目前纯电动汽车的技术瓶颈主要是电池,锂离子电池的比能量虽然较铅酸电池与镍氢电池高出很多,但仍然不能满足现代汽车的要求。突出的问题是续驶里程不足(这里强调合理的续驶里程),不适合于长途行驶。在参与工信部电动汽车战略研究课题时,我和中国汽车技术研究中心的尤可为博士就电动汽车的续驶里程和动力性问题做过一些计算。 At present, the main technical bottlenecks of pure electric vehicles are batteries. Although the specific energy of lithium-ion batteries is much higher than that of lead-acid batteries and nickel-metal hydride batteries, they still can not meet the requirements of Hyundai Motor. Prominent issue is the lack of driving range (here emphasize a reasonable driving range), is not suitable for long-distance driving. When participating in the strategic research project of the Ministry of Industry and Information Technology of electric vehicles, I and Dr. Yu Ke of China Automotive Technology Research Center made some calculations on the driving range and power problems of electric vehicles.
