www.sbsbattery.comas the effects of temperature, state of charge and type of circuit protection device are also presented. ... To measure the effect of state of charge (SOC%), similar “dead short” tests were conducted on a set of nine UPS12-170 batteries (12V-50AH). Individual batteries were constant current discharged at the 5 hour rate (8.66A) for 0, 1.25 ...

www.analog.comto measure the state of charge (SOC) of the cells, which is defined as the available capacity (in Ah) and expressed as a percentage of its rated capacity. The SOC parameter can be viewed as a thermodynamic quantity enabling one to assess the potential energy of a battery. It is
Battery Cell Balancing: What to Balance and How
www.ti.comdirect correlation with chemical state of charge. Note that while % SOC unbalance remains constant during entire discharge, voltage differences between the cells vary with state of charge because dV/dSOC varies with SOC. Fig 1 shows OCV differences between the cells at constant SOC unbalance but at different states of charge.

Proper diagnosis of charging system problems requires a thorough understanding of the system components and their operation. Operation When the engine is running, battery power energizes the charging system and engine power drives it.
