在我的应用场景中,使用3串2并锂聚合物电芯,但受限于结构设计的原因。整个电池被分成两个3串的单元,这两个单元再通过约10厘米的导线并联,然后接入基于BQ40Z50的保护板(如图所示)。请问这种做法是否会影响电量估算的精度?会产生多大的影响?

您好,请参考下面内容
Depending on the trace resistances and the load magnitude it could impact the accuracy, but if a learning cycle is performed on the pack itself the impact should be minimal. NTCs should not be shared, so I assume this connection may not be accurate (1 NTC for each battery is preferred).
