凯迪拉克ELR在2012年北京国际车展上,凯迪拉克宣布首款搭载增程型电力驱动技术的豪华电动轿跑ELR将量产并引入中国市场。凯迪拉克ELR采用的电力驱动系统包括一个功率为16千瓦时的T形锂电池组,一个电力驱动组以及发电发动机。电池组由220多个锂离子电池组成,集成安置底盘上,可以通过连接普通家用电源插座进行充电。当电池能量充足时,ELR实现零油耗、零排放。当电池电量较低时,系统会自动切换至增程行驶模式,发电用的发动机为车辆继续行驶提供电力,确保车辆增加几百公里的续驶里程。这种增程模式消除了人们对于传统电动车电能耗尽后没有后备电能的担忧。
Cadillac ELR At the 2012 Beijing International Auto Show, Cadillac announced the first ELR, a luxury electric coupe equipped with extended-range electric drive technology, to be mass-produced and introduced to the China market. The electric drive system used by the Cadillac ELR includes a T-shaped lithium battery with 16 kWh, an electric drive unit, and a generator engine. The battery pack is made up of more than 220 lithium-ion batteries, integrated on the mounting chassis and can be recharged by connecting to an ordinary household power outlet. When the battery energy is sufficient, ELR achieve zero fuel consumption, zero emissions. When the battery is low, the system will automatically switch to extended range driving mode. The engine for power generation will provide power for the vehicle to continue traveling and ensure that the vehicle increases the driving range by several hundred kilometers. This extended range mode eliminates the concern that traditional electric vehicles will run out of battery power when they run out of power.
