求翻译：目前电动汽车尚不如内燃机汽车技术完善，尤其是动力电源（电池）的寿命短，使用成本高。电池的储能量小，一次充电后行驶里程不理想，电动车的价格较贵。是什么意思？

Current electric cars as much as a motor car technology, especially power supply (battery) life expectancy, high usage costs. Battery energy storage capacity is small, a single charge range is unsatisfactory, electric car prices more expensive.

The current electric motor is less than perfect technology, in particular, internal combustion engine motor power (battery life expectancy, use the high cost. The small, battery storage capacity after a rechargeable electric vehicles traveling mileage is not ideal, the more expensive.

At present the electric automobile still was inferior the internal combustion engine automobile technology is perfect, in particular power power source (battery) the life is short, the use cost is high.The battery stored energy quantity is small, after a charge goes the course not to be ideal, the e
