Described VCU is also connected with two high voltage connectors.
Further, this utility model also includes accumulator, and described battery positive voltage is connected with VCU, DC/DC and cold preservation unit, minus earth；
Described DC/DC, DC/AC, relay, high voltage connector wherein one end is ground connection respectively.
Yet further, described relay is also connected with the low pressure accessory power supply of refrigerator car with DC/DC.
What deserves to be explained is in Fig. 1, J1 is relay, and K1, K2 are high voltage connector, and 1023,1024,8101,1809,8615,1601 is wire size, and VCU is entire car controller.
Under this utility model charged state, cold preservation unit by full-vehicle control logic is: under charged state, charging gun mesolow accessory power supply (hereinafter referred to as ACC) has electricity, makes unit allocation panel to work.When cold preservation unit panel is opened, VCU receives the enabling signal of 1601, controls 1203,1204 and allows catalyst turn on, and DC/DC connects high-tension electricity with cold storage and air conditioner DC/AC.By CAN, entire car controller and DC/DC, DC/AC carry out communication.Starting DC/DC and DC/AC and enter normal operating conditions, DC/DC exports 24V power supply work cold preservation unit low pressure use, and DC/AC inversion three-phase electricity is for cold preservation unit high pressure.After breaking down, VCU, by 1809 control relays, allows cold storage and air conditioner control panel and cold preservation DC/AC quit work.
This utility model compared with prior art, has the following advantages and beneficial effect:
This utility model can realize electronic refrigerator wagon and open refrigerating function in the charge state.
Accompanying drawing explanation
Fig. 1 is system block diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As it is shown in figure 1, a kind of refrigerator car electric control system, including cold storage and air conditioner control panel, cold preservation unit, VCU, DC/DC, DC/AC, power battery pack, relay, high voltage connector；
Wherein, described cold storage and air conditioner control panel, cold preservation unit, VCU are connected with relay respectively；
Described VCU also carries out communication with DC/DC, DC/AC, cold storage and air conditioner control panel by CAN；
Described DC/DC, DC/AC are also connected with cold preservation unit；
Described power battery pack one end is connected with DC/DC and DC/AC respectively, the other end by two high voltage connectors respectively with DC/DC and DC/AC；
Described VCU is also connected with two high voltage connectors.
Specifically, this utility model also includes accumulator, and described battery positive voltage is connected with VCU, DC/DC and cold preservation unit, minus earth；
Described DC/DC, DC/AC, relay, high voltage connector wherein one end is ground connection respectively.
It addition, described relay is also connected with the low pressure accessory power supply of refrigerator car with DC/DC.
What deserves to be explained is in Fig. 1, J1 is relay, and K1, K2 are high voltage connector, and 1023,1024,8101,1809,8615,1601 is wire size, and VCU is entire car controller.
This utility model concrete implementation method is as follows:
1, ACC comes from charging gun existing power supply, and ACC energising after car load enters normal charging condition, cold storage and air conditioner control panel connects low tension with cold storage and air conditioner DC/AC.
2, after carrying out cold storage and air conditioner open operation above cold preservation control panel, cold preservation control panel output enabling signal, after this signal receives enabling signal to VCU, VUC, control high voltage connector by 1203, allow power battery pack power supply lead to DC/DC.By CAN and DC/DC communication, start DC/DC and first allow unit fan for low tension.Then, control high voltage connector by 1204, allow power battery pack power supply lead to DC/AC.By CAN and DC/AC communication, starting DC/AC to unit motor for high-tension electricity, cold preservation unit starts normal operation.
3, control cold preservation unit DC/AC by CAN, VCU, cold preservation unit is controlled (motor speed, power etc.).Meanwhile, when cold preservation unit DC/AC breaks down (short circuit, overload etc.) and signal can be passed to VCU by CAN by cold preservation control panel signal (fault, temperature etc.).Breaking down, VCU is by the start and stop of 1809 control cold preservation hole air-conditionings, or closes closing down of DC/DC, DC/AC control cold storage and air conditioner by CAN, and car load is by instrument display alarm simultaneously.
What deserves to be explained is, this utility model solves the problem that electronic refrigerator wagon can not open refrigerating function in the charge state.The existing low pressure accessory power supply provided in charging gun is provided, use the existing entire car controller of former car, DC/DC, DC/AC simultaneously, only change partial circuit can realize this function, achieves New function (opening refrigerating function under charged state) when cost is minimum.
According to above-described embodiment, this utility model just can be realized well.What deserves to be explained is; under premise based on said structure design; for solving same technical problem; even if some making on this utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with this utility model, therefore it should also be as in protection domain of the present utility model.
