Description

用于给电动汽车充电的设备
技术领域
本发明涉及一种用于给电动汽车充电的设备。
背景技术
在电子技术中,用于在无需取出能量储存器(如电动汽车的牵引电池)的情况下通过简单地置入或插入来向可移动的电池驱动的装置、机器或机动车辆供应能量的任何固定设备或者电子装置都称为充电站。用于电动汽车的充电站有时也被称为“加电站”并且可以包含多个充电点。
在此,尤其已知直流快速充电系统,如在欧洲推广的所谓组合充电系统(combinedcharging system,CCS)。在通用的直流充电下,来自充电桩的直流电直接被输入至车辆中,并在此通过电网的高效整流器或通过太阳能加电站的缓冲蓄能器提供直流电。在车辆中存在电池管理系统,该电池管理系统与充电桩通信,以便调整电流强度或在达到容量极限时终止该过程。
在此,功率电子器件通常位于充电桩中。由于充电桩的直流接线端直接与牵引电池的对应接线端相连接,所以能够以低损耗传输高充电电流,这可以实现短的充电时间,但也产生显著的废热。
还已知用于冷却电动车辆的充电系统的不同概念。DE102011082565A1例如公开了一种用于电池驱动的机动车辆的电力充电系统,该电力充电系统省去了将电池模块集成到车辆侧的冷却剂环路/制冷剂环路中,从而在需要时在充电过程期间仅经由机械接口在电池单元与外部冷却系统之间进行热交换。安置在外部冷却系统处的接触面(该接触面作为单独部件形成换热器的第二半部)应有助于将该外部系统更好地用作充电基础设施的一部分,其中可以服务于多个车辆。
US2014322570A涉及一种具有用外部电力充电的电池的电池装置、一种具有用于给电池充电的充电装置的与充电相关的装置、以及一种冷却剂装置,该冷却剂装置用于将用于冷却电池和充电装置的冷却剂引入电池装置和与充电相关的装置中。第一冷却剂装置应可以实现在第一状态与第二状态之间进行切换:在第一状态中,冷却剂被引入电池装置中;在第二状态中,冷却剂被引入与充电相关的装置中。
FR2978702A、US2009256523A以及US2011111269A讨论了其他的系统冷却设计。

图3和图4再现了来自使用者视角的、处于关闭状态下的此类模块化构造的冷却装置(16),而根据图5的半透明的图示提供了向该冷却装置的壳体中的视图。该壳体容纳至少一个模块(19)并且使得能够看到其带有总开关(24)的开关盒(23)和把手(25)以及电接线盒(26),该电接线盒和开关盒(23)一样是可以很好地触及的并且由此便于维护地安排在这两侧的把手(25)之间。
图6至图11从不同视角展示了模块(19)自身的构造特征。如尤其图11所展示地,该模块的风机(20)在模块(19)内被安排成使得进气口(31)和出气口(32)相互成直角。图7至图9使得还能够看到用于膨胀箱和冷凝水的在底部附近的溢流口(30)。
图12展示了充电桩(11)的构造,该充电桩自身包括次级冷却环路(33)、另外的泵(34)、换热器(35)、低电压源(36)以及补偿容器(46)。在此,用油、氟氯烃(FCKW)或其他非水相的冷却剂填充的次级冷却环路(33)在流体意义上将由低电压源(36)馈送的泵(34)与补偿容器(46)和换热器(35)相联接,该换热器进而在热学意义上将初级冷却环路(47)与次级冷却环路(33)相联接。根据附图,充电桩(11)还具有充电控制单元(37)、用于测量直流电消耗的能量计数器(38)、电流传感器(39)、电压传感器(48)、两个高电压端子(40,43)、缆线夹套(44)以及直流电压缆线(45),这些直流电压缆线经由充电控制单元(37)、能量计数器(38)、电流传感器(39)和电压传感器(48)将第一高电压端子(40)与第二高电压端子(43)相连接并且自身通过缆线夹套(44)相互固定。在此,上部接线区域容纳第二高电压端子(43),而位于充电桩(11)的钢基座(41)正上方的该充电桩的下部接线区域具有第一高电压端子(40)。
图13将观察者的注意力引向了充电桩(11)的外观,该充电桩的由铝挤压型材制造的壳体(55)被呈铝复合板的构型的缆线引导框架(50)所包围。为此,仅充电桩的CCS充电插头(54)、与之相邻的紧急断路器(53)以及25.4cm的显示装置(51)是可从外部触及的,该显示装置是由黑色玻璃板承载的。
