Description

采用锂离子电池构成的通用型充电电池及控制方法 技术领域
本发明涉及二次电池或电子电源技术领域,尤其涉及一种采用锂离子电池构成的通用型充电电池及控制方法。
背景技术
锂离子二次电池(以下简称为锂离子电池)具有比能量大、可快速充放电、循环寿命长、自放电小、无公害、无记忆效应等优点,是目前替代通用型一次电池和镍氢充电电池较理想的二次电池。但现有的锂离子电池的输出电压较高,其输出电压随采用正极体系不同而有所差异,目前已商品化的锂离子电池,其标称电压为3.2V~3.8V,且随着锂离子电池技术的发展,锂离子电池的标称电压还会提高,显然锂离子电池不能直接用来替代标称电压为1.5V的通用型电池和标称电压为1.2V的镍氢充电电池。
锂离子电池虽然具有较好的充放电性能,但存在着过充电和过放电耐受性能差、充电过热及放电过热耐受性能差等问题,若控制失当轻则造成锂离子电池快速老化和损坏,重则会产生燃烧甚至爆炸,因而必须严格按照锂离子电池的充放电技术条件控制其充放电工作。
目前已成熟的锂离子电池结构封装工艺主要有四种类型:其一,采取负极集流体与外壳体连接构成的外壳负极封装锂离子电池(通常采用钢质外壳封装);其二,采取正极集流体与外壳体连接构成的外壳正极封装锂离子电池(通常采用铝质外壳封装);其三,采用软包封装的外壳准绝缘封装锂离子电池(通常采用铝塑复合膜材料封装);其四,外壳体采用绝缘封装材料构成的外壳绝缘封装锂离子电池(通常采用聚丙烯及聚乙烯外壳封装)。
由于通用型一次电池和镍氢充电电池的应用历史较长且已标准化,在许多通用电池应用领域,已形成了以电池输出电压检测其低电量的方法,例如:数码相机、MP3、MP4、电子智能锁具、电子仪器仪表等电子装置,均采用检测电池实时输出电压的方法来实现对电池低电量状态的判定。
另,目前个人计算机、平板电脑和手机等产品的普及程度已很高,充电电池采用计算机USB接口、通用型锂离子电池充电适配器作为充电电源,既可降低购置成本又可节约社会资源。
针对上述问题,中国专利局公开了一篇专利申请号为201110219892.0(采用锂离子电池构成的充电电池及控制方法)的专利申请,该申请采取将锂离子电池与放电控制电路封装为一体,构成的通用型充电电池。其存在下列几方面的功能及性能不足问题:
第一、充电电池内部不具有锂离子电池充电控制及充电过热保护
由于充电电池内部未设置锂离子电池充电控制及过热保护电路,因而在充电时必需采取接入二极管来隔离充电及放电电路,并采用带有锂离子电池充电控制电路和温度传感电路的专用外置充电装置进行充电。因而存在下列技术性能缺陷,其一:充电时二极管的正向导通压降会随工作电流和温度的不同而变化,降低了充电控制电路对锂离子电池的检测和充电控制精度,在二极管正向导通压降较高时会产生锂离子电池不能充满的问题,在二极管正向导通压降较低时易产生锂离子电池过充电问题,降低了锂离子电池的充电性能和安全性;其二:由于充电回路接入了隔离二极管,因而抬升了充电电池的充电输入电压,由于现有钴锂体系锂离子电池的充电上限电压已达4.35V且未来还会提高,若采用标称电压为5V±0.25V的现有通用型锂离子电池充电适配器或计算机USB接口给充电电池充电,即使采用正向导通压降较低的肖特基器件,在充电输入电压下限和隔离二极管导通压降上限状态下,仍存在锂离子电池不能完全充满的问题,虽然可以在外置充电装置内采用升压电路解决此问题,但会造成充电装置成本上升、效率及可靠性降低等问题;其三:外置温度传感电路只能通过充电电池的外封装壳体或电极间接检测锂离子电池的温度,降低了锂离子电池充电温度检测精度,使充电电池存在锂离子电池充电过热而降低循环寿命和安全性的问题。
第二、充电电池不具有锂离子电池放电过热保护
在充电电池内部未装置锂离子电池温度传感及控制电路,使得充电电池不具有锂离子电池放电过程的过热保护功能,从而使充电电池在高温环境下高倍率放电时,存在锂离子电池温度超过上限工作温度的风险,因而存在降低锂离子电池循环寿命和安全性的问题。
第三、充放电控制器结构及装配工艺复杂
充放电控制器的负电极与充电电池封装壳体间的电路连接,采用了径向弹性压紧连接结构设计,在充电电池装配时,必须将弹性负电极径向下压到位后,才能将充放电控制器推入充电电池的封装壳体内。此外,弹性负电极为活动部件,其结构占用了较大的充放电控制器内部空间,并使充放电控制器难以实现密封。造成充放电控制器体积较大、制装工艺复杂且 难度较高、不利于自动化量产装配、不能实现防水密封,因而存在充电电池的蓄电容量较低、生产成本较高、受潮及浸水后易产生电路失效的问题。

