Validation of Wireless Battery Management System (wBMS) – Gen2

Abstract

Wireless Battery Management System (wBMS) is a primary enabler for the widespread adoption of electric cars, allowing auto Original Equipment Manufacturer (OEMs) to avoid having to rework complicated wiring diagrams for each new car and ensuring battery scalability. This article mainly focuses on the validation of an end-to-end wBMS system by performing several tests like Packet Transfer Ratio (PTR) for different configuration files, developing and implementing a health report application that generates health report in real-time, automating the process of OTA (Over the Air) upgrade which also includes automation of configuring the front-end application using a python programming language. The main intention behind developing the script to automate the OTA upgrade and health report application is to reduce the time consumed to test the system, reduce human errors, and perform the tests for any number of iterations.
