(2) detection of electrical leakage module of the present utility model comprises the current detection module for detecting electrostatic belt leakage current and the voltage detection module for detecting electrical leakage voltage between vehicle body and electric powered motor power cathode.The utility model adopts leakage current and voltage two kinds of detection modes.Under the state of body shell electric leakage, by electrostatic belt ground connection, once shell occurs that electric leakage is unexpected, will inevitably produce leakage current by electrostatic belt access the earth, the electric current that storage battery positive pole will inevitably be made like this to export occurs different with inflow storage battery cathodal current, and differential section flows into the earth, in vehicle travel process, may occur that broken string electric current exists, as long as there is leakage current, can differentiate that vehicle leaks electricity; Voltage detecting, namely the voltage between vehicle body and electric powered motor power cathode, once there is electric leakage, damaging appears in the electrostatic belt of vehicle itself, then cannot detect electric leakage by the mode of leakage current, the existence that superpotential mode detects leak current fault can only be led to, as long as the voltage that has namely between vehicle body and electric powered motor power cathode exists, so just can determine that leak current fault appears in electronlmobil.
(3) if vehicle remains static, namely the speed of a motor vehicle is zero, then main control unit exports door lock and opens control signal, exports delay cut-off control signal after the 400ms of time delay simultaneously; If vehicle is in motoring condition, and the speed of a motor vehicle is higher than 3km/h, then, after waiting for that the speed of a motor vehicle is brought down below 3km/h, main control unit exports door lock and opens control signal, exports delay cut-off control signal, disconnect electrical source of power after the 400ms of time delay simultaneously.
(4) storage battery storehouse deformation-sensor is fixed on the shell of high pressure storage battery storehouse, and after storage battery storehouse deformation-sensor detects the distortion in storage battery storehouse, meeting output signal is to main control unit, and warning reminding driver and conductor take care.
(5) malfunction coefficient alarm module is arranged near chaufeur, and after there is alerting signal, chaufeur can understand the accident problem occurred easily, takes corresponding emergency schedule, guarantees the personal safety of driver and conductor.
(6) after main control unit receives electric leakage signal, export sound and light alarm signal, provide sound and light alarm by combined aural and visual alarm to combined aural and visual alarm, the exportable signal of combined aural and visual alarm is to main control unit simultaneously, to confirm the state of self.
(7) power-off restoration switch has lasting big current make-break capacity, its reliable in action, controls electric current little, and the electric current of sampling 100ma gets final product the disconnection that failure-free controls electrical vehicular power power supply, substantially increases the reliability of internal cell; When after the releasing emergency state, person skilled determines not have that Keep Clear-High Voltage, when also there is not high pressure electric leakage, electrical vehicular power power supply can be connected by manual reset, recover the performance of vehicle, namely save vehicular rescue maintenance cost, also ensure that the safety of vehicle and personnel.
(8) main control unit of the present utility model and combined aural and visual alarm are powered the low potential source that can adopt and provide for oneself, to ensure in emergency situations, even if external low-voltage direct electric fault power-off, and still can failure-free stable operation; This low potential source can use the electrical source of power of electronlmobil itself to charge simultaneously, to ensure that low potential source is in significant condition all the time.
(9) in order to extend time of fire alarming, the utility model can carry out the quantity of intelligent determination combined aural and visual alarm work according to the dump energy situation of low potential source: when there being external low-voltage direct low pressure, and four combined aural and visual alarm continue to report to the police simultaneously; Also the low potential source provided for oneself can be used to power for main control unit and combined aural and visual alarm, when electric power detection module detects that the electricity of low potential source only remains 60% ~ 40%, main control unit only controls two combined aural and visual alarm and exports audible alarm, to save electricity, when the dump energy of low potential source is less than 40%, main control unit only controls a combined aural and visual alarm and exports audible alarm, when dump energy lower than 20% time, then close the audible alarm of all combined aural and visual alarm, only to glimmer warning, until electricity exhausts.When using the low potential source provided for oneself, sustainable more than 4 hours of warning time length of the present utility model.
