Principle of work:
Lithium cell power supply pins to the microcontroller on the built-in fender of lithium cell by adopting the mobile phone locking function key that APP is housed by the utility model, discharge loop by lithium cell disconnects, cut off lithium cell supplying power for outside, thus reach the effect that the Circuits System built-in to lithium cell lock, even if make electric car have battery pack also cannot normally start, simultaneously can also by the microcontroller on the intelligent locking key remote control lithium cell on mobile phone, microprocessor control detecting unit constantly detects the outgoing current of lithium battery protection board circuit, once electric current occurs that unusual fluctuation (as electric current is greater than 2A suddenly) pins battery immediately, discharge loop by lithium cell disconnects, cut off lithium cell supplying power for outside, then through again reopening discharge loop after a period of time, and detecting unit detects the outgoing current of lithium battery protection board circuit again, so constantly circulate after noting abnormalities, until the unlocking signal receiving mobile phone can de-preservation state.Vibrations annunciator is provided with battery pack while of this, when after opening anti-theft function, battery pack moves as run into or vibrations just start to report to the police, microcontroller contacts mobile phone by signal transceiver simultaneously, the coordinate information that simultaneously GPRSGPS module can send battery at set intervals notifies user side, and user can recover battery pack fast according to coordinate information.
The beneficial effects of the utility model:
The utility model adopts two kinds of antitheft modes: the first is for vehicle itself is without any anti-theft measure, but burglary-resisting installation and tracing equipment are set in power pack, safest mode when this is direct power-off, can reach like this and prevent stealing power pack and also can antitheft and tracing and positioning recover.The second is that vehicle itself is also provided with burglar alarm; the timely like this intelligence that opens is locked; the burglar alarm of battery-driven car itself still can normally work; once detect that motor has the sign of startup under intelligent anti-theft pattern; the output of battery built-in circuit can be closed; forbid that battery-driven car travels, reach the object of duplicate protection.The voltage levels of interpretation battery, vehicle can travel or stationary condition, control, to the state of consumer supply electric energy, to carry out over voltage or under-voltage protection, protect consumer and battery by this.The utility model improves li-ion cell protection and theftproof performance, particularly lithium cell safety performance on a vehicle, is of the present utility modelly widely used in vehicle anti-theft.
