Description

用于充换电站的电池温度控制装置和电动车充换电站 技术领域
本发明涉及新能源汽车技术领域，尤其涉及一种用于充换电站的电池温度控制装置和电动车充换电站。
背景技术
随着电动车的快速发展，如何快速的实现电动车的能量补给，使电动车像传统燃油汽车一样便捷，是电动车行业面临的重要难题之一，充换电站的出现成功解决了这一难题。充换电站将车上需要补能的电池更换为电池仓内满电的电池，并将替换下的电池送入电池仓进行充电。锂离子电池是电动车的核心部件，随着用户对电动车的要求提高，对电池系统的功率性能和快充性能的要求也越来越高，伴随而来的就是对电池冷却系统设计要求的提高。锂离子电池充电时的温度保持在20-35℃范围内为最佳。当锂离子电池低于此温度范围时，容易出现充电析锂或充放电降功率的现象；当锂离子电池温度超过此范围时，锂离子电池的循环寿命会急剧下降，而且还可能会出现热安全问题。
在大倍率充放电工况下，传统的自然冷却和强制风冷往往不能满足散热要求，因此散热效率更高的液冷方式越来越多的成为了锂电池的主流散热方式。目前充换电站的水冷系统至少存在如下缺点：
(1)现有的水冷系统的显示屏放置于水冷系统的机组上，控制屏前方不可放置阻挡显示屏的设备，限制了充换电站整站的设计和布局的灵活性。
(2)断路器、继电器等元器件通常安装在水冷机组内部，当水冷机组发生故障需要及时断电，或手动回复时，会对充换电站其他设备的正常运行造成影响。
(3)现有的水冷系统通常在液体不能完全浸没水冷系统水箱内的电加热时发出低液位告警，水冷系统停止工作，然后通过安装在液冷机组上的注液口进行加液，并实时观察冷却液加注到的液位，并需手动恢复水冷系统至正常运行。但至少会存在如下问题：
A：注液口、液位计放置在液冷机组上，为方便工作人员的操作和实时观察液位，会限制充换电站的布局和结构设计；
B：水冷系统加注到一定液位后，再手动恢复水冷系统的运行，增加了操作负担，导致水冷系统恢复不及时。
综上所述，现有的充换电站水冷系统的控制部和管路部上的部分元器件置于水冷机组中或水冷机组附近，无法根据具体布局需求调整各元器件 所在位置，使充换电的布局具有局限性。因此，为实现充换电站的普及，推动新能源汽车的发展，如何设计和制造一种满足上述充换电站内部设计和布局的多样性的用于充换电站的水冷系统成为亟待解决的技术问题。

具体实施方式
为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功效,以下结合附图及较佳实施例，对依据本发明提出的一种用于充换电站的电池温度控制装置和电动车充换电站的具体实施方式及其功效，进行详细说明。
如图1所示，本发明提供了实施例提供了一种用于充换电站的电池温度控制装置，包括:管路部1、液冷机组2和控制部3，其中，管路部1连接所述充换电站的一个或多个电池，用于为所述电池提供冷媒，以加热或冷却所述电池；液冷机组2和管路部1相连接，作为示例，液冷机组2可通过软管和管路部1相连接，用于制冷或加热所述管路部1的冷媒，所述冷媒可以为水，这样可降低所述温度控制装置成本、提高冷却及加热的效率，对应的，液冷机组2为水冷机组。控制部3和液冷机组2相连接，作为示例控制部3可通过线缆和液冷机组2相连接，用于控制所述管路部1和液冷机组2。控制部3与液冷机组2采用分体式设计，通过线缆连接；管路部2和液冷机组2采用分体式设计，通过软管连接，从而可将控制部3以及管路部2放置在既不影响充换电站内部结构设计和布局，又能方便工作人员操作和监测的位置，从而可以满足充换电站内部结构设计和布局的多样性的需求。
需要说明的是，本发明所述充换电站为电动车充换电站，所述电动车并不限于纯电动车，还包括可通过所述充换电站进行充换电的混动车等。
作为示例，管路部1包括通水管路11和加液管路12，通水管路11和加液管路12分别与液冷机组2连接。每条通水管路11包括一条供水管路111和与所述供水管路111对应的回水管路112，所述供水管路111用于进水，所述回水管路112用于回水。加液管路12用于为液冷机组2加水，由于管路部1与液冷机组2为分体式设计，加液管路12的加液口与液冷机组2也为分体式设计，加液管路12可根据具体的布局需求，放置在既不影响充换电站结构设计和布局，又方便进行加液操作的位置。
