Competition among Chinese BMS manufacturers is fierce, with significant differences in technology level and scale

In China, competition among battery management system (BMS) manufacturers is fierce, with significant differences in their scale, technology levels and talent pools. BMS is a system that senses, manages and protects the voltage, current, temperature, etc. of the battery pack. It plays an important role in battery pack balance management and thermal management. Since BMS has an in-depth need to understand the electrochemical change process of batteries, some leading power battery manufacturers have theoretical advantages in this regard. Although some components of new energy vehicles are mainly provided by third-party suppliers, BMS, as the "brain" of the battery system, is an important link connecting the battery pack, vehicle system and motor, and is composed of the power battery and vehicle control system. The three core technologies of new energy vehicles.
