CHARGING METHOD, BATTERY MANAGEMENT SYSTEM OF TRACTION BATTERY AND CHARGING PILE

Embodiments of the present application provide a charging method, a battery management system for a traction battery and a charging pile, which can effectively ensure normal charging of an electric vehicle. The charging method is used for charging a traction battery, and the method includes: determining, by the battery management system (BMS) of the traction battery, a pulse charging demand parameter according to a battery state parameter of the traction battery; and sending a pulse charging information to a charging pile by the BMS, the pulse charging information including the pulse charging demand parameter for indicating the charging pile to output a pulse current for charging the traction battery.
