Description
Technical field
The interlocking that the utility model relates to high-tension connector detects, particularly a kind of electric automobile high-voltage interlock fault pick-up unit.
Background technology
For responding the call of sustainable development, new-energy automobile industry develops rapidly.Pure electric automobile and hybrid vehicle represent the developing direction of new-energy automobile.For orthodox car, an important feature of electric automobile is exactly that car load has carried high-pressure system, comprising high voltage components such as charging system, distribution system, accumulator system, power systems.The voltage of high-pressure system is considerably beyond the safe voltage of human body, and causing Danger Electric shock risk for preventing maloperation, guaranteeing to keep in repair safety, high-voltage interlocking loop is absolutely necessary.
Electric motor car carries a lot of high voltage parts, its high-tension connector has all been provided with high-voltage interlocking stitch, be about to disconnect as long as one of them interlocking stitch disconnects car load high tension loop thereupon.Current detection mode is very loaded down with trivial details, once there is interlock fault, each high-tension connector of car load will disconnect to be investigated, and wastes a large amount of time and energy.Increase high-voltage interlocking fault detection system and can simplify malfunction elimination process, accurately location interlock fault generation position.
Summary of the invention
The utility model proposes a kind of electric automobile high-voltage interlock fault pick-up unit, solve when multiple high-tension connector fault, which high-tension connector concrete cannot be determined therefore occur the problem that hinders, the method can simplify malfunction elimination process, and accurately there is position in location interlock fault, it realizes convenient, while minimizing workload, saves the time.
The technical solution of the utility model is achieved in that a kind of electric automobile high-voltage interlock fault pick-up unit, comprise high-voltage interlocking plug-in unit, interlock fault pick-up unit and instrument display, described high-voltage interlocking plug-in unit connects failure detector and instrument display successively by data bus.
As a kind of preferred version of the utility model device, failure detector is made up of impact damper and controller, and high-voltage interlocking plug-in unit is connected with the impact damper of interlock fault pick-up unit, controller successively.
As the further preferred version of the utility model device, impact damper is the device for storing high-voltage interlocking plug-in unit female end level signal.
As the further preferred version of the utility model device, described controller is the device for detecting high-voltage interlocking loop fault generation particular location.
As the another kind of preferred version of the utility model device, described high-voltage interlocking plug-in unit is one another in series, composition high-voltage interlocking loop.
The advantage that the utility model has and good effect are: the utility model device comprises high-voltage interlocking plug-in unit, interlock fault pick-up unit and instrument display, and high-voltage interlocking plug-in unit connects failure detector and instrument display successively by data bus.Data bus is accessed high-voltage interlocking measure loop, simplify the process of malfunction elimination.Car load exists much with the parts of high-voltage interlocking, and when it breaks down, panel board can show particular location automatically, do not need to pull up high-tension connector one by one to investigate, decrease a lot of workload, save the time, and position can occur Accurate Diagnosis fault.Even if there is multiple interlock fault to exist, also can accurately judge position occurs.
