Abstract: The disclosed embodiments provide a system that manages use of a battery in a portable electronic device. During operation, the system operates a charging circuit for converting an input voltage from a power source into a set of output voltages for charging the battery and powering a low-voltage subsystem and a high-voltage subsystem in the portable electronic device. Upon detecting the input voltage from the power source and a low-voltage state in the battery during operation of the charging circuit, the system uses a first inductor group in the charging circuit to down-convert the input voltage to a target voltage of the battery that is lower than a voltage requirement of the high-voltage subsystem. The system also uses a second inductor group in the charging circuit to up-convert the target voltage to power the high-voltage subsystem.

In order to balance out the individual states of charge (SOCn) of the n=1 to N cells, the state of charge of at least one cell is changed to a target state of charge (SOCtarget,n) which depends on the discharge depth (DODk) of the cell having the lowest capacity (Capk) according to the equation SOCtarget,n=1?DODk/Capn, Capn being the capacity of the nth cell to be changed. Advantageously, the method is suitable for optimizing the voltage or the energy content of a battery that is constituted of a plurality of cells.

Abstract: Kelvin (4-wire) connecting cables are routinely used when performing dynamic measurements (i.e., measurements with time-varying signals) on electrochemical cells and batteries. Current-carrying and voltage-sensing conductor pairs within such cables comprise distributed-parameter two-wire transmission lines which may extend several meters in length. As with all such transmission lines, internally reflected waves can oscillate back and forth at high frequency (hf) whenever the lines are not terminated in their characteristic impedances. Such hf reflected waves, by interacting with measuring circuitry, can seriously degrade low-frequency measurement accuracy. Apparatus is disclosed herein that suppresses hf reflected waves oscillating on Kelvin connecting cables during dynamic measurements of cells and batteries.
