As for the details of the system designed by researchers, which one is CORRECT?

参考解析：

细节理解题。根据第五段倒数第二句“If the system is aware in advance that a recharging station will be used as part of the trip (which might be arranged by booking one via the vehicle’s information screen) it can spread the use of electric power throughout the journey, to maximum advantage, knowing when the battery will be topped up.”如果系统提前知道路上可以充电（这能通过在车上的信息屏幕进行预定，然后提前安排），它能够在旅途中均衡使用电能，在知道电池在何时能够被充满的前提下，达到最大利用率；可知B项表述正确。根据最后一段第一句“Dr Qi and his colleagues now hope to work with a carmaker to test the algorithm on real roads.”可知D项错误；根据最后一段最后一句“If all goes well, and their system proves able to cope with the nightmares of commuting in southern California, they will not be left stranded on the hard shoulder”（如果一切顺利，他们的系统将被证实能够解决南加州上下班路段的难题，那么也将不会出现车辆拥堵的情况了）可知C项错误；根据第四段的内容可知研究人员决定研发一款不依赖于目的地位置的系统，即不依赖导航，A项错误。故选B。
