The device can be used to measure divided down high voltage nodes in a battery system. It can measure voltage across Fuse, Contactors and check isolation voltage in a battery junction box (BJB) system. The device has two integrated current sense (BQ79731-Q1) paths supporting low-side shunt resistor. Coulomb counting (BQ79731-Q1) function is available for accurate SOC calculation. There are 15 GPIOs/auxiliary inputs that can be used for HV measurements, thermistor measurements, and driving relays. There are four SW outputs that can be used to drive MOSFET switches in the measurement path. The device can function as a SPI HUB and interface with up to eight separate SPI devices/groups. Over current protection response can be achieved autonomously using HW pins for fast protection in dangerous over current events. The isolated bi-directional daisy chain ports support both capacitor and transformer based isolation. The device can also communicate with MCU over SPI and UART.

The BQ79731Q1EVM evaluation module (EVM) also referred to as BMS060 describes the general features, theory of operation, hardware setup, and use of BQ7973x-Q1. These are highly integrated voltage, current and insulation resistance monitor devices primarily used in a battery junction box (BJB) (...)
The Battery Cell Simulator (BCS) is the core of any test Battery Management System (BMS). It allows the simulation of all required states and faults for the BMS on the cell level.
This reference design is a high-voltage, current and insulation impedance accuracy lithium-ion (Li-ion), LiFePO4 battery rack. The design monitors four high-voltage bus inputs, one shunt current and temperature, and one insulation impedance of the battery. The design protects the battery rack to (...)