所述锂离子电池充放电控制电路各工作状态的具体控制方法如下:
充放电模式转换控制方法:在通用型充电电池未接入充电电源状态,单片集成充电电池控制芯片U1的充电电源接入引脚Vcc电压小于4V,单片集成充电电池控制芯片U1关闭充电并开启稳压放电输出,通用型充电电池进入稳压放电状态。在充电电源接入后,单片集成充电电池控制芯片U1的充电电源接入引脚Vcc电压高于4V时,单片集成充电电池控制芯片U1关闭稳压放电输出并开启向锂离子电池LIB充电,通用型充电电池进入充电状态,直至充电电源断电后转换至放电状态后恢复放电输出。此外,通用型充电电池在充电电源脱离后由充电状态转换为放电状态时,单片集成充电电池控制芯片U1的充余电能释放引脚DECO输出为低电平,将第二电容C2在充电时充入的多余电能通过第五电阻R5限流释放,使通用型充电电池的空载电压快速降至最大开路电压,在第二电容C2的电压降至等于或低于最大开路电压后,单片集成充电电池控制芯片U1的充余电能释放引脚DECO输出转换为高阻态。
充电过程控制方法:充电电源接入通用型充电电池后,充电电源的正极与通用型充电电池的正极V+连接,充电电源的负极与通用型充电电池的负极V-连接,由于通用型充电电池的正极V+即为锂离子电池充放电控 制电路的V+端,通用型充电电池的负极V-即为锂离子电池充放电控制电路的V-端,就等于充电电源的正极连接至单片集成充电电池控制芯片U1的充电电源输入引脚Vcc、充电电源的负极连接至单片集成充电电池控制芯片U1的电源地引脚GND,此时若锂离子电池LIB的温度低于TCH,单片集成充电电池控制芯片U1开启对锂离子电池LIB充电,单片集成充电电池控制芯片U1通过锂离子电池接入引脚BAT检测锂离子电池LIB的输出电压VLIB,并根据VLIB的状态由锂离子电池接入引脚BAT输出对锂离子电池LIB充电,当锂离子电池LIB的输出电压VLIB等于或小于锂离子电池LIB放电截止电压VD(VLIB≤VD)时,单片集成充电电池控制芯片U1对锂离子电池LIB进行涓流充电,当锂离子电池LIB的输出电压VLIB大于锂离子电池LIB的放电截止电压VD但小于锂离子电池LIB的充电上限电压VH(VD<VLIB<VH)时,单片集成充电电池控制芯片U1以ICHG对锂离子电池LIB进行恒流充电,当锂离子电池LIB的输出电压VLIB等于锂离子电池LIB的充电上限电压VH(VLIB=VH)时,单片集成充电电池控制芯片U1以充电上限电压VH对锂离子电池LIB进行恒压充电,直至充电电流降至ICHG/10后停止充电。在充电过程中发光二极管D1由充电电源供电,并由单片集成充电电池控制芯片U1通过充电状态输出引脚LDD驱动显示充电过程的工作状态。
充电电流控制方法:单片集成充电电池控制芯片U1向锂离子电池LIB充电的恒流态最大充电电流由第四电阻R4的电阻值设定,即R4=1000V/ICHG(ICHG为单片集成充电电池控制芯片U1在恒流充电状态输出的最大充电电流),单片集成充电电池控制芯片U1的锂离子电池LIB充满态判定电流为ICHG/10。
充电电源输出电流适配控制方法:单片集成充电电池控制芯片U1通过充电电源接入引脚Vcc,检测充电电源的空载状态输出电压和线性加载状态输出电压的压降幅值,判定充电电源的允许输出的最大电流,在充电电源允许输出的最大电流小于ICHG时,单片集成充电电池控制芯片U1以充电电源允许输出的最大电流为限流值对锂离子电池LIB进行充电。
稳压输出电压控制方法:在通用型充电电池未接入充电电源的放电状态,单片集成充电电池控制芯片U1通过锂离子电池接入引脚BAT检测锂离子电池LIB的输出电压VLIB,当锂离子电池LIB的输出电压VLIB高于低电量电压(VLIB>VL)时,单片集成充电电池控制芯片U1将锂离子电池LIB输出电压降为1.5V稳压输出。当锂离子电池LIB输出电压VLIB等于或低于低电量电压(VLIB≤VL)时,单片集成充电电池控制芯片U1将 锂离子电池LIB输出电压降为1.1V稳压输出。单片集成充电电池控制芯片U1对锂离子电池LIB的低电量电压VL的检测判定值为多点采样均值,其采样频率与锂离子电池LIB的输出电压变化率成正比,其检测门限的回差电压为△V1,因而在锂离子电池LIB充电后的电压VLIB升至等于或高于VL+△V1后,单片集成充电电池控制芯片U1恢复1.5V稳压输出。
