EV has become one of the trends of development in the future；many countries have formulated the development plans for electric vehicles. It is expected that the scale of EV market will be improved greatly before 2020. Comparing with the traditional vehicles，EVs face more risks in structure safety，high voltage safety，fire safety and hydrogen fuel tank blasting safety etc.. Therefore，many countries have established technical standards and regulations to ensure the safety of electric vehicles. This paper introduces the discussions on EV safety technologies and solutions，such as collision protection for high-voltage battery，anti-fire protection of battery，and protection on hydrogen fuel tank etc..
