Description
Technical field
The utility model relates to electric vehicle engineering field, and particularly a kind of air conditioning switch of electronlmobil controls pre-fill system.
Background technology
The air-conditioning electric capacity of electronlmobil and switch contact and electric machine controller MCU etc. are connected in parallel on high-voltage power-line.Carry out preliminary filling to electric machine controller electric capacity after electronlmobil powers on, air conditioning switch contactless switch closes, and carries out preliminary filling to air-conditioning electric capacity; Under electronlmobil, after electricity, air conditioning switch contactless switch disconnects.Wherein, vehicle control unit controls air conditioning switch contactless switch is enable.The prior art is after electronlmobil powers on, as electric machine controller electric capacity etc. has completed preliminary filling, now as shorter to the time gap again powered on after electricity under electronlmobil, closed air conditioning contact, because the electric capacity of electric machine controller is larger, not there is active discharge function, electric machine controller electric capacity can give air-conditioner controller capacitor charging at once, because air-conditioning resistive fuse value is very little, recharge the excessive air-conditioning fuse that causes of electric current in circuit to burn, it is enable that entire car controller cannot control air conditioning switch again.
Summary of the invention
The technical problems to be solved in the utility model, is that the air conditioning switch providing a kind of electronlmobil controls pre-fill system; Utilize electric automobile air conditioner precharging circuit, produce voltage by the Current Voltage of air-conditioning fuse and MCU capacitive strike when electronlmobil is powered on equal, ensure the normal work of air-conditioning fuse.
The utility model is achieved in that a kind of air conditioning switch of electronlmobil controls pre-fill system, and this system comprises entire car controller, and system also comprises electric automobile air conditioner control circuit and electric automobile air conditioner precharging circuit; Described entire car controller, electric automobile air conditioner control circuit, electric automobile air conditioner precharging circuit connect successively; Described electric automobile air conditioner control circuit comprises: fuse fu2, air conditioning contact k3 and air-conditioning; Described fuse fu2, air conditioning contact k3, air-conditioning are connected; Described electric automobile air conditioner precharging circuit comprises: preliminary filling resistance R2 and contactless switch k4; Described preliminary filling resistance R2 and contactless switch k4 is parallel to the two ends of air conditioning contact k3 and fuse fu2 after connecting.
Further, described electric automobile air conditioner control circuit also comprises: resistance R1, contactless switch k1, contactless switch k2, MCU and fuse fu1; Described resistance R1 and contactless switch k1 is in parallel with contactless switch k2 after connecting, and described MCU is connected with contactless switch k2, fuse fu1 respectively, is parallel to MCU two ends after the series connection of described fuse fu2, air conditioning contact k3, air-conditioning.
The utility model has the advantage of: the utility model solves the air-conditioning safety fuse cutout of electronlmobil when the short period power-on and power-off of electronlmobil interval; because electric machine controller MCU electric capacity recharges the excessive and problem that fuses of electric current; protection air conditioning switch control system, makes the normal enable control air-conditioning of entire car controller energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Refer to shown in Fig. 1, a kind of air conditioning switch of electronlmobil controls pre-fill system, and this system comprises entire car controller (not shown), and system also comprises electric automobile air conditioner control circuit and electric automobile air conditioner precharging circuit; Described entire car controller, electric automobile air conditioner control circuit, electric automobile air conditioner precharging circuit connect successively; Described electric automobile air conditioner control circuit comprises: resistance R1, contactless switch k1, contactless switch k2, MCU, fuse fu1, fuse fu2, air conditioning contact k3 and air-conditioning AC; Described resistance R1 and contactless switch k1 is in parallel with contactless switch k2 after connecting, and described MCU is connected with contactless switch k2, fuse fu1 respectively, is parallel to MCU two ends after described fuse fu2, air conditioning contact k3, air-conditioning AC series connection; Described electric automobile air conditioner precharging circuit comprises: preliminary filling resistance R2 and contactless switch k4; Described preliminary filling resistance R2 and contactless switch k4 is parallel to the two ends of air conditioning contact k3 and fuse fu2 after connecting.
This principle of work is: after electronlmobil powers on, the contactless switch k4 of vehicle control unit controls air-conditioning preliminary filling closes, preliminary filling is carried out to the electric capacity of electric machine controller MCU electric capacity and air-conditioning, electric capacity preliminary filling completes, electric automobile air conditioner precharging circuit voltage is equal with electric machine controller MCU voltage, and (under being included in battery-driven car, the electricity rear interval short period powers on, electric machine controller electric capacity recharges situation to air-conditioning electric capacity) time, vehicle control unit controls air conditioning contact k3 closes, and controls air-conditioning enable.
The utility model solves the air-conditioning safety fuse cutout of electronlmobil when the short period power-on and power-off of electronlmobil interval; because electric machine controller MCU electric capacity recharges the excessive and problem that fuses of electric current; protection air conditioning switch control system, makes the normal enable control air-conditioning of entire car controller energy.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
