Abstract
An insulation monitoring method and system for a traction battery and an apparatus are proposed to solve the problem of how to accurately predict a risk of insulation deterioration of the traction battery before the insulation deterioration occurs on the traction battery, so as to provide an early warning about failures in the traction battery. In this method, data statistics on a large amount of insulation resistance values within a long period of time are collected, and whether the traction battery has the risk of insulation deterioration is determined by analysis based on a data statistical result; and if the traction battery has the risk of insulation deterioration, alarm information is output. In this method, based on data statistical analysis performed on the large amount of insulation resistance values within a long period of time, insulation deterioration can be predicted before the insulation deterioration occurs on the traction battery. This allows a user to perform battery maintenance in time before the insulation deterioration occurs on the traction battery, so as to prevent traction battery failures.
