Description
技术领域
本发明涉及汽车电池领域,特别涉及一种被动均衡的汽车电池管理装置。
背景技术
被动均衡先于主动均衡出现,因为电路简单,成本低廉至今仍被广泛使用。其原理是依照电池的电量和电压呈正相关,根据单串电池电压数据,将高电压的电池能量通过电阻放电以与低电压电池的电量保持相等状态,也有以最高电压为判据,比如三元锂电最高4.2V,凡是超过4.2V就开始放电均衡。
因为BMS概念和产品最早是由国外提出,国外半导体厂商最先设计出专用IC,开始只是检测电压和温度,后来均衡的概念提出后,就采用了电阻放电的方法并将这个功能加入到IC中(因为这个放电控制的功能容易集成进芯片里),现在广泛应用的TI\MAXIM\LINER均有此类芯片在产,有的是将开关驱动做到芯片里,有的甚至试图将开关也做进了芯片里。从被动均衡原理及示意图中我们可以看出,如果电池组比作木桶,串接的电池就是组成木桶的板,电量低的电池是短板,电量高的就是长板,被动均衡做的工作就是“截长不补短”。电量高的电池中的能量变成热耗散掉,电能使用效率低。不仅如此,因为将电能转变成热量耗散,带来了两难的问题,这就是如果均衡电流大,热量就多,最后如何散热成为问题。
发明内容
本发明的一个目的是解决至少上述问题或缺陷,并提供至少后面将说明的优点。
本发明还有一个目的是提供一种被动均衡的汽车电池管理装置,通过电池控制器监控电池矩阵中各个电池单元的电量状况,当出现个别需要放电保持均衡的电池单元时,通过开关矩阵开通对该电池单元放电的电路,放电热量聚集在电阻板处,本装置因为设有隔热板,因而可以实现大电流放电,而无需考虑热量集聚问题,高效完成被动均衡。
为此,本发明提供的技术方案为:
一种被动均衡的汽车电池管理装置,包括:
电池矩阵,所述电池矩阵的一端设置有电连接的正极板,所述正极板上设置有电池控制器,所述电池控制器中集成有控制所述正极板与所述电池矩阵间电连接的开关矩阵,所述电池矩阵的另一端设置有电连接的负极板;
电阻板,其电连接在所述正极板与所述负极板之间,所述电阻板上设置有电光板;以及
隔热板,其设置在所述电池矩阵与所述电阻板之间。
优选的是,所述隔热板采用低导热率的材料制成。
优选的是,所述隔热板的厚度大于2cm。
优选的是,所述隔热板上设有向外侧延伸的弯曲结构,所述弯曲结构包覆所述电阻板的两端。
优选的是,所述弯曲结构上设置有平行于所述电阻板的若干散热管。
优选的是,所述散热管中空。
优选的是,所述散热管上设有若干增加散热面积的散热通孔。
本发明至少包括如下有益效果:
通过电池控制器监控电池矩阵中各个电池单元的电量状况,当出现个别需要放电保持均衡的电池单元时,通过开关矩阵开通对该电池单元放电的电路,放电热量聚集在电阻板处,本装置因为设有隔热板,因而可以实现大电流放电,而无需考虑热量集聚问题,高效完成被动均衡。
