A method for charging a traction battery of a vehicle at a stationary charging column includes having the vehicle charging controller register a charging process to the charging column charging controller with a high voltage value of the traction battery as a requested maximum charging voltage. The charging column charging controller then performs an insulation test at an insulation test voltage that corresponds to the requested maximum charging voltage or to the maximum charging column voltage when the latter is lower than the requested maximum charging voltage. The insulation test voltage is measured by a vehicle voltmeter. If the measured insulation test voltage corresponds to the lower voltage value, the vehicle charging controller registers a charging process to the charging column charging controller with the low voltage value as new requested charging voltage and sets the charging voltage adapter to a charging column voltage corresponding to the low voltage value.
