摘　　要：目前电动汽车电池在续航里程、充电效率、安全性等方面存在不足,所以不能完全满足人们的用车需求,阻碍了电动汽车产业的进一步发展。为保证电动汽车电池的性能及用户的充电体验,要求电池具有较高的能量密度保证其续航能力,同时具有良好的高、低温充放电性能,以提高充电效率和充电时间。此外,为了减少交通事故引发的短路、热冲击、爆炸等安全问题,需要对电池的安全性提出更高的要求。笔者主要梳理了电动汽车面临的问题及性能,并提出了电动汽车电池的日常维护和保养建议。At present,electric vehicle batteries are insufficient in terms of driving range,charging efficiency,safety and other aspects,which cannot fully meet people's vehicle needs,hindering the further development of electric vehicle industry.In order to ensure the performance of EV batteries and users'charging experience,the battery is required to have a high energy density to ensure its endurance,and has good high and low temperature charging and discharging performance to improve charging efficiency and charging time.In addition,in order to reduce traffic accidents caused by short circuit,thermal shock,explosion and other safety problems,need to put forward higher requirements for the safety of batteries.The author mainly reviews the problems and performance of electric vehicles,and puts forward suggestions on the daily maintenance and maintenance of electric vehicle batteries.
