower 4 times electricity of electric delay control circuit, makes ON_OUT8 be output as zero.
As shown in Figure 2, in the time that key S1 gets to ON shelves, power supply makes optocoupler U2 conducting by diode D2 and resistance R 3, and the level of optocoupler output pin and resistance R 5 junctions becomes low level; Another power branch passes through the supply electrical input of diode D1 to flash source switch chip Q1 simultaneously, in the time of optocoupler conducting, the control end A of flash source switch chip Q1 also becomes low level, power supply by Q1 to power conversion chip U4, U4 starts working, its mouth OUT exports the power input VCC of CPU to, and output is for the CPU required voltage of working, and CPU starts working.After the normal work of CPU, when CPU pin, IO1 detects after ignition signal, controls IO2 and makes its output high level, controls optocoupler U3 conducting, also can make the control end A of flash source switch chip Q1 become low level.
In the time that key is got to OFF shelves, due to conducting work of optocoupler U3, the control end A of flash source switch chip Q1 is still low level, so flash source switch chip Q1 normally works, thereby ensure that CPU can normally work, now CPU detects that IO1 becomes low level from high level, learn and carry out power-off action, in the time that entire car controller 2 detects that whole vehicle state has all returned to zone of reasonableness, CPU controls IO2 and makes its output low level, control optocoupler U3 cut-off, thereby flash source switch chip Q1 is also quit work, reach the object of delay cut-off, so far, complete the breaking time-delaying work of entire car controller 2, prevent that whole vehicle state is unreasonable in the time of power-off, improve the safety of car load.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
