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

Features of Tesla BMS battery management system Tesla battery management system BMS adopts a master-slave architecture design, and the master controller (BMU) is responsible for high voltage, insulation testing, high voltage interlock, contactor control, and external communication. The slave controller (BMB) is responsible for cell voltage and temperature testing, and reports to the BMU. 1.4416 low-capacity small 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. The Tesla BMS battery management system has a high risk tolerance. How important is it to maximize the use of big data to maintain and manage a large number of battery cell BMS functions? BMS is the lifeblood of electric vehicles! BMS is the link between the battery and the vehicle. The signals it solves are rich enough, including: batteries, collisions, CAN, charging, water pumps, high voltages, insulation, and so on. An over-discharge will cause permanent damage to the battery. In extreme cases, overheating or overcharging of the lithium battery can cause thermal runaway, battery breakage or even explosion. Therefore, the BMS must strictly control the charge and discharge, and guard against overcharge, overdischarge, and overheating.
