Description

电动汽车电池安全处理方法和电池安全管理装置
技术领域 本发明涉及通信领域中汽车电池技术领域， 具体地， 涉及电动汽车电 池安全处理方法及电池安全管理装置。 背景技术 我国现有的电动汽车充 /换电设施大部分服务于特定对象，并未进行商 业运营。 如电动公交线路的充电站、 奥运电动公交车充电站， 属于各企业 电动汽车示范运行的配套工程， 企业内部消化运营费用。
如果希望对社会开放电动汽车充 /换电服务， 需要解决很多问题， 而电 池资产管理问题是其中一项棘手且难于解决的问题。 目前解决电池资产管 理问题的方式， 主要是釆用粘贴电子标签或条形码来记录电池信息， 信息 存储为明文形式， 具有易获取、 易篡改、 易破坏等特点。 另外， 对于电池 的防丟失处理釆取跟踪汽车从而跟踪电池的方式。
目前电动汽车电池资产管理技术主要存在如下问题：
1.电池资产管理手段容易被破坏
电池作为一种有形资产， 需要身份标识信息以便进行管理， 目前釆用 在电池或电池箱表面粘贴标识的形式， 如粘贴条形码或者电子标签， 由于 标识本身的物理特性， 导致这种方式信息非常容易被损坏和篡改， 不能起 到资产管理的目的。
2.电池资产管理信息保存及传输问题
电池在釆购、 库房、 运行等环节， 资产信息不断的发生变化， 需要对 电池的信息进行记录和上传。 釆用粘贴条形码的形式， 只能存储电池 ID 号信息， 电池的动态信息不能记录。 另外， 只能通过手持设备进行近距离 一对一的读取， 不能实现批量的读取操作， 不适用于库房管理。 釆用粘贴 电子标签的形式，如果釆用高频电子标签，则信息读取距离只能达到 10cm 左右， 不能满足实际应用场景。 如果釆用无源超高频电子标签， 虽然读写 距离可以满足要求， 但超高频电子标签的用户数据存储空间一般最多只能 保存 512bit的数据， 信息存储量较小， 不能满足记录电池全生命周期管理 中， 对于动态数据的实时记录要求。
3.电池资产管理信息安全隐患
电池的资产归属信息、 租用信息、 性能参数信息等一些关键数据， 只 能由运营商进行修改， 不能开放给用户， 因此对于电池信息的存储及传输 需要进行加密处理。 而当前釆取的资产标识没有安全算法的支撑， 并且也 没有釆取安全管理及保密措施， 数据可以任意被获取或修改， 不能实现安 全的管理。
4. 电池的防丟措施不易推广
釆用跟踪汽车从而跟踪电池的方式防止电池的丟失， 此种方式要求汽 车用户安装 GPS定位功能设备， 并需要保证用户个人不能自行拆换电池， 具有很强的制约性。 另外， 用户必须安装 GPS定位设备将增加成本， 跟踪 汽车将侵犯汽车用户的隐私。 发明内容

