BERNACHEZ G ¨ / RARD

The invention relates to a distributed battery management system of an electric vehicle. A distributed battery management system for a multi-module traction battery pack for an electric vehicle is provided. A battery management system includes an analog-to-digital converter (ADC) integrated into a battery module of a traction battery pack of an electric vehicle, and a master controller external to the battery module and in digital data communication with the ADC. The ADC converts an analog signal indicative of a sensed voltage associated with one or more cells of the battery module to a digital signal indicative of the sensed voltage. The main controller performs a function associated with a traction battery pack of the electric vehicle based on the sensed voltage.

本公开涉及电动车辆的分布式电池管理系统。提供了一种用于电动车辆的多模块牵引电池组的分布式电池管理系统。电池管理系统包括集成到电动车辆的牵引电池组的电池模块中的模数转换器(ADC)，以及电池模块外部的并且与ADC进行数字数据通信的主控制器。ADC将指示与电池模块的一个或多个单元相关联的感测电压的模拟信号转换为指示感测电压的数字信号。主控制器基于感测电压执行与电动车辆的牵引电池组相关联的功能。
