The invention discloses a vehicle battery internal resistance monitoring method and device, and relates to the technical field of vehicle battery monitoring, and the method comprises the steps: obtaining first battery information comprising a first charging current value and a first voltage value of a battery when the vehicle detects that the battery in the vehicle is charged to a preset charge state by using the first charging current value, the preset state of charge is the corresponding state of charge of the battery in the platform period; the vehicle controls the battery to be charged at a second charging current value different from the first charging current value in the platform period; when it is monitored that the second charging current value is used for charging the battery, second battery information including the second charging current value, a second voltage value of the battery, the real-time temperature of the battery and the number of times of charging of the battery is obtained; and sending the first battery information and the second battery information to a server, so that the server evaluates the health state of the battery according to the first battery information and the second battery information. The detection process of the battery can be simplified.