过放电保护方法:在通用型充电电池未接入充电电源的放电状态,单片集成充电电池控制芯片U1通过锂离子电池接入引脚BAT检测锂离子电池LIB的输出电压VLIB,在锂离子电池LIB的输出电压VLIB高于放电截止电压(VLIB>VD)时,单片集成充电电池控制芯片U1开启稳压输出。在锂离子电池LIB的输出电压VLIB等于或低于放电截止电压(VLIB≤VD)时,单片集成充电电池控制芯片U1关闭稳压输出。单片集成充电电池控制芯片U1对锂离子电池LIB的放电截止电压VD的检测判定值为多点采样均值,其采样频率与锂离子电池LIB的输出电压变化率成正比,其检测门限的回差电压为△V2,因而在锂离子电池LIB充电后的输出电压VLIB升至等于或高于VD+△V2后,单片集成充电电池控制芯片U1恢复稳压输出。
输出过载或短路控制方法:单片集成充电电池控制芯片U1设有可设定限流值的输出过载保护电路,在通用型充电电池输出过载或短路时,单片集成充电电池控制芯片U1按其设定的最大输出电流ILIM为限流值稳压输出。单片集成充电电池控制芯片U1的稳压输出限流值通过单片集成充电电池控制芯片U1的放电电流设置引脚IOSET的接入电平状态设定,将单片集成充电电池控制芯片U1的放电电流设置引脚IOSET接至单片集成充电电池控制芯片U1的锂离子电池接入引脚BAT时,单片集成充电电池控制芯片U1的最大输出电流ILIM为2A,将单片集成充电电池控制芯片U1的放电电流设置引脚IOSET接至单片集成充电电池控制芯片U1的电源地引脚GND时,单片集成充电电池控制芯片U1的最大输出电流ILIM为1A。按照通用型充电电池配用的锂离子电池的放电倍率特性配置单片集成充电电池控制芯片U1的最大输出电流ILIM,避免通用型充电电池输出过载或短路时锂离子电池LIB超倍率放电损伤。
充电过热保护控制方法:单片集成充电电池控制芯片U1的NTC电压检测引脚NTC的门限电压为0.3VLIB,在充电状态,单片集成充电电池控制芯片U1的温度检测设置引脚DTCS输出为高阻态,第一电阻R1、第二电阻R2和负温度系数热敏电阻Rt的电阻值需满足:2.33Rtch=R1+R2(Rtch为负温度系数热敏电阻Rt在锂离子电池温度等于TCH时的电阻 值)。在锂离子电池LIB工作温度低于设定的充电上限温度TCH时,单片集成充电电池控制芯片U1的NTC电压检测引脚NTC的电压高于0.3VLIB,单片集成充电电池控制芯片U1开启向锂离子电池LIB充电。在锂离子电池LIB工作温度上升至等于或高于充电上限温度TCH时,单片集成充电电池控制芯片U1的NTC电压检测引脚NTC的电压等于或低于0.3VLIB,单片集成充电电池控制芯片U1关闭向锂离子电池LIB充电。单片集成充电电池控制芯片U1的NTC电压检测门限的回差电压为△VT,因而在锂离子电池LIB工作温度降至使单片集成充电电池控制芯片U1的NTC电压检测引脚NTC的电压等于或高于0.3VLIB+△VT时,单片集成充电电池控制芯片U1恢复向锂离子电池LIB充电。
放电过热保护控制方法:单片集成充电电池控制芯片U1的NTC电压检测引脚NTC的门限电压为0.3VLIB,在放电状态,单片集成充电电池控制芯片U1将温度检测设置引脚DTCS接至单片集成充电电池控制芯片U1的锂离子电池接入引脚BAT,第二电阻R2和负温度系数热敏电阻Rt的电阻值需满足:2.33Rtdh=R2(Rtdh为负温度系数热敏电阻Rt在锂离子电池温度等于TDH时的电阻值)。在锂离子电池LIB工作温度低于放电上限温度TDH时,单片集成充电电池控制芯片U1的NTC电压检测引脚NTC电压高于0.3VLIB,单片集成充电电池控制芯片U1开启稳压输出。在锂离子电池LIB工作温度上升至等于或高于放电上限温度TDH时,单片集成充电电池控制芯片U1的NTC电压检测引脚NTC电压等于或低于0.3VLIB,单片集成充电电池控制芯片U1关闭稳压输出。单片集成充电电池控制芯片U1的NTC电压检测门限的回差电压为△VT,因而在锂离子电池LIB停止放电后的工作温度降至使单片集成充电电池控制芯片U1的NTC电压检测引脚NTC的电压等于或高于0.3VLIB+△VT时,单片集成充电电池控制芯片U1恢复稳压输出。
