However, because the price of the two-wheeled electric vehicle is high and the price of the battery is also high, the two-wheeled electric vehicle is easy to be stolen by lawless persons, and a lot of thieves mainly steal the battery pack of the electric bicycle, especially along with the fact that lithium batteries replace lead-acid batteries and are more and more common, the weight of the battery pack is reduced, and the thieves are easier to steal the battery pack. At present, some battery packs are added with GPS positioning and communication modules, although the aim of battery tracking can be achieved, firstly, the cost of the battery pack is increased, and meanwhile, positioning and communication signals are easy to shield, so that the tracking effect cannot be achieved; even more, the owner is mainly stealing whole electric two wheeler directly, directly lifts the two wheeler that has locked to the freight train or in the bread carriage, has caused bigger loss for the vehicle owner, installs GPS and communication equipment additional on whole car and can play the purpose of tracking after stolen, but like this can increase whole car cost to the recollection cost after the vehicle is stolen and leaves the place of accident is also very high. Meanwhile, some anti-theft devices adopt means such as a vibration sensor, and false alarm is easily caused when the vehicle receives vibration of non-theft factors.

In conclusion, the existing product anti-theft design scheme mainly focuses on tracking and positioning stolen battery packs or vehicles through GPS positioning, and cannot effectively give an alarm in time when the theft happens and increases the cost; in addition, the false alarm rate is high by adopting a vibration sensor and the like.

In view of the above, it is desirable to provide an anti-theft device for an electric vehicle to overcome the above-mentioned drawbacks.
