    • A charge and discharge control device for controlling a battery in an electric vehicle to be charged and discharged with electricity, the electricity being transmitted and received through a power line, and being bought and sold, includes a switching unit, a communication unit, a determination unit and a controller. The switching unit switches charge and discharge. The communication unit receives current electricity price. The determination unit determines first and second electricity price thresholds. The first electricity price threshold is determined using difference between current and start times, and difference between current and target amounts of charge. The second electricity price threshold is equal to or larger than the first electricity price threshold. The controller controls the switching unit to charge the battery if the current electricity price is smaller than the first electricity price threshold, and discharge if the current electricity price is larger than the second electricity price threshold.
    • 一种用于控制电动车辆中的电池进行充电和放电的充放电控制装置,所述电力通过电力线被发送和接收并被买卖,包括切换单元,通信单元,确定 单位和控制器。 开关单元切换充电和放电。 通信单元接收当前电价。 确定单元确定第一和第二电价阈值。 使用电流和起始时间之间的差异以及电流和目标电量之间的差异确定第一电价阈值。 第二电价阈值等于或大于第一电价阈值。 如果当前电价小于第一电价门槛,则控制器控制开关单元对电池充电,并且如果当前电价大于第二电价阈值则放电。
