为了实现插电式电池电动汽车（BEV）市场的成功增长，预计需要显著改善电池性能，以增加BEV可以行驶的里程和它们可以充电的速率。虽然BEV单次充电的行驶里程正在提高，但充电速度仍然比传统内燃机车辆的加油速度慢得多。为了实现可比的充电时间，我们探讨了充电率至少为400千瓦的车辆考虑因素。更快的充电预计将显着减轻长途运输的感知缺陷，在人口密集的地区提供替代充电，在那里过夜充电可能是不可能的，并减少在城市内旅行时可能需要计划外充电的范围焦虑。充电速率的大幅提高预计将在电池系统和车辆电气架构的设计中产生必须解决的技术问题。这项工作的重点是车辆系统设计和总充电时间，以满足实施提高充电率的目标，以及这些预期的增加对系统电压和车辆部件的影响。
To achieve a successful increase in the plug-in battery electric vehicle (BEV) market, it is anticipated that a significant improvement in battery performance is required to increase the range that BEVs can travel and the rate at which they can be recharged. While the range that BEVs can travel on a single recharge is improving, the recharge rate is still much slower than the refueling rate of conventional internal combustion engine vehicles. To achieve comparable recharge times, we explore the vehicle considerations of charge rates of at least 400 kW. Faster recharge is expected to significantly mitigate the perceived deficiencies for long-distance transportation, to provide alternative charging in densely populated areas where overnight charging at home may not be possible, and to reduce range anxiety for travel within a city when unplanned charging may be required. This substantial increase in charging rate is expected to create technical issues in the design of the battery system and the vehicle's electrical architecture that must be resolved. This work focuses on vehicle system design and total recharge time to meet the goals of implementing improved charge rates and the impacts of these expected increases on system voltage and vehicle components.
