【选型】电流检测方式电阻采样和霍尔采样的优劣比较
现阶段,在汽车工业上电流检测技术比较流行的有两种,一种是采样大功率精密电阻来进行电流采样,通过运放电路输入到MCU的检测方法(简称电阻采样方式),另一种是采样霍尔传感器方式,通过霍尔电流传感器输出的电压信号,经过处理后输入到MCU的检测方法(简称霍尔采样方式)。
电阻采样方式
电阻采样方式的原理很简单,就是欧姆定律,I=U/R。
霍尔采样方式
霍尔采样方式的原理也比较简单,就是霍尔效应。

从上图可以看出电阻采样方式的最大优点就是成本低,适用性好,可以根据不同情况来设计自己的电路,达到最佳效果。还有,低阻(小于1mΩ)的金属合金检流电阻的抗浪涌能力非常好,在出现短路和过流情况时,能实现可靠的保护。但是其缺点最主要的是大功率精密电阻的温漂很严重,在一些特定应用场合不适用。另外,采用电阻采样有一定的功率损耗。
霍尔采样方式的优点是能测量大电流,而且功率耗散小。然而,这种方法也有不少缺点,限制其使用,对小量程的电流进行测量时,要求使用大偏置电压,这会引起误差;易受外部磁场的影响;对ESD敏感;成本高,体积大。
因此,如何选择一种电流检测方式,要根据具体的设计方案来试行。两种方法均有其优点和缺点,这些因素都要在设计中加以仔细考量。目前,随着精密电阻的发展,温漂越做来越小,电阻采样的方式逐渐在汽车工业中比例越来越大。以新能源汽车中的BMS为例,为了控制电池总电流输出,必须时时监测总电流的大小。因电池的设计结构和空间布局,采用ISA的BAS系列电阻显然具体更大的优势,方便布局及设计自己需要的电路。
ISA(ISABELLENHUETTE)的产品线很多,如何选择合适的一款产品很重要。首先,需要确定是否10Ω以下的应用,这样才是有意义的采样电阻。然后确认是常规的SMD安装还是机械安装。SMD安装部分,大于5mΩ的主选VMX和Cx系列,小于5mΩ的主选BVx系列。机械安装一般推荐选用BAS系列,如果有特别需求的,ISA可以按客户的需要,提供定制方案。
最后,提及一下,世强有代理ISA的精密电阻全部产品线。ISA目前是世界先进的精密微阻值电阻制造厂商,阻值从100uΩ到100Ω,可以测试1mA到1500A的电流,主要产品的温漂都在50ppm以下,更有20ppm和1ppm以下等级的产品,能极大的减少因测试中温漂引起的差异。