为了及时发现通水管路11的漏液故障，避免因管路漏液造成重大故障和影响，可在每条所述供水管路111和所述回水管路112上，安装一个或多个漏液传感器113，作为示例，所述漏液传感器113安装在所述供水管路111和所述回水管路112的易漏液处，所述易漏液处包括管路连接处等，本发明实施例漏液传感器113安装设计，提高了温度控制装置漏液检测的准确度和可靠性，从而提高了充换电站运营的安全性和可靠性，避免漏液引 起的安全事故的发生。
所述电池温度控制装置正常工作时，供水管路111流经需冷却或加热的电池后，再流入回水管路112，供水管路111与回水管路112是相通的，但若所述电池温度控制装置在正常工作时转为没有接入电池的状态，供水管路111与回水管路112则无法接通，造成通水管路11堵塞，有可能造成安全事故。为了避免此类安全事故发生，可在管路部1中设置保护管路13，与通水管路11相连接，用于在通水管路11堵塞时，接通通水管路11。
作为一种示例，如图1所示，保护管路13包括接通部131、第一保护管路132和第二保护管路133，其中，第一保护管路132一端与接通部131连接，另一端与供水管路111连接；第二保护管路133一端与接通部131连接，另一端与回水管路112连接。
液冷机组2内部设有多种水冷结构和元器件，具体包括压缩机、水泵、风机、电加热、水箱、电池阀、温度传感器、膨胀阀、冷凝器、电气部件等中的一种或多种，当电池温度过高时，开启制冷模式，通过压缩机、水泵、膨胀阀等对电池进行冷却。当电池温度过高时，开启加热模式，通过电加热和水泵对电池进行加热。通过加热和制冷两种模式将电池的温度控制在合理的范围内，从而保证电池的充电速度和电池的寿命。液冷机组2的组成可为现有的任意一种水冷结构，因此，液冷机组2内部的具体组成以及各部件间的连接关系不在此赘述。本发明实施例重点对液冷机组2中的防水设计进行了处理。作为示例，如图2和图3所示，在液冷机组2内的怕水元器件下设有对应的抬高结构21，将怕水元器件进行适当的抬高，需要说明的是，每个怕水元器件被抬高的高度和其他怕水元器件被抬高的高度可以一致，也可以不一致，具体抬高的高度可根据充换电站的布局、液冷机组2的高度、以及被抬高的怕水元器件的高度等参数进行设定。其中，怕水元器件包括电气部件、水泵、压缩机和风机中的一种或多种，所述电气部件包括电线、插孔、继电器、微断器和主控板中的一种或多种。作为示例，抬高结构21为凸台，所述凸台通过螺栓与被抬高的元器件相连接。但可以理解的是，抬高结构21并仅限于凸台，也可为其他结构，例如可以为丝杠结构，还可通过丝杠结构来调整被抬高的高度。
进一步的，有些怕水元器件并非所有的组成部分均怕水，例如水泵，水泵中的怕水组成部分主要为电机，因此可以只将水泵中的电机下部设置抬高结构21，水泵中除电机以外的其他部分可不做抬高处理，可以减少所述电池温度控制装置的成本，节约空间，增加布局多样性。本发明实施例所述液冷机组2中的防水设计，避免了浪费空间，增加充换电站整体的系统设计和布局的灵活性，降低了所述温度控制装置的成本、增加了防水器件选型种类。
为了防止液冷机组的进风口和出口距离近，导致吹出的热风又直接被风机引入液冷机组，使冷空气温度过高，无法进行换热，水冷系统发生故障等情况。如图4所示，可在液冷机组2的第一侧面上设有第一进风口22，与第一侧面相邻的第二侧面和第三侧面的至少一面上设有第一出风口23，在液冷机组2内部，第一进风口22和第一出风口23通过风道相连接。例如，在与第一侧面相邻的第二侧面和第三侧面上分别设有第一出风口23，在用于充换电站时，根据布局需求，选择其中一个第一出风口23，将另外一个第一出风口23，通过盖板封闭起来，这样的结构可增加所述电池控制装置在充换电站中的布局的多样性和灵活性。
