A controller may include input channels configured to receive charge acceptance values of an auxiliary battery and an SOC of a traction battery. The controller may also include output channels configured to provide threshold signals to set a voltage threshold of an auxiliary bus coupled with the auxiliary battery and deriving power from the traction battery. The controller may include control logic configured to generate the threshold signals such that during a next charging event, a voltage of the auxiliary battery achieves a desulfation value. The controller logic may generate the threshold signals in response to the acceptance falling below a predetermined sulfation value and the SOC being above an SOC threshold.
