高压动力电池包由若干个串联的电池单体组成,由于电池制造工艺的差异性,电池单体之间性能存在一定的差异性;电池在使用过程中,由于周围环境的不同,将增大电池单体的不一致性,从而降低电池***的工作效率,缩短电池的寿命。
为延长电池寿命,增加电池充放电效率,混合动力高压动力电池使用一段时间后,需要对电池做均衡化充电维护。
现有的电池均衡化充电维护一般采用能量转移法或能量消耗法,其实现原理是管理***监测各电池单体的电压,如果电池单体间电压差超过允许的范围,管理***控制继电器,控制放电电阻或电容与需要均衡化的电池单体连接,从而实现对电池单体的能量消耗或转移,达到电池单体均衡化的目的,但这种电池单体均衡化方法成本高,需要消耗一定的能量,增加了机械设计和电池***热管理的难度。

2、一种实现前述方法的混合动力车动力电池的智能化均衡充电装置,其特征在于:具有电脑、程控充电器,其中电脑接电池管理***信号输出端,电脑信号输出端接程控充电器,程控充电器接电池本体。
3、一种实现前述方法的混合动力车动力电池的智能化均衡充电装置,其特征在于:具有充电控制器和充电器,其中充电控制器的信号输出端接充电器,充电控制器接电池管理***信号输出端,充电器接电池本体。
本发明具有的有益效果:
本发明通过对动力电池过充,实现对动力电池的均衡化维护,不需要改变电池***结构或增加其它额外的器件,使动力电池的均衡化充电维护更加方便。
附图说明
图1为本发明实施例1的结构框图;
图2为本发明实施例2的结构框图。
具体实施方式
实施例1:如图1所示,具有电脑、程控充电器,其中电脑接电池管理***信号输出端,电脑信号输出端接程控充电器,程控充电器接电池本体。电池管理***将均衡充电请求、动力电池SOC值信号传送至电脑。
电池管理***具有均衡化充电预测功能,电池管理***负责预测电池是否需要进行均衡化充电,当预测到电池需要进行均衡化充电,电池管理***向发送均衡化充电请求。
该方案适用于已有程控充电设备的用户,只需增加软件控制,即可建立智能均衡化充电***,可降低用户的购置设备的成本。
实施例2:如图2所示,具有充电控制器和充电器,充电控制器和充电器构成独立的充电***,其中充电控制器的信号输出端接充电器,充电控制器接电池管理***信号输出端,充电器接电池本体。电池管理***将均衡充电请求、动力电池SOC值信号传送至充电控制器。
电池管理***具有均衡化充电预测功能,电池管理***负责预测电池是否需要进行均衡化充电,当预测到电池需要进行均衡化充电,电池管理***向发送均衡化充电请求。
动力电池均衡化充电步骤如下:
a、动力电池管理***向电脑或充电控制器发出电池均衡充电请求;
b、程控充电器或充电器对动力电池进行充电,充电至动力电池SOC值达到100%;
c、以小电流对动力电池继续充电,充电时间控制在安全时间内。
在步骤b中,先用大电流对动力电池进行充电,当动力电池SOC值达到高值时,用小电流对动力电池进行恒流充电。所说的动力电池SOC值达到高值,是指电池SOC值达到90%-95%;所说的小电流是指电流小于1A-2A。
这样,电量多的电池单体接收电量少,电量少的电池单体接收的电量多,随着过充电时间的增加,电池单体的电量差异性降低,从而实现电池单体的均衡化维护。
