This feature ensures the safe operation of the battery during charging and discharging.

Battery Control Unit (BCU)

The Battery Control Unit (BCU) is the component of the BMS responsible for calculating and managing battery status. The ST1S14PHR electronics can calculate the battery's state-of-charge (SoC), state-of-health (SoH), state-of-performance (SoP), and state-of-preservation (SO) and communicate with the domain controller. This feature ensures efficient and safe operation of the battery.

Battery passport and incident log

Battery passports and event logs are the components of the BMS responsible for recording important parameters and tracking failures. The ST1S14 PHR electronic components are capable of recording important parameters, tracking faults, and supporting warranty clarifications. This feature ensures efficient and safe operation of the battery.

battery pack monitoring

Battery pack monitoring is a component in BMS that detects thermal runaway and monitors battery disconnection, isolation and overcurrent. The ST1S14PHR electronics can detect thermal runaway, monitor battery disconnection, isolation and overcurrent, and disconnect if necessary. This function ensures safe operation of the battery.

Battery disconnection and protection

Battery disconnection and protection are the components of the BMS responsible for ensuring the safety of electric vehicles during parking, charging and discharging. The ST1S14 PHR electronic components ensure the safety of electric vehicles during parking, charging and discharging, disconnecting the charger and monitoring the disconnected status of the monitor. This feature ensures efficient and safe operation of the battery.

isolated communication

Isolated communications are the component of the BMS responsible for reliably transmitting battery information between the high voltage and low voltage domains using wired (ISO-UART) and wireless (Bluetooth Low Energy) topologies. The ST1 S14PHR electronic component is capable of reliably transmitting battery information between high voltage and low voltage domains using wired and wireless topologies. This feature ensures efficient and safe operation of the battery.

interoperability and flexibility

Interoperability and flexibility are the components of BMS responsible for reducing design effort and accelerating application time-to-market. ST1S14PHR electronic components provide interoperability and flexibility, reduce design effort and speed application time-to-market. This feature ensures efficient and safe operation of the battery.
