What are the characteristics of Tesla's BMS battery management system

Tesla's battery management system BMS adopts a master-slave architecture design, and the master controller (BMU) is responsible for functions such as high voltage, insulation test, high voltage interlock, contactor control, and external communication. The slave controller (BMB) is responsible for the cell voltage and temperature test, and reports to the BMU. 1.4416 small low-capacity batteries support a 75kWh system, and a large number of small batteries make the battery system more stable. 2. Although the battery is purchased, Tesla has developed its own management system to manage the temperature of each battery cell. 3. The two-stage method is adopted to balance the cells to obtain higher battery utilization efficiency and have a relatively low attenuation speed. 4. Tesla reduces the relative flammability of NCA batteries by using non-conductive materials and embedded thermometers. 5. Tesla has accumulated relevant experience data related to BMS: driving, charging, battery temperature, battery capacity changes, etc. 6. Tesla’s BMS battery management system has a high risk tolerance and makes the most of big data to maintain and manage a large number of batteries.
