摘　　要：电动汽车作为一种以车载电源为源动力驱动的新型汽车,是一种具有着良好发展空间的环保交通工具。作为这种绿色交通工具发展的前提基础,充电设施的完善、电力部门和电力企业对充电计量的规范标准化就显得尤为重要。而做好充电计量仪表的校准工作更是让充电能够规范标准化的关键。利用时分割脉冲调宽技术可以提高高精度基准电压的精度确保校准仪器时稳定度以及准确度。Electric vehicles as a kind of power-driven vehicle power supply as the source of the new model car, is a kind of a good space for development of environmentally friendly transport. To complete charging facilities,, charge measured of the power sector and electricity companies on standardized norms is very important. They are the basis for the development of green transport. The key of charging to specification standardizes is to make charge measuring instrument calibration more better. With the time division pulse width modulation technology, it can improve the precision reference voltage to ensure the instrument calibration stability and accuracy.
