Description

一种可并联扩容电动摩托车动力电池系统
技术领域
本实用新型涉及一种可并联扩容电动摩托车动力电池系统。
背景技术
随着全球能源危机与环境恶化的加剧,发展新能源车辆,用电代油,成为全球实现能源安全和环境保护的必然要求,动力电池的应用有着巨大的市场前景,动力电池应用技术作为动力电池核心技术之一亦将得到广泛应用。然而电池的续航里程起着重要的决定。目前,能实现任意电池增容的方法不多,当需要电池增容时,一般是直接取下小容量电池再更换大容量电池,或是给电池进行充电…等等。但这些都无法解决根本问题并满足最终需求,同时,传统电池模块多个使用时,都需一个额外的主控制板进行容量计算和安全监控,并且不同电压准位的电池模快并联使用还需克服因容量差异产生的环流问题。
传统的动力电池模块使用数量固定,续航里程固定,不可增容。其主要无法任意扩容的主要原因:传统的动力电池模块使用时都需另由一个主控制模块来控制,模式单一,系统组成固定。电动摩托车的动力控制系统只能识别单一个容量的动力电池来源,如果使用者自行额外再并联一个电池模块进行增容使用,则电动摩托车的动力控制系统无法进行所扩容电池模块的识别,造成容量估算的错误及安全监控的疏漏。
发明内容
本实用新型弥补了传统电池系统的不足,提供一种可并联扩容电动摩托车动力电池系统。
本实用新型的技术方案是:
一种可并联扩容电动摩托车动力电池系统,至少包括一块主电池模块和一块从电池模块,所述的主电池模块和从电池模块中包括电池和电池控制管理模块,主电池模块和从电池模块通过CAN总线连接,所述的电池模块的机箱上通过机箱导向装置可并联扩容多个从电池模块,从电池模块采集电池信息,通过CAN通讯给主电池模块,再由主电池模块通讯给上一级设备,所述的电池控制管理模块中包括控制管理芯片、电压温度侦测、均衡控制芯片,报警保护芯片和电池组状态信息通信芯片。
本实用新型在每个电池模块都有一个可自动相容并识别的控制电路,多个电池模块并联使用时,不需额外的主控制模块,既可单个使用,也可多个使用,可扩充至多倍容量,增加续航力。
并且在多个电池模块并联使用时,不会因为并联使用中的个别电池模块电压差异而产生环流充电现象发生。这种并联电池之间的环流充电容易造成较低电压的电池模块在瞬间涌入大量流造成损伤及安全隐患。
附图说明
图1为本实用新型的原理图;
图2为本实用新型的结构框图。
具体实施方式
以下结合附图和实例对本实用新型作进一步的描述。
如图1、图2所示,一种可并联扩容电动摩托车动力电池系统,至少包括一块主电池模块和一块从电池模块,所述的主电池模块和从电池模块中包括电池和电池控制管理模块,主电池模块和从电池模块通过CAN总线连接,所述的电池模块的机箱上通过机箱导向装置可并联扩容多个从电池模块,从电池模块采集电池信息,通过CAN通讯给主电池模块,再由主电池模块通讯给上一级设备,所述的电池控制管理模块中包括控制管理芯片、电压温度侦测、均衡控制芯片,报警保护芯片和电池组状态信息通信芯片。
本实用新型每个模块采用相同的结构,每个电池模块都有一个电池控制模块,利用软件仲裁进行电池模块的主从分配,从电池模块采集电池信息,通过CAN通讯给主电池模块,再由主电池模块通讯给上一级设备。
本电池模块采用250kbps的CAN通讯。CAN通讯支持两种报文格式,由于标识符的长度不同,分别有标准格式11位和扩展格式29位。CAN通讯网络上的任一节点均可主动发送报文,总线空闲时,所有节点都可以发送报文;当总线发生冲突时,可通过总线的位仲裁解决,高优先级报文继续发送,而低优先级的报文退出传输。如,当几个节点同时发送报文时,节点1的报文标识符为011111;节点2的报文标识符为0100110;节点3的报文标识符0100111。所有标识符都有相同的两位01,直到第3位进行比较时,节点1的报文被丢掉,因为它的第3位为高,而其它两个节点的报文第3位为低。节点2和节点3报文的4、5、6位相同,直到第7位时,节点3的报文才被丢失(即节点2的报文高优先级,继续发送。而本发明采用29位的扩展格式,利用CAN通讯位仲裁的功能,每个电池模块并联使用时,各电池模块发送29位ID,再进行优先识别(即CAN位仲裁),最后确立主从(ID优先发送的电池模块为主模块,其余为从模块)。
在并联电池模块进行扩容使用时,因为电池模块放电端和充电端各加上了功率型二极管,所以,电池模块的放电端只能放电,充电端只能充电,以达到禁止环流充电损伤电池的目的。
