NXP MCU FS32K144 based BMS solution
With the widespread use of new energy electric vehicles, the capacity, safety, health status and range of the battery are becoming more and more important concerns. The battery management system is a system to monitor and control the battery, providing real-time feedback to the user with the collected battery information.
When managing multiple batteries, it requires personnel to debug and set up on site, which makes it quite inconvenient to check, maintain and update. Moreover, information on the working performance, battery aging condition and service life of the battery pack requires personnel to obtain it on site after repeated debugging and experiments, which is quite tedious and time-consuming. Moreover, during the production, debugging or experiments, only when the battery has problems affecting the work of the electric vehicle, will the fault be found and the battery be replaced.
This approach is blind, lagging and quite easy to produce undesirable consequences, seriously leading to production work delays and dangerous production accidents. the BMS battery management system is of great importance to protect electric vehicles, charging station equipment and personnel safety.
