The invention provides a large-current charging control method and device, a vehicle and a storage medium, and belongs to the technical field of vehicle charging control. The method comprises the steps that when the vehicle is in a charging state, the historical running state, the current battery electric quantity and the current environment temperature of the vehicle are obtained; acquiring a preset charging duration, and determining whether to correct the charging current based on the current battery electric quantity and the preset charging duration; when it is determined that the charging current is corrected, a charging current correction coefficient is determined based on the historical operation state and the current environment temperature; correcting the preset charging current based on the charging current correction coefficient to obtain a corrected charging current, and charging the vehicle based on the corrected charging current; wherein the temperature of the high-voltage connection system in charging the vehicle based on the corrected charging current is less than a safe temperature threshold. It is ensured that the temperature of the high-voltage connection system is smaller than the safety temperature threshold value when the vehicle is charged, and the safety of the whole vehicle is improved.
