解题方法
1 . 随着全球对环保和可持续发展的日益重视,电动汽车逐步成为人们购车的热门选择.有关部门在高速公路上对某型号电动汽车进行测试,得到了该电动汽车每小时耗电量
单位:
与速度
单位:
的数据如下表所示:
为描述该电动汽车在高速公路上行驶时每小时耗电量
与速度
的关系,现有以下两种函数模型供选择:①
,②
.
(1)请选择你认为最符合表格中所列数据的函数模型(不需要说明理由),并求出相应的函数解析式;
(2)现有一辆同型号电动汽车从
地出发经高速公路(最低限速
,最高限速
)匀速行驶到距离为
的B地,出发前汽车电池存量为
,汽车到达
地后至少要保留
的保障电量(假设该电动汽车从静止加速到速度为
的过程中消耗的电量与行驶的路程都忽略不计).已知该高速公路上有一功率为
的充电桩(充电量
充电功率
充电时间).若不充电,该电动汽车能否到达
地?并说明理由;若需要充电,求该电动汽车从
地到达
地所用时间(即行驶时间与充电时间之和)的最小值.
