The invention provides an electric vehicle charging current determination method and device, a storage medium and a vehicle, and belongs to the technical field of vehicles. According to the embodiment of the invention, the charging current upper limit threshold value and the charging current lower limit threshold value of the battery are determined based on the charging side performance parameter of the charging equipment, the battery side performance parameter of the battery and the high-voltage accessory consumption current of the vehicle; and adjusting the initial request charging current of the battery to obtain a battery charging current, and finally determining a target request charging current requested from the charging device based on the battery charging current and the high-voltage accessory consumption current. According to the embodiment of the invention, the influence of the current consumed by the high-voltage accessory on the charging of the battery can be eliminated, the charging requirement of the battery is fully met, the charging rate is improved, the battery charging current finally reaching the battery can be limited in a safe and reasonable current threshold range, and the charging safety of the battery is effectively ensured.
