An electronic component known as a “EV safety monitoring IC,” also known as a “integrated circuit,” is made especially to manage and monitor an electric vehicle’s safety. (EV).
These ICs are frequently used in battery management systems (BMS) to make sure the battery pack is working within safe parameters and to stop hazardous conditions like overcharging, overdischarging, and short circuits.
A typical EV safety tracking IC may have the following features:Monitoring of cell voltage: The IC will keep an eye on the voltage of each battery cell in the pack to make sure it stays within safe ranges. Monitoring of the battery pack’s temperature by the IC will prevent it from burning or becoming too chilly.
Cell balancing: To make sure that all of the cells in the battery have the same voltage, the IC may be able to balance the voltage of individual cells.
Communication interface: To interact with other BMS components or with an outside monitoring system, the IC may have a communication interface.The safe and dependable operation of an electric car is ultimately dependent on an EV safety monitoring IC.
Global EV safety monitoring IC market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Texas Instruments (TI) introduced two extremely precise EV charge monitoring ICs at CES the BQ79718-Q1 and the BQ79731-Q1 The BQ79718-Q1 allows for a larger effective range for EVs thanks to its OCV measurement accuracy of 1 mV.
Battery pack current reading on the BQ79731-Q1 is accurate to 0.05% . The battery management system (BMS) of the EV can watch the battery pack’s power instantly thanks to the devices’ ability to synchronise voltage and current at a rate of 64 microseconds According to TI this allows a real-time snapshot of battery health.
