Abstract
A system includes at least one load in a vehicle, a battery electrically connected to the load, a power source electrically connected to the load, and a computer communicatively connected to the power source. The computer is programmed to reduce a voltage supplied by the power source to the load so that the battery discharges to supply power to the load, and then, in response to an electrical quantity of the system being outside an electrical-quantity range while the battery is discharging, perform a minimal risk condition or prevent the vehicle from movably operating.
