摘 要:根據(jù)車(chē)載動(dòng)力電池和超級(jí)電容各自的特點(diǎn),為普通電動(dòng)車(chē)加裝了超級(jí)電容驅(qū)動(dòng)裝置,實(shí)現(xiàn)動(dòng)力電池與超級(jí)電容混合驅(qū)動(dòng)的模式。根據(jù)車(chē)輛實(shí)際運(yùn)行時(shí)的功率變化特性,建立模擬實(shí)驗(yàn)方法,對(duì)純電池驅(qū)動(dòng)和混合驅(qū)動(dòng)兩種狀態(tài)進(jìn)行了實(shí)車(chē)運(yùn)行的對(duì)比測(cè)試。結(jié)果表明超級(jí)電容可以提高車(chē)載電源系統(tǒng)的功率密度和放電效率,延長(zhǎng)續(xù)駛里程,降低電池發(fā)熱程度,延長(zhǎng)其實(shí)際使用壽命等。利用超級(jí)電容驅(qū)動(dòng)裝置可輕松獲得優(yōu)于純電池驅(qū)動(dòng)的功率密度。未來(lái)車(chē)載動(dòng)力電池可專(zhuān)注于發(fā)展提高能量密度和循環(huán)使用壽命。

Abstract: According to the characteristics of car battery and ultracapacitor, the ultracapacitor driving module was added to a electric vehicle, together with battery constituting a hybrid drive mode. Based on the power variation characteristic when vehicle running, a simulation method was established to compare the pure battery-powered test and hybrid driving test. The results show that the ultracapacitor can improve the power density and discharge efficiency of vehicle power supply system, extend the vehicle miles traveled, reduce battery temperature rise, extend battery cycle life, etc. The use of ultracapacitor can easily get higher power density than pure battery-driven. The car battery development can be focused on the improvement of energy and cycle life in the future.
Key words: ultracapacitor; hybrid drive; comparison test; voltage characteristics