图5和图6中，以一个第一出风口23对进出风口进行说明，第一进风口22处安装有散热风机24，根据要求使散热风机24在抽风模式和吹风模式之间切换。作为一种示例，可通过更改所述散热风机24的内部接线，使所述散热风机24工作在抽风模式和吹风模式，从而以实现第一进风口22和第一出风口23的进出风功能互换。具体地，如图5所示，散热风机24工作在吹风模式，此时，第一出风口23用于为出风口，用于排出热空气，对应的，第一进风口22为进风口，用于吸入冷空气。改变散热风机24的接线，使散热风机24工作在抽风模式，如图6所示，此时，第一出风口23转换为进风口，用于吸入冷空气，对应的，第一进风口22转换为出风口，用于排出热空气。作为上述示例的变形，也可在第一出风口23设置抽风风机和吹风风机，然后控制散热风机24连接抽风风机，使其工作在抽风模式，或者控制散热风机24连接吹风风机，使其工作在吹风模式。
为了使液冷机组散热的空气只流经液冷机组2，完全与充换电站换电站隔离，可在充换电站开设第二进风口和第二出风口，所述第二进风口和第一进风口22通过风道相连接，所述第二出风口和第一出风口23通过风道相连接。这样既可以满足液冷机组2的对散热的要求及充换电站的密封性，又不会将热风排放到充换电站内部，影响充换电站内部的流场和温度场。需要说明的是，第二进风口和第二出风口的进出风功能，会跟随第一进风口22和第一出风口23的进出风功能互换而互换，从而满足充换电站内部结构设计和布局的多样性。通过设计风道，使充换电站内电池的发热量、温度控制装置排放的热量均通过风道直接排至充换电站外，防止充换电站内的温度因受到上述排热量的影响而增高，避免因上述排热量引起的充换电站内没有满足温度要求的冷空气与冷媒进行热交换，防止温度控制装置出现高压告警。现有的充换电站内由于没有设置本发明实施例所述风道结构将热量排出从充换电站外，因此通常采用空调等维持充换电站内的温度，本发明实施例将热量直接排出充换电站外，降低了充换电站的成本，避免了能量浪费。此外，所述温度控制装置排出的热空气的温度通常高于冷空 气的温度15-20℃左右，若热风吹到在充换电站内在高温下无法正常工作的元器件，会影响该元器件的正常使用，从而影响充换电站的运营，本发明实施例的风道结构也有效避免了此状况的发生，提高了充换电运营的可靠性。
液冷机组2中设有水箱，通常也设有对应的液位计，作为示例，如图7所示，在水箱的最高液位处设有高液位传感器25，用于在通过加液管路12加液时，探测所述水箱内液体高度，并当加液至所述的最高液位处，高液位传感器25受冷却液浮力影响，发出加液完成的告警，该告警提示可设定为1mi n后自动停止，并将加液完成信号传送至控制部3，自动恢复所述温度控制装置的正常运行，水箱内还设有低液位传感器26和电加热结构27等，防止出现干烧现象。
作为示例，控制部3包括控制屏31和设置在所述控制屏31上的电控部32。控制屏31用于自动控制所述管路部1和液冷机组2的开启和关闭、设定和监测水冷参数以及进行告警等。其中，水冷参数包括供水管路111的供水温度、回水管路112的回水温度、电池温度中的一种或多种；告警包括电加热设备告警、管路部告警、水泵告警、风机告警中的一种或多种。控制部3收到高信息后可自动断开对应设备，以及发出告警提示等。由于控制屏31和液冷机组2为分体式设计，因此可将控制屏31放置在既不影响充换电站整体设计，又方便工作人员能够及时切断相关元器件供断电操作的位置，可方便工作人员的实时操作和监控，此外充换电站采用此种设布局后，可以在液冷机组2附近摆放其他设备，例如液冷机组2前端放置了空压机，操作人员也可以站在电池架外端进行操作，而不用到电池架底部进行操作。
此外，也可手动断开发出告警的设备或其他情况下需要断开的设备，手动操作可通过电控部32来实现，电控部32包括断路器，用于手动控制管路部1和液冷机组2的开启和关闭。
本发明实施例还提供一种电动车充换电站，包括一个或多个所述电池温度控制装置100，电池温度控制装置100设于所述电动车充换电站内的电池仓101内，电池仓101用于存储电池，为亏电电池充电，以及为充换电站的换电小车提供满电电池等，可以理解的是，电池仓的结构不限，可以为框架结构等，如图8所示示例，可将液冷机组2设于电池仓101底部，通过管路部1与电池仓101内的电池相连接，控制部3可设在电池仓101外部，以方便对电池温度控制装置100进行检测和操作。
