A charging method is provided, which includes: acquiring a state parameter of a traction battery (121), the state parameter including a battery temperature; sending first charging mode demand information to a charging pile (110) when the battery temperature is lower than a first preset threshold, where the first charging mode demand information is used for indicating a pulse charging mode, the pulse charging mode is a charging mode using a pulsed voltage or a pulsed current, and the pulsed voltage or the pulsed current is used for charging the traction battery (121). According to the technical solution of the embodiment of the application, the battery management system (122) acquires the battery temperature of the traction battery (121), when the battery temperature is low, for example, when the battery temperature is lower than the first preset threshold, first charging mode demand information indicating a pulse charging mode is sent to the charging pile (110), and in the pulse charging mode, the charging pile (110) can output pulse current to charge the traction battery (121), so as to prevent the performance of the traction battery (121) from being affected by directly charging the traction battery (121) at a low temperature, thereby ensuring the performance of the traction battery (121).
