对附图的简要说明
附图说明
[0026] 图 1为本发明实施例一至四的充电站配电量配置方法的流程图；
[0027] 图 2为本发明实施例五至八的充电站配电量配置方法的流程图。
具体实施方式
[0028] 本发明最关键的构思在于： 根据距离充电站一定范围内的电动汽车的数量、 车 速、 电量等信息对充电站需要的配电量进行计算， 配电站根据需要的配电量动 态配送配电量， 大大减少车辆的充电排队吋间。
[0029] 请参照图 1， 本发明提供了一种充电站配电量配置方法， 所述方法为：
[0030] 预设以充电站为中心的监测范围；
[0031] 充电站监控平台获取所述监测范围内的电动汽车的数量、 车速、 电量；
[0032] 充电站监控平台根据所述电动汽车的数量、 车速、 电量， 计算到充电站进行充 电的车辆数量， 并发送至配电站；
[0033] 配电站根据所述的到充电站进行充电的车辆数量， 计算该充电站需要的配电量
[0034] 配电站中预存储充电站的原始配电量；
[0035] 配电站计算充电站需要的配电量与原始配电量的差值； [0036] 若所述差值大于 0， 则配电站向所述充电站输送与所述需要的配电量匹配的电
[0037] 进一步的， 充电站监控平台根据所述电动汽车的数量、 车速、 电量， 计算到充 电站进行充电的车辆数量， 具体为：
[0038] 充电站监控平台中预设拥堵车速阈值、 汽车电量阈值；
[0039] 判断是否有电动汽车的车速低于拥堵车速阈值；
[0040] 若有电动汽车的车速低于拥堵车速阈值， 则一一判断各电动汽车的电量是否低 于汽车电量阈值；
[0041] 记录电量低于汽车电量阈值的电动汽车的个数， 即为到充电站进行充电的车辆 数量。
[0042] 由上述描述可知， 在电动汽车的车速低于拥堵车速阈值吋， 根据电动汽车的数 量及电量判断需要到充电站进行充电的车辆数量， 配电站给充电站的原始配电 量够满足充电站正常车流量的充电需求， 当以充电站为中心的监测范围内出现 拥堵情况吋， 车流量对充电站的配电量需求会迅速增加， 此吋启动对需要到充 电站进行充电的车辆数量的需求， 以应对拥堵吋段的充电需求， 具有较强的对 拥堵状况下的需求处理能力。
[0043] 进一步的， 配电站根据所述的到充电站进行充电的车辆数量， 计算该充电站需 要的配电量， 具体为：
[0044] 充电站需要的配电量 =电动车的充电电压 X电动车充电电流 X到充电站进行充电 的车辆数量。
[0045] 由上述描述可知， 电动车的充电电压和充电电流一般均相同， 计算出到充电站 进行充电的车辆数量， 即可得到充电站需要的配电量， 即配电功率， 计算合理 便捷。
[0046] 进一步的， 还包括：
[0047] 若所述差值小于等于 0， 则配电站按原始配电量向所述充电站输送电量。
[0048] 由上述描述可知， 如果差值小于等于 0， 表明车流量未处于拥堵状况， 则无需 变更配电站向充电站输送的电量， 减少配电站的配电次数， 操作便捷。
[0049] 进一步的， 还包括： [0050] 若所述差值大于 0， 则配电站向所述充电站输送与所述需要的配电量匹配的电 量的同吋， 配电站、 充电站均幵启降温模式。
[0051] 由上述描述可知， 如果差值大于 0， 表明车流量较大， 需要的配电量较大， 配 电站与充电站处于负荷较大的情况， 配电站与充电站均幵启降温模式， 有利于 提高配电站与充电站的寿命。
