The invention provides freezing protecting liquid for new-energy vehicles. The freezing protecting liquid is used for the low-temperature starting of the new-energy vehicles at the temperature from minus 50 DEG C to minus 18 DEG C and inhibiting ion concentration increasing during high temperature. The freezing protecting liquid is characterized by comprising, by weight, 0.5-5 parts of anhydrous ethylene glycol, 1 part of water and 0.003-0.2 part of nonionic corrosion inhibitor, wherein the nonionic corrosion inhibitor is prepared by the reaction of acid organic matter and alcohol organic matter under high-temperature and alkaline conditions. The freezing protecting liquid can disperse metal ions, neutralize acidity and prevent corrosion, can guarantee the safety operation of the new-energy vehicle in low-temperature and high-temperature environments and can prolong the service life of the new-energy vehicles. 本发明提供了种新能源车的冷冻保护液，用于新能源车在-50～-18℃时的低温启动并在高温时抑制离子浓度的升高，具有这样的特征，按照重量份数计算，包括以下组分：无水乙二醇0.5～5份；水1份；非离子缓蚀剂
