图1为按照本发明一个实施例的电池充电***的示意图。
如图1所示,按照本实施例的电池充电***10包含充电模块110、动力切换模块120、通信切换模块130和本地监控模块140。
在图1所示的电池充电***10中,充电模块110为核心部件,其例如将外部电源的交流电能转变为直流电能以实现对电池组B1-Bn的充电。如图1所示,充电模块110至少包含两个通信接口以分别与电池组B1-Bn的电池管理***(未示出)和本地监控模块140通信。
参见图1,动力切换模块120位于充电模块110与电池组B1-Bn之间。特别是,动力切换模块120包含多个通断状态可控的开关元件,每个开关元件连接在充电模块110与多个电池组B1-Bn的其中一个之间以形成相应的充电通道,由此使得充电模块110能够选择性地对多个电池组B1-Bn中的任意一个进行充电或与多个电池组B1-Bn的任意一个建立充电连接。
再次参见图1,通信切换模块130位于充电模块110与电池组B1-Bn之间以使充电模块110能够选择性地与多个电池组B1-Bn的任意一个的电池管理***进行通信。特别是,通信切换模块130包含多个通断状态可控的开关元件,每个开关元件连接在充电模块110与多个电池组B1-Bn的其中一个的电池管理***之间以形成相应的通信通道。在充电过程中,借助于所建立的与电池管理***的通信连接,充电模块110可以获取电池组的状态信息并基于状态信息优化充电操作。
优选地,上述开关元件例如可以是直流接触器,并且更好地,可以是常开直流接触器。
优选地,充电模块110与电池组B1-Bn的电池管理***的通信采用CAN总线协议。
本地监控模块140配置为与动力切换模块120和通信切换模块130相连以控制充电通道和通信通道的通断状态。例如本地监控模块140可通过控制直流接触器实现充电通道和通信通道的导通和关断。另一方面,本地监控模块140还可与电池组B1-Bn的电池管理***通信以接收充电请求和电池组的状态信息。在本实施例中,如图1所示,本地监控模块140经通信切换模块130与电池组B1-Bn的电池管理***通信。优选地,本地监控模块140与电池管理***的通信采用CAN总线协议。
此外,如图1所示,本地监控模块140还可与充电模块110和远程监控模块160通信。优选地,本地监控模块140与充电模块110的通信采用CAN总线协议,而与远程监控模块160的通信采用以太网通信协议。
优选地,图1所示的电池充电***10还包含通信开出板150。本地监控模块140可经该通信开出板150与动力切换模块120和通信切换模块130相连,从而对充电通道和通信通道的通断状态进行控制。
优选地,在对充电通道和通信通道的通断状态的控制中,本地监控模块140应确保充电模块110在工作时仅与多个电池组B1-Bn的其中一个建立相应的充电连接和通信连接。更好地,本地监控模块140例如可借助互锁机制来确保单一的充电连接。
在本实施例中,优选地,充电模块110可在不同的电池组B1-Bn之间实现充电操作的自动切换。
图2为可应用于图1所示实施例的充电自动切换方法的流程图。
图2所示的流程图开始于步骤201,在该步骤中,开启本地监控模块140和充电模块110。可选地,在本步骤中,还可以开启远程监控模块160以提供远程控制功能。随后进入步骤202,查询本地监控模块140、远程监控模块160和充电模块110的状态以确定是否能够正常运行,如果能,则进入步骤203,否则进入步骤204,生成***异常的报警消息。
在步骤203,本地监控模块140以轮询方式从电池组B1-Bn的电池管理***接收消息。例如,如图1所示,本地监控模块140经通信开出板150和通信切换模块130与电池组B1-Bn的电池管理***通信以接收可能的充电请求。
在步骤205,本地监控模块140判断是否接收到来自电池组B1-Bn的电池管理***的充电请求,如果存在充电请求,则进入步骤206,否则返回步骤203。
在步骤206,本地监控模块140经通信开出板150与发送充电请求的电池组的电池管理***建立通信连接并且屏蔽与其它电池组的电池管理***的通信。需要指出的是,在本步骤中,当存在多个充电请求时,本地监控模块140可以根据设定的策略确定电池组的充电顺序,并且与优选度最高的电池组的电池管理***建立通信连接。
随后进入步骤207,本地监控模块140例如经通信开出板150与动力切换模块120通信,指示动力切换模块120开启与步骤206中已经建立通信连接的电池组相对应的充电通道并且将其余的充电通道锁死,与此同时,本地监控模块140还例如经通信开出板150与通信切换模块130通信,指示通信切换模块130仅仅开启与步骤206中已经建立通信连接的电池组相对应的通信通道。
接着进入步骤208,本地监控模块140查询处于充电状态下的电池组的状态信息。这里所述的状态信息例如包括但不限于电池的SOC、温度等。
随后,在步骤209,本地监控模块140根据电池组的状态信息判断对电池组的充电是否完成,如果完成,则进入步骤210,否则返回步骤208。
在步骤210,本地监控模块140例如经通信开出板150与动力切换模块120和通信切换模块130通信,指示动力切换模块120和通信切换模块130将步骤207中导通的充电通道和通信通道切换至断开状态,并且取消对其它电池组的电池管理***的屏蔽。在完成步骤210之后,图2所示的方法返回步骤203,以自动对下一个电池组进行充电。
需要指出的是,在图2所示的方法流程中,可选地,本地监控模块140执行的全部或部分操作也可以由远程监控模块160来执行。
虽然在图1所示的实施例中,本地监控模块140仅对一个包含充电模块、动力切换模块和通信切换模块的电池充电单元的运行进行管理,但是本发明也可以拓展到本地监控模块140对两个或更多个电池充电单元的运行进行控制和管理的情形。
图3A为按照本发明另一个实施例的电池充电***的示意框图。在图3A所示的电池充电***10中,本地监控模块140,可以同时管理多个电池充电单元的充电操作。
图3B为可应用于图3A所示实施例的电池充电***的电池充电单元的示意框图。如图3B所示,电池充电单元C1-Cn的每一个都包括充电模块110、动力切换模块120和通信切换模块30,这些模块具有与图1和2所示实施例相同的特征、功能和工作原理。特别是,本地监控模块140可按照与图1和2所示实施例相同的方式控制每个电池充电单元中充电模块、动力切换模块和通信切换模块。
图4为按照本发明另一实施例的电动汽车充电站的示意框图。
如图4所示,本实施例的电动汽车充电站1包含一个或多个按照上面借助图1-3所述实施例的电池充电***10A-10N和远程监控模块20,其中,远程监控模块20被配置为与电池充电***10A-10N中的本地监控模块通信。
提供本文中提出的实施例和示例,以便最好地说明按照本技术及其特定应用的实施例,并且由此使本领域的技术人员能够实施和使用本发明。但是,本领域的技术人员将会知道,仅为了便于说明和举例而提供以上描述和示例。所提出的描述不是意在涵盖本发明的各个方面或者将本发明局限于所公开的精确形式。
