Background technology
Along with industrial expansion, the continuous atrophy of traditional energy, resource is hard to carry on.Image-stone oil is this close with daily life
Relevant energy major part is from import, it is easy to affected by extraneous factor, as second time the war in Iraq makes whole world stone
Oil is in short supply, and OPEC is also constantly raising crude oil price for the interests safeguarding oneself.And the oil reserve amount of China
And few, so oil price volatility is serious, five yuan of epoch just step out several days and have just rapidly returned back to the hexa-atomic epoch.The most national sustainable
The proposition of development strategy and the lifting of environmental consciousness, electric motor car arises at the historic moment under such market environment.It is with renewable energy
Source electric energy is as drive energy, and electric motor car is because occupy the most excellent on the price advantage of one-time consumption and subsequent consumption
Gesture, and it there are convenient and swift, energy-conserving and environment-protective, occupation of land space is little and does not the most substantially have the excellent of noise pollution

Steal, and the work such as warning can not be carried out, and mechanical lock is easily pried open.Particularly cannot withstand a single blow under hydraulic tongs at all,
Make lockset alarm can only prevent to a certain extent stealing and to delaying the time stolen.And antitheft the touching of wireless remote control type
Make a start and the most single, most only vibration sensors, and can not be by the synchronizing information of electric motor car to car owner.A lot
In the case of, be still easy to allow unprincipled fellow go smoothly, as noisy environment or thunderstorm when, electric motor car be easy to by
External environment is triggered reports to the police, and the most often no one can notice the situation of electric motor car, if at this moment someone keeps a close watch on that
Your electric motor car, just can easily go smoothly in two minutes.So, as this type of electronic type is antitheft can not meet the most far away antitheft
Requirement.Abroad, very many car owners can select GPS geo-location system to carry out being put into protection to the love car of oneself.Example
The 10 Electrified Moped Scooters released such as vanmoof company, are the most just built among vehicle frame by battery, have
Effect prevent the stolen risk of battery, and at car built with GPS module.Even if stolen, also can be known oneself by the Internet
Car at which, with the help of police, recover vehicle.Owing to installing a cost of GPS, GSM, GPRS, to exceed other antitheft
Mode is a lot, but also needs user to pay follow-up service expense, and this makes major part electric motor car car owner be reluctant to accept, and still can not
Commonly use, so they are less in the market prospect of electric motor car.
During realizing the present invention, inventor finds that at least there is major part electric motor car user in prior art uses
The alarm etc. being still that mechanical anti-theft and unidirectional anti-theft modes the antitheft mode of electric motor car safety cannot be effectively ensured simultaneously,
