A vehicle power system includes a vehicle control module configured to control multiple electronic components of a vehicle, a power supply including an input coupled to receive input power from a system power source and an output coupled to supply power to the vehicle control module, and an energy reserve circuit electrically coupled with a node defined between the system power source and the power supply. The energy reserve circuit is configured to store energy to supply power to the power supply in response to a reduction in power supplied by the system power source below a threshold value. The system includes a charging circuit coupled between the energy reserve circuit and an electrical ground, the charging circuit configured to charge the energy reserve circuit with a constant current value.
