Battery Management System
Tesla’s BMS continuously monitors high-voltage battery state of charge and can reset brick-level SoC with open-circuit-voltage measurements to support energy estimates. It also runs Battery Health testing to assess energy retention against expected performance by battery type, age, and use, and service software includes an SoH routine for high-voltage batteries.
