Embodiments discussed herein refer to backwards compatible charging circuits and methods for charging a battery to a relatively high voltage level regardless of whether the charging station is capable of supplying power at that relatively high voltage level. The circuitry and methods according to embodiments discussed herein can use the onboard charging system to provide a voltage boosting path to increase the charge voltage from a legacy voltage level (e.g., a relatively low voltage level) to a native voltage level (e.g., a relatively high voltage level). When a native voltage charging station is charging the battery, the circuitry and methods according to embodiments discussed herein can use a native voltage path for supplying power, received from the charging station at the native voltage, to the battery.
