Abstract： In order to solve the problems of shortcomings and deficiencies of the traditional way of the theft of electric vehicles，3G technology was applied to the electric car alarm，positioning systems. Firstly，according to the design requirements， the system structure was established. Then， the hardwares of the system microcontroller circuit，communication circuit，satellite positioning circuit were designed. Finally， the using method of the system was described. The practical results show that the works of the system are accurate and timely，and it improves the chance of electric vehicles back.
