Specific embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical Novel protected range.

The electric power controller of the utility model discloses a kind of pure electric vehicle logistic car with fast charge, which is characterized in that such as Shown in Fig. 1, it includes key switch 1, vehicle wakes up relay 2 and charging wakes up relay 3, and the vehicle wakes up relay 2 Including first switch K1 and first coil T1, it includes second switch K2 and the second coil T2 that the charging, which wakes up relay 3, and first Coil T1 and the second coil T2 respectively drives first switch K1 and second switch K2 by electromagnetic induction and is closed.

The key switch 1 of vehicle is altogether equipped with 3 grades: Off, On, Start, according to the functional character of existing system, to fast charge The function of related controller is defined as: high-tension battery Management Controller 6 is responsible for judging 7 end of fast charge stake and the charge condition of itself, Entire car controller 4 is responsible for judging that whole vehicle state, and control cooling water pump turn the cooling of low pressure controller 5 to high pressure, and high pressure turns low pressure Controller 5 is responsible for giving low pressure accessories.

The positive KL30 of the input terminal access automobile batteries of the key switch 1, the end Start of the key switch 1 are logical It crosses enabling signal line 11 to connect with entire car controller 4, the end On of the key switch 1 and electric machine controller 12, car body controller 13 and instrument controller 14 connect, the end On of the key switch 1 connect with the first wake-up signal line 8, and first wake-up is believed Number line 8 is connect with one end of first coil T1, the other end ground connection of the first coil T1, the input terminal of the first switch K1 It being connect with the positive KL30 of automobile batteries, the output end of the first switch K1 is connect with the second wake-up signal line 9, and described second Wake-up signal line 9 is connect with the input terminal that entire car controller 4, high pressure turn low pressure controller 5 and high-tension battery Management Controller 6, The second wake-up signal line 9 is also connect with the output end of second switch K2, input terminal and the automobile electricity of the second switch K2 The positive KL30 connection in pond, the high-tension battery Management Controller 6 are grounded by the second coil T2, the high-tension battery management control Device 6 processed is connect by third wake-up signal line 10 with fast charge stake 7.

When driver operates key switch 1 from Off grades to Off grades non-, the first wake-up signal line 8 is drawn high, to wake up non- The relevant controller of fast charge, such as car body controller 13, instrument controller 14, electric machine controller 12, above controller is worked normally； Meanwhile first wake-up signal line 8 relay 2 waken up by vehicle draw high the second wake-up signal line 9, wake up the relevant control of fast charge Device, at this point, all controllers are all waken up, specific as shown in Fig. 2, entire car controller 4 is by judging 11 shape of enabling signal line State completes starting.

When driver operates key switch 1 from non-Off grades to Off state, the first wake-up signal line 8 is dragged down, and passes through whole Vehicle wakes up relay 2 and drags down the second wake-up signal line 9.All controllers are according to wake-up signal threadiness state, into suspend mode.

As shown in Fig. 3, when fast charge, at Off grades, the holding of the first wake-up signal line 8 drags down 1 state of key switch, non-fast Filling relevant controller will not be waken up, and external charging pile is drawn high by third wake-up signal line 10, to wake up high-voltage electricity Pond Management Controller 6, the judgement of high-tension battery Management Controller 6 need to charge, then draw high second by charging wake-up relay 3 and call out It wakes up signal wire 9, to wake up entire car controller 4 and high pressure turns low pressure controller 5, completes fast charge.

Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new The range of each embodiment technical solution of type.
