The application discloses a kind of vehicle
power battery power test method and
system based on power MAP table, it is related to
power battery power test technical field, comprising: according to the imported power MAP table, identify multiple temperature and SOC state test points in table, and determine the nature parameter of
power test;Combining the selected set constant volume mode, the power of vehicle
power battery to be measured is tested;Wherein, multiple temperature test points are tested in the order from high temperature to low temperature, and according to the difference of charge-
discharge operation mode, multiple SOC state test points are tested in different order;Based on the data obtained by testing and power MAP table
original data, the key data of each MAP
test point, the
capacity value under each temperature, the adjustment
capacity value in each test step and the running
capacity value are obtained.The application can effectively detect the
power capability of power battery and its
system, improve detection efficiency and precision.
