国庆假期期间，全国高速公路新能源汽车充电需求激增，部分服务区采取了充电至80%强制离场的管理措施。110月1日0时至10月3日24时，全国高速公路新能源汽车充电次数达到296.86万次，较去年同期增长48.41%，充电总量为7161.93万千瓦时，同比增长49.39%。1
针对"八分饱"充电是否影响电池寿命的疑问，国网专家解释称这种做法对锂电池无害。1电池充电过程中，0至80%属于高效快充阶段，而80%之后进入涓流慢充模式，剩余20%电量所需充电时长基本等同于前80%的耗时。1实施80%强制离场规定的主要原因是，涓流慢充模式耗时长且占用桩位资源多，在假期高峰期会影响充电效率。1
为缓解充电压力，相关部门建议车主提前规划路线并错峰充电。1充电高峰时段集中在10月5日11时至21时和10月6日10时至22时，车主应尽量避开这些时间段。1秦滨高速河北段乐亭服务区、唐海服务区等9处服务区成为国庆特别繁忙区域。1车主可通过"e路畅通"小程序实时查询充电桩的空闲状态，以便选择最优的充电地点和时间。1
During China's National Day holiday period, demand for electric vehicle charging on national highways surged dramatically, with some service areas implementing policies requiring drivers to vacate charging stations once their batteries reach 80% capacity.1 From October 1 at midnight through October 3, the nation's expressways recorded 2.97 million charging sessions, a 48.41% increase compared to the same period last year, with total energy delivered reaching 71.62 million kilowatt-hours, up 49.39% year-over-year.1
According to experts from the State Grid, charging to 80% poses no harm to lithium batteries, as the process transitions into a slow trickle-charging mode after that threshold, which is substantially slower and occupies charging infrastructure for extended periods.1 The high-efficiency fast-charging phase spans from zero to 80% capacity, while the remaining 20% takes roughly as long to charge as the initial 80%.1
To manage holiday congestion, authorities identified nine particularly congested service areas on expressways, including the Leuting and Tanghai rest stops on the Qin-Binhai Expressway in Hebei.1 Drivers are advised to stagger their charging times and plan routes ahead, specifically avoiding peak periods on October 5 from 11 a.m. to 9 p.m. and October 6 from 10 a.m. to 10 p.m.1 Those seeking real-time information can use the "E-Road Smooth Travel" mini-program to check charging station availability.1
