AI Technical Summary

Problems solved by technology

If the temperature monitoring of a single battery is not accurate enough, different heat generation will lead to uneven current distribution in parallel connected batteries, resulting in accelerated battery aging
In the worst case, this could lead to thermal runaway, causing the EV to spontaneously ignite

Description

technical field [0001] The invention relates to an electric vehicle battery monitoring system, in particular to a PLC-based electric vehicle battery intelligent monitoring system and method. Background technique [0002] Now that electric vehicles have been popularized, electric vehicle batteries are a key component of electric vehicles, and the performance of batteries has become a top priority. However, as the battery life of electric vehicles continues to increase, the performance and safety of the battery system are put to the test. For example, the temperature uniformity of the battery is poor; the thermal management efficiency is low; the aging of the battery and other problems. At present, the battery monitoring of electric vehicles still uses traditional sensors, and the remote monitoring system of electric vehicle batteries based on CAN bus is adopted. [0003] Electric vehicle batteries based on technologies such as CAN are too costly, heavy in weight, large in p...
