One embodiment of the present disclosure describes a system and method for reducing errors in a battery model (42) used in operation of a battery control system (14). The battery control system (14) may operate based on a modeled response of the battery derived from the battery model (42). If the battery model (42) is not calibrated/validated, errors in the battery model (42) may be propagated through a modeled response of the battery to operation of the battery control system (14). The calibration current pulse may result in a measured response of the battery that is different than a modeled response of the battery to the same calibration current pulse. A verification technique (80) may protect the battery control system (42) from errors from an uncalibrated battery model using a difference between a modeled response of the battery to the calibration current pulse (88) and a measured response as a method of calibrating the battery model (42).
本公开的一个实施例描述了用于减少在电池控制系统(14)的运行中使用的电池模型(42)中的误差的系统及方法。电池控制系统(14)可以基于从电池模型(42)导出的电池的模型化的响应来运行。如果电池模型(42)未被校准/验证,则电池模型(42)中的误差可以通过电池的模型化的响应传播到电池控制系统(14)的运行。校准电流脉冲可导致电池的与电池对相同校准电流脉冲的模型化响应不同的测得响应。验证技术(80)可以保护电池控制系统(42)不受来自未校准电池模型的误差影响,所述验证技术使用电池对校准电流脉冲(88)的模型化响应和测得的响应之间的差异作为校准电池模型(42)的方法。
