The invention discloses a vehicle battery charging control method and system, and relates to the field of automobiles. The method comprises the steps that an interactive charging system obtains available data; calculating to obtain available charging current; obtaining a first weight value, obtaining a second weight value, and obtaining a third weight value by taking the minimum value of the first weight value and the second weight value; multiplying the available charging current by a third weight to obtain a set charging current; based on the battery temperature and the SOC, battery internal resistance is obtained, the battery internal resistance is multiplied by the set charging current, and battery internal resistance voltage is obtained; obtaining an OCV voltage, and obtaining a corrected battery total voltage; acquiring a corresponding preset voltage difference voltage window value, and adding the corrected battery total voltage to the preset voltage difference voltage window value to acquire a limited charging voltage; and sending the set charging current and the limited charging voltage as control signals to the charger. The technical problem that it is difficult to monitor the battery state in real time in the prior art is solved, and the technical effect of safe and efficient battery charging is achieved.
