The invention relates to an electric automobile battery pack and automobile high voltage system matching method. The method comprises the steps that 1, a preset number of lithium ion batteries are connected in series to form standard battery packs; 2, the lowest reserve electric quantity of an electric automobile is determined according to the grade of the electric automobile; 3, according to the reserve electric quantity of the electric automobile and the automobile wheel track and wheel base limit, the number of the battery packs is determined; 4, according to the voltage grade of the electric automobile high voltage system, the voltage of a power battery pack is determined; 5, according to the voltage of the power battery pack determined in the step 4, the connection way between the fixed number of standard battery packs is determined; 6, the fixed number of standard battery packs form the power battery pack in the connection mode determined in the step 5. According to the matching method, the power battery pack is matched with the electric automobile with various wheel tracks and wheel bases in the structure, and matched with the electric automobile with different automobile high voltage system voltage grades in voltage.
