The Battery sensing and monitoring system consists of three sensors: (i) current sensor, (ii) voltage sensor, and (iii) temperature sensor. The three sensor signals are read by analog-to-digital converters (ADCs), processed by a programmable STM32 microcontroller, and provided at the output via the CAN interface. A particular feature of the product is its independent power supply and galvanically insulated design. Therefore the device operates directly with 12V DC and can be attached on both high-side and low-side of the high voltage (HV) battery system.
