The invention discloses a charging method and a charging device. The method comprises the following steps of starting an intermittent charging mode when detecting that the voltage of a battery reaches rated voltage in a constant-current charging process; carrying out intermittent charging and detecting the voltage of the battery in a charging clearance under an intermittent charging mode; and starting a constant-voltage charging mode when detecting that the voltage of the battery reaches the rated voltage in the intermittent charging process, wherein the charging current under the intermittent charging mode is greater than that under the constant-voltage charging mode. Charging is suspended during voltage detection in the intermittent charging process, so that the problem that the voltage of a detection point is inconsistent with the voltage of a battery core in the battery due to a voltage drop on an equivalent resistor in the battery is solved; the condition of entering the constant-voltage charging mode only when the voltage of the battery core of the battery really reaches the rated voltage can be ensured, the problem that the charging time is prolonged due to entering the constant-voltage charging mode of which the charging current is continuously reduced is solved and the charging rate is improved.
