The invention provides a charging management method and device for a vehicle-mounted battery. The new energy vehicle comprises a vehicle-mounted battery, a vehicle-mounted charger and an electric heater. The method comprises the steps that the target temperature and the residual battery capacity of the vehicle-mounted battery are acquired, and the output power of the vehicle-mounted charger and the output power of the electric heater are acquired; determining a first temperature threshold based on the target temperature and the residual battery capacity, and determining a second temperature threshold based on the output power of the vehicle-mounted charger; based on the difference between the output power of the vehicle-mounted charger and the output power of the electric heater and the environment temperature corresponding to the new energy vehicle, the first temperature threshold value and the second temperature threshold value are corrected, and a corrected third temperature threshold value and a corrected fourth temperature threshold value are obtained; and managing the charging of the vehicle-mounted battery based on the third temperature threshold value and the fourth temperature threshold value.
