带有无线通信功能的电池模组及电池包 技术领域
本发明涉及电动车用电池包技术领域，尤其涉及一种带有无线通信功能的电池模组及电池包。
背景技术
最近几年，纯电动汽车得到了长足的发展，在全国和全世界范围内，各个国家和企业都在大力发展推行纯电动汽车。而电池包作为纯电动汽车上的能源输出机构，其重要作用也是不言而喻的。
动力电池在不到1m 3的空间中需要布置下近100组电池(锂电池电压为3～4V，电池包需输出400V电压，需要串联100组以上)，每组电池都需要采集电压、采集温度，整个包内还需要采集电流等，同时有高低压控制设备，切断设备及管理设备等，这些复杂设备间都需要线束进行连接，整个电池包内的所有线束加在一起近百米，对应的端子插头等也需要近百。
在电池包的设计过程中，需要排布低压通信线束的走向，线束的固定点位，线束的固定机构，采集点的连接方式等，是一个***而复杂的工程。同时对应着线束的排布，为了服务线束所产生的相应的零部件也占据了电池内较大的空间及较高的质量。
如果能够将电池包内的低压通信线束取消，变为无线通信，那么会节省大量的设计时间及开发成本，同时会提升电池包的体积/重量能量密度，使得电芯的布置变得更加方便。
因此，为了解决上述问题，急需发明一种新的带有无线通信功能的电池模组及电池包。

实施例一
参见图1所示，一种带有无线通信功能的电池模组，包括电池模组单元、电连接于所述电池模组单元上的用于实时检测所述电池模组单元工作参数的工作参数检测模块、用于无线接收所述电池模组单元工作参数的无线通信接收芯片和用于无线发送所述电池模组单元工作参数的无线通信发送芯片；所述工作参数检测模块通过信号线与所述无线通信发送芯片电连接；所述无线通信发送芯片与所述无线通信接收芯片通过信号线电连接。所述的带有无线通信功能的电池模组还包括与所述电池模组单元通过供电线并联的供电稳压模块，所述供电稳压模块分别通过供电线与所述工作参数检测模块、所述无线通信发送芯片和所述无线通信接收芯片电连接。所述工作参数检测模块包括并联于所述电池模组单元输出端上用于检测电池模组单元输出电压的电压传感器和用于检测所述电池模组单元温度的温度传感器，所述电压传感器和所述温度传感器分别通过信号线与所述无线通信发送芯片电连接；所述电压传感器和所述温度传感器分别通过供电线与所述供电稳压模块电连接。所述电压传感器、所述温度传感器、所述无线通信发送芯片和所述无线通信接收芯片呈一体化设置于同一PCB板上。所述无线通信接收芯片为NFC无线通信接收芯片。所述无线通信发送芯片为NFC无线通信发送芯片。
本实施例中所述带有无线通信功能的电池模组，包括电池模组单元、电连接于所述电池模组单元上的用于实时检测所述电池模组单元工作参数的工作参数检测模块、用于无线接收所述电池模组单元工作参数的无线通信接收芯片和用于无线发送所述电池模组单元工作参数的无线通信发送芯片；所述工作参数检测模块通过信号线与所述无线通信发送芯片电连接；所述无线通信发送芯片与所述无线通信接收芯片通过信号线电连接；通过在电池模组单元之间设置所述无线通信发送芯片和所述无线通信接收芯片，将电池包内部低压采集线束取消，改为无线通信，节省包内空间，减轻电池包总重量；同时摆脱线束束 缚，采集及通信模块能够布置在更加合适的位置。
本实施例中所述带有无线通信功能的电池模组，所述无线通信发送芯片采用NFC无线通信发送芯片，所述无线通信接收芯片采用NFC无线通信接收芯片；选择近场通信作为无线传输的媒介(NFC)，NFC是由非接触式射频识别(RFID)及互连互通技术整合演变而来，通过在单一芯片上集成感应式读卡器、感应式卡片和点对点通信的功能；选择NFC的原因为，第一，技术成熟度非常高，伴随着在在移动场景的使用，目前NFC的成本非常低、可靠程度非常高。第二，在13.56MHz频率运行于20厘米距离内。其传输速度最高可达424Kbit/秒，满足目前电池包内CAN协议需要250Kbit波特率的需求。第三，功耗非常低，在全工况的情况下单一NFC芯片耗电也只有20μA，不会增加电池包额外电耗。
本实施例中所述带有无线通信功能的电池模组，电池包原有的低压通信工作模式，是将所有接触点位与包内的BMS相连接，BMS固定在包内的指定位置，所有的线束在此处汇集。一方面传递数字信号，同时也传输模拟信号(电压、电流即传输模拟信号至BMS主控板进行处理)，数字信号的传输直接变为无线传输即可，但模拟信号的传输需要一定的处理。
本实施例中所述带有无线通信功能的电池模组，每串电池模组配一块PCB板，上面配有LTC6811(电压传感器)进行采集电压，同时从一串电池两端取电经稳压源后给整块PCB供电，同时采集温度模拟信号，经模-电电路转化为电信号，整块板上的电压/温度信息经由NFC芯片发送给临近的下级PCB板。在电流采集处同时配PCB板，板电压从临近模组取电，通过霍尔传感器采得电流模拟信号，经过MLX91208，转化为数字信号，经由NFC模块向下传递。在控制端，同样道理，就近从模组取电，经由NFC接收控制信号。整个***采用菊花链形式(收尾相连)，既无需每个模块都与BMS通信，每个模块都只与其最近的连接，只需有一环与BMS连接即可。