电动汽车的电池作为运营商的资产，具有流动性强、信息更新速度快、 安全性要求高、 不易管理等特点， 并且电池的造价高， 涉及运营商、 电力 公司、 用户等多方利益。 因此需要建立完善的电池资产管理系统， 保证电 池的正常流通。 本发明是针对电动汽车充 /换电运营模式下， 汽车用户釆用 更换电池或整车充电时对于电动汽车电池安全处理的一种系统。
本发明通过电池安全管理装置 （ Battery Safty Managment Device , 以 下简称 BSMD ) 完成在电池建档、 运行、 换电、 充电、 库房管理等环节， 对于电池资产信息的记录、 加密和上传， 保证电池信息能完整记录、 安全 传输到后台的电池资产管理系统中， 电池资产管理系统保存电池的全部资 产信息、 过程信息等， 而电池安全管理装置中保存电池的资产信息及最近 几次的过程信息， 而需要保存几次过程信息以及哪些信息需要密文保存和 传输， 由运营商提出的需求而定。
当运营商釆购电池并进行电池信息的建档时， 由于资产信息代表电池 的唯一身份， 因此具有高保密的要求。 首先在电池资产管理系统中生成购 买电池的基本信息， 此信息为加密信息。 电池资产管理系统与电池安全管 理装置通过认证后， 通过读写设备将电池资产管理系统中的加密信息写入 电池安全管理装置的装置存储器中。
当电动汽车的用户在充换电站进行换电池情景下， 将换下的没电的电 池， 通过读写设备将电池安全管理装置中电池的相关信息读取到后台电池 资产管理系统中， 电池资产管理系统将电池的当前状态信息更新到电池安 全管理装置中， 电池资产管理系统的信息与电池安全管理装置中存储的信 息保持一致。 对于将要安装到汽车上的电池， 通过读写设备读取电池的编 池资产管理系统， 另外通过读写设备将绑定信息写入到电池安全管理装置 中。 从而完成电池换电模式下资产信息的更新、 对应和记录。
当电动汽车的用户对电池进行充电时， 电动汽车的充电桩中安装安全 芯片， 如果电池与充电桩的运营商同属一家， 则电池安全管理装置中的安 全芯片与充电桩中的安全芯片密钥匹配， 可以先进行认证， 并将充电桩的 信息存储到电池安全管理装置中， 而充电桩也能记录此次充电的电池的信 息并上传到后台的电池资产管理系统。充电桩通过 CAN(控制器局域网络， Controller Area Network )、总线与电动汽车的 BMS(电池管理系统， Battery Managment System )连接， 而电池安全管理装置也通过 CAN总线与 BMS 连接， 从而实现充电桩和电池的通信。
当电动汽车在运行过程中， 需要记录电池的电流、 温度等信息， 并将 这些信息上传到电池资产管理系统， 对这些信息进行计算， 作为电池报废 与否的依据。 电池安全管理装置通过 CAN总线与 BMS连接， 可以周期性 记录 BMS输出的电池信息， 并记录到装置存储器中。
当电池在库房中存放时， 需要对电池进行出入库管理、 充电管理及盘 点管理， 利用布置到各种位置的读写设备实现电池数据的读写， 读写设备 与电池资产管理系统通过串口总线连接。 对于出入库管理， 需要安装读头 在库房出入处， 当电池入库和出库时， 对电池进行批量的身份信息读取， 记录到库房管理系统中。对于电池的充电管理，通过 CAN总线读取到 BMS 中电池的充电信息， 通过安装在货架上的读头， 读取电池的充电信息上传 到电池资产管理系统。 对于电池的库房盘点管理， 利用安装在货架上的读 头， 定期读取电池安全管理装置中的电池信息， 从而实现电池的盘点。
当电池在更换过程中发现读写设备不能实现与电池安全管理装置的 认证时， 说明电池已经被更换， 则需要根据运营商与汽车用户签订的租赁 协议， 追究汽车用户的责任， 从而保证运营商的合法利益， 实现电池的防 丟。
为实现上述各环节的安全认证和数据加解密处理， 需要建设密钥管理 系统， 釆用相同的密钥对电池安全管理装置中的安全芯片、 电池资产管理 系统的密码机和充电桩中的安全模块进行密钥发行。 密钥发行的基本流程 图如图 1所示， 包括： 步骤 101 : 建立统一的密钥管理系统， 通过该系统对电池资产管理系 统中的相关安全设备进行统一的密钥发行， 包括 BSMD装置中的安全芯 片、 充电桩中的安全芯片和部署到电池资产管理系统中的密码机。
步骤 102-103 : 利用密钥管理系统生成的密钥， 通过发行系统对安全 芯片和密码机进行发行。
步骤 104-108: 通过将发行后的安全芯片安装在充电桩和 BSMD中， 将发行后的密码机部署到电池资产管理系统中。
步骤 109: 完成密钥发行及安全芯片的部署， 建立完整的安全认证体 系。
本发明公开的电池安全管理装置安装在电动汽车的电池箱内， 通过
CAN总线与电动汽车内的电池管理系统 （ Battery Managment System , 简 称 BMS )连接进行数据交互，通过无线方式与电池资产管理系统进行数据 交互。 电池安全管理装置功能结构框图及其与外围设备的接口示例如图 2 所示， 包括：
有源射频收发模块 210: 釆用 RFID (射频识别技术， Radio Frequency
IDentification )模块， 对外与读写设备进行无线的数据读写操作， B SMD 装置内部通过 RFID将读写数据经过微处理器 230与安全芯片 240和数据 存储单元 250进行数据交互。
CAN总线接口 220： 釆用 CAN总线接口芯片及外围电路， 对外实现 与 BMS进行数据通信， 对内将数据发送到微处理器 230中。

安全芯片 240: 釆用具有加密算法的安全芯片， 对关键数据进行加解 密处理、 身份认证等， 保证数据的安全性。
数据存储单元 250: 釆用可重复擦写形式的存储单元， 对电池的数据 进行存储。
电源模块 260: 包括锂电池供电和电源稳压两个功能模块， 锂电池为 可充电电池， 当汽车运行或者电池箱充电时， 电池箱可以为电池安全管理 装置提供 24V电源，此电源作为有源射频收发模块的电源并且为锂电池充 电。 当没有供电来源时， 需要通过锂电池本身的电能保证有源射频收发模 块的工作。
时钟模块 270: 主要是作为电池的计时时钟源， 可以将时间信息和电 池信息同时记录到电池安全管理装置中。
