Enabling fast charging – Vehicle considerations

Journal Article · · Journal of Power Sources
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 improve the range that BEVs can travel. While the range that BEVs can travel on a single recharge is improving, the rate at which these vehicles can be recharged is still much slower than conventional internal combustion engine vehicles. To achieve comparable recharge times we explore the vehicle considerations of charge rates up to 350 kW. This 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 maybe required. This substantial increase in the charging rate is expected to create technical issues in the design of the battery system and the vehicle electrical architecture that must be resolved. This work will focus on the battery system thermal design and total recharge time to meet the goals of implementing higher charge rates as well as the impacts of the expected increase in system voltage on the components of the vehicle.
