国庆假期期间,新能源车出行量显著增加,导致高速服务区充电桩资源紧张,出现排队等候现象。交通运输部预计今年国庆假期新能源车平均出行量是日常的1.8倍。
今天是国庆假期的最后一天。这两天,不少自驾车主开始陆续返程。交通运输部预计,今年国庆假期,新能源车平均出行量是日常的1.8倍,服务区充电桩再次经历大考。为了缓解排队压力,部分高速公路服务区在高峰时段推行充电“八分饱”,也就是当电量达到80%左右,就引导车主结束充电、驶离车位。
这样的举措提高了充电桩周转效率,减少了车主等待时间,获得不少好评。但也有车主担心,一次充不满就要多充几次,这会不会“伤电池”?充电“八分饱”会成为高速服务区的常态吗?
假期进入返程高峰,在湖北交投枣阳北服务区,充电停车区出现了车辆等待情况。为了维持秩序,工作人员在充电区域外围疏导车辆靠边等候,逐车发放充电序号,分轮叫号、按序放行。
排号之外,服务区还采取了一项更受关注的措施:高峰时段,电量充到80%左右,工作人员就会引导车辆驶离充电桩,把位置让给后面的车辆。单车占用时间更短,同一时段能服务更多车辆。车主慕先生说,看着队伍排得很长,没想到很快就轮到自己,实际等候时间比预想短不少。
慕先生:说实话,这个规定我挺能理解的。节假日出行车确实太多,充到80%完全够用,可以到下一站再充。要是每辆车都非充满不可,后面排队的人就得等更久。大家互相迁就一点,效率上来了,对谁都方便。
湖北交投新能源公司副总经理邱新元说,他们对充电桩系统做了设置,遇到车流高峰,充电上限会动态调到80%至85%。这项措施不会一直启用,等车流变少、不再排队,系统就自动恢复,车主可以把电充满。
为什么是“八分饱”?邱新元解释,锂电池特性决定,接近较高电量区间后,同样充进一度电,需要的时间可能更长,80%是一个关键分界点。
邱新元:这个80%的阈值上限不是随意定的。节前我们结合锂电池的充电特性,联合国网电力专家做了测算论证:锂电池在0到80%区间属于高效快充段,充电功率高、补能速度快;电量超过80%后,电池保护机制启动,进入涓流慢充阶段,充电功率断崖式下降,耗时成倍增加。
有车主担心,“充不满”可能意味着要多充几次,这会不会伤电池?邱新元表示:
邱新元:电动车高速行驶后,电池温度往往比较高。如果这时还充得太满,电池更容易发热,反而影响寿命。锂电池的充电寿命并不是按充电次数来算的,最好的做法是浅充浅放,这样并不会对电池造成什么影响。
实际上,多地的高速公路服务区都拿出了类似举措。
交通运输部此前根据历年车联网平台数据,对今年国庆假期高速公路充电需求进行研判,并动态发布充电特别繁忙服务区清单。连霍高速江苏段彭城服务区就在其中。从10月5日中午开始,这里迎来返程充电高峰。服务区负责人张强介绍,高峰时段工作人员会主动劝导车主,在电量达到70%到80%后及时驶离。采取多项疏导措施后,服务区单小时最多可以周转82台充电车辆,桩位周转明显加快。
张强:在车流高峰期,我们和国家电网现场疏导人员主动引导车主充电至70%到80%左右后及时离场,避免长时间满充占位造成车流积压。通过规范、科学引导充电行为,全区单桩周转效率较以往提升了20%左右。
服务区的临时调控手段,能够有效提高充电桩利用效率,而车主科学规划出行同样不可或缺。
张强:为了保障广大车主高效顺畅出行,我们也提醒新能源车辆的驾乘人员理性规划行程,科学错峰出行。主动避开早晚出行高峰时段驶入服务区充电,减少排队等候时间;提前规划行程,依托导航平台实时查询这个沿途服务区充电桩的使用状态,遇到场站饱和,及时绕行至周边低负荷服务区;做好出行前准备,出发前补足车辆电量,预留充足的续航余量,提前制定备选补能方案。

Jaguar's new all-electric luxury four-door GT Type 01 made its world premiere in New York, USA. It is equipped with 1,030 horsepower and 1,365Nm of torque, and can accelerate from 0-100km/h in 3.2 seconds. Pre-sales are open simultaneously in the Taiwan market, with two models, EV1030 and EV1030 Design Vision, starting from NT$6.7 million. There is also a limited edition Chromatic Moments series priced from NT$8.3 million.

Kia's main mid-size SUV Sportage is actively developing a new generation model, which is expected to make its global debut in the third quarter of 2027. The latest test car shows that it adopts a square and sharp style, the body size is enlarged, and it will be equipped with a new generation of TMED-II high-efficiency gasoline-electric hybrid system.

Lexus will launch the RX mid-term facelift model in June next year. It will adopt a new exterior design. The car will introduce a 12.3-inch digital instrument and a 14-inch touch screen. The front passenger seat can be equipped with an optional screen and be equipped with the Arene OS vehicle system. The newly added RX Morizo RR high-performance model is expected to use a 2.0L turbocharged engine and dual electric motors, with a combined horsepower of 600 horsepower. The standard model will cancel the pure gasoline version and instead focus on Hybrid and PHEV. The PHEV version uses a 2.5L system with a combined horsepower of 329 horsepower and a pure electric range of 135 kilometers.

Toyota's signature car series Corolla is expected to launch a mass-produced prototype in October this year. It will be equipped with a new 1.5-liter engine specially developed for the gasoline-electric system. The average fuel consumption is expected to exceed 30 kilometers per liter, and it will provide a variety of power sources such as Hybrid, PHEV and pure electric power.

According to foreign media reports, sales of Honda CR-V in the U.S. market from January to September 2026 reached 336,834 units, surpassing Toyota RAV4 by approximately 83,000 units. Although the CR-V has not yet been significantly redesigned and a new generation of models is already under development, its balanced proportion of gasoline and gasoline-electric power (47%/53%) has become the key. The sales of RAV4 have lagged behind due to the complete elimination of pure fuel power in the new generation of models. Unless the supply is fully restored, it will have a chance to overtake.

Although the global auto market is dominated by SUVs, sales of many mainstream sedans in the U.S. market bucked the trend and surged in the first nine months of this year. Among them, the Toyota Camry grew by 11.2%, and the Honda Accord surged by 32.7%, indicating consumers' renewed interest in sedans.
