摘要： Non-sequential monitoring of battery cells in battery monitoring systems, and related components, systems, and methods are disclosed. In one embodiment, a battery monitoring system control unit is provided. The battery monitoring system control unit is configured to control battery monitoring devices. Each battery monitoring device is configured to be coupled to a subset of battery cells electrically connected in series in a sequential order to form a battery. The battery monitoring system control unit is further configured to instruct the battery monitoring devices to test an ohmic value of each battery cell of the battery cells of the battery in a non-sequential order. In this manner, heat generated in the battery monitoring devices from the testing may be more effectively dissipated, which can also allow for the battery monitoring devices to be employed in higher operating temperature environments.

摘要： Reducing or avoiding noise in measured signals of a tested battery cell(s) in a battery power system is disclosed. A battery monitoring device(s) coupled to a tested battery cell(s) applies test current pulses at a predetermined frequency to place an effective alternating current (AC) load on the tested battery cell(s). The resulting AC voltage signal generated across the tested battery cell(s) is sampled at the frequency of the test current to convert the AC voltage signal to a direct current (DC) voltage signal to be measured to determine the state-of-health of the tested battery cell(s). To avoid or reduce noise in the DC voltage signal, a noise spectrum of noise signals at defined frequencies induced on the tested battery cell(s) is determined. The battery monitoring device sets the frequency of the test current pulse at a determined reduced-noise frequency to avoid noise signals being present in the DC voltage signal.
