A battery system for an electric vehicle, comprising: at least one battery cell configured to store an electrical charge for powering the electric vehicle; a high voltage bus electrically coupled with the at least one battery; a DC-DC converter electrically coupled to the battery cell; a low voltage bus electrically connected between the DC-DC converter and the at least one vehicle electrical component; and a battery cell monitor electrically coupled with the at least one battery cell and the DC-DC converter, where the battery cell monitor includes a current sensor configured to detect a current from the at least one battery cell to the DC-DC converter. The battery cell monitor includes a controller configured to estimate a state of charge of the at least one battery cell as a function of the current detected by the current sensor, and adjust a switching operation of the DC-DC converter as a function of the current detected by the current sensor.
