【应用】采用瑞萨锂离子电池管理模拟前端IC ISL94208轻松实现串联电池组的电池均衡

技术问答

锂离子电池具有能量密度高、循环寿命高、无污染、无记忆效应、充电速度快等优点，被广泛应用于电动汽车、电动自行车、便携式电工工具、医疗仪器、智能手机等产品上，但是锂离子电池存在一定的安全隐患，易燃烧易爆炸，往往需要外部监测和保护电路，测量其端电压、电流、温度，估算其SOC、SOH等，防止其过充过放过热，导致燃烧爆炸。瑞萨RENESAS推出的锂离子电池管理模拟前端IC ISL94208，能够管理4~6单体锂离子电池（或4~6串并联锂离子电池组），具备过流保护、短路监控、电池均衡、过热自动切断主回路等功能。

锂离子电池的端电压较低，通常不超过4.2V，放电平台一般在3.2～3.7V，在通常的应用中，锂离子电池串联连接提高电压，组成一个串联连接的电池包对外供电。串联电池包中单体电池（组）的不匹配，会降低电池包整体可利用容量。电池包的不匹配主要有两种，SOC（荷电状态）不匹配和容量不匹配。

SOC不匹配：电池包所有串联单体电池（组）具有相同的容量，但是它们的SOC不相同，可能的原因是电池初始SOC不相同，经过无效的充放电循环，电池损坏等。

容量不匹配：电池包所有串联单体电池（组）具有不同的容量，在充放电过程中最终导致SOC不匹配，影响电池包总体容量利用。

容量不匹配均衡难度较大，实际使用中尽量避免，电池包成组通常都采用相同容量的电池。串联电池组成组之前，通过单独充放电的方式将单体电池的SOC保持相同值，成组后需要估算单体电池SOC，当发现各单体电池SOC差别较大时，启动较大SOC的均衡电路，通过外电路将能量释放，以达到SOC一致的目的。这种将能量释放的均衡方法被叫做被动均衡，这种均衡一般在充电过程中完成。通常SOC估算采用开路电压法。瑞萨推出的锂离子电池管理模拟前端IC ISL94208具备这种均衡管理的功能，如图1所示为ISL94208采用内部MOSFET的均衡电路原理图。

图1 ISL94208采用内部MOSFET的均衡电路原理图

如图1所示，ISL94208有专门的寄存器用于管理对应的均衡MOSFET，当芯片检测到某些单体电池的端电压大于与其他的端电压，且差值超过了设定的阈值时，芯片将自动开启对应的均衡MOSFET，此单体电池将通过外部电阻、内部均衡MOSFET形成放电回路，或者在充电过程中，将一部分充电电流旁路到MOSFET，而对应的电池的充电电流将小于其他电池，它的充电功率更小，最终保持所有电池的SOC同步到达100%。ISL94208内部均衡MOSFET最大电流为200mA，选择合适的外部电阻来限制均衡电流，图1中所示选择21Ω电阻，最高电池电压为4.2V，假设内部MOSFET导通电阻为0Ω，最大均衡电流为200mA，电阻功耗为0.84W，可选择1W的电阻，实际内部MOSFET的导通电阻大约为7Ω，此时实际最大均衡电流为150mA，内部MOSFET功耗为158mW，ISL94208整体功耗限制在400mW，所以可同时均衡的电池数量被限制在最多2个。

对于电池容量较大的电池组串联成电池包时，我们可能需要更高的均衡能力，需要增大均衡电流，那么我们可以采用外部连接P型MOSFET的方式实现，如图2所示。当ISL94208检测到某些电池需要均衡时，通过开通内部均衡MOSFET，将对应CBx引脚电位拉低，外部P型MOSFET导通，电池经10Ω外部电阻，P型MOSFET放电或者旁路。可根据需要的均衡电流选择合适的P型MOSFET和电阻。图2所示，如果希望达到400mA的均衡电流，P型MOSFET的导通电阻应小于0.5Ω，外部10Ω电阻功耗为1.6W，留有一定余量，选择3～5W的电阻。

图2 ISL94208采用外部P型MOSFET的均衡电路原理图

电池均衡对电池包的使用是否有益处呢？我们来看一组对比充放电曲线。图3为串联电池包中的两组电池没有均衡的充放电SOC曲线，图4为串联电池包中的两组电池有均衡的充放电SOC曲线。两组电池具有同样的容量，同样的型号，同一厂家生产，初始SOC相同，电池组Cell2存在软短路，内阻大约40000Ω，放置3个月自放电导致SOC降低3%。如图3所示，软短路导致它们的充放电SOC曲线不一致，Cell2总是先放电终止，且不能充满电，导致12个月后可利用容量只有出厂容量的64%，图4所示，对两组电池增加均衡功能后，尽管存在软短路，放电过程中SOC曲线不能一致，但是每次充电过程中，通过电池均衡技术，可以使两组电池都能完全充满电，放置3个月后也只是损失了出厂容量的9%。
